  In der Zeichnung ist ein     Ausführungsbeispiel    des  Erfindungsgegenstandes mit den im vorliegenden Zu  sammenhang     wesentlichen    Teilen dargestellt.  



  Es zeigen:       Fig.    1 einen Aufriss eines     Zweiradanhängers    in zwei  verschiedenen Höhenlagen der Ladebrücke in bezug auf  die Räder und       Fig.    2 einen Teil des Grundrisses zu     Fig.    1.  



  Der dargestellte     Zweiradanhänger    hat     ein    Fahrge  stell 1, welches die nur teilweise dargestellte Ladebrücke  2 trägt. An dem Fahrgestell 1 sind die beiden Räder 3  mittels je eines     Längslenkers    4     aufgehängt.    Die     Längs-          lenker    sind fest mit einer am Fahrgestell 1 ,drehbar gela  gerten Welle 5 verbunden. Die Deichsel 6 ist durch  einen     Arm    eines     Winkelhebels        gebildet,    der in einer  vertikalen Ebene schwenkbar ist.

   An einem der Quer  träger des     Fahrgestelles    1 sind ,die Zylinder zweier       hydraulischer        Zylinder-Kolben-Einheiten    7     befestigt.    Die       Kolbenstange    dieser Einheiten greifen an eine Tra  verse 8 an, die in Längsschlitzen 9 der Längsträger des       Fahrgestelles    1 geführt und in der Längsrichtung des  Anhängers verschiebbar ist. In :der ausgezogen darge  stellten Lage der Traverse 8 stehen .die     Zylinder-Kol-          ben-Einheiten    7 unter Druck. Die Traverse 8 ist ,durch  eine Zugstange 10 mit dem anderen Arm 11 des Win  kelhebels verbunden.

   Zwei Zugbänder 12 sind je mit  einem Ende an der Traverse 8 und mit dem anderen  Ende an einer Kette 13 befestigt, welche mit einem     Ket-          tenradsegment    14 im Eingriff steht, das fest mit der  Welle 5 verbunden ist. Der     Arbeitsraum    der     Zylinder-          Kolben-Einheiten    7 ist durch eine (nur teilweise darge  stellte) Leitung 15 mit einer     Anschlussarmatur    16 ver  bunden. Diese Anschlussarmatur 16 dient dazu, die Lei  tung 15 an die     Hydraulikanlage    des Zugfahrzeuges (z. B.

      eines Traktors)     anzuschliessen.    Der Anhänger hat nicht       dargestellte        Arretiermittel,    welche es ermöglichen, die  Deichsel 6 und den Längslenker 4 in     wenigstens    einer  wählbaren     Stellung    zu arretieren, wozu eine Arretierung  eines     .dieser    Teile oder der Traverse 8 genügt. Diesem  Zweck kann auch ein     Schliessventil    in .der Leitung 15  oder     in    der     Hydraulikanlage    des     Zugfahrzeuges    die  nen.

   Es ist jedoch     eine        zusätzliche,        mechanische    Arre  tierung     zweckmässig.     



  Wenn in der ausgezogen     dargestellten    Lage der be  weglichen Teile der Arbeitsraum der     Zylinder-Kolben-          Einheiten    7, gegebenenfalls nach Lösen der Arretie  rung, vom Druck entlastet wird, schwenken die Deichsel  6 und die Längslenker 4     unter    der Wirkung des Gewich  tes insbesondere des Fahrgestells 1 und     gegebenenfalls     der Last in die     strichpunktiert        dargestellte        Stellung    6'  bzw.

   4',     wobei.        die        Traverse    8 in die     Stellung    8'     verscho-          ben    wird und .das Fahrgestell 1 mit der Ladebrücke 2  sich in     die        Stellung    1'     bzw.    2'     senkt.     



  Für ein     Zugfahrzeug    mit gegebener Höhe des       Zughakens    über ;dem     Boden,        sind    die Länge der  Deichsel 6 und des Armes 11 in bezug auf diejenige     des     Längslenkers 4 so bemessen, und deren Neigungen so       gewählt,        dass    bei diesem Senkendes     Fahrgestelles    die auf  dasselbe bezogenen vertikalen Bewegungskomponenten  des Endes der Deichsel 6 und der Radachse an den  Enden der Längslenker 4     einander    wenigstens     annä@          hernd    gleich sind,

   .sodass das     Fahrgestell    und die Lade  brücke ihre     horizontale        (bzw.    zum Boden parallele)     Lage     beibehalten.  



  Um den     Zweiradanhänger    auch bei     Zugfahrzeugen          mit        anderer    Höhe des Zughakens über dem Boden ver  wenden zu können,     können    die Länge und die Neigung  der Deichsel 6     und/o@der    des Armes 11     und/oder    der  Zugstange 10     veränderbar        sein.     



