FRICTION CLUTCH DEVICE

WIPO Patent Application WO/2020/008507

A1

A clutch device (1) for controlling transmission of torque between a first rotating body (21) and a second rotating body (23) each capable of rotating about an axis is provided with: a cam plate (35) provided with a first cam surface (35c) and capable of rotating about the axis with respect to the second rotating body (23); a pilot clutch (29) linked to the cam plate (35) so as to brake the cam plate (35) in the circumferential direction with respect to the first rotating body (21); a pressure plate (39) which is provided with a second cam surface (39c) facing the first cam surface (35c) in the axial direction and can rotate together with the second rotating body (23) and move in the axial direction; a plurality of rolling bodies (41) for rolling in accordance with differential motion of the cam plate (35) with respect to the pressure plate (39), the rolling bodies (41) being interposed between the cam plate (35) and the pressure plate (39); a support (37) which forms a ring about the axis and rotatably supports each of the plurality of rolling bodies (41) and restricts rolling thereof, the support (37) being friction-fitted with the second rotating body (23) so as to generate resistance against movement in the rotation direction; and a friction clutch (25) for transmitting torque between the first rotating body (21) and the second rotating body (23) when axially pressed to the pressure plate (39).
