Appl. No.:

10/108949

Inventors:

Dennis Cook - Royal Oak MI
George Leposky - Belleville MI

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

F16H 4804

US Classification:

475221, 475204

Abstract:

A power takeoff unit with torque bias capable center differential construction for four-wheel drive which includes a planetary center differential connectable to an input shaft from a transmission, the gear arrangement includes at least three nested gear components for interconnecting the input shaft with both a rear drive transfer mechanism and a planetary final drive for full-time drive such that input torque to the power takeoff unit is split between the rear drive transfer mechanism and the planetary final drive in a predetermined ratio. An electronically or mechanically actuatable friction clutch surrounds a front axle differential or can be placed between the rear drive transfer mechanism and the planetary final drive. The clutch has frictionally engageable members connected to at least one of the planetary gear components in a manner such that the torque bias to the front and rear wheel drive output shafts is controlled by a torque level established between the frictionally engagable members of the clutch.

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

F16H 4812

US Classification:

74650

Abstract:

An axle differential assembly for an automotive vehicle includes a differential housing and a central shaft rotatably mounted within the differential housing. The central shaft has opposing first and second ends, includes a ring gear mounted thereon, and defines a central axis of the axle differential assembly. A pair clutch packs are mounted to each end of the central shaft. Each of the clutch packs is adapted to connect to an end of an axle half shaft and is adapted to selectively transfer rotational motion from the central shaft, across the clutch packs, and to the axle half shafts. A pair of actuators are adapte to exert an axial force onto the clutch packs.

US Classification:

475149, 192 846, 192 94, 180247, 74665 GE

Abstract:

A transfer case for use in motor vehicles for transferring drive torque from a powertrain to first and second drivelines includes a first output shaft that is connected to the powertrain of the vehicle and is adapted to transmit drive torque from the powertrain to the first driveline. A second output shaft is adapted to transmit drive torque to the second driveline, and a transfer clutch is adapted to transfer drive torque from the first output shaft to the second output shaft. A ball screw assembly is adapted to actuate the transfer clutch.

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

F16H 4806

US Classification:

475233, 74650, 74 8923

Abstract:

A differential gear assembly for an automotive vehicle includes a differential housing. A first side gear and a second side gear are substantially axially aligned and spaced apart from one other, each of the side gears being supported by the differential housing for relative rotation therebetween and being adapted to engage an axle half-shaft. A clutch pack is mounted between and interconnects the differential housing and the first side gear. A ball screw assembly is adapted to selectively apply axial force to the clutch pack, thereby locking the first side gear to the differential housing and preventing relative rotational movement of the first side gear and the differential housing.

Assignee:

Visteon Global Technologies, Inc. - Van Buren Township MI

International Classification:

F01M001/00

US Classification:

74606R, 184 625

Abstract:

A power transfer unit includes a non-parallel gear set and a parallel gear set integrally packaged within a housing. The housing includes an extension portion that connects the power transfer unit to a transmission assembly. The extension portion is formed having a structural web with one or more cavities. These cavities include inner cavities that define a portion of the interior volume of the housing and may also include outer cavities that open to the outer side of the housing. The web between cavities provides structural rigidity for the power transfer unit, while the cavities minimize the weight of the power transfer unit.

International Classification:

F16H 37/06

US Classification:

74665GC, 74413, 74420, 74665 H

Abstract:

A motor vehicle power transfer unit for distributing torque from a transmission assembly between a front wheel drive line and rear wheel drive line. The power transfer unit includes a housing that encloses a parallel gear set and a non-parallel gear set, which are coupled between an input portion and an output portion of the power transfer unit. The parallel gear set includes a driving gear, and idler gear and a driven gear and the idler gear is rotatably supported on a non-rotating support member that extends through the idler gear. Constructed in this manner, reduced lateral compactness of the power transfer unit is achieved.

US Classification:

74424, 74606 R, 74420

Abstract:

A motor vehicle power transfer unit includes an input portion, an output portion, a non-parallel gear set and a parallel gear set. The input portion is adapted to connect to an output portion of a transmission assembly and the output portion is adapted to connect to an input portion of a rear wheel drive line. The parallel gear set is coupled to the input portion and transfers power to the non-parallel gear set, which is coupled to the output portion. The non-parallel gear set includes a ring gear having a front face with gear teeth formed therein and a rear face having a cavity formed therein. The ring gear is supported within the power transfer unit by a bearing mounted within the cavity.

US Classification:

74665GC, 74413, 74420, 74665 H

Abstract:

A motor vehicle power transfer unit for distributing torque from a transmission assembly between a front wheel drive line and a rear wheel drive line, the power transfer unit includes a housing, non-parallel gear set located in the housing and including a ring gear, and a parallel gear set including an idler, and an idler shaft secured to and supported on the housing. The idler shaft, which extends through the idler gear and supports the idler gear for rotation, includes an interior chamber, an outer surface, and a wall. A portion of the outer surface is formed with a clearance space, into which space a portion of the ring gear extends and rotates. The clearance space communicates through the wall to the chamber, the wall being formed with a hydraulic passage, which carries lubricant from the chamber to the outer surface.
