Detection device for combination property of hydraulic ABS pressure regulator assembly

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...

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 corrosion, high cost and poor performance.

Moreover, although the tester stepped on the brake pedal during the test to simulate the actual vehicle situation more realistically, the test operator was prone to fatigue and poor repeatability.

[0006] At present, when the detection device of the hydraulic ABS pressure regulator assembly detects the pressure regulation characteristics of the pressure regulator, due to the different test conditions such as initial pressure and pressure regulation time, the results obtained under different working conditions are generally different. The common test method The test results can only be expressed quantitatively in the form of numbers, and cannot be evaluated qualitatively because there is no unified standard
