Abstract: A drivetrain has a first speed path and a third speed path. The first speed path includes a one-way clutch that allows power transmission from the drive shaft toward the driven shaft but prevents power transmission in the opposite direction. The third speed path includes a one-way clutch that allows power transmission from the driven shaft toward the drive shaft but prevents power transmission in the opposite direction. The third speed path further includes a shift clutch member. This can provide a drivetrain capable of performing regenerative control to derive electricity appropriately from an electric motor and also capable of shifting gears smoothly.

Abstract: The variable speed transmission uses multiple fluid couplings to provide a sturdy, durable variable output ratio transmission by using hydraulic fluid to vary the output. Each fluid coupling has an independent output shaft driven by the respective fluid coupling turbine. Output shafts drive alternate gears (i.e., first and third at a first fluid coupling and second and fourth at a second fluid coupling). This configuration alternates gear shifts between the fluid couplings allowing the next gear up or down to be engaged before disengaging the current gear, for uninterrupted gear changes in both up and down shifting. A fifth gear would be driven by a gear connected to the fluid coupling input shafts. Gears could be engaged with hydraulic clutches or syncromesh gears. This combined with variable slip fluid couplings allows for better torque and control.
