Abstract

The drive system is designed so that the drive motor (10) is fitted laterally covered and can be arranged so that it is relatively weak. The motor is designed changeable in length by the power application of a lifting piston integrated in it. The drive motor has one end located with limited swiveling ability at the vehicle bodywork and at the other end engages at a swivel lever (8) connected rotationally proof with the drive shaft (4). The length of the swivel lever is selected to suit the desired swivel torque for the flap e.g. luggage compartment cover or an engine bonnet.

Description

Die Erfindung betrifft eine Antriebsvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a drive device according to the preamble of Claim 1.

Motorisch betriebene Antriebsvorrichtungen zum Schwenken insbesondere von Heckklappen von Kraftfahrzeugen, die zum Abdecken eines Gepäckraums dienen, finden zwecks Erhöhung des Bedienungskomforts in zunehmendem Umfange Einsatz. Dabei werden häufig zur Unterstützung des Antriebsmotors Gasfedern übernommen, die primär die Aufgabe haben, das Eigengewicht der Heckklappe aufzunehmen. So sieht eine im Einsatz befindliche Antriebsvorrichtung zwei Mehrgelenkscharniere vor, von denen das eine mit einer Gasfeder und das andere mit einem durch ein Druckmedium betriebenen längenveränderbaren Antriebsmotor bestückt ist. Nachteilig bei dieser Konstruktion ist die Tatsache, daß dem Antriebsmotor zugeordnete Zu- und Ableitungen für das Druckmedium zu bewegten Stellen des Mehrgelenkscharniers geführt werden müssen.Motorized drive devices for pivoting in particular Tailgates of motor vehicles used to cover a luggage compartment, are used increasingly to increase the ease of use. Gas springs are often used to support the drive motor, which primarily have the task of absorbing the dead weight of the tailgate. So a drive device in use provides two multi-joint hinges, one with a gas spring and the other with one through one Media-operated variable-length drive motor is equipped. Disadvantageous in this construction is the fact that the drive motor associated supply and Derivatives for the pressure medium to moving points of the multi-joint hinge must be performed.

Demgegenüber sieht die gattungsbildende DE 197 44 908 A1 einen am Fahrzeugaufbau ortsfest gelagerten Antriebsmotor vor, dem ein Getriebe und eine Überlastkupplung zugeordnet sind und dessen Getriebeausgangswelle mit der Antriebswelle des Mehrgelenkscharniers fluchtet sowie mit dieser drehfest verbunden ist. Dieser Antriebsmotor baut in Achsrichtung relativ groß, wodurch er im eingebauten Zustand einen relativ großen Platzbedarf in Querrichtung des Fahrzeugs besitzt und es Schwierigkeiten machen kann, ihn seitlich gegen das Innere beispielsweise des Kofferraums abgedeckt unterzubringen. Außerdem muß ein relativ großer Aufwand in Gestalt eines besonderen Getriebes zwecks Erzeugung genügend großer Schwenkmomente für die Klappe bei gegebener begrenzter Leistung des eigentlichen Antriebsmotors getrieben werden. In contrast, the generic DE 197 44 908 A1 sees one Vehicle body stationary drive motor, which a gear and a Overload clutch are assigned and its transmission output shaft with the The drive shaft of the multi-joint hinge is aligned and connected to it in a rotationally fixed manner is. This drive motor builds relatively large in the axial direction, which makes it installed Condition has a relatively large space requirement in the transverse direction of the vehicle and it Difficulties can be him laterally against the inside, for example To accommodate the trunk covered. In addition, a relatively large effort in Shape of a special gear for the purpose of producing sufficiently large Swing moments for the flap for a given limited power of the actual one Drive motor are driven.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Antriebsvorrichtung unter Wahrung ihrer Vorteile zu schaffen, die zu ihrer Unterbringung nur wenig Platz, insbesondere in Querrichtung des Fahrzeugs, erfordert, und die mit sehr einfach aufgebauten und demgemäß ebenfalls platzsparenden Einrichtungen zur Anpassung der gegebenen Leistung des Antriebsmotors an die erforderlichen Schwenkmomente bestückt ist.The invention has for its object a generic drive device while preserving their benefits, creating little space for their accommodation, especially in the transverse direction of the vehicle, and requires very simple built and accordingly also space-saving facilities for adaptation the given power of the drive motor to the required swivel torques is equipped.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbildungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the characterizing Features of the main claim describe advantageous embodiments of the invention the subclaims.

