Abstract
Description
Die Erfindung betrifft eine Antriebsachse mit einem in einem Antriebsachsengehäuse befindlichen Fahrmotor, einer von diesem angetriebenen Hohlwelle, einer Bremsvorrichtung und mit einem Differentialgetriebe, von dessen Ausgängen jeweils eine Abtriebswelle zu einem Achsende der Antriebsachse hin führt, wobei die Hohlwelle und das Differentialgetriebegehäuse gegenüber dem Antriebsachsengehäuse abgestützt sind.The The invention relates to a drive axle with a traction motor located in a drive axle housing, a driven by this hollow shaft, a braking device and with a differential gear, from whose outputs each an output shaft leads to an axle end of the drive axle, wherein the hollow shaft and the differential gear housing are supported relative to the drive axle housing.
Ein
Gegenstand der eingangs genannten Art ist in der Gebrauchsmusterschrift
Es ist Aufgabe der vorliegenden Erfindung, eine Antriebsachse der eingangs genannten Art insbesondere bezüglich der Herstellungskosten zu verbessern und kompakt zu bauen.It Object of the present invention, a drive axle of the beginning in particular with regard to to improve the manufacturing costs and to build compact.
Die Aufgabe wird gelöst durch eine Antriebsachse, deren Differentialgetriebe als selbstsperrendes Differentialgetriebe und deren Bremsvorrichtung zur direkten Einwirkung auf das Differentialgetriebegehäuse ausgebildet sind. Die erfindungsgemäße Antriebsachse baut deutlich kleiner als herkömmliche Antriebsachsen, da die Bremsvorrichtung zentral und kompakt im Bereich des Differentialgetriebes angeordnet werden kann. Der Verzicht auf zwei den Abtriebswellen zugehörigen Bremseinheiten verringert die Herstellungskosten deutlich, wobei aufgrund des selbstsperrenden Differentials auch bei schlechtem, beispielsweise rutschigem Untergrund keine Nachteile bezüglich der Bremsleistung in Kauf genommen werden müssen. Da es sich um ein passiv gesperrtes Differentialgetriebe handelt, bedarf es weiterhin keiner aufwendigen elektronischen Steuerung des Differentialgetriebes. Die Bremskräfte, die während eines Bremsvorgangs aufgebracht werden, beziehungsweise die die Bremskräfte ausübenden Teile der Bremsvorrichtung liegen zentral an dem Differentialgehäuse an, wodurch beide Abtriebswellen gleichmäßig gebremst werden.The Task is solved by a drive axle whose differential gear as a self-locking Differential gear and its braking device for direct action on the differential gear housing are formed. The drive axle according to the invention builds significantly smaller than conventional drive axles, because the braking device central and compact in the range of the differential gear can be arranged. The waiver of two output shafts associated Brake units significantly reduces manufacturing costs, with due to the self-locking differential even in bad, for example slippery surface no disadvantages regarding the braking performance in Purchase must be taken. Since it is a passive locked differential gear, it still requires no complex electronic control of the differential gear. The braking forces applied during a braking operation be, or the braking forces exerting parts of the braking device are centrally located on the differential housing, whereby both output shafts evenly braked become.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht eine Antriebsachse vor, deren Hohlwelle einenends über ein herkömmliches Festlager gelagert ist und anderenends unter Verzicht auf ein weiteres Festlager mittelbar über ein Untersetzungsgetriebe gegenüber dem Antriebsachsengehäuse abgestützt ist. Durch die Reduktion der zwei Festlager auf nur ein Festlager werden die Herstellungskosten weiter verringert und die Antriebsachse kann kompakter gebaut werden. Darüber hinaus hat es sich gezeigt, daß bei geringerer Wärmeentwicklung der Wirkungsgrad der Antriebsachse aufgrund der einfach gelagerten Motorwelle verbessert ist.A Further advantageous embodiment of the invention provides a drive axle before, whose hollow shaft at one end a conventional one Fixed bearing is stored and the other, waiving another Fixed storage indirectly via a reduction gear opposite is supported the drive axle housing. By reducing the two fixed bearings to just one fixed bearing the manufacturing costs further reduced and the drive axle can be more compact be built. About that In addition, it has been shown that at lower heat development of Efficiency of the drive axle due to the simply mounted motor shaft is improved.
