ABSTRACT OF THE DISCLOSURE A double-axle drive for trucks of a railway vehicle has a drive motor with a drive shaft extending parallel to the longi- tudinal axis of the vehicle and a respective gearing mechanism engaged with each end of the drive shaft. Each gearing mechanism is drivingly coupled to a hollow shaft which concentrically sur- rounds a respective wheel-set axle. The wheel-set axle and hol- low shaft are coupled by elastic couplings provided at each end of the hollow shaft. Each elastic coupling includes a coupling half mounted on the hollow shaft and a coupling half axially alig- ned therewith mounted on the axle. One coupling half has a plu- rality of radially extending pins and the other has a plurality of radially extending arms, the pins and arms being positioned alternately in a rotational direction. Elastically yieldable elements are provided between the pins and arms, are initially tensioned, and engage surfaces on the pins and arms which are not parallel to the wheel-set axle.
