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:
Getriebe zum Verschwenken einer Fahrzeugtür oder Fahrzeugklappe Die Erfindung betrifft ein Getriebe mit einer mit einem Motor verbindbaren Antriebswelle (6) zum Verschwenken einer mit einem Scharnierbügel (3) drehfest verbundenen Fahrzeugtür oder Fahrzeugklappe (2) um eine Schamierachse (4). Um eine sehr platzsparende Anordnung von Antrieb und Scharnierbügel (3) zu erreichen, schlägt die Erfindung vor, als Getriebe (5) ein Planetengetriebe vorzusehen, welches in den Schamierbügel (3) integriert wird. Dabei wird die Antriebswelle (6) des Getriebes (5) durch die Trägerachse des Sonnenrades (7) und das Hohlrad (12) des Planetengetriebes (5) durch das schamierachsenseitige Ende des Scharnierbügels (3) gebildet. Die Trägerachsen (18) der Planetenräder (10) sind dabei in mindestens einem seitlich von dem Scharnierbügel (3) angeordneten Trägerteil (14, 15) gelagert, welches fest mit der Fahrzeugkarosserie verbindbar ist und bei dem es sich vorzugsweise um einen Lagerbock (13) handelt, an dem der Scharnierbügel (3) schwenkbar angeordnet ist.
Abstract:
It is described a drive operator (10) for gates (CG) or doors comprising a gear motor formed by an electric motor and a reduction unit with an output shaft; an articulated arm (30, 132) to be connected to the gate or door which is turnable and has at one end (34, 134) a crown gear (36, 136); a transmission member (70, 170) to transmit the rotary motion of said output shaft to the crown gear. To improve the stability and the arm centering, one or more satellite gears (60, 160) are placed between the transmission member and the crown gear, so that the transmission member, the satellite gears and the crown gear form a kinematical arrangement of the epicyclical type.
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.
Abstract:
Apparatus for referencing a rotary drive with limits of movement required for that drive to take account of a particular application, for example the movement limits of opening or closing a garage door, comprising referencing a cam actuable switch (27) to the disposition of a drive in a range, said apparatus having an eccentric member (16) dependent on the drive, a spur gear (17) carried by the eccentric member and free to rotate relative to the eccentric member, a ring gear (19) with its inwardly directed teeth in an epicyclic meshing relationship with the spur gear (17), and a cam (23) rotatable with the spur gear adapted to interact with a switch (27), wherein there is an adaption or a capability whereby the switch is in a substantially fixed relationship with said ring gear (19).
Abstract:
An actuator assembly (20) for a powered sliding door system includes a housing (62) having a cavity (70) and a first cable reel (108) and a second cable reel (110) disposed in the cavity (70). The actuator assembly (20) includes a transmission assembly (138) being disposed in the cavity (70) and operatively connected to either the first cable reel (108) or the second cable reel (110) and a motor operatively connected to the transmission assembly (138). The actuator assembly (20) further includes a motor bracket (172) operatively connected to the transmission assembly (138) and enclosing the motor (192). The motor bracket (172) is adjustable relative to the housing (62) to form either a right-hand assembly, left-hand assembly or intermediate assembly for a right-hand and left-hand sliding door for a powered sliding door system (22).
Abstract:
To reduce the lift travel with a simple end position-recognition device which is reliable even on emergency manual operation and can be retrofitted, a radially projecting cam (2.7) connected to a drive shaft (2) of the drive unit engages during one revolution from tooth to tooth with the inner toothing of a ratchet (11) rotatable about and concentric with a spindle (11.1) offset parallel to the drive shaft (2). The cam (2.7) has an axial lift such that it can mesh with the ratchet (11) even with an axial shift of the drive shaft (2) in the event of emergency actuation.
