Control circuit for test system of arm for automatically regulating clearance of brake of automobile

Abstract

The invention provides a control circuit of a test system for an automotive automatic brake clearance adjustment arm, which belongs to the technical field of mechanical-electrical integration. The control circuit resolves the problems of low test accuracy, tedious process and incapability of stimulating test under severe environment. The control circuit of a test system for an automotive automatic brake clearance adjustment arm comprises a data input-output module, a central processing unit, a power supply and a sensor module, wherein the input-output module and the sensor module are all connected with the central processing unit, and the control circuit further comprises a hub driving motor connected with the central processing unit, and a driving air chamber which drives the whole arm to operate. The central processing unit controls the hub driving motor and the automatic adjustment arm air chamber to operate, and the power supply provides power for the whole control circuit. The invention has the advantages of accurate and speedy test, and having the capability of really stimulating actual working condition.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and relates to a control circuit, in particular to a control circuit of a test system for an automatic adjustment arm of an automobile brake gap. Background technique [0002] Automobile braking system is an important part to ensure the personal safety of drivers and passengers when the automobile is running at high speed. The brake gap automatic adjustment arm is a key part of the vehicle braking part. It is used to adjust the brake gap between the brake shoe and the wheel hub to keep it at a constant value to ensure reliable braking and safe driving of the vehicle. Before the automatic brake gap adjustment arm leaves the factory, the brake gap, braking force and torque should be tested and adjusted. [0003] Manufacturers of traditional brake clearance automatic adjustment arms use manual methods for this detection and adjustment, the parameters are relatively vague, it is difficult to ac...

Problems solved by technology

[0003] The traditional brake clearance automatic adjustment arm manufacturers use manual methods for this detection and adjustment, the parameters are relatively vague, it is difficult to achieve detection accuracy, and it is very cumbersome

Or use a dedicated test bench for testing. This test mode not only has poor versatility, low intelligence, and redundant hardware equipment, but also cannot simulate testing in harsh environments at all, and it is difficult to adapt to the diversity of test objects and automation of operations.
