Description

Die vorliegende Erfindung betrifft eine Gelenkwelle, enthaltend zwei rohrartige Wellenteile, nämlich ein Aussenrohr und ein Innenrohr, wobei der Aussendurchmesser des Innenrohres kleiner ist als der Innendurchmesser des Aussenrohres, sodass das Innenrohr in das Aussenrohr einschiebbar ist. Diese Verschiebbarkeit ermöglicht eine Anpassung der Länge der Gelenkwelle an verschiedene Längenanforderungen. In der gewünschten Längenanpassung lassen sich die beiden Rohre durch eine an dem Aussenrohr angeordnete Klemmnabe fixieren, sodass eine Übertragung von Drehmomenten über die eingestellte Länge ermöglicht wird.The The present invention relates to a propeller shaft comprising two tubular shaft parts, namely an outer tube and an inner tube, wherein the outer diameter of the Inner tube is smaller than the inner diameter of the outer tube, so that the inner tube can be inserted into the outer tube. This displacement allows an adjustment of the length the PTO shaft to different length requirements. In the desired length adjustment the two tubes can be arranged by a arranged on the outer tube Fix the clamping hub, so that a transmission of torques about the set length allows becomes.

Die US 56 51 738 A beschreibt eine längenvariable Gelenkwelle, deren Querschnitt nicht kreisringförmig ist. Der Querschnitt weist sechs Ausbuchtungen auf, die die Hohlwelle versteifen.The US 56 51 738 A describes a variable length propeller shaft whose cross section is not circular. The cross section has six protrusions that stiffen the hollow shaft.

In der GB 778 508 ist das äußere Wellenteil rohrartig, das innere Wellenteil aber massiv. Auch in der US 60 83 108 ist das innere Wellenteil massiv. Das gleiche gilt für das innere Wellenteil der DE 27 47 319 A .In the GB 778,508 is the outer shaft part like a tube, the inner shaft part but massive. Also in the US 60 83 108 the inner shaft part is massive. The same applies to the inner shaft part of the DE 27 47 319 A ,

Die DE 83 12 41 U1 beschreibt eine Klemmnabe ohne nähere Erläuterung der Welle, auf der sie angeordnet werden soll.The DE 83 12 41 U1 describes a clamping hub without further explanation of the shaft on which it is to be placed.

Die DE 37 37 102 A1 offenbart eine mit Schrauben befestigbare Nabe, die auf einer massiven Welle angeordnet werden soll.The DE 37 37 102 A1 discloses a screw mountable hub to be mounted on a solid shaft.

Obwohl im gesamten Stand der Technik keine längenvariable Gelenkwelle mit zwei Hohlrohren beschrieben ist, die durch eine Klemmnabe fixiert werden können, wird überraschenderweise trotz der Klemmung der beiden Rohre durch die Klemmnabe der fehlerfreie Rundlauf der Gelenkwelle auch bei hohen Drehzahlen und hohen Drehmomenten nicht beeinträchtigt, sodaß diese Art der Kraftübertragung eine einfache Möglichkeit darstellt, die Gelenkwelle an verschiedenen Längenanforderungen anzupassen. Die Kraftübertragung lässt sich durch die Klemmung der Klemmnabe völlig spiel- und schlagfrei bewirken.Even though in the entire state of the art no variable length propeller shaft with two hollow tubes is described, which are fixed by a clamping hub can, is surprisingly despite the clamping of the two tubes by the clamping hub of the error-free Concentricity of the PTO shaft even at high speeds and high torques not impaired, so this Type of power transmission one easy way represents to adapt the PTO shaft to different length requirements. The power transmission let yourself completely free of play and impact due to the clamping of the clamping hub cause.

Die Klemmnabe kann beispielsweise mit einem Klemmkonus versehen sein oder einen separaten Klemmring aufweisen. Sie kann als separates Bauteil auf das Aussenrohr aufgebracht werden. Sie kann aber auch einstückig mit dem Aussenrohr gefertigt werden.The Clamping hub can be provided for example with a clamping cone or have a separate clamping ring. It can be used as a separate component be applied to the outer tube. But you can also work in one piece with be made the outer tube.

An beiden Enden der Gelenkwelle sind Kupplungen vorgesehen zur Verbindung mit den Antriebs- und Abtriebsseiten. Diese Kupplungen können übliche Kupplungen sein, beispielsweise Elastomerkupplungen, Metallbalgkupplungen oder Federscheibenkupplungen.At Both ends of the propeller shaft couplings are provided for connection with the drive and driven sides. These couplings can be conventional couplings be, for example, elastomer couplings, metal bellows couplings or Spring washer clutches.

