Novel high-speed brake lining

Abstract

The invention provides a novel high-speed brake lining. A connecting board is added on a steel back, a forked tail board is disposed on the connecting board, and the connecting board and the steel back are in a riveted joint. Welding deformation of the steel back and the forked tail board is eliminated, the strength of the steel back is improved so that the steel back is prevented from being deformed or chattered under the action of a pushing force of braking, an elastic pad is installed between the steel back and a framework of a braking block, and the braking block can be effectively and closely attached to a brake disc to perform friction braking. By means of the structure, the braking block can be closely attached to the brake disc on the same plane to perform braking, eccentric wear is avoided, and problems that edges and angles of the braking block are prone to be worn away, the braking efficiency is low, and the braking distance is excessively long due to eccentric wear are solved.

Description

technical field [0001] The invention relates to a high-speed train brake device, in particular to a novel high-speed brake pad. Background technique [0002] High-speed brake pads are a key component in the braking system of high-speed trains. They are mainly composed of multiple brake blocks, steel backs and dovetail plates. During the process, multiple brake blocks of the high-speed brake pads rub against the brake disc of the high-speed train on the same plane to stop the train. However, in the high-speed brake pads widely used in the prior art, spot welding is used for the connection between the dovetail plate and the steel back, that is, several through holes are processed at the position where the bottom of the W-shaped dovetail plate is in contact with the steel back. Spot welds at the holes connect the dovetail plate and steel backing together. The local high temperature generated during the welding process can easily lead to deformation of the steel back. The defo...

AI Technical Summary

Problems solved by technology

The local high temperature generated during the welding process can easily lead to deformation of the steel back. The deformation of the steel back will cause the two brake blocks to not be on the same plane. Although it can be eliminated by subsequent machining, the deformation of the dovetail plate caused by welding cannot be eliminated.

After the high-speed brake pad is installed on the braking device of the high-speed train, the brake block cannot be fully contacted with the brake disc, and the braking performance is unstable and the efficiency is low. Under high speed, high braking energy and high pressure, this The phenomenon is more serious and the safety hazard is huge

At the same time, there will inevitably be pores, cracks, and virtual welds in the welds during welding, which also pose potential safety hazards
