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 housing connected to one of the closure member and the motor vehicle body. An extensible shaft is connected to the other of the closure member and the motor vehicle body for slidable movement relative to the housing. A motor-gear assembly operably drives a rotatable power screw. A drive mechanism converts rotary motion of the power screw into linear motion of the extensible shaft to move the extensible shaft 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. A clutch/coupling assembly is operably disposed between the motor-gear assembly and the power screw and integrates a slip clutch device and a flexible coupling into a common unit.
