| 摘要 |
The invention relates to a hybrid drive train (1) of a vehicle, comprising a drive system having an internal combustion engine (3) and a first electric supplementary drive unit (8) as well as a transmission arranged downstream of the drive system for controllably distributing the rotational speed and the torque of the drive power of the drive system to an output shaft, wherein the transmission includes a first and a second gearbox unit (11, 21) and a planetary gearing (5) having four components, namely a planet element, a planet carrier and two gears engaging with the planet element, and wherein further the internal combustion engine (3) can be coupled to the output shaft via a direct power path, by bypassing the first electric supplementary drive unit (8), through several mechanical gears of the first and/or second gearbox, wherein for this the first gearbox includes a first coupling means (12) and the second gearbox (21) includes a second coupling means (20). |
