Description

Die vorliegende Erfindung betrifft eine Lenkvorrichtung für ein Kraftfahrzeug mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a steering device for a motor vehicle with the features of the preamble of claim 1.

Derartige Lenkvorrichtungen sind als elektrische Servolenkungen beispielsweise aus der US 3,983,953 bekannt. Dort treibt ein Antriebsmotor eine Gewindespindel an, die wiederum über eine Verzahnung als Teil eines Getriebes mittelbar mit den lenkbaren Rädern des Fahrzeugs in Verbindung steht. Der Antriebsmotor dient als Servomotor und liefert im Betriebe eine für die leichtgängige Bedienung der Lenkung erforderliche Lenkhilfskraft.Such steering devices are electrical Power steering systems, for example, from US 3,983,953 known. A drive motor drives one there Threaded spindle, which in turn has a toothing as Part of a transmission indirectly with the steerable wheels of the vehicle is connected. The drive motor serves as a servo motor and provides one for the company smooth operation of the steering required Power steering assist.

Bei derartigen Lenkungen ist das Getriebe, insbesondere die Spindel, nicht gedämpft, so daß Rückwirkungen das Getriebe unmittelbar belasten. Derartige Rückwirkungen treten insbesondere bei einem Endanschlag der Lenkung auf, bei dem die Lenkung in sehr kurzer Zeit zum Stillstand kommt. Das Trägheitsmoment des Motors wirkt dabei auf das Getriebe, dessen Belastungen hierbei etwa doppelt so hoch sind wie die im Fahrbetrieb auftretenden Maximalbelastungen.In such steering systems, the transmission is particularly the spindle, not damped, so that repercussions the  Load the transmission immediately. Such repercussions occur in particular at a steering stop on, where the steering to in a very short time Standstill comes. The moment of inertia of the motor acts thereby on the gearbox, the loads of which are about are twice as high as those that occur during driving Maximum loads.

Es ist deshalb Aufgabe der vorliegenden Erfindung, diese Belastungen, die auch auf den Antriebsmotor durchgreifen können, zu reduzieren. Diese Aufgabe wird von einer Lenkvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.It is therefore an object of the present invention Loads that also affect the drive motor can reduce. This task is done by a Steering device with the features of claim 1 solved.

Weil die Spindel in Wälzlagern gelagert ist, von denen wenigstens eines axial und/oder radial gegenüber dem Gehäuse beweglich ist, kann die Spindel gegenüber dem Gehäuse Axial- oder Radialbewegungen von geringer Amplitude ausführen. Die durch die Störungseinflüsse bewegte Masse wird dadurch verkleinert. Hierdurch reduzieren sich die mechanischen Belastungen der beteiligten Bauelemente.Because the spindle is mounted in roller bearings, of which at least one axially and / or radially opposite the Housing is movable, the spindle can against the Housing axial or radial movements of less Execute amplitude. The caused by the interference moving mass is thereby reduced. hereby reduce the mechanical loads on the components involved.

Vorzugsweise weisen die Lager jeweils eine äußere Lagerschale, eine innere Lagerschale und eine Anzahl von Wälzkörpern auf, wobei die äußeren Lagerschalen eine Einfassung aus einem gummiplastischen Werkstoff aufweisen. Um eine trotz der federnd beweglichen Lagerung definierte Ruheposition der Spindel zu erzielen, sind die Lager vorzugsweise vorgespannt montiert, indem insbesondere die Lagersitze in dem Gehäuse nicht koaxial ausgerichtet sind.The bearings preferably each have an outer one Bearing shell, an inner bearing shell and a number of Rolling bodies on, the outer bearing shells a Edging made of a rubber-plastic material exhibit. In spite of the resiliently movable bearing to achieve the defined rest position of the spindle are Bearing preferably mounted preloaded by especially the bearing seats in the housing are not coaxial are aligned.

Besonders geeignet als Lager sind Axialschrägkugellager oder Axialschrägnadellager. Diese können sowohl axial als auch radial auftretende Kräfte besonders gut aufnehmen. Axial angular contact ball bearings are particularly suitable as bearings or axial angular contact needle bearings. These can be both axial absorb radial forces particularly well.  

