Abstract

The mechanism (10) has a coupling mechanism (13) provided between a steering gear (12) and a steering column (11). The steering column and a shaft of the steering gear are fastened at a universal joint (15) in the coupling mechanism. The steering column is supported with a swash bearing i.e. needle bearing, in the coupling mechanism.

Description

Die Erfindung betrifft eine Lenkung, insbesondere für ein Kraftfahrzeug, mit einem Lenkgetriebe und einer Lenksäule.The The invention relates to a steering, in particular for a motor vehicle, with a Steering gear and a steering column.

Üblicherweise sind das Lenkgetriebe und die Lenksäule von den Einbauabmessungen aufeinander abgestimmt. Deshalb müssen die Dimensionen des Lenkgetriebes oder der Lenksäule aneinander angepasst werden. Da die Abstimmung der Einbauabmessungen durch den umgebenden Bauraum beeinflusst wird, kann es Probleme geben bei der Verbindung von Lenkgetriebe und Lenksäule. Besonders gravierend ist dieses Problem, wenn bereits bestehende Lenksäulen und Lenkgetriebe von einer Linkslenkung für eine Rechtslenkung verwendet werden sollen.Usually The steering gear and the steering column are of the installation dimensions coordinated. Therefore, the dimensions of the steering gear or the steering column be adapted to each other. Since the vote of the installation dimensions It can be a problem because of the surrounding space give in the connection of steering gear and steering column. Especially serious is this problem if already existing steering columns and Steering gear used by a left-hand drive for right-hand steering should be.

Die Erfindung hat die Aufgabe bei einer Lenkung der eingangs genannten Art die Verbindung von Lenkgetriebe und Lenksäule auch bei unterschiedlichen Einbauabmessungen sicherzustellen.The Invention has the object in a steering of the aforementioned Type the connection of steering gear and steering column even with different Ensure installation dimensions.

Die Erfindung löst die gestellte Aufgabe mit einer Lenkung der eingangs genannten Art, bei der zwischen dem Lenkgetriebe und der Lenksäule eine Kupplungseinrichtung vorgesehen ist. Somit können zukünftig das Lenkgetriebe und die Lenksäule unter Beibehaltung von Standardabmessungen miteinander verbunden werden, auch wenn unterschiedliche Einbauabmessungen im Fahrzeug vorliegen.The Invention solves the stated object with a steering of the type mentioned, at the between the steering gear and the steering column a coupling device is provided. Thus, in the future, the Steering gear and the steering column while maintaining standard dimensions be, even if different installation dimensions in the vehicle available.

Die Kupplungseinrichtung kann mit einem Kreuzgelenk ausgerüstet sein. Auf diese Weise können die in der Regel nicht in einer Linie miteinander fluchtenden Längsachsen der Lenksäule und des Lenkgetriebes aufeinander abgestimmt werden.The Coupling device may be equipped with a universal joint. That way you can the generally not aligned in a line longitudinal axes the steering column and the steering gear to be matched.

Um eine Verbindung zwischen dem Lenkgetriebe und der Lenksäule herstellen zu können, kann an dem Kreuzgelenk einenends die Lenksäule und anderenends die Welle des Lenkgetriebes angebunden sein.Around make a connection between the steering gear and the steering column to be able to can at the universal joint at one end the steering column and the other end the shaft be connected to the steering gear.

Da die Lenksäule in der Regel mindestens zwei Kreuzgelenke aufweist, wirken auf die Kupplungseinrichtung während des Lenkvorgangs hohe Radialkräfte, die versuchen die Kupplungseinrichtung zu verschieben. Zum Ausgleich der hohen Radialkräfte und zum Ausgleich eines Versatzes, der zwischen beiden Ebenen, in welchen die Längsachse des Lenkgetriebes und die Längsachse der Lenksäule liegen, besteht, kann die Lenksäule in der Kupplungseinrichtung mit einem Taumellager gelagert sein, um taumelnde Ausgleichsbewegungen durchführen zu können.There the steering column usually has at least two universal joints, act on the Coupling device during the steering operation high radial forces, trying to move the coupling device. To compensate the high radial forces and to compensate for an offset between two levels, in which the longitudinal axis of Steering gear and the longitudinal axis the steering column lie, the steering column can be stored in the coupling device with a swash bearing, to perform staggering compensatory movements.

Kostengünstig für die Verwirklichung des Taumellagers ist ein Nadellager. Außerdem hat sich der Einsatz des Nadellagers in der Praxis sehr gut bewährt. Es ist jedoch auch zweckmäßig ein Gleit- oder Rollenlager zu verwenden.Cost effective for the realization of the swash bearing is a needle bearing. In addition, the use has the needle bearing in practice very well proven. However, it is also appropriate Use sliding or roller bearings.

Die Kupplungseinrichtung kann mit einem Gehäuse versehen sein. Das Gehäuse hat die Aufgabe während des Lenkvorgangs die Radialkräfte, welche von der Lenksäule auf das im Gehäuse angeordnete Taumellager übertragen werden, aufzunehmen und an das Lenkgetriebe weiterzuleiten.The Coupling device may be provided with a housing. The case has the task during the steering process the radial forces, which of the steering column on the inside of the case transferred arranged swash bearing be absorbed and forward to the steering gear.

Besonders deutlich kommen die erfindungsgemäßen Vorteile zum tragen, wenn die Lenkung eine Rechtslenkung ist.Especially clearly the benefits of the invention come to bear, if the steering is a right-hand drive.

Die Kupplungseinrichtung kann mit bereits bestehenden Lenkgetrieben und Lenksäulen kombiniert werden. So können durch die Kupplungseinrichtung das bestehende Lenkgetriebe und die bestehende Lenksäule einer Linkslenkung ohne Änderungen an den Abmessungen des Lenkgetriebes und der Lenksäule vornehmen zu müssen auch für eine Rechtslenkung miteinander kombiniert werden.The Coupling device can with existing steering gears and steering columns be combined. So can by the coupling means the existing steering gear and the existing steering column a left-hand drive without changes on the dimensions of the steering gear and the steering column to have to also for a right-hand drive can be combined.

Nachfolgend werden verschiedene Ausführungsbeispiele der erfindungsgemäßen Lenkung anhand der beiliegenden Zeichnungen näher erläutert.following Be different embodiments the steering system according to the invention explained in more detail with reference to the accompanying drawings.

Durch die Kupplungseinrichtung 13 werden also die Lenksäule 11 und das Lenkgetriebe 12 miteinander verbunden. Die Lenksäule 11 weist zwei Kreuzgelenke 15 auf, wobei das obere Kreuzgelenk nicht in der Figur dargestellt ist. 1 shows a steering 10 with a steering column 11 and a steering gear 12 , Between the steering column 11 and the steering gear 12 is a coupling device 13 arranged. By the coupling device 13 So are the steering column 11 and the steering gear 12 connected with each other. The steering column 11 has two universal joints 15 on, wherein the upper universal joint is not shown in the figure.

Die Kupplungseinrichtung 13 weist ein Kreuzgelenk 20 auf (siehe 2). An dem Kreuzgelenk 20 ist einenends die Lenksäule 11 und anderenends eine Welle 21 des Lenkgetriebes 12 angebunden.The coupling device 13 has a universal joint 20 on (see 2 ).
