A car rear axle bushing

Abstract

The invention provides a rear axle bushing of a car. The rear axle bushing comprises an outer sleeve, a rubber body, an inner sleeve, a washer, a first bracket and a second bracket, wherein the outer sleeve, the rubber body and the inner sleeve are coaxially mounted from outside to inside and are integrally vulcanized to form a gluing piece; the first end of the rubber body extends out of the outer sleeve and is designed into a rotating curved surface; a first bulged spherical surface which is distributed circumferentially is designed on the circular section of the first end of the rubber body; the first end of the rubber body is provided with a circumferential groove; the washer is arranged in the circumferential groove and surrounds the inner sleeve; the inner wall of the first end of the rubber body is provided with a strip-tooth bulge parallel to the center axis; the first bracket consists of a first circular cover body, a first insertion end and a first handle end which are integrated; the first side of the first circular cover body extends out of the first insertion end along the central axis and is inserted into the first end of the inner sleeve; the second side of the first circular cover body is provided with a first handle end along the diameter direction. The rear axle bushing of the car, which is provided by the invention, is strong in shock absorption performance and good in durability.

Description

technical field [0001] The invention relates to the field of anti-vibration technology for vehicles, in particular to a rear axle bushing for a car. Background technique [0002] With the rapid development of the economy and the substantial improvement of people's living standards, people have obviously higher requirements for the quality of life. Compared with the previous era of walking and bicycles, cars have become an indispensable means of transportation in people's lives today. Today, with the popularity of cars, people's demand for cars is not only fuel economy and vehicle safety, but also ride comfort has become the primary factor people consider when buying a car. [0003] The rear torsion beam of a car is one of the key components of a car. Its main function is to balance the up and down jump of the left and right wheels to reduce the shaking of the vehicle and keep the vehicle stable. stiffness. The rear axle bush of a car is used to connect the rear torsion be...

AI Technical Summary

Problems solved by technology

[0004] The car rear axle bushing structure in the prior art has no limit function outside the product, which cannot meet the fatigue of extreme working conditions. If a hard limit is added, the comfort will be affected

In general, durability will be lost under the premise of satisfying comfort, and comfort will be lost under the premise of satisfying durability. How to achieve a balance point is the research direction of this type of bushing design.
