Description

Die Erfindung betrifft eine Hebebühne, insbesondere verfahrbare Hebebühne, zum Anheben von Fahrzeugen.The invention relates to a lifting platform, in particular a movable lifting platform, for lifting vehicles.

Aus der US 2004/0011594 A1 ist eine Hebebühne bekannt, welche zwei einander gegenüberliegende Hubsäulen umfasst, entlang denen jeweils eine Lastaufnahme auf- und abbewegbar ist. Am oberen Ende der beiden Hubsäulen ist ein Querträger befestigt. Dieser Querträger dient zur gegenseitigen Abstützung der Hubsäulen und zur Aussteifung der Hubsäule. Der Querträger kann formschlüssig mit den Hubsäulen verbunden werden.From the U.S. 2004/0011594 A1 a lifting platform is known which comprises two lifting columns located opposite one another, along each of which a lifting device can be moved up and down. A cross member is attached to the upper end of the two lifting columns. This cross member serves to support the lifting columns mutually and to stiffen the lifting column. The crossbeam can be positively connected to the lifting columns.

Aus der CN 105035998 A ist eine Fahrschienenhebebühne bekannt, bei welcher jede Fahrschiene durch eine Doppelschere auf- und abbewegbar ist. Jeweils eine Scherenhälfte der Doppelschere für die jeweilige Fahrbühne ist durch ein Rohr fest miteinander verbunden.From the CN 105035998A a rail lifting platform is known in which each rail can be moved up and down by double scissors. One scissor half of the double scissor for the respective mobile platform is firmly connected to each other by a tube.

Aus der DE 36 05 650 C2 ist eine mobile hydraulische Hebebühne zum Anheben von Fahrzeugen in Überkopfhöhe bekannt. Diese mobile Hebebühne umfasst eine Bodengruppe, welche beim Anheben von Fahrzeugen ortsfest aufliegt. Beim Nichtgebrauch kann diese Hebebühne mittels eines Fahrwerkes in eine weitere Gebrauchs- oder Verstauposition verfahren werden. Die Bodengruppe der Hebebühne umfasst zwei Bodengruppenhälften sowie ein Mittelteil, wobei die beiden Bodengruppenhälften über das Mittelteil fest miteinander verbunden und zueinander angeordnet sind. Jede Bodengruppenhälfte weist einen Antrieb auf, durch welchen eine Parallelogrammführungsvorrichtung der Bodengruppenhälfte auf und ab bewegbar ist. Diese Parallelogrammführungsvorrichtung umfasst einen Lastarm und eine Führungsstange, sodass beim Heben und Senken der Parallelogrammführungsvorrichtung ein am freien Endbereich angeordneter Träger horizontal ausgerichtet bleibt. Der an der Parallelogrammführungsvorrichtung vorgesehene Träger nimmt zwei schwenkbar am Träger angeordnete Tragarme auf. Diese Tragarme können aus einer Nichtgebrauchsposition, bei der die Tragarme entgegengesetzt ausgerichtet und parallel zur Parallelogrammführungsvorrichtung positioniert sind, in eine Gebrauchsposition geschwenkt werden, um ein zwischen den Bodengruppenhälften und in die Hebebühne eingefahrenes Fahrzeug anzuheben.From the DE 36 05 650 C2 a mobile hydraulic lifting platform for lifting vehicles overhead is known. This mobile lifting platform includes a floor assembly that rests in a fixed position when vehicles are lifted. When not in use, this lifting platform can be moved to another use or storage position by means of a chassis. The floor assembly of the lifting platform comprises two floor assembly halves and a middle part, the two floor assembly halves being firmly connected to one another and arranged relative to one another via the middle part. Each underbody half has a drive, by means of which a parallelogram guidance device of the underbody half can be moved up and down. This parallelogram guide device comprises a load arm and a guide rod, so that a carrier arranged at the free end area remains horizontally aligned when the parallelogram guide device is raised and lowered. The carrier provided on the parallelogram guide device accommodates two support arms arranged pivotably on the carrier. These support arms can be adjusted from a non-use position in which the support arms are oppositely oriented and parallel to the Positioned parallelogram linkage device, are pivoted into a use position to raise a vehicle retracted between the underbody halves and into the lift.

Jede Bodengruppenhälfte ist an dem Mittelteil, welches in Form eines Schutzrohres ausgebildet ist, befestigt. Das Mittelteil weist am jeweiligen Ende einen Flanschabschnitt auf, der mit einer Seitenfläche des Gehäuses der Bodengruppenhälfte verschraubt ist.Each half of the underbody is fastened to the central part, which is designed in the form of a protective tube. The middle part has a flange section at the respective end, which is screwed to a side face of the housing of the underbody half.

Die Anforderungen an die Steifigkeit solcher Hebebühnen als auch die Ausrichtung der Hebevorrichtungen der Hebebühne zueinander steigen stetig an.The requirements for the rigidity of such lifting platforms as well as the alignment of the lifting devices of the lifting platform to one another are constantly increasing.

