Abstract
The utility model discloses a damping structure for a lifting hook of an automobile exhaust system. The damping structure comprises a muffler end cover, a rubber lifting lug, and an upper lifting hook and a lower lifting hook which are connected to the rubber lifting lug, wherein the upper lifting hook is connected to an automobile body; a rubber block is arranged on the surface of the muffler end cover; and the rubber block is hooked and by the lower lifting hook for fixing. Due to the adoption of the structure, the damping structure has the advantages that firstly, in view of greater vibration acceleration of a lifting hook of an automobile exhaust system, the shearing damping action of the rubber block in the vertical direction is exerted, so as to reduce the force of the lifting hook transferred to the automobile body side to achieve the damping effect; therefore, the damping structure is helpful to reduce noises in the automobile and enhance the riding comfort; and secondly, the damping structure is helpful to refrain the vibration of the muffler end cover surface in the normal direction to reduce the radiation noise.
Description
Technical field
The utility model relates to automobile exhaust system suspension hook technical field, particularly a kind of shock-damping structure of automobile exhaust system suspension hook.
Background technology
Automobile in the process of moving, the transfer of vibration of automobile exhaust system suspension hook is given car body, influences noise and travelling comfort in the car, at present, generally be suspension hook to be arranged on the node of easy excitated mode, pass to the vibration of car body with reduction by mode finite element analysis and analysis of experiments.If but driving engine vibration itself is bigger, single hanger is not enough to damping, can cause internal car noise bigger, and travelling comfort is poor.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provides a kind of when driving engine vibration itself is big, can play fine damping effect and reduce the shock-damping structure of the automobile exhaust system suspension hook of internal car noise.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of shock-damping structure of automobile exhaust system suspension hook, comprise noise silencer end cap, rubber hanger, be connected hook and following suspension hook on the rubber hanger, described hook is connected with the car body side, described noise silencer end cover surface is provided with rubber block, and described suspension hook down hooks described rubber block to be fixed.
Described rubber block surface is extended with boss, and described boss is provided with through hole, and the coupler body of described down suspension hook lower end passes through hole and hooks described boss and fix.
Described boss is an arc boss.
Described noise silencer end cap is provided with the limiting bracket of clamping rubber block.
The thickness of described rubber block is 8mm～12mm.
Described rubber block is arranged on the outside face of noise silencer end cap.
The utility model adopts said structure, have the following advantages: 1, at the bigger situation of automobile exhaust system suspension hook vibration acceleration, the shearing damp effect of performance rubber block on vertical, thereby reduce to be delivered to the power of car body side suspension hook, reach cushioning effect, help to reduce internal car noise and improve travelling comfort; 2, help to suppress the normal vibration of noise silencer end cap face to reduce radiated noise.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a structural representation of the present utility model;
In Fig. 1,1, the noise silencer end cap; 2, rubber hanger; 3, hook; 4, following suspension hook; 5, rubber block; 6, boss; 7, limiting bracket.
The specific embodiment
A kind of as shown in Figure 1 shock-damping structure of automobile exhaust system suspension hook, comprise noise silencer end cap 1, rubber hanger 2, be connected hook 3 and following suspension hook 4 on the rubber hanger 2, hook 3 is connected with the car body side, and noise silencer end cap 1 surface is provided with rubber block 5, and it is fixing that following suspension hook 4 hooks rubber block 5.
Rubber block 5 surfaces are extended with boss 6, and boss 6 is provided with through hole, and the coupler body of following suspension hook 4 lower ends passes through hole, and to hook described boss 6 fixing.Boss 6 is an arc boss.Rubber block 5 is arranged on the outside face of noise silencer end cap 1.The thickness of rubber block 5 is 8mm～12mm, and its elastomeric material can be natural rubber, nitrile rubber, poly-chloroprene rubber, butyl rubber.Noise silencer end cap 1 is provided with the limiting bracket 7 of clamping rubber block 5.Limiting bracket 7 is welded on the noise silencer end cap 1, comes off to avoid rubber block 5.
At the bigger situation of automobile exhaust system suspension hook vibration acceleration, the shearing damp effect of performance rubber block 5 on vertical, thus reduce to be delivered to the power of car body side suspension hook, reach cushioning effect, help to reduce internal car noise and improve travelling comfort; Help to suppress the normal vibration of noise silencer end cap face simultaneously to reduce radiated noise.
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 the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
