A tread brake device for easy wear identification

Abstract

The present invention relates to the technical field of brake systems, in particular to a tread brake device that facilitates wear identification, including a rod base, a push rod driven by a power mechanism and reciprocally slidably connected to the rod base, and a brake shoe assembly. The brake pad assembly includes a mounting seat and a pad body fixed on the mounting seat for contacting with the wheel tread to generate braking friction, the end of the push rod is connected to the mounting seat; the middle part of the outer surface of the mounting seat A first groove is provided, and a second groove corresponding to the first groove is provided in the middle of the inner surface of the pad body. The first groove communicates with the second groove and jointly forms an airtight and used Paint chamber filled with colored paint. The invention is beneficial to reduce the abrasion of the wheel tread and prolong the service life of the wheel. The invention is beneficial to identify the brake pads that will reach the wear limit in the maintenance process, so as to ensure driving safety.

Description

technical field [0001] The invention relates to the technical field of rail vehicle braking systems, in particular to a tread braking device that facilitates wear identification. Background technique [0002] With the development of technology, most of the braking systems of rail vehicles use tread brake structure; the patent CN 206327382 U promptly discloses an electric tread brake for rail vehicles, which includes brake tiles, push heads, Dust cover, casing, power base, driving part, sensor, adjusting rod, limit ring, compensation motor, compensation mechanism, wiring letter, electric control cabinet, brake spring, push rod, power base and driving part are arranged on the machine In the opening of the shell, the front end of the adjustment rod is inserted into the stepped hole of the driving part until it is inserted into the cavity of the power seat, the rear end is connected with the sensor, the rear end of the push rod is inserted into the center hole of the adjustment ...

AI Technical Summary

Problems solved by technology

[0003] In the tread braking structure, the kinetic energy of the rail vehicle is converted into frictional heat energy through the friction between the wheel tread and the brake pads, and finally the purpose of parking is achieved, so the brake pads will be worn; as the number of braking increases, The brake pads will gradually become thinner until they reach the limit of use of the brake pads; at present, the wear detection of the brake pads usually uses an electronic control alarm, such as patent CN204704298U or patent CN207080537U, but the cost is relatively high , it is difficult to promote the application
