Embodiment Construction
[0028] exist figure 1 1 shows in very schematic form a motor vehicle drive train 1 comprising an engine 2 , a starter 3 , a transmission 4 and an output shaft 5 . A so-called vibration damper 6 is arranged between the engine 2 and the starter 3 , here in the form of a friction clutch, by means of which vibration inhomogeneities of the engine 2 , here in the form of an internal combustion engine, can be damped.
[0029] The transmission device 4 is designed as a continuously variable power-split transmission, which has a planetary gear 7 designed as a negative planetary gear set on the transmission input side and a shifting gear 9 on the transmission output side, wherein the shifting gear The device 9 is arranged between the transmission 8 , here in the form of a belt transmission, and the transmission output 10 or the output shaft 5 of the vehicle drive train 1 .
[0030] The first shaft 11 of the planetary gear 7 configured as a ring gear is connected to the engine 2 via the...
