Abstract
A hybrid drivetrain (100) is provided. The hybrid drivetrain comprises a power source (102), a first motor generator assembly (104), and an electric axle drive unit (106). The first motor generator assembly includes a primary clutch (114) for drivingly engaging the power source with a first motor-generator (116). The electric axle drive unit comprises at least a second motor generator (140) drivingly engaged with the first motor generator and a pair of wheel assemblies (112). The power source, the first motor generator assembly, and the electric axle drive unit facilitate operating the hybrid drivetrain as a series-parallel hybrid drivetrain in a plurality of operating modes. The hybrid drivetrain meets the exacting needs of commercial vehicles while providing fuel efficiency improvements for vehicles incorporating the hybrid drivetrain.
