Description

Vorrichtung zum Sperren der Drehbewegung einer Lenkspindel eines Kraftfahrzeuges Device for blocking the rotational movement of a steering spindle of a motor vehicle
Die Erfindung betrifft eine Vorrichtung zum Sperren der Drehbewegung der Lenkspindel eines Kraftfahrzeuges durch ein Klemmgesperre mit achsparallelen Rollen, die zwischen einer zylindrischen Laufbahn und zur Laufbahn schrägenThe invention relates to a device for blocking the rotational movement of the steering spindle of a motor vehicle by means of a locking mechanism with axially parallel rollers which are inclined between a cylindrical raceway and the raceway
Klemmflächen die Lenkspindel in beiden Drehrichtungen festklemmen und in einem um die Lenkspindel verdrehbaren koaxialen Käfig geführt sind, der durch die Lenkspindel in beiden Drehrichtungen jeweils in eine der beiden Klemmstellungen mitschleppbar und in einer zwischen beiden Klemmstellungen liegenden Mittelstellung feststellbar ist, in der die Rollen die Lenkspindel freigeben.Clamping surfaces clamp the steering spindle in both directions of rotation and are guided in a coaxial cage that can be rotated around the steering spindle, which can be towed by the steering spindle in both directions of rotation into one of the two clamping positions and in a central position between the two clamping positions, in which the rollers are the steering spindle release.
Eine derartige Sperrvorrichtung ist aus der FR-A 24 56 644 bekannt. Bei dieser Vorrichtung nimmt der Käfig, wenn er nicht festgestellt ist, unterschiedliche Stellungen ein, da der Reibschluß zwischen Lenkspindel und Käfig keinen gleichbleibenden Wert hat. Insbesondere durch Temperaturdifferenzen ändert sich der Reibschluß erheblich. Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art derart zu verbessern, daß eine gleich mäßige exakte Mitnahme des Käfigs durch die Spindel erreicht wird.Such a locking device is known from FR-A 24 56 644. In this device, the cage assumes different positions if it is not ascertained, since the frictional connection between the steering spindle and the cage has no constant value. The frictional connection changes considerably, in particular due to temperature differences. The object of the invention is to improve a device of the type mentioned in such a way that a uniform exact entrainment of the cage is achieved by the spindle.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß alle Rollen außen von mindestens einem zur Spindel koaxialen, elastischen Ring umgeben sind, der die Rollen zur Lenkspindel hin federnd beaufschlagt.This object is achieved in that all the rollers are surrounded on the outside by at least one coaxial to the spindle, elastic ring which resiliently acts on the rollers towards the steering spindle.
Der erfindungsgemäße elastische Ring drückt die Rollen stets mit gleicher Kraft gegen die Lenkspindel, so daß ein exakter und ständig gleichmäßiger Reibschluß zwischen Käfig und Spindel gewährleistet ist. Damit sind die Stellungen des Käfigs auf der Spindel genau bestimmt.The elastic ring according to the invention always presses the rollers with the same force against the steering spindle, so that an exact and constantly uniform frictional engagement between the cage and the spindle is ensured. The positions of the cage on the spindle are thus precisely determined.
Die Vorrichtung baut in axialer und radialer Richtung sehr klein, ist einfach und preiswert in der Herstellung und leicht zu montieren.The device is very small in the axial and radial direction, is simple and inexpensive to manufacture and easy to assemble.
Besonders preiswert und platzsparend ist der Ring dann, wenn er aus Gummi oder elastischem Kunststoff besteht. Eine konstruktiv sehr einfache Ausführung wird dadurch geschaffen, daß die Rollen über die Käfigaußenseite vorstehen und der Ring über der Käfigaußenseite liegt. Dabei können Käfigaύßenseite und Ring noch von einem weiteren Käfigteil außen umgeben sein.The ring is particularly inexpensive and space-saving if it is made of rubber or elastic plastic. A structurally very simple design is created in that the rollers protrude beyond the outside of the cage and the ring lies over the outside of the cage. The outside of the cage and the ring can be surrounded by another part of the cage.
