Brake disc with adjustable handbrake clearance hole

Abstract

The invention discloses a brake disc with an adjustable handbrake clearance hole, and particularly relates to the field of brake discs. The brake disc comprises a fixed disc, a connecting disc is fixedly arranged at the center of the fixed disc, a mounting disc is fixedly arranged at the center of the connecting disc in a penetrating mode, a storing disc is fixedly arranged at the center of the mounting disc, a reinforcing disc is fixedly arranged in the connecting disc, a first adjusting groove, a second adjusting groove, an oil groove and a sealing groove are formed in the reinforcing disc,the first adjusting groove, the second adjusting groove and the oil groove are formed in one side of the sealing groove, and the first adjusting groove and the oil groove are formed at interval in thehorizontal direction. According to the brake disc with the adjustable handbrake clearance hole, the handbrake clearance can be adjusted precisely, a elastic sheet makes contact with the inner wall ofthe first adjusting groove so as to remind an operator of the adjusted one-gear distance, a bent elastic sheet makes contact with the inner wall of the second adjusting groove, fine tuning can be conducted on the two-gear distance, and lubricating oil can be added into the oil groove so as to prevent the inner walls of the first adjusting groove and the second adjusting groove from being ground flush due to severe scratching.

Description

technical field [0001] The invention relates to the field of brake discs, and more specifically, the invention relates to a brake disc with adjustable clearance holes for hand brakes. Background technique [0002] The brake disc is a round plate, usually with two arc-shaped or semi-circular brake shoes fixed inside. It also rotates when the car is moving, and the braking force is generated by clamping the brake disc with the brake caliper.
