    The invention relates to a drive train for a hybrid vehicle, comprising an internal combustion engine, at least one electric machine, with a first planetary gear and a second planetary gear between a drive input shaft connected to the output shaft of the internal combustion engine and a transmission output shaft, wherein each planetary gear has the components sun gear, web and ring gear , and wherein the transmission input shaft is drive-connected to a first component of the first planetary gear, and the first planetary gear and the second planetary gear in the drive train are arranged in series behind each other and drivingly connected to each other via a same for both planetary gear second component, and wherein a third component at least one of two planetary gear can be connected to a braking device.
    Drive trains for series hybrid vehicles with an internal combustion engine and at least one electric machine are known from the publications US 6,026,921 A, DE 10 229 535 A1 and US 7,347,803 A. In such known as Vollhybridsysteme drive trains, the vehicle can be operated either alone by the electric motor without the assistance of the internal combustion engine. At a certain operating point, the internal combustion engine is connected, whereby the drive is effected by combining the internal combustion engine with the electric motor. For connecting and disconnecting the internal combustion engine with or from the rest of the drive train a clutch is required. The disadvantage is that additional space must be made available for the clutch.
    Furthermore, hybrid powertrains are known with planetary gear sets, which are used as a power-split transmission, wherein an electric machine and an internal combustion engine to various components of the planetary gear attack and wherein the output is via a further component of the planetary gear. Such an arrangement is known for example from DE 10 2007 054 361 Al. The disadvantage is that in such an arrangement, the electric machine must constantly provide torque to transmit drive torque of the internal combustion engine in the drive train.
    The object of the invention is to provide a simple and space-saving drive train for a hybrid vehicle. - 2 -
    According to the invention this is achieved in that the first and the second planetary gear are constructed identical, that the braking device acts on a third component of the first planetary gear, preferably a like third component of the second planetary gear is fixed to the housing, and that to the first component of the first Planetary gear same name first component of the second planetary gear is drivingly connected to the transmission output shaft.
    The electric machine can be drive-connected to the first or second component of the second planetary gear.
    In a very simple and compact embodiment, it is provided that the second component is formed in each case by the ring gear of the planetary gear. For rigid drive connection while the ring gears of the first and second planetary gear can be integrally formed integrally.
    It when the first component is formed by the sun gear and the third component through the web of the planetary gear is particularly advantageous. Alternatively, it is also possible that the first component is formed by the web and the third component by the sun gear of the planetary gear.
    All variants have in common that the drive train is designed without switchable shaft coupling, so that the internal combustion engine is constantly and fixed to the first component of the first planetary gear and the transmission output shaft is constantly and fixedly connected to the same first component of the second planetary gear.
    The fact that switchable shaft couplings in the drive train between the engine and the output shaft of the vehicle is completely eliminated, on the one hand space and components can be saved, on the other hand results in a very easy control for switching between the two prime movers.
    The invention will be explained in more detail below with reference to FIGS.
    1 shows a drive train according to the invention in a first embodiment, FIG. 2 shows a drive train according to the invention in a second embodiment and FIG. 3 shows a drive train according to the invention in a third embodiment.
    FIGS. 1 to 3 show a drive train for a hybrid vehicle with an internal combustion engine 1, an electric machine 3, a first planetary gear 4 and a second planetary gearbox 5. The remaining gearbox-driven powertrain including differential and drive wheels is denoted by reference numeral 2 indicated. The output shaft 10 of the internal combustion engine 1 is directly connected to the transmission input shaft 8 and this in turn directly connected to a first component Kll of the first planetary gear 4. A first-named component K21 of the second planetary gear 5 is connected directly to the output-side drive train 2 via the transmission output shaft 9.
    Each of the two planetary gear 4, 5 has a sun gear SOI, S02, a web ST1, ST2 with planetary gears PLI, PL2 and a ring gear Hl, H2.
    As will be explained below, the first component K11, K21 can be either the web ST1, ST2, or the sun gear SO1, SO2, wherein it is essential that the first component K11, K21 in each embodiment be replaced by the same part. So either sun gear or bridge - is formed. The same name in this context means that the first component in the first planetary gear 4 and the second planetary gear 5 is formed by the same component.
    A second component K12 of the first planetary gear 4 is rigidly drive-connected to a second-named component K22 of the second planetary gear 5. In all embodiments shown here, the second component K12, K22 by ring gears Hl, H2 of the two planetary gear 4, 5 is formed, wherein the ring gears Hl, H2 both planetary gear advantageously in one piece and thus may be formed as a common Hohlradeinheit H.
    A third component K13 of the first planetary gear 4 can be braked via a braking device 6. The eponymous third component K23 of the second planetary gear 5 is held firmly, that is firmly fixed to the housing 7 of the planetary gear 5. Analogous to the first component, the third component K13, K23 can be either the sun gear SOI, SO2 or the bridge ST1, ST2, wherein it is also essential here that the third component K13, K23 in each case by the same part - ie either bridge or sun gear - is formed. Again, the same name means that the third component in the first planetary gear 4 and the second planetary gear 5 is formed by the same component.
    First and second planetary gear 4, 5 may advantageously be arranged in a common housing 7.
    In Fig. 1, the first components Kll, K21 of the first and second planetary gear 4, 5 are formed by the webs ST1, ST2. The sun gears SOI, - 4 - S02 of the two planetary gear 4, 5 form the third components K13, K23. The electric machine 3 is connected directly to the Getriebeabtriebsweile 9.
    Fig. 3 differs from the embodiment shown in Fig. 1 in that the electric machine 3 acts directly on the common ring gear H. The remainder of the arrangement corresponds to that of FIG. 1.
    The embodiment variant shown in FIG. 2 differs from the embodiment shown in FIG. 1 in that the first components K11, K21 are each separated by the sun gears SOI, SO2 of the planetary gears 4, 5 and the third components K13, K23 through the webs ST1 , ST2 of the two planetary gear 4, 5 are formed. Thus, the internal combustion engine 1 is connected via the transmission input shaft 8 directly to the sun gear SOI of the first planetary gear 4. Furthermore, the transmission output shaft 9 is directly connected to the sun gear S02 of the second planetary gear 5. The braking device 6 acts on the web ST1 of the first planetary gear 4.
    By actuating the braking device 6, which may be formed for example by a brake band, the torque of the internal combustion engine 1 can be continuously switched on or off. Due to the identical design planetary gear 4, 5 a very cost-effective, compact drive train arrangement is possible, with switchable shaft couplings can be completely eliminated.
