Abstract: An electromechanical strut is provided for moving a pivotal closure member between an open position and a closed position relative to a motor vehicle body. The electromechanical strut includes a drive mechanism having a motor-gearbox assembly that is operable to drive a rotatable power screw. The drive mechanism converts rotary motion of the power screw into linear motion of an extensible member to move the extensible member between a retracted position corresponding to the closed position of the closure member and an extended position corresponding to the open position of the closure member. The motor-gearbox assembly includes a gearbox unit equipped with a dual-stage planetary geartrain that is operably disposed between a motor output and the power screw. The dual-stage planetary geartrain includes a first stage gearset and a second stage gearset sharing a common ring gear.

Abstract: An electromechanical strut is provided for moving a pivotal closure member between open and closed positions relative to a motor vehicle body. The electromechanical strut includes a drive mechanism having a motor-gearbox assembly, flex coupling assembly, and a spring-loaded supplemental friction assembly that are operable to drive a rotatable power screw. The drive mechanism converts rotary motion of the power screw into linear motion of an extensible member to move the extensible member between a retracted position corresponding to the closure member closed position and an extended position corresponding to the closure member open position. The motor-gearbox assembly includes a motor and a geartrain having an output component driven at a reduced speed relative to the motor speed. The flex coupling assembly is operably disposed between the output component and the power screw. The spring-loaded supplemental friction assembly generates and applies a supplemental frictional force to the flex coupling assembly.

Abstract: The present disclosure generally relates to a two-door closure system for a motor vehicle including a body having an A-pillar and a C-pillar being spaced from one another. According to an aspect of the disclosure, the closure system includes a front door having a front edge that is pivotably connected to the A-pillar. The closure system also includes a rear door that has a rearward edge that is pivotably coupled to the C-pillar of the vehicle body. At least one swivel hinge unit is provided that has a first pivot pin that is pivotably connected to the rearward edge of the rear door, and a second pivot pin for being pivotably connected to the C-pillar of the vehicle body to allow the rear door to initially pivot and translate away from the front door prior to pivoting the rear door between an open and closed position about the second pivot pin.

Abstract: An electromechanical strut and method of moving a closure member of a vehicle between an open position and a closed position is provided. The electromechanical strut includes a power drive unit including a motor, a leadscrew, a planetary gearset operably connecting the motor to the leadscrew, and an electromechanical brake assembly. The electromechanical strut further includes a telescoping unit including an extensible tube and a drive nut for converting rotary motion of the leadscrew into linear motion of the telescoping unit. The electromechanical brake assembly is selectively moveable between an engaged state, wherein the leadscrew is prevented from rotating to prevent relative axial movement between the power drive unit and the telescoping unit, and a disengaged state, wherein the leadscrew is permitted to rotate to allow relative axial movement between the power drive unit and the telescoping unit.

Abstract: An electromechanical strut for moving a closure member between open and closed positions relative to a vehicle body includes a housing having an inner surface bounding a cavity extending along a central axis between opposite first and second ends. A power screw is disposed in the cavity in operable communication with a motor, with a gear assembly operably connecting the motor to the power screw. An extensible member has an outer cover tube received in the housing cavity and a drive mechanism for converting rotary motion of the power screw into linear motion of the extensible member. An annular gap extends between the inner surface of the housing and an outer surface of the outer cover tube. An annular bushing is disposed within the annular gap to minimize laterally play between the housing and the outer cover tube.
