Title:
FRICTION CLUTCH
Document Type and Number:
WIPO Patent Application WO/2018/194078
Kind Code:
A1
Abstract:
A friction clutch (1) equipped with an input member (2), a friction clutch mechanism (7), a first rotating body (21), a back torque limiter mechanism (25), and a second rotating body (23). The friction clutch mechanism (7) has multiple friction plates (8, 11) and a pressure plate (12) that presses these friction plates (8, 11). The back torque limiter mechanism (25) has a cam groove (44) on the first rotating body (21) side, a cam groove (45) on the second rotating body (23) side, and a ball (41) between these cam grooves (44, 45). The cam grooves (44, 45) have a hemispherical mating section (47, 51) and an inclined cam section (48, 52). Due to the movement of the ball (41) from the mating section (47, 51) to the inclined cam section (48, 52) an end portion (61) of the first rotating body (21) pushes the pressure plate (12) in the opposite direction from the friction plates (8, 11).
