Abstract
Description
Die vorliegende Erfindung betrifft eine Portalachse für niederflurige Kraftfahrzeuge, insbesondere Niederfluromnibusse nach dem Oberbegriff des Anspruchs 1.The The present invention relates to a portal axle for low-floor Motor vehicles, in particular low-floor buses according to the preamble of claim 1.
Portalachsen werden üblicherweise bei Nahverkehrs- und Stadtbusachsen eingesetzt, um den Freiraum des Ganges im Bus möglichst groß zu gestalten. Insbesondere bei Nahverkehrsbussen sowie Stadtbussen ist zudem eine möglichst niedrige Flurhöhe wünschenswert, um den Fahrgästen ein bequemes und zügiges Ein- und Aussteigen zu ermöglichen. Hierfür werden Portalantriebe bzw. Portalachsen eingesetzt, bei welchen die Achswellen gegenüber den Radachsen um einen bestimmten Abstand, der sogenannten Portaltiefe, versetzt sind. Dieser Achsversatz wird durch jeweils ein Zwischengetriebe unmittelbar am Radantrieb, dem sogenannten Portaltrieb, ermöglicht. Auf diese Weise können z.B. Fahrgäste, insbesondere Rollstuhlfahrer oder Kinderwagen, möglichst einfach in das Fahrzeug einsteigen bzw. eingeladen werden.portal axles become common used on local and city bus axes to the free space the gear in the bus as possible big too shape. Especially with local buses and city buses is also one possible low floor height desirable, around the passengers a comfortable and fast To allow entry and exit. Therefor Portal drives or portal axes are used in which the axle shafts opposite the wheel axles by a certain distance, the so-called portal depth, are offset. This misalignment is immediately by an intermediate gearbox on the wheel drive, the so-called portal drive allows. In this way, e.g. passengers, especially wheelchair users or prams, as easy as possible in the vehicle get in or be invited.
Beispielsweise
beschreibt die
Bei Portalachsen ist die Abtriebswelle mit der Radnabe verbunden, welche mittels des Nabenträgers gelagert wird, wobei der Nabenträger den Lagersitz für die Nabenlagerung und die Befestigung für den Bremssattel bzw. den Bremsträger einer Scheibenbremse umfasst. Nach dem Stand der Technik werden im Portalgehäuse die Zwischenräder, das Antriebsrad und das Abtriebsrad des Portaltriebs über Lagerstellen fixiert; des weiteren ist üblicherwei se eine Lagerstelle des Ausgleichsgetriebes auch im Portalgehäuse angeordnet.at Portal axles, the output shaft is connected to the hub, which by means of the hub carrier is stored, wherein the hub carrier the bearing seat for the hub bearing and the attachment for the caliper or the brake carrier a disc brake covers. According to the state of the art in the portal housing the intermediate wheels, the drive wheel and the output gear of the portal drive via bearings fixed; Furthermore, it is usual a bearing point of the differential gear also arranged in the portal housing.
Nach dem Stand der Technik werden das Portalgehäuse und der Nabenträger üblicherweise miteinander verschraubt, was sich in nachteiliger Weise als aufwändig erweist, da zu diesem Zweck viele sicherheitskritische Schrauben notwendig sind.To In the prior art, the portal housing and the hub carrier are usually together bolted, which proves to be disadvantageously expensive, because for this purpose many safety-critical screws necessary are.
Aus
der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Portalachse anzugeben, bei der die Verbindung zwischen dem Nabenträger und dem Portalgehäuse hinsichtlich der Montage und der Herstellungskosten optimiert wird.Of the present invention is based on the object, a portal axis indicate at which the connection between the hub carrier and the portal housing is optimized in terms of assembly and manufacturing costs.
Diese Aufgabe wird durch die Merkmale der unabhängigen Patentansprüche 1, 7 und 10 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den entsprechenden Unteransprüchen hervor.These The object is achieved by the features of the independent patent claims 1, 7 and 10 solved. Further Embodiments of the invention and advantages will be apparent from the corresponding subclaims.
Gemäß einer ersten Ausführungsform der Erfindung wird vorgeschlagen, den Nabenträger und das Portalgehäuse als eine Einheit auszubilden, wodurch die aus dem Stand der Technik bekannte Verschraubung entfällt und die Herstellungskosten sowie der Montageaufwand in vorteilhafter Weise reduziert werden.According to one first embodiment the invention is proposed, the hub carrier and the portal housing as to form a unit, whereby those from the state of the art Known screw eliminates and the manufacturing cost and assembly costs in an advantageous Be reduced.
