Embodiment

[0016] This program is implemented in this way, please refer to figure 1 , this scheme is implemented in this way. When the automobile drum brake needs to adjust the clearance, an adjustment mechanism is needed to adjust the clearance, but the adjustment mechanism is mostly controlled by a hydraulic system. This scheme uses an air control system instead. It has a flexible installation method and can It can effectively save space, avoid on-site environmental pollution, have good equipment operation stability, low failure rate, and is easy to maintain. Switch, after pressing the button, the PLC in the electrical control system 7 will issue instructions to start and control the two-position two-way solenoid valve 9, and the two-position two-way solenoid valve 9 will control the air pressure from the three-way valve 6 to the fast machine head 8, The size of the air pressure determines whether the adjustment mechanism operates, so as to complete the adjustment mechanism to achieve ...

Abstract

The invention discloses a self-clearance adjusting device of a car drum brake. The self-clearance adjusting device comprises an air source (1) and a pressure increasing valve (3). The air source (1) is connected to an inlet of an air storage tank (4) with an air pipe passing through an air source unit (2) and the pressure increasing valve (3). The air storage tank (4) is connected two quick couplings (8) with an air pipe passing through a pressure regulating valve (5) and a three-way valve (6). A two-position two-way solenoid valve (9) is arranged at the position, between the three-way valve (6) and the quick couplings (8), of the air pipe. The two-position two-way solenoid valve (9) is controlled by an electrical control system (7). The self-clearance adjusting device of the car drum brake has the beneficial effects that the structure is simple, practical and convenient to use, production efficiency is high, space is saved, and environmental pollution caused by hydraulic oil leakage is avoided.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automobile drum brake self-gap adjustment device. Background technique [0002] With the development of the economy and the improvement of people's living standards, automobiles have become one of the important means of transportation for people to travel, and the demand for automobiles is also rising. In the process of automobile manufacturing, the power source used by the self-adjusting device of automobile drum brake Most of them use hydraulic system as the power source, and most of them use overall integration. The disadvantages are: the installation takes up space; technical solutions. Contents of the invention [0003] In order to overcome the deficiencies in the prior art mentioned above, the present invention adopts a self-gap adjustment device for automobile drum brakes with the characteristics of simple structure, convenient use, space saving, high producti...
