Abstract
Two clutches are disposed between a driving shaft and a driven shaft, in particular a first synchronous clutch which automatically engages when the driven shaft overtakes the driving shaft and a second synchronous clutch which automatically engages when the driving shaft overtakes the driven shaft. As long as there is no external intervention the two clutches mutually protect one another against unintentional engagement. The clutch arrangement can only be put into a ready or enabled position by the action of an external force. From the ready position, the paired synchronous clutches can effect a torque transmitting connection between a driving shaft and a driven shaft when their rotational speeds are synchronous.