Der Erfindung liegt die Aufgabe zugrunde, eine Hebebühne vorzuschlagen, bei welcher die Steifigkeit der Bodengruppe erhöht und die Montage der Bodengruppe und insbesondere die Justierung der Ausrichtung der Hebevorrichtungen vereinfacht ist.The invention is based on the object of proposing a lifting platform in which the rigidity of the floor assembly is increased and the assembly of the floor assembly and in particular the adjustment of the alignment of the lifting devices is simplified.

Diese Aufgabe wird durch eine Hebebühne zum Anheben von Fahrzeugen gelöst, bei welchen das Mittelteil mit dem jeweiligen Gehäuse der Bodengruppenhälften zur Bildung der Bodengruppe durch eine formschlüssige Steckverbindung miteinander verbunden ist. Dadurch kann eine erhöhte Kraftübertragung ermöglicht sein, da durch das formschlüssige Ineinandergreifen der Verbindungselemente ein verbesserter Kraftfluss ermöglicht ist. Gleichzeitig kann in einfacher Weise bei der Montage des Mittelteils zum Gehäuse der Bodengruppenhälften eine selbständige Ausrichtung zueinander erfolgen. Die formschlüssige Steckverbindung umfasst zumindest ein erstes Verbindungselement in einem bodennahen Bereich und vorzugsweise stirnseitig am Mittelteil zumindest ein weiteres Verbindungselement am Gehäuse, insbesondere an einer Seitenfläche des Gehäuses der Bodengruppenhälfte, wobei das zumindest eine weitere Verbindungselement komplementär zum ersten Verbindungselement ausgebildet ist. Dadurch kann eine einfache und sichere Montage durch das Zusammenführen des Mittelteils zum Gehäuse der Bodengruppenhälfte gegeben sein und ergänzend beim Zusammenführen des Mittelteils zum Gehäuse bereits eine lagerichtige Ausrichtung erfolgen.This object is achieved by a lifting platform for raising vehicles, in which the central part is connected to the respective housing of the floor assembly halves to form the floor assembly by a positive plug connection. As a result, increased power transmission can be made possible, since an improved power flow is made possible by the form-fitting interlocking of the connecting elements. At the same time, when assembling the central part to the housing of the floor assembly halves, an independent alignment with one another can be carried out in a simple manner. The form-fitting plug-in connection comprises at least one first connecting element in an area near the floor and preferably at least one further connecting element on the front of the central part on the housing, in particular on a side surface of the housing of the underbody half, with the at least one further connecting element being designed to complement the first connecting element. As a result, simple and safe assembly can be achieved by merging the central part into the housing of the underbody half and, in addition, when Merging the middle part to the housing already done a correct positional alignment.

Bevorzugt bilden die Verbindungselemente eine auf Zugkraft belastbare formschlüssige Steckverbindung. Dadurch kann eine erhöhte Steifigkeit der Hebebühne erzielt werden. Beim Anheben eines Fahrzeuges werden die Träger mittels der Hebevorrichtung in eine Arbeitsposition angehoben. Dabei wirkt eine Hebelkraft auf die Hebevorrichtung in Richtung einer Längsmittelachse der Hebevorrichtung und erzeugt ein zur Längsmittelachse wirkendes Drehmoment. Durch die formschlüssige Steckverbindung kann in einem bodennahen Bereich zwischen dem Mittelteil und dem jeweiligen Gehäuse der Bodengruppenhälfte diesem Drehmoment entgegengewirkt werden. Zusätzlich lösbare Befestigungsmittel können entbehrlich sein. Durch diese formschlüssige Steckverbindung kann eine Aussteifung der Bodengruppe erzielt werden.The connecting elements preferably form a form-fitting plug-in connection that can be subjected to tensile forces. As a result, increased rigidity of the lifting platform can be achieved. When lifting a vehicle, the carriers are lifted into a working position by means of the lifting device. A leverage force acts on the lifting device in the direction of a longitudinal center axis of the lifting device and generates a torque acting towards the longitudinal center axis. This torque can be counteracted by the form-fitting plug-in connection in an area close to the ground between the central part and the respective housing of the underbody half. Additional detachable fasteners may not be necessary. This form-fit plug-in connection can be used to reinforce the floor assembly.

Eines der beiden Verbindungselemente der formschlüssigen Steckverbindung ist durch einen Haken oder einen Steg und das andere Verbindungselement durch eine Öse oder eine Öffnung ausgebildet. Dadurch sind das erste und zweite Verbindungselement beziehungsweise das eine und das andere Verbindungselement in einfacher Weise ineinander steckbar oder ineinander einhakbar, wodurch eine einfache Montage und Demontage vom Mittelteil zum Gehäuse der Bodengruppenhälfte gegeben ist. Gleichzeitig kann ohne zusätzliche Bauteile eine auf die formschlüssige Steckverbindung wirkende Zugkraft aufgenommen werden.One of the two connecting elements of the positive plug-in connection is formed by a hook or a web and the other connecting element by an eyelet or an opening. As a result, the first and second connecting element or one and the other connecting element can be plugged into one another or hooked into one another in a simple manner, as a result of which simple assembly and disassembly from the central part to the housing of the floor assembly half is provided. At the same time, a tensile force acting on the positive plug connection can be absorbed without additional components.

