Abstract
A drive unit for a rail vehicle has a motor-gearing unit which is supported on at least one wheel-set axle of a bogie and which includes either a motor which extends in the longitudinal direction of the vehicle and has miter gearing units connected to both ends of a motor which extends parallel to the wheel-set axle and has a spur gearing unit coupled with its drive shaft. Each miter gearing unit or the spur gearing has as its output a hollow shaft which concentrically surrounds the respective wheel-set axle. The hollow shaft is connected to the associated wheel-set axle by an elastic coupling which permits axle dislocations and shaft-angle deviations, and also by an elastic bearing which transmits the weight of the motor-gearing unit to the axle. The elastic bearing can be provided laterally of the gearing unit on the hollow shaft, or can be provided within the hollow shaft. For countering tilting moment and mass-acceleration forces, at least one lever is provided as a support member and is elastically hinged to the motor and to the vehicle frame or the bogie.
