Abstract

In a device for the steering of wheel sets of a vehicle, particularly of a crane vehicle comprising at least two strut girders (2') arranged symmetrically in pairs and pivotable in opposite directions and to which are fixed the wheel sets, one after the other, so as to pivot about a vertical rotation axis (4'), the control levers (6') of each wheel set being connected by an adjustable steering linkage for a plurality of different positions of the strut girders. A simplified readjustment of the wheel sets according to the different predetermined positions of the strut girders is obtained by connecting the articulation points of the steering linkage corresponding to the wheel sets to an intermediary lever (10') pivotable about the vertical rotation axis (4') but not connected to the latter. The intermediary lever (10') may be connected to the control lever (6') in the predetermined positions of the strut girders. In an embodiment of the invention, a lock (25) connected to the control lever (6') engages corresponding hollows (7'-9') of the intermediary lever (10').

Lenkeinrichtung für hintereinandergeschaltete Rad¬ sätze eines Fahrwerks, insbesondere eines Fahrzeug- kransSteering device for series-connected wheel sets of a chassis, in particular a mobile crane
Die Erfindung bezieht, sich auf eine gemeinsame Lenk- einrichtung für die Radsätze eines Fahrwerks, insbe¬ sondere eines Fahrwerks für einen Fahrzeugkran, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a common steering device for the wheel sets of a trolley, in particular a trolley for a mobile crane, with the features of the preamble of claim 1.
Bei Fahrgestellen, die zur Fahrzeuglängsachse paar¬ weise symmetrisch ausschwenkbare,mit einer Anzahl von Radsätzen versehene Stützträger aufweisen, ist es erforderlich, daß für jede bestimmte Stützträger- Stellung sämtliche Radsätze so eingestellt werden, daß die Radachsen - für die Geradeausfahrt des Fahrzeugs - zueinander parallel verlaufen. Um in der neuen Stellung die über ihre Lenkhebel mit dem gemeinsamen Lenkgestänge verbundenen Rad¬ sätze weiterhin lenken zu können, ist ein Ein¬ stellen der Hebel auf die neue Fahrstellung er¬ forderlich. Dazu ist der Hebel in der Regel mit mehreren, den einzelnen Stellungen zugeordneten Anlenkpunkten versehen, in welche die zugeordne¬ ten Anlenkpunkte des Lenkgestänges umgesteckt werden müssen. Solche Umsteckarbeiten sind, insbe¬ sondere bei schwerem Gerät, umständlich, zeit- aufwendig und unfallträchtig.In the case of chassis which have support beams which can be pivoted symmetrically in relation to the longitudinal axis of the vehicle and are provided with a number of wheel sets, it is necessary for all wheel sets to be set for each specific support support position so that the wheel axes - for the straight-ahead travel of the vehicle - are parallel to one another run. In order to be able to steer the wheel sets connected to the common steering linkage via their steering levers in the new position, it is necessary to adjust the levers to the new driving position. For this purpose, the lever is generally provided with a plurality of articulation points assigned to the individual positions, into which the articulated articulation points of the steering linkage must be repositioned. Such transfer work is cumbersome, time-consuming and prone to accidents, especially in the case of heavy equipment.

Einstellvorgangs Abhilfs zu schaffen. Die Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Anspruchs 1.To remedy the adjustment process. The solution to this problem consists in the characterizing features of claim 1.
Die Erfindung bringt in erster Linie den Vorteil, daß Umsteck-, Umbauarbeiten oder ein Austausch von zum Lenkgestänge gehörenden Teile entfallen, die Sicherheit für die Bedienungsmannschaft bei der Umstellung der Radsätze auf die jeweilige' Ver¬ stellung der Stützträger erheblich verbessert und eine Selbsttätigkeit des Einstellvorgangs ermöglicht wird.The primary advantage of the invention is that there is no need for repositioning, conversion work or an exchange of parts belonging to the steering linkage, the safety for the operating team when converting the wheel sets to the respective adjustment of the support beams is considerably improved, and the adjustment process becomes independent is made possible.
Vorteilhafte Ausgestaltungen der Lenkeinrichtung nach der Erfindung sind Gegenstand der Ansprüche 2 bis 6.Advantageous embodiments of the steering device according to the invention are the subject of claims 2 to 6.
In der Zeichnung sind mehrere Ausführungsbeispiele des Lenkgestänges nach der Erfindung schematisch dargestellt und anhand der nachfolgenden Beschrei¬ bung näher erläutert.

