Abstract

The invention discloses an automatic compensation device of a brake. The automatic compensation device comprises a hinged shaft hinged on a brake lever. A connecting shaft is vertically arranged on the hinged shaft, and is in clearance fit with the hinged shaft. Thread bushings, namely a first thread bushing and a second thread bushing, are arranged respectively on two ends of the connecting shaft. An inner thread matched with a brake pull rod is arranged in the first thread bushing, and a moving ratchet is fixedly sleeved on the end portion of the second thread bushing. A wire thread insert is further arranged on a lever corresponding to the moving ratchet, and a reset spring is arranged in the wire thread insert. A fixed ratchet is sleeved in the wire thread insert. A limiting platform is arranged at the top of the wire thread insert, and is used for preventing the fixed ratchet from falling off from the wire thread insert. The moving ratchet is matched with the fixed ratchet. The automatic compensation device is used for adjusting abrasion gaps formed after friction pieces are abraded, so that the brake can be guaranteed to be kept in a normal operation condition.

Description

technical field [0001] The invention belongs to the field of brakes, and in particular relates to an automatic compensation device for worn brake pads. Background technique [0002] With the continuous development of society, brakes are more and more widely used in various industries and fields, such as metallurgical mines, lifting transportation, coal mining machinery, port horses, petrochemical, engineering machinery, etc.; as a safety component, brakes are important to the entire The field of application is of great significance. [0003] Current brake application status: (1) The reserved travel of the pusher in the brake must be manually adjusted; (2) The brake pad positioning device in the brake must be manually adjusted; (3) The positioning devices of the two arms in the brake must be manually adjusted; ( 4) The brake immediately brakes immediately when the pusher fails, without any buffer; [0004] Specific action principle: a. During the normal use of the brake, th...
