Abstract:
A power transfer assembly for a vehicle including an input shaft, at least one output shaft, and at least one clutch configured to perform at least one of changing a gear ratio between the input shaft and the output shaft, and coupling the input shaft with a second output shaft of the at least one output shaft. An actuator assembly is configured to activate the at least one clutch. The actuator assembly has a motor with an output drive, a worm gear coupled with the output shaft, and a spur gear meshed with the worm gear and coupled with the at least one clutch for activating the at least one clutch. The worm gear and the spur gear have opposite gear hands.
Abstract:
An integrated pinion/bearing/coupling (PBC) assembly for use with a hypoid gearset in power transfer assemblies of motor vehicles having mounting features and venting features, The integrated PBC assembly includes a hollow pinion unit made of steel and including a pinion shaft segment and a pinion gear segment, and a coupling unit having a hub segment made of aluminum. A brazing sleeve is used to braze the aluminum hub segment of the coupling unit to the steel pinion shaft segment of the pinion unit.
Abstract:
A transfer case for use in a four-wheel drive vehicle and having a clutch assembly disposed on a front output and a pass-through rear output arrangement. The front output is a front output shall. The rear output is established by directly interconnecting a transmission output shaft to an end segment of a rear propshaft. A transfer assembly is driven by the transmission output shaft and can be selectively coupled to the front output shaft via the clutch assembly.
Abstract:
One implementation of a vehicle power transfer unit (PTU) housing, suchas that for an automobile, has an oil feed passage extending through one of its walls and at its interior. The oil feed passage delivers oil to gears, bearings, and/or other components equipped inside of the PTU housing and suspended above an oil bath in the PTU housing. Oil of the oil bath is thrown about by rotating gears and makes its way through the oil feed passage and to the gears, bearings, and/or other components. With the oil feed passage, the PTU housing does not rely solely on oil sloshing and splashing and being slung around inside of the PTU housing as the technique for getting oil to the gears, bearings, and/or other components.
Abstract:
An ADD mechanism (7) and a motor generator (8) are provided between a front differential device (41) and a right front wheel (4R) in a rear wheel drive-based four-wheel-drive vehicle. In a two- wheel drive mode, the ADD mechanism (7) is released to stop rotation of a ring gear (43) fixed to the front differential device (41) in order to avoid co-rotation. In a four-wheel drive mode, the ADD mechanism (7) is engaged such that a drive force of the right front wheel (4R) is increased during a left turn by causing the motor generator (8) to output a torque in a normal rotation direction, and a drive force of a left front wheel (4L) is increased during a right turn by causing the motor generator (8) to output a torque in a reverse rotation direction.
Abstract:
A transmission system, comprising first and second variators (101, 107); first, second and third source/sink (100, 111, 122) couplings; and reconfigurable mechanical linkage coupling the first and second variators (101, 107) to the first, second and third source/sink (100, 111, 122) couplings; wherein the mechanical linkage is configurable for power transfer between at least two of said source/sink couplings via one of said first and second variators or via both of said first and second variators (101, 107).
