Anti-side-rolling torsion bar assembly and anti-moving method thereof

Abstract

An anti-side-rolling torsion bar assembly comprises a torsion bar shaft, a torsion arm fixed to the end of the torsion bar shaft and a supporting base assembly arranged on the torsion bar shaft in a sleeving mode, and is characterized by further comprising an anti-loosening assembly used for preventing the torsion arm from loosening on the torsion bar shaft and an anti-moving assembly used for preventing the supporting base assembly from moving relative to the torsion bar shaft. The anti-loosening assembly is installed on the torsion arm, and the anti-moving assembly is in axial positioning fit with the supporting base assembly and is fixed to the torsion arm. The torsion arm serves as a connecting piece of the anti-loosening assembly and the anti-moving assembly, the anti-moving assemblytransmits transverse moving force of the supporting base assembly to the torsion arm, the anti-loosening assembly ensures that the torsion arm is good in positioning stability and high in force bearing reliability, loosening of the torsion arm on the torsion bar shaft is prevented, and the supporting base assembly is prevented from axially moving relative to the torsion bar shaft, so that the anti-moving reliability is higher. The invention further provides an anti-moving method of the anti-side-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
