Abstract:
A running gear for a rail vehicle, including a wheel unit, a motor unit and a running gear frame unit being supported on the wheel unit. The motor unit is connected to the wheel unit to drive the wheel unit. Further more, the motor unit is suspended to the running gear frame unit via a connecting device. The connecting device is transversally elastic to allow a relative transverse motion between the motor unit and the running gear frame unit. The connecting device has a transverse rigidity being sufficiently low such that a contribution of the motor unit to an inertial moment of the running gear frame unit about the height direction is reduced by at least 50%.
