Abstract

The invention relates to the field of a buffer wear-resistant pad and discloses a buffer wear-resistant pad for a motor train unit anti-roll torsion bar device as well as a manufacturing method thereof. The buffer wear-resistant pad comprises a buffer wear-resistant pad body (1); the buffer wear-resistant pad body (1) is cylindrical; the buffer wear-resistant pad body (1) comprises a wear-resistant layer (11) and a buffer layer (12); the wear-resistant layer (11) and the buffer layer (12) are fixedly connected; the inner surface of the wear-resistant layer (11) and the outer surface of the buffer layer (12) are positioned on the same curved surface; the common wear-resistant pad has poor buffer effect; the buffer wear-resistant pad adopts a double-layer type structure and comprises the buffer layer and the wear-resistant layer; the buffer wear-resistant pad is designed on each of the two sides of the shaft end part of a torsion bar; the buffer wear-resistant pads are arranged on two half type pillow beam support inner holes; the buffer layer is contacted with a pillow beam end part cover plate; gap between the wear-resistant layer and the shaft end face of the torsion bar is theoretically 1 to 2 mm; and in the operation process, the shaft end part is intermittently contacted with the wear-resistant end face and generates circumferential torsion friction with the surface, and the layered structure has the buffer effect and the surface wear-resistant effect.

Description

technical field [0001] The invention relates to the field of cushioning and wear-resistant pads, in particular to a cushioning and wear-resistant pad for an anti-rolling torsion bar device of an EMU and a manufacturing method thereof. Background technique [0002] Carry out design according to the design process and design method of CRH380A EMU, and develop the anti-roll torsion bar device for export-type EMU. The model of this project is the mainstream model of the overseas EMU project of Sifang Co., Ltd., and the market prospect of subsequent new cars and maintenance is very broad. This type of wear-resistant pad has been used in large quantities in CRH3 models, and most products have entered the third-level repair stage. Ordinary wear-resistant pads have only a wear-resistant effect due to their high hardness, and the cushioning effect is not good. The present invention adopts a double-layer structure, including a buffer layer and a wear-resistant layer, and a buffer wea...
