DIESEL LOCOMOTIVE ELECTRIC TRANSMISSION Russian patent published in 2012 - IPC B61C15/08 

FIELD: transport.

SUBSTANCE: invention relates to railway transport facilities, particularly, to diesel locomotive electric transmissions. Proposed device consists of traction generator driven by diesel engine and including independent excitation winding and armature. Traction motors are directly connected to traction generator armature, mounted axles engaged with traction motors. Traction generator armature circuit incorporates switching element to respond to control signal generated in the zone of locomotive adhesion limitation and at wheels slippage to inhibit direct connection of motors to generator armature and to allow connection of mounted axles in series with traction motors to generator armature. Electric transmission is provided with control unit to measure motor rpm in response to signals sent by speed transducers connected with motors and to register origination and termination of slippage. Said control unit connects only two slipping mounted axles to traction generator armature by feeding current pulses thereto in turns.

EFFECT: improved traction.
