Anti-roll torsion bar assembly and anti-channeling method thereof

Abstract

The anti-rolling torsion bar assembly includes a torsion bar shaft, a torsion arm fixed at the end of the torsion bar shaft, and a support seat assembly sleeved on the torsion bar shaft. The loose anti-loosening assembly and the anti-movement assembly that prevents the support seat assembly from moving relative to the torsion bar shaft. The arm is fixed. In the present invention, the torsion arm is used as a connector between the anti-loosening component and the anti-movement component. The anti-movement component transmits the lateral movement force of the support seat component to the torsion arm, and the anti-loosening component ensures that the positioning stability of the torsion arm is good, The load-bearing reliability is high, which not only prevents the torsion arm from loosening on the torsion bar shaft, but also prevents the axial movement of the support seat assembly relative to the torsion bar shaft, and the reliability of the movement prevention is higher. The invention also provides an anti-channeling method for the anti-rolling torsion bar assembly.

Description

technical field [0001] The invention relates to an anti-rolling torsion bar assembly and an anti-channeling method thereof, belonging to anti-rolling torsion bar parts of rail vehicles. Background technique [0002] The existing anti-roll torsion bar system for rail transit generally includes three parts: torsion bar assembly, connecting rod assembly and support seat assembly. The torsion bar assembly is fixed on the frame through the support seat assembly, and fixed on the vehicle body through the connecting rod assembly. When a roll occurs between the vehicle body and the frame, the torsion bar assembly prevents the increase of the roll angle of the vehicle body relative to the frame, thereby suppressing the roll of the vehicle and improving the lateral stability of the vehicle. [0003] The support seat assembly fixed on the frame by the torsion bar assembly is connected to the torsion bar shaft in the torsion bar assembly through a layered support ball joint. In order to...

Problems solved by technology

[0008] To sum up, in the prior art, in order to restrict the relative movement between the torsion bar assembly and the support seat assembly, and to prevent the torsion bar assembly from moving laterally relative to the support seat assembly, a restriction is added between the torsion bar shaft and the support seat assembly. Position structure, the limit structure bears too much force and is easy to deform, and its anti-channeling reliability needs to be improved
