Die Erfindung bezieht sich auf ein Radnabengetriebe, wie es im Oberbegriff des Hauptanspruches beschrieben ist.The invention relates to a wheel hub transmission as it is in The preamble of the main claim is described.

Es sind. Radnaben der oben beschriebenen Art bekannt, bei denen in der Nabe oder dem Getriebegehäuse Innenbackenbremsen vorgesehen sind. Diese Anordnung erfordert verhältnismäßig viel Platz; außerdem sind Innenbackenbremseh, ihre Lagerung und Betatigungseinrichtung relativ vielteilig und teuer.There are. Known wheel hubs of the type described above, in which Internal shoe brakes are provided in the hub or the gearbox housing are. This arrangement requires a relatively large amount Place; there are also internal shoe brakes, their storage and actuation device relatively multi-part and expensive.

Bei elektrisch angetriebenen Radnaben ist es auch bekannt geworden, die Welle des an der Nabe angeordneten Elektromotors auf der der Nabe abgekehrten Seite zu verlängern, so-daß diese Welle aus dem Motorgehäuse herausragt. Die Bremse ist an diesem Wellenstummel vorzusehen. Diese Anordnung ergibt einen größeren Schwenkradius der Radnabe, was einen größeren Platzbedarf für das" Fahrzeug zur Folge hat, was wiederum die Notwendigkeit nach sich zieht, beispielsweise in den zu befahrenden Magazinen die Gänge zwischen den Regalen entsprechend breit zu machen,! Der Inhalt des Magazins ist also gewissermaßen vom Schwenkradius der Radnabe abhängig. .In the case of electrically driven wheel hubs it has also become known, the shaft of the electric motor arranged on the hub to extend on the side facing away from the hub, so that this Shaft protrudes from the motor housing. The brake is to be provided on this stub shaft. This arrangement gives one larger swivel radius of the wheel hub, which requires a larger space for the "vehicle, which in turn entails the need, for example in the magazines to be driven through, the aisles between the shelves correspondingly wide close,! The content of the magazine is, so to speak, dated Swivel radius of the wheel hub dependent. .

Der Erfindung liegt die Aufgabe zugrunde, den Schwenkradius der Radnabe zu verkleinern und damit den Platzbedarf des Fahrzeugs, z.B. Staplers, zu verringern. The invention is based on the object of the pivot radius reduce the size of the wheel hub and thus reduce the space required by the vehicle, e.g. forklift truck.

Die der Erfindung zugrunde liegende Aufgabe wird mit den Merk-The object on which the invention is based is

malen des Hauptanspruches gelöst. Eine besonders, gedrängte Bauweise ergeben die Merkmale des Anspruchs 2, wobei mit den Merkmalen des Anspruchs 3 optimale Verhältnisse erzielbar sind. Bezüglich der Betätigung der Bremse ist eine Ausgestaltung mit den Merkmalen des Anspruch 4 vorteilhaft.paint the main claim solved. A special, compact design result in the features of claim 2, with the features of claim 3 optimal conditions can be achieved. With regard to the actuation of the brake, an embodiment with the features of claim 4 is advantageous.

Die Erfindung ist anhand einer Skizze beschrieben.The invention is described using a sketch.

