    The invention relates to a drive unit for a hybrid vehicle, comprising an internal combustion engine and a hybrid transmission connected to the internal combustion engine with at least one electric machine, wherein in particular the drive shaft of the internal combustion engine is drive-connected via a separating clutch with a main shaft of the hybrid transmission.
    It is known to connect internal combustion engines directly with hybrid transmissions, wherein the crankshaft is connected via a separating clutch with the main shaft of the hybrid transmission. «» 4 · *
    It is also known to drive auxiliary equipment from the transmission side, because there are * * in hybrid transmissions operating conditions in which the internal combustion engine is not * .. * runs *, but still a drive of the auxiliary equipment is needed. This drive is usually carried out via an additional shaft of the transmission. This haf ... r. the disadvantage that additional space must be provided, and *: *: Thus, the drive train takes up relatively much space. Another disadvantage·. # ί 4 «is that the additional shaft increases the number of parts and the weight of the drive train.
    The object of the invention is to avoid these disadvantages and to reduce weight, number of parts and space in a drive unit of the type mentioned.
    According to the invention, this is achieved in that at least one auxiliary unit is drive-connected directly or indirectly to a main shaft of the hybrid transmission from an end face of the hybrid transmission facing away from the internal combustion engine.
    Preferably, it is provided that the main shaft of the hybrid transmission is arranged coaxially with the drive shaft of the internal combustion engine, wherein preferably the main shaft of the hybrid transmission is drive-connected via a separating clutch with the internal combustion engine.
    A drive pulley for a traction means, preferably a toothed belt or V-belt, can be arranged on the main shaft in the region of the end face of the hybrid transmission facing away from the internal combustion engine, wherein at least one auxiliary unit is drive-connected to the traction means. 2
    In a particularly compact embodiment of the invention, it is provided that a separating clutch is integrated into the drive pulley. With the separating clutch, the drive connection between the drive shaft of the internal combustion engine and the main shaft of the hybrid transmission can be herdgestellt.
    The auxiliary units may be, for example, a compressor of an air conditioning system of the vehicle and / or a coolant pump for cooling the electric machine.
    In order to maintain their cooling in the case of a standstill of the electric machine, it is particularly advantageous if in the coolant pump a .... electric motor is integrated, which only the coolant pump in the alternative;.;; drives. ** · ;; • * • ·
    The hybrid transmission preferably has at least one planetary gear whose f *:
    Sun gear with the main shaft via the separating clutch is drive-connected,:: * * wherein at least one component of the planetary gear, preferably at least one ring gear of the planetary gear, at least one electric machine acts.
    The invention will be explained in more detail below with reference to the invention. 1 shows a drive unit according to the invention in an oblique view, Fig. 2, this drive unit is a longitudinal section, Fig. 3 and 4, the hybrid transmission of the drive unit in longitudinal section.
    FIGS. 1 and 2 show the drive unit 1 according to the invention for a hybrid vehicle, which has an internal combustion engine ICE and a hybrid transmission HT.
    Fig. 3 shows schematically the hybrid transmission HT with a driven by the drive shaft 25 of the internal combustion engine ICE first shaft 2 and a driven second shaft 3, wherein between the first and second shaft 2, 3, a planetary gear 4 is arranged.
    The internal combustion engine ICE is in the exemplary embodiment a reciprocating engine. Of course, however, other internal combustion engines, such as a rotary piston engine can be used. 3
    The planetary gear 4 has a fixedly connected to a main shaft 20 sun gear 6, which main shaft with the first shaft 2 via an example dry first clutch 5 is connectable. Furthermore, the planetary gear 4 has first planetary gears 7 and second planetary gears 8, which are rotatably arranged on a planet carrier 9, as well as a first ring gear 10 and a second ring gear 11. The main shaft 20 with the sun gear 6, the planet carrier 9 and the two ring gears 10, 11 are rotatably mounted about a central axis 12. The hollow main shaft 20 is arranged coaxially with the first shaft 2.
    The first ring gear 10 in this case has a smaller inner diameter di, as d ^ s · * second ring gear 11, whose diameter is denoted by d2. The first *
    Planet gears 7, 8 are in meshing engagement with the sun gear 6 and the inner ring gear 10, respectively. The second planetary gears 7, 8 in turn are in each case connected to the first planet gears 7 and the outer second ring gear 11: "meshing engagement. · ,.
    The first ring gear 10 can be held by a brake 13. Via a second clutch 14, a rotary connection of the second ring gear 11 with the planet carrier 9 can be produced. The brake 13 and the second clutch 14 are preferably made wet.
    The second ring gear 11 can further be driven by an electric machine 15. In the example, for the rotor 16 of the electric machine 15 is fixedly connected to the second ring gear 11 or carried out integrally therewith. This electric machine 15 takes over the function of the starter and the alternator, as well as the drive of the compressor of an air conditioner when the internal combustion engine ICM is turned off.
    The planet carrier 9 is fixedly connected to the hollow shaft 17 which surrounds the first shaft 2 designed as a torsion shaft and which is drive-connected via a downstream intermediate transmission stage 18 and a final gear stage 19 or a transfer case with drive wheels.
    Fig. 4 shows the hybrid transmission HT in a structural design in longitudinal section. As can be clearly seen, the separating clutch 5 is at the same time designed as a drive pulley 21 for a traction means 22, for example for a poly-V belt 4. This arranged in the region of one of the internal combustion engine ICE end face 26 of the hybrid transmission HT traction means 22 serves to drive auxiliary units 23, 24, such as a coolant pump 23 and a compressor 24 for a not shown air conditioning. The transmission-side coolant pump 23 for the cooling of the electric machine 11 is driven in the traction drive of the compressor 24 in a triangle. Characterized in that the drive takes place directly through the main shaft 20 of the hybrid transmission HT, separate intermediate shafts for driving the auxiliary units 23, 24 omitted. Furthermore, can be integrated into the coolant pump 23, a small electric motor. In the case of the stationary electric machine 15, the cooling can be maintained by this integrated into the coolant pump 23 electric motor. ,
    The combination of internal combustion engine ICE and electric machine 15 in the hybrid transmission HT, a continuous drive of the auxiliary units 23, 24 even when the internal combustion engine ICE is possible. ϊ
