Description

Kraftfahrzeug-Hebe- und Schwen vorπchtunq Motor vehicle lifting and swiveling
Die Erfmdunq betrifft eine Hub- und Schwenkvorrichtung f ein Kraftfahrzeug mit einer bodenseitig abgestützten Hubvorrichtung, die einen, an dem Kraftfahrzeug seitlich unten fixierbaren, vertikal verbringbaren Hubarm tragt, d von einer, in beliebigen Hubstellungen arretierbaren, Antriebsvorrichtung betätigbar ist.The Erfmdunq relates to a lifting and swiveling device f a motor vehicle with a bottom-side lifting device which carries a vertically movable lifting arm which can be fixed laterally at the bottom of the motor vehicle and which can be actuated by a drive device which can be locked in any desired lifting positions.
Es ist bekannt, mit einem vertikal positionierbaren Hubar der einerseits am Boden abgestützt ist, an einem Kraftfahrzeug seitlich anzugreifen und damit dieses durch Betätigung des Hubarmes anzuheben oder abzusenken. Hierbe ist jedoch die einseitige Anhebung begrenzt, da eine dadu auftretende Verschwenkung des Fahrzeuges die Kippgrenze nicht erreichen darf. Deshalb sind Montagevorgange unter Fahrzeug in angehobenen Zustand nur beschränkt aus ührbar sofern keine Montagegrube vorhanden ist.It is known, with a vertically positionable hub which is supported on the ground, to engage laterally on a motor vehicle and thus raise or lower it by actuating the lifting arm. Here, however, the one-sided lifting is limited, as a resultant swiveling of the vehicle must not reach the tipping limit. For this reason, assembly processes under the vehicle in the raised state can only be carried out to a limited extent if there is no assembly pit.
Es ist Aufgabe der Erfindung, eine Hebe- und Schwenkvorrichtung für Kraftfahrzeuge zu offenbaren, die einfach aufgebaut ist und ein Schwenken des Fahrzeuges um annähernd 90° ohne Kippgefahr ermöglicht.It is an object of the invention to disclose a lifting and swiveling device for motor vehicles, which is of simple construction and enables the vehicle to be swiveled by approximately 90 ° without the risk of tipping over.
Die Lösung besteht darin, daß die Hubvorrichtung eine Hubhöhe aufweist, die mindestens einer maximalen Fahrzeugbreite entspricht, und ein Paar Schwenkkufen aufweist, die der Hubvorrichtung gegenüberliegend an dem Kraftfahrzeug anzuordnen sind und die jeweils aus einem e 1 /4-kreιs örmigen Teilabschnitt mit tanqentialen Auslaufe bestehen, an dem kreisinnenseitig Befestigungs- und/oder Aufnahmevorrichtungen gehalten sind, die an traqfähige Tei des Kraftfahrzeuges anzuschließen sind, und deren Auslaufe sich im montierten Zustand seitlich des Kraftfahrzeuges na oben über dessen Schwerpunkt hinaus erstrecken.The solution is that the lifting device has a lifting height which corresponds to at least a maximum vehicle width, and has a pair of swivel runners which are to be arranged opposite the lifting device on the motor vehicle and which each have an e 1/4 circular section with tanqential spouts exist on the inside of the circle fastening and / or receiving devices are held, which are to be connected to traq capable parts of the motor vehicle, and their outlets extend na above the center of gravity in the assembled state to the side of the motor vehicle.

Die Befestigung der Vorrichtung erfolgt vorteilhaft an den Radaufnahmen, da die Radaufhängungen für die Belastung, di beim Verschwenken des Fahrzeuges auftritt, ausgelegt sind. Die Befestigungen an den Radaufnahmen sind vorteilhaft als passende verschraubbare Scheiben ausgeführt, die mit den Schwenkkufen lösbar verbunden sind.The device is advantageously attached to the wheel receptacles, since the wheel suspensions are designed for the load that occurs when the vehicle is pivoted. The fastenings on the wheel holders are advantageously designed as suitable screwable disks that are detachably connected to the swivel skids.
Die Hubvorrichtung, die vorzugsweise als Hubspindeltrieb ausgestaltet ist, ist untenendig vorteilhaft auf einem Rollenpaar abgestützt, das mittels eines Zugverbinders am Ende der Schwenkkufen angeschlossen ist, so daß beim Anheb und Verschwenken des Fahrzeuges die Hubvorrichtung stets n leicht qeneigt ist und ihr Unterteil beim Schwenken an das Fahrzeug herangezogen wird, wodurch der Arbeitsraum zu der Fahrzeugunterseite relativ frei ist, die Biegekräfte auf d Hubvorrichtung gering bleiben, und auf das Fahrzeug nur geringe seitliche Schubkräfte ausgeübt werden.The lifting device, which is preferably designed as a lifting spindle drive, is advantageously supported at the bottom on a pair of rollers, which is connected by means of a pull connector at the end of the swivel skids, so that when lifting and swiveling the vehicle, the lifting device is always slightly inclined and its lower part is pivoted the vehicle is used, so that the working space to the underside of the vehicle is relatively free, the bending forces on the lifting device remain low, and only slight lateral thrust forces are exerted on the vehicle.

