Claims (7)

1. Hebebühne, insbesondere für Kraftfahrzeuge, mit zwei beidseits an­ greifenden Hubsystemen, die simultan das Hochfahren und Absenken der Hebebühne bewirken, wobei jedes Hubsystem aus zwei nebeneinander an­ geordneten Zylinder-Kolben-Aggregaten (16a, 17b; 17a, 16b) besteht, die folgendermaßen hydraulisch zusammenwirken: In jedem Hubsystem ist das eine Zylinder-Kolben-Aggregat (16a und 17a) an eine Hydraulikpumpe an­ geschlossen und fungiert als Kommandoaggregat, wogegen das andere Zylinderkolbenaggregat (17b, 16b) an das Kommandoaggregat des jeweils anderen Hubsystems angeschlossen ist und also Folge-Aggregat fungiert, indem der Hydraulikmittelabfluß aus dem Kommando-Aggregat zur Betäti­ gung des Folge-Aggregats des jeweils anderen Hubsystems dient, dadurch gekennzeichnet, daß bei jedem der beiden Hubsysteme zumindest ein Zylinder-Kolben- Aggregat über ein Koppelglied (18a, 18b; 28a, 28b) an die Hebebühne an­ geschlossen ist und dieses Koppelglied zum Ausgleich von Relativbewe­ gungen zwischen den Zylinderkolbenaggregaten (16a, 17b; 17a, 16b) des gleichen Hubsystems dient.1. Lift, in particular for motor vehicles, with two lifting systems that engage on both sides, which simultaneously raise and lower the lifting platform, each lifting system consisting of two cylinder-piston units arranged side by side ( 16 a, 17 b; 17 a, 16 b ), which interact hydraulically as follows: In each lifting system, one cylinder-piston unit ( 16 a and 17 a) is connected to a hydraulic pump and acts as a command unit, whereas the other cylinder-piston unit ( 17 b, 16 b) is connected to the command unit of the other lifting system is connected and thus the following unit functions by the hydraulic fluid drain from the command unit for actuating the subsequent unit of the other lifting system, characterized in that in each of the two lifting systems at least one cylinder-piston unit via a coupling link ( 18 a, 18 b; 28 a, 28 b) to the lift is closed and this coupling link to compensate for vo n relative movements between the cylinder piston units ( 16 a, 17 b; 17 a, 16 b) serves the same lifting system. 2. Hebebühne nach Anspruch 1, dadurch gekennzeichnet, daß jedes Zylinder-Kolben-Aggregat (16a, 17b; 17a, 16b) über ein eigenes Koppelglied (18a, 18b; 28a, 28b) an die Hebebühne angeschlossen ist. 2. Lifting platform according to claim 1, characterized in that each cylinder-piston unit ( 16 a, 17 b; 17 a, 16 b) via its own coupling member ( 18 a, 18 b; 28 a, 28 b) to the lifting platform connected. 3. Hebebühne nach Anspruch 1, dadurch gekennzeichnet, daß die Zylinder-Kolben-Aggregate (16a, 17b; 17a, 16b) jeweils über ihre Kolbenstange an das Koppelglied (18a, 18b; 28a, 28b) angeschlossen sind.3. Lifting platform according to claim 1, characterized in that the cylinder-piston units ( 16 a, 17 b; 17 a, 16 b) each via their piston rod to the coupling member ( 18 a, 18 b; 28 a, 28 b) are connected. 4. Hebebühne nach Anspruch 1, dadurch gekennzeichnet, daß das Koppelglied (18a, 18b; 28a, 28b) als Schwenkhebel ausgebildet ist.4. Lifting platform according to claim 1, characterized in that the coupling member ( 18 a, 18 b; 28 a, 28 b) is designed as a pivot lever. 5. Hebebühne nach Anspruch 1, mit zweit seitlich nebeneinander angeord­ neten Scherengestellen (1, 2), jeweils bestehend aus zumindest zwei sich kreuzenden Scherenhebeln (11a, 11b, 12a, 12b; 21a, 21b, 22a, 22b) die an ihrem Kreuzungspunkt durch ein Scherengelenk schwenkbar verbunden sind und durch die genannten Hubsysteme zwischen einer unteren Ruhe­ stellung und einer oberen Arbeitsstellung verfahrbar sind, indem die Zylin­ der-Kolben-Aggregate (16a, 17b; 17a, 16b) auf Spreizhebel (18a, 18b; 28a, 28b) einwirken, die schwenkbar an einem Scherenhebel gelagert sind und sich bis zum Erreichen einer Zwischenhöhe der Bühne an einer festen Unterlage oder am korrespondierenden Scherenhebel abstützen, wogegen sie bei Erreichen der Zwischenhöhe gegen einen Anschlag (31a, 31b; 32a, 32b) des ihn tragenden Scherenhebels laufen, dadurch gekennzeichnet, daß die beiden nebeneinander angeordneten Zylinder-Kolben-Aggregate 16a, 17b; 17a, 16b) eines Hubsystems auf zwei getrennte Spreizhebel (18a, 18b; 28a, 28b) einwirken, die relativ zueinander verdrehbar sind und als Koppelglied fungieren.5. Lift according to claim 1, with two laterally side by side arranged scissor frames ( 1 , 2 ), each consisting of at least two intersecting scissor levers ( 11 a, 11 b, 12 a, 12 b; 21 a, 21 b, 22 a, 22 b) which are pivotally connected at their crossing point by a scissor joint and can be moved between a lower rest position and an upper working position by the lifting systems mentioned, by the cylinder-piston assemblies ( 16 a, 17 b; 17 a, 16 b ) act on spreading levers ( 18 a, 18 b; 28 a, 28 b), which are pivotally mounted on a scissor lever and are supported on a solid base or on the corresponding scissor lever until an intermediate height of the platform is reached, whereas they reach when the intermediate height is reached run against a stop ( 31 a, 31 b; 32 a, 32 b) of the scissor lever carrying it, characterized in that the two cylinder-piston units 16 a, 17 b; 17 a, 16 b) of a lifting system act on two separate spreading levers ( 18 a, 18 b; 28 a, 28 b) which can be rotated relative to one another and act as a coupling member. 6. Hebebühne nach Anspruch 1, dadurch gekennzeichnet, daß die Bewegung der Zylinder-Kolben-Aggregate (16a, 17b; 17a, 16b) desselben Hubsystems relativ zueinander durch Anschläge begrenzt ist. 6. Lifting platform according to claim 1, characterized in that the movement of the cylinder-piston units ( 16 a, 17 b; 17 a, 16 b) of the same lifting system relative to one another is limited by stops. 7. Hebebühne nach Anspruch 1, dadurch gekennzeichnet, daß die Relativbewegung der Zylinder-Kolben-Aggregate (16a, 17b; 17a; 16b) durch elastische, insbesondere vorgespannte Anschläge begrenzt ist.7. Lift according to claim 1, characterized in that the relative movement of the cylinder-piston units ( 16 a, 17 b; 17 a; 16 b) is limited by elastic, in particular prestressed stops.