Am Untergestell 1 eines Fahrzeugkrans sind an dessen bezogen auf die Fahrtrichtung hinterem Ende zwei Stützträger 2 jeweils ineinem Lager 3 angelenkt und (paarweise) symmetrisch zueinander angeordnet. In Fig. 1 ist der Einfachheit halber jeweils nur einer der beiden Stützträger 2 dargestellt, wobei a die Stellung der Stützträger 2 in Fahrtrichtung ausgerichtet, b eine um 10 von der Fahrzeuglängsachse gemessen nach außen verschwenkte Stellung und c eine um etwa 45 nach außen verschwenkte Stellung zeigt. Der Spreizwinkel der beiden symmetrischen Stütz¬ träger 2 ist somit jeweils doppelt so groß.On the underframe 1 of a mobile crane, at its rear end in relation to the direction of travel, two support beams 2 are each articulated in a bearing 3 and arranged (in pairs) symmetrically to one another. 1, for the sake of simplicity, only one of the two support beams 2 is shown, with a the position of the support beams 2 oriented in the direction of travel, b a position pivoted outwards by 10 from the longitudinal axis of the vehicle and c a position pivoted outwards by approximately 45 shows. The spread angle of the two symmetrical support beams 2 is thus twice as large.
Jeder der beiden Stützträger 2 ist mit jeweils um eine senkrechte Drehachse 4 verschwenkbaren Rad- sätzen 5 versehen, wobei die Lenkhebel 6 so ange¬ ordnet sind, daß sie in der Stellung a nach hinten weisend ebenso wie ihre zugeordneten Fahrgestelle 5 miteinander fluchten. An jedem Fahrgestell ist ein um die Drehachse 4 schwenkbarer, mit Positionsele- menten 7, 8 und 9 versehener scheibenartiger Zwi¬ schenhebel 10 lose angeordnet, der außerdem einen Anlenkpunkt 11 für das Lenkgestänge aufweist. Da¬ bei sind die Anlenkpunktebenachbarter Zwischenhebel 1 jeweils über eine Stange 12 miteinander verbunden, während der Anlenkpunkt des an das Untergestell 1 anschließenden Radsatzes 5 an einen hydraulischen Lenkzylinder 13 angeschlossen ist, welcher in einer senkrechten Drehachse 15 am Untergestell 1 "" 4 -Each of the two support brackets 2 is provided with wheel sets 5 which can each be pivoted about a vertical axis of rotation 4, the steering levers 6 being arranged in such a way that, in position a, they point backwards as do their associated chassis 5. A disc-like intermediate lever 10, which can be pivoted about the axis of rotation 4 and is provided with position elements 7, 8 and 9, is loosely arranged on each undercarriage and also has a pivot point 11 for the steering linkage. The articulation points adjacent intermediate lever 1 are each connected to one another via a rod 12, while the articulation point of the wheel set 5 adjoining the underframe 1 is connected to a hydraulic steering cylinder 13 which is arranged on the underframe 1 in a vertical axis of rotation 15 "" 4 -

In der Stellung a sind sämtliche drei Lenkhebel 6 mit den Positionselementen 7 der Zwischenhebel 10 verbunden, wozu sie entsprechende Gegenelemente aufweisen. In der Stellung b wird eine entsprechende Verbindung zwischen den Hebeln 6 und den Positions¬ elementen 8 der Zwischenhebel 10 hergestellt, nach¬ dem die Radsätze 5 vorher in die dazu passende Stellung gedreht worden sind. Bei der Stellung c sind in gleicher Weise die Hebel 6 den Positions¬ elementen 9 der Zwischenhebel 10 zugeordnet. Die Kolbenstange 14 des Lenkzylinders 13, die einen Teil des Lenkgestänges bildet, ist bei den ausge¬ schwenkten Stellungen der Stützträger 2 entsprechend weiter ausgefahren.In position a, all three steering levers 6 are connected to the position elements 7 of the intermediate lever 10, for which purpose they have corresponding counter elements. In position b, a corresponding connection is made between the levers 6 and the position elements 8 of the intermediate lever 10, after the wheel sets 5 have previously been rotated into the appropriate position. In position c the levers 6 are assigned to the position elements 9 of the intermediate lever 10 in the same way. The piston rod 14 of the steering cylinder 13, which forms part of the steering linkage, is correspondingly extended further in the pivoted-out positions of the support bracket 2.
