Abstract

The invention relates to a brake pad with three grades of adjusting mechanisms. The brake pad comprises a rigid plate; the three grades of adjusting mechanisms are arranged on the rigid plate; a recess part and a connecting hole are arranged on the rigid plate; the first-grade adjusting mechanism is a connecting block; the connecting block is provided with a smooth projection part; a cylindrical through hole is formed in the center of the projection part; a smooth concave surface is upwards recessed in the lower surface of the connecting block; the connecting block is in clearance fit positioning with a positioning hole in the surface of the rigid plate through a dowel pin; an arch top is arranged at the upper part of the second-grade adjusting mechanism, and a connecting boss is arranged at the lower part; the third-grade adjusting mechanism is a butterfly spring; limiting holes of friction blocks are formed in the rigid plate; the friction blocks are limited by the lower ends of connecting rods after penetrating through the cylindrical through hole and the limiting holes in sequence through clearance fit with the connecting rods; the contact surfaces of the friction blocks and the projection part are matched in shapes; and multiple friction blocks are distributed on the rigid plate. The brake pad can be correspondingly adjusted by different angles; and each friction block can be adjusted on one plane.

Description

technical field [0001] The invention relates to the technical field of brake structure design, in particular to a brake pad with a three-stage adjustment mechanism, which is especially suitable for high-speed rail braking, and can also be extended to the technical field of structural design of other vehicles. Background technique [0002] With the rapid development of my country's high-speed railway, higher requirements are put forward for the safety performance of train operation. The brake pads used in trains generally adopt a fixed connection structure or an elastic connection structure, which cannot adjust the brake pads at different scales, does not have good adaptive performance, and does not have good adaptive performance of the brake pads During high-speed braking, the friction area between the brake pad and the brake disc cannot obtain the maximum effective fit. When the speed exceeds a certain value, if the brake pad cannot be adjusted to ensure the fit area, the b...
