  • Publication number: 20230339314
    Abstract: A transmission unit, a vehicle powertrain comprising the transmission unit and a vehicle are disclosed. The transmission unit comprises a first transmission shaft comprising a first gear wheel, and a second transmission shaft comprising a second gear wheel and a third gear wheel. The second gear wheel is arranged to cooperate with the first gear wheel. The transmission unit further comprises a third transmission shaft comprising a fourth gear wheel, the fourth gear wheel being arranged to cooperate with the third gear wheel. The third transmission shaft further comprises a fifth gear wheel arranged to be selectively connectable to the third transmission shaft for rotation therewith. The fifth gear wheel is arranged to cooperate with the second gear wheel. The transmission unit may be incorporated in a transmission arrangement further comprising a planetary gearbox unit.

  • Publication number: 20230341027
    Abstract: A transmission unit, a vehicle powertrain and a vehicle are provided. The transmission unit comprises a first transmission shaft forming an input shaft of the transmission unit, and a second transmission shaft comprising a first shaft portion and a second shaft portion. The first shaft portion is rotatably connected to the first transmission shaft via a first gear wheel pair. The transmission unit further comprises a third transmission shaft rotatably connectable to the first shaft portion via a second gear wheel pair and rotatably connectable to the second shaft portion via a third gear wheel pair. The second and third gear wheel pairs are arranged at a distance from each other in a direction parallel to the longitudinal axis of the second transmission shaft such that, when the transmission unit is arranged in the vehicle powertrain, an electrical machine may be arranged therebetween.
