Description
Lenkvorrichtungen für Kraftfahrzeuge mit Allradlenkung, bei denen das Einschalten der Hinterradlenkung durch eine Wechselkupplung erfolgt, sind bekannt.Steering devices for motor vehicles with all-wheel steering, in which the rear wheel steering is switched on by means of an interchangeable clutch, are known.
Die bekannten Hinterradlenkungen erscheinen jedoch für schwere Kraftfahrzeuge mit schwerer Anhängerlast nicht zuverlässig genug.However, the known rear wheel steering appear for heavy motor vehicles not reliable enough with a heavy trailer load.
Die neue Erfindung erfüllt alle Ansprüche, die bei schweren Kraftfahrzeugen an eine zusätzliche Hinterradlenkung gestellt werden müssen.The new invention meets all the requirements for heavy motor vehicles must be placed on an additional rear-wheel steering.
Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise und schematisch dargestellt.In the drawing, the subject matter of the invention is, for example, and shown schematically.
Fig. A zeigt die Gesamtanordnung der Hinterradlenkung und Hinterradverriegelung; Fig. B zeigt die Segmentkupplung im Schnitt von hinten gesehen, und Fig. C, D und E zeigen Einzelheiten der Erfindung.Fig. A shows the overall arrangement of the rear wheel steering and rear wheel locking; Fig. B shows the segment coupling seen in section from the rear, and Fig. C, D and E show details of the invention.
Die Steuerkraft für die Hinterradlenkung wird über die Steuersäule und das normale Lenkgetriebe auf den Hebel a und von dort über die Schubstangen b und c, den Hebel d, über die Welle e auf das Segment k übertragen, das mit der Welle e starr verbunden ist.The control force for the rear-wheel steering is transmitted via the control column and the normal steering gear to lever a and from there via push rods b and c, lever d, via shaft e to segment k , which is rigidly connected to shaft e.
Das Schalten der Hinterradlenkung erfolgt vom Fahrersitz aus mit dem Hebel m, der vorn unter dem Fahrersitz angeordnet ist. Die Klaue am Hebel m (Fig. D) greift über eine Verschiebefedern und spannt diese in der gewünschten Schaltrichtung. Das eine Ende der Verschiebefeder n ist am Rahmen o befestigt, während das andere Ende beweglich zwischen den beiden Ringen g liegt. Die beiden Ringe g und der Hebel i sitzen fest auf dem Rohr f. Das Segment k dreht sich mit der Welle e bei jedem Lenkradausschlag für die Vorderräder, da die Steuerkraft von der Schubstange b der Vorderradlenkung über eine Gelenkkupplung auf die Schubstange c übertragen wird.The rear-wheel steering is switched from the driver's seat with the lever m, which is located at the front under the driver's seat. The claw on the lever m (Fig. D) engages via a sliding spring and tensions it in the desired switching direction. One end of the sliding spring n is attached to the frame o, while the other end is moveable between the two rings g. The two rings g and the lever i sit firmly on the tube f. The segment k rotates with the shaft e with every steering wheel deflection for the front wheels, since the control force is transmitted from the push rod b of the front wheel steering to the push rod c via a joint coupling.
Durch den Druck des Hebels m wird über die gespannte Verschiebefeder n das Rohr f mit dem Hebel i in die gewünschte Stellung, Hinterradlenkung oder Verriegelung, verschoben. Beim Umschalten wird vom Fahrer der Hebel yn abwärts gedrückt oder hochgezogen und in einem Raster p festgestellt; dabei wird die Verschiebefeder n vorgespannt, welche in der Mittelstellung der Vorderräder selbsttätig die Verschiebung des Hebels i mit den daran befindlichen Nocken q in den gegenüberliegenden Segmentausschnitt vornimmt.As a result of the pressure of the lever m, the tube f is moved with the lever i into the desired position, rear wheel steering or locking, via the tensioned displacement spring n. When switching, the driver pushes the lever yn down or pulls it up and sets it in a grid p; in the process, the displacement spring n is pretensioned, which in the middle position of the front wheels automatically moves the lever i with the cams q located on it in the opposite segment cutout.
Der Fahrer braucht also nur einen Augenblick eine Hand vom Lenkrad zu nehmen und kann in jeder beliebigen Stellung der Räder, zu jedem Zeitpunkt und jeder Geschwindigkeit die Schaltung vornehmen.The driver only needs one hand off the steering wheel for a moment to take and can in any position of the wheels, at any time and make the shift at any speed.
Der Abstand der beiden Segmente h und k ist so gering gehalten, daß die Hinterräder nie ohne Lenkung bzw. Verriegelung sind. Der Hebelnocken q verläßt nämlich den Segmentausschnitt des auszuschaltenden Segmentes erst dann, wenn der Nocken q bereits ganz in dem gegenüberliegenden Segment eingeschoben ist.The distance between the two segments h and k is kept so small that the rear wheels are never without steering or locking. The lever cam q leaves the segment cutout of the segment to be disengaged only when the cam q has already been fully inserted into the opposite segment.
Wird nach Fig: C der Hebel i nach rechts geschoben, so greift der Nocken q in den Segmentausschnitt vom Segment h und die Hinterradlenkung ist unwirksam, d. h. die Hinterräder sind ihrer Mittelstellung verriegelt.If the lever i is pushed to the right according to Fig: C, the lever engages Cam q in the segment section of segment h and the rear wheel steering is ineffective, d. H. the rear wheels are locked in their middle position.
Die Welle e mit dem Segment k kann sich dabei frei drehen, dagegen wird der Hebel i mit der Schubstange L in dem Segment h festgehalten. Das Segment h ist fest mit dem Fahrgestellrahmen o verbunden.The shaft e with the segment k can rotate freely, while the lever i with the push rod L is held in the segment h . The segment h is firmly connected to the chassis frame o.
Wird der Hebel i nach links geschoben (Fig. E), so greift der Nocken q in den Ausschnitt vom Segment k und betätigt damit die Schubstange l am unteren Ende des Hebels i. Die Hinterradlenkung ist damit eingeschaltet und sofort wirksam.If the lever i is pushed to the left (Fig. E), the cam q engages in the section of the segment k and thus actuates the push rod l at the lower end of the lever i. The rear wheel steering is switched on and takes effect immediately.
