Abstract

The invention discloses a bushing for an upper support of a vehicle. The bushing for the upper support of the vehicle comprises an inner side supporting part and an elastic part, wherein the inner side supporting part is provided with a main body and a plurality of first protruding parts formed on the upper surface of the main body; the elastic part wraps the inner side supporting part, a plurality of second protruding parts are formed on the surface of the elastic part at intervals, and a flat interval part is formed between every two adjacent second protruding parts, so that all the first protruding parts are covered with the interval parts. According to the bushing for the upper support of the vehicle, the elastic part is basically compressed only through the second protruding parts, so that it is guaranteed that the bushing has a good damping effect (the comfort degree is improved), it is guaranteed that the elastic part is not excessively compressed through supporting of the first protruding parts, and then the service life is prolonged ; therefore, the balance of meeting the damping effect and prolonging the service life is achieved through the bushing.

Description

technical field

[0001] The invention relates to the field of manufacture of vehicle components, in particular to the field of manufacture of bushings for supports on vehicles. Background technique

[0002] With the rapid development of the automobile industry, in order to shorten the design time and reduce the production cost, the modularization of automobile parts has become a trend. As an important part connecting the shock absorber and the body, the upper support of the shock absorber can attenuate the damping force of the shock absorber, reduce the vibration of the body, and improve comfort. In recent years, the modular design of the upper support of the shock absorber has also made great progress. There are now many upper supports on the shock absorber, which separate the metal bracket and the bushing, so that when it is applied to similar models, it only needs to be simple. Reduce development time by changing the dimensions of metal brackets and bushings.
