Abstract

The steering or non-steering axle has a spur pinion(3,4) on the end of each half or universal-jointed shaft. This meshes with two similar parallel spur pinions(5,6,7,8) at diametrally opposite positions, but with double the tooth width. These mesh with a gearwheel(9,10) on the axle shaft(11), giving a centre distance between the latter and the half-shaft of 6 to 9 cm. By splitting the drive, loads on all gear teeth are halved. ADVANTAGE - high ground clearance, while keeping chassis height and centre of gravity low.

Description

       

  
 



  Gegenstand vorliegender Erfindung ist eine Lenktriebachse und ungelenkte Triebachse für hangtaugliche Geländetransporter und Nutzfahrzeuge mit vielseitigem Einsatz. 



  Bei diesen auf Strassen und im Gelände im Einsatz stehenden Nutzfahrzeugen kennt man heute 3 verschiedene Bauarten von Triebachsen. 



  Die direkt angetriebene Achse hat eine gemeinsame Mittellinie für Fahrachse und Differential. Darum ist die Bodenfreiheit unter dem Ausgleichsgetriebe sehr klein und ungenügend. Ein weiterer Nachteil sind die starkbelasteten Triebwerksteile: Kegelradritzel, Tellerrad, Ausgleichsgetriebe, Seitenwellen und Gelenkwellen. 



  Durch die Planetentriebachse werden die Triebwerksteile entlastet da eine Untersetzung in den Radnaben stattfindet. Eine genügende Bodenfreiheit wird aber durch diese Bauart kaum erreicht, da auch hier die Differentialmittellinie mit derjenigen der Fahrachse identisch ist. 



  Durch die meist bekannte und bewährte Ritzelachse oder Portalachse ist die Triebwerkentlastung zum grossen Teil gelöst und diese Bauart ermöglicht auch eine grosse Bodenfreiheit. Hingegen wirkt sich die allzugrosse Achsversetzung des Differentials mit der ganzen Achsbrücke  nach oben nachteilig aus, da auch der Schwerpunkt des ganzen Fahrzeuges nach oben verlagert wird. 



  Durch die hohe Plazierung der Geräte und Aufbauten sowie des Ladegutes wird die Kippgefahr begünstigt. Diese Situation verschlechtert das Fahrverhalten der schnellfahrenden Portalachsenfahrzeuge. 



  Die vorliegende Erfindung setzt sich zum Ziel Triebachsen zu bauen, welche folgende Merkmale aufweisen:
 - hohe Zugkraft, die sich in jedem Rad entwickelt
 - geringe Belastung für alle Triebwerkteile
 - optimale Bodenfreiheit
 - geringe Fahrzeugrahmenhöhe
 - günstige Schwerpunkthöhe
 - hohe Teilegleichheit 



  Die erfindungsgemässe Lösung ist in der Kennzeichnung des Patentanspruchs definiert. Im folgenden wird ein Ausführungsbeispiel anhand Zeichnung beschrieben. 
 
   Fig. 1 zeigt eine Triebachse in Fahrtrichtung gesehen 
   Fig. 2 zeigt die Anordnung der Zahnräder für den Radan trieb. Seitenansicht. 
 



   In jedem Radantrieb sind 2 von der Differentialwelle 1 oder von der Gelenkwelle 2 angetriebene Stirnritzel 3, 4 vorhanden. Zwei Parallelritzel 5, 6 oder 7, 8 mit doppelter Zahn breite greifen um 180 DEG  gegenüber an 2 Stellen in das Stirnritzel und übertragen die Umfangskraft durch je 2 Zahneingriffe auf das Stirnrad 9, 10, welche über die Fahrachse 11 drehfest mit dem Triebrad verbunden sind und diese antreiben. 



  Durch die Anordnung der Zahnräder wird eine Untersetzung erreicht, welche das Drehmoment erhöht und nur einen geringen Achsabstand zwischen Fahrachse 11 und Differentialmittellinie erfordert. Daraus ergibt sich die optimale Bodenfreiheit. Die weiteren Vorteile sind: geringe Höhe des Fahrzeugrahmens, günstige Schwerpunktlage, geringe Bela- stung aller Triebwerksteile und hohe Teilegleichheit, die die Fertigung vereinfacht. 



  
 



  The present invention relates to a steering drive axle and an unguided drive axle for terrain transporters suitable for slopes and commercial vehicles with versatile use.



  These commercial vehicles, which are used on roads and off-road, are now known to have 3 different types of drive axles.



  The directly driven axle has a common center line for the travel axle and differential. Therefore, the ground clearance under the differential is very small and insufficient. Another disadvantage is the heavily loaded engine parts: bevel gear pinion, ring gear, differential, side shafts and cardan shafts.



  The parts of the engine are relieved by the planetary drive axle because there is a reduction in the wheel hubs. Sufficient ground clearance is hardly achieved with this type of construction, since here too the differential center line is identical to that of the driving axle.



  The mostly well-known and proven pinion axle or portal axle relieves the engine load to a large extent and this design also enables a large ground clearance. On the other hand, the all-too-large axle offset of the differential with the entire axle bridge upwards has a disadvantageous effect, since the center of gravity of the entire vehicle is also shifted upwards.



  Due to the high placement of the devices and superstructures as well as the load, the risk of tipping is increased. This situation worsens the driving behavior of the high-speed portal axle vehicles.



  The present invention aims to build drive axles which have the following features:
 - high traction that develops in every wheel
 - low load for all engine parts
 - optimal ground clearance
 - low vehicle frame height
 - favorable center of gravity
 - high level of parts



  The solution according to the invention is defined in the characterizing part of the patent claim. An exemplary embodiment is described below with reference to the drawing.
 
   Fig. 1 shows a drive axis seen in the direction of travel
   Fig. 2 shows the arrangement of the gears for the Radan driven. Side view.
 



   In each wheel drive there are 2 spur gears 3, 4 driven by the differential shaft 1 or by the cardan shaft 2. Two parallel pinions 5, 6 or 7, 8 with double tooth width engage by 180 DEG opposite at 2 points in the spur pinion and transmit the circumferential force by 2 tooth meshes on the spur gear 9, 10, which are rotatably connected to the drive wheel via the travel axis 11 and drive them.



  The arrangement of the gears achieves a reduction which increases the torque and only requires a small center distance between the driving axis 11 and the differential center line. This results in the optimal ground clearance. The other advantages are: low height of the vehicle frame, favorable center of gravity, low load on all engine parts and high level of parts, which simplifies production.
