  • the electrical machine 12 is drive-connected to the connecting shaft 14 via a reinforcing planetary gear 17 and a spur gear stage 18.
  • This enables a particularly space-saving arrangement of the electrical machine 12, namely, viewed in longitudinal section or in the axial direction, on the side of the planetary differential gear 7 facing away from the input shaft 2, in axial overlap with the first output shaft or coaxially on the first output shaft 3.

This enables the illustrated coaxial arrangement of the electrical machine 12 on the first output shaft 3, which in turn leads to an extremely compact configuration of the transmission device 1.
  • the planet carrier 10 is connected in terms of drive technology to the second output shaft 4 via a gear stage 29, in particular a spur gear stage.

  • the gears 26, 27 and 28 and the gear stage 29 are, however, preferably arranged outside the gear housing 6.
  • the coaxial arrangement of the first output shaft 3 and the second output shaft 4 shown here as well as their axially parallel arrangement to the input shaft 2 enables the use of a conventional gear change transmission 5 so that no changes to the transmission housing 6 are necessary.

Abstract

L'invention concerne un dispositif de transmission (1) pour un véhicule à moteur, qui comporte un arbre d'entrée (2) pouvant coopérer avec un dispositif d'entraînement du véhicule à moteur ainsi qu'un premier arbre de sortie (3) et un deuxième arbre de sortie (4) et qui dispose d'une transmission à différentiel (7) de roue planétaire, par l'intermédiaire de laquelle l'arbre d'entrée (2) est couplé à au moins un des arbres de sortie (3, 4). La transmission à différentiel de roue planétaire comporte une couronne (8), une roue solaire (9) et un porte-satellites (10). Au moins une roue planétaire (11) est montée de manière à pouvoir tourner sur le porte-satellites (10) et s'engage à la fois avec la couronne (8) et la roue solaire (9). L'invention prévoit que la couronne (8) est couplée de manière solidaire en rotation à l'arbre d'entrée (2) et au premier arbre de sortie (3) et le porte-satellites (10) est couplé de manière solidaire en rotation au deuxième arbre de sortie (4). Le premier arbre de sortie (3) est disposé à distance parallèlement par rapport à l'axe de rotation, et la roue solaire (9) est couplée de manière solidaire en rotation ou peut être couplée de manière solidaire en rotation à un moteur (12) électrique.
