Abstract (en)
[origin: EP0308616A2] In a driving unit for rail vehicles having a motor gear unit which consists of a motor arranged parallel to the wheel set axle and an end wheel gearing coupled to its drive shaft, the said end wheel gearing having on the output side a hollow shaft concentrically surrounding the wheel set axle, the hollow shaft is connected to the wheel set axle solely via a single elastic coupling which permits axle displacements and axle angle deviations. In addition to the torque transmission, the coupling serves for supporting the motor gear unit. Two further support points are provided for receiving tilting moments and mass acceleration forces on the motor and/or gearing housing so that a 3-point support is present for the unit. The use of the elastic coupling for supporting weight permits a design which is space saving in comparison with known parallel drives.
