Description

The invention relates to a link element for the coupling connection of two assemblies, for example a wheel guide link of a motor vehicle, according to the preamble of patent claim 1.

Handlebar elements such as wishbones, trailing arm, handlebars of space bar axes and the like are used in virtually all wheel suspensions and axles of motor vehicles and serve the defined movable connection or the limitation of the degrees of freedom of movement of the wheel relative to the vehicle chassis.

In particular, in vehicle high demands are placed on such handlebar elements, including above all high load capacity and fatigue resistance, high failure safety as well as high corrosion resistance. At the same time, such link elements should also take up as little installation space as possible or allow as much freedom as possible in the shaping in order to avoid possible collisions with adjacent subassemblies. Another main requirement of generic link elements is the lowest possible component mass, which on the one hand, the curb weight and thus the fuel consumption of a motor vehicle equipped with it is reduced, and on the other hand, the unsprung masses are reduced in the suspension, which is crucial for good ride comfort and a safe road contact is.

Because of these requirements, the currently known from the prior art, in particular serving as Radführungslenker link elements are usually made of metallic materials, for example in the form of drop forged parts, cast components or as single or multi-shell deep-drawn sheet metal components.

In particular, in the production of handlebar elements as deep-drawn or forged components of the manufacturing process typically includes several forming processes. In addition, other components - in particular with regard to the storage or connection to the chassis or wheel carrier - welded to the or the strut areas such handlebar components after forming in order to fulfill all functions and to provide all necessary connection points can.

The associated, significant number of separate items and processing steps causes - despite automation technology in the production - comparatively high cost, even as after completion of the actual molding and assembly operations often also a heat treatment and a final surface treatment in the form of a usually galvanic, corrosion-protective treatment or Coating is required. Also, the deep drawing tools required for the shaping of metallic link elements are comparatively complicated and therefore expensive to manufacture. Not least, the metallic link elements used in the prior art to a relatively high mass, whereby the vehicle weight and in particular the unsprung masses of the suspension are increased.

From development projects already Radführungslenker injection molded thermoplastic materials with short fiber reinforcement or endless fiber reinforced thermoplastic and thermosetting plastics are known, which have significant weight advantages over the metallic construction of handlebar elements. However, injection-molded handlebars have not yet achieved the mechanical requirements, while prototypes made of long-fiber-reinforced plastics entail complex and therefore expensive manufacturing processes and materials. The integration of kinematic points or bearings is usually still in a conventional manner z. B. by pressing elastomeric bearings or bearing shells, which can lead to creep and thus to relaxation of the bearing seat in the handlebars made of plastics in the long run.

With this background, it is thus an object of the present invention to provide a link element with which the aforementioned existing limitations in the prior art are overcome. In particular, should be able to be represented with the invention relatively inexpensive to produce link elements, which have a particularly low mass, and thus reduce the curb weight and the unsprung masses in a motor vehicle, in which they are installed, for example, accordingly. In addition, the number of required for the link elements items as well as the number of necessary for the production of the link elements process steps should be significantly reduced, and it should be integrated or integrated with the least possible effort attachments as possible in one piece in the link elements.

This object is achieved by a link element with the features of patent claim 1.

Preferred embodiments are subject of the dependent claims.

In itself initially known manner, the handlebar element (which may be in particular, but by no means exclusively, a Radführungslenker for a motor vehicle) according to the present invention comprises at least two end areas. In this case, each end region has a bearing section, and the end regions of the link element are connected to one another by means of a strut region of the link element.

According to the invention, however, the link element is characterized in that the end regions and the strut region are formed together by a substantially box-shaped profile carrier, which is deep drawn from a continuous fiber-reinforced, plate-shaped plastic semi-finished product. At the same time, a filling body made of an injection-molded plastic is arranged in the interior of the profile carrier, wherein the filler body connects the inner surfaces of the profile carrier shear-resistant.

The constructive features of the link element according to the invention provide - due to the combination of a semifinished semi-finished (and thus basically open on one side) profile carrier with continuous fiber reinforcement on the one hand, and the inner surfaces of the profile support shear-resistant packing filler - on the other hand - a very high bending and torsional stiffness and breaking strength the handlebar element at the same time low mass safely.

