Abstract
The hub (14) of the positive axial clutch has its outer surface (16) defined as a hyperboloid. Inclined thrust transmitting cylindrical rollers (26) in the space (22) between the outer surface (16) and a similarly shaped inner surface (20) of an outer annular member (18) only transmit drive in one direction of rotation of the axially fixed clutch members (14,18). Alternatively, the rollers (26) are located in grooves (34) in one surface and by axially moving one member by a cam (X), drive is transmitted in both directions of rotation when the rollers contact ramp surfaces (36) edging the grooves.
