Estimating the term…
A drive train, wherein the drive train has a first electric machine (EMI) which can be operated in a motor or generator operating state, and a planetary gear mechanism (100) having a rotational-speed changing apparatus, wherein the rotational-speed changing apparatus is configured, in particular, as an internal gear (110) and/or as a planetary gear (114) and/or as a sun gear (112), wherein the planetary gear mechanism (100) has a drive side and a driven side, characterized in that the first electric machine (EMI) engages into the rotational-speed changing apparatus in a controlling manner in the motor or generator operating state, with the result that a step-up transmission ratio is formed in the planetary gear mechanism (100).
1-61. (canceled)
A drive train, the drive train having a first electric engine (EM1) and a second electric engine (EM2) which are both operable in a motor or generator operation mode, a combustion engine (VM) and planet gear mechanism (100) with a rotational speed changing apparatus, the rotation speed changing apparatus being designed more specifically as an internal gear (110) and/or as a planetary gear (114) and/or as a sun gear (112), and the planet gear mechanism (100) having a drive side and a driven side, the combustion engine being flanged on the drive side and the second electric engine (EM2) being located on the drive side and the second electric engine (EM2) being flanged to the shaft (130) on the driven side, so that a torque can be applied to the shaft (130) by the second electric engine (EM2) or applied by the shaft to the second electric engine (EM2) in a generator operation mode, wherein the first electric engine (EM1) steeredly intervenes in the rotational speed changing apparatus, so that a transmission ratio can be almost continuously adjusted.