This is due to the fact that the deep-drawn, unilaterally initially open - and therefore inherently torsionally soft and initially less rigid - profile carrier on the shear-resistant connection of its inner surfaces (and thus in particular its open longitudinal edges) by the filler effectively almost the properties of a large volume closed Pipe profiles, in particular a very high torsional stiffness as well as a high bending stiffness receives.

In addition, the design of the profile support completely made of plastic allows a structurally largely free and stress-optimized design for the profile support, wherein the entire manufacturing process can be designed inexpensively by means of the hybrid construction of continuous fiber reinforced profile carrier and injection-molded packing according to the invention. At the same time, a significantly reduced component mass compared to a metal beam can be achieved - with the corresponding advantages in terms of vehicle weight and unsprung mass. In addition, a whole number of manufacturing steps can be omitted as part of the production as well as the no longer necessary final heat and / or surface treatment (in particular corrosion protection or painting) of the profile carrier according to the invention.

The invention is first of all realized independently of what type and composition is the plate-shaped, continuous fiber-reinforced plastic semi-finished product and / or the injection-molded packing, as long as the material stresses arising during operation remain within the permissible range. Thus, it is conceivable, for example, to use continuous-fiber-reinforced prepregs made of thermosetting plastics such as epoxy resin for the deep-drawn profile carrier.

According to preferred embodiments of the invention, however, the material of the profile carrier is a plate-shaped semi-finished product made of a continuous fiber-reinforced thermoplastic. Such continuous fiber reinforced semi-finished products made of thermoplastic materials can (after heating) in principle be thermoformed similar to metallic sheets. The components produced in this way achieve - with suitable geometry and component design - similar stiffness and similar load capacities as corresponding metallic components, but have a mostly much lower mass than the latter on.

The use of such thermoplastic as well as continuous fiber reinforced semifinished products for the profile carrier of the link element has - in addition to the weight savings and the high specific load capacity and rigidity - the additional advantage that a profile carrier formed in this way and the filling body produced by injection molding in the initial shaping of the link element ., in the back injection of the profile carrier with the filler - intimately connect with each other by superficial melting, since both profile carrier and filler are based on an organic matrix material in the form of thermoplastic material. Last but not least, a handlebar element can be obtained in this way, which, in addition, can be recycled particularly easily and completely at the end of its service life, since it consists of thermoplastic materials in a uniform manner.

With this background, it is therefore provided according to a further embodiment of the invention that profile beam and filler are materially interconnected. This can be done in particular by the fact that the profile carrier is inserted into an injection mold and in the subsequent Urformung of the filler in the injection mold is back-injected with the material of the filler that a - at the respective contact surfaces between the profile carrier and packing - cohesive connection between the matrix material of the profile carrier and the injected during injection into the mold material of the packing results. A further preferred embodiment of the invention provides that the filler body consists of a short-fiber-reinforced or long-fiber-reinforced thermoplastic material. As a result, particularly high compressive and tensile strengths are achieved for the filler, which further increases in particular the bending and torsional rigidity of the link element.

The profile carrier can already be preformed in advance of the back injection with the filler either partially or completely - according to its final shape on the link element. Optionally, however, the shaping (deep-drawing) of the profile carrier can also be carried out - partially or completely - only when the injection mold is closed by its shaping contour, and during the subsequent injection of the material of the filling body by the injection pressure of the injection molding tool. In this way, on the one hand costs, in particular tooling costs and manufacturing time can be saved, and on the other hand so particularly good tolerance values are achieved with respect to the shape and dimensions of the finished link element, for example by any inaccuracies of a preformed profile carrier are compensated by the closing injection mold and thus eliminated.

The invention is also first realized regardless of which type and of which material is the continuous fiber reinforcement of the plate-shaped plastic semi-finished product. Preferably, however, the plate-shaped, preferably thermoplastic semi-finished plastic product contains endless glass fibers, carbon fibers and / or aramid fibers. The terms "endless" or "continuous fibers" mean that the reinforcing fibers contained in the plastic semi-finished run substantially without interruptions over the entire length and / or width of the profile carrier, resulting in each case an optimal power flow and an optimal reinforcing effect for the profile carrier. Alternatively or in addition to the reinforcement with the said continuous fibers, the semifinished plastic product may also contain metal fibers and / or at least one metal foil layer as reinforcement.

According to a further preferred embodiment of the invention, at least one bearing section of the link element comprises a pivotable bearing arrangement. In this case, the injection-molded packing connects the bearing assembly by injection with the profile carrier. In this way results - in the form of a Montagespritzgusses - a particularly simple integration of bearing assemblies such as ball joints or elastomer joints directly during injection molding of the packing. The bearing assemblies are connected in a single operation exactly at the intended location fixed to the profile carrier.

