Embodiment Construction

[0030] Combine below Figure 1 to Figure 5 Embodiments of the present invention are described in detail.

[0031] The installation method of the torsion bar assembly is characterized in that the installation hole 11 corresponding to the torsion bar assembly 2 is processed on the frame 1 of the bogie, the torsion bar assembly 2 is traversed in the installation hole 11 and the torsion bar assembly 2 is installed with the torsion bar assembly. The holes 11 are connected by interference fit, and a stop 12 for axially limiting the torsion bar assembly 2 is provided in the installation hole 11 , and the stop 12 is in close contact with the torsion bar assembly 2 .

[0032] Such as figure 1 As shown, the installation hole 11 corresponding to the torsion bar assembly 2 is processed on the frame 1 of the bogie, and the torsion bar assembly 2 and the installation hole 11 are connected by interference fit, that is, the torsion bar assembly 2 is directly installed on the frame, saving T...

Abstract

The installation method of the torsion bar assembly is characterized in that the installation hole corresponding to the torsion bar assembly is processed on the frame of the bogie, the torsion bar assembly is crossed in the installation hole, and the torsion bar assembly and the installation hole are connected by interference fit A stopper for axially limiting the torsion bar assembly is arranged in the installation hole, and the stopper is in close contact with the torsion bar assembly. The present invention installs the torsion bar assembly directly on the frame, saves the supporting seat assembly in the anti-rolling torsion bar system, simplifies the structure of the anti-rolling torsion bar assembly, reduces its production cost, and ensures that the support seat assembly is omitted The use reliability of the torsion bar assembly is not affected, the connection between the torsion bar assembly and the frame is easy to realize, and the connection method is simpler, which not only can effectively reduce the labor intensity of installing the torsion bar assembly on the frame, but also the torsion bar assembly and the frame The space occupation rate of the connecting structure is small, and the structure is highly compact. The invention also provides a torsion bar assembly installation 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...
