Abstract
A booster clutch includes a pilot-control clutch, a booster output side, a booster input side, a rocker element, a first energy storage element and a drum. The pilot-control clutch has a friction pack and a torque is frictionally transmittable when the friction pack is in a pressed state. The booster output side is torsionally fixed to a pilot-control input side and the booster input side is arranged to be torsionally fixed to an input shaft. The first roller is arranged via a ramp pairing between the rocker element and the booster input or output side. The first energy storage element is arranged between the rocker element and the booster output or input side, or is arranged to transmit a radial force to the rocker element. The first roller applies a predetermined torque over the booster input and output side, and presses the rocker element radially against the drum.
