ABSTRACT:
An improved drive for driving the axles of an electric rail car wherein the drive includes an electric motor having a stator and a rotor arranged between the axles of the rail car and transmissions each arranged at an end of the shaft of the rotor and each including a pinion member for coupling energy from its respective rotor shaft end to a drive axle, and wherein the improvement comprises: planetary drives each arranged to couple torque from an end of the rotor shaft to the pinion of the transmission associated therewith; each planetary drive including: a sun gear formed by a geared section at the end of the rotor shaft, three planetary gears arranged in a stationary planet carrier and disposed so as to be driven by said sun gear; a hollow gear arranged to be driven by said three planetary gears and a curved gear coupling arranged between said hollow gear and the shaft of the pinion for transmitting torque thereto.