Eine sehr gleichmäßige Druckbeaufschlagung wird dann erreicht, wenn zu beiden Seiten eines äußeren, die Klemmflächen aufweisenden, feststehenden Klemmringes je ein elastischer Ring angeordnet ist.A very uniform pressurization is achieved if an elastic ring is arranged on each side of an outer, fixed clamping ring having the clamping surfaces.
Von Bedeutung ist es, daß der Käfig zwischen den beiden Klemmstellungen in einer Mittelstellung arretierbar ist, so daß während der Fahrt ein Festklemmen der Lenkspindel mit Sicherheit vermieden wird. Hierzu wird in der FR-A 2 456 644 vorgeschlagen, einen Bolzen in eine Ausnehmung des Käfigs einzubringen. Dieser Bolzen gelangt in diese Ausnehmung aber nur dann, wenn die Ausnehmung mit dem Bolzen fluchtet, so daß die Lenkspindel durch das Lenkrad so lange hin- und herbewegt werden muß, bis dieser Zustan eintritt.It is important that the cage between the two Clamping positions can be locked in a central position, so that jamming of the steering spindle is avoided with certainty while driving. For this purpose, it is proposed in FR-A 2 456 644 to insert a bolt into a recess in the cage. This bolt only gets into this recess when the recess is aligned with the bolt, so that the steering spindle has to be moved back and forth by the steering wheel until this condition occurs.
Hiergegen wird bei der erfindungsgemäßen Vorrichtung vorgeschlagen, daß der Käfig außen einen Vorsprung aufweist, der durch ein vom Lenkschloß gesteuertes Teil in eine Stellung zu bringen und arretierbar ist, in der der Käfig nicht sperrt. Damit erzeugt das Teil, das den Käfig arretiert, gleichzeitig auch die Lage des Käfigs, in der dieser nicht sperrt.In contrast, it is proposed in the device according to the invention that the cage has a projection on the outside, which can be brought into a position and locked by a part controlled by the steering lock, in which the cage does not lock. The part that locks the cage thus also creates the position of the cage in which it does not lock.
Vorzugsweise wird vorgeschlagen, daß ein vom Lenkschloß gesteuertes Teil den Käfig durch ein insbesondere doppeltes Keilgetriebe in die nicht klemmende Stellung stellt. Hierdurch wird eine besonders einfache und sichere Konstruktion geschaffen. Ferner wird vorgeschlagen, daß der Käfigvorsprung oder das vom Lenkschloß gesteuerte Teil eine Ausnehmung mit zwei Keilflächen aufweist, in die einIt is preferably proposed that a part controlled by the steering lock puts the cage into the non-clamping position by means of a double wedge gear in particular. This creates a particularly simple and safe construction. It is also proposed that the cage projection or the part controlled by the steering lock has a recess with two wedge surfaces into which a

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigen: Fig. 1 einen Schnitt durch die Vorrichtung quer zurAn embodiment of the invention is shown in the drawings and will be described in more detail below. Show it: Fig. 1 shows a section through the device transverse to

Fig. 3 einen Schnitt nach III-III in Fig. 2.3 shows a section according to III-III in FIG. 2.
Auf der Lenkspindel 1 eines Kraftfahrzeuges ist drehfest eine Buchse 2 befestigt. Der Außenmantel der Buchse 2 bildet eine zylindrische Laufbahn 3 für zylindrischeOn the steering shaft 1 of a motor vehicle, a socket 2 is rotatably attached. The outer jacket of the socket 2 forms a cylindrical raceway 3 for cylindrical
Rollen 4, die achsparallel zur Drehachse der Lenkspindel 1 liegen und regelmäßig um die Buchse 2 in einem Käfig 5 gelagert sind. Alternativ kann die Buchse 2 entfallen und der Mantel der Lenkspindel 1 die Laufbahn für die Rollen bilden.Rollers 4, which are axially parallel to the axis of rotation of the steering spindle 1 and are regularly mounted around the socket 2 in a cage 5. Alternatively, the socket 2 can be omitted and the jacket of the steering spindle 1 form the track for the rollers.
