Description
Technical field
The application relates to a kind of thermal shield, is used for the shielding thermal region, for example, and the thermal region of internal-combustion engine.Such thermal shield generally includes at least one sheet-metal layers.This sheet-metal layers has reduced the hot side of thermal source from it towards thermal region and has sent distributing of heat to the cold side away from thermal region, thereby has reduced heat transfer.In addition, such thermal shield not only provides the minimizing from the hot surface of thermal shield to the heat transfer of cold surface, and has suppressed the transfer of vibration from a side of thermal shield to opposite side.
Background technique
In other embodiments, such thermal shield comprises at least two sheet metals, and these two sheet metals are connected to each other at least in part, for example, is connected to each other along their outward edge.For example, the edge fold that centers on another layer by the edge with one deck forms a kind of crimping, can realize such connection.These two flaggies form housing like this, wherein can comprise other mesosphere (so-called side eye net (filet)), for example, and as particle or as soft material, paper, fibre and wool and mica, expansion mica, graphite or the expanded graphite of rolled-up stock.
Usually, such thermal shield or its sheet metal comprise the hole as the passway, and at least one sheet metal is run through in these holes.When installing, secure component (for example, screw) can be used in these holes, and this secure component can make thermal shield be fastened on the internal-combustion engine or be fastened in the internal-combustion engine.
These secure components are attached to corresponding parts usually, for example, and internal-combustion engine.This can make secure component vibrate and heat is delivered to thermal shield from these parts.Therefore, there have been multiple heat for separating of transmission from the secure component to the thermal shield and the resolution element of vibration.The silk pad of being made by the line etc. of braiding waits and is widely used as resolution element.
Such line braided fabric is very expensive on the one hand, has sizable weight on the other hand, and this is to be disadvantageous for the light-weight metal thermal shield.
Another shortcoming is, because such resolution element must be from the both sides installation of thermal shield, so the installation of resolution element bothers like this.In addition, except thermal shield and secure component, also must have resolution element and provide all these elements in the infield individually for the skilled worker.
It is another challenge for the skilled worker that such resolution element is installed.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of cost-effectively, lightweight and be easy to install the thermal shield of resolution element, this resolution element makes thermal shield isolate heat and/or vibration.Another main purpose of the present invention is long-term stability and economic benefit.
By realizing this purpose according to the thermal shield of claim 1.Provided favourable mode of execution in the dependent claims.
According to thermal shield of the present invention mainly be applicable to internal-combustion engine with and auxiliary unit in application.Be especially favourable for design light-weight metal thermal shield, for example, according to aluminium heat dissipator of the present invention.
Can install in quick and simple mode according to thermal shield of the present invention.This also can limit mounting cost.According to actual conditions, can be installed in resolution element on the thermal shield in advance or insert between the thermal shield installation period between the mode of execution of resolution element and select.Owing to have according to thermal shield of the present invention thermal shield can being installed and need not to insert other parts, do not have the distortion of any element and have extremely short cycle time of resolution element of pre-installation, so this thermal shield is particularly advantageous.
Thermal shield according to the present invention comprises at least one sheet-metal layers, and this sheet-metal layers has at least one passway that is used for secure component.According to the present invention, resolution element inserts this passway.Resolution element can be at least part of separation or suppress heat and the transmission of vibration from the secure component to the thermal shield.In order to realize this point, resolution element comprises holding member and clamping element.Holding member is shelved on the side of at least one sheet metal of thermal shield.For this reason, holding member need be positioned at the outside for the zone of the passway of secure component, thereby is positioned in the zone of sheet metal.Resolution element also comprises clamping element, this clamping element runs through the hole in the sheet metal and is shelved on another surface of described sheet metal, if perhaps this clamping element runs through more than the hole in the sheet-metal layers, then be shelved on described opposite side more than that sheet-metal layers farthest in the sheet-metal layers.
These holes also are positioned at the outside for the passway of secure component.From being positioned with the surface of holding member, clamping element run through in the sheet metal sheet metal, a plurality of sheet metal or all the hole of sheet metals arrive another surface of the described sheet metal (sheet metal that clamping element has passed through) of thermal shield.Can also be that clamping element does not run through whole sheet metals of thermal shield but is shelved between two adjacent metal plates.This causes resolution element fastened in the mode of shape locking, and resolution element simply is installed in the passway of thermal shield.
Holding member and clamping element can be connected to central base element in the zone, passway of resolution element by connecting element, and this connecting element radially extends with respect to the passway.Therefore, holding member and clamping element can radially be positioned to separate distance with the central base interelement of resolution element.
Seat element advantageously is arranged in the passway of each sheet metal or is arranged in the passway of thermal shield.If seat element is arranged to disc-shape, especially be arranged to the circular element that exists with concentric manner with the passway, then be particularly advantageous.Preferably, seat element comprises opening, this opening can with thermal shield in the passway arranged concentric and allow to adopt secure component.The external diameter of seat element can be arranged in the zone of passway to allow seat element fully less than the inner width of the passway of sheet metal.
If thermal shield has significant asymmetrical vibration, centrifugal layout (for example by the oval-shaped passageway mouth) is favourable.For example, such nonsymmetrical vibration can be from the interaction between the different fastening areas.
