Abstract
A hybrid power train system for a tractor scraper is provided. The hybrid power train system may include a primary power source coupled to a first set of traction devices, a generator coupled to the primary power source, a first electric motor coupled to a second set of traction devices, an inverter circuit coupled to the generator and the first electric motor, an energy storage device coupled to the inverter circuit, and a controller operatively coupled to the inverter circuit. The controller may be configured to engage a first operation mode enabling electrical energy, supplied by the generator and the first electric motor, to be stored in the energy storage device, and engage a second operation mode enabling electrical energy, stored in the energy storage device, to be supplied to the first electric motor to drive the second set of traction devices.
