China Automobile Braking System Test Bench

Automobile braking system test bench
1. Function Introduction (double-chamber or three-chamber test)
This test bench is used mainly for testing performance of air compressor, master valve, air chamber, quick release valve and four-circuit valve in brake system of high, medium and low models automobiles at home and abroad and carrying out double-chamber or three-chamber test of master valve. As test equipment of automobile maintenance, it is especially applicable for maintaining and testing city bus and other all vehicles using air brake.
The time required by air compressor to reach specified pressure value when air compressor runs at rated RPM.
Master valve: The required time of inflating air from main tank into air chamber through master valve (the time through air);
Air chamber: After air is inflated from main tank into air chamber to reach set pressure value, hold the pressure.
Quick release valve: After air is inflated from main tank into sub-tank through quick release valve to reach set pressure value, hold the pressure.
Four-circuit valve: The same with test of quick release valve.
