Axle Assembly For Hybrid Electric Vehicle

摘要

A hybrid electric vehicle axle includes two separate pinion gears meshing with a single beveled ring gear. One pinion gear conveys power from the internal combustion powertrain while the other pinion conveys power from an electric motor. Power from the electric motor is conditioned by a two-speed gearbox between the electric motor and the second pinion gear. The gearbox may utilize layshaft gearing or planetary gearing such as a Ravgneaux gear set.
