Abstract
A displaceable system is provided including at least one set of at least two wheels arranged in pairs for movement in a plane, the set being disposed on at least one wheel axle parallel to the plane. A single electric drive motor, a differential having variable torque distribution, and an electric servomotor are provided on the wheel axle for both wheels of a set. The electrical servomotor acts on the differential such that the torque generated by the single electric drive motor is distributed within the wheel axle individually to the wheels.