Ein besonderer Vorteil der erfindungsgemäßen Antriebsvorrichtung ist in ihrem sehr geringen Platzbedarf insbesondere in Querrichtung des Fahrzeugs zu sehen, da die Einrichtung zur Anpassung der Leistung des Antriebsmotors an die erforderlichen Schwenkmomente auf einen Schwenkhebel mit solcher Länge reduziert ist, daß dieser einen zur Momentenerzeugung ausreichenden Hebelarm bildet. Hinsichtlich der Platzverhältnisse günstig macht sich ferner die Tatsache bemerkbar, daß der Antriebsmotor als sehr schmale Kolben-Zylinder-Anordnung ausgebildet sein kann und alle Einrichtungen zu seiner Ansteuerung ebenfalls ortsfest im Fahrzeugaufbau an einer anderen, weniger platzkritischen Stelle angeordnet sein können, da die Verbindung zwischen ihnen und dem Antriebsmotor über praktisch festliegende Leitungen erfolgen kann. Das gilt sowohl dann, wenn zur Betätigung des Antriebsmotors, also zur Energiezufuhr, ein Strömungsmittel, beispielsweise Druckluft oder Drucköl, Einsatz findet, als auch dann, wenn es sich um eine elektrische, d.h. in der Regel elektromagnetische, Betätigung handelt.A particular advantage of the drive device according to the invention is its very small space requirement, especially in the transverse direction of the vehicle, since the Device for adapting the power of the drive motor to the required Swing moments on a swivel lever with such a length is reduced that this forms a lever arm sufficient for generating torque. With regard to the Favorable space also makes the fact that the Drive motor can be designed as a very narrow piston-cylinder arrangement and all devices for its control also fixed in the vehicle body at one other, less space-critical point can be arranged because of the connection between them and the drive motor via practically fixed lines can. This applies both when actuating the drive motor, that is Energy supply, a fluid, such as compressed air or oil, use takes place, as well as if it is an electrical, i.e. usually electromagnetic, actuation.

Ein Ausführungsbeispiel der Erfindung für den Fall der Antriebsvorrichtung für eine Heckklappe wird im folgenden anhand der Zeichnung erläutert, die lediglich die Elemente der Antriebsvorrichtung, nicht aber weitere Teile des Fahrzeugs bzw. den Deckel, darstellt.An embodiment of the invention for the case of the drive device for a Tailgate is explained below with reference to the drawing, which is only the Elements of the drive device, but not other parts of the vehicle or the Cover.

Das hier als Viergelenkscharnier ausgebildete Mehrgelenkscharnier 1 besitzt das Scharnierblatt 2, an dem der Deckel befestigt ist. Üblicherweise sind zwei derartige Scharniere vorhanden, eines auf der linken Seite (das ist das gezeichnete Scharnier 1), das zweite auf der rechten Seite des Fahrzeugs. In der dargestellten im wesentlichen senkrechten Lage des Scharnierblatts 2 befindet sich der Deckel in seiner geöffneten Stellung; zum Schließen des Deckels muß dieser in eine im wesentlichen horizontale Lage herabgeschwenkt werden, so daß dann auch das Scharnierblatt 2 horizontal verläuft.The multi-joint hinge 1 designed here as a four-joint hinge has this Hinge leaf 2 to which the lid is attached. Usually two are Hinges are present, one on the left side (this is the hinge 1 shown), the second on the right side of the vehicle. In the illustrated essentially vertical position of the hinge leaf 2, the lid is in its open Position; to close the lid it must be in a substantially horizontal Position swung down, so that then the hinge leaf 2 horizontally runs.

Der Scharnierarm 3 ist drehfest mit der Antriebswelle 4 verbunden (sie ist in der gewählten Explosionsdarstellung außerhalb einer Aufnahmeöffnung im Scharnierarm 3 gezeichnet), die in dem Träger 5 gelagert ist. Dieser ist seinerseits zur starren Befestigung an dem nicht dargestellten Fahrzeugaufbau eingerichtet, beispielsweise mit Schraubenlöchern für Befestigungsschrauben versehen. Drehfest auf dem im zusammengebauten Zustand die Lagerbohrung 6 in dem Träger 5 durchsetzenden Fortsatz 7 der Antriebswelle 4 sitzt der Schwenkhebel 8, an dem im Bereich seines freien Endes, d.h. bei 9, der durch Energiezufuhr längenveränderbare Antriebsmotor 10 angreift. In diesem Ausführungsbeispiel handelt es sich um einen hydraulischen Antriebsmotor, der im wesentlichen eine Kolben-Zylinder-Anordnung enthält, deren durch den Kolben getrennte beide Kammern über Zu- und Ableitungen 11 und 12 mit einer hydraulischen Pumpe 13 in Verbindung stehen. Diese Pumpe 13 kann ebenfalls ortsfest im Fahrzeugaufbau angeordnet werden, und zwar an einer hinsichtlich der Platzverhältnisse unkritischen Stelle, gegebenenfalls entfernt vom Antriebsmotor 10.The hinge arm 3 is rotatably connected to the drive shaft 4 (it is in the selected exploded view outside a receiving opening in the hinge arm 3 drawn), which is mounted in the carrier 5. This in turn is rigid Attachment to the vehicle body, not shown, set up, for example with Provide screw holes for fastening screws. Rotatable on the im Assembled state penetrating the bearing bore 6 in the carrier 5 Extension 7 of the drive shaft 4 sits the pivot lever 8 on which in the area of his free end, i.e. at 9, the drive motor 10 variable in length by the supply of energy attacks. In this embodiment, it is a hydraulic one Drive motor, which essentially contains a piston-cylinder arrangement, the separated by the piston both chambers via feed and discharge lines 11 and 12 with a hydraulic pump 13 are connected. This pump 13 can also be arranged in a fixed position in the vehicle body, namely at one with regard to the Uncritical space, possibly removed from the drive motor 10.

