Description

Heat shield

Technical field

The application relates to a kind of heat shield, is used for shielding thermal region, for instance, the thermal region of internal combustion engine。Such heat shield generally includes at least one sheet-metal layers。This sheet-metal layers decreases thermal source and is sent distributing of heat from it towards the hot side of thermal region to the cold side away from thermal region, thus decreases heat transfer。Additionally, such heat shield provide not only the minimizing from the hot surface of heat shield to the heat transfer on cold surface, and inhibit the transmission of vibration from the side of heat shield to opposite side。

Background technology

In other embodiments, such heat shield includes at least two metallic plate, and the two metallic plate is connected to each other at least in part, for instance, the outward flange along them is connected to each other。Such as, by the edge of a layer is formed a kind of crimping around the edge fold of another layer, it is possible to achieve such connection。The two flaggy so forms housing, wherein can comprise other intermediate layer (so-called side's eye net (filet)), for instance, as granule or as the soft material of rolled-up stock, paper, fibre and wool and Muscovitum, expansion Muscovitum, graphite or expanded graphite。

Generally, such heat shield or its metallic plate include the hole as passway, and this some holes is through to a few metallic plate。When seated, this some holes can use secure component (such as, screw), and this secure component can make heat shield be fastened on internal combustion engine or be fastened in internal combustion engine。

These secure components are typically attached to corresponding parts, for instance, internal combustion engine。This can make secure component that from these parts, vibration and heat are delivered to heat shield。Therefore, there is the resolution element of multiple heat and vibration for separating transmission from secure component to heat shield。The silk pad etc. being made up of the line weaving etc. is widely used as resolution element。

Such line fabric is on the one hand much more expensive, has sizable weight on the other hand, and this is to be disadvantageous for light-weight metal heat shield。

Other disadvantage is that, owing to such resolution element must be installed from the both sides of heat shield, therefore so the installation of resolution element bothers。Additionally, except heat shield and secure component, it is necessary to have resolution element and all these elements are provided for skilled worker individually in infield。

Installing such resolution element for skilled worker is another challenge。

Summary of the invention

Therefore, it is an object of the invention to provide heat shield that is a kind of cost-effective, lightweight and that be easily installed resolution element, this resolution element makes heat shield isolation heat and/or vibration。Another main purpose of the present invention is long-term stability and economic benefit。

This purpose is realized by heat shield according to claim 1。Give advantageous embodiment in the dependent claims。

Heat shield according to the present invention is primarily adapted for use in the application in internal combustion engine and its auxiliary unit。It is especially advantageous for design light-weight metal heat shield, for instance, the aluminium heat dissipator according to the present invention。

Heat shield according to the present invention can be installed in a rapid and simple manner。This can also limit mounting cost。According to practical situation, it is possible to select between the embodiment of resolution element resolution element being pre-installed on heat shield or inserting during heat shield installation。The heat shield according to the present invention owing to having the resolution element of pre-installation can install heat shield without inserting other parts, being absent from the deformation of any element and have extremely short cycle time, therefore this heat shield is particularly advantageous。

Heat shield according to the present invention includes at least one sheet-metal layers, and this sheet-metal layers has at least one passway for secure component。According to the present invention, resolution element inserts this passway。Resolution element can at least part of separation or the hot transmission with vibration from secure component to heat shield of suppression。To achieve it, resolution element includes holding element and clamping element。Holding element is shelved on the side of at least one metallic plate of heat shield。For this, holding element needs to be positioned at the outside in the region of the passway for secure component, thus is positioned in the region of metallic plate。Resolution element also includes clamping element, this clamping element runs through the hole in metallic plate and is shelved on another surface of described metallic plate, if or this clamping element runs through the hole in more than one sheet-metal layers, then the opposite side of that sheet-metal layers farthest being shelved in described more than one sheet-metal layers。

