Abstract:
A powered actuator for moving a motor vehicle closure panel from a closed position to an open position and method of construction thereof. Powered actuator includes an electric motor configured to rotate a driven shaft and a gearbox coupled to the driven shaft. An extensible member extends through the gearbox to a proximal end on one side of the gearbox for attachment to one of a vehicle body or the closure member and to a distal end on an opposite side of the gearbox. Extensible member is configured to move between retracted and extended positions in response to rotation of the driven shaft. A contamination cover enshrouds the extensible member between the gearbox and the distal end of the extensible member. Contamination cover moves between an axially extended state and an axially retracted state while the extensible member moves between the respective retracted position and the extended position.
Abstract:
A spring winding device, a counterbalancing force adjustment device for a counterbalancing mechanism, and a method of adjusting an amount of force stored in a spring of a counterbalancing mechanism are provided. The spring winding device includes a support bracket, a worm gear, and a drive gear. The worm gear is rotatably coupled to the support bracket and includes a mount portion for coupling a first end cone thereto. The drive gear is rotatably disposed adjacent the support bracket and is drivingly engaged with the worm gear. A rotation of the drive gear causes the worm gear to rotate within the support bracket. The spring winding device does not require pretensioning using winding rods, maintains rigidity and alignment when a counterbalancing force is applied, and decreases a cost and a complexity of the counterbalancing mechanism.

Abstract:
A driving mechanism is arranged such that at least a part is contained within a space corresponding to the external shape of a driving motor, that is, within a space corresponding to a distance in the radial direction of the driving motor. The driving mechanism comprises a pinion, a transmission gear, a ring gear that forms a fixed axis, and a carrier. The pinion is connected to a rotary shaft of the driving motor. The transmission gear has a disk gear portion that meshes with the pinion, and a sun gear portion that is located on the same side as the pinion with respect to the disk gear portion. The carrier has a planet gear and rotates with a drum.
Abstract:
The present invention relates to a device for opening and closing a fuel tank inlet cover for a vehicle so as to lock or unlock the fuel tank inlet cover, which can be easily assembled without the influence of a working space. The device for opening and closing a fuel tank inlet cover for a vehicle includes a cover provided to a cap member (100) having a fuel tank inlet so as to rotate with respect to a hinge, a push-lift (200) provided such that an upper end portion thereof is lifted or lowered with respect to a through hole, which is formed in a coupling rib of the cover so as to be inserted into or withdrawn from the through hole, a lock rod (300) for moving forwards or backwards to one side or the other side such that the push-lift (200) is lifted or lowered so as to be locked or unlocked, and an actuator (400) for enabling the lock rod (300) to move forwards or backwards in one side or the other side direction.
Abstract:
An electric door operator for opening and closing one or a spaced pair of transit vehicle passenger doors for being mounted over an opening for the doors. A rotatable input shaft has an electric motor secured to the input shaft for driving the input shaft, a worm centrally positioned on the motor shaft, and an electric brake mounted to the input shaft at an end opposite of the electric motor. A drum cam lifts a pinion from a worm gear disconnecting the worm gear from an output gear train in an emergency.
Abstract:
A method for calibrating a powered actuator (1) for use in a vehicle is disclosed, with regard to an end position (6,7) of an actuating element (2) which is easy to achieve and conserves easily damaged mechanical components of the actuator made from plastic, rubber or similar. According to the invention, in a calibrating step, the actuator (1) is operated with recording and analysis of an actuation speed measured parameter (U) such that the actuating element (2) is moved in the direction of the end position (6,7) and reaching the end position (6,7) is recognised when the value of the actuation speed measured parameter (U) reaches or drops below a given threshold. A temperature parameter (T) characterising the temperature of the actuator (1) is evaluated before or during the calibration process. The calibration step is then only carried out if the value of the temperature parameter (T) does not exceed an upper temperature limit. An actuator (1) suitable for carrying out said method is also disclosed.
