Abstract

The invention relates to a wheel brake braking force adjustment device, which includes a first housing, a hollow sleeve, a second housing, a power mechanism and a braking mechanism, both sides of the first housing are fixedly connected with the hollow sleeve, and the first The top of the housing is fixedly connected with the second housing, and the upper part of the two side walls of the second housing is provided with through holes. The power mechanism is installed in the second housing, and the power mechanism cooperates with the second housing. There is a brake mechanism, and the brake mechanism cooperates with the power mechanism. The present invention cooperates with the power mechanism and the brake mechanism, so that the contact area during braking can be increased, thereby prolonging the service life, and the brake pad can be adjusted conveniently through the brake mechanism; under the action of the elastic force of the first return spring, the The rotating shaft moves backward for reset, so it is not necessary to reset the rotating shaft separately, thereby reducing the workload.

Description

technical field [0001] The invention relates to an adjusting device, in particular to a wheel brake braking force adjusting device. Background technique [0002] Drum brakes use the brake transmission mechanism to make the brake shoe press the brake friction plate against the inner side of the brake drum, thereby generating braking force, decelerating the wheel or stopping within the shortest distance as required to ensure driving safety, and Ensure that the car is parked reliably and cannot slide automatically. [0003] The effective braking capacity of the wheel is the guarantee that the vehicle can run safely. The existing wheel braking force adjustment arm is composed of a worm gear inside. The worm gear is driven to rotate by rotating the worm gear, and the worm gear drives the brake rotating shaft to realize the adjustment of the braking force. [0004] Since the contact surface between the worm gear and worm is only linear contact, the contact area of ​​this contact ...
