Problems solved by technology

The deficiencies that this frictional clearance compensator exists are: because this frictional braking clearance compensator adopts motor 5a and driving mechanism 5, drives rotating shaft 2 to rotate to realize the adjustment or compensation of frictional braking clearance, at the same time the shaft end of rotating shaft 2 is provided with manual Wheel 4 is used to meet the locking of the brake wheel when the brake is not running, which not only has a cumbersome structure and increases the cost, but also adjusts the friction braking gap by controlling the number of motor revolutions or controlling the motor operation with a limit switch. Due to the operating inertia and limit of the motor The delay time of the bit switch transmission signal will affect the adjustment or compensation accuracy of the friction brake gap

Abstract

A friction brake gap compensation device relates to a brake. The outer section of the rotating shaft (13) is located in the guide sleeve (12), and there is a manual wheel (14) at the outer shaft end, and the guide sleeve is connected to the hinge shaft of the brake arm on one side of the brake; The nut piece (15) matched with the first threaded section; the guide sleeve has a spring piece (16) for pushing the nut piece into the first threaded section to achieve threaded fit; the diameter of the shaft section (13b) adjacent to one end of the first threaded section It is equal to or smaller than the inner diameter of the first thread segment; the other end of the first thread segment has a limit member (13d) that prevents the axial displacement of the nut; the guide sleeve has a limit block (17) that prevents the nut from rotating ; The second threaded section (13e) at the inner end of the rotating shaft is threadedly connected to one end of the connecting sleeve (18), and the other end of the connecting sleeve is connected to the hinge shaft at the lever inner end of the brake. It has the characteristics of simple structure, easy operation and precise gap compensation.

Description

technical field [0001] The invention relates to a brake, in particular to a gap compensation device between a brake friction plate and a brake wheel (disc) in the brake. Background technique [0002] During the operation of the brake, due to the wear of the friction surface of the brake friction plate and the surface of the brake wheel (or the surface of the brake disc), the friction surface of the brake friction plate and the surface of the brake wheel (or brake disc) will The friction braking gap between the disc surfaces) increases, resulting in the friction surface of the friction plate not being able to effectively fit the brake wheel surface (or the disc surface of the brake disc), causing the braking force to decrease or disappear. In order to ensure the braking effect, it is necessary to adjust or compensate the increased frictional braking clearance due to wear, that is, through the frictional braking clearance compensation device, the increased frictional braking c...
