Description
Abschaltvorrichtung für den Vorderradantrieb eines allradangetriebenen Schleppers für land- und forstwirtschaftliche Betriebe Die an einen Ackerschlepper gestellten Anforderungen sind sehr hoch. Er soll als Arbeitsmaschine auf dem Acker vielseitig verwendbar und auch als Zugmaschine auf der Straße wendig und zugkräftig sein. Die Schlepper werden daher in neuerer Zeit mit Vierradantrieb ausgerüstet. Im Gelände hat dieser den Vorteil einer wesentlich besseren Steuerungsmöglichkeit und damit Spurhaltung sowie einer größeren Zugkraft und auf der Straße den einer erhöhten Bremswirkung.Disconnection device for the front-wheel drive of a four-wheel drive Tractors for agricultural and forestry operations The to an agricultural tractor The requirements set are very high. It should be used as a work machine in the field Versatile and also agile and powerful as a tractor on the road be. The tractors have therefore recently been equipped with four-wheel drive. In the field, this has the advantage of a much better control option and thus lane keeping as well as a greater tractive force and on the road the one increased braking effect.
Es ist bekannt, die Antriebsorgane der Vorderräder in einem besonderen anschraubbaren oder austauschbaren Gehäuse unterzubringen. Bei einer bevorzugten Ausführungsform erfolgt der Abtrieb des Vorderradantriebes von einer zwischen Schaltgetriebe und Hinterachse liegenden Zwischenwelle, wobei die Antriebsorgane sowohl rechts als auch links von der Schlepperlängsachse angeordnet sein können und die abtreibenden Zahnräder in einem vor der Stirnseite der Zwischenwellenlagerung bzw. der Getriebebremstrommel angeschraubten Gehäuse angeordnet sind. Es kann der Abtrieb des Vorderradantriebes aber auch von dem Hinterachsdifferential aus erfolgen.It is known that the drive organs of the front wheels in a particular To accommodate screw-on or replaceable housing. With a preferred Embodiment, the output of the front wheel drive takes place between a gearbox and rear axle lying intermediate shaft, the drive elements both on the right as well as to the left of the tractor's longitudinal axis can be arranged and the aborting Gears in one in front of the end face of the intermediate shaft bearing or the gear brake drum screwed housing are arranged. It can be the output of the front-wheel drive but also take place from the rear axle differential.
Da der Vorderradantrieb bei den Arbeiten eines Schleppers nicht immer benötigt wird, ist er meist abschaltbar. Hierzu wird eine Klauenkupplung verwendet, die mittels eines Hebels entgegen der Spannung einer Feder ausgeschaltet werden kann. Oft ,ist diese Kupplung auch so ausgebildet, d!aß sie reit ihrer Feder die Kräfteverteilung auf die Vorder-und Hinterräder regelt. Gemäß der Erfindung ist für den Vorderradantrieb eine indirekte, d.h. nicht unmittelbar durch Betätigung eines Bedienungsgliedes in Wirkung tretende Abschaltung vorgesehen. Diese Abschaltung erfolgt durch eine beim Einschalten vorgespannte Feder, deren Spannung beim Abschalten zunächst nur freigegeben wird und erst abschaltet, wenn die Kupplungsteile sich durch den Betrieb gelockert haben. Diese Art der Abschaltung erleichtert sie und schont die Getriebe, da die Kupplungsteile erst dann ausschalten, wenn keine Überbeanspruchung mehr vorhanden ist.Because the front-wheel drive is not always used when working with a tractor is required, it can usually be switched off. A claw coupling is used for this, which are switched off by means of a lever against the tension of a spring can. Often this coupling is also designed in such a way that it rides its spring Controls the distribution of forces on the front and rear wheels. According to the The invention is indirect for the front-wheel drive, i.e. not directly through Actuation of an operating member in effect disconnection provided. These Shutdown takes place by a spring pretensioned when switching on, the tension of which when switching off is initially only released and only switches off when the coupling parts have loosened through the operation. This type of shutdown makes them easier and protects the transmission, as the clutch parts only switch off when none There is no longer any overuse.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. I eine schematische Darstellung der Antriebsorgane des Schleppers in Draufsicht, Fig. 2 einen Querschnitt durch die Abtriebsstelle des Vorderradantriebes ein der Zwischenwelle, Fig.3 eine Ansicht des Anschlußgehäuses des Antriebes nach Fig. 2 mit der nach den Vorderrädern gehenden Welle, teilweise im Schnitt, Fig. 4 eine Draufsicht auf Fig. 3 in Pfeilrichtung, Fig. 5 einen Schnitt nach der Linie V-V der Fig. 4. Der Grundaufbau des Schleppers entspricht der Blockbauweise, d. h. Motor-, Getriebe- und Hinterachsgehäuse sind zu einem Block zusammengebaut. Der Motor I treibt über das Schaltgetriebe 2 eine Zwischenwelle 3 an, von der der Antrieb der Hinterachse 4 und auch nach den Fig. I bis 5 der Antrieb der Vorderachse 5 abgenommen ist. Von dem Schaltgetriebe gehen noch der Mähantrieb 6, eine Zapfwelle 7 und der Antrieb einer Riemenscheibe 8 ab.An exemplary embodiment of the invention is shown in the drawing. It shows Fig. I a schematic representation of the drive elements of the tractor in plan view, FIG. 2 shows a cross section through the output point of the front-wheel drive one of the intermediate shaft, Figure 3 is a view of the connector housing of the drive Fig. 2 with the shaft going to the front wheels, partially in section, Fig. 4 shows a plan view of FIG. 3 in the direction of the arrow, FIG. 5 shows a section along the line V-V of Fig. 4. The basic structure of the tractor corresponds to the block construction, i. H. The engine, transmission and rear axle housings are assembled into one block. Of the Motor I drives an intermediate shaft 3 via the gearbox 2, from which the drive the rear axle 4 and also according to FIGS. I to 5, the drive of the front axle 5 removed is. The mowing drive 6, a power take-off shaft 7 and the mowing drive go from the gearbox Drive a pulley 8 from.
