Booster clutch with a rotational axis for a drive train

A booster clutch having a rotational axis for a drive train, comprising:

• a pilot-control clutch having a friction pack, the friction pack comprising a pilot-control input side and a pilot-control output side, a torque being frictionally transmittable in a pressed state between the pilot-control input side and the pilot-control output side;
• a booster output side which is connected in a torsionally fixed manner to the pilot-control input side;
• a booster input side that can be connected in a torsionally fixed manner to an input shaft;
• at least one rocker element, which is arranged in a torque-transmitting manner in the torque flow between the booster input side and the booster output side;
• at least one roller, which is arranged in a torque-transmitting manner via a ramp pairing between a corresponding one of the rocker elements and the booster input side or the booster output side;
• and
• at least one first energy storage element, the at least one first energy storage element either being:
• arranged in a torque-transmitting manner between a corresponding one of the rocker elements and the booster output side or the booster input side;
• or
• arranged to transmit radial force to the at least one rocker element,
• wherein:
• a drum is also included, and,
• when a predetermined torque is applied over the booster input side and the booster output side as a result of a rolling of the at least one roller on the ramp pairing, the at least one rocker element is pressed radially against the drum.
