Abstract:
A family of axle assemblies that employ a modular concept to maximize part commonality amongst the several axle assemblies. The axle assemblies have a housing assembly that employs a main housing that is formed from a casting that is common to all of the axle assemblies.
Abstract:
A hydraulic system for a vehicle drivetrain includes a torque transfer device having a first actuator that actuates to selectively communicate rotatable motion from an input member to an output member. A limited slip differential selectively transfers drive torque from the output member to at least one of the first and second axle shafts. A motor drives a first and a second output shaft. A first pump is rotatably driven by the first output shaft. The first pump selectively supplies the hydraulic fluid to the first actuator. A second pump is rotatably driven by the second output shaft. The second pump selectively supplies the hydraulic fluid to the second actuator.
Abstract:
A motor drive system with a rotor assembly having an insert, which is received into a blind hollow rotor space in a shaft, a coolant inlet and a coolant outlet. The insert has an insert body, a first flow passage and a plurality of second flow passages. The insert body has an outer insert surface that is engaged to an inside surface of a shaft wall of the shaft. The first flow passage extends longitudinally through the insert body. The second flow passages extend longitudinally through the insert body radially between the outer insert surface and the first flow passage. The coolant inlet is fluidly coupled to one of the first and second flow passages, while the coolant outlet is fluidly coupled to the other one of the first and second flow passages.
Abstract:
The present teachings provide for a power transmitting component including a housing, a clutch, a vent, and a dam. The vent can fluidly couple a first and second cavity. The dam can include a door member. Rotation of the outer carrier through a fluid in the second cavity can sling a portion of the fluid toward the vent to cause the portion of the fluid to be transferred from the second cavity, through the vent, and to the first cavity. When the piston is in a first position, the door member can be in a closed position to limit fluid flow from the first cavity to the second cavity. When the piston is in a second position, the door member can be in an open position to allow fluid to flow from the first cavity to the second cavity.
Abstract:
An axle assembly that includes a housing assembly, an input pinion, a ring gear, a ring gear bearing, and a differential assembly having a differential case. The ring gear bearing supports the ring gear for rotation on the housing assembly as well as handles thrust loads between the ring gear and the housing assembly in opposite axial directions. The ring gear bearing includes an outer bearing race having a first race member, which may be unitarily and integrally formed with the ring gear, and a second race member that is received in a groove formed on the ring gear. The differential case is coupled to the ring gear and secures the second race member to the ring gear.
Abstract:
A disconnecting axle includes a housing assembly including a first end cap coupled to a first side of a housing member to define a clutch cavity, and a second end cap coupled to a second side of the housing member to define a differential cavity. The housing member can define a central bore, a sump, and a plurality of passages. The central bore extends axially between the clutch and differential cavities. The sump can be spaced apart from the clutch and differential cavities, and the central bore. A clutch passage couples the clutch cavity to the sump. A differential passage couples the differential cavity to the sump. A first output member of the differential extends axially within the central bore. A piston is configured to compress friction plates to selectively transmit torque. A pump can pump fluid from the sump to the cylinder to move the piston.
Abstract:
An axle assembly that includes a differential case which is rotatable about an axis, a pair of side gears that are disposed within the differential case, a spacer ring and a cross pin. The spacer ring is disposed between the side gears. The cross pin is fixed to one of the differential case and the spacer ring and extends through the spacer ring. The aperture in the spacer that receives the cross pin may be larger than the cross pin so that the spacer ring can control end play of the side gears independently of the cross pin.
Abstract:
A planetary transmission having a planet carrier with a carrier body and a plurality of carrier pins. The carrier body includes a pair of carrier plates, each of which having pin bosses that extend outwardly from a remaining portion of the carrier plate. The pin bosses on at least one of the carrier plates define an exterior surface with at least one step so that portions of the exterior surface of the pin bosses are spaced apart in an axial direction. The carrier pins have an axial ends with recesses formed therein such that each axial end of each carrier pin terminates in a thin wall section. The carrier pins are received through the carrier plates and the thin wall sections are deformed against the exterior surfaces of the pin bosses to retain the carrier pins to the carrier body.
Abstract:
An electrically-operated electric drive module for use in a vehicle framework that is configured for a powertrain that includes an internal combustion engine. The electrically-operated electric drive module permits the vehicle to be converted to an electrically propelled vehicle in a manner that is cost-effective and which is relatively low in weight.
