Testing device and testing method for automatic pressure regulating valve of electric control pneumatic braking system

Abstract

The invention provides a testing device and testing method for an automatic pressure regulating valve of an electric control pneumatic braking system. The testing device comprises an air source, a pneumatic loop, a valve, a sensor, a signal processing unit and a control unit. The automatic pressure regulating valve is subjected to rack testing including function testing, static performance testing, dynamic performance testing, air tightness testing, leakage testing and braking force testing, so that high risk of real vehicle detection is avoided, the testing efficiency is improved, and the testing consistency is guaranteed. According to the invention, the automatic pressure regulating valve is checked before loading; the performance is improved by continuously modifying the parameters of the automatic pressure regulating valve through testing, so that the automatic pressure regulating valve meets the real-time, rapid, independent and accurate requirements required by the commercial vehicle electronic control pneumatic braking system, the braking response time of the commercial vehicle electronic control pneumatic braking system is shortened, and the reliability of the commercial vehicle electronic control pneumatic braking system is improved. Data of the automatic pressure regulating valve are collected and displayed in real time, and operation is convenient; detection processis high in automation degree.

Description

Technical field [0001] The invention belongs to the technical field of motor vehicle braking, and specifically relates to a test device and a test method for an automatic pressure regulating valve of an electronically controlled pneumatic brake system. Background technique [0002] The safety, stability and comfort of commercial vehicles are the focus of the road transportation industry. The pneumatic braking system is the core module that determines the braking performance of commercial vehicles and is one of the most important devices to avoid traffic accidents. In recent years, the electronically controlled pneumatic braking system (EBS, Electronic Braking System) of commercial vehicles at home and abroad has been greatly developed and gradually equipped on commercial vehicles to improve the braking performance and enhance the safety of commercial vehicles. [0003] As the core component of the electronically controlled pneumatic braking system for commercial vehicles, the autom...

Problems solved by technology

If the actual vehicle test is directly used, it will not only be time-consuming and labor-intensive, but also have low efficiency and high risk. Therefore, it is urgent to develop a detection device for automatic pressure regulating valves to ensure that the functions and performance of automatic pressure regulating valves meet the loading requirements.
