<p>Drive unit for a hybrid vehicle, whereas the drive unit comprises a drive assembly (3) with an internal combustion engine (1) and an electric motor (2) and a transmission (5) featuring several sub-transmissions (6, 7) shifting between the drive assembly (3) and an output (4), whereas, through a planetary transmission (10), the electric motor (2) is coupled to an input shaft (8) of a first sub-transmission (6) and an input shaft (9) of a second sub-transmission (7) shifted in parallel to the first sub-transmission (6), whereas, through a separating clutch (11), the internal combustion engine (1) is able to be coupled to the input shaft (8) of the first sub-transmission (6) and, if the separating clutch (11) is locked, is coupled to the same element of the planetary transmission (10) together with the input shaft (8) of the first sub-transmission (6), whereas a bypass shift element (12) works together with the planetary transmission (10) in such a manner that, with a locked bypass shift element (12), a torque-proof connection between the electric motor (2), the input shaft (8) of the first sub-transmission (6) and the input shaft (9) of the second sub-transmission (7) and thus a mandatory equality of rotational speed between the same, exist, while, with an open bypass shift element (12), this torque-proof connection between the electric motor (2) and the two input shafts (8, 9) of the two sub-transmissions (6, 7), and thus the mandatory equality of rotational speed, do not exist, whereas the separating clutch (11) is formed as a frictional-locking or positive-locking separating clutch, and whereas the bypass shift element (12) is formed as a frictional-locking bypass shift element (12).</p> |
