Abstract

A towing-away device for vehicles of all kinds, in particular for motor vehicles, is to be developed. The invention consists in the fact that the device consists of a cylinder which is open at one end and into which a piston rod is inserted from the open side and is guided in a sealing fashion via a piston, a non-return valve with releasable lock opening into the closed cylinder space, whilst a compression spring which strikes against a closure part at the open end of the cylinder is arranged in the open cylinder space.

Description

Abschleppvorrichtung für Towing device for

Fahrzeuge aller Art Die Erfindung betrifft eine Abschleppvorrichtung für Fahrzeuge aller Art, insbesondere für Kraftfahrzeuge. Vehicles of all types The invention relates to a towing device for vehicles of all kinds, in particular for motor vehicles.

Es ist bekannt, starre Abschleppvorrichtungen für PKW's oder LKW's zu verwenden. In dieser Form ist sie auch als zusammenlegbare Stange für den PKW-Bereich im Handel.It is known, rigid towing devices for cars or trucks to use. In this form it is also available as a collapsible pole for the car area in trade.

Bei starren Abschleppvorrichtungen besteht ein Nachteil darin, daß zum Anbringen der Stange die beteiligten Fahrzeuge genau positioniert werden müssen, was z.T. auch für die zusammenlegbaren Abschleppstangen zutrifft.A disadvantage with rigid towing devices is that the vehicles involved must be precisely positioned to attach the bar, which partly also applies to the collapsible tow bars.

Ein weiterer Nachteil besteht darin, daß die horizontale und vertikale Lage der Abschleppösen an den beteiligten Fahrzeugen durch Verdrehen von Kolbenstange und Zylinder jeweils angepaßt werden muß.Another disadvantage is that the horizontal and vertical Position of the towing eyes on the vehicles involved by turning the piston rod and cylinder must be adapted.

Aufgabe der vorliegenden Erfindung ist es, den erwähnten Nachteil zu vermeiden und eine beim Anfahren und Bremsen ruckfreie Abschleppvorrichtung zu entwickeln, die ebenso wie die zusammenlegbare Abschleppstange platzsparend im Auto zu verstauen ist.The object of the present invention is to remedy the disadvantage mentioned and a towing device that is jerk-free when starting and braking develop which, like the collapsible tow bar, save space in the car is to be stowed away.

Die Aufgabe wird durch die in den Ansprüchen angegebenen Merkmale gelöst. Durch die teleskopartige Ausbildung der Abschleppvorrichtung ist es möglich, den Abschleppvorgang zu vereinfachen. Beim Anbringen der Abschleppvorrichtung fällt das bisher notwendige Positionieren der am Abschleppvorgang beteiligten Fahrzeuge weg, da die erfindungsgemäße Abschleppvorrichtung in weiten Grenzen einstellbar ist. Die Einstellbarkeit reicht von der Grundlänge im zusammengeschobenen Zustand bis zur Anlage der Druck feder an die Federdruckplatte bzw. des Verschlußteils. Der Hubweg der Abschleppvorrichtung beträgt auf diese Weise mindestens 500 mm.The object is achieved by the features specified in the claims solved. Due to the telescopic design of the Towing device it is possible to simplify the towing process. When attaching the towing device The previously necessary positioning of the vehicles involved in the towing process is no longer necessary away, since the towing device according to the invention can be adjusted within wide limits is. The adjustability ranges from the basic length when pushed together until the pressure spring rests on the spring pressure plate or the closure part. The lifting path of the towing device is at least 500 mm in this way.

Der Abschleppvorgang wird auch insofern vereinfacht, als beim Anfahren oder Abbremsen keine ruckartigen Beschleunigungen bzw. Verzögerungen innerhalb des Hubweges auftreten können. Dies wird durch das Zusammenwirken von Druckfeder, Kolbenwirkung und Rückschlagventil ermöglicht.The towing process is also simplified to the extent that it is when moving off or braking no jerky accelerations or decelerations within the Stroke can occur. This is achieved through the interaction of the compression spring and piston action and check valve allows.