Eine Entkopplung der im Gehäuse geringfügig beweglichen Spindel von dem Antriebsmotor wird vorzugsweise dadurch erreicht, daß der Antriebsmotor mittels einer elastischen Kupplung im wesentlichen drehfest mit der Welle gekoppelt ist. Der Antriebsmotor ist dabei mit seiner Abtriebswelle vorzugsweise koaxial zu der Spindel ausgerichtet.A decoupling of the slightly movable in the housing Spindle from the drive motor is preferably thereby achieved that the drive motor by means of an elastic Coupling essentially coupled to the shaft in a rotationally fixed manner is. The drive motor is with its output shaft preferably aligned coaxially to the spindle.

Die Lenkung ist vorzugsweise von der Bauart einer elektrischen Servolenkung. Alternativ kann sie von der Bauart einer elektrischen Steer-by-Wire-Lenkung sein.The steering is preferably of the type one electric power steering. Alternatively, it can be from the Electric steer-by-wire steering.

Es ist weiter Aufgabe der vorliegenden Erfindung, ein Lager für die Lagerung einer im Gehäuse geringfügig beweglich zu lagernden Spindel zu schaffen. Diese Aufgabe wird von einem Axialschrägwälzlager mit den Merkmalen des Anspruchs 10 gelöst. Weil die äußere Lagerschale eine radiale und/oder axiale gummielastische Einfassung aufweist, kann das Lager gegenüber dem Gehäuse die erforderlichen Bewegungen ausführen.It is a further object of the present invention Bearings for storing one in the housing slightly to create a moveable spindle. This task is supported by an axial angular contact roller bearing with the characteristics of Claim 10 solved. Because the outer bearing shell is one radial and / or axial rubber-elastic border has, the bearing relative to the housing make the required movements.

Schließlich wird die erstgenannte Aufgabe durch die Verwendung eines mit gummielastischer Einfassung versehenen Axialschrägwälzlagers zur Lagerung einer Welle in einer elektrischen Lenkvorrichtung gelöst.Finally, the first task is accomplished by the Use one with rubber-elastic edging Axial angular contact roller bearing for supporting a shaft solved in an electric steering device.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. Es zeigtThe following is an embodiment of the invention described with reference to the drawing. It shows

Fig. 1 einen Ausschnitt aus einer elektrischen Lenkvorrichtung im Bereich der Spindel in einem Querschnitt parallel zur Axialrichtung. Fig. 1 shows a section of an electric steering device in the region of the spindle in a cross section parallel to the axial direction.

In der Fig. 1 ist eine in einem Gehäuse 1 gelagerte Welle oder Spindel 2 dargestellt, die um eine Achse 3 drehbar ist. Die Spindel 2 weist hierzu zwei voneinander wegweisende kegelförmige Stützflächen 4 auf, die im Bereich einstückig an die Spindel 2 angeformter Bereiche 5 größeren Durchmessers rotationssymmetrisch zur Achse 3 ausgebildet sind. Zwischen den Bereichen 5 trägt die Spindel 2 eine schraubenförmige Verzahnung 6, die zum Antrieb eines weiteren, nicht dargestellten Getriebeelements dient.In Fig. 1 a mounted in a housing 1 shaft or spindle 2 is shown, which is rotatable about an axis 3. For this purpose, the spindle 2 has two conical support surfaces 4 pointing away from one another, which are formed in the region of regions 5 of larger diameter which are integrally formed on the spindle 2 and are rotationally symmetrical to the axis 3 . Between the areas 5 , the spindle 2 carries a helical toothing 6 , which serves to drive a further gear element, not shown.

Das Gehäuse 1 weist weiter an zwei sich gegenüberliegenden Stirnflächen 7 eines im wesentlichen zylindrischen Innenraums 8 Lagersitze 9 für zwei die Lagerung der Spindel 2 bewirkende Wälzlager 10 auf.The housing 1 also has bearing seats 9 for two roller bearings 10 which effect the bearing of the spindle 2 on two opposite end faces 7 of an essentially cylindrical interior 8 .

Die Wälzlager 10 sind ihrerseits gegenüber den Lagersitzen 9 sowohl in Axialrichtung als auch in Radialrichtung mit einer Einfassung 11 aus einem gummielastischen Material versehen. Die Wälzlager 10 stützen sich dabei jeweils mit einer Außenschale 12 gegen die Einfassung 11 ab. Im übrigen sind die Wälzlager in an sich bekannter Weise ausgebildet, beispielsweise in der Bauform eines Axialschrägnadellagers.The roller bearings 10 are in turn provided with a border 11 made of a rubber-elastic material in relation to the bearing seats 9 both in the axial direction and in the radial direction. The roller bearings 10 are each supported with an outer shell 12 against the mount 11 . Otherwise, the rolling bearings are designed in a manner known per se, for example in the form of an axial angular contact needle bearing.

