Problems solved by technology

Brake pads for trains generally use a rivet-fixed brake pad structure, and the shape of the friction block is generally circular, hexagonal, quadrilateral or triangular. The effective friction area between the brake discs is about 90%, and it is difficult to achieve 100% fit. On the one hand, the brake pads are easily caused by the joint action of alternating stress and high thermal load during high-speed braking, and the friction blocks of the brake pads are easily caused. Cracks, falling blocks, defects and other phenomena; on the other hand, the surface of the brake disc is prone to high temperature points, resulting in thermal stress concentration and thermal cracks, which affect the braking force efficiency of high-speed EMUs

[0046] The edge of the brake pads adopts the first friction block 3' of the pentagonal body with the middle hole 3-5, and the second friction block 3" of the pentagonal body with the middle hole 3-5 has an arc surface, and the circle The arc surface faces the outside of the mounting plate 1, and the arc surface can effectively reduce the damage of the friction block of the brake pad under high-speed and high-pressure braking conditions.

[0047] The components of the brake pads are connected by elastic contact and floating, especially the end of the connecting shaft at the tail is elastically connected with the mounting plate through a spring collar, which can reduce noise and play a certain role in shock absorption.

[0048] like Figure 13 , 14 As shown, it is the second embodiment of the present invention, wherein, the second friction block 3 "is distributed into two rows along the inner and outer arc edges of the front of the mounting plate 1 and sandwiches the first fric...

Abstract

The invention discloses a train brake lining with an adjuster, comprising an installation plate, an adjuster, friction blocks and a spring retainer ring, wherein the adjuster comprise an installation lug boss and an adjuster positioning convex pin, a tail connection shaft for the friction blocks passes through a through hole on the adjuster and a friction block installation hole on the installation plate, and the end part of the tail connection shaft is elastically connected with the installation plate through the spring retainer ring; in the friction blocks, first friction blocks are hexagon bodies, second friction bodies are pentagon bodies, one face of five side faces of each second friction block, facing the outside of the installation plate, is a cambered face, the second friction blocks are arranged along the periphery of the front side of the installation plate and surround the first friction blocks in the middle, or the second friction blocks are distributed along the inner and outer arc edges of the front side of the installation plate in two rows and sandwich the first friction blocks. The train brake lining with the adjuster can improve an effective friction area during working and effectively decrease the occurrence of the phenomena of cracking, falling, defecting, performance declination and the like of the friction blocks, and has strong heat dissipation capability.

Description

technical field [0001] The invention relates to a train brake device, in particular to a train brake pad. Background technique [0002] With the trend of high-speed development of trains, higher requirements are put forward for train braking. Brake pads for trains generally use a rivet-fixed brake pad structure, and the shape of the friction block is generally circular, hexagonal, quadrilateral or triangular. The effective friction area between the brake discs is about 90%, and it is difficult to achieve 100% fit. On the one hand, the brake pads are likely to cause the friction block of the brake pads due to the combined action of alternating stress and high thermal load during high-speed braking. On the other hand, the surface of the brake disc is prone to high temperature points, resulting in thermal stress concentration and thermal cracks, which affect the braking force efficiency of high-speed EMUs. Contents of the invention [0003] The purpose of the present invent...
