Abstract:
A device for controlling a door operated by a motor includes an opening/closing mechanism that opens and closes the door, and a gear mechanism that includes a plurality of tooth units each of which has different mesh and that conveys a torque of the motor to the opening/closing mechanism. The tooth units include a low-torque tooth unit that convey a relatively low torque, and a high-torque-tooth unit that conveys a relatively high torque. The torque conveyed to the opening/closing mechanism is changed by selecting a tooth unit based on a position of the door at the time of starting an opening or closing operation of the door.
Abstract:
A braking apparatus has a main body for connection to one of a frame and a closure member mounted on the frame to undergo linear reciprocating movement between open and closed positions of the closure member. A tubular shaft is mounted in a main body for undergoing rotation. A resistance member is rotatably mounted on the tubular shaft and is disposed in an interior space of the main body containing a braking fluid. A spiral rod for connection to the other of the frame and the closure member is screw-threadably engaged with the tubular shaft so that the tubular shaft undergoes rotation when the spiral rod and the tubular shaft are relatively moved in an axial direction of the spiral rod. When the closure member undergoes linear reciprocating movement, the main body or spiral rod relatively moves in the axial direction of the spiral rod, the tubular shaft and the resistance member undergo rotational movement, and the resistance member receives a resistance of the braking fluid so that the tubular shaft rotates under a braking force of the braking fluid and reduces a movement speed of the closure member.
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:
A hinge for a vehicle flap is provided which includes a first hinge part (2), mounted on one of the door arrangement elements flap and flap frame, a second hinge part (3), mounted on the other door arrangement element, a hinge pin (4) which is linked with the first hinge part (2) and the second hinge part (3) so as to be pivoted about a first pivoting axis (S), and a lever arrangement (17), coupling the first hinge part (2) with the second hinge part (3). Said lever arrangement comprises at least on first lever (20), said lever (20) being linked with the hinge part (2) located on the flap so as to be pivoted. The The hinge allows for a safe and controlled opening and closing of an automotive flap. For this purpose, a fixing device (24) for a motor (16) is provided on the hinge part (2) disposed on the flap and the first lever (20) of the lever arrangement (17) is rotationally driven by said motor (16).
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 driving device for driving an open/close member that is designed to open and close an open portion of a body includes a driving source generating a driving force, a force transmission mechanism disposed between the driving source and the open/close member and serving for transmitting the driving force thereto, and a load regulator for interrupting the driving force transmission when an excessive force is applied to the force transmission mechanism from the open/close member.
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.