Der Käfig 5 ist außen von zwei elastischen Ringen 6 umgeben, die auf den Rollen 4 aufliegen und diese zur Lenkspindel 1 hin radial belasten. Diese Radialbelastung wird dadurch ermöglicht, daß die zwischen den Rollen 4 liegenden Abschnitte des Käfigs 5 in radialer Richtung eine geringere Dicke aufweisen als die Durchmesser der Rollen 4.The cage 5 is surrounded on the outside by two elastic rings 6 which rest on the rollers 4 and radially load them towards the steering spindle 1. This radial load is made possible by the fact that the sections of the cage 5 lying between the rollers 4 have a smaller thickness in the radial direction than the diameter of the rollers 4.
Der Käfig 5 ist von einem ringförmigen Käfigteil 5a, 5b koaxial im Abstand zum Käfig 5 umgeben, so daß in dem einen Ringraum 7 bildenden Abstand die elastischen Ringe 6 einliegen können. Dieser äußere Käfigteil ist in einen ringförmigen ersten Teil 5a aufgeteilt, der am Käfig 5 angeformt ist und in einen zweiten Teil 5b, der vcn der Stirnseite her auf den Käfig 5 aufgesetzt wird. Zwischen den Teilen 5a und 5b besteht ein ringnutenförmiger Abstand, in dem ein Klemmring 8 koaxial einliegt. Der Klemmring 8 reicht von außen in den Käfig 5 zwischen den beiden elastischen Ringen 6 so weit hinein, daß an seiner Innenwandung die Rollen 4 klemmend zur Anlage gelangen können. Hierzu bildet die Innenwandung gerade oder gebogene Ausnehmungen bzw. schräge, gerade oder gebogene Klemmflächen 9, die bei der in den Figuren gezeigten Mittelstellung des Käfigs 5 ausreichend Platz für die Rollen lassen und bei einem Drehen des Käfigs in beide Drehrichtungen. die Rollen zwischen dem drehfesten Klemmring 8 und der Laufbahn 3 verklemmen lassen.The cage 5 is surrounded by an annular cage part 5a, 5b coaxially at a distance from the cage 5, so that the elastic rings 6 can lie in the distance forming an annular space 7. This outer cage part is divided into an annular first part 5a, which is molded onto the cage 5, and into a second part 5b, which is placed on the cage 5 from the front side. Between the parts 5a and 5b there is an annular groove-shaped distance in which a clamping ring 8 lies coaxially. The clamping ring 8 extends from the outside into the cage 5 between the two elastic rings 6 so far that the rollers 4 can come to rest against the inner wall. For this purpose, the inner wall forms straight or curved recesses or oblique, straight or curved clamping surfaces 9, which leave sufficient space for the rollers in the central position of the cage 5 shown in the figures and when the cage is rotated in both directions of rotation. allow the rollers to jam between the non-rotatable clamping ring 8 and the raceway 3.
Am Käfigteil 5a ist ein radialer Vorsprung 10 angeformt, der an seiner Außenseite eine keilförmige AusnehmungA radial projection 10 is formed on the cage part 5a and has a wedge-shaped recess on its outside
11 besitzt, die klappsymmetrisch zu einem Radius der Lenkspindel zwei schräge Keilflächen 11a und 11b seitlich bildet. In die Ausnehmung 11 ist ein von einem nicht gezeigten Lenkschloß betätigter ßolzen 12 einfahrbar, dev an seinem der Lenkspindel 1 zugewandten Ende zwei Keilflächen 12a, 12b besitzt, die bei einer Mittelstellung des Käfigs 5 parallel zu den Flächen 11a und 11b liegen. Dir ßolzen11, which forms two inclined wedge surfaces 11a and 11b laterally symmetrically to a radius of the steering spindle. In the recess 11 is actuated by a steering lock, not shown, bolt 12 dev, dev has at its end facing the steering shaft 1 two wedge surfaces 12a, 12b, which are parallel to the surfaces 11a and 11b in a central position of the cage 5. Bolt you
12 kann auch achsparallel zur Lenkspindel angeordnet und in Längsrichtung beweglich sein, wobei dann die Ausnehmung 11 um 90º gedreht im Vorsprung 10 angeordnet sein muß. Zwischen der radialen und achsparallelen Stellung des Bolzens sind auch Zwischenstellungen möglich.12 can also be arranged axially parallel to the steering spindle and movable in the longitudinal direction, in which case the recess 11 must be arranged in the projection 10 rotated by 90 °. Intermediate positions are also possible between the radial and axially parallel position of the bolt.