Eine bevorzugte Ausgestaltung der Hebebühne sieht an einer Unterseite des Mittelteils das eine oder das erste Verbindungselement vor, welches gegenüber dem Anschlussabschnitt des Mittelteils nach außen hervorsteht und an der Unterseite des Gehäuses der Bodengruppenhälfte, insbesondere der Unterseite oder Stirnseite einer Seitenfläche des Gehäuses, das zweite oder andere Verbindungselement. Diese Anordnung der formschlüssigen Steckverbindung an der Unterseite des Mittelteils und des Gehäuses der Bodengruppenhälfte ermöglicht eine erhöhte Kraftaufnahme und somit Belastbarkeit. Zusätzlich kann eine solche formschlüssige Steckverbindung ohne zusätzlichen Bauraum in die Bodengruppe der Hebebühne integriert sein.A preferred embodiment of the lifting platform provides on the underside of the middle part one or the first connecting element, which protrudes outwards in relation to the connection section of the middle part, and on the underside of the housing of the floor assembly half, in particular the underside or front side of a side surface of the housing, the second or other fastener. This arrangement of the form-fitting plug-in connection on the underside of the middle part and the housing of the floor assembly half enables increased force absorption and thus resilience. In addition, one such a form-fit plug-in connection can be integrated into the floor assembly of the lift without additional space.

Alternativ kann an einer Unterseite des Mittelteils das erste Verbindungselement vorgesehen sein, welches an den Anschlussabschnitt des Mittelteils angrenzt. An der Unterseite des Gehäuses ist das zweite Verbindungselement vorgesehen, welches gegenüber der Stirnseite des Gehäuses nach außen hervorsteht. Bei einer solchen Ausführungsform ist das Mittelteil von oben zum Gehäuse montierbar, und die Verbindungselemente greifen ineinander ein.Alternatively, the first connecting element can be provided on an underside of the central part, which is adjacent to the connection section of the central part. The second connecting element is provided on the underside of the housing and protrudes outwards relative to the end face of the housing. In such an embodiment, the central part can be fitted to the housing from above, and the connecting elements engage in one another.

Bevorzugt ist das erste Verbindungselement, welches an der Unterseite des Mittelteils angeordnet ist, als Öse oder Öffnung ausgebildet und das zweite an der Unterseite der Stirnfläche des Gehäuses angeordnete Verbindungselement durch zumindest einen Haken oder Steg ausgebildet, sodass beim Montieren des Gehäuses der Bodengruppenhälfte zum Mittelteil der zumindest eine Haken oder Steg in die zumindest eine Öse oder Öffnung eingreift. Dies kann durch ein einfaches Einsetzen von oben erfolgen. In Abhängigkeit der Anordnung, ob das erste Verbindungselement am Mittelteil oder am Gehäuse der Bodengruppenhälfte hervorstehend ausgebildet ist, kann das Einsetzen von oben durch das Mittelteil oder das Gehäuse erfolgen, um die formschlüssige Steckverbindung zu erzielen.The first connecting element, which is arranged on the underside of the central part, is preferably designed as an eyelet or opening, and the second connecting element arranged on the underside of the front face of the housing is formed as at least one hook or web, so that when the housing is installed, the underbody half can be attached to the central part of the at least one hook or bar in which at least one eyelet or opening engages. This can be done by simply inserting it from above. Depending on the arrangement, whether the first connecting element is designed to protrude on the central part or on the housing of the underbody half, it can be inserted from above through the central part or the housing in order to achieve the positive plug connection.

Bevorzugt sind die Verbindungselemente einstückig an dem Mittelteil und Gehäuse der Bodengruppenhälften integriert. Dies vereinfacht die Herstellung und reduziert die Anzahl der Bauteile für die Bodengruppe.The connecting elements are preferably integrated in one piece on the central part and housing of the floor assembly halves. This simplifies manufacture and reduces the number of components for the underbody.

Des Weiteren weist bevorzugt der stirnseitige Anschlussabschnitt am Mittelteil eine Druckfläche auf, welche mit Abstand zur formschlüssigen Steckverbindung vorgesehen ist und an einer Seitenfläche des Gehäuses der Bodengruppenhälfte angreift. Diese Druckfläche wirkt bei einer Belastung der Hebevorrichtung in einer Arbeitsposition einem zur Längsmittelachse der Hebebühne wirkenden Drehmoment entgegen. Dadurch kann dem über die Tragarme beim Heben eines Fahrzeuges auf das Mittelteil wirkenden Drehmoment oder Kippmoment zum einen durch die am Mittelteil wirkende Druckfläche und zum anderen durch die die Zugkraft aufnehmende formschlüssige Steckverbindung entgegengewirkt werden.Furthermore, the end connection section on the central part preferably has a pressure surface which is provided at a distance from the form-fitting plug connection and engages on a side surface of the housing of the underbody half. When the lifting device is loaded in a working position, this pressure surface counteracts a torque acting towards the longitudinal central axis of the lifting platform. As a result, the torque or tilting moment acting on the middle part via the support arms when lifting a vehicle on the one hand by the pressure surface acting on the middle part and on the other by the Traction absorbing positive plug connection are counteracted.

