LOCOMOTIVE TRACTION DRIVE WITH PROPSHAFT Russian patent published in 2014 - IPC B61C9/38 

FIELD: transport.

SUBSTANCE: invention relates to railroad transport and can be used as traction drive for locomotives with motors, including induction motors, at higher speeds. Locomotive traction drive with propshaft with two joint planes comprises two articulated shaft couplings to transfer torque by hollow gear shaft interconnected by the shaft fitted inside gear shaft. First hinge plane is composed by coupling with barrel-like rim and outer rim to compensate for angular and axial shift. Barrel-like rim with outer rim of the first hinge plane is arranged inside hollow gear shaft. Second hinge plane is composed by second coupling with barrel-like rim engaged with coupling outer rim fitted on traction motor shaft to compensate for angular displacement with elastic thrust-sealing elements confining the shaft axial shift and articulated shaft couplings.

EFFECT: simplified propshaft design and assembly, higher reliability.
