Abstract
A hybrid vehicle may be a series hybrid or a parallel hybrid vehicle. One embodiment of a parallel hybrid vehicle includes an engine, a transmission coupled to the engine, a front drive coupled to the transmission through a prop shaft, a rear drive coupled to the transmission, a traction motor drivingly coupled to the prop shaft, and a battery to operate the traction motor.
Claims13
A parallel hybrid power train for a vehicle, comprising:
- an engine;
- an electric motor/generator;
- a transmission comprising:
- an input shaft, wherein the engine is coupled to the input shaft;
- and
- a second shaft drivingly coupled to the input shaft, the electric motor/generator coupled to the second shaft;
- a first power transmission component operably coupled to the second shaft;
- a third shaft offset from the input shaft and the second shaft;
- a second power transmission component operably coupled to the third shaft;
- a clutch operably coupled to the third shaft, the clutch operable to selectively couple the second power transmission component with the first power transmission component of the second shaft, and wherein the second shaft is coupled to the input shaft independent of the third shaft;
- and
- a final drive assembly operably coupled to the engine and the electric motor/generator via the transmission, the final drive assembly being provided for driving ground engaging members of a vehicle.
