Abstract
The utility model discloses a spacer for a bolt of a valve chamber cover. The spacer comprises two layers of sheet metal frameworks (3) and a metal interlayer (5), wherein a rubber interlayer (4) is arranged between each metal framework (3) and the metal interlayer (5). By adopting the technical scheme, not only is the NVH of the valve chamber cover improved, but also the framework-type spacer can keep a pre-tightening force of the bolt better, so as to effectively seal the valve chamber; meanwhile, the damping effect is better, and the structure is simpler.
Description
Technical field
The utility model relates to a kind of automotive engine valves chamber cover cap bolt pad.
Background technique
At present, the installation of engine valve chamber cover cap is general adopts common bolt to connect, effect fixing, that tighten that this mounting type can only play, have only between valve chamber cover and the cylinder cap by valve chamber cover bolt pad and carry out buffer shock-absorbing, it is bigger that valve chamber cover is subjected to the engine luggine influence, and plain bolt is installed the influence in working life of valve cage pad also very big.
The model utility content
Problem to be solved in the utility model provides a kind of valve chamber cover bolt pad, its objective is to make that structure is more simple, effectiveness in vibration suppression is better.
To achieve these goals, the technological scheme taked of the utility model is:
This valve chamber cover bolt pad provided by the utility model comprises double layer of metal sheet skeleton and is clipped in metal sandwich between the double layer of metal sheet skeleton, is provided with channel rubber between described tinsel skeleton and metal sandwich.
Outer surface at described tinsel skeleton is provided with rubber coating.
4 location tongue-like pieces evenly are set on described tinsel skeleton.
Adopt technique scheme, not only improved the NVH of valve chamber cover, and the matrix type pad also can keep bolt pretightening better, thus sealed air valve chamber effectively, effectiveness in vibration suppression is better simultaneously, and structure is more simple.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a partial sectional view of the present utility model;
Fig. 3 is the partial sectional view of the utility model location tongue-like pieces.
Be labeled as among the figure:
1, location tongue-like pieces, 2, rubber coating, 3, the tinsel skeleton, 4, channel rubber, 5, metal sandwich.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, implementation structure is simpler, and effectiveness in vibration suppression is better.The technological scheme that the utility model is taked is:
As shown in Figure 1, this valve chamber cover bolt pad provided by the utility model comprises double layer of metal sheet skeleton 3 and is clipped in metal sandwich 5 between the double layer of metal sheet skeleton 3, is provided with channel rubber 4 between described tinsel skeleton 3 and metal sandwich 5.
Adopt technique scheme, can make the channel rubber 4 of valve chamber cover bolt pad play damping effect, tinsel skeleton 3 is played a supporting role, and can effectively keep Bolt Torque unattenuated.
Outer surface at described tinsel skeleton 3 is provided with rubber coating 2.
4 location tongue-like pieces 1 evenly are set on described tinsel skeleton 3.
Adopt technique scheme, the surface of described tinsel skeleton 3 is provided with rubber coating, also can play damping effect.
Tightly form location tongue-like pieces 1 at pad upper surface recruitment clamping, limit the thickness size of pad and the compressible amount of pad, and after guaranteeing the pad moulding, circumferential rotation in use can not take place in described tinsel skeleton 3 and metal sandwich 5, thereby the pretightening force that keeps the cyclinder head cover bonnet bolt, effective sealed air valve chamber, the multilayer rubber layer makes effectiveness in vibration suppression more obvious.
The technological scheme that the utility model adopted compared with prior art, has tangible difference, possessed substantial characteristics, and made progress technically, be worth in industrial promotion and application, so, the utlity model has novelty, creativeness and practicability.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
Claims (3)
1. valve chamber cover bolt pad, it is characterized in that: comprise double layer of metal sheet skeleton (3) and be clipped in metal sandwich (5) between the double layer of metal sheet skeleton (3), between described tinsel skeleton (3) and metal sandwich (5), be provided with channel rubber (4).
2. according to the described valve chamber cover bolt of claim 1 pad, it is characterized in that: the outer surface at described tinsel skeleton (3) is provided with rubber coating (2).
