Abstract

The invention discloses a torsion beam. The torsion beam comprises a left cross beam, a right cross beam and a middle connecting beam. A left cross beam matching part is arranged at the right end of the left cross beam. A right cross beam matching part is arranged at the left end of the right cross beam. A left side connecting part and a right side connecting part are arranged on the middle connecting beam. The left side connecting part is connected with the left cross beam matching part, and the right side connecting part is connected with the right cross beam matching part, wherein in the length direction of the torsion beam, the position of the left side connecting part relative to the position of the left cross beam matching part and the position of the right side connecting part relative to the position of the right cross beam matching part can be adjusted. According to the torsion beam, the length of the torsion beam can be adjusted to adapt to vehicles with different wheel tracks, mould reopening for manufacturing torsion beams is not needed, universality is improved, the research and development cost is lowered, and the research and development cycle is shortened.

Description

technical field [0001] The invention relates to a torsion beam, in particular to a torsion beam with adjustable length. Background technique [0002] There is a torsion beam in the vehicle, the torsion beam is arranged between the two wheels of the vehicle along the left and right directions, and the two ends of the torsion beam are respectively connected with the two wheels in the left and right directions, when one of the wheels jumps up and down, the torsion beam will Then it rotates and drives the wheel on the other side to jump accordingly, thereby reducing the inclination and shaking of the entire vehicle body. [0003] In related technologies, the length of the torsion beam is fixed. When the torsion beam is applied to vehicles with different wheelbases, it is necessary to redesign the length of the torsion beam and re-open the mold to manufacture the torsion beam. cost. Contents of the invention [0004] The present invention aims to solve one of the technical pr...
