U-shaped variable cross-section rear torsion beam assembly

Abstract

The invention discloses a U-shaped variable cross-section rear torsion beam assembly of the technical field of automobiles. A left longitudinal arm is installed at the bottom of a left casing pipe, aleft wheel hub plate is installed at the bottom of the left longitudinal arm, a left damper support is installed at the bottom of the right side of the left longitudinal arm, a left spring plate is installed at the top of the left damper support, the left side of the left spring plate is connected with the left longitudinal arm, a torsion beam is installed on the right side of the left longitudinal arm, the top of the left spring plate is connected with the bottom of the torsion beam, a right longitudinal arm is installed at the right end of the torsion beam, a right casing pipe is installed at the top of right longitudinal arm, a right wheel hub plate is installed at the bottom of the right longitudinal arm, and a right damper support is installed at the bottom of the left side of the right longitudinal arm. The U-shaped variable cross-section rear torsion beam assembly has strong rigidity, can satisfy functional requirements of targets well, has a simple forming process and light weight, increases advantages of the torsion beam, and guarantees stability of a roll center.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a U-shaped variable cross-section rear torsion beam assembly. Background technique [0002] At present, the existing automobile torsion beams are generally V-shaped beams and closed beams. The V-shaped beam needs to add a stabilizer bar to ensure the torsional rigidity, and the weight is relatively heavy; the closed beam is difficult to form and the cost is high. Therefore, we propose a U-shaped variable section rear torsion beam assembly. Contents of the invention [0003] The purpose of the present invention is to provide a U-shaped cross-section rear torsion beam assembly to solve the problem that the V-shaped beam proposed in the above background technology needs to add a stabilizer bar to ensure the torsional rigidity, and the weight is relatively heavy; the forming of the closed beam is relatively difficult and costly. high question. [0004] In order to achieve the...
