Abstract
The invention relates to a clutch device for selective transmission of a torque from a first shaft or hub to a second shaft or hub, in particular for a gear-shifting system for a bicycle. The clutch device has first and second clutch halves, an opening device adapted to generate, from an operating torque with which the first clutch half is supplied, in particular by means of the operation of the bicycle with the gear-shifting system, an opening force by means of which the clutch device is opened, as well as an actuating device for controlling the opening device. According to the invention, the opening device is arranged spatially separated from the torque transmission region of the clutch device, i.e., from that spatial region at which, when the clutch device is closed, a torque transmission from the first to the second clutch half may take place. Utilizing the operating torque to generate the opening force for the clutch device facilitates opening the clutch device and thus shifting under load.
