  • the present invention relates to a hybrid drive arrangement for a motor vehicle comprising at least two drive units, namely at least one internal combustion engine and an electric machine, a double clutch arrangement which has a first friction clutch and a second friction clutch, the friction clutches having a common input element coupled to the internal combustion engine and one output element each have a transmission arrangement which has a first partial transmission and a second partial transmission, the output element of the first friction clutch being connected to an input of the first partial transmission and the output element of the second friction clutch being connected to an input of the second partial transmission and a housing in which at least the double clutch arrangement (4) is arranged.
  • a hybrid motor vehicle In vehicle technology, a hybrid motor vehicle is generally understood to mean a motor vehicle that has a combination of an internal combustion engine and an electric drive system. These two drives can be combined in a wide variety of ways. Depending on how the internal combustion engine, the electric machine and the transmission of the motor vehicle are arranged, a basic distinction is made between serial, parallel and power-split hybrid drive trains. Furthermore, mixed forms of these three basic structures are often used, which have the advantages of combine respective structures.
  • the most common form in hybrid vehicle technology is the parallel hybrid powertrain arrangement, in which the electrical path runs parallel to the combustion engine path and the power of both systems is mechanically superimposed to drive the vehicle. In this case, the electric machine can be arranged at different points in the drive train, resulting in specific advantages and disadvantages in each case.
  • P2 arrangements are often implemented.
  • the electric machine is not installed directly on the internal combustion engine, but is located at the transmission input with a clutch in between, which enables the internal combustion engine to be decoupled from the rest of the drive train if necessary.
  • "Electric driving” and “recuperation” can be operated more efficiently, namely without sacrificing the drag torque of the internal combustion engine.
  • other functions such as “electric starting” and “stationary charging” can also be implemented.
  • connection of the electrical machine on the transmission input side is either directly to a clutch basket of a clutch via gearing or a chain, whereby the clutch must transmit the resulting radial and axial forces and must be designed accordingly in terms of strength and function, or to at least one input shaft of the transmission, which requires an increase in the axial length of the transmission.
