Abstract: An axle assembly with a housing, a shaft received in the housing, a shaft bearing supporting the shaft for rotation relative to the housing about a shaft axis, a differential assembly, an annular band and a secondary retainer. The shaft bearing has an inner race, which is received on and directly engaged to the shaft, and an outer race that is received on and directly engaged to the axle housing. The differential assembly has an output member that is non-rotatably coupled to the shaft. The annular band is fixedly coupled to the shaft at a location along the axle shaft axis between the inner race and the output member. The secondary retainer is disposed along the axle shaft axis between the annular band and the output member and is configured to limit movement of the annular band along the axle shaft axis in a direction toward the output member.

The pinion gear is meshed with a ring gear that is coupled to a differential assembly. A head bearing, which is disposed on a first axial end of the input pinion, supports the input pinion for rotation relative to the housing about the first axis. A tail bearing supports the input pinion for rotation relative to the housing about the first axis. The pinion gear is disposed axially between the tail bearing and the head bearing. A bearing groove is formed into the pinion shaft and the bearing elements are received into the bearing groove such that an inner bearing race of the tail bearing is unitarily and integrally formed with the pinion shaft.

The ring gear is received in the housing and meshingly engaged with the pinion. The bearing supports the ring gear for rotation relative to the housing about a second axis and also handles thrust loads between the housing and the ring gear that are directed (in both directions) along the second axis. The bearing has a plurality of bearing elements and is abutted against a shoulder formed on the housing that is positioned along the second axis between the first axis and the bearing elements. The differential assembly has a differential case, which is coupled to the ring gear for rotation therewith, and a pair of output members that are coupled to the shafts for common rotation.

Abstract: A powertrain with a disconnecting rear drive axle generally includes a prime mover including an output that rotates about a rotational axis. A transmission includes an output that rotates about a rotational axis. The rotational axes of the outputs are substantially parallel to a longitudinal axis of the powertrain. A front driveline is operable to direct rotary power from the prime mover to front vehicle wheels. A rear driveline includes a propeller shaft that provides rotary power to a first shaft member and a second shaft member through a pinion and a ring gear. The first shaft member and the second shaft are operable to connect to rear vehicle wheels. A power switching mechanism has an engaged condition and a disengaged condition. The power switching mechanism is operable to direct the rotary power from the transmission to the rear driveline in the engaged condition. A torque transfer device has an engaged condition and a disengaged condition. The power switching mechanism and the torque transfer device in the disengaged condition are operable to only transmit rotary power to the first vehicle wheels. The torque transfer device in the disengaged condition prevents the first shaft member and the second shaft member from back-driving the ring gear and the pinion of the rear driveline. The power switching mechanism in the disengaged condition prevents the transmission from driving the propeller shaft.

Abstract: Two pairs of ribs define three intermediate cooling chambers. Each rib in each pair extends parallel to the other rib in the pair. The ribs in a first pair are non-parallel to the ribs in a second pair. A first rib from the first pair is positioned spaced toward the leading edge. A first rib of the second pair is then serially positioned spaced toward the trailing edge. A second rib of the first pair is then positioned toward the trailing edge relative to the first rib in the second pair. A second rib in the second pair is then positioned toward the trailing edge relative to the second rib in the first pair.

Abstract: A gas turbine engine is provided with a turbine rotor disk having a plurality of disk slots which each receive a turbine blade. Cooling air is delivered into the disk slots, and flows into cooling air passages at a radially inner surface of the turbine blades. As known, the cooling air flows through the turbine blades to cool internal and external surfaces of the turbine blade. The disk slots are formed to have a greater cross-sectional area adjacent at the inlet end than at downstream locations. In this manner, the velocity of the air at the inlet end is reduced compared to the prior art, and pressure losses are minimized compared to the prior art.

Abstract: An axle assembly for a vehicle. The axle assembly includes an input shaft, a first and second output shaft, and a differential assembly. The axle assembly also includes a clutch assembly with an input member coupled to the differential assembly, an output member coupled to one of the first output shaft and the second output shaft, and a clutch member that selectively couples the input and output members. The axle assembly also includes a pump that supplies pressurized fluid to the clutch to control coupling of the input and output members. The axle assembly further includes a motor that drives the pump. The speed of the motor is controllable in order to change a fluid pressure supplied by the pump. The change in fluid pressure from the pump actuates the clutch member to thereby vary the torque between the first output shaft and the second output shaft.
