Description
Technical Field
The utility model relates to the technical field of vibration absorbers, in particular to a buffer sealing cover of a vibration absorber.
Background
The automobile shock absorber is an important component part of an automobile chassis and is also a core for adjusting the automobile chassis. New energy vehicle types popular with the masses in recent years are popular with domestic customers. However, the operability and comfort of the automobile chassis are limited by the structure, so that the automobile chassis cannot be compared with the traditional fuel car, particularly in the aspect of automobile noise, and the noise evaluation of other parts is more severe because the automobile chassis has no noise interference of an engine and a transmission. There is a need for improved vibration damping and noise absorbing properties of vibration dampers.
Disclosure of Invention
The utility model provides a buffer sealing cover of a shock absorber, which aims to overcome the defects of the prior art.
In order to achieve the above purpose, a buffer sealing cover of a shock absorber is designed, which is characterized in that: the inner cover is fixed in the cavity through the fixing buckle.
The top of the outer cover is provided with an exhaust groove.
The buffer layer is a corrugated elastic layer.
The annular metal framework is embedded in the bottom of the outer cover.
The outer cover is made of polyurethane elastic material.
The inner cover is a metal stamping part.
The top of the inner cover is provided with a supporting convex hull.
Compared with the prior art, the buffer layer is arranged on the outer cover through the matching of the inner cover and the outer cover, so that the buffer performance of the top of the buffer sealing cover of the shock absorber is ensured, noise is absorbed, and the sealing performance of the cover is ensured.

Fig. 4 is a sectional view of the outer cap.
Fig. 5 is a perspective view of the inner cap.
Fig. 6 is a schematic view of the installation of the present utility model.
Referring to fig. 1 to 6, 1 is an outer cap, 1-1 is an exhaust groove, 1-2 is a buffer layer, 1-3 is a metal skeleton, 1-4 is a fixing buckle, 1-5 is a piston rod through hole, 2 is an inner cap, 2-1 is a supporting convex hull, 3 is a damper cylinder, and 4 is a piston rod.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1-6, a buffer layer 1-2 is arranged above an outer cover 1, a piston rod through hole 1-5 is arranged in the middle of the outer cover 1, a cavity structure is arranged below the outer cover 1, a fixing buckle 1-4 is arranged on the inner side of the bottom of the cavity, and the fixing buckle 1-4 fixes the inner cover 2 in the cavity. The inner cover 2 is connected with the top of the damper cylinder 3 in a mounting way, the outer cover 1 is sleeved on the outer side of the inner cover 2, the piston rod 4 passes through the piston rod through hole 1-5, the top of the outer cover 1 is contacted with a buffer block of the damper when the damper is compressed, and the buffer layer 1-2 increases the buffer performance of the sealing cover. As shown in fig. 4, the fixing buckles 1-4 are triangular reverse buckles and can be uniformly distributed on the inner side of the bottom of the outer cover 1 to fix the inner cover 2.
The top of the outer cover 1 is provided with an exhaust groove 1-1. When the sealing cover is extruded by the buffer block of the shock absorber, air in the inner cavity of the buffer block is extruded, and can be discharged from the exhaust groove 1-1, so that noise is reduced.
The buffer layer 1-2 is a corrugated elastic layer. Cushioning layer 1-2 may compress cushioning at the pleats.
The annular metal framework 1-3 is embedded in the bottom of the outer cover 1. The metal framework 1-3 can strengthen the strength of the fixing buckle 1-4, so that the fixing buckle 1-4 of the outer cover 1 is not easy to loosen when the inner cover 2 is buckled.
The outer cover 1 is made of polyurethane elastic material. The elastic material gives the outer cover 1 the effects of vibration damping and noise absorbing.
The inner cap 2 is a metal stamping. For fitting with the damper cylinder 3.
The top of the inner cover 2 is provided with a supporting convex hull 2-1. The supporting convex hull 2-1 can strengthen the strength of the inner cap 1, and when the inner cap 1 and the outer cap 2 are pressed, the inner cap 2 and the outer cap 1 can be installed in an interference mode, and the whole circumferential surface is not contacted, so that the installation is too difficult.
When the utility model is used, the inner cover 2 is fixed in the cavity below the outer cover 1 through the fixing buckles 1-4 below the outer cover 1. The inner cover 2, the outer cover 1 and the shock absorber cylinder barrel 3 are all in interference fit, the supporting convex hull 9 can play a role of a reinforcing rib, and the whole circumferential face is not contacted, so that the installation is too difficult. When the shock absorber works, the sealing cover can be extruded and impacted by the buffer block, air in the cavity inside the buffer block is extruded and can be discharged from the exhaust groove 1-1, air squeaking can be avoided, the buffer layer 1-2 is made of a corrugated polyurethane elastic material, and the shock absorber can compress and buffer when being extruded, absorb part of impact energy and play a role in damping and absorbing noise.
