Mounting method of torsion bar component and torsion bar component mounting structure

Abstract

A mounting method of a torsion bar component is characterized in that a mounting hole corresponding to the torsion bar component is machined in a framework of a bogie; the torsion bar component transversely penetrates through the mounting hole, and the torsion bar component is connected with the mounting hole in the form of interference fit; a stopper used for axially limiting the torsion bar component is arranged in the mounting hole; and the stopper is in contact with the torsion bar component in an abutting manner. According to the mounting method of the torsion bar component, as the torsion bar component is directly mounted on the framework, a supporting seat component in an anti-roll torsion bar system is eliminated, the structure of an anti-roll torsion bar component is simplified, the production cost is reduced, the use reliability of the torsion bar component is not affected in the case of guaranteeing that the supporting seat component is eliminated, the connection between the torsion bar component and the framework is easy to realize, the connecting mode is simpler, the labor intensity of mounting the torsion bar component on the framework can be effectively reduced, and moreover, the space occupancy rate of the a connecting structure between the torsion bar component and the framework is small, and the structural compactness of the connecting structure between the torsion bar component and the framework is high. The invention further provides a torsion bar component mounting structure.

Description

technical field [0001] The invention relates to an installation method of a torsion bar assembly and an installation structure of the torsion bar assembly, belonging to the technical field of anti-rolling torsion bar system installation. 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. The support seat assembly fixed on the frame is connected to the torsion bar shaft in the torsion bar assembly through a layered support ball joi...

Problems solved by technology

[0006] However, for the torsion bar system where the torsion bar axis traverses the frame beam structure, no matter what kind of structure the support seat is, its structure is usually more complicated and the cost is higher
