A gas-liquid supercharging device for bench brake test of vehicle
By using a pneumatic hydraulic pump system, high-frequency on/off control is achieved through gas drive and electronically controlled valve groups. This solves the safety hazards of manual pedaling and the problems of low efficiency, high cost, and inconvenient installation of hydraulic oil pump systems, thus realizing efficient and safe brake fluid pressure control.

AI Technical Summary
In existing technologies, manual pedal braking poses safety hazards and has poor consistency. Hydraulic oil pump systems are slow to pressurize and depressurize, inconvenient to frequently start and stop, costly, and inconvenient to move and install.
The system employs a pneumatic hydraulic pump system. The gas drive end is connected to the air source interface, the liquid storage tank is connected to the liquid suction end, the electronically controlled valve group controls the air source input and the brake fluid on/off, and the high-pressure output interface delivers brake fluid to the brake actuator. Combined with a compressed air filter, muffler, air pressure regulator and electronically controlled valve group, high-frequency on/off control is achieved.
It achieves automated operation, eliminates safety hazards, ensures consistent pressure application, significantly accelerates pressurization and depressurization speeds, meets the requirements of high-frequency and high-efficiency on/off control, simplifies equipment structure, reduces cost and size, and facilitates mobile installation and maintenance.
