At least one output disc (5,7), particularly coaxial to the input shaft, has a toroidal inner surface, whereby the input disc and the output disc form a pair. Several friction wheels (18,19) are pivotaboly arranged between the inner surfaces of the at least one pair of input and output discs, for transmission of a torque from the input disc to the output disc. A press device (8) is particularly arranged by the input disc in order to activate it in the direction of the output disc. A gearwheel or an output shaft or similar component is provided, as is an axial flange (2) or similar, on which the output disc supports.