In Fig. 1 sind in den Stellungen a bis c die Rad¬ sätze jeweils nur in der Geradeausfahrtstellung ge¬ zeigt, wobei ihre Radachsen 16 zueinander parallel verlaufen. Zum Lenken der Radsätze 5 wird der Zy- linder 13 je nach gewünschter Lenkrichtung aus- bzw. eingefahren.1, the wheel sets are shown in the positions a to c only in the straight-ahead driving position, their wheel axes 16 running parallel to one another. To steer the wheel sets 5, the cylinder 13 is extended or retracted depending on the desired steering direction.
Bei der Ausführungsform nach Fig. 2 weist jeder Radsatz 5' vier gleichachsige Räder auf, die beid- seitig ihrer senkrechten Drehachse 4' angeordnet sind. An den in gleicher Weise wie beim vorherge¬ henden Ausführungsbeispiel um die Drehachsen 4' schwenkbaren Zwischenhebeln 10' sind der Fahrzeug¬ längsachse 17 zugewandt und symmetrisch weitere Hebelscheiben 18, 19 und 20 befestigt, an denen neben dem Lenkgestänge jeweils noch ein Lenkhilfs¬ zylinder 21 angelenkt ist. Die am Untergestell 1' schwenkbar befestigten Lenkzylinder 13' sind mit ihren Kolbenstangen 14' j'eweils an der mittleren - 5 ~In the embodiment according to FIG. 2, each wheel set 5 'has four coaxial wheels, which are arranged on both sides of their vertical axis of rotation 4'. On the intermediate levers 10 ', which can be pivoted about the axes of rotation 4' in the same way as in the previous exemplary embodiment, the longitudinal axis 17 of the vehicle faces and symmetrically further lever plates 18, 19 and 20 are fastened, to which, in addition to the steering linkage, there is also a steering auxiliary cylinder 21 is articulated.

Hebelscheibe 19 angelenkt, welche Anlenkpunkte 22, 23 für die zu den Hebelscheiben 18 und 20 führenden Stangen 12' aufweist . Die Hebelscheiben sind hin¬ sichtlich ihrer Anlenkpunkte so gestaltet, daß ein kinematisch günstiges Lenkverhalten erzielt wird. Die LenkhilfsZylinder 21 , die zu dem gleichen Zweck zusätzlich verwendet werden, sind mit ihrem anderen Ende jeweils an dem in Fig. 2 nicht dargestellten Stützträger 2' angelenkt.Articulated lever disk 19, which has articulation points 22, 23 for the rods 12 'leading to the lever disks 18 and 20. With regard to their articulation points, the lever disks are designed in such a way that a kinematically favorable steering behavior is achieved. The steering auxiliary cylinders 21, which are additionally used for the same purpose, are articulated at their other ends to the support bracket 2 ', not shown in FIG. 2.
Die Lenkhebel 61 sind bei diesem Ausführungsbei- spiel, wie es am besten aus Fig. 3 hervorgeht, als die Zwischenhebel 10' oben und unten umgreifende Doppelhebel ausgebildet. Der Hebel 6' ist mit dem Drehgestell des zugeordneten Radsatzes fest ver- bunden, welches an einem an den Stützrahmen 2' an¬ geflanschten Achsstummel gelagert ist, was durch die Flanschverbindung 24 erkennbar ist. Der Zwi¬ schenhebel 10' weist als Positionselemente drei Einkerbungen 7', 81 und 91 auf, welche sich be- zogen auf die Radsatzdrehachse 4' radial nach außen erweitern. Ein nach unten abgewinkelter Riegel 25 ist, wie es Fig. 4 zeigt, am unteren Arm des Lenk¬ hebels 6' in einem Lagerauge 26 so gelagert, daß er nach außen und unten wegklappen kann und dadurch die Einrastung-Position in einer der Ausnehmungen 7' bis 9' freigibt. Dazu wird ein Absteckbolzen 27, der ihn in der Einrastposition hält, herausgezogen. Das Einrasten und Lösen des Riegels 25 kann selbst¬ tätig erfolgen. Bei der gelösten Position dient die Unterseite des unteren Arms des Lenkhebels 61 gleichzeitig als Anschlag gegen ein weiteres Herun¬ terfallen des Riegels. - 6 -In this exemplary embodiment, as can best be seen in FIG. 3, the steering levers 6 1 are designed as double levers encompassing the intermediate levers 10 'at the top and bottom. The lever 6 'is firmly connected to the bogie of the associated wheel set, which is mounted on an axle stub flanged to the support frame 2', which can be recognized by the flange connection 24. The intermediate lever 10 'has three notches 7', 8 1 and 9 1 as position elements, which