Problems solved by technology
[0005] Due to the increasing load capacity of automobiles, the demand for braking force during braking is also increasing, and the brake chamber and brake air pressure have increased. At present, domestic automobiles (especially heavy-duty vehicles) brake Sometimes there will be a backlash phenomenon, causing the brakes to be weak when the car brakes, and the braking distance is too long, resulting in potential safety hazards

The invention discloses a double-insurance locking mechanism regulating arm. The double-insurance locking mechanism regulating arm comprises a shell, a worm, a worm shaft, a controlling and regulating mechanism capable of regulating and limiting worm rotation, a fastening device and a clamping plate which is arranged outside the shell and connected with the shell through the fastening device, and the clamping plate is provided with a groove-shaped regulating mechanism which his used for conducting a screw shaft to regulate rotation by cooperating with tightness of the fastening device. According to the double-insurance locking mechanism regulating arm, the clamping plate is designed outside the shell, rotation of the head of the worm shaft is limited by the clamping plate, the braking clearance is precisely regulated, the fallback phenomenon generated in braking can be reduced, and potential safety hazards are eliminated; the clamping plate and the shell are fixed through a bolt, the structure is simple, installation is convenient, and the self-locking capability is very high.
Description
technical field [0001] The invention belongs to the technical field of automobile adjustment arms, and in particular relates to an adjustment arm of a double safety locking mechanism. Background technique [0002] In the existing automobile braking system, the main function of the automobile adjusting arm is to timely adjust the gap between the brake pad and the brake drum according to the degree of wear of the brake pad to achieve the best braking effect. Not only that, but the adjusting arm is also responsible for the functions of transmitting the braking torque, braking and returning, so it is required to be self-locking during the working process, and it is required to have a long service life. [0003] It is inevitable that the car will vibrate and bump during driving, which often causes the adjustment arm to loosen, thereby affecting the braking effect of the car, and the driver has to adjust the adjustment arm frequently. [0004] There are various styles of anti-loo...
