[0002] High-speed train braking is achieved by frictional brake discs of high-speed brake pads. Most of the existing high-speed brake pads adopt welding or riveting structures. Insufficient contact between the brake pads of high-speed brake pads and the surface of the brake disc is common, resulting in high-speed brake pads. The eccentric wear phenomenon of the brake block is prominent, and the edges and corners are prone to drop around the friction block, resulting in a large amount of wear, which leads to insufficient smooth braking of high-speed trains and long braking distances

Embodiment Construction
[0025] With reference to the accompanying drawings, the high-speed brake pad with elastic structure disclosed by the present invention is composed of a steel back 1, a brake block 2, a dovetail plate 3, a washer 4, a disc spring 5, a guide sleeve 6, a bush 7, and a rivet 8. After the processing of each part and the sintering of the brake block 2 are completed, the riveting work of each part is carried out first, specifically: the rivet 8 is passed through the rivet hole on the steel back 1, and then a gasket 4 is set on the rivet 8 , and then the guide sleeve 6 is installed between the rivet 8 and the two disc springs 5, and the two disc springs 5 are as image 3 The way shown is set back to back outside the guide sleeve 6, then insert another washer 4, then insert the brake block 2 into the rivet 8 through its rivet hole, and finally set the bushing 7 on the inside of the guide sleeve 6 on the outside of the rivet 8.
[0026] The first function of the bush 7 is to ensure tha...

The invention provides an elastic high-speed brake lining, consisting of a steel backing (1), a brake block (2), a dovetail plate (3), a gasket (4), a disk spring (5), a guide sleeve (6), a bushing (7) and a rivet (8). The elastic structure high-speed brake lining provided by the invention has the advantages of high mechanical strength, small wearing capacity, stable friction performance, good thermal stability, good heat conductive performance, high dynamic moment and static moment, no noise, seawater corrosion resistance, sand wind prevention, excellent salt mist resistance and the like. Due to the elastic structure, the brake block of the high-speed brake lining is protected from eccentric wear caused by insufficient contact of the brake block of the high-speed brake lining and the surface of a brake disc, so that a high-speed train can brake smoothly, and the braking distance is short.
Description
technical field [0001] The invention relates to a brake device for a high-speed train, in particular to a high-speed brake pad with an elastic structure. Background technique [0002] High-speed train braking is achieved by frictional brake discs of high-speed brake pads. Most of the existing high-speed brake pads adopt welding or riveting structures. Insufficient contact between the brake pads of high-speed brake pads and the surface of the brake disc is common, resulting in high-speed brake pads. The eccentric wear phenomenon of the brake block is prominent, and the edges and corners are prone to drop around the friction block, resulting in a large amount of wear, which leads to insufficient smooth braking of high-speed trains and long braking distances. Contents of the invention [0003] technical problem to be solved [0004] In order to solve the above problems, the present invention provides a high-speed brake pad with an elastic structure.
