Abstract:
The clutch includes a drive disk, a follower disk and a brake disk. When current flows, the follower disk is connected with the drive disk to transmit a power from a driving unit to a door-opening/closing mechanism. When no current flows, the follower disk is separated from the drive disk to cut off the power transmission from the driving unit to the door-opening/closing mechanism. In a state that the drive disk and the follower disk are separated from each other, the brake disk is connected to the follower disk to brake the door-opening/closing mechanism in the opening direction of the door, and to allow the door-opening/closing mechanism to move in the closing direction of the door.
Abstract:
Under a method to control a sliding speed in accordance with this invention, the motor is initially accelerated for a predetermined reference speed, and then during the initial acceleration period, if a rotational speed of the wire drum is of and above a given value, a difference between a rotational speed of the wire drum and a rotational speed of the motor is of and above a given value, and a rate of acceleration of the wire drum is of and above a given value, the rotational speed of the motor is reduced temporarily judging the slide door is in a state of abnormal acceleration, and then the motor is accelerated again at a lower rate than the initial acceleration toward the reference speed.
Abstract:
The invention relates to an electromagnetic friction clutch for arrangement within a drive train connecting a drive motor and a vehicle door. The vehicle door is reliably held in any intermediate position when a clutch is disconnected. To preserve the ability to carry out a manual emergency actuation of the vehicle door, a compression spring is provided acting upon an armature disk of the clutch in the axial direction in such a way that, with the clutch in the disconnected state, the armature disk is pressed against the frictional lining of a rotor part with a force which is sufficient to ensure that the vehicle door remains reliably in position. During a subsequent manual actuation of the vehicle door, the frictional connection between armature disk and frictional lining can be overcome.
Abstract:
Provided is a power actuator system for actuating a closure member (1) such as a trunk lid which is compact in size and has a minimized protrusion. A first link (8) is connected to an output shaft of a powered actuator (7), and a free end of the first link is connected to an end of a second link (9). The other end of the second link is pivotally connected to a hinge arm (4) which is fixedly attached to a closure member and pivotally supports the closure member to a fixed part such as a vehicle body. The first link is adapted to extend substantially from the output shaft towards the closure member as the first link swing around the output shaft, and the second link extends substantially perpendicularly with respect to the center line.
Abstract:
An apparatus is provided in which a motor 11 with reduction gears, a clutch 12 and a gas stay are provided between a vehicle body 2 and a tailgate 1 so that a fully opened position of the tailgate can be held by virtue of a thrust of the gas stay only, and in this apparatus, when a closure of the tailgate from its own weight is detected after the motor with reduction gears is disconnected, the motor with reduction gears is connected to the tailgate to drive to forcibly close it after the tailgate is driven to be opened to the fully opened position thereof. By this construction, when the holding force of the opened position is short, since the tailgate is closed after it is opened to the fully opened position once, cargo loading and unloading work can be completed while the tailgate is so closed.
Abstract:
An integrated gas strut actuator strut assembly particularly adapted for providing power actuation of a motor vehicle lift gate or other opening closure. The system integrates the function of a counterbalancing gas spring and that of a electrically powered actuator. The system incorporates a strut assembly including a gas charged cylinder, and internal plunger and a threaded rod. Rotation of the threaded rod through a cable drive system causes the internal plunger to be advanced or retracted within the cylinder. Another feature of the invention are various embodiments of couplers between the gas cylinder plunger and rod and connectors for the assembly to the vehicle.
Abstract:
A clutch mechanism of the power device includes a movable gear member which is rotated integrally with a wheel and engaged with a stationary gear member when moved in a first direction and disengaged from the stationary gear member when moved in a second direction opposite to the first direction, an armature for pushing out the movable gear member in the first direction when rotated relatively to the movable gear member, and an electromagnetic coil for applying brake resistance to the armature by attracting the armature by the magnetic force to restrict a co-rotating state of the armature and the movable gear member. The armature has a clutch holding surface for maintaining a clutch-engaged state where the movable gear member and the stationary gear member is engaged with other even when the electromagnetic coil is turned off in the clutch-engaged state.
Abstract:
The invention relates to an apparatus (1) for opening and closing a door (2) which is arranged so that it can slide on a vehicle (3). The apparatus comprises an engaging element (5), such as a cable, connected to the door (2), and a drive wheel (6) designed to act upon the engaging element (5). A transmission (7) is operatively connected to the drive wheel (6) and the transmission (7) is designed to transmit power to the drive wheel (6) via at least a first gear and a second gear. In one embodiment the transmission may have a neutral position so that the drive wheel (6) can rotate freely. A position sensor (8) is connected to the sliding door (2) in order to detect when the sliding door (2) has reached a predetermined position in the door opening. The transmission (7) then changes gear from the first gear to the second gear. The invention also relates to a vehicle provided with the apparatus according to the invention and to a method of fitting the apparatus according to the invention to a vehicle.
Abstract:
A locking arrangement for a door system of a transit vehicle includes a combination of a lock mechanism and an electromagnetic brake. The lock mechanism enables positive locking of at least one door but does not require substantial contact between moving and stationary lock elements. The lock mechanism is connected with the manual release means for door opening during an emergency. The electromagnetic brake maintains door seal compression in the closed and locked condition which improves sealing capabilities and provides for reliable lock mechanism operation. Such combination provides locking redundancy and meets various requirements regarding annunciation and manual release operation.
Abstract:
An electromagnetic frictionally engaged clutch for arranging inside a drive train connecting a drive motor and a vehicle door or flap. The arrangement ensures that the vehicle door is securely held in each intermediate position, when the clutch is in an idle state, while maintaining the possibility of a manual emergency actuation of the vehicle door. The rotor includes at least one permanent magnet in addition to the electric coil, such that when a current does not pass through the coil, the armature disk is pressed against the friction lining of the rotor, with a force which is strong enough for the vehicle door or vehicle flap to securely remain in position occupied when the clutch is an idle state, and for the friction engagement between the armature disk and the friction lining to be overcome when the vehicle door or vehicle flap is subsequently manually actuated.
