ANTISKID SYSTEM OF TRAIN AND METHOD OF ANTISKID TRAIN BRAKING Russian patent published in 2019 - IPC B60T13/66 B60T13/36 B60T15/36 

FIELD: machine building.

SUBSTANCE: group of inventions relates to the railway transport. Antiskid system of the train comprises a pneumatic antiskid device, an electric antiskid device and a circuit switching valve. Pneumatic antiskid device is made with possibility to lower braking gas pressure to preset gas pressure to prevent blocking of train wheels. Electric antiskid device is configured to perform antiskid adjustment of braking gas pressure to prevent blocking of train wheels. Valve of the circuit switching has the output end connected to the electric antiskid device or the pneumatic antiskid device on the basis of the working condition of the train. During operation of the electric antiskid device in normal mode, the output end of the circuit switching valve is connected to the electric antiskid device and disconnected from the pneumatic antiskid device. During operation of the electric antiskid device in abnormal mode, the output end of the circuit switching valve is connected to the pneumatic antitheft device and disconnected from the electric antiskid device.

EFFECT: improved operation of the system.