This some holes is also positioned on the outside of the passway for secure component。From the surface that there is a holding element location, clamping element runs through in metallic plate another surface that the hole of a metallic plate, multiple metallic plate or whole metallic plates arrives the described metallic plate (clamping element already by metallic plate) of heat shield。Can also is that clamping element does not extend through whole metallic plates of heat shield but is shelved between two adjacent metallic plates。This causes that resolution element is fastened in a form-locking manner, and resolution element can be made to be simply mounted in the passway of heat shield。

Holding element and clamping element can be connected to the central base element in the region, passway of resolution element by connecting element, and this connecting element radially extends relative to passway。Therefore, holding element and clamping element can radially be positioned to the central base interelement with resolution element separated by a distance。

Seat element is advantageously arranged in the passway of each metallic plate or is arranged in the passway of heat shield。If seat element is arranged to disc-shape, especially it is arranged to the circular element existed in concentric fashion with passway, is then particularly advantageous。Preferably, seat element includes opening, and this opening can adopt secure component with the passway arranged concentric in heat shield and permission。The external diameter of seat element is smaller than the inner width of the passway of metallic plate, to allow seat element to be fully disposed in the region of passway。

If heat shield has significant asymmetrical vibration, centrifugal layout (such as by oval-shaped passageway mouth) is advantageous for。Such as, such nonsymmetrical vibration may be from the interaction between different fastening area。

If in the metal sheet plane of the heat shield that seat element is disposed in the passway of metallic plate, then this is especially advantageous。Therefore, the connecting element radially extended can bend by this way: these connecting elements are either directly or indirectly transitioned in holding element, and the clamping element on the same surface of metallic plate or heat shield is also such。Therefore, clamping element has integral type crank, it allows clamping element to run through the hole in metallic plate or the hole in heat shield, the free end making clamping element is clamped to the farthest surface of metallic plate from another surface of metallic plate, and it runs through this hole and causes that resolution element is connected with the form-lock of metallic plate or heat shield。

Owing to heat shield includes more than one layer, therefore advantageously: clamping element runs through whole layer (including non-metallic layer), and the free end of clamping element is shelved on outermost farthest surface, is so positioned on another surface of heat shield。In other cases, it is advantageous that clamping element only runs through some layers (only running through a metal level under most extreme case), and the free end of clamping element be shelved on the opposite side of a farthest sheet-metal layers of its described layer run through。This means that the part in the hole run through in metal level of clamping element still can be capped by least one of which of heat shield。

In order to optimize separating effect or offset the strong asymmetrical vibration of heat shield, design connecting element with asymmetric manner and be advantageous for。Such as, different spacing can be set between different pairs of adjacent connection elements。In the same way, the height of crank can be different。Additionally, the width of connecting element, especially the width of the connecting element in the region of crank can change, for instance connecting element can include waist。

Additionally, for completely or only some holding elements and/or completely or only some clamping elements, holding element and clamping element can be arranged to have similar and different radial distance from passway。For completely or only some holding elements and/or completely or only some clamping elements, they are extensible to identical circumferential direction or contrary circumferential direction。Length finally, for completely or only some holding elements and/or completely or only some clamping elements, holding element and clamping element can select independently。

(on the one hand) contacting between holding element and clamping element with the adjacent metal plate of (on the other hand) heat shield is improved also by integrated half flange (crank) on the bearing of trend of holding element and/or clamping element or in the end of holding element and/or clamping element or full flange。These half flanges or full flange provide the Elastic Contact between holding element and clamping element and each contiguous metallic plate。Meanwhile, resolution element on heat shield or the contact area between being fastened with the part of heat shield reduce, thus causing that heat transfer reduces。

The concrete advantage of resolution element results from the fact that: compared with bayonet connection, and this resolution element can be mounted by screwing in an extremely simple manner。By the crank being positioned between element and clamping element transition position, after being fixed on another part by heat shield, resolution element itself can not unclamp from passway。Thus this design provides a kind of particularly stable and reliable connection between resolution element and the metallic plate of heat shield。

Present invention particularly includes two alternative embodiments: when installing resolution element in the production scene of heat shield, secure component is fastened on heat shield in the way of anti-loosening；Or when heat shield is fastened to adjacent part, resolution element carries out installing in the production scene of heat shield and tightening member is merely inserted into。For latter embodiment, by prior art it is known that screw or bolt can be used as secure component。

