Abstract

The cover which is in the form of a flexible bellows is specially used for universal linkages in motor car drives. The cover has a first sleeve at one end which fits over the driving part and a second sleeve which fits over the driven part. The first sleeve has a larger diameter than the second, to facilitate assembly of the cover. The first sleeve is provided with an internal lip which points radially inward and is an extension of the first bellows convolution. This lip prevents loss of lubricant from the linkage.

Gelenkschutzhülle aus elastischem WerkstoffJoint protection cover made of elastic material

Sie Erfindung bezieht sich auf eine Gelenkschutzhülle aus elastischem Werkstoff für umlaufende Gelenkteile, insbesondere für Antriebsgelenke von Kraftfahrzeugen, mit einem zur Befestigung am Antriebsgelenk dienenden ersten Bund und einem zur Befestigung an der Gelenkwelle dienenden zweiten Bund.The invention relates to a protective joint cover elastic material for rotating joint parts, in particular for drive joints of motor vehicles, with a for fastening to the drive joint serving first collar and a second collar serving for fastening to the articulated shaft Federation.

Solche beispielsweise aus der deutschen Gebrauchsmusterschrift 68 O95 59 bekannten Gelenkschutzhüllen haben die Aufgabe, die Antriebsgelenke vor Verschmutzung, Beschädigung und auch vor Schmiermittelverlusten zu schützen·Such for example from the German utility model 68 O95 59 known joint protective sleeves have the task of Drive joints from contamination, damage and also from To protect lubricant losses

Es hat sich herausgestellt, daß die im Antriebsgelenk vorhandenen Schmierstoffe nach einer relativ kurzen Betriebszeit das Antriebsgelenk verlassen und sich in der Gelenkschutzhülle versammeln. Eine zufriedenstellende Schmierung des Antriebsge-It has been found that the lubricants present in the drive joint after a relatively short operating time leave the drive joint and gather in the joint protection cover. Satisfactory lubrication of the drive

lenkes ist danach jedoch nicht mehr gewährleistet. Die Lebensdauer des Antriebsgelenkes wird herabgesetzt.steering is no longer guaranteed afterwards. The lifespan of the drive joint is reduced.

Aufgabe der Erfindung ist es, eine Gelenkschutzhülle der eingangs genannten Art so auszugestalten, daß die im Antriebsgelenk vorhandenen Schmierstoffe weitgehend daran gehindert werden, das Gelenk zu verlassen.The object of the invention is to design a protective joint cover of the type mentioned at the outset in such a way that the in the drive joint existing lubricants are largely prevented from leaving the joint.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß innerhalb der Gelenkschutzhülle unmittelbar hinter dem zur Befestigung am Antriebsgelenk dienenden ersten Bund eine radial nach innen gestellte, umlaufende Lippe vorgesehen ist. Grundsätzlich ist es bekannt, innerhalb einer Gelenkschutzhülle eine radial nach innen gestellte, umlaufende Lippe vorzusehen. Diese aus der deutschen Gebrauchsmusterschrift 68 093 59 bekannte Lippe hat jedoch eine andere Aufgabe als die erfindungsgemäß vorgesehene Lippe. Sie soll verhindern, daß sich der Faltenbalg während des Betriebes infolge der Zentrifugalkräfte verformt und dadurch vorzeitig unbrauchbar wird.This object is achieved in that within the joint protective sleeve immediately behind the for attachment to Drive joint serving first collar a radially inwardly positioned, circumferential lip is provided. Basically it is known to provide a radially inwardly positioned, circumferential lip within a protective joint cover. This from the German However, utility model 68 093 59 known lip has one different task than the lip provided according to the invention. It is intended to prevent the bellows from moving during operation deformed as a result of centrifugal forces and thus prematurely unusable.

Darüber hinaus ist die bekannte Lippe an anderer Stelle vorgesehen als die erfindungsgemäße Lippe. Bei der bekannten Anordnung ist die Lippe als in den Faltenbalg hineinragender Fortsatz einer Falte ausgebildet, wo/hingegen die erfindungsgemäße Lippe unmittelbar hinter dem zur Befestigung am Antriebsgelenk dienenden ersten Bund, also bereits vor den Falten der Gelenkschutzhülle angeordnet ist.In addition, the well-known lip is provided elsewhere than the lip of the invention. In the known arrangement, the lip is an extension projecting into the bellows Wrinkle formed, where / on the other hand the lip according to the invention directly behind the first collar serving for attachment to the drive joint, that is to say already arranged in front of the folds of the joint protective cover is.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung erläutert. In der einzigen Figur ist eine Gelenkschutzhülle aus elastischem Werkstoff nach Art eines Faltenbalges dargestellt. Diese Gelenkschutzhülle enthält einen ersten Bund 1, der zur Befestigung der Gelenkschutzhülle am Antriebsgelenk des Kraftfahrzeuges dient, und einen zweiten Bund 3, der zurThe invention is explained on the basis of an exemplary embodiment shown in the drawing. In the single figure is a protective joint cover shown made of elastic material like a bellows. This protective joint cover contains a first Bund 1, which is used to attach the protective hinge to the drive joint of the motor vehicle, and a second collar 3, which is used for

409886/0692409886/0692

Befestigung der Gelenkschutzhülle an der Gelenkwelle des Kraftfahrzeuges dient. Der erste Bund 1 besitzt einen größeren und der zweite Bund 3 einen kleineren Durchmesser. Unmittelbar hinter dem ersten Bund 1 ist eine radial nach innen gestellte, umlaufende Lippe 2 vorgesehen, die veitgehend verhindert, daß der in das Antriebsgelenk eingefüllte Schmierstoff dieses Gelenk verläßt. Das hat zur Folge, daß der verwendete Schmierstoff besser ausgenutzt wird und daß darüber hinaus sichergestellt ist, daß das Antriebsgelenk ständig ausreichend geschmiert wird. Die Lebensdauer des Antriebsgelenkes wird demnach erhöht. Attachment of the joint protection sleeve to the cardan shaft of the motor vehicle is used. The first fret 1 has a larger and the second collar 3 has a smaller diameter. Immediately behind the first collar 1 is a radially inwardly placed, circumferential Lip 2 is provided, which largely prevents the lubricant filled into the drive joint from leaving this joint. As a result, the lubricant used is better utilized and that it is also ensured that the drive joint is constantly adequately lubricated. The service life of the drive joint is increased accordingly.

Die Erfindung wurde anhand einer Gelenkschutzhülle in Form eines Faltenbalgeβ erläutert. Grundsätzlich ist ihre Anwendung jedoch auch bei anders ausgestalteten Gelenkschutzhüllen möglich.The invention was explained on the basis of a protective joint cover in the form of a bellows. However, their application is fundamental also possible with differently designed joint protection sleeves.
