Claim:
1. A clutch, comprising a first clutch part connected to a drive shaft; a second clutch part connected to an output shaft; a pressure element arranged to engage the first and second clutch parts, wherein a reinforcement mechanism is provided in a force flow zone between the pressure element and the second clutch part, wherein the mechanism includes first and second ramps to transmit a biasing force for pressing the pressure element against the first clutch part, wherein the first and second ramps contact to form a first ramp pair wherein a circumferential direction component of the first and second ramps of the first ramp pair points in a first circumferential direction, and third and fourth ramps are pressed against each other to form a second ramp pair wherein a circumferential direction component of the third and fourth ramps of the second ramp pair points in a second circumferential direction opposite the first circumferential direction, and wherein the first and second ramps are arranged pressing against each other and the third and fourth ramps are pressing against each other such that the first and second ramps and the third and fourth ramps, respectively, remain in surface contact when a direction of torque, transmitted between the first and second clutch parts, changes from the first circumferential direction to the second circumferential direction.