Im folgenden wird die Erfindung anhand mehrerer Ausführungsbeispiele näher erläutert. Es zeigen: Fig. 1 = Längsschnitt durch eine erfindungsgemäße Abschleppvorricatung Fig. 2 = Längsschnitt durch die erfindungsgemäße Abschleppvorrichtung im Kolbenbereich In Fig. 1 ist der Zylinder 1 mit Anschlußenden 9,10 und Verriegelung 12a,12b dargestellt, die zum spielfreien Anbringen der Abschleppvorrichtung an der Abschleppöse 11a,11b dienen. In dem Zylinder 1 befindet sich die Kolbenstange 2, an deren einem Ende der Kolben 3 über eine Innensechskantschraube 13 befestigt ist. Am anderen Ende der Kolbenstange 2 befindet sich das Anschlußende 10, das in gleicher Weise wie das Anschlußende 9 zur spielfreien Befestigung der Abschleppvorrichtung an das beteiligte Fahrzeug dient.In the following the invention is based on several exemplary embodiments explained in more detail. They show: FIG. 1 = longitudinal section through a towing device according to the invention Fig. 2 = longitudinal section through the towing device according to the invention in the piston area In Fig. 1, the cylinder 1 is shown with connecting ends 9,10 and locking 12a, 12b, for the play-free attachment of the towing device to the towing eye 11a, 11b to serve. In the cylinder 1 is the piston rod 2, at one end the piston 3 is fastened by means of a hexagon socket screw 13. On the other end the piston rod 2 is the connection end 10, which is in the same way as the connection end 9 for backlash-free attachment of the towing device to the involved Vehicle is used.

Zwischen Kolben 3 und Verschlußteil 8 befindet sich eine Druckfeder 7, die so ausgelegt ist, daß ruckfreies Anschleppen gewährleistet ist. Der Zylinderraum 4 steht über das Rückschlagventil 5 mit der äußeren Atmosphäre in Verbindung. Zur Vermeidung von reibendem Verschleiß befindet sich auf der Lauffflächedes Verschlußteils 8 eine Kunststofflaufbuchse 14.Between the piston 3 and the closure part 8 there is one Compression spring 7, which is designed in such a way that jolt-free towing is guaranteed. The cylinder space 4 is in communication with the outside atmosphere via the check valve 5. To the Avoidance of frictional wear is on the running surface of the closure part 8 a plastic bushing 14.

In Fig. 2 ist eine genauere Ansicht des Kolben dargestellt.In Fig. 2 a more detailed view of the piston is shown.

Dieser befindet sich im Zylinder 1 und wird über einen Führungsbund 15 axial geführt. Die Federdruckplatte 16 ist zusammen mit dem Kolben über die Innensechskantschraube 13 in der Zylinderstange 2 befestigt. Die Dichtlippen 17 werden durch Schraubendruckfedern 18,19 auseinandergepreßt. Der Einspannflansch 20 sorgt hierbei für eine Versteifung des Kolben, so daß ein dichter Komplettkolben entsteht.This is located in cylinder 1 and is via a guide collar 15 axially guided. The spring pressure plate 16 is together with the piston via the hexagon socket screw 13 fastened in the cylinder rod 2. The sealing lips 17 are made by helical compression springs 18:19 pressed apart. The clamping flange 20 ensures stiffening of the piston, so that a tight complete piston is created.

Das Rückschlagventil, bestehend aus VentiAncpf zur Aufhebung der Sperre, Ventilstössel, Ringspalt und Ventildichtung ist von üblicher Bauart.The non-return valve, consisting of a valve control to cancel the lock, The valve stem, annular gap and valve seal are of the usual design.

Beim Anfahren wird Luft über das Rückschlagventil 5 in den Zylinderraum 4 angesaugt. Das Einströmen der Luft beim Anschleppen wird durch einen engen Ringspalt verlangsamt.When starting up, air is drawn into the cylinder space via the check valve 5 4 sucked in. The influx of air when towing is through a narrow annular gap slowed down.

Dadurch entsteht eine dämpfende Wirkung beim Abschleppvorgang.This creates a dampening effect during the towing process.

Beim Abbremsen wird der Komplettkolben gege-n das Luftpolster im Zylinderraum 4 gedrückt, wodurch eine abgedämpfte Verzögerung entsteht.When braking, the complete piston is against the air cushion in the cylinder chamber 4 is pressed, creating a dampened delay.

Nach Beendigung des Abschleppvorganges kann durch Betätigung eines Venti-lknopfes die Luft aus dem Zylinderraum 4 entweichen, so daß die Kolbenstange 2 vollständig in den Zylinder 1 eingeschoben werden kann und dadurch das kleinstmögliche Stauvolumen der Abschleppvorrichtung erreicht wird.After the towing process has ended, you can press a Valve button the air escape from the cylinder chamber 4, so that the piston rod 2 can be pushed completely into the cylinder 1 and thus the smallest possible Storage volume of the towing device is reached.
