A connecting system which includes a pilot clutch brought into an engaged state by an actuator, a cam member operated by an engaging force of the pilot clutch, an urging member driven and moved by the cam member, and a main clutch brought into an engaged state by a movement of the urging member. The cam member includes a first cam ring restrained by the pilot clutch, a second cam ring provided on the urging member, and rolling members interposed the first and second cam rings for converting the relative rotation of the cam rings into a thrust. The system further includes a biasing member for biasing the urging member and the first cam ring in a direction of abutment against each other in order to generate a frictional force between the urging member and the first cam ring. Thus, it is possible to prevent the engaging force of the main clutch from being influenced by a drag torque produced in the pilot clutch.
A connecting system comprising a pilot clutch brought into an engaged state by an actuator, a cam means operated by an engaging force of the pilot clutch, an urging member driven and moved by the cam means, and a main clutch brought into an engaged state by a movement of the urging member, said cam means being comprised of a first cam ring restrained by the pilot clutch, a second cam ring provided on the urging member, and a rolling member interposed between the first and second cam rings for converting a relative rotation of both the cam rings into a thrust, said system further including a biasing means for biasing said urging member and said first cam ring toward an abutment against each other in order to generate a frictional force between said urging member and said first cam ring by said abutment, and means for providing a dead zone in an operation of said cam means.
