Description
Man hat für Kraftfahrzeuge schon einen Zahnradantrieb gewählt, bei welchem die Laufräderpaare durch getrennte Wellen angetrieben werden und die zu einem Rahmen vereinigten Achsengehäuse -bzw. die Schubbalken mit dem Wagenrahmen durch ein Kugelgelenk verbunden sind. Bei solchen Fahrzeugen liegt das zum Ausgleich zwischen den Rädern eines Laufräderpaares dienende DifferentialgetriebeA gear drive has already been chosen for motor vehicles in which the pairs of running wheels are driven by separate shafts and united to form a frame Axle housing or the push beam is connected to the carriage frame by a ball joint are. In such vehicles, the differential gear used for balancing is located between the wheels of a pair of running wheels
ίο gewöhnlich zwischen der Laufradachse und dem Kugelgelenk. Infolgedessen haben das Gehäuse des Differentialgetriebes und dessen Verbindungsrohre nicht unerhebliche Biegungsmomente aufzunehmen, und die durch die gen Querschnittsabmessungen bedingte Geichtsvermehrung vergrößert den durch die nicht gefederte Masse des Antriebsmechanismus herbeigeführten Nachteil des Ausschiagens und Abnutzens der Teile, so daß ein frühzeitiges Auswechseln vieler Teile erforderlich ist.ίο usually between the wheel axle and the ball joint. As a result, the housing of the differential gear and its Connecting pipes absorb not inconsiderable bending moments, and through the Facial increase due to cross-sectional dimensions increases the disadvantage of deflection caused by the unsprung mass of the drive mechanism and Wear of the parts, so that early replacement of many parts is necessary.
Diesem Übelstande wird gemäß der Erfindung dadurch abgeholfen, daß bei einem Zahnradantrieb der erwähnten Art das in den Antrieb eingeschaltete Differentialgetriebe in dem Schwingungsmittelpunkt des Kugelgelenkes angeordnet ist. Bei einer solchen Anordnung bildet das Kugelgelenk gleichzeitig das Gehäuse des Differentialgetriebes, und die Verbindungsrohre und das Gehäuse werden lediglieh durch Schubkräfte auf Zug und Druck beansprucht. Die nicht gefederte Masse des Antriebs ist hierbei wesentlich kleiner als bei den bekannten Konstruktionen und daher derThis disadvantage is remedied according to the invention in that in a gear drive of the type mentioned, the differential gear connected to the drive is arranged in the center of oscillation of the ball joint is. In such an arrangement, the ball joint forms the housing at the same time of the differential gear, and the connecting pipes and the housing become single stressed by shear forces in tension and compression. The unsprung mass of the drive is much smaller than with the known constructions and therefore the
Verschleiß der Antriebsteile wesentlich geringer. Significantly less wear of the drive parts.
Auf der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt. Two exemplary embodiments of the subject matter of the invention are shown in the drawing.
Fig. ι veranschaulicht einen Antrieb der in Frage stehenden Art mit gegeneinander geneigten Antriebswellen, undFig. Ι illustrates a drive of the type in question with mutually inclined Drive shafts, and
Fig. 2 einen solchen Antrieb mit parallelen Antriebswellen.Fig. 2 shows such a drive with parallel drive shafts.
Bei der Ausführungsform nach Fig. 1 treibt die Welle« durch Zahnräder b und c das Achsenkreuz d eines Differentialgetriebes an. Die Differentialräder f und g dieses Differentialgetriebes stehen in Eingriff mit Zahnrädern h und i auf den Enden der gegeneinander geneigten Antriebswellen k und m. In the embodiment according to FIG. 1, the shaft «drives the axles d of a differential gear through gears b and c. The differential gears f and g of this differential gear mesh with gears h and i on the ends of the mutually inclined drive shafts k and m.
Mit dem Lager der Welle α ist fest verbunden eine um den Mittelpunkt des Achsenkreuzes d des Differentialgetriebes gewölbte Kugelschale n, welche an denjenigen Stellen, an denen das Achsenkreuz des Differential- *>5 getriebes durch die Kugelschale hindurchgeführt ist, Aussparungen n' besitzt.Fixed to the bearing of the shaft α is a spherical shell n arched around the center point of the axles d of the differential gear , which has recesses n ' at those points where the axles of the differential gear is passed through the spherical shell.
Die feststehende Kugelschale η wird von einer beweglichen Kugelschale ο umgriffen, in welcher das Achsenkreuz d des Differentialgetriebes und die beiden gegeneinander geneigten Antriebswellen k und m gelagert sind. Der Schwingungsmittelpunkt des so gebildeten Kugelgelenkes liegt also im Mittelpunkt des Achsenkreuzes d des Differentialgetriebes. Das Kugelgelenk kann daher um die QuerachseThe fixed spherical shell η is encompassed by a movable spherical shell ο , in which the axis cross d of the differential gear and the two mutually inclined drive shafts k and m are mounted. The center of oscillation of the ball joint formed in this way is therefore in the center of the axis cross d of the differential gear. The ball joint can therefore around the transverse axis
des Differentialgetriebes anschwingen und außerdem in einer in der Querachse liegenden senkrechten Ebene. Letzteres wird durch die: Ausschnitte n' der feststehenden Kugelschale η ermöglicht.of the differential gear and also in a vertical plane lying in the transverse axis. The latter is made possible by the: sections n 'of the fixed spherical shell η .
Bei der Ausführungsform nach Fig. 2 treibt die Welle α durch Zahnräder b und c das ■ Achsenkreuz d des Differentialgetriebes an. Die Differentialräder f und g greifen in Kegelräder h und i der beiden in diesem Falle parallel gelagerten Antriebswellen k und m ein.In the embodiment according to FIG. 2, the shaft α drives the axles d of the differential gear through gears b and c. The differential gears f and g mesh with bevel gears h and i of the two drive shafts k and m, which in this case are mounted in parallel.
Auch hier ist die um den Mittelpunkt des ■ Achsenkreuzes d gekrümmte Kugelschale η fest mit dem Lager der Welle α verbunden, und die bewegliche Kugelschale 0 trägt die Lager des Achsenkreuzes d und die Lager der Antriebswellen k und m. Auch bei dieser Ausführungsform kann das Kugelgelenk in derselben Weise ausschwingen wie bei der vorstehend beschriebenen.Here, too, the spherical shell η curved around the center point of the axles d is firmly connected to the bearing of the shaft α , and the movable spherical shell 0 carries the bearings of the axles d and the bearings of the drive shafts k and m swing out in the same way as that described above.
Die beschriebene Konstruktion besitzt den bekannten Ausführungenjgegenüber auch den Vorteil, daß in die Antriebswelle ein Universalgelenk (Kardangelenk) nicht eingeschaltet zu werden braucht, da die Verbindung des Differentialgetriebes und des Antriebes mit der Kugelschale das Kardangelenk ersetzt. Einem Kardangelenk gegenüber besteht noch der Vorteil, daß der Neigungswinkel des einen Wellenteiles gegen den anderen nicht an ein bestirnmtes Maß gebunden ist.The construction described has the known designs compared to the Advantage that a universal joint (cardan joint) is not switched on in the drive shaft needs because the connection of the differential gear and the drive with the Ball socket replaces the universal joint. Compared to a cardan joint there is still the advantage that the angle of inclination of one part of the shaft against the other does not adhere to a certain Measure is bound.
