The torsion between the sun gear (S) and the wheel (T) is controlled by means of a very flat thread (G) and an electronically controlled and servo-supported axial pressure via the displaceable motor shaft (M). The possible displacement only matches the selected mechanic tolerances according to which the pressure between the wheel (T) and the rollers (R) builds-up. The torque which is controlled by the instantaneous axial pressure is guided to the ring gear (H) (drive shaft) by means of the interaction between the wheel and the rollers and the planet gears (P).
