  • Patent number: 8998764
    Abstract: A drive module with a planetary transmission that includes a transmission housing, a first ring gear and a second ring gear. The first ring gear is rotatably mounted in the transmission housing, the second ring gear is non-rotatably mounted in the transmission housing, and the first ring gear is supported on the second ring gear to thereby align a central axis of the first ring gear to a central axis of the second ring gear.

  • Publication number: 20140364264
    Abstract: An axle assembly with a differential assembly, a housing and a transmission. The transmission has a first and second planetary gearsets that have associated (i.e., first and second) ring gears, planet carriers and sun gears. The first planet carrier is coupled to a differential carrier of the differential assembly for common rotation. The second ring gear is non-rotatably coupled to the housing. The second planet carrier is coupled to the second differential output for common rotation. The second sun gear is coupled to the first sun gear for common rotation.

  • Publication number: 20140265658
    Abstract: A drive module with a housing, an electric motor, a coolant sump, an inlet pipe and a transmission and differential assembly that is driven by the electric motor to drive a pair of output members. The electric motor is coupled to the housing and has a stator, which is fixedly coupled to the housing, and a rotor that is rotatable within the stator. The rotor has a coolant passage, which extends parallel to a rotational axis of the rotor, and a nozzle passage that intersects the coolant passage and extends radially outwardly therefrom. The coolant sump is configured to hold a coolant fluid. The inlet pipe is in fluid communication with the coolant sump and is received into the coolant passage. The inlet pipe is configured to feed the coolant fluid from the coolant sump into the coolant passage. The coolant fluid is gravity fed into the inlet pipe.

  • Patent number: 8651991
    Abstract: A drive module that includes a housing, first and second axle shafts, a differential assembly, a propulsion motor, a brake element fixed to the housing, a torque-vectoring transmission and a mode gear. The differential assembly is mounted in the housing for rotation about a rotational axis and has a differential case and a pair of output members. A first one of the output members is coupled to the first axle shaft for common rotation. The torque-vectoring transmission cooperates with the differential assembly to transmit rotary power to the second axle shaft. The mode gear is movable between a first position and a second position. Positioning of the mode gear in the first position permits transmission of rotary power between the propulsion motor and the differential assembly. Positioning of the mode gear in the second position couples the differential assembly to the housing to inhibit rotation of the first axle shaft.
