Abstract

PCT No. PCT/DE96/00633 Sec. 371 Date Feb. 11, 1998 Sec. 102(e) Date Feb. 11, 1998 PCT Filed Apr. 3, 1996 PCT Pub. No. WO96/31321 PCT Pub. Date Oct. 10, 1996The present invention relates to a hydraulic platform lift, in particular a motorcycle platform lift, comprising a parallelogram chassis in which on one of the two parallel lifting arms a hydraulic cylinder, supported on the sub-frame, is articulated. The task of the invention is providing such a platform lift which has a substantially better intrinsic weight/lifting-force ratio than the comparable platform lifts known from prior art. This task is solved according to the invention by means of a platform lift of the above cited type thereby that the hydraulic cylinder (1) engages the lifting arm (4) at an articulation point (8) beneath the pivot axis (7) which for this purpose comprises in this region a projection (9) directed downwardly in order to make available a favorable lever arm (15) for the force transmission of the hydraulic cylinder (1), and that a tie (5) is provided connecting the support point (2) of the hydraulic cylinder (1) on the sub-frame (3) with the lifting arm (4), the articulation point (6) of which on the lifting arm (4) is coaxial with its pivot axis (7).

Description

Die vorliegende Erfindung betrifft eine hydraulische Hebebühne, insbesondere eine Motorradhebebühne, welche ein Parallelogrammchassis aufweist, wobei an einem der beiden parallelen Hubarme ein am Unterchassis abgestützter Hydraulikzylinder angelenkt ist, der an einen Anlenkpunkt unterhalb der Schwenkachse des einen Hubarms am Unterchassis an den einen Hubarm angreift, welcher dazu in diesem Bereich eine nach unten gerichtete Auskragung aufweist, um einen günstigen Hebelarm zwischen dem Anlenkpunkt und der Schwenkachse des einen Hubarms für die Kraftübertragung des Hydraulikzylinders zur Verfügung zu stellen.The present invention relates to a hydraulic lifting platform, in particular a motorcycle lifting platform, which has a parallelogram chassis has, being on one of the two parallel lifting arms a hydraulic cylinder supported on the lower chassis is at a pivot point below the pivot axis of the a lifting arm on the lower chassis attacks one lifting arm, which a downward projection in this area has a favorable lever arm between the pivot point and the pivot axis of a lifting arm for power transmission of the hydraulic cylinder.

Eine aus dem Stand der Technik bekannte Hebebühne ist in den Fig. 2.1 bis 2.3 der beigefügten Zeichnung dargestellt. Die Druckkraft des Hydraulikzylinders, die bei Hebebühnen der gattungsgemäßen Art bis zu ca. 3 t betragen kann, wird hier vollständig in das Unterchassis abgeleitet. Dieses sowie auch der betroffene Hubarm müssen dementsprechend stark dimensioniert werden, um diese Kräfte aufnehmen zu können. Das führt zu einem ungünstigen Eigengewicht/Hubkraft-Verhältnis, wodurch diese Bühnen in der Regel als stationäre Einrichtungen Werkstätten vorbehalten sind.A lift known from the prior art is in the Fig. 2.1 to 2.3 of the accompanying drawing. The Compressive force of the hydraulic cylinder, which is of the generic type for lifting platforms Type can be up to approx. 3 t, is complete here derived into the lower chassis. This as well as the affected one The lifting arm must be dimensioned accordingly, to be able to absorb these forces. This leads to an unfavorable Dead weight / lifting power ratio, which makes these platforms usually reserved as stationary facilities for workshops are.

Weiterhin nachteilig auf das Eigengewicht/Hubkraft-Verhältnis wirkt sich auch aus, daß der zweite Hubarm über das Oberchassis von dem durch den Hydraulikzylinder beaufschlagten Hubarm mitgezogen wird. Diese Konstruktion würde bei großen zu hebenden Lasten und aus Gründen der Eigengewichtsreduzierung schwach dimensionierten Bauteilen der Hebebühne zwangsläufig zu Klemmungen des Parallelogrammchassis führen. Still disadvantageous on the weight / lifting ratio also affects that the second lift arm over the upper chassis pulled by the lifting arm acted upon by the hydraulic cylinder becomes. This design would handle large loads and weakly dimensioned for reasons of weight reduction Components of the lift inevitably to clamp the Guide parallelogram chassis.

