DEVICE FOR AUTOMATIC TERMINATION OF SLIDING AND SKIDDING OF ROLLING STOCK MOTORED WHEEL UNITS Russian patent published in 2012 - IPC B60L3/10 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to automatic protection of motored wheel units of rolling stock against sliding and skidding. Proposed device comprises pickups of current parameters of motored wheel units including automatic circuit actuators connected with traction motors and nozzle for feeding sand to motored wheel units, computing unit with its inputs connected with parameter transducer outputs and its outputs connected with inputs of aforesaid actuators. Computing unit incorporates motored wheel unit rpm counter, reference rpm generator and comparators with their first input connected with output of reference rpm generator, while second inputs of comparators are connected with outputs of rpm computing units of every motored wheel unit. Inputs of reference rpm generator are connected with outputs of rpm computing unit of every motored wheel unit while outputs of comparators are connected with inputs of aforesaid actuators.

EFFECT: faster operation and higher reliability.
