DEVICE TO INCREASE ADHESION BETWEEN LOCOMOTIVE WHEELS AND RAILS Russian patent published in 2010 - IPC B61C15/00 

FIELD: transport.

SUBSTANCE: invention relates to railroad transport and particularly to device intended for increasing adhesion between locomotive wheels and rails. Wheel pairs with sliding contacts are mechanically coupled with traction motors and electrically isolated from the other elements of car truck to produce, together with rails, short-circuited electric circuit with respect to current source output. Multichannel electric current source features galvanically isolated channels with adjustable output current. Each wheel pair produces, together with rails, short-circuited electric circuit via separate output of multichannel current source, while said current source varies currents in short-circuited circuits of rails and wheels with rpm of locomotive wheels.

EFFECT: higher reliability and safety.
