ABSTRACT:
An actuator for selectively causing axial compression of friction elements in a clutch is disclosed. The actuator comprises a pair of beveled wedge washers and a bearing race supported between the washers. The race supports conical bearing rollers in a generally radial orientation. An actuator plate is mounted for rotation relative to the bearing race and includes bearing ramp surfaces that are operable to move the conical bearing rollers radially inwardly thereby forcing the washers to move apart axially and to thereby cause compression of and torque transfer through the friction elements. A clutch including the actuator is well suited for inclusion in a transfer case.
