Abstract

The invention belongs to the technical field of vehicle suspensions, and particularly relates to a torsion beam suspension structure and a vehicle. According to the torsion beam suspension structure, a rear cross beam is connected to a torsion beam welding assembly; the first end of a guide rod of the guide assembly is rotationally connected to the rear cross beam, and the second end of the guide rod is rotationally connected to a vehicle body of the vehicle and can slide in the direction of a first connecting line between the wheel center of a left wheel and the wheel center of a right wheel of the vehicle. The first end of a lateral force connecting rod of the lateral force assembly is rotationally connected to a vehicle body of the vehicle, and the second end of the lateral force connecting rod is rotationally connected between the first end and the second end of a guide rod. When a vehicle steers and wheels are subjected to lateral force, the lateral force is transmitted to a vehicle body through the torsion beam welding assembly, the guide assembly and the lateral force assembly, so that the transverse rigidity of the torsion beam suspension structure is increased, the transverse deformation of the torsion beam suspension structure is greatly reduced, and the driving stability of the rear suspension and the whole vehicle is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension, and in particular relates to a torsion beam suspension structure and a vehicle. Background technique [0002] The wheels of the vehicle are connected to the vehicle body through the suspension. In order for the suspension to ensure the precise guidance of the wheels, it is necessary to meet the requirements of light weight of the suspension under the condition of ensuring safety, and at the same time, it should also improve the ride comfort as much as possible. In the prior art, some vehicles adopt a torsion beam suspension, which directly connects the wheels and the vehicle body through the torsion beam. The torsion beam has a certain torsional stiffness, and the wheels on both sides are separated to a certain extent; at the same time, Torsion beam suspension is light in weight, simple in structure, takes up little space, and is easy to manufacture and install, so it has a large numbe...