Advantageously, secure component is disposed in the opening of resolution element in anti-loosening but still moveable mode。Especially preferably, this can by utilizing screw to realize as secure component。By this way, it is no longer necessary to must provide for being responsible for using independent secure component to install the skilled worker of heat shield。Owing to secure component is provided together with heat shield and resolution element, therefore secure component also can be removed the burden of skilled worker and can mode be secured in this part easily。This embodiment also prevents heavy individually preserving and configuration, and also avoid the risk using inappropriate secure component。

Preferred use screw is as anti-loosening secure component。Screw can pivotally be supported in passway。If screw is additionally moveable in the channel direction of opening, then this is advantageous for。For screw, heat shield can be placed on the position for installing by skilled worker, and is absent from by the risk causing screw loosening that comes off on the rightabout of parts。Therefore, after screw in place, can install immediately by screwing in。

According to the present invention, if screw has the bar between the head and screw thread of screw, the diameter that this bar has is less than adjacent thread, then screw can be arranged in the opening of resolution element in a movable manner。If this region that diameter reduces has been inserted in the corresponding slype mouth of heat shield or resolution element, then screw itself can not come off from passway。

In another advantageous embodiment, screw is the screw bolt with biasing, thus screw bolt has two regions of screw thread of different-diameter, and it is only provided with screw head after bolt is inserted heat shield, for instance by screwing in。

Preferably, the secure component arranged in the way of anti-loosening is arranged by prestretched on the direction of head of screw, for instance by being bearing on spring。So, screw extrudes backward, selects according to the suitable of length of the bar of screw, and this makes screw stretch out from the passway of heat shield on its part direction to be installed。During heat shield is installed, this prevents screw from stretching out towards the part of the definite location that will hinder heat shield。After positioning, screw can be fixed in corresponding box thread in the portion to overcome prestretched。Owing to spring prevents the movement that screw gravity on this part direction causes, if therefore install and level must carry out or carry out from above, then this is particularly advantageous。

Such spring provides anti-screw loosening and removable another feasibility installed in opening。For this, spring can be connected to head of screw and opening or resolution element with the form of form-lock and/or bonding mode。Spring extrusion screw head, therefore whole spring is axially away from the metallic plate of heat shield, but prevents screw from coming off from passway。

Utilize the heat shield of two-layer or multilamellar, it is advantageous to the passway in metallic plate is arranged in such region: in this region, between metallic plate, do not arrange other intermediate layer。This makes the fabulous pressure locking of heat shield in the part be provided with heat shield connect。

Compared with the conventional heat shields 1 of the resolution element 10 with routine described in Fig. 1, Fig. 2 illustrates the resolution element 10 according to the present invention。The seat element 11 with circular outer diameter is included as this resolution element 10 of the first element。Seat element 11 includes opening 20, and opening 20 is arranged concentrically in the passway 3 of heat shield 1 (referring to Fig. 1) in the installment state of resolution element。In fig. 2, opening 10 has the outward flange 21 of hexagonal shape, and this can make resolution element 20 be rotated around the passage axis of opening 20 by hexagonal wrench。

The arm 12a of three radial directions, arm 12b and arm 12c separate from seat element 11, and each radial arm biases 120 ° around the medial axis of seat element 11。Arm 12a, arm 12b radially and arm 12c extends in radial directions from seat element 11。From seat element 11 to arm 12a, each transition position of arm 12b and arm 12c, be provided with crank 13a, crank 13b and crank 13c。At the radial edges place of arm 12a, arm 12b and arm 12c, each arm 12a, arm 12b and arm 12c are divided into Liang Ge branch 14a and 16a, Liang Ge branch 14b and 16b, Liang Ge branch 14c and 16c, and these branches extend all along the circumferential direction of seat element 11。Branch 14a, branch 14b and branch 14c serve as keeping arm, and substantially extend in the plane that crank 13a, crank 13b and crank 13c limit, and therefore extend in the plane of the arm 12a radially extended, arm 12b and arm 12c。Compared with other branches, it is used as clamping element 16a, clamping element 16b and clamping element 16c from arm 12a, arm 12b radially and arm 12c in diametrically opposite upwardly extending branch of side。Crank 17a, crank 17b and crank 17c, make clamping element 16a, clamping element 16b and clamping element 16c from connecting element 12a, connecting element 12b and connecting element 12c towards the plane bias of seat element 11。Free end at these clamping elements 16a, 16b and 16c, including other crank or half flange 18a, 18b and 18c, when they are compared with arm 12a, arm 12b and arm 12c, crank 18a, crank 18b point to the direction identical with crank 17a, crank 17b and crank 17c with crank 18c。

