shock absorber support

Abstract

A shock absorber upper support is provided with a channel which allows a damping rod of a shock absorber to penetrate. The shock absorber upper support comprises a spring cushion, a bearing, an elastic supporting part and an upper limiting block, wherein the bearing is partially mounted in the spring cushion; the elastic supporting part is positioned on the bearing and is propped against the bearing; the elastic supporting part comprises a first support part, a second support part and a rubber part; the second support part is positioned above the first support part; the first support part and the second support part are spaced from each other; and the first support part, the second support part and the rubber part are vulcanized together. The first support part and the second support part are partially overlapped at least in the axial direction of the shock absorber upper support. When the shock absorber upper support is subjected to an axial compression force, the rubber part is compressed, and the first support part and the second support part are propped against each other to realize self limitation.

Description

technical field [0001] The invention relates to an upper support of a shock absorber, which belongs to the technical field of automobile chassis. Background technique [0002] With the continuous improvement of people's living standards, the requirements for the comfort and handling of automobiles are getting higher and higher, so the design and performance development of automobile shock absorbing parts are particularly important. At present, the upper support of the traditional shock absorber is basically limited by the contact between the spring seat and the rubber support. However, considering the needs of the vibration isolation performance of the whole vehicle, a gap of more than 10mm will be reserved between the spring plate and the rubber support. It is used for dynamic buffering of the whole vehicle, but this gap will cause the bearing to be exposed to the external environment, causing sand, dust and rainwater to enter the bearing, resulting in premature failure of ...

AI Technical Summary

Problems solved by technology

[0003] (1) The contact between the spring plate and the rubber support is used to limit the position under extreme working conditions. However, after the spring plate contacts the rubber support, there will be problems such as difficulty in turning the vehicle, noise or even inability to turn. There is safety in extreme conditions. Hidden danger

[0004] (2) Due to the needs of the dynamic stroke of the vehicle, the traditional design must reserve a certain buffer space between the spring plate and the rubber support to improve the ride comfort of the vehicle, but this buffer space will cause the bearing to be directly exposed to the air. Lead to premature rusting and abnormal noise of the bearing, which will lead to the decline of the performance of the whole vehicle

[0005] (3) Since the spring plate not only needs to support the spring force, but also needs to provide a limit function under extreme working conditions, the strength requirements for the spring plate are relatively high. Traditional designs basically use metal stamping parts, so the product is heavy, which is not conducive to The weight of the whole vehicle is light; in consideration of anti-corrosion, the surface of stamping parts needs to be protected, such as electrophoretic paint, zinc-nickel alloy treatment, etc. These are high energy consumption and high pollution processes, which are not conducive to environmental protection