  Indem ,die     Zylinder-Kolben-Einheiten    7     beaufschlagt     werden, kann das Fahrgestell mit der Ladebrücke und       gegebenenfalls    der     Last    wieder ohne von der Horizon  talen nennenswert abzuweichen in die ausgezogen     dar-          gestellte        Lage    1 bzw. 2     gehoben        werden.    Auf     dieselbe         Weise kann das Fahrgestell mit der Ladebrücke und     ge-          gebenenfalls    der Last     auch    ;

  auf     eine        innerhalbder        ge;geb.e-          nen        Grenzen    beliebige Höhe gesenkt oder gehoben und  in dieser Höhe durch Schliessen des Ventils in der     Lei-          turig    arretiert werden. Wenn der Anhänger die zusätzli  che mechanische     Arretiervorrichtung    hat, kann das  Fahrgestell auch durch diese je nach .deren Ausführung       in    einer beliebigen oder einer     wählbaren    von mehreren  Höhenlagen arretiert werden.  



  An die Stelle der     Zylinder-Kolben-Einheiten    7 kann  auch eine     Antriebsvorrichtung    anderer     Art    treten. Bei  spielsweise kann die Traverse 8 mittels zweier durch  eine Handkurbel     gemeinsam        antreibbarer    Gewindespin  deln verschiebbar sein. An     Stelle    des     Zwgmittelgetriebes     12, 13, 14 ist beispielsweise auch ein Hebelgetriebe ver  wendbar.



      Two-wheel trailer The invention relates to a two-wheel trailer and aims to create a simple and reliable trailer in which the Fahrge alternately adjustable in height relative to the wheels and the drawbar on the chassis can be pivoted to facilitate loading and unloading by means of a drive device.



  In the drawing, an embodiment of the subject invention is shown with the essential parts in the present context.



  There are shown: FIG. 1 an elevation of a two-wheel trailer in two different heights of the loading bridge in relation to the wheels; and FIG. 2 a part of the outline for FIG. 1.



  The two-wheel trailer shown has a Fahrge alternate 1, which carries the dock leveler 2, which is only partially shown. The two wheels 3 are suspended from the chassis 1 by means of a trailing arm 4 each. The trailing arms are firmly connected to a shaft 5 which is rotatably supported on the chassis 1. The drawbar 6 is formed by an arm of an angle lever which is pivotable in a vertical plane.

   On one of the cross members of the chassis 1, the cylinders of two hydraulic cylinder-piston units 7 are attached. The piston rod of these units attack a Tra verse 8, which is guided in longitudinal slots 9 of the side members of the chassis 1 and is displaceable in the longitudinal direction of the trailer. In: the position of the cross member 8 shown in solid lines, the cylinder-piston units 7 are under pressure. The traverse 8 is connected by a pull rod 10 to the other arm 11 of the winch lever.

   Two tension straps 12 are each fastened at one end to the cross member 8 and at the other end to a chain 13 which engages with a chain wheel segment 14 which is firmly connected to the shaft 5. The working chamber of the cylinder-piston units 7 is ver by a (only partially Darge presented) line 15 with a connection fitting 16 connected. This connection fitting 16 is used to connect the line 15 to the hydraulic system of the towing vehicle (e.g.

      a tractor). The trailer has locking means, not shown, which make it possible to lock the drawbar 6 and the trailing arm 4 in at least one selectable position, for which purpose a locking of one of these parts or the traverse 8 is sufficient. A closing valve in the line 15 or in the hydraulic system of the towing vehicle can also serve this purpose.

   However, it is advisable to use an additional mechanical locking mechanism.



  If, in the position of the moving parts shown in solid lines, the working space of the cylinder-piston units 7 is relieved of pressure, possibly after loosening the locking mechanism, the drawbar 6 and the trailing arm 4 pivot under the effect of the weight, especially of the chassis 1 and, if necessary, the load in the position 6 'or

   4 ', where. the traverse 8 is moved into the position 8 'and. the chassis 1 with the loading bridge 2 is lowered into the position 1' or 2 '.



  For a towing vehicle with a given height of the draw hook above; the ground, the length of the drawbar 6 and the arm 11 are dimensioned in relation to that of the trailing arm 4, and their inclinations are chosen so that when the chassis is lowered, the vertical movement components related to it the end of the drawbar 6 and the wheel axle at the ends of the trailing arm 4 are at least approximately the same,

   .so that the chassis and the loading bridge maintain their horizontal (or parallel to the ground) position.



  In order to be able to use the two-wheel trailer also in towing vehicles with a different height of the draw hook above the ground, the length and inclination of the drawbar 6 and / or that of the arm 11 and / or the pull rod 10 can be changed.



  By acting on the cylinder-piston units 7, the chassis with the loading bridge and possibly the load can again be lifted into the position 1 or 2 shown in solid lines without deviating significantly from the horizontal. In the same way, the chassis with the loading bridge and, if necessary, the load;

  be lowered or raised to any height within the given limits and locked in the pipe at this height by closing the valve. If the trailer has the additional mechanical locking device, the chassis can also be locked by this, depending on the design, in any or one of several heights that can be selected.



  Instead of the cylinder-piston units 7, a drive device of another type can also be used. For example, the traverse 8 can be slidable by means of two threaded spindles that can be driven together by a hand crank. In place of the mid-drive mechanism 12, 13, 14, for example, a lever mechanism can also be used.