In the examples below, heat shield 1 itself is illustrated as oblong object。But, heat shield can have various shape。The purpose that the selected elliptical shape with its simple form is merely to illustrate。

Fig. 3 illustrates resolution element 10, and this resolution element 10 is secured to the sheet-metal layers 2 of heat shield 1。Heat shield 1 include three radially extend and the hole concentric with passway 20 or seam 6a, 6b and 6c。In fig. 2, resolution element 10 is illustrated to be arranged in heat shield 1。For this, the resolution element 11 with clamping limb 16a, clamping limb 16b and clamping limb 16c is positioned in the correct position on sheet-metal layers 2, then makes clamping limb 16a, clamping limb 16b and clamping limb 16c run through seam 6a, stitch 6b and stitch 6c and be bonded on another surface of sheet-metal layers 2 rotationally clockwise。So, resolution element 10 is fastened firmly to sheet-metal layers 2。In the illustrated embodiment, resolution element Main Function is thermal release。

Fig. 4 illustrates the top view of another heat shield 1, and this heat shield 1 includes the resolution element 10 similar with the resolution element in Fig. 3。Compared with Fig. 2, the external diameter of seat element 11 herein is less than the unsupported width of the passway 3 of sheet-metal layers 2。Therefore, the seat element 11 of resolution element 10 is away from the outward flange of passway 3。This further improves separating between secure component and the sheet-metal layers 2 of fastening in opening 20。

Figure 5 illustrates the heat shield identical with the heat shield of Fig. 4, but, packing ring 9 and the screw 5 with screw head 7 have been positioned on seat element 11。In this condition, heat shield 1 can be threaded into another parts, and wherein about the transmission of heat at least largely and vibration, these parts and screw are separated with the metallic plate 2 of heat shield 1 by the resolution element 10 being arranged in passway 3。

Fig. 6 illustrates the top view of another resolution element 10 similar with the resolution element shown in Fig. 2。Herein and below in two embodiments, resolution element is not specifically shows at the crank 13a in connecting element l2a, connecting element 12b and connecting element 12c region, crank 13b and crank 13c。Fig. 6 main purpose is in that to compare with two embodiments hereafter。

Fig. 7 illustrates the top view of another resolution element according to the present invention, and it has four keeping arm 14a, 14b, 14c and 14d and four clamping limb 16a, 16b, 16c and 16d。

Compared with Fig. 2 and Fig. 6, in this resolution element 10, the position of the position of holding element 14a, holding element 14b, holding element 14c and holding element 14d and clamping limb 16a, clamping limb 16b, clamping limb 16c and clamping limb 16d exchanges。Additionally, this resolution element 10 is similar in design。It is only that the end of holding element 14a, holding element 14b, holding element 14c and holding element 14d is provided with breach with the end of clamping limb 16a, clamping limb 16b, clamping limb 16c and clamping limb 16d。

Fig. 8 illustrates other resolution element 10 of two similar with the resolution element in Fig. 6 with Fig. 8 A and Fig. 8 B。But, the two resolution element illustrates asymmetrical design。

