Embodiment 1

[0015] like figure 1 As shown, the dynamic vibration absorber of the steering system in this embodiment includes a plate-shaped mounting base 6 and a mass block 1, and the mounting base 6 and the mass block 1 are connected by rubber columns 2, 3, 4, and 5. The mounting base 6 can be made of ordinary steel plates or castings. The mass of the mass block 1 is generally required to be greater than 1 / 10 of the mass of the entire steering wheel (including the steering wheel airbag). It can be preliminarily determined according to the vibration amplitude of the steering wheel at idle speed. The larger the vibration amplitude, the larger the mass of the mass block 1. Should be.

[0016] In order to facilitate the installation of the vibration absorber on the steering column, a through hole is formed in the center of the installation base 6 and the mass block 1 , wherein the through hole in the center of the installation base 6 is a self-locking threaded hole.

Abstract

The invention aims to provide a design method of a steering system dynamic vibration absorber with simple structure, low cost and convenient installation so as to solve the problem of steering wheel vibration when idling and improve vehicle riding comfort. The steering system dynamic vibration absorber comprises a plate like mounting base and a mass block which are connected by a plurality of rubber columns; by adjusting the mass of the mass block and the rubber column tangential stiffness, the tangential inherent frequency of the dynamic vibration absorber when the dynamic vibration absorber is installed in a steering system is similar to the main exciting frequency when the motor idles; the vibration of the motor when the vehicle idles is transmitted to the dynamic vibration absorber via a steering column or the steering wheel to cause the mass block to carry out sympathetic vibration and convert into heat quantity to be dissipated, thus greatly lowering vibration transmitted to the steering wheel and improving vehicle riding comfort. The absorber has small improvement of the original vehicle, has simple structure, low cost and convenient installation and is suitable for being applied to produced or designed and shaped vehicle types.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and particularly relates to a design method of a dynamic vibration absorber of a steering system. Background technique [0002] For the models that have been produced or designed, in order to solve the problem of idling steering wheel vibration caused by resonance, there are usually the following two methods: one is to increase the natural frequency of the steering system by increasing the stiffness of the steering system to avoid the main engine vibration at idle speed. Excitation frequency; the other is to increase the dynamic vibration absorber in the steering system to absorb and reduce the vibration transmitted to the steering wheel. The first method needs to find weak links with low rigidity to strengthen, and the inspection cycle is long. At the same time, it may be necessary to change the structure of the instrument panel, beams and other components, which will lead to mo...
