UPGRADED TEST BENCH BY OSIPOV FOR DIAGNOSTICS OF VEHICLE BRAKE Russian patent published in 2015 - IPC B60T17/22 G01L5/28 G01M17/07 

FIELD: machine building.

SUBSTANCE: test bench comprises two supports movable in longitudinal direction and having horizontal contact surface to install the wheels of an axis being tested, a separate drive of movable supports by steel ropes wound onto traction drums, the drums are set on one drive shaft rotating in adjusting bearings by a motor and a variator, ball guides to move the movable supports in longitudinal direction. The test bench also comprises a device signalling the start of the movable supports' travelling, a device to determine the force at a brake pedal and its automatic drive, polymer coating, weight sensors, sensors of travelling start and of force at every support, sensors of wheel angular velocities, the signals from the latter sensors are sent to a computer for processing via an amplifier and an analogue-to-digital converter, a drum with steel rope to return the supports into the initial working position, a platform on which the ball guides of one of the movable supports are set, the platform can move in cross direction by sliding guideways by means of a drive screw gear, and rolling supports for all-wheel drive vehicles.

EFFECT: improved quality of braking parameters measurement to get reliable diagnosis of technical state of the brakes.
