Automobile shock absorber

Abstract

The invention discloses an automobile shock absorber and belongs to the field of automobiles. The automobile shock absorber is arranged inside an automobile steering wheel and comprises a mass block and a rubber column under the mass block, wherein the rubber column is used for supporting the mass block; and the mass block is fixedly connected with the rubber column, and the tangential inherent frequency of the automobile shock absorber is allowed to be close to the idle-speed vibration frequency of the automobile steering wheel so as to form resonance. The automobile shock absorber of the invention effectively utilizes the inner space of the steering wheel and the tangential stiffness property of rubber and adopts a shock absorbing structure comprising the mass block and the rubber column, so that a small-size and low-frequency power shock absorber is designed and manufactured, the idle-speed vibration problem of the steering wheel is solved, and the first application of shock absorber technology in solving the vibration problem of the idle-speed steering wheel in China is realized. Comparing with the prior art, the automobile shock absorber has the advantages of simple structure, simple and convenient processing and manufacturing, short development period, low cost and convenient popularization.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile speed reducer used to solve the problem of idling vibration of the steering wheel. Background technique [0002] For models that have been produced or designed, in order to solve the problem of steering wheel idling vibration caused by resonance, the method of increasing the stiffness of the steering system is usually used to increase the natural frequency of the steering system and avoid the main excitation frequency of the engine at idle. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] The above method needs to find the weak link with low stiffness in the steering system to strengthen it. Not only the inspection period is long, but also the structure of the instrument panel beam and other components may need to be changed at the same time, which will lead to mold rep...
