Abstract
An electromechanical strut is provided for moving a pivotal lift gate 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 lift gate and the motor vehicle body. An extensible shaft is slidably mounted to the housing. The extensible shaft is connected to the other of the lift gate and the motor vehicle body. A drive mechanism includes a rotatable power screw. The 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 lift gate and an extended position corresponding to the open position of the lift gate. A power spring includes one end connected to the extensible shaft and another end connected to the housing for providing a mechanical counterbalance to the weight of the lift gate.
