Semi-independent automobile rear suspension

Abstract

The invention provides a semi-independent automobile rear suspension and belongs to the technical field of vehicles. The semi-independent automobile rear suspension comprises a left dragging arm, a right dragging arm, a beam and movable connecting pieces. The two ends of the beam are movably connected with the left dragging arm and the right dragging arm through the movable connecting pieces respectively. Due to the fact that the left dragging arm and the right dragging arm are movably connected with the beam, the dragging arms on the two sides can move within a certain degree in a relatively-independent mode, in the driving process of an automobile, the deformation degree of the beam is reduced, the beam only bears the axial acting force of the beam, the overall suspension is more flexible, the adaptive capacity of the suspension to complex road surfaces is improved, and the overall comfort degree of the automobile with the semi-independent automobile rear suspension is greatly improved.

Description

Technical field [0001] The present invention relates to the field of vehicle technology, in particular to a semi-independent automobile rear suspension. Background technique [0002] With the development of economy and the progress of society, cars have become an indispensable means of transportation for every family. With the gradual popularity of automobiles, consumers have continuously improved their requirements for the comfort of automobiles. The key factor affecting car comfort is the car's rear suspension system. In order to improve the car's comfort, the car's rear suspension needs to be continuously improved and upgraded to meet consumers' increasing demand for car comfort. [0003] At present, the conventional car rear suspension has two forms: multi-link independent suspension and semi-independent trailing arm suspension. Among them, the semi-independent trailing arm suspension form has been adopted by many automobile manufacturers due to its low cost, simple structure...

AI Technical Summary

Problems solved by technology

Since the left and right trailing arms of the suspension and the transverse torsion beam are fixedly connected by electric welding, and the longitudinal trailing arm and the transverse torsion beam are fixedly connected by electric welding, when the trailing arm moves up and down with the wheel, The transverse torsion beam will limit the swing range of the trailing arm and the torsion beam itself will also be deformed. At the same time, the movement of the trailing arm on one side will affect the movement of the trailing arm on the other side along the torsion beam, making this form of suspension structure impossible. Effectively filter the wheel vibration caused by harsher road conditions, thus greatly reducing the comfort of the car
