Two speed gear reducer with power take off for electric drive module

An electric drive module (EDM) for an electrified vehicle, the EDM having a housing, an electric motor and a two-speed gearbox assembly, the two-speed gearbox assembly comprising:

• one compound planetary gear set including a sun gear, a ring gear and a single planetary carrier having compound planetary gears each including a first gear in meshing engagement with the sun gear and a second gear in meshing engagement with the ring gear;
• an input shaft connected to the sun gear and coupled to an output of the electric motor;
• a power take off (PTO) driven by the input shaft;
• a first torque transfer device comprising a controllable clutch that selectively couples the carrier to the input shaft;
• a second torque transfer device configured for selectively coupling the carrier to the housing;
• wherein the ring gear is a fixed dedicated output of the two-speed gearbox assembly, which is coupled to a final drive of the electrified vehicle;
• and
• wherein the EDM is selectively switchable among (i) a first gear where the first torque transfer device is disengaged and the second torque transfer device is engaged grounding the carrier to the housing;
• (ii) a second gear where the second torque transfer device is disengaged and the first torque transfer device is engaged to couple for common rotation the carrier and the sun gear;
• and (iii) a neutral PTO mode wherein the first and second torque transfer devices are disengaged and the input shaft drives the PTO.
