Abstract
A power transmission gearbox assembly includes a motor with a rotor shaft and an input gear fixed to the rotor shaft. The input gear is part of a first gearset including a first gear disposed on a first axial side of a differential assembly having two output shafts. A second gear set having a second gear and third gear is disposed on the opposite axial side of the differential assembly. A first layshaft, radially offset from the output shafts, includes the first and second gears. A second layshaft offset from the first layshaft, includes the third gear and a fourth gear that is in meshed engagement with a differential gear. The first layshaft spans across the width of the differential gear, and does not contact the differential gear. The first and second gearsets being on opposite sides of the differential assembly reduces the axial extend of the gearbox.