Während sich die direkte und die mittelbare Lagerung der Hohlwelle vorteilhafterweise in den unmittelbaren Endbereichen der Hohlwelle befinden, umfaßt die Erfindung auch solche Antriebsachsen, deren Hohlwelle auch von den Endbereichen beabstandet gelagert ist.While the direct and indirect storage of the hollow shaft advantageously located in the immediate end portions of the hollow shaft, embraces the invention Also such drive axles whose hollow shaft and spaced from the end regions is stored.
Bevorzugt ist das dem Motor direkt nachgeschaltete Untersetzungsgetriebe als Planetengetriebe mit zumindest einer Planetenstufe ausgebildet, wobei aufgrund der koaxialen Anordnung von Sonnenrad des Planetengetriebes und Hohlwelle eine kompakte und platzsparende Anordnung des Untersetzungsgetriebes im Antriebsachsengehäuse erreicht wird. Die Hohlwellenlagerung erhält dadurch gegenüber herkömmlichen Lagerungen über zwei direktwirkende Lager durch die selbstzentrierende Wirkung des Planetengetriebes die notwendige Stabilität.Prefers is the engine directly downstream reduction gear as Planetary gear formed with at least one planetary stage, wherein due to the coaxial arrangement of sun gear of the planetary gear and hollow shaft a compact and space-saving arrangement of the reduction gear in the drive axle housing is reached. The hollow shaft bearing is replaced by conventional Storage over two direct acting bearings due to the self - centering effect of the Planetary gearbox the necessary stability.
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Stege bzw. Planetenträger des Planetengetriebes als Teil des Differentialgetriebegehäuses ausgebildet. Das Plantetengetriebe ist zwischen Fahrmotor und Differentialgetriebe angeordnet, so daß der Kraftfluß vom Fahrmotor über die Hohlwelle auf das Planetengetriebe stattfindet und von dort weiter auf das Differentialgetriebe. Von diesem verlaufen dessen Abtriebswellen zu den jeweiligen Endbereichen der Antriebsachse, um dort letztlich die Räder anzutreiben. Die Abtriebswellen des Differentialgetriebes, von denen eine koaxial zur Hohlwelle durch diese hindurch verläuft, sind demnach auch als Antriebswellen zu bezeichnen. Die Kombination von einer Planetenstufe und einem Differentialgetriebe in einer akzeptablen Drehzahlspanne führt zu einem hohen Wirkungsgrad des Antriebs bei gleichzeitig verminderter Geräuschentwicklung, wobei insbesondere die mögliche Verknüpfung von Planetenträger bzw. Steg und Differentialgetriebegehäuse bzw. -korb zu einer Einsparung an Teilen führt und damit die Herstellungskosten der erfindungsgemäßen Antriebsachse weiter reduziert werden.at a further advantageous embodiment of the invention are the Webs or planet carrier the planetary gear formed as part of the differential gear housing. The planetary gearbox is between traction motor and differential gear arranged so that the Power flow from Traction engine over the Hollow shaft takes place on the planetary gear and from there on on the differential gear. From this run its output shafts to the respective end regions of the drive axle, to ultimately there the wheels drive. The output shafts of the differential gear, of which a coaxial with the hollow shaft passing therethrough are Accordingly, to be referred to as drive shafts. The combination of a planetary stage and a differential gear in an acceptable Speed range leads to a high efficiency of the drive at the same time reduced Noise, wherein in particular the possible shortcut from planet carrier or web and differential gear housing or basket to a saving leads to parts and so that the manufacturing cost of the drive axle according to the invention further reduced become.
