Demnach wird eine Antriebsachse mit einem Einzelradantrieb für jedes der beiden Antriebsräder vorgeschlagen, wobei jeder Einzelradantrieb einen koaxial zur Antriebsachse angeordneten Elektromotor, eine Bremseinrichtung und ein Getriebe umfasst und wobei das jeweilige Antriebsrad direkt mit der Abtriebsstufe des Getriebes verbunden ist. Hierbei ist die Radlagerung gleichzeitig die Abtriebswellenlagerung und die Abtriebsstufe ist im wesentlichen an der Innenseite des Antriebsrades angeordnet. Accordingly, a drive axle with a Independent wheel drive proposed for each of the two drive wheels where each independent wheel drive is coaxial with Drive axis arranged electric motor, a braking device and a Gearbox includes and the respective drive wheel directly is connected to the output stage of the transmission. in this connection the wheel bearing is also the output shaft bearing and the output stage is essentially on the inside arranged the drive wheel.

Durch die Verwendung eines Elektromotors wird die Belastung der Umwelt signifikant reduziert. Zudem wird insbesondere in axialer Richtung wenig Bauraum beansprucht, so dass eine Verwendung bei Arbeitsbühnen sehr vorteilhaft ist. Außerdem ist durch den Einzelradantrieb eine hohe Wendigkeit in engsten Räumen gewährleistet. By using an electric motor, the Significantly reduced environmental impact. In addition, takes up little space, especially in the axial direction, so that use on work platforms is very beneficial is. In addition, the single wheel drive makes it a high one Maneuverability guaranteed in the tightest of spaces.

Die Erfindung wird im folgenden anhand der beigefügten Figuren näher erläutert. The invention is described below with reference to the accompanying Figures explained in more detail.

Es stellen dar: They represent:

Fig. 1 eine Schnittansicht einer bevorzugten Ausführungsform der erfindungsgemäßen Antriebsachse und Fig. 1 is a sectional view of a preferred embodiment of the drive shaft according to the invention and

Fig. 2 eine Schnittansicht einer zweiten bevorzugten Ausführungsform der erfindungsgemäßen Antriebsachse. Fig. 2 is a sectional view of a second preferred embodiment of the drive axle according to the invention.

Gemäß Fig. 1 ist für jedes Antriebsrad ein Elektromotor 1 vorgesehen, der koaxial zur Antriebsachse angeordnet ist, dessen Antriebsleistung mittels eines Antriebsritzels 2 über ein Getriebe 3 mit zwei Stirnradstufen 4, 5 auf die Antriebsräder 6 übertragen wird, wobei die Antriebsräder 6 direkt mit der Abtriebsstufe 5 des Getriebes 3 verbunden sind. Hierbei ist die Abtriebsstufe 5 im wesentlichen an der Innenseite des Antriebsrades 6 angeordnet. Referring to FIG. 1, an electric motor 1 is provided for each drive wheel, which is arranged coaxially to the drive shaft, the drive power is transmitted by means of a drive pinion 2 via a gearbox 3 with two spur-gear stages 4, 5 to the drive wheels 6, wherein the drive wheels 6 directly with the Output stage 5 of the transmission 3 are connected. Here, the output stage 5 is arranged essentially on the inside of the drive wheel 6 .

Ferner ist für jedes Antriebsrad 6 eine Bremseinrichtung 7 vorgesehen, welche auf die Motorwelle eingreift und in Richtung des Antriebsrades koaxial zum Elektromotor 1 angeordnet ist. Furthermore, a braking device 7 is provided for each drive wheel 6 , which engages the motor shaft and is arranged coaxially to the electric motor 1 in the direction of the drive wheel.

Durch diese Konzeption werden die Radkräfte direkt über das Abtriebslager 8 zur Lenk- bzw. Rahmenbefestigung geleitet, so dass der Elektromotor 1 von den Radkräften nicht beeinflusst wird. As a result of this concept, the wheel forces are passed directly via the output bearing 8 to the steering or frame mounting, so that the electric motor 1 is not influenced by the wheel forces.

Die Abtriebswelle 9 ist vorzugsweise mittels eines UNIPAC-Lagers gelagert; ferner ist ein Sicherheitsring zur axialen Sicherung vorgesehen. Das mit der Abtriebswelle 9 verbundene Stirnrad 10 der Abtriebs- bzw. Stirnradstufe 5 ist über einen Kegelschrumpfsitz mit der Zwischenwelle 11 der Stirnradstufe 4 verbunden. The output shaft 9 is preferably mounted by means of a UNIPAC bearing; a safety ring for axial securing is also provided. The spur gear 10 of the output or spur gear stage 5 connected to the output shaft 9 is connected to the intermediate shaft 11 of the spur gear stage 4 via a conical shrink fit.

Als Elektromotoren können bürstenlose Gleichstrom- und/oder Wechselstrommotoren verwendet werden, wobei die A- Lagerseite des Motors ist in das Getriebe teilintegriert sein kann. Brushless direct current and / or AC motors are used, the A- The bearing side of the motor is partially integrated in the gearbox can be.

In Fig. 2 ist eine weitere bevorzugte Ausführungsform der erfindungsgemäßen Antriebsachse dargestellt, deren Bauweise in axial Richtung sehr kompakt ist. In Fig. 2 shows another preferred embodiment of the drive axle according to the invention whose construction is very compact in axial direction.

Dies wird dadurch realisiert, dass die Abtriebsstufe 5 im Hohlraum der Radfelge 12 angeordnet ist. Des weiteren ist die Bremseinrichtung 7, die vorzugsweise als elektromagnetische Federkraftbremse ausgebildet ist, an der B- Lagerseite des Elektromotors 1 koaxial angeordnet. This is realized in that the output stage 5 is arranged in the cavity of the wheel rim 12 . Furthermore, the braking device 7 , which is preferably designed as an electromagnetic spring-applied brake, is arranged coaxially on the B bearing side of the electric motor 1 .

Wie in Fig. 2 gezeigt, ist die Zwischenwelle 11 mittels Nadellager mit Innen- und Außenring geführt. Durch die Anordnung gemäß Fig. 2 ist das Abtriebslager 8 zur Aufnahme der Radkräfte sehr effektiv angeordnet. As shown in Fig. 2, the intermediate shaft 11 is guided by means of needle bearings with an inner and outer ring. By the arrangement according to FIG. 2, the output bearing 8 is disposed very effective for receiving the wheel forces.

Um größere Übersetzungswerte zu erzielen, kann die Verzahnung des Antriebsritzels 2 direkt auf der Motorwelle aufgebracht sein. In order to achieve larger transmission ratios, the toothing of the drive pinion 2 can be applied directly to the motor shaft.

Die hier vorgestellte Antriebsachse kann erfindungsgemäß in vorteilhafter Weise bei Arbeitsbühnen eingesetzt werden, da sie aufgrund der kompakten Bauweise, des hohen Wirkungsgrades sowie der Wendigkeit und der Servicefreundlichkeit bestens dazu geeignet ist. Bezugszeichen 1 Elektromotor