If seat element is disposed in the sheet metal plane of the thermal shield in the passway of sheet metal, then this is especially favourable.Therefore, radially the connecting element of Yan Shening is can be by this way crooked: these connecting element directly or indirectly carry out the transition in the holding member, also are like this at the same lip-deep clamping element of sheet metal or thermal shield.Therefore, clamping element has the integral type crank, it allows clamping element to run through hole in the sheet metal or the hole in the thermal shield, make the free end of clamping element be clamped to the surface farthest of sheet metal from another surface of sheet metal, it runs through this hole and causes resolution element to be connected with the shape locking of sheet metal or thermal shield.
Because thermal shield comprises more than one deck, so advantageously: clamping element runs through whole layers (comprising non-metallic layer), and the free end of clamping element is shelved on the outermost surface farthest, is positioned at like this on another surface of thermal shield.In other cases, advantageously: clamping element only runs through some layers (only running through a metal layer under extreme case), and the free end of clamping element is shelved on the opposite side of a sheet-metal layers farthest of its described layer that runs through.The part that runs through the hole in the metal layer that this means clamping element still can be capped by one deck at least of thermal shield.
In order to optimize the strong asymmetrical vibration of separating effect or counteracting thermal shield, be favourable with asymmetric manner design connecting element.For example, between the right adjacent connecting element of difference, different spacings can be set.In the same way, the height of crank can be different.In addition, the width of connecting element, especially the width of the connecting element in the zone of crank can change, and for example connecting element can comprise waist.
In addition, for some holding members all or only and/or some clamping elements all or only, holding member and clamping element can be arranged to have similar and different radial distance from the passway.For some holding members all or only and/or some clamping elements all or only, they are extensible to identical circumferential direction or opposite circumferential direction.At last, for some holding members all or only and/or some clamping elements all or only, the length of holding member and clamping element can be selected independently.
(on the one hand) between the adjacent metal plate of holding member and clamping element and (on the other hand) thermal shield contact also can be by integrated semi-convex edge (crank) or full flange improves on the bearing of trend of holding member and/or clamping element or in the end of holding member and/or clamping element.These semi-convex edge or full flange provide the Elastic Contact between holding member and clamping element and the sheet metal that is close to separately.Simultaneously, the resolution element on the thermal shield or the area of contact that is fastened with between the part of thermal shield reduce, and reduce thereby cause conducting heat.
The concrete advantage of resolution element is from such fact: compare with the bayonet coupling part, this resolution element can be mounted by screw-in in an extremely simple manner.By being positioned at the crank of transition position between holding member and the clamping element, after being fixed on thermal shield on another part, resolution element itself can not unclamp from the passway.Thereby this design provides a kind of stable especially and be connected reliably between the sheet metal of resolution element and thermal shield.
But the present invention especially comprises the mode of execution of two alternatives: when in the production scene of thermal shield resolution element being installed, secure component is fastened on the thermal shield in anti-loosening mode; Perhaps when thermal shield was fastened to adjacent portion, resolution element was installed in the production scene of thermal shield and fastener only is inserted into.With regard to a back mode of execution, known by prior art, can use screw or bolt as secure component.
Advantageously, secure component with anti-loosening but still movably mode be disposed in the opening of resolution element.Especially preferably, this can realize as secure component by utilizing screw.By this way, no longer need to provide the responsible skilled worker who uses independent secure component that thermal shield is installed.Because secure component is provided with thermal shield and resolution element, thus secure component also can remove skilled worker's burden and easily mode be secured on this part.This mode of execution also prevents heavy independent preservation and configuration, and has also avoided using the risk of inappropriate secure component.
The preferred screw that uses is as anti-loosening secure component.Screw can be supported in the passway in rotating mode.If screw is in addition movably in the channel direction of opening, then this is favourable.For screw, the skilled worker can be placed on thermal shield for the position of installing, and does not cause the risk of screw loosening and do not exist to come off by the opposite direction at parts.Therefore, after screw is in place, can install immediately by screwing in.
According to the present invention, if screw has at the head of screw and the bar between the screw thread, the diameter that this bar has is littler than adjacent thread, and then screw can be arranged in the opening of resolution element in a movable manner.If this zone that diameter reduces has been inserted in the corresponding throat mouth of thermal shield or resolution element, then screw itself can not come off from the passway.
In another favourable mode of execution, screw is the screw bolt with biasing, thereby screw bolt has two zones of the screw thread of different-diameter, and it only provides screw head after bolt is inserted thermal shield, for example by screwing in.
Preferably, the secure component of arranging in anti-loosening mode is arranged by pre-stretching on the direction of screw head, for example by being bearing on the spring.Like this, screw pushes backward, and according to the suitable selection of the length of the bar of screw, this stretches out screw from the passway of thermal shield on its part direction to be installed.Between the thermal shield installation period, this prevents that screw from stretching out towards the part of the definite location that will hinder thermal shield.Behind the location, the corresponding box thread that screw can be fixed in this part is interior to overcome pre-stretching.Because spring prevents the movement that the gravity of screw on this part direction causes, so if install and must level carry out or carry out from the top, then this is particularly advantageous.
Such spring provides another feasibility of preventing screw loosening and removable installation in opening.For this reason, spring can be connected to screw head and opening or resolution element with the form of shape locking and/or bonding mode.Therefore spring extrusion screw head, whole spring shaft is to the sheet metal away from thermal shield, but prevents that screw from coming off from the passway.
Utilize the thermal shield of two-layer or multilayer, advantageously, the passway in the sheet metal is arranged in such zone: in this zone, do not arrange other mesosphere between sheet metal.This makes in the fabulous pressure locking connection that thermal shield on the part of thermal shield is installed.
