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, quadrangular or triangular. Therefore, due to the joint action of alternating stress and high thermal load during high-speed braking, it is easy to cause cracks, falling blocks, and defects in the friction block of the brake pad.

Abstract

The invention discloses a brake pad for a train. The brake pad comprises a mounting plate and friction blocks, wherein, the friction blocks are arranged on the mounting plate; the friction blocks comprise first friction blocks and second friction blocks; the first friction blocks are in a hexagonal shape, and the second friction blocks are in a pentagonal shape; one of five sides of each second friction block, which faces towards the outer side of the mounting plate, is a convex cambered surface; and the second friction blocks are distributed around the front face of the mounting plate and surround the first friction blocks, or the second friction block are distributed in two rows along the inner and outer cambered edges of the front face of the mounting plate and clamps the first friction blocks in the middle. The brake pad has the advantage that damage of the friction blocks of the brake pad under a high-speed and high-pressure brake condition can be effectively reduced.

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, quadrangular or triangular. Therefore, due to the combined effect of alternating stress and high thermal load during high-speed braking, it is easy to cause cracks, falling blocks, and defects in the friction block of the brake pad. Contents of the invention [0003] The object of the present invention is to provide a train brake pad that can effectively reduce the damage of the friction block of the brake pad under high-speed and high-pressure braking conditions. [0004] In order to achieve the above object, the first technical solution of the present invention is: a train brake pad, includin...
