High-strength steel punch forming reel pipe torsion beam

Abstract

The invention discloses a high-strength steel punch forming reel pipe torsion beam, and the torsion beam comprises a torsion beam body; the torsion beam body comprises a reel pipe and three middle strips; the middle strips are integrally arranged on the inner side wall of the reel pipe, end blocks are welded to the two ends of the torsion beam body, and the cross section of each end block is in a right triangle shape. A longitudinal arm and a connecting plate are welded to the two ends of the torsion beam. According to the high-strength steel punch forming reel pipe torsion beam, the mode that the middle strip is integrally arranged on the inner side wall of the hollow reel pipe is adopted, the structural strength is improved, breakage is not prone to occurring, and the weight of the whole torsion beam is reduced; the end blocks with the right-triangle-shaped cross sections are welded to the two ends of the torsion beam, the structural strength of the two ends of the torsion beam is improved, the area of the connecting positions of the two ends of the torsion beam and an automobile is increased, the connecting positions are prevented from being broken, the whole torsion beam is in a curve shape with the two thickened ends, and the structural strength is high.

Description

technical field [0001] The invention belongs to the technical field of torsion beams, and in particular relates to a high-strength steel stamping and forming coiled tube torsion beam. Background technique [0002] Torsion beam suspension is a type of rear suspension of automobiles. It uses a torsion beam to balance the up and down jump of the left and right wheels to reduce the shaking of the vehicle and keep the vehicle stable. It belongs to a type of non-independent suspension, also known as It is a semi-independent suspension, and its working principle is to install the non-independent suspension wheels on both ends of a torsion beam. When one wheel jumps up and down, the torsion beam will jump around the two red lines, thereby driving the other side of the wheel to jump accordingly. , to reduce the tilt or shake of the whole body. Because it has a certain torsional stiffness, it can play the same role as the lateral stabilizer bar, which can increase the roll stiffness ...

AI Technical Summary

Problems solved by technology

[0003] The traditional torsion beam is a solid metal connecting rod, which is heavy, which increases the overall weight of the car and affects the flexibility of the car, and the torsion beam has low structural strength and is easy to break and damage
