  • the clutch 5 is closed and the clutch 21 occupies one of the two positions Sl or S2.
  • VKM Combustion engine driving
  • the brake 13 By closing the brake 13 and actuating the positive clutch 21 (synchronization) to the position S2 or S1, the first gear (FIG. 13) and second gear (FIG. 14) of the combustion engine driving VKM are engaged.
  • the brake 13 supports the planet carrier 9 against the housing G.
  • the clutch 5 is closed in each gear at the VKM. During the switching operation, however, the clutch 5 must be opened.
  • the switching elements brake 13, second clutch 14, clutch 5 and clutch 21 are operated in the modes of electric driving EM and combustion engine driving VKM in the second embodiment as follows, with "X" for activated and "0" for disabled stands: Operating mode gear shift elements
  • the present drive concept represents a combination of power-split and parallel system. Due to the fact that the drive takes place on the one hand via a ring gear 11, on the other hand via the sun gear 6, a parallel drive mode can be realized with both drive machines.
  • the internal combustion engine ICE can act on the sun gear 6, the electric machine 15 on a ring gear 11. Conversely, it is also possible to let the internal combustion engine ICE act on a ring gear and the electric machine 15 on a sun gear 6.

Abstract

L'invention concerne un engrenage planétaire (4) comportant : un pignon planétaire (6) monté de manière à pouvoir tourner autour d'un axe central (12) ; au moins un premier pignon satellite (7) se trouvant en prise par engrènement avec le pignon planétaire (6) et avec une première couronne (10) agencée coaxialement par rapport au pignon planétaire (6) ; et au moins un deuxième pignon satellite (8) se trouvant en prise par engrènement avec une deuxième couronne (11) agencée coaxialement par rapport au pignon planétaire (6). Le premier et le deuxième pignon satellite (7, 8) sont agencés de manière à pouvoir tourner sur un porte-satellites commun (9) monté de manière à pouvoir tourner autour de l'axe central (12), le premier pignon satellite (7) se trouvant en prise par engrènement avec le deuxième pignon satellite (8). L'engrenage planétaire (4) peut être bloqué par un deuxième embrayage (14) fonctionnant de préférence à l'état humide.
