<p>An apparatus for transmitting power from a driving side to a driven side, having a fluid joint means and a rolling bearing clutch (CL) in parallel, the power being transmittable via said fluid joint means and/or said clutch (CL), wherein said clutch (CL) includes an inner and an outer ring (58, 59) having track surfaces (58a, 59a) of hyperboloidal contour, and a plurality of rollers (60) interposed between the outer periphery of said inner ring (58) and the inner periphery of said outer ring (59) at an inclination to the center axis of said rings (58, 59), said clutch (CL) being operated by moving the track surfaces (58a, 59a) near to each other with thrusting means or away from each other, so that when said rings (58, 59) are relatively rotated in one direction, said clutch (CL) is held locked, while it is freely rotatable in the opposite direction. For transmitting power without slip loss, said rings (58, 59) are locked by a thrust while being relatively rotated opposite to the locking direction, said rings (58, 59) becoming freely rotatable by releasing said thrusting means, whereby said clutch (CL) is held in the OFF position.</p> |
