Description
Lastwagen mit Allradantrieb Die vorliegende Erfindung bezieht sich auf einen Lastwagen mit Allradantrieb. Erfindungsgemäss ist jedes Rad mit einem Ölmotor versehen, dessen Dreh zahl von der Ölmenge abhängt, wobei zwischen dem Ölmotor und dem Rad ein Planetengetriebe mit zwei Betriebsstellungen vorhanden ist.
Auf beiliegender Zeichnung ist ein Ausführungs beispiel des Erfindungsgegenstandes dargestellt.
Die dargestellte Anordnung zeigt ein Rad 1 des Strassenfahrzeuges. Dieses weist eine Felge 2 auf, welche von einer Nabe 3 getragen ist. Im Rad 1 ist ein Ölmotor 4, z. B. ein mit Öl betriebener Drehkolbenmotor vorgesehen, welcher Motor mit seinem Flansch 5 mit einem Zwischenstück 13 ver bunden ist. Dieses Zwischenstück ist direkt mit dem Chassis des Lastwagens verbunden. Die Welle 6 des Motors 4 trägt einen Zahnkranz 7, mit welchem vier am Umfang verteilte Planetenräder 8 kämmen. Ferner ist ein in axialer Richtung verschiebbarer Ring 9 vorgesehen, der eine vordere Stirnverzahnung 10 und eine hintere Stirnverzahnung 11 aufweist.
Dieser Ring 9 steht durch eine Verzahnung 12 mit den Panetenrädern 8 ständig in Eingriff. Die Anord nung ist dabei so getroffen, dass durch die Verschie bung des Ringes 9 wahlweise die Verzahnungen 10 oder 11 in Eingriff kommen. In der im oberen Teil in der Zeichnung dargestellten Stellung kämmt die hintere Stirnverzahnung 11 mit einer entsprechenden Verzahnung 14 des Zwischenstückes 13, so dass die Planetenräder gebremst werden. Wird der unten etwas anders ausgebildet gezeichnete Ring axial in die aus dem unteren Teil der Zeichnung ersicht lichen Stellung verschoben, so kommt die vordere Stirnverzahnung 10 mit einer Verzahnung 15 der Nabe 3 in Eingriff.
Zur Verschiebung des Ringes 9 sind hydraulische Mittel vorgesehen, welche durch Leitungen 16 bzw. 17 in Druckräume 18 bzw. 19 geführt werden. Weitere Leitungen 20, 21 dienen zur Zu- und Ableitung eines Schmiermittels zur Schmierung der Lager der Planetenräder.
In der mittleren Stellung des Ringes 9 steht weder die Verzahnung 10 noch die Stirnverzahnung 11 in Eingriff, so dass die Planetenräder 8 nicht ge bremst werden und demzufolge das Rad 1 nicht angetrieben wird. In der einen Betriebsstellung, bei welcher der Ring 12 nach rechts verschoben ist und die Verzahnung 11 mit der Verzahnung 14 kämmt, wird eine Übersetzung gebildet, welche sich für kleine Fahrtgeschwindigkeit eignet. In der anderen Stellung des Ringes 12, bei welcher die Stirnverzahnung 10 mit der Verzahnung 15 kämmt, wird die überset- zung für die normale Fahrtgeschwindigkeit gebildet.
Der Rückwärtsgang wird durch die Änderung der Drehrichtung des Motors 4 erzielt.
Beim beschriebenen Lastwagen-Allradantrieb ist die Drehzahl des öhnotors nur von der Ölmenge abhängig, wobei durch die Zwischenschaltung dis! beschriebenen Planetengetriebes nebst einer Leer laufstellung zwei abweichende Übersetzungen gebil det werden. Der Öldruck sollte für sämtliche An triebsmotoren gleich bleiben. Bei Drehzahlunterschie den wird ein Regulierorgan in Tätigkeit gesetzt, welches die öhnengen ausgleicht und als Differenzial- sperre wirkt.
Die Ausbildung dieses Regulierorganes bildet nicht Gegenstand der vorliegenden Erfindung.
Four Wheel Drive Truck The present invention relates to a four wheel drive truck. According to the invention, each wheel is provided with an oil motor, the speed of which depends on the amount of oil, a planetary gear with two operating positions being present between the oil motor and the wheel.
In the accompanying drawing, an execution example of the subject invention is shown.
The arrangement shown shows a wheel 1 of the road vehicle. This has a rim 2 which is carried by a hub 3. In the wheel 1 is an oil motor 4, for. B. an oil-operated rotary piston engine is provided, which engine with its flange 5 with an intermediate piece 13 is a related party. This intermediate piece is directly connected to the chassis of the truck. The shaft 6 of the motor 4 carries a ring gear 7 with which four planet gears 8 distributed around the circumference mesh. Furthermore, a ring 9 is provided which is displaceable in the axial direction and has a front spur toothing 10 and a rear spur toothing 11.
This ring 9 is constantly in engagement with the gear wheels 8 through a toothing 12. The arrangement is made in such a way that the gears 10 or 11 come into engagement as a result of the displacement of the ring 9. In the position shown in the upper part of the drawing, the rear spur toothing 11 meshes with a corresponding toothing 14 of the intermediate piece 13, so that the planet gears are braked. If the ring drawn below, slightly differently designed, is axially displaced into the position ersicht from the lower part of the drawing, the front spur toothing 10 comes into engagement with a toothing 15 of the hub 3.
In order to move the ring 9, hydraulic means are provided which are guided through lines 16 and 17 into pressure chambers 18 and 19, respectively. Further lines 20, 21 serve to supply and discharge a lubricant for lubricating the bearings of the planetary gears.
In the middle position of the ring 9, neither the toothing 10 nor the spur toothing 11 is in engagement, so that the planet gears 8 are not braked and consequently the wheel 1 is not driven. In the one operating position in which the ring 12 is shifted to the right and the toothing 11 meshes with the toothing 14, a translation is formed which is suitable for low driving speeds. In the other position of the ring 12, in which the spur toothing 10 meshes with the toothing 15, the gear ratio for normal travel speed is formed.
Reverse gear is achieved by changing the direction of rotation of the motor 4.
In the described truck all-wheel drive, the speed of the motor is only dependent on the amount of oil, with the interposition of dis! described planetary gear in addition to an idle position two different translations are gebil det. The oil pressure should remain the same for all drive motors. If there are differences in speed, a regulating device is activated which compensates for the speed and acts as a differential lock.
The design of this regulating member is not the subject of the present invention.