Der Antriebsmotor 10 ist im Bereich seines anderen, in der Figur linken Endes abgestützt am Träger 5, und zwar über ein zumindest begrenzte Schwenkbewegungen in senkrechter Richtung zulassendes Lager. Der Schwenkhebel 8 ist im wesentlichen senkrecht ausgerichtet, d.h. im wesentlichen senkrecht zur Längsachse des Antriebsmotors 10, so daß dessen Längenänderungen im wesentlichen in Richtung von Tangenten an den Schwenkkreis der Anlenkstelle 9 verlaufen.The drive motor 10 is in the area of its other end on the left in the figure supported on the carrier 5, namely via an at least limited pivoting movements bearing in the vertical direction. The pivot lever 8 is essentially aligned vertically, i.e. essentially perpendicular to the longitudinal axis of the Drive motor 10 so that its changes in length substantially in the direction of Tangents to the swivel circle of the articulation point 9 run.

In der dargestellten Betriebsphase (Deckel voll geöffnet) hat der Antriebsmotor 10 durch entsprechende Zufuhr von Druckenergie über die Leitungen 11 und 12 seine größte Länge erreicht, d.h. durch Verschwenken des Arms 3 des Viergelenkscharniers 1 und demgemäß Hochschwenken des Arms 14 desselben ist das Scharnierblatt in seine dargestellte senkrechte Lage verschwenkt. Wird nun durch entsprechendes Vertauschen der Leitungen 11 und 12 als Zufuhr- und Abfuhrleitungen der Antriebsmotor 10 hinsichtlich seiner Länge wieder verringert, so schwenkt der Schwenkhebel 8 etwas im Uhrzeigersinne, und das Scharnierblatt 2 wird gleichsam um das Gelenk 15 ebenfalls im Uhrzeigersinne verschwenkt.In the operating phase shown (cover fully open), the drive motor 10 is through corresponding supply of pressure energy via lines 11 and 12 its largest Length reached, i.e. by pivoting the arm 3 of the four-bar hinge 1 and accordingly pivoting the arm 14 of the same is the hinge leaf in his shown vertical position pivoted. Is now through appropriate Swap lines 11 and 12 as supply and discharge lines Drive motor 10 reduced in length, so the pivots Swivel lever 8 slightly clockwise, and the hinge leaf 2 is, as it were, around the joint 15 is also pivoted clockwise.

In diesem Ausführungsbeispiel ist angenommen, daß das Viergelenkscharnier 1 mit einer üblichen Gasfeder 16 bestückt ist, die eine Entlastung des Antriebsmotors 10 von durch das Gewicht der Klappe ausgeübten Kräften und Momenten sicherstellen soll.In this embodiment, it is assumed that the four-bar hinge 1 with a conventional gas spring 16 is equipped, which relieves the drive motor 10 of to ensure that forces and moments are exerted by the weight of the flap.

Am Schwenkhebel 8 kann ein bei 17 angedeuteter Weg- oder Winkelsensor angreifen, der bei Erreichen bestimmter Schwenkwinkel des Deckels Signale an das Steuergerät 19 für die Pumpe 13 liefert, so daß eine

Figure 00040001
schwenkwinkelgetreue" Ein- und Ausschaltung der Energiezufuhr zum Antriebsmotor 10 sichergestellt ist.On the pivot lever 8, a path or angle sensor indicated at 17 can engage, which, when certain pivot angles of the cover are reached, delivers signals to the control unit 19 for the pump 13, so that a
Figure 00040001
pivoting angle true "switching on and off the energy supply to the drive motor 10 is ensured.

Zumindest die Teile 8 und 10 können mit dem Träger 5 vor dessen Einbau in den Fahrzeugaufbau zu einer Montageeinheit verbunden sein.At least the parts 8 and 10 can be with the carrier 5 before its installation in the Vehicle body to be connected to an assembly unit.

Auch das Scharnier auf der anderen Fahrzeugseite kann mit einem Antriebsmotor ausgerüstet sein.The hinge on the other side of the vehicle can also be powered by a drive motor be equipped.

Mit der Erfindung ist demgemäß eine gattungsgemäße Antriebsvorrichtung geschaffen, die Energiezufuhrleitungen zwischen relativ zueinander bewegten Teilen zumindest weitgehend vermeidet, die schmal baut und die mit einfachen Mitteln, nämlich allein durch entsprechende Dimensionierung der Länge des Schwenkhebels 8, eine erforderliche Anpassung zwischen der Leistung des Antriebsmotors einerseits und den erforderlichen Schwenkmomenten für den Deckel andererseits erlaubt.The invention accordingly provides a generic drive device, the energy supply lines at least between parts moving relative to one another largely avoids building narrow and using simple means, namely alone by appropriate dimensioning of the length of the pivot lever 8, a required adjustment between the power of the drive motor on the one hand and the required pivoting moments for the lid on the other hand allowed.
