Description

8'IOßEAEIE TELESKOPABSCHLEPPSTANGE EUR STRAßEHFAHRZEUGEN8'IOßEAEIE TELESKOPLESCHLEPPANGE EUR ROAD VEHICLES

Die Erfindung bezieht sich auf eine Abschleppstange(weiter mit der nbkürzung S T A S genannt),die zur Verbindung von Straßen-fahrzeugen dient,dabei sind zwei Yierkantrohre von verschiedenen Kaßen ineinander geschoben.The invention relates to a towing bar (also called abbreviation S T A S), which is used to connect road vehicles, two Yierkantrohre of different tills are pushed into each other.

Die Abschleppstange ermöglicht im Straßenverkehr Abschleppen der beschädigten Straßenfahrzeuge.Am Ende der Abschleppstange sind zwei Zugösen verschweißt.Eine von den Osen ist am angezogenen Straßenfahrzeug verbunden,.die andere am Schlepp-fahrzeng.'.venn beide Straßenfahrzeugen sich in Bewegung setzen, entstehen schadliche Stöße die,die Kupplung und das Schalt-getriebe des Schleppfahrzeugs dynamisch belasten. .außerdem nach St.Y.O.muß die lange der Abschleppstange so ausgewählt werden,daß die beiden Straßenfahrzeuge manövrier-fahig sind.In jedem Fall ist die Stange über zwei Meter lang.The tow bar enables the damaged road vehicles to be towed in road traffic. At the end of the tow bar, two towing eyes are welded, one of the eyes is connected to the pulled-on road vehicle, the other to the tow vehicle. When both road vehicles start moving, harmful shocks occur dynamically load the clutch and the gearbox of the towing vehicle. In addition, according to St.Y.O., the length of the tow bar must be selected so that the two road vehicles are maneuverable. In any case, the bar is over two meters long.

Bei einer solchen Lange ist es unmöglich die Abschleppstange im Eahrerhaus mitzunehmen.With such a length, it is impossible to take the tow bar with you in the cab.

Hier will die Erfindung Abhilfe schaffen.Die Erfindung v/ie sie in den xi-nsprüchen gekennzeichnet ist,lost die Aufgabe einer Abschleppstange die stoßfrei ist,und ins Eahrerhaus problemlos mitgenommen werden kann,dabei mit Hilfe der Gummi-puffer die schädlichen dynamischen Belastungen,zwischen beiden Straßenfahrzeugen vermeidet.This is where the invention seeks to remedy the problem. The invention, as it is characterized in the claims, solves the task of a tow bar that is bumpless and can be easily taken into the driver's cab, using the rubber buffers to remove the damaging dynamic loads, between two road vehicles.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen,daß die relative Bewegung zwischen den teleskop-weise montierten Aohren stoßfreie Belaßtung der Kupplung und des Schaltgetriebe,des Schleppers versichert.The advantages achieved by the invention are essentially to be seen in the fact that the relative movement between the telescopically mounted ears assures bumpless leaving of the coupling and the gearbox, the tractor.

Insgesamt zeichnet sich die STAS durch eine hohe lebensdauer aus.Overall, the STAS is characterized by a long service life.

Im folgenden wird die Erfindung anhand von lediglich einem iiusführungsweg darstellenden Zeichnungen näher erläutert.In the following, the invention is explained in more detail with the aid of drawings illustrating only one guidance route.

Es zeig Eig.l in Vordernansicht einer erfindungsmäßig.er STAS im Arbeitzustand,und Fig. 2 seigt STAS zusammengesetzt.It shows Eig.l in front view of a STAS according to the invention in the working state, and Fig. 2 shows STAS assembled.

Fig. 3 zeigt das kiene Vierkantrohr zusammen mit der verschweßten Zugöse,zwei Gummipuffern und Absteckbolzen,als Kraftüber-tragungselement.Fig.4 ist Draufsicht vom Fig.3.Fig. 3 shows the square tube together with the welded towing eye, two rubber buffers and locking pins, as a force transmission element. Fig. 4 is a top view of Fig. 3.

Die Arretierung des Absteckbolzens erfolgt mit einem Haken, der für den Absteckbolzen durch eine Kette yerbunden ist.The locking pin is locked with a hook that is connected by a chain for the locking pin.

In den Figuren ist eine STAS und entsprechende Detaile dargestellt,welche in seinem grundsätzlichen Aufbau aus einem Vierkantrohr 3 in den zwei kleinere Rohre 4 koaxial durchgezogen sind,im Rohr 3-inneren.In the figures, a STAS and corresponding details are shown, which in their basic structure consist of a square tube 3 in which two smaller tubes 4 are coaxially drawn, in the tube 3-interior.

Me Rôhre 4 haben zwei verschiedene Positioner gegen Rohr 3 wie es an die Pig.l und Fig.2 gezeigt ist,d.h die Rôhre 4 bewegt sich innern im Rohr 3,so daß die gesamtelänge stüfenweise verändert wird.Me tube 4 have two different positions against tube 3 as shown on the Pig.l and Fig.2, i.e. the tube 4 moves inside the tube 3, so that the total length is gradually changed.

Fig.3 zeigt Rohr 4 zusammen mit den zwei Gummipuffern 6(die Stöße eliminieren) Zugöse 5 und Absteckbolzen 2,der als Kraft-übertragungselement zwischen die Rôhre 3 und 4 dient.3 shows tube 4 together with the two rubber buffers 6 (which eliminate shocks) drawbar eye 5 and locking pin 2, which serves as a force transmission element between tubes 3 and 4.

Hier ist die Arretierng des Absteckbolzens durch den Hacken 7 gesichert,der ist mit der Hilfe der Kette 8 für die Absteckbolzen verbunden.Here the locking of the locking pin is secured by the hook 7, which is connected with the help of the chain 8 for the locking pin.

Damit die STAS sich bequem der Hand anpasst,hilft der Griff 1.Handle 1 helps the STAS to adapt comfortably to the hand.
