Problems solved by technology

This device is not yet able to test the performance of the key component of the hydraulic ABS pressure regulator assembly—the solenoid valve.
[0005] Hydraulic ABS pressure regulator assembly comprehensive performance testing device, the common way to generate braking force at present is to use real automobile braking system, including brake pedal, vacuum booster, etc. On May 5th, a static detection test bench for automobile stability control system was disclosed, which can detect the hydraulic actuator assembly and valve body assembly of the electronic stability control system. The whole device has only one pressure regulation circuit. The liquid medium used in the regulating circuit is brake fluid, so it has the disadvantages of strong cor

Embodiment Construction

[0037] Below is that the present invention is further described in conjunction with accompanying drawing:

[0038] refer to figure 1 , the comprehensive performance detection device of the hydraulic ABS pressure regulator assembly involved in the present invention is controlled by the man-machine interface 11 stored in the industrial computer 10 . The test operator first selects the test items and test wheel cylinders in the man-machine interface 11, and the selected test items and test wheel cylinders are generated by the man-machine interface according to the communication protocol between the upper computer and the lower computer compiled in advance. A command code, through the RS232 serial port The bus is transmitted to the hydraulic ABS solenoid valve drive circuit 20, and the hydraulic ABS solenoid valve drive circuit 20 identifies the code, and controls each component of the comprehensive performance detection device of the hydraulic ABS pressure regulator assembly acco...

Abstract

The invention relates to a combination property detection device of a hydraulic pressure ABS pressure regulator assembly, which mainly comprises an industrial computer (10), a hydraulic pressure ABS electromagnetic valve drive circuit (20), the detected hydraulic pressure ABS pressure regulator assembly (30), a pressure generation device (40), a data collecting system (50), a braking system (60) and an exhaust system (70). The detection device of the hydraulic pressure ABS pressure regulator assembly can detect the characteristic parameters of the pressure regulator assembly and evaluate the result of detection according to a pressure model. The detection device leads the detection of the pressure regulator assembly to be transferred to indoor bench test from outdoor road test, thus improving the economy and safety performance of the detection greatly and being used as the detection equipment of the hydraulic pressure ABS pressure regulator assembly manufacturers.

Description

technical field [0001] The invention relates to a comprehensive performance detection device of a hydraulic ABS pressure regulator assembly, which can be applied to the detection equipment of hydraulic ABS pressure regulator assembly manufacturers and the development process of hydraulic ABS controllers. Background technique [0002] Anti-lock Braking System, referred to as ABS, uses electronic control technology to automatically adjust the braking force to prevent wheel locking and vehicle deviation and sideslip during braking, so as to obtain the best braking effect and improve the performance of the vehicle. active safety performance. [0003] When performing anti-lock braking control on the wheels, the performance of the solenoid valve in the actuator of the ABS system is a very important factor affecting its control accuracy and reliability. Nowadays, the pace of ABS localization is getting faster and faster. To produce high-precision and reliable ABS products, it is n...