Aus EP 0 047 976 A2 und US-PS 2,920,773 sind Hubvorrichtungen bekannt, bei denen die am Unterchassis abgestützten Hydraulikzylinder an einen Anlenkpunkt unterhalb der Schwenkachse des einen Hubarms am Unterchassis an diesen angreifen. Dazu weist dieser Hubarm in diesem Bereich eine nach unten gerichtete Auskragung auf. Durch diese Auskragung ist ein sehr günstiger Hebelarm für die Übertragung der Hubkraft des Hydraulikzylinders auf den Hubarm gegeben.Lifting devices are known from EP 0 047 976 A2 and US Pat. No. 2,920,773 known in which the hydraulic cylinders supported on the lower chassis to a pivot point below the pivot axis of one Grip the lifting arms on the lower chassis. This points to this Lift arm in this area a downward projection on. This cantilever is a very cheap lever arm for the transmission of the lifting force of the hydraulic cylinder to the lifting arm given.

Bekannte Hebebühnen der hier in Frage kommenden Art haben daher aus den oben genannten Gründen ein Eigengewicht, das zwischen ca. 140 bis über 200 kg liegt, wobei das Hebevermögen etwa bei 400 kg liegt.Known lifts of the type in question here have therefore for the reasons mentioned above, a dead weight between approx. 140 to over 200 kg, the lifting capacity being about 400 kg.

Aufgabe der vorliegenden Erfindung ist es, eine hydraulische Hebebühne, insbesondere eine Motorradhebebühne, der gattungsgemäßen Art zur Verfügung zu stellen, die ein wesentlich besseres Eigengewicht/Hubkraft-Verhältnis aufweist als die aus dem Stand der Technik bekannten, vergleichbaren Hebebühnen.The object of the present invention is a hydraulic Lifting platform, in particular a motorcycle lifting platform, of the generic type Kind of providing a much better Tare weight / lifting power ratio than that from standing comparable lifting platforms known in the art.

Diese Aufgabe wird erfindungsgemäß mittels einer gattungsgemäßen Hebebühne dadurch gelöst, daß eine den Abstützpunkt des Hydraulikzylinders am Unterchassis mit dem Hubarm verbindende Zugstrebenanordnung vorgesehen ist, deren Anlenkpunkt am Hubarm mit dessen Schwenkachse koaxial liegt.This object is achieved by means of a generic Lifted in that one of the support point of the Hydraulic cylinder connecting the lower chassis to the lifting arm Tension strut arrangement is provided, the articulation point on the lifting arm is coaxial with its pivot axis.

Um den Ausgangspunkt der Hubkraft des Hydraulikzylinders im Unterchassis zu entlasten, und um eine Umlenkung von horizontaler in vertikale Bewegung zu ermöglichen, ist erfindungsgemäß eine Zugstrebenanordnung von der Linie der Schwenkachse des Hubarmes zum Ausgang der Hubkraft am Zylinderfuß vorgesehen. Die Überlagerung dieser Punkte, d.h. die Aufnahme des Zylinderfußes im Unterchassis und der Endpunkt der Zugstrebenanordnung bewirkt, daß die Hubkraft durch äquivalente Zugkraft eine Umlenkung um die Schwenkachse erfährt. In dieser Anordnung der Elemente wird die Hubkraft des Zylinders neutralisiert, so daß das Unterchassis nicht belastet wird. Dieses sowie auch die Hubarme können aufgrund der erfindungsgemäßen Anordnung schwächer und damit gewichtssparend dimensioniert werden.To the starting point of the lifting force of the hydraulic cylinder in the To relieve sub-chassis, and to divert from horizontal To allow in vertical movement is one according to the invention Tension strut arrangement from the line of the pivot axis of the lifting arm provided for the output of the lifting force at the cylinder base. The overlay these points, i.e. the inclusion of the cylinder base in the lower chassis and the end point of the tension strut assembly causes the Lifting force through a deflection around the deflection Experienced swivel axis. In this arrangement of elements, the The cylinder's lifting force is neutralized so that the lower chassis is not charged. This as well as the lifting arms can be due to the arrangement according to the invention is weaker and thus saves weight be dimensioned.

In weiterer Ausgestaltung der Erfindung weist der zweite, also nicht vom Hydraulikzylinder beaufschlagte Hubarm, in analoger Weise zum ersten Hubarm eine Auskragung mit einem von seiner Schwenkachse gleich beabstandeten Anlenkpunkt auf. An diesen Anlenkpunkt greift ein Ende einer spannbaren Zugstange an, deren anderes Ende an den Anlenkpunkt der Auskragung des ersten Hubarms angreift.In a further embodiment of the invention, the second, ie Lift arm not acted on by the hydraulic cylinder, in analogue Way to the first lift arm with one of his Pivot axis equally spaced articulation point. At this point of articulation attacks one end of a tensionable tie rod, the the other end to the pivot point of the projection of the first lifting arm attacks.

