Abstract:
A liftgate actuating assembly is disclosed for moving a liftgate of a motor vehicle between open and closed positions. The liftgate actuating assembly includes a motor that is fixedly secured to the motor vehicle. The motor has an output shaft capable of bi-directional rotation. A drive gear rotates about a drive shaft and is operatively connected to the output shaft to be rotated thereby. A cable drum is rotatably mounted to the drive shaft. The cable drum is coupled to the drive gear and is rotated thereby. The cable drum includes a cable wrapped thereabout between a drum end fixedly secured to the cable drum and a liftgate end fixedly secured to the liftgate. The cable is used to retract the liftgate from the open position to the closed position. A linkage is operatively connected to the drive gear. The linkage is from a retracted position to an extended position such that the linkage forces the liftgate from the closed position to the open position when the linkage moves from the retracted position to the extended position. The linkage includes a slot that provides lost motion within the linkage. This allows the liftgate to be move manually to the closed position without the motor being activated.
Abstract:
Die Erfindung betrifft einen Antrieb zur automatischen Betätigung einer Fahrzeugtür, insbesondere der Reckklappe eines Kraftfahrzeuges, wobei der Antrieb (4) über eine Abtriebswelle (5) mit der Fahrzeugtür (1) oder einer Übertragungseinrichtung (6) verbindbar ist, welche eine der Schwenkbewegung der Fahrzeugtür (1) entsprechende Schwenkbewegung ausführt, und wobei der Antrieb (4) mindestens eine erste mit einer elektronischen Auswerteeinrichtung (21) verbindbare Sensoreinrichtung (7) zur Erfassung der jeweiligen winkelmässigen Lage der Fahrzeugtür (1) umfasst. Zur Ausnutzung der Vorteile einer inkremental arbeitenden Positionsmessung der Fahrzeugtür (1), bei welcher aber nach einem Stromausfall eine erneute Kalibrierung nicht erst nach Erreichen der Endstellungen der Fahrzeugtür (1) erforderlich ist, schlägt die Erfindung vor, den gesamten Schwenkwinkel ( α ) der Fahrzeugtür (1) in mindestens drei aufeinanderfolgende Zonen (Schwenkwinkelbereichen) ( α 1- α 4) einzuteilen, wobei die einzelnen Schwenkwinkelbereiche ( α 1- α 4) durch eine erste zur Absolutwerterfassung geeignete Sensoreinrichtung (7) ermittelbar sind. Die Erfassung des Schwenkwinkels der Fahrzeugtür innerhalb der einzelnen Zonen ( α 1- α 4) erfolgt dann mit Hilfe einer zweiten Sensoreinrichtung (8), welche mindestens einen inkremental arbeitenden Messwertgeber umfasst.
Abstract:
A drive assembly moves a vehicle closure panel from an open to a closed condition. The drive assembly has a housing and a motor mounted on the housing. A drum and gear assembly is rotatably mounted on the housing. The drum and gear assembly has a drum having a helical groove, a gear in driving engagement with the motor, and a spring biasing the drum in a winding direction relative to the gear. The drum and gear have a lost motion connection therebetween. A cable has an end connected to the closure panel and an opposite end connected to the drum about the helical groove in the winding direction. The drum rotates in the winding direction relative to the stationary gear as the closure panel is manually moved from the open to the closed condition with the spring maintaining a cable tension. The drum and gear rotate together in the winding direction upon energizing the motor effecting powered movement of the closure panel to the closed condition. The motor is afterwards energized in an opposite direction counter-rotating the gear relative to the drum back to a start position.
Abstract:
A power-operated system (32) for actuating the rear doors or liftgates (18) of motor vehicles (10) is disclosed. The system includes a strut assembly having two struts (30), each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut (30) is connected to a powered moving arm (40). To open the door, the arms (40) move to change the angular orientation of the struts (30) such that they have a substantial mechanical advantage. In this position, the force provided by the struts (30) overcomes the weight bias of the door (18), thus opening the door. To close the door, the moving arms (30) change the angular orientation of the struts (30) such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore allowing the door (18) to fall closed under its own weight bias. A control system for controlling the power-operated system (32) is also disclosed.
Abstract:
A temporarily holding device for temporarily holding an opening/closing body such as a sliding door for a vehicle in such a manner as to allow it to be moved from a halted state with a required operating force, comprising, in order not to fluctuate the moving resistance remarkably in any condition by providing the moving resistance of a required limit in the form of electrical control while the opening/closing body is being halted, an opening/closing body movably supported on a guiding mechanism, a motor-driven clutch for freely connecting and/or disconnecting the guide mechanism to and/or from an opening/closing body holding mechanism and a clutch driving means for regulating the transmission maintaining force of the motor-driven clutch, wherein the clutch driving means is designed to set the transmission maintaining force of the motor-driven clutch when the opening/closing body is halted with a required opening smaller than when it is in motion.
Abstract:
Die Erfindung betrifft eine Einzugvorrichtung, insbesondere für Schiebetüren, Schubladen oder dergleichen mit einem Auslöseteil, das eine Mitnehmeraufnahme aufweist, wobei das Auslöseteil zwischen einer ersten und einer zweiten Parkposition verstellbar ist, wobei das Auslöseteil in der ersten Parkposition die Mitnehmeraufnahme in eine erste und in der zweiten Parkposition die Mitnehmeraufnahme in eine zweite Richtung freigibt, und wobei das Auslöseteil zwischen den Parkpositionen mit zwei entgegensetzt wirkenden Rückstellvorrichtungen koppelbar ist. Mit dieser Einzugvorrichtung wird eine lagegenaue Fixierung der Schiebetür in der Zwischenstellung mit geringem baulichen Aufwand möglich.
Abstract:
A door operator with an electrical back check feature is disclosed. Embodiments of the present invention are realized by a motorized door operator (20, 200) that electrically creates a back check force for an opening door (22). The door operator simulates the back check normally created by hydraulic means in convention door closers, but without the use of pistons, springs or hydraulic fluid. The door operator includes a motor (202, 550) disposed to operatively connect to a door so that the door will open when the motor moves, and a position sensor (120, 240, 510) to determine a position of the door. A processor (552) is programmed to exert a closing force on the door in the back check region. In some embodiments, the closing force is exerted by injecting a voltage into the electric motor of the door operator.
Abstract:
The invention relates to a drive unit for automatically actuating a vehicle door, especially the tailgate of a motor vehicle. The inventive drive unit (4) can be connected to the vehicle door (1) or a transmission device (6) via an output shaft (5), said transmission device (6) performing a pivoting movement that corresponds to the pivoting movement of the vehicle door (1). The drive unit (4) comprises at least one first sensor unit (7) that can be connected to an electronic evaluation unit (21) and detects the respective angular position of the vehicle door (1). The aim of the invention is to make use of the advantages of an incremental measurement of the position of the vehicle door (1) without having to wait for the vehicle door (1) to reach its final position to be able to recalibrate following a power outage. Said aim is achieved by dividing the entire pivot angle (alpha) of the vehicle door (1) into at least three successive zones (pivot angle ranges) (alpha1-alpha4), the individual pivot angle ranges (alpha1-alpha4) being determined by a first sensor unit (7) that detects absolute values. The pivot angle of the vehicle door within the individual zones (alpha1-alpha4) is then detected with the aid of a second sensor unit (8) which encompasses at least one incremental measuring transducer.
