Abstract

The invention relates to a torsion beam suspension structure capable of active lifting. The torsion beam suspension structure comprises a torsion beam, two suspension longitudinal arms, two shock absorber mounting support frames, two shock absorbers and a lifting and lowering driving mechanism for driving the two shock absorbers to perform synchronous opposite lifting and lowering movement, wherein the lifting and lowering driving mechanism comprises two sleeves, two driving motors, two motor bushings and two shock absorber bushings; the two sleeves are separately arranged on the two shock absorber mounting support frames in a movable and sleeving manner; one end of each of the two sleeves is fixed to the side wall of the corresponding motor bushing; the two driving motors are separately mounted in the two motor bushings in an erect manner; output shafts of the two driving motors are separately and fixedly sleeved with two first external gears; the lower ends of the two shock absorberbushings are separately and rotationally connected to the outer walls of the two sleeves; the upper ends of the two shock absorber bushings are separately and fixedly sleeved with two second externalgears which mesh with the two first external gears; the lower ends of the two shock absorbers are separately arranged in the two shock absorber bushings in a lifting and lowering manner; and the lowerends of the two shock absorbers are separately in threaded connection with the two second external gears.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an active lifting torsion beam suspension structure. Background technique [0002] At present, the traffic safety problem has become a worldwide big problem. Automobile suspension is not only an important part to ensure ride comfort, but also a general term for all force transmission connection devices between the axle (or wheel) and the frame (or load-bearing body), and it is also an important part to ensure the safety of the car. Its function It is to transmit the force and torque acting between the wheel and the frame, buffer and absorb the shock and vibration transmitted to the frame or body due to uneven roads, so as to ensure the smooth running of the car. [0003] Such as figure 1 As shown, the existing automobile torsion beam suspension generally includes a torsion beam 01, a suspension longitudinal arm 02, a spring seat 03, a coil spring 04, a shock absorber ...