Nach Fig. I ist hinter der auf der Zwischenwelle 3 sitzenden Getriebebremse 9 die Kupplung Io für den durch Kegelräder II erfolgenden Vorderradantrieb angeordnet. Die die Kegelräder II mit den auf der Vorderachse 5 sitzenden Kegelrädern I2 verbindende Welle I3 ist eine Gelenkwelle und, von den Kegelrädern II schräg nach unten nach den Rädern I2 geführt.According to Fig. I is behind the 3 seated on the intermediate shaft gear brake 9 the clutch Io is arranged for the front-wheel drive effected by bevel gears II. The one connecting the bevel gears II with the bevel gears I2 sitting on the front axle 5 Shaft I3 is a cardan shaft and, from the bevel gears II, obliquely downwards the wheels I2 out.
Die Vorderräder I4 und Hinterräder I5 haben ungleiche Größe. Das hat den Vorteil, daß der große Lenkausschlag bei der genormten Spur beibehalten werden kann.The front wheels I4 and rear wheels I5 are of different sizes. That has the advantage that the large steering angle can be retained in the standardized track can.
In den Fig. 2 und 3 sind die Getriebebremse 9, die Kupplung Io und die Kegelräder II in ihren Gehäusen I6, I7 vergrößert dargestellt. Das mit dem Getriebeblock I8 zusammengebaute Gehäuse I6 der Bremse 9 ist so ausgebildet, daß das Abtriebsgehäuse I7 des Vorderradantriebes auf der betreffenden Stirnseite der Zwischenwelle 3 leicht an dieses angeschraubt werden kann. Im Ausführungsbeispiel ist die Welle I3 aus dem Gehäuse I7 schräg herausgeführt. Das ergibt einen zweckmäßigen und billigen Antrieb und günstige Bodenfreiheit. Die Ausbildung des Gehäuses I7 kann aber auch derart sein, daß der Abtrieb zunächst senkrecht nach unten erfolgt und dann zum Anschluß an die dabei waagerecht liegende Gelenkwelle im Winkel geführt ist. Nach Fig. I ist der Vorderradantrieb links von der Motorachse angeordnet. Er kann aber ebensogut rechts von dieser liegen, wobei dann auch die Getriebebremse 9 auf der anderen Seite liegen kann und das Gehäuse I7 spiegelbildlich ausgeführt wird.In Figs. 2 and 3, the transmission brake 9, the clutch Io and the bevel gears II shown enlarged in their housings I6, I7. The one with the gear block I8 assembled housing I6 of the brake 9 is designed so that the output housing I7 of the front wheel drive on the relevant end face of the intermediate shaft 3 slightly can be screwed to this. In the exemplary embodiment, the shaft I3 is off the housing I7 led out at an angle. That makes a useful and cheap one Drive and favorable ground clearance. The design of the housing I7 can also be such that the output is first perpendicular to the bottom and then to Connection to the horizontal cardan shaft is guided at an angle. To Fig. I the front wheel drive is arranged to the left of the engine axis. But he can just as well to the right of this, with the transmission brake 9 on the can be on the other side and the housing I7 is designed as a mirror image.
Mit Ader Kupplung Io wird der Vorderradantrieb zu- und abgeschaltet. Die Abschaltung erfolgt indirekt. Hierbei spannt der Bedienungshebel I9 (Fig. 4 und 5) beim Einschalten eine Drehfeder 2o. Wird nun beim Ausschalten der Hebel I9 aus seiner Raste 2I gehoben, dann legt er sich zunächst nur mit seinem Rücken an den Bolzen 22, ohne daß die Abschaltung selbst erfolgt. Letztere tritt erst dann ein, wenn im weiteren Betrieb des Schleppers sich die Kupplungsteile so weit gelockert haben, daß die Spannung der Feder 2o den mit dem Bedienungshebel I9 über die Kurbel 23 verbundenen Exzenter 24 drehen und damit die Kupplungsmuffe ausrücken kann. Der Hebel I9 geht dabei mit der Kurbel 23 in die gestrichelt gezeichnete Lage.The front wheel drive is switched on and off with wire clutch Io. The shutdown takes place indirectly. The operating lever I9 (Fig. 4 and 5) a torsion spring 2o when switched on. If the lever I9 lifted out of its notch 2I, then it initially only lies down with its back the bolt 22 without the shutdown itself taking place. The latter only occurs then on, if the coupling parts are loosened so much during further operation of the tractor have that the tension of the spring 2o with the control lever I9 over the crank 23 connected eccentric 24 and thus the coupling sleeve can disengage. Of the Lever I9 goes with the crank 23 in the position shown in dashed lines.
