Abstract: A power liftgate drive assembly automatically moves the liftgate of a vehicl e between its open and closed positions. The drive assembly is secured to the vehicle at a position near the top of t he liftgate. The drive assembly includes a motor that drives a sector gear between two positions. A guide rod is secured to the sector ge ar to translate the rotational movement of the sector gear into the pivotal movement of the ligtgate. A slot extends through the sector gear that allows the liftgate to be moved manually. A latch locks the guide rod in position with respect to the sector gear for automated movement whereas the latch releases the guide rod to move in the slot for manual operation.

Abstract: The present application discloses a power actuator that has a motor having a rotatable motor output member and a clutch assembly. A stamped, cup-shape ferromagnetic coil casing has a generally radially extending base wall and an annular side wall extending generally axially from the base wall. An annular ferromagnetic flux intensifying washer is positioned adjacent to the base wall of the coil casing. An annular coil of electroconductive material is disposed within the casing with the side wall extending in surrounding relation with respect to the coil such that the field generated by the coil flows generally radially through the base wall and generally axially through said side wall. A ferromagnetic armature is in sliding relation with the annular coil and movable between an engaged position and a disengaged position.

Abstract: The present application discloses a power actuator for a latch assembly. The power actuator has a motor (70) having a rotatable motor output member (94) and a clutch assembly (50). The clutch assembly has a rotatable clutch outpu t member (48). A stamped, cup-shaped ferromagnetic coil casing (126) has a generally radially extending base wall and an annular side wall extending generally axially from the base wall. An annular ferromagnetic flux intensifying washer (160) is positioned adjacent to the base wall of the coi l casing. An annular coil of electroconductive material is operable to selectively generate a magnetic field. The coil (112-118) is disposed within the casing with the side wall extending in surrounding relation with respect to the coil such that the field generated by the coil flows generally radial ly through the base wall and generally axially through said side wall. A ferromagnetic armature (120) is in sliding relation with the annular coil an d movable between (a) an engaged position wherein the armature couples the mot or output member and the clutch output member together so that energization of the motor rotatably drives the clutch output member and (b) a disengaged position wherein the motor output member and the clutch output member are uncoupled to enable the clutch output member to rotate without resistance fr om the motor. Selective energizing of the coil effects movement of the armature between the engaged and disengaged positions thereof.
