Embodiment 1

[0043] A brake pad is described, such as figure 1 and Figure 4 As shown, it includes a friction block 2 and a brake back plate 3 that are arranged corresponding to each other. The brake back plate 3 is provided with an elastic support 4 that applies a biasing force toward the friction block 2 away from the brake back plate 3, and is arranged on the friction The protection pad 1 between the block 2 and the elastic support 4, and the hardness of the protection pad 1 is greater than that of the elastic support 4. A protective pad made of heat-resistant stainless steel whose hardness is greater than that of the elastic support is set between the friction body of the brake pad and the elastic support, so that the protective friction block will not float up and down or rotate in a small range during the braking process. Grooves are formed by being squeezed by the elastic support, causing the friction block and the brake disc to be unable to fully fit, affecting the braking perfor...

Embodiment 2

[0047] A brake pad is described, such as figure 1 and Figure 4 As shown, it includes a friction block 2 and a brake back plate 3 that are arranged corresponding to each other. The brake back plate 3 is provided with an elastic support 4 that applies a biasing force toward the friction block 2 away from the brake back plate 3, and is arranged on the friction The protection pad 1 between the block 2 and the elastic support 4, and the hardness of the protection pad 1 is greater than that of the elastic support 4.

[0048] In this example, if figure 1 The friction block 2 shown includes a friction body 5, a connection part 6 arranged on the friction body 5 for connecting the brake pad back plate 3, and a friction body back plate 7 arranged on the lower surface of the friction body 5; the connection part 6 It includes a connection end 10 fixedly connected to the lower surface of the friction body 5 , and a connecting rod 11 inserted into the brake pad back plate 3 and connecte...

Embodiment 3

[0052] A brake pad is described, such as Figure 5 and Figure 4 As shown, it includes a friction block 2 and a brake back plate 3 that are arranged corresponding to each other. The brake back plate 3 is provided with an elastic support 4 that applies a biasing force toward the friction block 2 away from the brake back plate 3, and is arranged on the friction The protection pad 1 between the block 2 and the elastic support 4, and the hardness of the protection pad 1 is greater than that of the elastic support 4.

[0053] In this example, if Figure 5 The friction block 2 shown includes a friction body 5, a connection part 6 arranged on the friction body 5 for connecting the brake pad back plate 3, and a friction body back plate 7 arranged on the lower surface of the friction body 5; the connection part 6 It includes a connection end 10 fixedly connected to the lower surface of the friction body 5 , and a connecting rod 11 inserted into the brake pad back plate 3 and connecte...

Abstract

A friction body protection pad of a brake pad and a brake pad, the protection pad is arranged between the friction block of the brake pad and the brake pad back plate, and is arranged on the brake pad back plate and faces The friction block exerts a bias force away from the back plate of the brake pad and is correspondingly arranged; the hardness of the protection pad is not less than the hardness of the elastic support, which solves the problem of the back plate of the friction block of the existing brake pad. Under the high-frequency force, wear and deformation occur, which affects the braking performance and service life of the brake pads.

Description

technical field [0001] The invention relates to the technical field of brake devices, in particular to a friction body protection pad for a brake pad and a brake pad. Background technique [0002] At present, the braking of high-speed trains mainly relies on the mutual friction between brake pads and brake discs. As the speed of the train continues to increase, the braking load is increasing, and the requirements for the braking performance of the brake pads are also getting higher and higher. Because there is a small position or angle deviation between the brake disc and the brake pad, the friction block on the brake pad is allowed to rotate slightly and the inclination angle changes when the brake pad is braking, so that the friction block and the brake disc The effective friction area between them is increased, the eccentric wear of the friction blocks is reduced, and the braking performance and service life of the brake pads are improved.
