Automobile torsion beam structure and preparation method thereof

Abstract

The invention provides an automobile torsion beam structure and a preparation method thereof, and belongs to the technical field of vehicle parts. When an automobile turns, acting force borne by the automobile torsion beam structure in the first direction of the automobile can be transmitted to a cross beam through two longitudinal beams in the automobile torsion beam structure; the cross sectionarea of the middle of a beam pipe cavity is smaller than the cross section areas of the two ends of the beam pipe cavity, and the cross section area of the middle of the beam pipe wall is smaller thanthe cross section areas of the two ends of the beam pipe wall; the middle of the cross beam slightly protrudes relative to the two ends of the cross beam in the vertical direction; and due to the special cross beam section and position design, the motion characteristic of an automobile rear suspension is guaranteed, and therefore the stability of rear wheels is guaranteed when an automobile turns.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle parts, in particular to an automobile torsion beam structure and a preparation method thereof. Background technique [0002] The torsion beam structure is one of the key components of the car chassis. The torsion beam structure of the car mainly plays the role of transmitting force to balance the up and down jump of the wheels, reduce the shaking of the car, and ensure the stable driving of the car. [0003] In the related art, the torsion beam structure of an automobile usually includes a crossbeam and two longitudinal beams. The middle parts of the two longitudinal beams are respectively connected to the two ends of the crossbeam. One end is connected to the bearing of the rear wheel. [0004] After the torsion beam structure of the car is installed in the car, the two ends of the longitudinal beam are usually not at the same height, so that the torsion beam structure of the car can be...

AI Technical Summary

Problems solved by technology

However, such a torsion beam structure will cause the rear wheels to receive a greater force from the torsion beam structure along the length of the car, resulting in a greater impact and force from the longitudinal beam on the rear wheels, which will affect the rotation of the rear wheels when the car turns
