Embodiment 1

[0025] A test device for an automobile braking system, including a test bench main body, a control system, a measurement system and a drive system, the hardware of the control system, measurement system and drive system are all assembled on the test bench main body, and testers will press The test program designed on demand is input into the control system through the host computer, and the pedal brake pedal is used to give the test input. The control system sends control instructions to the drive system according to the program, and collects and processes the measured data from the measurement system, and then controls The system generates test curves from the processed test results and feeds them back to the test personnel.

[0026] Such as image 3 As shown, the main body of the test bench is composed of an aluminum alloy frame to form a square frame, on which a host computer and a car seat are mounted, and brakes are respectively installed at the bottom four corners of the...

Abstract

The invention discloses a test device for an automobile brake system. The invention belongs to the technical field of test devices. The test device comprises a test bench body, a control system, a measuring system and a driving system. Hardware of the control system, hardware of the measuring system and hardware of the driving system are all assembled on the test bench body. A tester inputs a testprogram designed as required into the control system through an upper computer and a brake plate is pressed down to provide a test input; the control system sends a control instruction to the drivingsystem according to a program, collects and processes actual measurement data from the measuring system, and then generates a test curve according to a processed test result and feeds back the test curve to the tester. The movable design is adopted, and arrangement is convenient; the installation space of the brake is large, and the measurement requirements of most passenger vehicle brake systemscan be met; the arrangement form of the pipelines and the on-off of each pipeline can be changed by utilizing the electromagnetic valves, and various actual working conditions can be simulated.

Description

technical field [0001] The invention belongs to the technical field of testing devices, and in particular relates to a testing device for an automobile braking system. Background technique [0002] The brake system is an important part of the car chassis, and the overall test of the brake system is generally carried out on the test sample car. The pursuit of higher product quality and research and development efficiency has promoted the creation of brake system test benches. At present, domestic braking system test benches have different forms and levels. [0003] In the current test control system, the test program is relatively fixed and needs to be pre-set, and the test personnel cannot freely design and change the test plan. At the same time, once the layout of the brake pipeline is determined, it cannot be changed and cannot adapt to all test conditions. Moreover, there is no operating seat, so the test personnel cannot personally experience the feedback effect of the...