Aufgrund der Spannbarkeit der Zugstange kann eine Vorspannung erzeugt werden, die bewirkt, daß das Parallelogrammchassis auch bei größeren Lasten gleichmäßig bewegt wird. Klemmungen des Parallelogramms sind auf diese Weise ausgeschlossen, so daß eine stärkere Dimensionierung der Bühnenbauteile aus diesem Grunde nicht erforderlich ist.Due to the tension of the drawbar, a preload can be used are generated, which causes the parallelogram chassis also is moved evenly with larger loads. Clamps of the parallelogram are excluded in this way, so that a stronger dimensioning of the stage components for this reason is not required.

Die erfindungsgemäße Lösung gestattet die Herstellung einer Hebebühne, die im wesentlichen lediglich die Kräfte der zu hebenden Last aufzunehmen hat, und damit entsprechend schwach dimensioniert werden kann. Damit ist ein Eigengewicht/Hubkraft-Verhältnis von bis zu etwa 1/6 möglich.The solution according to the invention allows the production of a Lift, which is essentially just the forces of the lift Has to take load, and therefore dimensioned accordingly weak can be. This is a dead weight / lifting power ratio up to about 1/6 possible.

Die erfindungsgemäße Hebebühne besteht, wie bekannte Hebebühnen auch, aus einem Unterchassis 3, einem Oberchassis 16 und zwei parallel geführten Hubarmen 4 und 10, die in den Punkten 7 und 17 bzw. 12 und 18 am Unterchassis 3 bzw. Oberchassis 16 schwenkbar angelenkt sind.The lifting platform according to the invention consists, like known lifting platforms also, from a lower chassis 3, an upper chassis 16 and two parallel lifting arms 4 and 10, which in points 7 and 17 or 12 and 18 on the lower chassis 3 or upper chassis 16 are pivotally articulated.

Die Konstruktion der Hubarme 4 und 10 geht aus den Fig. 6.1, 6.2 bzw. 7.1, 7.2 hervor. Beide Hubarme haben zwei Längsprofile 19, die durch zwei Querprofile 20 starr miteinander verbunden sind. An den beiden Enden der Längsträger sind jeweils Lageraugen 7, 17 bzw. 12, 18 zur Aufnahme der dazugehörigen Schwenkachsen vorgesehen. The construction of the lifting arms 4 and 10 is shown in FIGS. 6.1, 6.2 or 7.1, 7.2. Both lifting arms have two longitudinal profiles 19, rigidly connected to one another by two transverse profiles 20 are. There are bearing eyes on each of the two ends of the side members 7, 17 or 12, 18 for receiving the associated swivel axes intended.

Mit dem Querprofil 20 des Hubarmes 4 sind zwei parallel angeordnete Hubbleche 9 starr verbunden, die nach unten auskragen, was insbesondere aus Fig. 6.2 hervorgeht. Etwa am tiefsten Punkt dieser Auskragung ist ein Lagerbolzen 8 vorgesehen, der beide Hubbleche 9 durchsetzt. Oberhalb dieses Bolzens 8 sind an den Hubblechen 9 koaxial zu den Lageraugen 7 weitere Lagerbolzen 6 vorgesehen.With the cross section 20 of the lifting arm 4, two are arranged in parallel Lifting plates 9 rigidly connected, which project downwards, which is particularly evident from Fig. 6.2. About at the lowest point this projection a bearing pin 8 is provided, both Lift plates 9 penetrated. Above this bolt 8 are on the Lifting plates 9 coaxial with the bearing eyes 7 further bearing bolts 6 intended.

An das Querprofil 20 des Hubarmes 10 ist mittig ein Hubblech 9 angeschweißt, das ebenfalls nach unten auskragt, und etwa im tiefsten Punkt von einem Lagerbolzen 11 durchsetzt ist. Der Abstand 15 zwischen dem Lagerbolzen 11 und einer zwischen den Lageraugen 12 gedachten Linie ist gleich dem Abstand 15 zwischen dem Lagerbolzen 8 und einer zwischen den Lageraugen 7 gedachten Linie.At the cross section 20 of the lifting arm 10 is a lifting plate in the middle 9 welded, which also protrudes downwards, and in about lowest point is penetrated by a bearing pin 11. The distance 15 between the bearing pin 11 and one between the bearing eyes 12 imaginary line is equal to the distance 15 between the bearing pin 8 and an imaginary between the bearing eyes 7 Line.

