Abstract
A drive system (1) for a motor vehicle has a double clutch transmission (2), with two component transmissions (3, 4), a double clutch (5) and an output shaft (6). An internal combustion engine (7) optionally can be connected operatively to one of the component transmissions (3, 4) via the double clutch (5) to drive the output shaft (6). A gear drive (8) is arranged rotatably on the output shaft (6). An electric machine (9) can be connected operatively via the gear drive (8) to at least one fixed gear (16, 17, 21) of one of the component transmissions (3, 4) to drive the output shaft (6) and/or to recover kinetic energy from the drive system (1).
Claims14
A drive system for a motor vehicle, having:
- a double clutch transmission with first and second component transmissions, a double clutch and an output shaft;
- an internal combustion engine operatively connectable to one of the component transmissions via the double clutch to drive the output shaft;
- a gear drive rotatably arranged on the output shaft (6);
- and
- an electric machine operatively connectable via the gear drive to at least one fixed gear of one of the component transmissions to drive the output shaft or to recover kinetic energy from the drive system.
A method for operating a drive system that has a double clutch transmission with two component transmissions, a double clutch and an output shaft, comprising:
- optionally operatively connecting an internal combustion engine to one of the component transmissions via the double clutch to drive the output shaft;
- and
- operatively connecting an electric machine to at least one fixed gear of one of the component transmissions via a gear drive that is arranged rotatably on the output shaft to drive the output shaft or to recover kinetic energy from the drive system.
