Drive system for a hybrid vehicle

A drive system for a hybrid vehicle, comprising:

• an internal combustion engine;
• an electric motor;
• and
• a clutch device comprising a frictional locking element and a positive locking element connected in parallel with respect to the frictional locking element,
• wherein the clutch device is configured to couple the internal combustion engine into the drive system and to be switched into at least the following states:
• a) open positive locking element and closed frictional locking element when starting and/or synchronization of the internal combustion engine,
• b) closed positive locking element and closed frictional locking element or closed positive locking element and open frictional locking element when the internal combustion engine is running and synchronized such that an internal combustion engine drive output action is generated, and
• c) open positive locking element and open frictional locking element when the internal combustion engine is stopped such that purely electric motor drive of the vehicle is provided,
• wherein the frictional locking element is formed with a first rotary clutch element and with a second rotary clutch element which are arranged coaxially with respect to one another and which are provided so as to be displaceable toward one another and away from one another, wherein the first rotary clutch element has an outer cone and the second rotary clutch element has an inner cone, which outer cone and inner cone are placed in contact with one another to transmit torque.