Compared to the known from the prior art press-fitting of bearing assemblies such as ball joints or elastomer joints of the injection molding has the particular advantage that during assembly no significant stresses in the bearing seat arise, which in particular in profile carriers made of plastics to creep the material and thus to Relaxation of the bearing seat can lead.

According to a further preferred embodiment, the at least one bearing arrangement comprises an elastomeric body, wherein the elastomeric body is encapsulated by the filling body. Preferably, elastomeric body and filler are cohesively connected to each other. In this way, in particular elastomer bearings - directly in the back-injection of the beam with the material of the filler - integrate by injection molding in the handlebar element, the need for a (especially metallic) outer sleeve of the elastomer bearing deleted. This also saves both assembly steps and components, and further reduces the weight of the link member. A particularly intimate cohesive connection of the outer surface of the bearing elastomer body with the filler body and thus with the link element can also be obtained by treating the surface of the elastomer body with a primer or adhesion promoter. This results in the back injection a nearly permanent bond between the elastomeric surface and the material of the packing.

According to a further embodiment of the invention, it is provided that the elastomeric body of the bearing assembly is compressed by the encapsulation with the material of the packing. In this way, in particular an elastomer bearing can already calibrate during assembly injection molding to its final intended characteristic, which usually requires a certain degree of compression of the bearing elastomer body.

A further preferred embodiment of the invention provides that the link element is designed flexurally elastic in the region of at least one bearing section. In this case, the bending elastic trained storage section is directly connected to an adjacent module. In other words, this embodiment enables the direct, pivotally movable connection of the link element, for example with the chassis of a motor vehicle, without the need for bearing elements such as, for example, elastomer joints. Instead, the at least one bending elastic running bearing portion of the link element itself fulfills the task of pivotally mounting the link element relative to the terminal assembly, for example with respect to the vehicle chassis. In this way, in particular assembly and production costs can be saved on a large scale, as well as corresponding cost scopes as well as component mass and space requirement.

The flexurally elastic mounting portion of the link element may, according to another embodiment, in particular comprise a substantially spirally formed storage area. In this way, a considerable angular mobility in the region of the flexurally elastic mounting portion can be achieved with a small space requirement. Preferably, the flexurally elastic mounting portion of the link element is formed as a laminate, wherein the laminate in the region of the storage section comprises - in addition to or alternatively to the continuous fiber reinforcement - at least one laminate layer of an elastomer material. In this way, an integral transition between the rigid portions of the link member and the flexurally elastic portions of the link member forming the bearing portion of the link member and the connection to the adjacent assembly can be achieved.

A further, particularly preferred embodiment of the invention provides that the filler body integrally comprises further functional areas, connection points, bearing points, stops or force application points for connection components or the like. Since the shape of the injection-molded packing is almost unlimited due to its method of manufacture, in this way additional functions, joints or points of application can be integrated into the link element in a particularly simple and cost-effective manner without requiring additional components and assembly steps.

According to a further preferred embodiment of the invention, the link member is a multi-point Radführungslenker with two chassis side storage sections and at least one axle leg bearing portion, in other words includes more than two end portions and thus at least three storage sections, wherein between the at least three storage sections at least one curved extending handlebar section is arranged, which connects the at least three storage sections together. Such a Radführungslenker may be (only for example) to a U-shaped, L-shaped or V-shaped wishbone. In this case, at least a part of the endless fibers of the plastic semi-finished product or profile carrier along the entire contour of the curved extending handlebar section is arranged. In this way, a preferably all bearing sections of the wheel control arm interconnecting stiffness and load optimized fiber arrangement is achieved in the finished profile beam.

A further preferred embodiment of the invention provides that the filler has a rib structure. In this case, the rib structure is substantially prismatic and also open along the Entformungsrichtung of the injection molding tool for shaping the filler or the link element arranged. The rib structure of the filler body leads on the one hand to a lower weight of the filler body and the link element, while still high torsional and bending stiffness. The prismatic design of the rib structure and its open along the Entformungsrichtung structure on the other hand lead to the injection molding tool for the shaping of the packing can inexpensively with few individual parts or parting planes, possibly only two or three parts and with only one parting plane executed.