Des Weiteren greift die Druckfläche am Anschlussabschnitt des Mittelteils an einem oberen Randbereich der Seitenfläche des Gehäuses an. Dadurch kann eine vergrößerte Gegenkraft erzielt werden, indem der Hebelarm zwischen der wirkenden Druckkraft und der Zugkraft maximiert wird.Furthermore, the pressure surface on the connection section of the middle part acts on an upper edge area of the side surface of the housing. As a result, an increased counterforce can be achieved by maximizing the lever arm between the acting compressive force and the tensile force.

Des Weiteren ist bevorzugt zwischen der Seitenfläche des Gehäuses der Bodengruppenhälfte und dem Anschlussabschnitt des Mittelteils und entfernt von den Verbindungselementen zumindest ein Justierelement anordenbar, durch welches eine rechtwinklige Ausrichtung der Hebevorrichtung zum Mittelteil einstellbar ist. Die formschlüssigen Steckverbindungselemente weisen bei der Montage des Gehäuses der Bodengruppenhälfte zum Mittelteil vorzugsweise ein geringes Spiel auf. Dieser formschlüssigen Steckverbindung gegenüberliegend wird an der Anschlussstelle zumindest ein Justierelement eingebracht. Dadurch kann eine senkrechte Ausrichtung der Hebevorrichtung zum Mittelteil ermöglicht werden. Vorzugsweise sind mehrere Justierelemente vorgesehen, welche streifen- oder blättchenförmig ausgebildet sind und in unterschiedlichen dicken Abmessungen bereitgestellt werden können. Beim Zusammensetzen des Mittelteils mit dem Gehäuse der Bodengruppenhälfte kann durch die formschlüssige Steckverbindung zunächst eine Vormontageposition eingenommen werden, bei der die Hebevorrichtung geringfügig in Richtung auf die Längsmittelachse der Hebebühne geneigt ist. Durch das Positionieren des oder der Justierelemente zwischen der Druckfläche des Mittelteils und der Seitenfläche des Gehäuses kann eine Ausrichtung in eine vertikale Position zum Mittelteil ermöglicht sein und gleichzeitig das in der Vormontageposition gegebenenfalls bestehende geringe Spiel eliminiert werden.Furthermore, at least one adjusting element can preferably be arranged between the side surface of the housing of the underbody half and the connection section of the middle part and away from the connecting elements, by means of which a right-angled alignment of the lifting device to the middle part can be adjusted. The form-fitting plug-in connection elements preferably have a small amount of play when the housing of the floor assembly half is assembled with the central part. At least one adjusting element is introduced at the connection point opposite this form-fitting plug-in connection. This allows the lifting device to be aligned perpendicularly to the central part. A plurality of adjusting elements are preferably provided, which are designed in the form of strips or flakes and can be provided in different thickness dimensions. When assembling the central part with the housing of the floor assembly half, a pre-assembly position can first be assumed by the positive plug connection, in which the lifting device is slightly inclined in the direction of the longitudinal center axis of the lifting platform. By positioning the adjusting element or elements between the pressure surface of the central part and the side surface of the housing, alignment in a vertical position relative to the central part can be made possible and at the same time the slight play that may exist in the pre-assembly position can be eliminated.

Des Weiteren ist bevorzugt das Mittelteil jeweils mit dem Gehäuse der Bodengruppenhälfte durch zumindest ein lösbares Befestigungsmittel zueinander gesichert. Dieses zumindest eine lösbare Befestigungsmittel ist bevorzugt entfernt von der formschlüssigen Steckverbindung an der Anschlussstelle vorgesehen. Insbesondere ist das zumindest eine lösbare Befestigungsmittel im Bereich der Druckfläche des Mittelteils vorgesehen. Dieses zumindest eine lösbare Befestigungsmittel wird nach dem Ausrichten der Hebevorrichtung angebracht, um das Mittelteil an dem jeweiligen Gehäuse der Bodengruppenhälfte zu fixieren. Gleichzeitig sind dadurch das oder die Justierelemente, welche in der Anschlussstelle eingebracht sind, fixiert. Somit kann die ausgerichtete Position der Hebevorrichtung zur Bodengruppe auch während einer Verfahrbewegung der verfahrbaren Hebebühne aufrechterhalten bleiben. Das zumindest eine lösbare Befestigungsmittel dient als Zusammenbausicherung zwischen dem Mittelteil und dem Gehäuse der Bodengruppenhälfte und nicht zur Kraftaufnahme oder Kraftübertragung.Furthermore, the central part is preferably secured to each other with the housing of the floor assembly half by at least one detachable fastening means. This at least one detachable fastener is preferably provided at a distance from the positive plug connection at the connection point. In particular, the at least one detachable fastening means is provided in the area of the pressure surface of the central part. This at least one detachable fastening means is attached after the lifting device has been aligned, in order to fix the middle part to the respective housing of the underbody half. At the same time, this means that the adjusting element or elements that are introduced into the connection point are fixed. In this way, the aligned position of the lifting device relative to the base assembly can also be maintained during a movement of the movable lifting platform. The at least one detachable fastening means serves to secure the assembly between the central part and the housing of the underbody half and not to absorb or transmit force.

