Problems solved by technology

The disadvantage of parallel hybrids is that the mechanical consumption is very high and the possibility of operating the internal combustion engine in the desired efficiency range is greatly limited, since the internal combustion engine is always or almost always also used together to provide the typical high dynamic power required

Embodiment Construction

[0027] exist figure 1 An exemplary construction of the drive device 1 according to the invention can be seen in the description of . The drive device 1 can be used for various drive purposes. For example, the drive device can be used to drive a vehicle (not shown in detail), in particular a commercial vehicle or a passenger car. The drive device 1 comprises an internal combustion engine 2 , which is typically designed as a diesel engine in the above-mentioned example of a commercial vehicle, as well as a first electric machine 3 and a second electric machine 4 . Furthermore, in the exemplary embodiment shown here, the drive device 1 also has a transmission 5 . The internal combustion engine 2 is connected to the rotor 7 of the first electric machine 3 via a per se known and usual torsional vibration damper 6 , which can be designed as a vibration damper and / or damper. The first electric machine 3 is designed as a transverse flux machine, so that a rotor 7 which moves, for e...

Abstract

A drive device has an internal combustion engine, a first electrical machine, and a second electrical machine. The first electrical machine is at least indirectly connectable to the internal combustion engine. In addition, the drive device has an output which is at least indirectly connected to an output shaft. According to the invention, a switching device is provided, using which, in a first state, the internal combustion or the first electrical machine is connectable to the output shaft or, in a second state, the second electrical machine is connectable to the output shaft.

Description

technical field [0001] The invention relates to a drive device according to the type defined in detail in the preamble of claim 1 . Furthermore, the invention relates to the use of such a drive. Background technique [0002] Drives with an internal combustion engine and an electric machine or electric machines combined with one another, for example for driving a vehicle, are known from the general prior art. Such drives are also referred to as hybrid drives. For hybrid drives, a distinction is made between two basic technical solutions. [0003] A first technical solution is a so-called series hybrid drive, which is designed such that the internal combustion engine drives a first electric machine as a generator and thus generates electricity. The current generated in this way is then supplied to the second electric machine via the power electronics and, if appropriate, via the buffer memory. This results in a structure in which there is no mechanical coupling between the...
