Front cluster bushing, torsion beam axle and automobile

Abstract

The invention provides a toe-in bundling lining, a torsion beam axle and a car, wherein the toe-in bundling lining comprises an internal cylinder, an external cylinder and rubber, wherein the rubber is vulcanized and fixed between the internal cylinder and the external cylinder. The toe-in bundling lining is characterized in that the external cylinder comprises a small end face, a leading-in segment, a main body segment, an anti-interfering segment and a big end face, and the rubber comprises a hollowed-out structure, a small end rubber body, a rubber main body and a big end rubber body; the small end rubber body is matched with the small end face; the rubber main body is matched with the main body segment; and the big end rubber body is matched with the big end face. According to the toe-in bundling lining, the torsion beam axle and the car provided by the invention, the change of yawing force toe-in of a torsion beam bridge type suspension can be effectively controlled, the rubber rigidity of the lining can be lowered, the vibration and noise generated because the vehicles are shocked by the road surface in the process of running can be improved, and simultaneously, the running stability of the vehicles can be enhanced.

Description

technical field [0001] The invention relates to an automobile suspension structure, in particular to a front toe cluster bushing, a torsion beam axle and an automobile. Background technique [0002] Torsion beam axle suspension is a type of car rear suspension. It uses a torsion beam 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. The torsion beam bridge suspension is a non-independent suspension. A kind of shelf. [0003] The torsion beam bridge suspension includes torsion beam axle, shock absorber and coil spring. The front end connects the pivot with the body through the bushing on the trailing arm, and the rear side is equipped with a wheel on each side. The suspension also has cross members to withstand the lateral forces of the vehicle. [0004] However, since the torsion beam axle, wheels and tires are only connected to the vehicle body through the two bushes in front of the suspension, w...

AI Technical Summary

Problems solved by technology

[0004] However, since the torsion beam axle, wheels and tires are only connected to the vehicle body through two bushes in front of the suspension, when the vehicle is subjected to a lateral force, the toe-in of the lateral force is very large, and the toe-in of the lateral force is large at the side of the bush. The lateral displacement is also very large, which seriously affects the stability of the vehicle, especially when the vehicle is turning sharply, it is easy to cause the driver to panic. Although increasing the stiffness of the bush can reduce the lateral displacement, the vibration and noise of the vehicle It is relatively large, and the smoothness of the suspension becomes worse. In addition, since the front-rear and lateral forces are applied to the two bushes, once the bushes are deformed too much, the balance will be broken, which will seriously affect the handling stability of the vehicle.
