ABSTRACT:
A clutch device for controlling transmitted torque in a vehicle comprises a first friction clutch including multiple clutch disks, a hub, a clutch drum and a pressing ring; a second friction clutch including multiple clutch disks, a clutch drum, a cam ring and an electromagnet; a cam mechanism; and a spring. A part of the thrust force is cancelled by energizing force of the spring to shift an operating point of the first friction clutch to a high torque side. A range where only the second friction clutch operates becomes wider. Therefore, change in the torque of the second friction clutch relative to change in operating force is decreased. This contributes to an accurate torque control. In accordance with the function of this clutch device, features of front wheel drive and 4WD vehicles are obtained so that fuel consumption can be decreased and road ability can be improved. Further, straight running performance of a vehicle can be achieved and a tight corner braking phenomenon can be avoided.
