Hybrid Industrial Machine Powertrain

An industrial machine is provided that includes a hybrid powertrain. The hybrid powertrain includes a PTI/PTO (power-take-in/power-take-off) system that can passively decouple an internal combustion engine from other powertrain components. The hybrid powertrain allows the industrial machine to operate in power delivering modes, in which an internal combustion engine and/or an electric motor(s) are prime movers, a fully electric mode in which the electric motor(s) is the prime mover(s), and power generating modes, in which either the internal combustion engine or load inertia drives the electric motor(s) as an electrical power generator.
