Abstract
An electric drive unit includes a housing, a motor, a sleeve, first and second seals, and a bearing. The housing defines gearbox and motor housing regions, and first and second channels extending between the gearbox and motor housing regions. The motor is disposed within the motor housing region and has a rotor and a rotor shaft that is rotationally driven about an axis. The sleeve extends circumferentially along an exterior surface of the rotor shaft and has an inner surface that interfaces with the exterior surface, and an outer surface opposite the inner surface. The first seal extends between the outer surface of the sleeve and the housing. The second seal extends between the inner surface of the sleeve and the exterior surface of the rotor shaft. The bearing is positioned radially between the rotor shaft and the housing and axially between the first seal and the gearbox region.
