Abstract
A double clutch structure for connecting an input shaft to an output shaft while always maintaining a predetermined driving torque therebetween includes first and second clutches adapted to selectively connect the input shaft to the output shaft. An engaging structure is movable in a first direction to engage the first clutch and disengage said second clutch. The engaging structure is movable in a second direction to disengage the first clutch and engage the second clutch. A first Belleville spring reacts between the engagement structure and the first clutch for applying a clutch engaging pressure to the first clutch when the engagement structure is moved in the first direction. Similarly, a second Belleville spring reacts between the engagement structure and the second clutch for applying a clutch engaging pressure to the second clutch when the engagement structure is moved in the second direction. The first and second Belleville springs always apply a predetermined minimum clutch engaging pressure to at least one of the first and second clutches such that a predetermined driving torque is always maintained between the input shaft and the output shaft.
