FIELD: the inventions refer to measuring technique and may be used for diagnosing of apparatus of pneumatic breaking drive of brakes of autotransport vehicles, and also for checking of pneumatic apparatus used in other fields of technique.
SUBSTANCE: at realization of this mode a sign-variable effort is applied to the level of a regulator of breaking forces. The level is displaced from one extreme position to the other. Through a tap of feeding of working body to the input of the regulator of breaking forces pressure is fed, at input and output pressure is measured with the aid of sensors, an angle of turning of the level of the regulator of breaking forces is measured with the aid of a sensor of an angle turning. The measured parameters are transmitted to a computer to register the position of the level of the regulator of breaking forces. Malfunction of the regular of breaking forces is defined according dependence of pressure at the output of the regulator of breaking forces from the angle of the turning of the level of the regulator of breaking forces. The arrangement has measuring manometers, received and accumulated receivers, regulators of pressure, connecting hoses, a tap of feeding of a working body, a computer with an analog-digital converter, a block of converters, a time relay, sensors of input and output pressure, a breaking chamber, a pneumatic valve. It has also a electromechanical arrangement which is connected with the aid of a pendulum and a rod with the level of the regulator of breaking forces. On its axle there is a sensor of the angle turning connected with the block of converters. Besides the arrangement is provided with a controlling device and which is connected with the electromechanical arrangement, the electromagnetic valve, the analog-digital converter and the time relay.
EFFECT: increases safety of movement of autotransport vehicles in the process of breaking.
