Brake friction assembly for disk brake

A disc brake and component technology, applied in the parts of the brake, the type of the brake, the brake in the axial direction, etc., can solve the problem of increasing the friction area between the brake disc and the friction plate, the wear of the brake disc and the friction plate, and the increase of the brake. The problem of moving disc and friction plate can achieve the effect of good braking effect, increasing friction area and increasing braking torque.

Abstract

The invention discloses a drag friction component of a disc brake, the disc brake and the drag friction component of a clutch used in a winch crane and a cargo vehicle, in particular to the drag friction component which is suitable for being used in high speed or heavy-load devices. The drag friction component comprises a retarding disc and a friction plate. The retarding disc is provided with a ring-shaped drag friction platform. The end surface of the friction plate is provided with a ring-shaped drag friction groove. A braking cylinder rod drives a braking caliper to press the ring-shaped drag friction groove arranged on the end surface of the friction plate on the ring-shaped drag friction platform arranged on the end surface of the retarding disc. The crown surface of the two sides of the ring-shaped drag friction groove arranged on the end surface of the friction plate is contacted with the crown surface of the two sides of the ring-shaped drag friction platform for friction braking. The drag friction component has the advantages of simple and practical structure, convenient maintenance, good braking effect and effectively reducing the size of the friction disc and the manufacture cost.

Description

technical field [0001] The invention relates to a disc brake friction assembly, which is used for the disc brakes and clutches of winches and trucks, and is especially suitable for the brake friction assembly in high-speed or heavy-duty equipment. Background technique [0002] At present, the disc brake adopts the brake disc and the end surface friction braking method of the friction plate. In this braking mode, the friction area between the brake disc and the friction plate is limited when the size of the brake disc is fixed. In order to improve the high speed or heavy load The braking effect of the equipment generally adopts the following methods; one is to increase the size of the brake disc and friction plate to increase the friction area between the brake disc and the friction plate; the other is to increase the loading device and / or add more loading Device and / or increase the number of brakes to achieve the purpose of safe braking, so that the structure of the equipmen...