Auf das Unterchassis 3 sind U-förmige Lagerböcke 21 aufgeschweißt, die zwischen ihren Wangen die Längsprofile 19 der Hubarme 4 und 10 aufnehmen. Die Anlenkung der Hubarme 4, 10 erfolgt durch Schwenkachsen, die durch die Lageraugen 7 bzw. 12 und in den Wangen der Lagerböcke 21 entsprechend vorgesehene Bohrungen eingesteckt werden.U-shaped bearing blocks 21 are welded onto the lower chassis 3, between their cheeks the longitudinal profiles 19 of the lifting arms Record 4 and 10. The lifting arms 4, 10 are articulated by pivot axes through the bearing eyes 7 and 12 and in bores corresponding to the cheeks of the bearing blocks 21 be plugged in.

Der Hydraulikzylinder 1 ist am Punkt 2 am Unterchassis 3 abgestützt. An eben diesem Punkt 2 greifen zwei parallel verlaufende Zugstreben 5 an, deren anderes Ende durch die Lagerbolzen 6 an den beiden Hubblechen 9 des Hubarmes 4 gehaltert sind. Das Pleuelauge des Hubzylinderkolbens sitzt zwischen den beiden Hubblechen 9 auf dem Lagerbolzen 8.The hydraulic cylinder 1 is at point 2 on the lower chassis 3 supported. At this point 2, two parallel grips engage Pull struts 5, the other end of which through the bearing bolts 6 are held on the two lifting plates 9 of the lifting arm 4. The The connecting rod eye of the lifting cylinder piston sits between the two lifting plates 9 on the bearing pin 8.

Auf dem Lagerbolzen 8 sind auch die Enden einer Zugstange 14 gelagert. Diese Zugstange 14 besteht, was aus den Figuren nicht hervorgeht, aus zwei parallel geführten Streben. Die Enden dieser beiden Streben liegen außen an den Hubblechen 9 an. The ends of a tie rod 14 are also on the bearing pin 8 stored. This tie rod 14 is what is not from the figures emerges from two parallel struts. The ends of this Both struts are on the outside of the lifting plates 9.

Die Zugstange 14 ist in zwei Längsabschnitte geteilt, wobei diese beiden Längsabschnitte durch eine verstellbare Bolzenmutteranordnung 22 miteinander verbunden sind. Der zum Hubarm 10 führende Längsabschnitt der Zugstange 14 ist über den Lagerbolzen 11 an das Hubblech 13 angelenkt. Dabei liegen die Enden der beiden Streben links und rechts am Hubblech 13 an, der Abstand der Streben der Zugstange 14 ist also in diesem Längsabschnitt geringer als der der Streben im anderen Längsabschnitt der Hubstange 14.The pull rod 14 is divided into two longitudinal sections, wherein these two longitudinal sections by an adjustable bolt nut arrangement 22 are interconnected. The lift arm 10 leading longitudinal section of the tie rod 14 is over the bearing pin 11 hinged to the lifting plate 13. The ends of the two lie Strive left and right on the lifting plate 13, the distance of the Striving for the tie rod 14 is therefore less in this longitudinal section than that of the struts in the other longitudinal section of the lifting rod 14.

Über die Rohr-Mutter-Anordnung 22 der Zugstange 14 kann durch entsprechend festes Anziehen der Mutter eine Vorspannung zwischen den beiden Hubstangen 4 und 10 hergestellt werden. Dadurch wird gewährleistet, daß sich die beiden Hubarme 4, 10 auch bei grösseren Lasten völlig parallel zueinander bewegen.About the tube-nut assembly 22 of the tie rod 14 can by accordingly tightening the nut a preload between the two lifting rods 4 and 10 are manufactured. This will ensures that the two lifting arms 4, 10 are also larger Move loads completely parallel to each other.

Der Hydraulikzylinder 1 hat etwa eine Hubkraft von 2,7 t. Diese wird bei der erfindungsgemäßen Hebebühne nicht in das Unterchassis 3 abgeführt, sondern über die Zugstreben 5 auf die Hubbleche 9 abgeleitet. Die Belastung der Bauteile der Hebebühne durch den Hydraulikzylinder wird damit praktisch neutralisiert. In der Folge kann eine erfindungsgemäße Hebebühne sehr leicht gebaut werden. In einem Test konnten 760 kg bei einem Eigengewicht der Hebebühne von 82 kg problemlos gehoben werden.The hydraulic cylinder 1 has a lifting capacity of approximately 2.7 t. This is not in the lower chassis in the lift according to the invention 3 dissipated, but via the tension struts 5 on the Lifting plates 9 derived. The load on the components of the lift it is practically neutralized by the hydraulic cylinder. As a result, a lifting platform according to the invention can be built very easily become. In one test, 760 kg could be weighed the lift of 82 kg can be lifted easily.
