Problems solved by technology
In many applications, the resulting problem is that the installation space in the engine compartment is limited, since for example the engine compartment is of conventional design and thus suitable for only one conventional internal combustion engine and one alternator (the generator alone is used for the engine torque absorb)
Therefore, complex measures had to be taken to reduce the space required by the unit

Embodiment Construction
[0147] exist figure 1 , a motor vehicle 77 is schematically shown from above, wherein the structure of the hybrid powertrain 1 with the combustion power section 2 , the electric power section 3 and the output 60 can be seen in a cutout at the rear of the vehicle. The illustrated hybrid powertrain 1 only shows the functional interconnection of the components of the hybrid powertrain 1 and does not provide any information about the actual structural nesting of the components. An advantageous embodiment of a possible structural nesting of the components of the hybrid powertrain 1 is in figure 2 , and in this regard reference is made to the description therein.
[0148] The output 60 is configured to transmit torque about an output axis 85 to the left drive wheel 78 by means of the left output shaft 4 and to transmit torque about this output axis to the right drive wheel 79 by means of the right output shaft 5 . Here, the designations left and right are chosen for the usual dir...

The invention relates to a hybrid powertrain (1) with a combustion power section (2) and an electric power section (3). Both power sections (2, 3) are designed to provide a torque to at least one output shaft (4, 5) as required, wherein the hybrid powertrain (1) additionally comprises an output transmission (6) torque-transmittingly connected to the at least one output shaft (4, 5), and the electric power section (3) comprises at least one electric machine (7) with a rotor shaft (8). The combustion power section (2) has at least the following components: an internal combustion engine (9) with a combustion shaft (10); a generator (11) with a generator shaft (12); and a continuously variable belt transmission (13), said continuously variable belt transmission (13) comprising a combustion-side cone pulley pair (14) and an output-side cone pulley pair (15) which are variably torque-transmittingly connected together by a belt (16) and each of which comprises an axially movable pulley (17, 18). The hybrid powertrain (1) is primarily characterized in that the combustion-side movable pulley (17) is arranged on the generator shaft side. The invention additionally relates to an assembly method for a hybrid powertrain (1). Here, a hybrid powertrain is proposed in a compact configuration which can be introduced into a motor vehicle and can be easily installed.
