Title
(DE) ANTRIEBSACHSE MIT VARIABLER MOMENTENVERTEILUNG FÜR EIN KRAFFTFAHRZEUG
(EN) DRIVE AXLE COMPRISING A VARIABLE TORQUE DISTRIBUTION FOR A MOTOR VEHICLE
(FR) ESSIEU MOTEUR A REPARTITION DE COUPLE VARIABLE POUR UN VEHICULE AUTOMOBILE
Abstract
(DE)
Eine Antriebsachse mit variabler Momentenverteilung für ein Kraftfahrzeug enthält eine Mittenwelle (34) und je eine Achsantriebswelle, wobei eine Primärantriebswelle (33) mit der Mittenwelle (34) antriebsverbunden ist und ein Sekundärantrieb (8, 9) vorgeshen ist. Um fahrdynamisch erwünschte Steuereingriffe vornehmen u nd einen Hybridbetrieb üben zu können, ist das Überlagerungsgetriebe (10, 11) ein hohlradloses Stirnradplanetengetriebe mit zwei Sonnenrädern (41, 42), deren erstes Sonnenrad (41) mit der Mittenwelle (34) und deren zweites Sonnenrad (42) jeweils mit einer Achsantriebswelle (43) antriebsverbunden ist, und dessen Planetenträger (45) mit dem Sekundärantrieb (8, 9) antriebsverbunden ist.
(EN)
The invention relates to a drive axle comprising a variable torque distribution for a motor vehicle. Said axle comprises a central shaft (34) and a respective drive shaft, a primary drive shaft (33) being connected to the central shaft (34) in a driven manner, and a secondary drive (8, 9). The aim of the invention is to permit interventions required for the vehicle dynamics and a hybrid operation. To achieve this, the overlaid gear (10, 11) is a spur wheel planet gear without a rotor wheel, comprising two sun gears (41, 42), the first sun gear (41) being connected in a driven manner to the central shaft (34) and the second sun gear (42) being connected in a driven manner to a respective axle drive shaft (43). The planet carrier (45) is connected to the secondary drive (8, 9) in a driven manner.

L'invention concerne un essieu moteur à répartition de couple variable pour un véhicule automobile, qui comprend un arbre central (34) et respectivement un arbre d'entraînement d'essieu, un arbre d'entraînement primaire (33) étant relié par entraînement à l'arbre central (34) et un entraînement secondaire (8, 9) étant prévu. L'invention vise à permettre de procéder à des interventions de commande désirées pour la dynamique de conduite et de réaliser un fonctionnement hybride. A cet effet, la boîte de superposition (10, 11) est un engrenage planétaire à pignons droits exempt de couronne et pourvu de deux roues planétaires (41, 42) dont la première (41) est reliée par entraînement à l'arbre central (34) et dont la deuxième (42) est reliée par entraînement à un arbre d'entraînement d'essieu correspondant (43), les porte-satellites (45) de l'engrenage étant reliés par entraînement à l'entraînement secondaire (8, 9).
