Abstract
The invention relates to a coupling device for a drive train of a motorcycle or other motor vehicle, in particular for suppressing a so-called hopping. According to the invention, the coupling device has an output rotation part, a switchable friction coupling, which has an energy storage device for closing thereof and which is closed in an unactuated state, and at least one freewheel coupling for forming a torque transmission path for torque transmission from the input rotating part to the output rotating part, wherein the freewheel coupling includes the following components: an inner rotating element, the outer circumference of which forms a sawtooth-shaped circumferential structure having a plurality of circumferentially extending ramps; a substantially annular plate structure having an individual plate element or a stack of a plurality of plate elements, the inner circumference of which forms a sawtooth-shaped circumferential structure having a plurality of circumferentially extending counter-ramps to form an interlock and/or a friction lock together with the ramps of the inner rotating element in a rotation direction; and an outer rotating element surrounding the plate structure. The invention further relates to a corresponding drive train having such a coupling device.