Die Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnungen beispielhaft näher erläutert.The The invention will be described below with reference to the drawings example closer explained.

3 zeigt eine Ausführungsform mit einem Klemmring; 3 shows an embodiment with a clamping ring;

3a zeigt einen Schnitt durch die Ansicht der 3 entlang der Schnittlinie A-A. 3a shows a section through the view of 3 along the section line AA.

Das Aussenrohr 10 trägt an seinem Ende eine Kupplung 13, die als Elastomerkupplung ausgestaltet ist. Am anderen Ende des Aussenrohres 10 ist die, Klemmnabe 15 angeordnet, die als geschlitzte Klemmnabe mit Klemmschrauben 16 ausgestaltet ist, wie in 1a dargestellt ist. Das Innenrohr 11 hat einen kleineren Durchmesser als das Aussenrohr 10, sodass es in das Aussenrohr einschiebbar ist: An seinem freien, dem Aussenrohr abgewandten Ende ist eine zweite Kupplung 13 angeordnet. Durch Lösen der als Befestigungsmittel dienenden Klemmschrauben 16 der Klemmnabe 15 wird das Innenrohr 11 innerhalb des Aussenrohres 10 verschiebbar und lässt sich auf die gewünschte Länge einstellen. Durch Anziehen der Klemmschrauben 16 wird die Klemmnabe 15, die einen Schlitz 14 enthält, zusammengepresst und verklemmt dadurch das Innenrohr 11.The outer tube 10 carries at its end a clutch 13 , which is designed as elastomeric coupling. At the other end of the outer tube 10 is the, clamping hub 15 arranged as a slotted clamping hub with clamping screws 16 is designed as in 1a is shown. The inner tube 11 has a smaller diameter than the outer tube 10 , so that it can be inserted into the outer tube: At its free, the outer tube end facing away from a second clutch 13 arranged. By loosening the clamping screws used as fastening means 16 the clamping hub 15 becomes the inner tube 11 inside the outer tube 10 movable and can be adjusted to the desired length. By tightening the clamping screws 16 becomes the clamping hub 15 that have a slot 14 contains, compressed and thereby jammed the inner tube 11 ,

2 zeigt eine Klemmnabe 17 mit einem Klemmkonus 14a, der durch Festziehen der in der Klemmnabe angeordneten sechs Klemmschrauben einen Pressdruck auf das Innenrohr 11 ausübt und dieses dadurch in der gewünschten Längeneinstellung fixiert. Im Schnitt der 2a entlang der Schnittlinie A-A der 2 ist ersichtlich, dass der Klemmkonus 19 das Innenrohr 11 vollständig umhüllt. 2 shows a clamping hub 17 with a clamping cone 14a , By tightening the arranged in the clamping hub six clamping screws a pressing pressure on the inner tube 11 exercises and this in the desired Längeneinstel fixed. On average, the 2a along the section line AA of 2 it can be seen that the clamping cone 19 the inner tube 11 completely wrapped.

Die dem Innenrohr abgewandte Seite der Klemmnabe 17 liegt in einstückiger Ausführungsform mit dem Aussenrohr 10 vor.The side facing away from the inner tube of the clamping hub 17 lies in one-piece embodiment with the outer tube 10 in front.

Die 3 zeigt eine Gelenkwelle mit einer Klemmnabe 18, in der ein Klemmring 14 angeordnet ist. Die im Schnitt der 3a entlang der Schnittlinie A-A der 3 dargestellten vier Klemmschrauben erzeugen beim Festziehen einen Pressdruck auf den Klemmring 14 und fixieren dadurch das Innenrohr 11 in der gewünschten Längeneinstellung. Die Klemmschrauben sind radial innerhalb dar Klemmnabe 18 angeordnet.The 3 shows a propeller shaft with a clamping hub 18 in which a clamping ring 14 is arranged. The average of the 3a along the section line AA of 3 When tightened, four illustrated clamping screws produce a pressing pressure on the clamping ring 14 and thereby fix the inner tube 11 in the desired length setting. The clamping screws are radially inside the clamping hub 18 arranged.

Auch diese Anordnung ermöglicht eine schlag- und spielfreie Übertragung des Drehmoments.Also this arrangement allows a shock and play-free transmission of torque.
