Patent number: 10370886Abstract: A swing door actuation system for moving a door about a pivot axis between open closed positions relative to a vehicle body. The system includes a power swing door actuator having a housing connectable to one of the swing door and the vehicle body, an extensible member that moves relative to the housing, and connects to the other of the swing door and the vehicle body, a motor connected to a gear train, and a normally engaged clutch. The motor is operatively connected to a clutch input end through the gear train. The output end is operatively connected to the extensible member. The clutch is disengageable to disconnect the motor from the extensible member. The clutch has a slip torque that is sufficiently high to prevent movement of the door when the door is exposed to less than a selected external torque and the motor is stopped.Type: GrantFiled: February 1, 2017Date of Patent: August 6, 2019Assignee: MAGNA CLOSURES INC.Inventors: Joseph Felix Scheuring, Jube Leonard, Dan Cosmin, Luciano Boin

Patent number: 9776483Abstract: 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.Type: GrantFiled: November 11, 2015Date of Patent: October 3, 2017Assignee: MAGNA CLOSURES INC.Inventors: Borys M. Shchokin, Dan Cosmin, Joseph Scheuring

Patent number: 9174517Abstract: In an aspect, a swing door actuation system is provided for moving a door about a vertical axis between open closed positions relative to a vehicle body. The system includes a housing connectable to one of the swing door and the vehicle body, an extensible member that moves relative to the housing, and connects to the other of the swing door and the vehicle body, a motor connected to a gear train that is non-backdrivable, and a normally engaged clutch. The motor is operatively connected to a clutch input end through the gear train. The output end is operatively connected to the extensible member. The clutch is disengageable to disconnect the motor from the extensible member. The clutch has a slip torque that is sufficiently high to prevent movement of the door when the door is exposed to less than a selected external torque and the motor is stopped.Type: GrantFiled: July 27, 2012Date of Patent: November 3, 2015Assignee: MAGNA CLOSURES INC.Inventors: Joseph Felix Scheuring, Jube Leonard, Dan Cosmin, Luciano Boin

Patent number: 8020683Abstract: 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.Type: GrantFiled: December 13, 2007Date of Patent: September 20, 2011Assignee: Magna Closures Inc.Inventors: M.
