  • Patent number: 9945168
    Abstract: A friction based counterbalance mechanism for coupling with a closure panel to assist in opening and closing of the closure panel for at least a portion of a path between a fully closed position and a fully open position of the closure panel, the counterbalance mechanism including: an elongate member positioned on a longitudinal axis extending between the proximal and distal ends of the counterbalance mechanism, the elongate member having a peripheral surface, the elongate member having a proximal end for coupling to one of the closure panel and a body of a vehicle; a travel member having a body and at least one friction member mounted on the body, the travel member positioned on the longitudinal axis for reciprocation there along and for providing contact between the at least one friction member and the peripheral surface, said contact for generating a friction force in a first region along the longitudinal axis and in a second region along the longitudinal axis; and a support member coupled to the travel el

  • Patent number: 9776483
    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.

  • Publication number: 20160312514
    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.

  • Patent number: 7938473
    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.

  • Publication number: 20080142327
    Abstract: A novel magnetic friction clutch is disclosed which is capable of relatively high torque transfer for friction discs of a given diameter, compared to prior art magnetic clutches. A friction coating with good magnetic permeability, such as Ferrous Aluminide or the like, is applied to inner and outer annular regions of the three friction discs and increases the frictional coefficient of the discs with little reduction in the clamping force developed through the clutch.
