Description
Drelifeste Verbindung zweier teleskopartig ineinander verschiebbarer Wellen Die Erfindung bezieht sich auf eine drehfeste Verbindung zweier teleskopartig ineinander verschiebbarer Wellen, insbesondere zweier Lenkspindelteile in Kraftwagen, die aus Wälskörpern,vorzugsweise Kugeln, besteht, die in Axialnuten der einen Welle und in Axialnuten der anderen Welle gelagert sind, welche die eine Welle im Bereich der Axialnuten umfaßt. Non-floating connection of two telescopically slidable one into the other Shafts The invention relates to a rotationally fixed connection of two telescopic mutually displaceable shafts, in particular two steering spindle parts in motor vehicles, which consists of rolling bodies, preferably balls, which are in axial grooves of one shaft and are mounted in axial grooves of the other shaft, which one shaft in the area which includes axial grooves.
Verbindungen dieser Art zeichnen sich durch eine besondere Leichtgällgigkeit bei Längsverschiebungen aus. Auch die Spielfreiheit dieser Verbindungen bei der Übertragung von Drehkröften ist ein Vorzug. Leider bleibt die Spielfreiheit wegen des Verschleißes der als Wälzkörperbahnen ausgebildeten Axialnuten nicht auf die Dauer erhalten.Connections of this kind are characterized by a particular ease of use in the case of longitudinal shifts. The freedom of play of these connections in the Transmission of torque is a preference. Unfortunately, the freedom of play remains because of the wear of the axial grooves designed as rolling element tracks does not affect the Preserved duration.
Der Erfindung liegt die Aufgabe zugrunde eine Verbindung zu schaffen, bei der das Speil im Laufe der Zeit nicht größer wird.The invention is based on the object of creating a connection where the game doesn't get bigger over time.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß der mit Axialnuten versehene, die eine Welle umfassende Teil der anderen Welle aus einer Hülse besteht, die sit Vorspannung federnd an den Wälzkörpern anliegt. Durch das federnde Anliegen werden die Wälzkörper auch nach einem Berschleißikörperbahnen noch spielfrei geführt.The object is achieved according to the invention in that the provided with axial grooves, the part comprising a shaft the other Shaft consists of a sleeve which is resiliently applied to the rolling elements sit preload. Due to the resilient contact, the rolling elements are also subject to wear and tear still run free of play.
In vorteilhafter Ausgestaltung des Gegenstandes der Erfindung können die Wälzkörper aus in einem Käfig geführten Kugeln bestehen.In an advantageous embodiment of the subject matter of the invention can the rolling elements consist of balls guided in a cage.
In der Zeichnung ist eine drehfeste Verbindung zwischen zwei teleskopartig ineinander vorschiebbaren Wellen dargestellt.In the drawing, a non-rotatable connection between two is telescopic Shafts that can be pushed into one another are shown.
Es zeigen: Fig. 1 eine Gesamtansicht der Verbindung und Fig.2 in größerem Maßstab einen Querschnitt durch die Verbindung nach der Linie 11-11 aus Fig. 1.They show: FIG. 1 an overall view of the connection and FIG. 2 in a larger view Scale shows a cross-section through the connection along the line 11-11 from FIG. 1.
nach Fig. 1 ist bei einer Kraftwagenlenkung der Lenkspindelteil 1 teleskopartig verschiebbar in dem Lenkspiendelteil 2 angeordnet.According to FIG. 1, the steering spindle part 1 is in the case of a motor vehicle steering system Arranged telescopically displaceable in the steering column part 2.
Zur drehfesten Verbindung der Lenkspindelteile 1,2 und für eine reibungsarme Längsverstellbarkei*t dieser Teile sind vier Reihen von Kugeln 3 voigesehen, die einerseits in als Kugelbahnen ausgebildeten Axialnuten 4 in dem Lenkspindelteil 1 und andererseits in als Kugelbahnen dienenden Axialnuten 3 geführt sind1 die von der axial an den Lenkepindelteil ansesetsten, den Len40pindelteil umfassenden Hülse 6 gebildet werden. In einander zugeordneten Axialnuten 5,6 liegen in Achsrichtung hintereinander zwei Kugeln 3. Alle Kugeln sind in einem Käfig 7 geführt.For non-rotatable connection of the steering spindle parts 1, 2 and for low-friction Longitudinal adjustability of these parts are four rows of balls 3, the on the one hand in axial grooves 4 designed as ball tracks in the steering spindle part 1 and on the other hand in axial grooves 3 serving as ball tracks are guided by the sleeve that is axially attached to the steering spindle part and encompasses the steering spindle part 6 are formed. Axial grooves 5, 6 assigned to one another lie in the axial direction two balls 3 in a row. All balls are guided in a cage 7.
Wie näher aus kig. 2 hervorgeht, liegen Jeweils zwei Reihen von Kugeln 3 einander gegenüber.How closer from kig. 2 shows, there are always two rows of balls 3 opposite each other.
Die llülse 6 ist derart ausgebildet, daß sie mit Vorspannung federnd an den lçugeln 3 anliegt. Dadurch werden die Kugeln 3 über die Axialnuten 5 der Hülse 6 gegen die Axialnuten 4 des Lenkspindelteiles 1 gedrückt. Sollten im Laufe der Zeit die Axialnuten verschleißen, bleibt der federnde Andruck der llülse 6 auf die Kugeln 3 erhalten. Die Verbindung bleibt spielfrei.The sleeve 6 is designed in such a way that it is resilient with bias on the balls 3 rests. As a result, the balls 3 on the axial grooves 5 of the Sleeve 6 pressed against the axial grooves 4 of the steering spindle part 1. Should be in the course The axial grooves wear out over time, the resilient pressure of the llülse 6 remains on get the 3 balls. The connection remains backlash-free.
