PNEUMATIC CIRCUIT OF TRAILER BRAKES WITH DETERMINATION OF SHUTDOWN AND ITS METHOD Russian patent published in 2021 - IPC B60T13/00 

FIELD: car industry.

SUBSTANCE: method for the determination of leakage in a pneumatic circuit of trailer brakes is proposed. The method includes the provision of a controller, a main valve, the first sensor, the second sensor, a leakage control valve with an electromagnet, a working environment source of a pneumatic system, the first brake output and the second brake output. The method additionally includes the supply of the first pressure to an inlet of the main valve and output of the second pressure from an outlet of the main valve. The first pressure is determined by means of the first sensor, and the second pressure is determined by means of the second sensor. The method also includes the transmission of determined first pressure and second pressure to the controller and the comparison of the difference between the first pressure and the second pressure with a threshold value. If the difference meets the threshold value, leakage in the pneumatic circuit of trailer brakes is determined. A trailer brake system and a pneumatic trailer brake system are also proposed.

EFFECT: control of the pneumatic circuit is achieved.
