Abstract

The invention provides a clearance self-regulating mechanism in an automobile air pressure disc brake, belongs to the technical field of automobiles, and is used for solving the technical problems that the assembly production efficiency is relatively low and the like in the prior art. According to the clearance self-regulating mechanism in the automobile air pressure disc brake, the air pressure disc brake comprises a seat body, a pushing rod and a cam wheel; the mechanism is arranged on the seat body and is positioned between the pushing rod and the cam wheel; the clearance self-regulating mechanism comprises a support and a regulator assembly arranged on the support; the pushing rod penetrates through the support; the regulator assembly is positioned at the side part of the pushing rod;a spiral pipe is sleeved on the pushing rod; the spiral pipe is connected with the pushing rod through screw threads; the outer side surface of the spiral pipe is provided with an annular tooth; the regulator assembly is provided with a transmission gear; the transmission gear is meshed with the annular tooth at the outer side surface of the spiral pipe; the cam wheel is provided with a dial pin;and the regulator assembly can be dialed through the dial pin so as to enable the transmission gear to rotate unidirectionally. The mechanism enables the regulator assembly to form an individual module, and the production and assembly efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an automobile air pressure disc brake, in particular to a gap self-adjusting mechanism in the automobile air pressure disc brake. Background technique [0002] There are two types of brakes for modern commercial vehicles: drum type and disc type. disc brakes. [0003] Simply speaking, car braking is to use friction to convert kinetic energy into heat energy, so that the car loses kinetic energy and stops. Therefore, heat dissipation is very important to the braking system. If the brake system is often in a high temperature state, it will hinder the conversion process of energy, resulting in a decrease in braking performance. The faster the car, the greater the heat generated by braking, and the greater the impact on braking performance. Solving the heat dissipation problem will play a role in improving the braking performance of the car with half the effort. Therefore, in ad...
