Running gear for a rail vehicle with a transversally decoupling motor suspension

A running gear for a rail vehicle, comprising

• a wheel unit,
• a motor unit and
• a running gear frame unit;
• said running gear frame unit defining a longitudinal direction, a transverse direction and a height direction, and being supported on said wheel unit;
• said motor unit being connected to said wheel unit to drive said wheel unit;
• said motor unit being suspended to said running gear frame unit via a connecting device;
• wherein
• said connecting device is transversally elastic to allow, from a transversally undeflected state of said connecting device, a relative transverse motion in said transverse direction between said motor unit and said running gear frame unit;
• said connecting device having a transverse rigidity in said transverse direction, said transverse rigidity, in said transversally undeflected state, being sufficiently low such that, compared to a substantially transversally rigid mounting of said motor unit to said running gear frame unit, a contribution of said motor unit to an inertial moment of said running gear frame unit about said height direction is reduced by at least 50%.
