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.