Hierbei können Nabenträger und Portalgehäuse einteilig ausgebildet sein, vorzugsweise durch ein Gussverfahren. Es ist erfindungsgemäß auch möglich, dass der Nabenträger und das Portalgehäuse zunächst separat hergestellt werden und anschließend miteinander verschweißt werden. Durch diese Konzeption können unterschiedliche Werkstoffe für das Portalgehäuse und den Nabenträger gewählt werden, wodurch eine optimale Funktionalität des Lagersitzes der Radlagerung erzielbar ist, wenn der Nabenträger nicht aus Gussmaterial hergestellt ist.in this connection can hub carrier and portal housing be formed in one piece, preferably by a casting process. It is according to the invention also possible that the hub carrier and the portal housing first be prepared separately and then welded together. Through this conception can different materials for the portal housing and the hub carrier to get voted, whereby optimal functionality of the bearing seat of the wheel bearing achievable when the hub carrier not made of cast material.
Gemäß einer weiteren Ausführungsform der Erfindung können der Nabenträger und das Portalgehäuse zweiteilig ausgeführt werden, wobei die Verbindung von Portalgehäuse und Nabenträger über einen Presssitz erfolgt. Die axiale Sicherung des Nabenträgers wird durch eine Verschraubung über eine Hutmutter am radseitigen Ende des Nabenträgers und den Anschlag des Nabenträgers zusätzlich verstärkt. Vorzugsweise ist die radseitige Lagerung des Abtriebsrades im Portalgehäuse untergebracht; sie kann aber im Rahmen einer weiteren Ausführungsform im Nabenträger angeordnet sein, was auch in dem Vorteil resultiert, dass die Lagerung als zusätzliche Sicherung gegen ein axiales Wandern des Nabenträgers dient.According to one another embodiment of the invention the hub carrier and the portal housing executed in two parts be, with the connection of portal housing and hub carrier over a Press fit done. The axial securing of the hub carrier is through a screw connection over a cap nut at the wheel end of the hub carrier and the stop of the hub carrier additionally reinforced. Preferably the wheel-side mounting of the output gear is housed in the portal housing; but it can be arranged in a further embodiment in the hub carrier be, which also results in the advantage that the storage as additional Securing against axial migration of the hub carrier is used.
Gemäß einer weiteren Ausführungsform der Erfindung erfolgt die Verbindung von Nabenträger und Portalgehäuse über eine Profilverbindung. Diese Konstruktion weist den Vorteil auf, dass die Verbindung von Nabenträger und Portalgehäuse lösbar ist.According to one another embodiment the invention, the connection of hub carrier and portal housing via a Profile connection. This construction has the advantage that the connection of hub carrier and portal housing solvable is.
In vorteilhafter Weise kann der Bremsträger der Bremseinrichtung am Portalgehäuse befestigt sein. Im Rahmen einer besonders vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, die Lagerung des Abtriebsrades des Portaltriebs in Tandem-Anordnung zu realisieren, was in einer besonders kompakten Bauweise resultiert. Zur Schmierung der Lagerung des Abtriebsra des ist ein mit dem Ölsumpf verbundener Ölkanal vorgesehen, mittels dessen das Spritzöl, welches durch die Zahneingriffe entsteht, an die Lager gebracht wird. Dies ist insbesondere wichtig, da der Ölsumpf niedriger liegt, als die zu schmierenden Lager. Im Rahmen weiterer Ausführungsformen kann die Lagerung des Abtriebsrades auch über eine X- oder O-Anordnung erfolgen.Advantageously, the brake carrier of the braking device attached to the portal housing be. In a particularly advantageous embodiment of the invention, it is proposed to realize the storage of the output gear of the gantry drive in tandem arrangement, resulting in a particularly compact design. For lubrication of the storage of the Abtriebsra a connected to the oil sump oil passage is provided by means of which the spray oil, which is produced by the meshing, is brought to the camp. This is particularly important because the oil sump is lower than the bearings to be lubricated. In the context of further embodiments, the bearing of the output gear can also take place via an X or O arrangement.
