Vehicle Brake comprehensive performance test rig

[Applicable standards]

QC/T239-1997 < Bus, truck brake performance requirements>; QC/T 479-1999 < Bus, truck brake bench test method>; QC/T556-1999 < Brake temperature measurement and thermocouple installation>; <Commercial vehicle braking performance requirements and test methods of exposure draft.>

[Function]:

Mainly used for passenger cars, trucks, construction vehicles driving with pneumatic drum or disc brake assembly performance, wear test. During braking, the device capable of measuring braking torque, brake pressure change, brake temperature, braking speed, brake chamber pushrod force brake chamber push rod and the displacement of the braking time, braking deceleration speed, braking distance.