Des Weiteren ist die Hebevorrichtung bevorzugt als Parallelogrammführungsvorrichtung oder Scherenführungsvorrichtung, insbesondere als Halbschere, Vollschere oder Doppelschere, ausgebildet, welche zumindest einen Lastarm und einen Führungsarm umfasst, die an ihren der Bodengruppenhälfte gegenüberliegenden freien Enden den Träger aufnehmen. In Abhängigkeit des Einsatzfalles kann die Hebevorrichtung ausgewählt werden.Furthermore, the lifting device is preferably designed as a parallelogram guide device or scissors guide device, in particular as half scissors, full scissors or double scissors, which comprises at least one load arm and one guide arm, which receive the carrier at their free ends opposite the half of the base assembly. Depending on the application, the lifting device can be selected.

Des Weiteren ist bevorzugt zumindest ein Antrieb in oder an der zumindest einen Bodengruppenhälfte vorgesehen. Die Anzahl der Antriebe und/oder die Positionierung der Antriebe können wiederum in Abhängigkeit von der maximal zu tragenden Last und/oder der Baugröße der Hebebühne sein.Furthermore, at least one drive is preferably provided in or on the at least one half of the underbody. The number of drives and/or the positioning of the drives can in turn depend on the maximum load to be carried and/or the size of the lifting platform.

Die Figur 1 zeigt eine perspektivische Ansicht einer erfindungsgemäßen Hebebühne 11. Diese Hebebühne 11 umfasst eine Bodengruppe 12, welche zwei Bodengruppenhälften 14 und ein dazwischen angeordnetes Mittelteil 15 umfasst. Durch das Mittelteil 15 sind die Bodengruppenhälften 14 vorzugsweise parallel zueinander beabstandet und ausgerichtet. Durch die Bodengruppenhälften 14 und das Mittelteil 15 wird eine U-förmige Bodengruppe 12 gebildet. Der offene Bereich stellt einen Einfahrbereich in einen Arbeitsraum 50 für ein Fahrzeug dar, welches so lange einfährt, bis dieses nahe dem Mittelteil 15 positioniert ist. Die Einfahrrichtung ist gemäß Pfeil 17 in der Draufsicht auf die Hebebühne 11 in Figur 2 dargestellt. Die Einfahrrichtung liegt im Bereich einer Längsmittelachse 18 der Hebebühne 11. Die Längsmittelachse 18 erstreckt sich parallel zwischen den beiden Bodengruppenhälften 14 und ist mittig dazu angeordnet. Zumindest zwischen den beiden Bodengruppenhälften 14 ist der Arbeitsraum 50 gebildet.The figure 1 shows a perspective view of a lifting platform 11 according to the invention. This lifting platform 11 comprises a floor assembly 12 which comprises two floor assembly halves 14 and a central part 15 arranged between them. By means of the middle part 15, the floor assembly halves 14 are preferably spaced apart and aligned parallel to one another. A U-shaped floor assembly 12 is formed by the floor assembly halves 14 and the central part 15 . The open area represents an entry area into a working space 50 for a vehicle, which drives in until it is positioned near the central part 15 . The retraction direction is according to arrow 17 in the top view of the lifting platform 11 in figure 2 shown. The retraction direction is in the area of a longitudinal center axis 18 of the lifting platform 11. The longitudinal center axis 18 extends parallel between the two floor assembly halves 14 and is arranged centrally thereto. At least the working space 50 is formed between the two floor assembly halves 14 .