According to a further embodiment, it is provided that the walls of the rib structure are arranged substantially diagonally diamond-shaped with respect to a longitudinal central axis of the profile carrier. Due to the diamond-shaped arrangement and - with respect to the longitudinal center axis of the profile carrier - diagonal course of the walls of the rib structure of the packing results in an effective shear stiff connection of the two edges of the continuous fiber reinforced profile carrier in the region of its open longitudinal side (in particular with respect to shear or Thrust forces), as occurs in Torsionsbelastung the profile carrier in the region of its open longitudinal side between the two local edges or longitudinal edges.

However, the invention is not limited to a diagonal or diamond-shaped design of the rib structure. Rather, the rib structure can generally be made so strength-optimized or stiffness-optimized that the alignment, number and thickness of the respective ribs are optimally adapted to the respectively prevailing force profiles or loads in the different regions of the link element. This also applies to, for example, U-shaped or generally curved or contoured handlebar course, with a correspondingly curved or contoured course of the longitudinal center axis of the link element.

According to a further possible embodiment of the invention, it is provided that the open longitudinal side of the profiled carrier produced during thermoforming of the continuous fiber-reinforced, plate-shaped plastic semifinished product is at least partially closed by a cohesively connected cover layer with the longitudinal edges of the profiled carrier present there. In this case, the cover layer in the region of the open longitudinal side of the deep-drawn profile carrier is preferably also connected in a material-bonded manner to the filling body.

The cohesive connection of the cover layer with profile carrier or packing can again by suitable process and Temperature control when applying the cover layer done, wherein the cover layer itself is preferably also formed from a plate-shaped thermoplastic semi-finished plastic product with continuous fiber reinforcement.

In this way, - in the closed with the top layer portion of the profile support - a completely closed hollow profile obtained, in which preferably also the filler is bonded cohesively with both the edges or inner walls of the profile support and with the cover layer. As a result, the torsional and bending stiffnesses of the link element can be further increased.

1 shows the profile carrier 1 a link element according to the invention, here a wishbone. It can be seen that the profile carrier is deep-drawn from a plate-shaped semifinished product. The plate-shaped semi-finished product according to the invention is a plastic semi-finished product with continuous fiber reinforcement, preferably an endless fiber-reinforced plate-shaped thermoplastic sheet. Based on the shape of the profile carrier 1 Already the bearing seats in the respective end areas 2 . 3 . 4 which can be seen for receiving elastomer bearings (Endbereiche 2 . 3 ) or a ball joint (end 4 ) are set up. It is in 1 in the end area 2 (for the sake of intuition) already an elastomeric bearing 5 arranged.

2 shows again the profile carrier 1 according to 1 , wherein the interior of the profile carrier 1 here with the filler 6 filled or injected behind. The filler 6 consists of a molded in the form of a rib structure plastic, wherein the rib structure substantially over the course of the entire (in 1 still visible) inner surfaces of the profile carrier 1 extends. In the illustrated embodiment, the filler body covered 6 the inner surfaces of the profile carrier 1 only at the actual joints between the inner surfaces of the profile carrier and the ribs of the packing 6 , While the areas located between the ribs of the inner surfaces of the profile carrier are not covered with the material of the packing. Because both the profile carrier 1 as well as the filler 6 Based on a thermoplastic matrix results - with suitable process and temperature control - in the back injection of the profile carrier 1 a cohesive connection between the inner surfaces of the profile carrier 1 and the corresponding boundary surfaces of the packing 6 by removing the inner surfaces of the profile carrier 1 during injection molding of the packing 6 be softened or melted and thus cohesively with the material of the packing 6 connect. The cohesive connection between the inner surfaces of the profile carrier 1 and the ribs of the packing 6 can be achieved, for example, that the material of the profile carrier 1 in the area of its inner surfaces - immediately before the back injection with the molten material of the packing 6 - Is heated or superficially heated by means of a heating device, for example by infrared radiation.

Already in 2 It can be seen that the elastomeric bearings in the end areas 2 . 3 and the ball joint housing in the end 4 of the wishbone by means of assembly injection molding on the basis of filling body 6 behind injected or with injected, resulting in a corresponding form or material connection between the in the end 2 . 3 . 4 arranged storage units and the packing 6 or the profile carrier 1 results.

