Abstract:
A power closure actuator especially suitable for use in powering various automotive closure devices. The actuator includes a brushless pancake electric motor having an output shaft; a sun gear on the output shaft; a plurality of compound planet gears each having a large diameter lower portion meshingly engaging the sun gear and a small diameter upper portion; a ring gear surrounding and meshingly engaging the small diameter upper portions of the planet gears, and a cable drum splined to the ring gear. A mounting plate positioned in overlying confronting relation to the flat upper face of the motor mounts a plurality of planet shafts extending upwardly from the mounting plate in circumferentially spaced relation to the motor output shaft with one of the compound planet gears journaled on each planet shaft.
Abstract:
A sliding wall-mounted interior door system that includes a telescoping door actuating mechanism that is attached to the upper portion of the door, and a roller assembly that extends horizontally from the wall and engages a track in the lower portion of the door. The door actuating system is designed so that the movement of one of the door panels simultaneously moves the other door panel in the opposite direction. The actuating mechanism is designed so that a gearing assembly within the actuating mechanism moves laterally when the door system is moved between the open and closed positions.
Abstract:
A spindle drive for a movable component includes a threaded spindle which is rotatable about a spindle axis; a spindle nut which engages the threaded spindle; and a transmission element which can be connected to the movable component, the transmission element being fixed against rotation about the spindle axis and being axially drivable by rotation of the spindle nut. An intermediate element, which is fixed against rotation relative to the spindle nut, extends axially with respect to the threaded spindle and is rotatable relative to the threaded spindle. A drive is connected to rotate one of the intermediate element and the threaded spindle; and the other of the intermediate element and the threaded spindle can be fixed against rotation.
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.
Abstract:
An improved lead screw actuator for use in applications including power vehicle windows is provided that significantly reduces the amount of machining that must be performed on the lead screw to enable secure attachment of a gear or pulley. The lead screw has a plurality of threads on its outer annular surface and a first and second axially spaced circumferential groove. A gear or pulley disposed about the lead screw has a female thread formed into an inner annular surface that is configured to engage at least one of the plurality of threads of the lead screw between the first and second grooves. A pair of rings are disposed within the first and second grooves in order to restrict axial movement of the gear or pulley on the lead screw.
Abstract:
A drive device for a hatch of a motor vehicle, wherein a spindle drive is provided with a threaded spindle and a spindle nut mounted on the threaded spindle, by which drive the first fastening element and the housing tube can be driven axially relative to each other. The spindle drive can be rotatably driven by an electric motor, where the output shaft of the motor can rotate the threaded spindle or a connecting component of a clutch. The spindle drive can be rotatably driven by two or more series-connected electric motors.
Abstract:
An adjusting system of a motor vehicle for the adjustment of a closing part is disclosed. The system includesa first and second casing extending oblong in a length-wise direction. The second casing has a smaller cross section than the first casing and is arranged within the first casing to be adjustable in a length-wise direction. A spindle for the relative adjustment of a first casing to the second casing is included and arranged within either or both of the first and second casings.The system also includes an electromotor and a transmission connected with either or both of the spindle and second casing. In addition, at least one spring is arranged within either or both of the first and second casings and operates length-wise, such that one of the casings is attached on the side of the motor vehicle body and another of the casings is attached to the closing side.
Abstract:
A vehicle decklid system uses a planetary gear drive to move a decklid relative to a vehicle body. The planetary gear drive includes a rotatable gear that is disposed between two fixed gears. One fixed gear is rigidly mounted to the decklid and one fixed gear is rigidly mounted to the vehicle body. A rotating link connects centers of the rotatable gear and two fixed gears. The combination of the planetary gear drive and rotating link make it possible to provide powered complex, two-dimensional motion of the decklid requiring a four-bar linkage.
Abstract:
An electric opening/closing device for vehicle, which has good layout characteristic of the vehicle and is provided with a highly-rigid attachment part, is provided. The vehicle electric opening/closing device comprises: a worm wheel meshed with a worm provided on a motor shaft of an electric motor; a planetary gear mechanism disposed coaxially with the worm wheel and decelerating rotation of the worm wheel to transmits it to an output gear; a gear case housing the worm wheel etc. and assembled to the electric motor; and a swing arm rotatably supported by the gear case between an output end linked to a back door and an input end linked to an output gear. An attachment plate for mounting the vehicle electric opening/closing device on the vehicle is sandwiched between the first case body and the second case body which constitute the gear case.
Abstract:
An electro-mechanical actuator for a window lift mechanism including a plurality of motors for driving an output shaft. The actuator may be incorporated into a window lift mechanism including a dual rack and pinion assembly, for driving the pinions along the racks. According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e.g. clutches. A clutch according to one embodiment includes locking pawls that resist back-drive. In another embodiment, locking cams rotate relative to a carrier to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism including a flexible carrier. The carrier flexes to prevent impact forces at an output gear train from coupling to an input gear train.
