Problems solved by technology

There is almost no intelligent monitoring system in the existing braking system, which cannot monitor various status parameters of the braking system in real time, and cannot quickly diagnose and predict possible braking failures
[0008] The above discussion shows the problems existing in the current braking system. These problems will cause severe noise pollution during the braking process of the train, harm the physical and mental health of passengers and residents along the way, and greatly shorten the service life of the brake pads, and may even Cause braking accidents, reduce train operating efficiency and economic benefits

Embodiment 1

[0055] A high-speed train braking system that integrates interface and loading optimization and fault monitoring, including a brake disc 1, a brake pad structure and a loading device, the loading device is connected to the brake pad structure, and the brake pad structure is connected to the brake pad structure The brake disc 1 cooperates, and the brake pad structure includes a brake pad back plate 2, and several friction particles 7 are arranged on the brake pad back plate 2, and the several friction particles 7 adopt several kinds of surfaces grooming. The several surface modifications described above include opening holes, chamfering or ditching on the surface of the friction particles 7 . In this embodiment, friction particles 7 with two surface modifications, chamfered and open, are used. In this embodiment, the structure of the brake pad back plate 2 is left-right symmetrical, and its shape is arc-like, and it is stamped and formed by steel material.

[0056] Such as ...

Embodiment 2

[0065] The technical solution of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0066] Such as Figure 4 As shown, in the present embodiment, the number of friction particles 7 is ten, and four of them are porous friction particles 701. Non-porous friction particles 702, the shape of the non-porous friction particles 702 is triangular and only the surface is modified by chamfering. The four porous friction particles 701 are located at the cutting end of the brake pad back plate 2 (ie, the end facing the cutting direction), and the six non-porous friction particles 702 are located at the middle of the brake pad back plate 2 .

[0067] The intelligent monitoring system added to the brake system can also collect the temperature rise change signal of the contact interface between the friction particles 7 and the brake disc 1 . A temperature sensor is arranged on the brake pad back plate 2, and is used to collect the temperature rise chan...

Abstract

The invention belongs to the technical field of friction braking, in particular to a high-speed train braking system integrating interface and loading optimization and fault monitoring. In the braking system in the prior art, the surface decoration of the friction particles on the brake pad is single, the stress concentration exists in the braking process, and the heat distribution of the braking interface is uneven, and the fault checking function is added to the braking system. The technical scheme of the present invention is as follows: the idea of ​​combining different surface modifications on friction particles is proposed, and the advantages of various surface modifications are comprehensively utilized; the installation direction of the friction particles is optimized; the loading device is optimized; an intelligent monitoring system is added to the braking system to conduct fault online monitor. The invention organically combines the advantages of friction particles with different surface modification combinations to realize the reliability, safety and comfort of the braking of high-speed trains; by monitoring various parameters of the braking system in real time, the health of the braking system can be predicted. and problems.

Description

technical field [0001] The invention belongs to the technical field of friction braking, and in particular relates to a high-speed train braking system for fusion interface and loading optimization and fault monitoring. Background technique [0002] High-speed trains usually use a disc brake system. The brake disc is installed on the axle or on the side of the wheel web, and the two brake pads made of synthetic materials are pressed against the side of the brake disc with a brake caliper. A braking force is generated to stop the train from moving forward. This kind of braking method can greatly reduce the thermal load and mechanical wear of the wheel tread because the active force is not on the wheel tread. In addition, the disc brake has a large friction area, stable braking and good braking effect. With the rapid development of the national economy, the operating speed of high-speed trains is increasing day by day, constantly breaking through the maximum operating speed,...