Jede Bodengruppenhälfte 14 umfasst ein Gehäuse 21, innerhalb welcher ein schematisch dargestellter Antrieb 22 vorgesehen ist. Des Weiteren nimmt jede Bodengruppenhälfte 14 eine Hebevorrichtung 24 auf. Im Ausführungsbeispiel ist diese Hebevorrichtung 24 als eine Parallelogrammführungsvorrichtung ausgebildet. Der zumindest eine Antrieb 22 hebt und senkt die Hebevorrichtung 24. Diese Hebevorrichtung 24 umfasst einen Lastarm 25, der um eine erste Schwenkachse 26 schwenkbar ist. Des Weiteren umfasst die Hebevorrichtung 24 einen Führungsarm 27, der um eine zweite Schwenkachse 28 schwenkbar ist, die zur ersten Schwenkachse 26 beabstandet ist. Beide Schwenkachsen 26, 28 sind an dem Gehäuse 21 gelagert.Each underbody half 14 includes a housing 21 within which a drive 22, shown schematically, is provided. Furthermore, each underbody half 14 accommodates a lifting device 24 . In the exemplary embodiment, this lifting device 24 is designed as a parallelogram guide device. The at least one drive 22 raises and lowers the lifting device 24. This lifting device 24 comprises a load arm 25 which can be pivoted about a first pivot axis 26. Furthermore, the lifting device 24 includes a guide arm 27 which can be pivoted about a second pivot axis 28 which is spaced apart from the first pivot axis 26 . Both pivot axes 26, 28 are mounted on the housing 21.

Die Hebevorrichtung 24 weist an einem zum Gehäuse 21 entfernten Endbereich einen Träger 31 auf, der durch die Hebevorrichtung 24 während dem Heben und Senken der Hebevorrichtung 24 horizontal ausgerichtet bleibt. In Figur 1 sind die Hebevorrichtungen 24 in einer Arbeitsposition 32 vorgesehen. Eine solche Arbeitsposition 32 kann einer Überkopfhöhe entsprechen. In einer Nichtgebrauchsposition sind die Hebevorrichtungen 24 nahe dem Boden ausgerichtet oder auf dem Boden aufliegend positioniert.The lifting device 24 has at an end region remote from the housing 21 a carrier 31 which remains horizontally aligned by the lifting device 24 during the raising and lowering of the lifting device 24 . In figure 1 the lifting devices 24 are provided in a working position 32 . Such a working position 32 can correspond to an overhead height. In a non-use position, the jacks 24 are aligned near the ground or positioned resting on the ground.

Jeder Träger 31 nimmt zumindest einen Tragarm 34 auf. Vorzugsweise sind jeweils zwei Tragarme 34 an dem Träger 31 vorgesehen. Diese Tragarme 34 sind um jeweils eine Lagerachse 35, 36 schwenkbar gelagert. Die Tragarme 34 können gleich lang ausgebildet sein. Alternativ kann der zum Einfahrbereich weisende, hintere Tragarm länger ausgebildet sein als der zum Mittelteil 15 weisende, insbesondere vordere Tragarm 34. Die Tragarme 34 sind bevorzugt als Teleskoptragarme ausgebildet.Each carrier 31 accommodates at least one support arm 34 . Two support arms 34 are preferably provided on the support 31 in each case. These support arms 34 are each pivoted about a bearing axis 35, 36. The support arms 34 can be of the same length. Alternatively, the rear support arm pointing towards the entry area can be made longer than the, in particular front, support arm 34 pointing towards the central part 15. The support arms 34 are preferably designed as telescopic support arms.

Die Hebebühne 11 ist bevorzugt als eine verfahrbare Hebebühne 11 ausgebildet. Jede Bodenbaugruppenhälfte 14 weist bevorzugt an einem vom Mittelteil 15 entfernten Ende eine Laufrolle 38 auf, die Teil eines Fahrwerkes ist. Des Weiteren kann eine nicht näher dargestellte Deichsel in einem mittleren Bereich am Mittelteil 15 befestigbar sein, sodass nach Anheben des Mittelteils die Hebebühne 11 sich auf einem Laufrad der Deichsel und den beiden Laufrollen 38 abstützt. Dadurch ist die Hebebühne 11 mobil und kann am jeweiligen Gebrauchsort verfahrbar sein. Nach dem Abnehmen der Deichsel ist diese Hebebühne 11 ortsfest und liegt auf dem Boden auf.The lifting platform 11 is preferably designed as a movable lifting platform 11 . Each floor assembly half 14 preferably has a caster 38 at an end remote from the center portion 15 which is part of a landing gear. Furthermore, a drawbar, not shown in detail be fastened in a middle area on the middle part 15, so that after the middle part has been raised, the lifting platform 11 is supported on a running wheel of the drawbar and the two running rollers 38. As a result, the lifting platform 11 is mobile and can be moved at the respective place of use. After removing the drawbar, this lift 11 is stationary and rests on the ground.

Alternativ kann die Hebebühne 11 auch als eine ortsfeste Hebebühne ausgebildet sein. In diesem Fall können die Laufrollen 38 entfallen.Alternatively, the lifting platform 11 can also be designed as a stationary lifting platform. In this case, the rollers 38 can be omitted.

