Embodiment 1

[0022] like figure 1 As shown, the steering system dynamic vibration absorber of 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 , 5 . The mounting base 6 can be made of common steel plates or castings. The quality 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), which can be initially determined according to the vibration amplitude of the steering wheel at idle speed. The greater the vibration amplitude, the greater the mass of the mass block 1.

[0023] For the convenience of installing the shock absorber on the steering column, the centers of the mounting base 6 and the mass block 1 are provided with through holes, wherein the through holes in the center of the mounting base 6 are self-locking threaded holes.

[0024] For the convenience of installing the shock ab...

Abstract

The invention aims to provide a steering system dynamic vibration absorber with simple structure, low cost and convenient installation and a design method thereof 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 platelike 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 manufacture, and in particular relates to the technology on how to reduce automobile vibration. Background technique [0002] For models that have been produced or have been designed, in order to solve the vibration problem of the idling steering wheel 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, and avoid the main vibration of the engine at idle The excitation frequency; the other is to add a dynamic shock 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 investigation period is long. At the same time, the structure of components such as instrument panels and beams may need to be changed, which will lead to mold repair or mold...
