[0126] Compared with the first embodiment and the second embodiment, the third embodiment differs in that:

[0127] refer to Figure 11 , Figure 11 It is a partial sectional view of the torsion beam 30, and the damping mechanism 300 includes:

[0128] Three shock absorbers 301 made of damping material, the shock absorbers 301 are connected to the first mount 310 and the second mount 320 in a direction parallel to the central axis of the beam.

[0129] When the first beam 31 and the second beam 32 are torsionally moved relative to each other, the damping member 301 is sheared and deformed, and when the first beam 31 and the second beam 32 are reciprocated and twisted around the central axis of the beam, the damping member 301 is reciprocated and sheared and deformed. . During the shear deformation process, the internal friction of the damping material consumes the energy generated by the vibration to achieve the purpose of vibration reduction.

Abstract

A torsion beam, a torsion beam type suspension, and a vehicle are provided; the torsion beam comprises a crossbeam; the crossbeam comprises a first beam and a second beam in an axial direction, and a vibration damping mechanism connecting the first beam with the second beam; the vibration damping mechanism is used for vibration damping when the first and second beams mutually twist; the crossbeam of the torsion beam can provide force supporting and stabilizing bar effects; the vibration damping mechanism can absorb energy so as to attenuate relative bounce amplitudes of left and right wheels.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a torsion beam, a torsion beam suspension and an automobile. Background technique [0002] The existing torsion beam suspension is mainly used as the rear suspension of the car, and a torsion beam is used to balance the up and down jump of the wheels on both sides, so as to reduce the roll of the vehicle and maintain the stability of the vehicle. [0003] The torsion beam suspension has many advantages such as simple structure, convenient manufacture and small space occupation. In the current technical application, the torsion beam suspension includes a torsion beam. The torsion beam is usually composed of a beam and trailing arms connected to both ends of the beam. The beam is connected to the two trailing arms to form an H shape. The rubber bushing forms a hinged connection with the body, and the rear end is connected with the hub, spring, shock absorber, etc. [0004] Th...
