Abstract: To provide a cam clutch that allows use of the outer race as a rotating member without requiring a complex structure, and that allows a size reduction in the axial direction. The cam clutch includes an operating mode switch mechanism (140) for switching between two or more of a free state that allows relative rotation in both directions, a one-way clutch mode that allows relative rotation in one of forward and reverse directions, and a locked state that prohibits relative rotation in both directions. The operating mode switch mechanism (140) includes a cam orientation changing part (141) axially movable independently of rotation of the inner race (110) and the outer race (120). A plurality of cams (131) include an engaging portion (136) protruding from a side face toward the cam orientation changing part (141).

Abstract: To provide a simple-structured cam clutch that does not require precise control and is operable with a smaller drive force and less prone to damage on cam surfaces or inner and outer raceways. The cam clutch includes a plurality of cams circumferentially arranged between an inner race and an outer race and supported by a cage member, and a selector capable of changing an orientation of the cams. The selector includes a driven part allowing a rotation angle thereof to be controlled relative to the inner race or outer race to which the cage member is fixedly attached, and a selector body circumferentially displaceable relative to the driven part in a resilient manner by a spring-loaded mechanism. The selector body includes a cam orientation control protrusion capable of changing the orientation of the cams by making contact with the cams.

The cam clutch includes a plurality of cams circumferentially arranged between an inner race and an outer race. The cams are arranged in a plurality of rows adjacent each other in a direction of rotation axis. The cam clutch has a selector that allows a rotation angle thereof to be controlled relative to the inner race or the outer race. The selector has a cam orientation control surface capable of changing the orientation of at least one row of cams by making contact with a cam surface. The cam orientation control surface includes a cam release portion radially protruded toward the cams more than a cam actuator portion and moving the cams to a non-operating orientation.

Abstract: An object of the present invention is to provide a cam clutch capable of switching from one operating mode to another and offering improved stability of clutch operations and high responsiveness. The object is achieved by an operating mode switching means (180) having a cam attitude change part (185) being drivable independently of rotation of the inner race (110) and outer race (120). A load support point (Sp) is located radially between a load application point (Ap) of the cam attitude change part (185) on the cam (140) and a distal contact point (Ep) of the cam (140) on a raceway positioned on a radially distal side relative to the load application point (Ap). The radial distance (d1) between the load application point (Ap) and the load support point (Sp) is larger than the radial distance (d2) between the load support point (Sp) and the distal contact point (Ep).