expand radially outwards in relation to the wheel set axis of rotation 4 '. A downwardly angled latch 25, as shown in FIG. 4, is mounted on the lower arm of the steering lever 6 'in a bearing eye 26 in such a way that it can fold outwards and downwards and thereby the latching position in one of the recesses 7 releases 'to 9'. For this purpose, a locking pin 27, which holds it in the locked position, is pulled out. The latch 25 can be engaged and released automatically. In the released position, the underside of the lower arm of the steering lever 6 1 simultaneously serves as a stop against further falling of the bolt. - 6 -
Im Gegensatz zu den vorhergehenden Ausführungsbei¬ spielen, bei denen die Anlenkpunkte und die Positions¬ elemente etwa auf dem gleichen Radius und der glei¬ chen Seite der Fahrgestell- Drehachse liegen, ist beim Ausführungsbeispiel nach Fig. 5 und 6 der Radius der Positionselemente kleiner als der des Lenkhebels. Außerdem sind beide Teile etwa gegenüberliegend an¬ geordnet. Der Lenkhebel 6" weist dabei dem Anlenk¬ punkt 11" etwa gegenüberliegend einen nach unten weisenden hakenförmigen Vorsprung 28 auf, der in eine langlochartige gebogene Nut 29 des losen^um den Lenkhebel 6' gelagerten Zwischenhebels 30 ein¬ greift. Der Zwischenhebel 6" ist an einem Drehge¬ stell 31 befestigt, welches an einem an dem Stütz- träger 2 angeflanschten Achsstummel 32 um die Dreh¬ achse 4 schwenkbar gelagert ist. Die Einrichtung nach diesem Ausführungsbeispiel ist lediglich für zwei Schwenk-Stellungen des Stützträgers ausgelegt, wobei die Einrastung selbsttätig dadurch erfolgt, daß der Nocken 28 an einen der Endanschläge 33 oder 34, welche die Nut 29 bildet, anschlägt, wo¬ nach ein keilförmiger Riegel 35 durch einen Stell¬ motor 36 den Nocken 28 in seiner Position fest¬ keilt. Der Keil 35 unterteilt in seiner Einrast- position die Nut 29 in zwei gleich große Abschnitte, welche durch den Nocken 28 jeweils vollständig ausgefüllt werden. Der Schwenkwinkel beträgt^bei diesem Ausführungsbeispiel entsprechend der Dar¬ stellung nach Fig. 6 etwa 40 .In contrast to the previous exemplary embodiments, in which the articulation points and the position elements lie approximately on the same radius and on the same side of the chassis axis of rotation, in the exemplary embodiment according to FIGS. 5 and 6 the radius of the position elements is smaller than that of the steering lever. In addition, both parts are arranged approximately opposite one another. The steering lever 6 "has an articulation point 11" approximately opposite a downward-facing hook-shaped projection 28 which engages in a slot-like curved groove 29 of the loose intermediate lever 30 mounted around the steering lever 6 '. The intermediate lever 6 "is fastened to a rotary frame 31, which is pivotably mounted on an axle stub 32 flanged to the support bracket 2 about the rotary axis 4. The device according to this exemplary embodiment is designed only for two pivot positions of the support bracket , the engagement taking place automatically in that the cam 28 strikes one of the end stops 33 or 34, which forms the groove 29, after which a wedge-shaped latch 35 wedges the cam 28 in its position by an actuator 36 . the wedge 35 is divided in its latching position, the groove 29 into two equal portions which are completely filled by the cam 28, respectively. the pivot angle is ^ in this embodiment according to the Dar¬ position of FIG. 6 approximately 40.
Nach der Erfindung ist es auch möglich, an Stelle des Zwischenhebels den Lenkhebel mit den den Stütz¬ träger-Stellungen zugeordneten Positionselementen zu versehen. Diese Positionselemente können sich außerdem auch auf beide Hebel verteilen. Damit ist die Lenkeinrichtung den Forderungen leicht anzupassen. - 7 -According to the invention, it is also possible, instead of the intermediate lever, to provide the steering lever with the position elements assigned to the support bracket positions. These position elements can also be distributed over both levers. The steering device can thus be easily adapted to the requirements. - 7 -
