Embodiment 1

[0024] 1 and 2 , the manual adjusting arm of the automobile brake clearance of the present invention includes an adjusting arm housing 1 , a worm wheel 6 , a worm 5 , and an adjusting bolt 13 . The worm wheel 6 and the worm 5 are arranged in the adjusting arm housing 1 in a mutually meshing manner, the adjusting bolt 13 is located in the adjusting arm housing 1 and its outer end protrudes outside the adjusting arm housing 1, and the worm 5 is fixedly sleeved in the circumferential direction. Adjust the screw 13. In order to prevent the adjusting bolt 13 from axially shifting in the adjusting arm housing 1, an annular limiting groove 4 is provided on the inner and outer surface of the adjusting bolt 13, and the adjusting arm housing 1 is connected with the limiting groove. The position corresponding to 4 is provided with a limit hole 3 , and the inner end of a limit pin can pass through the limit hole 3 and be inserted into the limit slot 4 with clearance.

Abstract

A manual arm used for regulating gas of brake on automobile consists of regulation arm shell, worm and worm wheel set in said shell and engaged to each other, regulation bolt set in shell and positioning units set between regulation bolt and regulation arm shell as well as used for preventing regulation bolt from rotation relative to regulation arm shell.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an adjusting arm capable of manually adjusting the braking clearance of automobiles. Background technique [0002] When the car is braking, it is generally realized by the friction force generated when the brake shoe and the brake drum are in contact. In the process of driving, there will be frequent contact and friction between the brake shoe and the brake drum. Due to the wear effect, the gap between the brake shoe and the brake drum will become more abrasive, which will affect the driving process of the car. The use safety of the brake mechanism. In order to improve the safety of driving, an automatic adjustment arm or a manual adjustment arm is often provided in the existing automobile braking mechanism. These adjusting arms can make compensatory adjustments to the increased gap between the brake shoe and the brake drum due to wear, so that the brake gap bet...