Zur Ansteuerung der Hebebühne 11 aus einer Nichtgebrauchsposition in eine Arbeitsposition 32 ist eine Steuerung 41 vorgesehen, welche beispielsweise an einer der beiden Bodengruppenhälften 14 angeordnet ist. Diese Steuerung 41 kann ein Steuersignal an den oder die jeweiligen Antriebe 22 ausgeben. Der Antrieb 22 kann ein Hydraulikzylinder sein, der elektrisch ansteuerbar ist. Bevorzugt ist in jedem Gehäuse 21 der Bodengruppenhälfte 14 ein Antrieb 22 vorgesehen. Die Steuerung 41 umfasst Überwachungssensoren zur Synchronisation der Anhebe- und Absenkbewegung der jeweiligen Hebevorrichtung 24. Von der Steuerung 41 können Steuerleitungen einerseits in die unmittelbar zugeordnete Bodengruppenhälfte 14 geführt werden. Andererseits können Steuerleitungen innerhalb des Mittelteils 15 zur gegenüberliegenden Bodengruppenhälfte 14 geführt werden.To control the lifting platform 11 from a non-use position to a working position 32, a controller 41 is provided, which is arranged, for example, on one of the two floor assembly halves 14. This controller 41 can output a control signal to the respective drive or drives 22 . The drive 22 can be a hydraulic cylinder that can be controlled electrically. A drive 22 is preferably provided in each housing 21 of the underbody half 14 . The controller 41 includes monitoring sensors for synchronizing the raising and lowering movement of the respective lifting device 24. From the controller 41, control lines can be routed into the directly assigned half 14 of the floor assembly. On the other hand, control lines can be routed within the central part 15 to the opposite floor assembly half 14 .

Die Bodengruppe 12 umfasst eine erste und zweite Anschlussstelle 45, 46, wodurch das Mittelteil 15 zur jeweiligen Bodengruppenhälfte 14 montierbar und demontierbar ist. Über diese Anschlussstelle 45, 46 werden die wirkenden Kräfte beim Heben des Fahrzeugs von der Bodengruppenhälfte 14 in das Mittelteil 15 eingeleitet. In Figur 3 ist beispielsweise die Kraft F1 dargestellt, welche auf die Tragarme 34 wirkt. Diese Kraft F1 symbolisiert ein angehobenes Fahrzeug in einer Arbeitsposition 32. Durch die Schwenkposition des Tragarms 34 zum Träger 31 wird die Länge eines Hebelarms L1 bestimmt. Daraus resultiert ein Drehmoment M1 beziehungsweise ein Kippmoment der Hebevorrichtung 24 in Richtung zur Längsmittelachse 16, welches durch den Lastarm L1 und die Kraft F1 erzeugt wird. Die Anschlussstelle 45 wirkt diesem Moment M1 mit einer Druckkraft F2 mit dem Hebelarm L2 über das Gehäuse 21 der Bodengruppenhälfte 14 auf den Anschlussabschnitt 48 des Mittelteils 15 entgegen. Analoges gilt für die Anschlussstelle 46.The floor assembly 12 includes a first and second connection point 45, 46, as a result of which the central part 15 can be assembled and disassembled with respect to the respective floor assembly half 14. The forces acting when the vehicle is lifted are introduced from the underbody half 14 into the central part 15 via this connection point 45, 46. In figure 3 For example, the force F1 is shown, which acts on the support arms 34. This force F1 symbolizes a raised vehicle in a working position 32. The pivoting position of the support arm 34 relative to the support 31 determines the length of a lever arm L1. This results in a torque M1 or a tilting moment of the lifting device 24 in the direction of the longitudinal center axis 16, which is generated by the load arm L1 and the force F1. Connection point 45 works This moment M1 counteracts this moment M1 with a pressure force F2 with the lever arm L2 via the housing 21 of the floor assembly half 14 on the connection section 48 of the central part 15 . The same applies to connection point 46.

In Figur 4 ist eine perspektivische Ansicht von oben auf die Anschlussstelle 45 dargestellt. Die Figur 5 zeigt eine perspektivische Ansicht der Anschlussstelle 45 von unten. Diese Anschlussstelle 45 ist identisch mit der Anschlussstelle 46 ausgebildet.In figure 4 a perspective view of the connection point 45 is shown from above. The figure 5 shows a perspective view of the connection point 45 from below. This connection point 45 is identical to the connection point 46 .

