Abstract
A powertrain for a machine may include a flywheel and a drivetrain having multiple configurations to permit the flywheel to be mechanically connected both upstream and downstream of a transmission. A bypass clutch may be used to selectively couple the flywheel directly to the engine, while a flywheel clutch may be used to selectively couple the flywheel directly to a lower powertrain. In both upsteam and downstream modes of operation, the transmission is bypassed to increase flywheel energy storage and use, as well as expanding the functionality of the flywheel.
