  • the invention relates to a hybrid transmission, a hybrid drive arrangement with the hybrid transmission and a method for operating the hybrid drive arrangement.
  • Hybrid drive units are known from the prior art, which comprise two electrical machines and at least one coupling device. There is one between an electrical machine and an output element.
  • Known hybrid drive systems comprise two electrical machines and a transmission, a coupling device being arranged between one of the electrical machines and the transmission in order to couple or uncouple this electrical machine.
  • the transmission is often a
  • Automatic gearbox or dual clutch gearbox The choice of gear can also depend on the design of the electrical machine. For example, with a correspondingly high output, it is one for driving the motor vehicle
  • Drive arrangements are also known, which comprise two electrical machines, a gear unit, a disconnect clutch as well as further coupling devices and an internal combustion engine, in order to implement a wide variety of driving modes for a motor vehicle.
  • the two electrical machines are for different performances.
  • the electric machine with higher power is used as a drive unit.
  • the electrical machine with lower power has a negligible drag torque and is accordingly preferably used for the recuperation of electrical energy.
  • the present invention is based on the object of providing a hybrid transmission, a hybrid drive arrangement and a method for operating a hybrid drive arrangement, with which the most varied operating or driving states of the hybrid transmission can be achieved in a simple, inexpensive and space-saving manner or the hybrid drive arrangement equipped motor vehicles can be realized.
  • the invention in a first aspect, relates to a hybrid transmission, comprising a connection device for coupling to an internal combustion engine Separating clutch, a first electrical machine, a first coupling device and an output device of the hybrid transmission, which are connected to one another in series.
  • the connection device is mechanically coupled to the input side of the clutch and the output side of the clutch is coupled to a rotor of the first electrical machine.
  • the machine is coupled to the input side of the first clutch device and the output side of the first clutch device is coupled to the output device of the hybrid transmission.
  • the output side of the first clutch device is coupled to the output device of the hybrid transmission.
  • Hybrid gearbox just arranged an electrical machine.
  • a differential gear can be arranged on the output device, or the output device can be formed by this output device.
  • Coupling devices thus define a first torque transmission path between the connection device and the output device.
  • the first electrical machine provided according to the invention has a significantly lower nominal power and consequently makes no significant contribution to the drive power of a motor vehicle equipped with the hybrid transmission.
  • the hybrid transmission further has a second clutch device, which in one of the disconnect clutch, the first electrical machine and the first