Ein eingangsseitiger Wellenstumpf 13 der Spindel 2 steht mit einer Abtriebswelle 14 eines nicht dargestellten Servomotors drehfest in Verbindung. Dabei ist die Kopplung zwischen der Abtriebswelle 14 des Servomotors und dem Wellenstumpf 13 von einer in geringem Umfang flexiblen Kupplung 15 bewirkt, die wiederum über elastische Elemente 16 Relativbewegungen zwischen der Abtriebswelle 14 und dem Wellenstumpf 13 erlaubt.An input-side stub shaft 13 of the spindle 2 is connected in a rotationally fixed manner to an output shaft 14 of a servomotor, not shown. The coupling between the output shaft 14 of the servo motor and the stub shaft 13 is effected by a coupling 15 which is flexible to a small extent and which in turn allows relative movements between the output shaft 14 and the stub shaft 13 via elastic elements 16 .

In der Praxis und insbesondere im Fahrbetrieb können Rückwirkungen der gelenkten Räder über die nicht dargestellten Komponenten des Lenkgetriebes auf die Verzahnung 6 der Spindel 2 einwirken. Diese Rückwirkungen bewirken radial und axial auf die Spindel 2 einwirkende Kräfte, die durch Verformung der Einfassungen 11 aufgenommen und letztlich gegenüber dem Gehäuse 1 sowie gegenüber der Motorwelle 14 gedämpft werden. Die Belastungen der Lager 10 und der übrigen, mit dem Gehäuse 1 verbundenen Komponenten, die nicht dargestellt sind, werden dadurch erheblich reduziert. Im Endeffekt kann damit auch die Dimensionierung der Lager 10 verringert werden. Etwaige im Betrieb auftretende Verlagerungen der Spindel 2 gegenüber dem Gehäuse 1 und damit gegenüber der Abtriebswelle 14 des Servomotors werden auch von der Kupplung 15 kompensiert. Diese Kupplung erlaubt sowohl translatorische Bewegungen der Spindel 2 als auch Verkippungen der Achse 3 gegenüber der entsprechenden Achse der Abtriebswelle 14.In practice and in particular when driving, reactions of the steered wheels can act on the toothing 6 of the spindle 2 via the components of the steering gear, not shown. These reactions cause radial and axial forces acting on the spindle 2 , which are absorbed by deformation of the mounts 11 and ultimately dampened with respect to the housing 1 and the motor shaft 14 . The loads on the bearings 10 and the other components connected to the housing 1 , which are not shown, are thereby considerably reduced. In the end, the dimensioning of the bearings 10 can also be reduced. Any displacements of the spindle 2 with respect to the housing 1 and thus with respect to the output shaft 14 of the servomotor that occur during operation are also compensated for by the clutch 15 . This coupling allows translatory movements of the spindle 2 as well as tilting of the axis 3 with respect to the corresponding axis of the output shaft 14 .

Als weiteren Bestandteil der Erfindung kann das jeweilige Wälzlager 10 im Bereich seiner äußeren Lagerschale 12 mit der Einfassung 11 verbunden werden. Es entsteht somit ein als einheitliches Bauelement montierbares Wälzlager mit angeformtem Federelement zur Abfederung von Axial- und Radialkräften. Derartige neue Lager können auch bei anderen Konstellationen Anwendung finden, in denen eine Welle gegenüber einem Gehäuse in geringem Maße beweglich gelagert werden soll.As a further component of the invention, the respective roller bearing 10 can be connected to the casing 11 in the region of its outer bearing shell 12 . The result is a rolling bearing that can be assembled as a unitary component with a molded-on spring element for cushioning axial and radial forces. Such new bearings can also be used in other constellations in which a shaft is to be mounted to be movable to a small extent relative to a housing.

Die Einfassungen 11 können je nach Bedarf aus einem gummi- oder kautschukähnlichen Werkstoff gefertigt werden, während auch rein synthetische Werkstoffe möglich sind. Je nach Anwendungsfall kann das Elastizitätsmodul und die Eigendämpfung des jeweiligen Materials gewählt werden, um den Anforderungen möglichst gut entsprechen zu können.The surrounds 11 can be made of a rubber or rubber-like material as required, while purely synthetic materials are also possible. Depending on the application, the modulus of elasticity and the inherent damping of the respective material can be selected in order to meet the requirements as well as possible.
