High-speed high-strength brake pad

Abstract

The invention provides a high-speed high-strength brake pad. A connection plate is additionally arranged behind a steel back, a forked tail plate is arranged on the connection plate, and the connection plate is riveted with the steel back. Welding deformation of the steel back and the forked tail plate is eliminated, the strength of the steel back is reinforced, the steel back cannot deform or shade under effect of braking thrust, and an elastic gasket is installed between the steel back and a framework of the brake pad, so that the brake pad can be firmly adhered with a brake plate for friction braking. By means of the structure, under pushing of the brake pressure, the brake pad can be adhered onto the brake plate on the same plane for braking, and eccentric abrasion and various problems that edges and angles of the brake pad can fall easily, the brake efficiency is low, the brake distance is long and the like caused by the eccentric abrasion are avoided.

Description

technical field [0001] The invention relates to a high-speed train brake device, in particular to a high-speed high-strength 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. ...

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
