Abstract

The invention discloses a chassis bushing. The chassis bushing comprises an inner sleeve, an elastic sleeve sleeving the inner sleeve, an outer sleeve sleeving the elastic sleeve and assembly elementsfor changing the stiffness of the chassis bushing; the elastic sleeve is provided with more than two hole sites; the hole sites are uniformly distributed at equal intervals along the circumferentialdirection; and the assembly elements are arranged in some or all of the hole sites. According to the chassis bushing, the assembly elements of different types and different numbers can be correspondingly assembled to different hole sites to obtain required stiffness characteristic curves; and by changing the type, number and location of the assembly elements, variations in the stiffness characteristics of the chassis bushing can be quickly achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a chassis liner. Background technique [0002] The suspension system of the automobile chassis can effectively isolate and reduce the vibration excitation caused by the uneven road surface during the driving process of the automobile, and play the role of cushioning and vibration reduction. A series of car driving performances such as ride comfort, handling stability and NVH performance can be improved by improving the cushioning and damping performance of the suspension system. [0003] At present, in order to improve the buffering and damping performance of the suspension system, chassis bushings are usually provided. When installing, put the chassis bushing on the bolt to be installed, and the bolt penetrates the metal sleeve fixed on the chassis of the car (of course, it can also be other structural parts) and screw it into the corresponding bolt hole. In the casing, to...
