The invention relates to an automatic brake clearance adjustment mechanism assembly. According to the technical scheme, the automatic brake clearance adjustment mechanism assembly comprises a cam-shaped pressure arm structure for transmitting brake power and a supporting seat, the two sides of the pressure arm structure are provided with a master rotary adjustment shaft and a slave rotary adjustment shaft respectively; adjusting screws each provided with one protruding end are arranged in the master rotary adjustment shaft and the slave rotary adjustment shaft respectively; a return spring is fixed to the supporting seat, and the exposed ends of the adjusting screws are provided with brake push plates of a left-right integrated structure; and the side face of a pressure arm is provided with a poking pin. The automatic brake clearance adjustment mechanism assembly is characterized in that the other end, opposite to the end with the adjustment screw, of the master rotary adjustment shaft is provided with a one-way rotating mechanism, and the one-way rotating mechanism comprises an external adjusting sleeve, a middle one-way bearing and an internal rotating ring; and an outer ring of the one-way bearing is in interference fit with the adjusting sleeve, an inner ring of the one-way bearing is in interference fit with the rotating ring, and the end, with the one-way rotating mechanism, of the master rotary adjustment shaft is a smooth circular shaft with a ladder, and a lining is pressed in the rotating ring.
Description
technical field [0001] The invention relates to a brake gap automatic adjustment mechanism assembly, which belongs to the field of vehicle brakes. Background technique [0002] When the brake leaves the factory, the gap between the brake block and the brake disc is preset. After the brake disc is completely braked by the brake block, the pressure arm pin moves within the range of the gap of the adjustment sleeve. However, when the gap between the brake pad and the brake disc becomes larger due to friction loss between the brake pad and the brake disc, the brake pad needs to continue to move toward the brake pad after running through the preset gap during braking. When the moving plate touches, the pressure arm pin will move the adjustment sleeve, the adjustment sleeve drives the one-way bearing to rotate together, and through the one-way bearing drives the inner sleeve and the rectangular torsion spring to rotate together, and the torque is transmitted to the friction sleeve...