Mit 1 ist eine Radnabe bezeichnet, auf der der Reifen 2 in bekannter Veise befestigt ist. Das Rad ist zum Zwecke des Lenkens des Fahrzeugs um eine Schwenkachse 3 schwenkbar angeordnet, die etwa durch die Mitte des Reifens verläuft. Die Schwenkbewegung wird ausgeführt von einem Flansch k o. dgl., der drehbar am nicht gezeichneten Fahrgestell gelagert und zum Lenken antreibbar ist. An den Flansch ist der zum Antrieb des Rades dienende Elektromotor 5 angeschraubt. Die Welle 6 des Elektromotors ragt durch den Flansch 4 hindurch und ist an ihrem äußeren Ende mit einer Verzahnung versehen. Mit dieser Verzahnung kämmt ein Zahnrad 8 eines Zahnradblockes, dessen zweites Zahnrad 9 mit der Verzahnung eines Zwischenrades 10 kämmt. Diese Verzahnung greift in ein Ringrad 11 ein, das als das Getriebe umschließende Gehäuse 12 ausgebildet ist, oder das in einem solchen Getriebe befestigt ist. Das Gehäuse 12 und die Radnabe 1 sind miteinander verschraubt. Zur Lagerung des besagten Zahnradblockes und des. Zwischenrades sind in dem Flansch. Bolzen 13» I^ befestigt. Einige dieser Bolzen 13 sind über die Zahnradblöcke 8,9 hinaus verlängert. Hier greifen Außenlamellen 15 einer Lamellenbremse ein. Die Außenlamellen sind zu diesem Zweck am Umfang mit zu den Bolzen passenden Aussparungen versehen. Sie1 with a wheel hub is referred to, on which the tire 2 is attached in a known Veise. For the purpose of steering the vehicle, the wheel is arranged to be pivotable about a pivot axis 3 which runs approximately through the center of the tire. The pivoting movement is carried out by a flange k or the like, which is rotatably mounted on the chassis (not shown) and can be driven for steering. The electric motor 5 used to drive the wheel is screwed onto the flange. The shaft 6 of the electric motor protrudes through the flange 4 and is provided with teeth at its outer end. A gear 8 of a gear block, the second gear 9 of which meshes with the teeth of an intermediate gear 10, meshes with this toothing. This toothing engages in a ring gear 11, which is designed as a housing 12 surrounding the gear, or which is fastened in such a gear. The housing 12 and the wheel hub 1 are screwed together. To support said gear block and the intermediate gear are in the flange. Bolt 13 »I ^ attached. Some of these bolts 13 are extended beyond the gear blocks 8, 9. Outer disks 15 of a multi-disk brake intervene here. For this purpose, the outer disks are provided on the circumference with recesses that match the bolts. she

sind axial zu den Zentralrädern angeordnet. In die Verzahnung der Welle 6 greifen in bekannter Weise Innenlamellen l6 ein, die in bekannter Weise mit den Außenlamellen zusammenarbeiten. Vor der äußersten Außenlamelle ist ein Druckstück 17 angeordnet, das mit einem zentralen Zapfen l8 versehen ist. Dieser Zapfen ist in der Radnabe 1 nach außen ragend gelagert. Zur Lagerung können, falls erforderlich, gesonderte Lager und Dichtelemente vorgesehen sein, die nicht gezeichnet sind. An dem Zapfen liegt ein Schenkel 19 eines Winkelhebels 20 an, der am Flansch 4 drehbar gelagert ist. Der zweite Schenkel 21 dieses Winkelhebels ist so angeordnet, daß er vom Fahrgestell aus mit einem Betätigungsorgan betätigt werden kann, ohne daß die Schwenkbewegung des Flansches gestört wird, zu diesem Zweck ist in dem zweiten Schenkel 21 eine Bohrung 22 vorgesehen, die axial zur Schwenkachse 3 liegt und in die das Betätigungsorgan eingreift.are arranged axially to the central gears. Inner disks l6 engage in the toothing of shaft 6 in a known manner, which work together in a known manner with the outer discs. A pressure piece 17, which is provided with a central pin l8, is arranged in front of the outermost outer lamella. This The pin is mounted in the wheel hub 1 so as to protrude outwards. If necessary, separate bearings and Sealing elements may be provided that are not shown. At A leg 19 of an angle lever 20, which is rotatably mounted on the flange 4, rests against the pin. The second leg 21 of this Angle lever is arranged so that it can be operated from the chassis with an actuator without the Pivoting movement of the flange is disturbed for this purpose a bore 22 is provided in the second leg 21, which is axially to the pivot axis 3 and into which the actuating member intervenes.

Wird an dem besagten Betätigungsorgan gezogen, dann führt der Winkelhebel eine Schwenkbewegung aus. Dabei drückt der Schenkel 19 auf den Zapfen l8 und damit auf das Druckstück 17, das die Außen- und Innenlamellen aufeinanderpreßt, wodurch die rotierende Welle 6 bzw. das rotierende Rad 1, 2 gegenüber dem nicht rotierenden Flansch 4 mit den Bolzen 13 abgebremst wird.If the said actuator is pulled, then the Angle lever from a pivoting movement. The leg 19 presses on the pin l8 and thus on the pressure piece 17, the the outer and inner lamellae presses against each other, whereby the rotating shaft 6 or the rotating wheel 1, 2 is braked relative to the non-rotating flange 4 with the bolts 13.

Dadurch daß die Bremseinrichtung eine wesentlich geringere Entfernung von der Schwenkachse 3 hat als das äußere Lagerschild 23 des Elektromotors, wird der Schwenkradius des Rades trotz axialer Anordnung durch die Bremseinrichtung nicht vergrößert. As a result, the braking device is a much smaller one Distance from the pivot axis 3 than the outer bearing plate 23 of the electric motor becomes the pivot radius of the wheel not enlarged despite the axial arrangement by the braking device.
