Abstract:
1. A movable system for movement in a plane, the movable system comprising: at least one set of wheels, the at least one set of wheels including a first wheel and a second wheel arranged side-by-side as a pair; at least one wheel axle including a first wheel axle for the first wheel and a second wheel axle for the second wheel, the first wheel axle and the second wheel axle being parallel to the plane, the first wheel being arranged on the first wheel axle, the second wheel being arranged on the second wheel axle, the first wheel and the second wheel being rotatable around at least one axis perpendicular to the first wheel axle, to the first second wheel axle and to the plane; a single electric drive motor; a differential with a variable torque distribution; and an actuator, the drive motor, the differential and the actuator being provided as a drive unit located on the first and second wheel axles, the actuator being separate from the drive motor and acting on the differential in such a way that torques generated by the single electric drive motor are distributable within the first and second wheel axles individually to the first and second wheels; wherein the actuator is an electric motor actuator having a power less than a power of the drive motor.