Die Hubvorrichtung kann ein Hydraulikheber oder ein Pneumatikheber sein falls geeignete Versorgungsaggregate dafür verfügbar sind. Vorzugsweise wird eine einfache Hubspindel verwandt, die obenendig über ein Kegelradgetri mit einer Rastklinkensperrvorrichtung und einer Kurbel od vorzugsweise mit einem Motor über ein selbsthemmendes Getriebe zu betätigen ist. In einer bevorzugten Ausführun ist der Anschluß zwischen dem Getriebe und dem Motor lösb und der Motoranschluß zu einer handelsüblichen Bohrmaschi passend ausgestaltet, so daß diese dort angeklemmt werden kann.The lifting device can be a hydraulic jack or a pneumatic jack if suitable supply units are available for it. A simple lifting spindle is preferably used, which is to be actuated at the top end via a bevel gear transmission with a latch locking device and a crank or preferably with a motor via a self-locking transmission. In a preferred embodiment, the connection between the gear and the motor is detachable and the motor connection is designed to fit a commercially available drilling machine, so that it can be clamped there.
Um die Rückkippsicherheit zu erhöhen, ist zwischen den Schwenkkufen jeweils eine Stütze schwenkbar angeordnet, d in der voll geschwenkten Lage vertikal steht und zusatzli zur arretierten Hubvorrichtung ein Rückschwenken des Fahrzeuges verhindert.In order to increase the safety against tipping back, a support is pivotably arranged between the swivel runners, d is vertical in the fully swiveled position and, in addition to the locked lifting device, prevents the vehicle from swiveling back.
Die vordere und hintere Schwenkkufe sind durch eiene einsteckbare Verbindungsstange endseitig so verbunden, da der nach unten zu schwenkende Seitenbereich des Kraftfahrzeuges beim Schwenken geschützt ist und umgekehr Personen und Gegenstände beim Schwenken von dem Seitenbereich ferngehalten werden. Die Verbindungsstange in einer derartigen Höhenlage angeordnet, daß der Fahrzeugschwerpunkt wesentlich darunter liegt, so daß im gekippten Zustand das Fahrzeug darüber nicht unbeabsichti weiterschwenkt und auf das Dach kippt.The front and rear swivel skids are connected at the ends by a plug-in connecting rod so that the side region of the motor vehicle to be swiveled down is protected when swiveling and, conversely, people and objects are kept away from the side region when swiveling. The connecting rod is arranged at an altitude such that the center of gravity of the vehicle lies significantly below it, so that in the tilted state the vehicle does not inadvertently swivel over it and tilts onto the roof.
Die Schwenkkufen sind jeweils aus einem Paar von gebogene Rohren gebildet, die durch Querstreben miteinander verschweißt sind und einen gerichteten Halt für die dazwischen angeordneten Befestigungsplatten zu den Radaufnahmen geben. Hierdurch ist die gesamt Vorrichtung stabil und trotzdem leicht, und demontiert benötigt sie wenig Platz. Eine vorteilhafte Ausgestaltung ist in den Figuren 1 bis 4 dargestellt.The swivel runners are each formed from a pair of curved tubes, which are welded to one another by cross struts and provide a directed hold for the fastening plates arranged in between to the wheel holders. As a result, the entire device is stable and still light, and when disassembled it takes up little space. An advantageous embodiment is shown in Figures 1 to 4.

Die Befestigungsplatte (52) ist mit der hinteren Radaufna (12) verschraubt.Fig. 3 shows the same vehicle pivot position, with the viewing angle directed more towards the underside of the vehicle. The paired arrangement of the skid tubes (4, 4A), the tension strut (31, 31B), the wheels (30) and the lifting device (2) lying in the center thereof can thus be clearly seen. The central position of the support (7) between the runners (4, 4A), which is supported at the top on a cross strut (40), is visible here. Fig. 4 shows the device in a side perspective after de assembly. The rear pair of runners (5, 5A) is similar to the front pair of runners (4, 4A) and is also connected to one another with cross struts (50) and a fastening device (51). A fastening plate (52) is also held on the fastening device (by means of brackets and bolts with spring locking pins). The fastening plate (52) is screwed to the rear wheel socket (12).
Die Hubvorrichtung kann an jeder Ecke des Fahrzeuges angesetzt werden, so daß sie den optimalen ungehinderten Zugang zur Fahrzeugunterseite ermöglicht.The lifting device can be attached to every corner of the vehicle so that it enables optimal unimpeded access to the underside of the vehicle.
Statt an den Radaufnahmen läßt sich der Hubarm auch an de üblichen Heberaufnahmeösen des Chassisrahmens ansetzen, u auch die Befestigungsvorrichtung der Schwenkkufen lassen sich statt mit den Schraubplatten auch mit Aufnahmewinkel bestücken, die am Chassisrahmen oder an einem anderen tragfahgien Bauteil, z.B. der Motoraufhängung , untergeset und seitlich angesetzt werden. In diesen Fällen kann die Demontage der entsprechenden Räder entfallen. Instead of the wheel mounts, the lifting arm can also be attached to the usual lifting eyelet eyelets of the chassis frame, u the fastening device of the swivel skids can also be equipped with mounting brackets instead of the screw plates, which are attached to the chassis frame or to another load-bearing component, e.g. the engine mounting, placed underneath and attached to the side. In these cases, the disassembly of the corresponding wheels can be omitted.