In Fig. 8 A embodiment provided, arm 12b radially is designed to different from arm 12a radially and arm 12c。Arm 12b radially illustrates waist and groove 22。By this way, compared with other two arm 12a and 12c, arm 12b is more soft and more flexible。Additionally, this arm 12b vibrates in the frequency range different from arm 12a and arm 12c。This provides the asymmetric decoupling of vibration。It addition, opening 20 herein is designed to circular open rather than hexagonal apertures。The mode that the keeping arm 14a of the resolution element 10 in Fig. 8 A, keeping arm 14b and keeping arm 14c can also tilt is designed, and this causes that these keeping arms are projected in the region between clamping limb 16a, clamping limb 16b on the one hand and clamping limb 16c and seat element 11 on the other hand。

The free end 18a of keeping arm 14a, keeping arm 14b and keeping arm 14c, free end 18b and free end 18c also can increase, form the contact surface of keeping arm 14a, keeping arm 14b and keeping arm 14c, this contact surface is disposed adjacent to opening 20 on the one hand, provides firmly shelving of these arms on the other hand。

Fig. 8 B also shows that the asymmetrical embodiment of resolution element 10。On the one hand, opening 20 herein is embodied as slotted eye, and it allows the non-concentric of secure component to insert。On the other hand, compared with the 3rd arm 12c, arm 12a and arm 12b relative to each other has a less spacing, and the length of the length of keeping arm 14a, 14b and 14c and clamping limb 16a, 16b and 16c is applicable to this thus has different length。This also leads to the decoupling of asymmetrical vibration。

Fig. 9 illustrates another resolution element 2, and this resolution element is similar to the resolution element in Fig. 2 in design。In fig .9, the screw 5 with bar 8 is additionally disposed in resolution element。The bar 8 of screw 5 is surrounded by spring 25。This spring is closely attached on head 7 or the axle collar 27 of screw 5。In an identical manner, the other end of spring is connected with resolution element 10。So, screw 5 is arranged in opening 3 and opening 20 in the way of anti-loosening。Spring 25 is attached to the head 7 of screw 5 and spring itself can not be unclamped from screw 5, but the head of screw 7 can rotate relative to spring。Therefore, and continuously screw 5 can be screwed in adjacent parts by passway 3 against the power extrusion screw 5 of spring 25。Due to the prestretched of spring, thus the head of the screw of no-load condition promoted and far as possible from heat shield 1 so that according to the appropriately selected length of bar 8, the bar 8 of this screw 5 does not protrude past sheet-metal layers 2。

This helps avoid during the location at parts place, and heat shield 1 is stuck in the protuberance of these parts or similar position, thus hindering the heat shield 1 installation on parts。In fig .9, heat shield itself is not shown more clearly to provide this figure。

Figure 10 illustrates another embodiment of the resolution element 2 according to the present invention with rotational symmetry。Here, holding element 14a, 14b and 14c constitute the radial direction triangle adnexa of connecting element 12a, 12b and 12c, wherein, connecting element 12a, 12b and 12c are connected to holding element 14a, 14b and 14c at a most advanced and sophisticated place of the holding element 14a of triangle, 14b and 14c respectively。Then the tip adjacent with above-mentioned tip extend into clamping element 16a, 16b and 16c。Clamping element 16 is designed to similar with previous embodiment。

Figure 11 describes the layout in the two-layer heat shield 1 with upper strata 2a and lower floor 2b of the resolution element 2 with seat element。Sectional view away from heat insulation cap layer is corresponding with the section A-A in Figure 10。Seat element has been inserted in the passway 3 of heat shield 1。But, seat element fails to illustrate in the cross-section equally, because this section takes from clamping limb 16a。Seat element 11 is hidden in the rear of this clamping element 16a。Clamping limb 16a, 16b and 6c radially away from passway and circumference elongation are provided, but, these arms run through the hole in the upper strata 2 of heat shield 1。Describing clamping limb 16a in fig. 11, this arm runs through the hole 6 2a of upper strata from the outer surface of upper strata 2a, is then clamped on the inner surface of bottom of upper strata 2a。Thus, clamping limb 16a is to be fixed between upper strata 2a and lower floor 2b in the way of similar sandwich。Each arm in clamping limb illustrates the end section 18 of bending。
