Abstract:
1. An electromechanical strut for moving a pivotal lift gate between an open position and a closed position relative to a motor vehicle body, the electromechanical strut comprising: a housing connected to one of the lift gate and the motor vehicle body; an extensible shaft slidably mounted to the housing, the extensible shaft connected to the other of the lift gate and the motor vehicle body; a drive mechanism including a rotatable power screw, the drive mechanism converting 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; and a power spring having 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.