Wenn der Bolzen 12 mit seiner der Lenkspindel zugewandten Spitze in die Ausnehmung 11 eingreift, ist der Käfig 5 in seiner Mittelstellung blockiert; so daß die Lenkspindel 1 sich frei drehen kann, ohne durch die Rollen 4 festgeklemmt zu werden. Diese Stellung erreicht der Bolzen 12 nur dann, wenn der Schlüssel in das Lenkschloß eingesteckt ist und durch Drehen des Zylinderkerns der Bolzen 12 in diese Lage geschoben wurde. Bei abgezogenem Schlüssel gelangt der Bolzen zumindest teilweise aus der Ausnehmung 11 heraus, so daß sich der Käfig begrenzt in beide Drehrichtungen bewegen kann. Aufgrund der durch die elastischen Ringe 6 erzeugten Reibung wird bei Drehen der Lenkspindel 1 der Käfig 5 in dieselbe Drehrichtung so weit mitgenommen, bis die Rollen zwischen den Klemmflächen 9 und der Laufbahn 3 sich verklemmen und damit ein weiteres Drehen der Lenkspindel verhindern. Um diese radial nach außen wirkenden, durch die Rollen erzeugten Kräfte aufzunehmen, ist der Klemmring 8 aus einem sehr Widerstandsfähigen Stahl hergestellt.When the bolt 12 engages in the recess 11 with its tip facing the steering spindle, the cage 5 is blocked in its central position; so that the steering shaft 1 can rotate freely without being jammed by the rollers 4. This position reaches the bolt 12 only when the key is inserted in the steering lock and by turning the cylinder core Bolt 12 was pushed into this position. When the key is removed, the bolt at least partially comes out of the recess 11, so that the cage can move to a limited extent in both directions of rotation. Due to the friction generated by the elastic rings 6, when the steering spindle 1 is rotated, the cage 5 is carried along in the same direction of rotation until the rollers jam between the clamping surfaces 9 and the raceway 3 and thus prevent the steering spindle from rotating further. In order to absorb these radially outwardly acting forces generated by the rollers, the clamping ring 8 is made of a very resistant steel.
Der Drehwinkel zwischen den beiden Klemmstellungen des Käfigs beträgt nur 6º. In beiden Klemmstellungen desThe angle of rotation between the two clamping positions of the cage is only 6º. In both clamping positions of the
Käfigs 5 ist die Ausnehmung 11 gegenüber der Spitze des Bolzens 12 nur so weit verdreht, daß die Bolzenspitze immer noch zum Teil in die Ausnehmung eindringen kann und eine Keilfläche des Bolzens an einer Keilfläche der Ausnehmung zur Anlage gelangt, so daß ein weiteres Einschieben des Bolzens 12 in die Ausnehmung 11 einr Bewegung des Käfigs aufgrund des Keilgetriebes zur Mittelstellung hin erzeugt.Cage 5, the recess 11 is rotated only so far with respect to the tip of the bolt 12 that the bolt tip can still partially penetrate into the recess and a wedge surface of the bolt comes into contact with a wedge surface of the recess, so that the bolt can be inserted further 12 in the recess 11 generates a movement of the cage due to the wedge gear toward the central position.
Die Betätigung des Sperrbolzens erfolgt in umgekehrter Funktionsweise wie beim derzeitigen Lenkschloßsystem: Durch Drehung des Zylinderkerns mittels Schlüssel in Öffnungsrichtung wird der Sperrbolzen formschlüssig in den Käfig gefahren und hält diesen in Mittelstellung. Diese Stellung wird beigehalten, bis durch Rückdrehen und Abziehen des Schlüssels eine federnde Rückstellung des Sperrbolzens erfolgt. Durch Ausweichen des Käfigs um je 3° aus der Mittellage wird die Lenkung blockiert. The locking pin is operated in the opposite way to the current steering lock system: By turning the cylinder core with a key in the opening direction, the locking pin is positively inserted into the cage and holds it in the central position. This position is maintained until the locking bolt is resiliently reset by turning back and removing the key. The steering is blocked by deflecting the cage by 3 ° from the central position.
