DEVICE FOR DIAGNOSTIC THE PNEUMOHYDRAULIC BRAKING DRIVE OF A VEHICLE Russian patent published in 1994 - IPC

FIELD: technical diagnostics of vehicles. SUBSTANCE: device for diagnosing the pneumohydraulic braking drive has a braking machine, two air-pressure pickups and displacement transducer of the pneumohydraulic actuator pistons connected to an electronic device. The diagnostic device secures the supervision of the air pressure in the pneumatic part of the drive, the automatic bringing into operation of the operating control of the braking drive in a set tempo, the processing of information coming from the transducers in the form of analog signals during the specified period of time of the transient process when the braking drive operates, the determination of the diagnostic parameter value, the recognition of the technical state of the braking drive, the determination of a possible fault, the display of the results of measurements and logical transformations. EFFECT: enhanced accuracy of diagnostics. 2 dwg