Die Anschlussstelle umfasst am jeweiligen Endbereich einen Anschlussabschnitt 48, der an einer Seitenfläche 49 des Gehäuses 21 angreift. Zur Anbindung des Mittelteils 12 zum Gehäuse 21 ist eine formschlüssige Steckverbindung 51 vorgesehen. Diese Steckverbindung 51 ist bevorzugt zur Aufnahme der Zugkraft F3 ausgebildet. Diese formschlüssige Steckverbindung 51 umfasst ein erstes Verbindungselement 52 sowie ein zweites Verbindungselement 53, die ineinander steckbar sind und formschlüssig ineinander greifen. Das erste Verbindungselement 52 ist beispielsweise durch Öffnungen 55, insbesondere eine geschlossene Öffnung, ausgebildet. Das zweite Verbindungselement 53 ist beispielsweise durch Stege 56 ausgebildet. Dabei sind die Öffnungen 55 geringfügig größer als die Stege 56, sodass diese in die Öffnungen 55 beim Einsetzen leicht ineinander eingreifen. Die Öffnungen 55 sind vorzugsweise abgeflacht, wobei die Abflachung 57 rechtwinklig zur Zugkraftrichtung F3 ausgerichtet ist und der Kraftwirkungsrichtung F3 entgegenwirkt. An dieser Abflachung 57 liegen die Stege 56 an.The connection point comprises a connection section 48 at the respective end area, which engages on a side surface 49 of the housing 21 . A positive plug-in connection 51 is provided for connecting the central part 12 to the housing 21 . This plug-in connection 51 is preferably designed to absorb the tensile force F3. This positive plug-in connection 51 comprises a first connecting element 52 and a second connecting element 53, which can be plugged into one another and engage in one another in a form-fitting manner. The first connecting element 52 is formed, for example, by openings 55, in particular a closed opening. The second connecting element 53 is formed by webs 56, for example. The openings 55 are slightly larger than the webs 56 so that they easily engage in the openings 55 when inserted into one another. The openings 55 are preferably flattened, with the flattening 57 being aligned at right angles to the direction of tensile force F3 and counteracting the direction of action of the force F3. The webs 56 rest against this flattening 57 .

Es versteht sich, dass die Ausgestaltung des ersten und zweiten Verbindungselementes 52, 53 auch vertauscht vorgesehen sein können.It goes without saying that the design of the first and second connecting elements 52, 53 can also be reversed.

Die formschlüssige Steckverbindung 51 ist in einem bodennahen Bereich an der Anschlussstelle 45 vorgesehen. Beispielsweise ist das erste Verbindungselement 52 in einer Bodenplatte 59 des Mittelteils 15 integriert. Die Bodenplatte 59 erstreckt sich über den Anschlussabschnitt 48 hinaus in Richtung auf das Gehäuse 21. An einer unteren Stirnseite 61 der Seitenfläche 49 des Gehäuses 21 sind bevorzugt die als Stege 56 ausgebildeten zweiten Verbindungselemente 53 vorgesehen. Dadurch greift durch ein einfaches Aufsetzen des Gehäuses 21 auf die Bodenplatte 59 das zweite Verbindungselement 53 in das erste Verbindungselement 52 ein und ist formschlüssig angeordnet.The form-fitting plug-in connection 51 is provided in an area close to the ground at the connection point 45 . For example, the first connecting element 52 is integrated in a base plate 59 of the central part 15 . The base plate 59 extends beyond the connection section 48 in the direction of the housing 21. The second connecting elements 53 designed as webs 56 are preferably provided on a lower end face 61 of the side surface 49 of the housing 21. Through this By simply placing the housing 21 on the base plate 59, the second connecting element 53 engages in the first connecting element 52 and is arranged in a form-fitting manner.

Der Anschlussabschnitt 48 des Mittelteils 12 erstreckt sich vorzugsweise von einer Bodenplatte 59 aus vertikal nach oben, wobei die Höhe des Anschlussabschnitts 48 der Höhe der Seitenfläche 49 des Gehäuses 21 entspricht oder geringfügig niedriger ist. Zur Aussteifung des Anschlussabschnitts 48 sind Verstärkungsrippen 63 vorgesehen, welche sich einerseits an einer Oberseite 64 des Mittelteils 15 und andererseits an dem frei gegenüber dem Mittelteil 15 herausragenden Anschlussabschnitt 48 abstützen.The connection section 48 of the central part 12 preferably extends vertically upwards from a base plate 59, the height of the connection section 48 corresponding to the height of the side surface 49 of the housing 21 or being slightly lower. Reinforcing ribs 63 are provided to stiffen the connection section 48 , which are supported on the one hand on an upper side 64 of the middle part 15 and on the other hand on the connection section 48 protruding freely from the middle part 15 .

In Figur 6 ist eine Ansicht auf den Anschlussabschnitt 48 des Mittelteils 15 dargestellt. Der Anschlussabschnitt 48 ist als ebene Anlagefläche ausgebildet, welche an der Seitenfläche 49 anliegt. Die Bodenplatte 59 ragt bereichsweise gegenüber dem Anschlussabschnitt 48 nach außen vor, wobei die ersten Verbindungselemente 52 im unteren Eckbereich zwischen der Bodenplatte 59 und dem Anschlussabschnitt 48 gebildet sind.In figure 6 a view of the connection section 48 of the central part 15 is shown. The connection section 48 is designed as a flat contact surface which bears against the side surface 49 . The base plate 59 protrudes outwards in some areas in relation to the connection section 48 , the first connecting elements 52 being formed in the lower corner area between the base plate 59 and the connection section 48 .

Im oberen Bereich des Anschlussabschnitts 48 ist eine Druckfläche 65 ausgebildet, welche die Kraft F2 aufnimmt.In the upper area of the connection section 48 there is a pressure surface 65 which absorbs the force F2.
