Problems solved by technology

The self-adjusting mechanism is composed of a support seat assembly, an active adjustment mechanism and a driven adjustment mechanism. The main and slave adjustment mechanisms need to be connected by a chain. The mechanism is relatively complicated, and the two push plates in front of the two adjustment mechanisms are likely to cause unequal high
[0003] Due to the existence of the brake gap self-adjusting mechanism, after the friction lining is worn to a certain extent, the distance between the brake disc and the push plate is too small when replacing the friction lining, so the friction lining cannot be put in. At this time, it is necessary to put the wrench in the active adjustment mechanism There are problems such as inconvenient operation to manually adjust the gap on the
[0004] Because the air chamber of the traditional air disc brake is directly in contact with the pressure arm in the brake caliper body, the installation position of the air chamber can only be in a fixed position, which is not flexible enough

Embodiment

[0016] Embodiment: the invention provides a kind of technical scheme: as Figure 1-2 As shown, the disc brake includes a brake caliper body 1 composed of a housing and a bridge. The two are connected by four hexagon socket bolts, which reduces the difficulty of casting. There is an adjustment in the installation cavity of the housing. The mechanism is composed of a clutch assembly and a manual adjustment mechanism; the opening part of the caliper body has a pressure plate, a friction plate, and a brake disc; the outside of the caliper body is equipped with an adjustment arm, an air chamber bracket, and an air chamber.

[0017] When the air chamber on the air chamber bracket works, it will push the air chamber push rod and then push the adjustment arm to make it rotate; since the adjustment arm is connected with the adjustment shaft through the inner spline, the adjustment shaft will rotate with the rotation of the adjustment arm; the adjustment shaft When rotating, the clutch ...

Abstract

The invention provides a novel air pressure disc brake, and relates to the technical field of brakes. A vertical combined bracket is adopted, so that the casting difficulty is lower; a clutch structure is adopted, so that internal installation is simpler and more convenient; a manual adjustment gear is arranged, and operation is flexible; and an adjusting arm is adopted for pushing, and air chamber installation can be adjusted according to a push rod.

Description

technical field [0001] The invention relates to the field of brakes, in particular to an air pressure disc brake. Background technique [0002] Traditional disc brakes use a self-adjusting mechanism with two five-tooth sleeves to adjust the brake clearance. The self-adjusting mechanism is composed of a support seat assembly, an active adjustment mechanism and a driven adjustment mechanism. The main and slave adjustment mechanisms need to be connected by a chain. The mechanism is relatively complicated, and the two push plates in front of the two adjustment mechanisms are likely to cause unequal high. [0003] Due to the existence of the brake gap self-adjusting mechanism, after the friction lining is worn to a certain extent, the distance between the brake disc and the push plate is too small when replacing the friction lining, so the friction lining cannot be put in. At this time, it is necessary to put the wrench in the active adjustment mechanism There are problems such...
