Abstract:
A two-way clutch assembly (10) comprising:an inner race (14), an outer race (22) wherein said inner and outer races are supported for rotation about a common axis (A) and wherein said inner and outer races (14, 20) define cam portions (26) between them; an engagement mechanism (22) disposed between said inner and outer races, said engagement mechanism (22) including a cage assembly (30) and a plurality of rollers (32) supported by said cage assembly (30) in spaced annular disposition relative to one another about said axis of rotation (A), said cage assembly (30) including an axially extending splined hub (50), said engagement mechanism (22) operable to shift between a first position providing torque translation between said inner and outer races (14, 20) in one rotational direction while allowing relative freewheeling rotation between said inner and outer races (14, 20) in an opposite rotational direction and a second position providing torque translation and relative freewheeling rotation between said inner and outer races (14, 20) in rotational directions opposite to that provided by said engagement mechanism when disposed in said first position; and an actuator assembly (24) that is operatively connected to said cage assembly (30) and includes an apply plate (52) operatively supported by said splined hub (50) for axial movement relative thereto, said actuator assembly (24) operable to simultaneously move in an axial direction and rotate about said axis of rotation (A) in an indexing manner in response to a biasing force to shift said cage assembly (30) and said plurality of rollers (32) between said first and second positions to selectively provide torque translation and relative freewheeling rotation between said inner and outer races (14, 20) in either rotational direction as said plurality of rollers (32) are selectively moved into and out of engagement with said cam portions (26).
