Abstract
In a hybrid transmission, a traction motor is mounted between a dry clutch module and a manual gearbox. A slave cylinder is mounted within the rotor of the traction motor to reduce axial length. The rotor is fixedly coupled to an engine crankshaft. The stator may be cooled by circulating engine coolant through the housing. The stator and the rotor may be cooled by spraying transmission fluid into a sealed motor cavity.
Claims18
A hybrid transmission comprising:
- a housing having a bulkhead;
- a shiftable gearbox having an input shaft extending through the bulkhead;
- a flywheel adapted for fixation to an engine crankshaft;
- a clutch configured to selectively couple the flywheel to the input shaft;
- and
- an electric machine mounted between the clutch and the bulkhead, the electric machine having a stator fixed to the housing and a rotor fixedly coupled to the flywheel.
A hybrid vehicle comprising:
- a housing having a bulkhead and fixed to an engine block;
- a shiftable gearbox having an input shaft extending through the bulkhead;
- a flywheel fixed to an engine crankshaft;
- a clutch configured to selectively couple the flywheel to the input shaft;
- and
- an electric machine mounted between the clutch and the bulkhead, the electric machine having a stator fixed to the housing and a rotor fixedly coupled to the flywheel.
A method of assembling a hybrid vehicle comprising:
- installing a stator and rotor into a transmission front housing, the rotor having a rotor hub;
- fixing a clutch module to an engine crankshaft, the clutch module having a flywheel;
- and
- after attaching the transmission front housing to an engine block, securing the flywheel to the rotor hub.
