Abstract

The invention discloses a brake adjusting arm which comprises an adjusting arm lever and a gear, wherein the adjusting arm lever is connected with an air chamber push rod, and the gear with a gear ring is connected with a camshaft. The adjusting arm lever is provided with a connecting hole, the gear is connected with the adjusting arm lever capable of rotating around the axis of the connecting hole, the gear is provided with an adjusting arm capable of driving the gear ring to rotate around the axis of the connecting hole, and an adjusting mechanism connected with the adjusting arm lever is arranged on the adjusting arm and can drive the adjusting arm to rotate and return. Relative rotation angles of the adjusting arm lever and the gear are finely adjusted by studs and adjusting bolts, so that the brake clearance of a brake is adjusted conveniently. A return spring can achieve a return function, also fixedly support relative positions of the gear and the adjusting arm lever, and adapt to flexible adjustment and brake.

Description

technical field [0001] The invention relates to a brake system component of an automobile, in particular to a brake adjusting arm for adjusting the brake clearance, and belongs to the technical field of automobile parts. Background technique [0002] The braking of the vehicle is generally realized by the contact and friction between the brake shoe and the brake drum. In the process of driving, the brake shoe and the brake drum will be in frequent contact and friction, so that the friction between the two The gap between the brakes becomes larger, which will affect the safety of the vehicle brake mechanism. At present, the adjustment arm is generally used to adjust the brake brake clearance. At present, most domestic adjustment arms are worm and worm structures. The structure is complex and the processing cost is high, and the adjustment arm will be scrapped after the worm structure fails. [0003] CN201502652 U discloses a vehicle brake adjusting arm, comprising a housing,...
