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.
