Description

[0002] A locomotive refers to a self-propelled vehicle that pulls or pushes railway vehicles and does not carry any operating load. The anti-roll torsion bar in a locomotive is a device that uses a metal elastic rod to produce torsional deformation when subjected to torque to provide a torsional counter-torque. The reliability of the torsion bar device has an important impact on the operating quality and safety of the vehicle. The anti-roll torsion bar device is mainly assembled from a torsion bar shaft, a torsion arm mounting seat assembly, a connecting rod assembly and other components to connect the car body and the bogie. The torsion bar assembly is fixed to the frame through the mounting seat assembly and fixed to the car body through the connecting rod assembly.

Due to the influence of the environment, foreign matter and dust are easily accumulated on the mounting seats. When the torsion bar moves relative to the mounting seats, these foreign matter and dust will be squeezed with the intersection of the torsion bar and the mounting seats. When working for a long time, it is easy to cause wear to the torsion bar and the mounting seats, reducing the service life of the anti-roll torsion bar and its mounting seat. Utility Model Content
