Abstract
An electric driveline system is provided. The electric driveline system includes a first electric machine and a second electric machine mechanically coupled to a transmission and a power take-off (PTO) assembly coupled to the first electric machine. The PTO assembly includes a first clutch coupled to a PTO gearset and designed to selectively disconnect a PTO from the first electric machine and the PTO gearset is mechanically coupled to the first electric machine.
Claims15
An electric driveline system, comprising:
- a first electric machine and a second electric machine mechanically coupled to a transmission;
- and
- a power take-off (PTO) assembly coupled to the first electric machine and comprising:
- a first clutch coupled to a PTO gearset and designed to selectively disconnect a PTO from the first electric machine;
- a second clutch designed to selectively disconnect the first electric machine from the transmission, wherein the second clutch is a friction clutch;
- and
- a synchronizer arranged coaxial with the second clutch,
- wherein the PTO gearset is mechanically coupled to the first electric machine;
- and
- wherein the second electric machine includes an output shaft, the output shaft only directly coupled to the second electric machine and a first gear, the first gear configured to be in meshing engagement with a transmission gear of the transmission to provide the mechanical coupling between the second electric machine and the transmission.