3 shows the profile carrier 1 of the control arm according to 1 and 2 again in a plan view, here still without back injection through the packing 6 , One recognizes again the one-piece by the profile carrier 1 included end areas 2 . 3 . 4 for receiving the respective elastomeric bearings or ball joints, wherein in the end region 3 again an elastomeric bearing 5 is arranged.

In 4 is the profile carrier 1 according to 3 shown again in the finished back-injected state. Based on a synopsis of 2 to 4 is seen that the filler 6 not only the interior of the profile carrier 1 completes (cf. 2 ), but especially in the end areas 2 . 3 . 4 Also arranged there bearing elements almost all sides encloses, and thus form-fitting with the profile carrier 1 combines.

The inclusion or the formation of the ball joint housing in the end 4 of the control arm according to 1 to 4 is in 5 shown. Again, it is recognizable as the filler 6 the ball joint, or its bearing shell 7 surrounds all sides and thus simultaneously replaced or forms the ball joint housing. In addition, the packing encloses 6 also the outer shape of the bearing shell 7 partially positively overlapping, in the present case therefore approximately spherical shell-shaped indentation 8th on the profile beam 1 in the area 4 the ball joint is arranged integrally, (see also 1 ). In total, this results in a form-fitting (and due to the melting of the surface of the profile carrier 1 and possibly also the bearing shell 7 in the back injection additionally cohesive) connection between the profile support 1 and the ball joint or its bearing shell 7 ,

An alternative embodiment of a connection between the profile carrier 1 and a ball joint or a ball joint shell is in 6 shown. In the embodiment according to 6 was on the cylindrical invagination 8th (see. 5 ) omitted, resulting in the ball joint socket 4 ' a (compared to the embodiment according to 5 ) reduced positive connection between the filler 6 and the profile carrier 1 results. This embodiment is particularly suitable if, in relation to the illustration in FIG 6 - The main load direction in the storage area 4 ' drawing down.

7 shows a cross section through end or storage section 2 and elastomeric bearings 5 of the control arm according to 1 to 4 , It can be seen that the elastomeric body 9 of the elastomeric bearing 5 on all sides by the injection-molded structure of the packing 6 enclosed and thus simultaneously positive and cohesive with the profile carrier 1 connected is. A particular metallic sleeve around the elastomeric body 9 can be omitted in this way as well as the necessary in the prior art pressing the elastomeric bearing into a corresponding recess of the link element. In addition, the elastomer body 9 by the injection pressure during injection molding of the filling body 6 compressed and the elastomeric bearing 5 calibrated to its final characteristic.

The 8th to 11 show different variants of the legs or storage sections 2 . 3 alternative embodiments of a link element according to the invention 1 , where in 8th the section AA of the longitudinal sections according to 9 to 11 by a leg of the link element 1 is shown. The link elements according to 8th to 11 differ from the link element or wishbone according to 1 to 7 in particular the fact that the storage in the end areas 2 . 3 (or the connection with a respective terminal assembly) at the handlebar elements 1 according to 8th to 11 in the form of flexurally elastic end regions 2 . 3 is present. In other words, that means the end regions 2 . 3 in the embodiments according to 8th to 11 directly pivotally connected to an adjacent assembly (for example, with the chassis of a motor vehicle) can be connected without this movable bearing elements such as elastomer joints 5 . 9 (see. 7 ) required are.

Instead, the flexurally elastic end regions fulfill 2 . 3 of the link element 1 even the task of the pivotable connection of the link element 1 for example, with a vehicle chassis. In order to achieve a sufficient angular mobility of the link element 1 compared to its fixed connection, for example, with the vehicle chassis in the end 2 . 3 to allow, may be provided in particular, the respective end region 2 . 3 of the link element 1 spiral extended (see. 11 ) and / or in the region of the legs or in the end regions 2 . 3 Laminate layers of an elastomeric material in the wall of the link element 1 to integrate, which in each case a corresponding bending elasticity in the end regions 2 . 3 of the link element 1 can achieve.

As a result, it is clear that with the invention, a handlebar element made of plastic is created, which is inexpensive to produce with a minimum number of process steps and has a very low mass, at the same time high demands on the rigidity and thus the reliability are met. The unsprung masses, for example, a motor vehicle suspension can thus be significantly reduced thanks to the invention and the ride comfort can be significantly increased. The link element according to the invention may also comprise integrally various additional functions, force application points and connection components, additional assembly steps and the need for subsequent heat and / or surface treatment may be omitted.
