Abstract

The invention provides a tool used for replacing a side roll resistance torsion bar bushing block of a bogie and a replacement method. The tool comprises a matrix, wherein the matrix is provided with a mounting hole used to be sheathed to a side roll resistance torsion bar bushing block in a penetrating mode along the horizontal direction; the surface of the matrix is provided with a long trough hole; the length direction of the long through hole is parallel with the center shaft of the mounting hole; the bottom of the long through hole is communicated with the mounting hole; the inside of the long through hole is fixedly provided with two side top blocks; in the long through hole, a main top block is arranged between the two side top blocks; on the matrix, a screw is in spiro union to one side of the main top block, which is opposite to a supporting convex part; and the tail end of the screw is supported on the main top block. According to the tool disclosed by the invention, the surface of the end shaft of the side roll resistance torsion bar of the bogie is free from being damaged when the side roll resistance torsion bar bushing block of the bogie is replaced, the side roll resistance torsion bar of the bogie can be reused after the bushing block is replaced, and the vehicle overhauling cost is lowered.

Description

technical field [0001] The embodiment of the present invention relates to the manufacturing technology of railway vehicles, and in particular to a tooling for replacing a bogie anti-rolling torsion bar bushing and a replacement method. Background technique [0002] As the speed of the train continues to increase, most passenger cars are equipped with an anti-roll torsion bar device between the bogie and the car body. resulting in lateral roll force. [0003] On the end shaft at the end of the anti-roll torsion bar, a cylindrical bushing is fixedly sleeved to prevent the end shaft of the torsion bar from being worn out during the running of the train for a period of time. [0004] After running for 1.2 million kilometers, the passenger car must return to the factory for three-level maintenance. During the three-stage maintenance of the bogie, it was found that the bushings on the end shaft of the anti-roll torsion bar were worn to varying degrees, and new bushes had to be r...
