Powertrain and method for a kinetic hybrid vehicle

摘要

A kinetic hybrid device and method for a vehicle may include a planetary gear system configured as a continuously variable transmission comprised of three or four ports. The kinetic hybrid device and method may include a flywheel connected to a first port of the system, a final drive connected to a second port of the system, and the variator for the flywheel connected to a third or fourth port of the system. The prime mover and/or other power sources may share a port with the flywheel, but do not share a port with the final drive.

主权项

1. A powertrain for a kinetic hybrid vehicle, comprising:
i. a planetary gear system configured as a continuously variable, compound power-split transmission comprising a first port, a second port, a third port, and a fourth port; ii. a flywheel connected to the first port of the planetary gear system through a first clutch; iii. a final drive of the vehicle, the final drive being connected to the second port of the planetary gear system; iv. a first motor/generator directly connected to the third port; v. a second motor/generator directly connected to the fourth port; and vi. an engine powered by internal combustion directly connected to the fourth port through a second clutch.
