Description
Die Erfindung betrifft eine Lenkvorrichtung vornehmlich für Vierradfahrzeuge.The invention relates to a steering device primarily for four-wheel vehicles.
Es ist bei Lenkvorrichtungen für Kraftfahrzeuge bekannt, die vier Räder von einer gemeinsamen Steuersäule aus zum Einschlag zu bringen. Es ist ferner in Verbindung mit einer derartigen Vierradlenkung eine Einstellbarkeit des Lenkgestänges in der Weise vorgeschlagen worden; daß Vorder- und Hinterräder des Fahrzeuges in die verschiedensten Stellungen zueinander gebracht werden können. Man verfolgte mit dieser Anordnung den Zweck, das Fahrzeug wendiger zu machen, eine Drehung um eine senkrechte Mittelachse zu ermöglichen oder auch das Fahrzeug parallel zu seiner Längsachse zu versetzen.It is known in steering devices for motor vehicles, the four To bring the wheels to the turning from a common steering column. It is further in connection with such a four-wheel steering, an adjustability of the steering linkage has been suggested in the manner; that the front and rear wheels of the vehicle in the most diverse positions can be brought to one another. One pursued with this arrangement the purpose of making the vehicle more manoeuvrable is one turn around to allow a vertical central axis or the vehicle parallel to his To offset the longitudinal axis.
Der Erfindung liegt demgegenüber der Gedanke zugrunde, z. B. bei Ackerschleppern, den auf das Fahrzeug einwirkenden äußeren Querkräften durch entgegengesetzte Radeinstellung entgegenzuwirken, um die vorgesehene Fahrtrichtung unbedingt einzuhalten. Um dieses Ziel zu erreichen, sind gemäß der Erfindung Mittel vorgesehen, die die wahlweise Verstellung, z. B. Voreinstellung, der Räder unabhängig von der Betätigung der Lenkvorrichtung ermöglichen. In der praktischen Ausführung kann ein derartiges Mittel ein Scherenhebel sein, der in seinem Scharnier drehbar gelagert ist und an dessen einstellbaren Schenkelenden das an dieser Stelle unterbrochene Lenkgestänge angreift. Zweckmäßig fällt das Scherenhebelscharnier mit dem Drehpunkt des Steuersäulensegments zusammen. Verstellt man den einen oder anderen Schenkel des Scherenhebels, so wird dadurch ein Einschlag der betreffenden Fahrzeugräder erreicht, ohne daß die Steuersäule betätigt worden ist.The invention is based on the idea, for. B. with agricultural tractors, the external transverse forces acting on the vehicle due to the opposite wheel setting to counteract in order to strictly adhere to the intended direction of travel. To this To achieve the goal, means are provided according to the invention, which the optional Adjustment, e.g. B. Presetting, the wheels regardless of the operation of the steering device enable. In practice, such a means can be a scissor lever be, which is rotatably mounted in its hinge and at its adjustable leg ends the steering linkage, which is interrupted at this point, engages. The scissor lever hinge expediently falls coincides with the pivot point of the control column segment. If you adjust the one or other leg of the scissor lever, this is an impact of the relevant Vehicle wheels reached without the control column has been operated.
Wenn z. B: ein Ackerschlepper bei seiner Fahrt in der Furche unter Einwirkung äußerer Kräfte die Neigung zeigt, sich in unerwünschter Weise aus der Fahrtrichtung zu bewegen, so kann das in Anwendung der Erfindung dadurch verhindert werden, daß den Fahrzeugrädern eine entsprechende Voreinstellung gegeben wird, die während der Fahrt derartigen Kräften entgegenwirkt.If z. B: an agricultural tractor driving under the furrow The action of external forces shows the tendency to emerge from the in an undesirable manner To move the direction of travel, this can be prevented in application of the invention be that the vehicle wheels are given a corresponding preset that counteracts such forces while driving.
In gleicher Weise kann verfahren werden, wenn, ein Fahrzeug bei seitlicher Schräglage am Hang unter dem Einfluß seines Eigengewichtes bestrebt ist, aus der Fahrtrichtung abzuweichen.The same procedure can be used when a vehicle is at the side Tilting on the slope under the influence of its own weight strives from the To deviate in the direction of travel.
In der Zeichnung ist die Erfindung veranschaulicht. Es zeigt Abb. i in der Draufsicht das Lenkschema eines vierradgelenkten Fahrzeuges in bekannter Ausführung, Abb. 2 und 3 dasselbe Schema mit den Mitteln gemäß der Erfindung.The invention is illustrated in the drawing. It shows fig. i in the plan view the steering scheme of a four-wheel-steered vehicle in known Embodiment, Fig. 2 and 3 the same scheme with the means according to the invention.
In den Abbildungen sind die Radpaare mit i und 2 bezeichnet, 3 sind die bekannten Spurstangen, die die beiden Räder eines Radpaares bewegungsabhängig miteinander verbinden. An den Winkelarmen ¢ sind die Schubstangen 5 und 6 angelenkt, die über den Schwenkhebel 7 mit der Steuersäule 8 in Verbindung stehen.In the figures, the pairs of wheels are denoted by i and 2, 3 are the well-known tie rods that move the two wheels of a pair of wheels connect with each other. The push rods 5 and 6 are hinged to the angle arms ¢, which are connected to the control column 8 via the pivot lever 7.
Die Anordnung ist, wie aus Abb. i ersichtlich, so getroffen, daß bei Betätigung der Steuersäule 8 die Radpaare i und 2 im entgegengesetzten Sinne eingeschlagen werden.The arrangement is, as can be seen from Fig. I, such that at Actuation of the control column 8, the pairs of wheels i and 2 hit in the opposite direction will.
Gemäß der Erfindung ist der Schwenkhebel 7 als Scherenhebel mit den beiden Schenkeln 9 und io ausgebildet. Diese beiden Scherenschenkel 9 und 1o . sind unabhängig von der Betätigung der Steuersäule 8 gegeneinander verstellbar. Dadurch ist es möglich, den Rädern 2 unabhängig von der Steuersäulenbetätigung beispielsweise die Stellung b zu geben. Das Fahrzeug wird dann die Neigung haben, aus der Fahrtrichtung nach rechts abzuweichen und die Wirkung einer entgegengesetzt gerichteten Kraft somit aufzuheben.According to the invention, the pivot lever 7 is a scissor lever with the two legs 9 and io formed. These two scissor legs 9 and 1o. are independently of the actuation of the control column 8 against each other adjustable. Through this it is possible to control the wheels 2 independently of the control column actuation, for example to give the position b. The vehicle will then tilt out of the direction of travel deviating to the right and the effect of an oppositely directed force thus repeal.
Abb. 3 veranschaulicht im wesentlichen die gleiche Ausführung wie Abb. 2. Der Scherenhebel ist vierschenkelig ausgebildet, und die freien Schenkelenden i 1, 12 können durch eine Verstellvorrichtung, z. B. Spindel 13 und Handrad 14, gegeneinander verstellt werden. Die Auswirkung, die sich aus einer derartigen Verstellung des Scherenhebels auf die Räder i und 2 ergibt, ist im wesentlichen die gleiche wie bei derAnordnung gemäß Abb. 2.Fig. 3 illustrates essentially the same design as Fig. 2. The scissor lever is four-legged, and the free leg ends i 1, 12 can be adjusted by an adjusting device, e.g. B. spindle 13 and handwheel 14, can be adjusted against each other. The effect of such an adjustment of the scissor lever on wheels i and 2 is essentially the same as with the arrangement according to Fig. 2.
