Abstract

The invention relates to an automobile brake clearance manual and automatic adjusting arm. The automobile brake clearance manual and automatic adjusting arm comprises a control plate, and the controlplate and a large tooth ring are fixedly connected into a whole; the large tooth ring is in engagement fit with a small gear, and an inner hole of the small gear is of a sector structure; one end of asmall shaft is of a flat square structure; the sector structure of the small gear is connected with the flat square structure of the end of the small shaft; a reset spring is arranged in the gap where the end of the small shaft is matched with the sector structure of the small gear; a one-way bearing sleeves the outer side of the small shaft, and the one-way bearing and a first helical gear are in interference fit and connected into a whole; the first helical gear is in engagement fit with a second helical gear, and the second helical gear sleeves one end of a worm shaft; and the worm shaft is inserted into an inner hole of a worm, the worm is in engagement fit with a worm gear, and an inner hole of the worm gear is connected with a cam shaft of a brake. The automobile brake clearance manual and automatic adjusting arm provided by the invention is reliable and low in cost, the drawing friction problem of a brake is solved, the automobile braking efficiency is improved, and the automobile running safety is improved.

Description

technical field [0001] The invention relates to the technical field of automobile brakes, in particular to a manual automatic adjustment arm for automobile brake clearances. Background technique [0002] At present, the brake clearance adjustment arms on the market are divided into two types: manually adjusted brake clearance adjustment arms, which are hereinafter referred to as "manual adjustment arms" and automatic adjustment brake clearance adjustment arms, which are hereinafter referred to as "self-adjustment arms". Features and defects of the manual adjustable arm: low price, simple structure, uneven product quality, the driver needs to check frequently, and frequent adjustment is required to ensure the brake clearance, and the adjustment process is complicated and requires a certain knowledge of auto repair. If you do not pay attention to check and adjust, the braking force will be too low, resulting in traffic accidents. At present, the self-adjusting arm of the auto...
