Abstract: A passive lubrication system, for a gear drive system of a drive system, for powering an electric vehicle, includes an oil network, an oil sump region, an oil paddle, and an oil diverter. The oil network is defined by and disposed within, at least, a fixed annular region of the gear drive system and a planetary gear system. The oil sump region is configured to provide oil for distribution about the oil network. The oil paddle is operatively coupled with the planetary gear system, configured to rotate with a component of the planetary gear system, and during rotation, configured to course oil, from the oil sump region. The oil diverter is positioned concentric with the oil paddle and radially outward of the oil paddle and configured to receive oil from an oil source, upon rotation of the oil paddle, and direct the received oil to the oil network.

Abstract: A product may include a pair of rotating elements. A coupling may be connected between the pair of rotating elements. An actuator may be connected to the coupling and may engage and disengage the pair of rotating elements from each other. A valve may be connected with the actuator and may effect a supply lubrication to the coupling when the pair of rotating elements are engaged through the coupling.

Abstract: A transfer case includes a primary output shaft, and a secondary output selectively coupleable to the primary output shaft with a secondary torque transfer mechanism. The secondary torque transfer mechanism comprises a plate clutch and a locking sleeve. The plate clutch includes a housing coupled to the secondary output shaft, a plurality of interleaved plates alternatingly coupled to the primary output shaft and the housing, and an apply plate coupled to the primary output shaft and being configured to compress the interleaved plates to selectively form a friction coupling between the primary output shaft and the secondary output shaft. The locking sleeve is non-selectively coupled to one of the housing or the apply plate to rotate therewith, and is selectively coupleable to the other of the housing or the apply plate to form a positive coupling between the primary output shaft and the secondary output shaft.

Abstract: A transfer case for a motor vehicle. An input is rotatable about an axis to receive torque, an output is rotatable about the axis to transmit torque, and a planetary gear set is rotatable about the axis and operatively coupled between the input and the output. A shift sleeve circumscribes and is axially slidably carried along the axis, and a shift sleeve lock is automatically engageable with the shift sleeve responsive to the transfer case exceeding a predetermined rotational speed, to prevent axial movement of the shift sleeve above that speed. A related method is also provided.

Abstract: An axle disconnect assembly for translating rotational torque between an output shaft and an axle shaft of a vehicle driveline; including: disconnect housing and a clutch supported therein. The clutch is disposed in selective torque translating relationship between the output shaft and the axle shaft, and is movable between: an engaged configuration wherein torque is translated between the output shaft and the axle shaft; and a disengaged configuration wherein torque is interrupted between the shafts. An electromagnetic actuator is provide and has a slider selectively movable between a first stable position and a second stable position. The actuator is disposed in force translating relationship with the clutch such that movement from one stable position to the other stable position causes corresponding movement of the clutch between the configurations so as to selectively translate rotational torque between the output shaft and the axle shaft.

Abstract: The present invention relates to a transfer case (16) lubrication system (42) that includes a housing (44) defining a chamber and having a lower portion (58). A partition (46) extends from the lower portion (58) and is disposed in the chamber so as to define a reservoir for oil, adjacent to the partition (46) and spaced from the chamber. First and second sprocket (50)s are supported in the chamber, with the first sprocket (48) being spaced from the reservoir. The system also includes a pump assembly (52) having an oil pump (78), a pickup (80) in fluid communication with the pump and at least partially disposed in the reservoir, and a spray bar (82) in fluid communication with the pump for directing oil from the reservoir to a predetermined location within the chamber. A chain (54) connects the sprockets and is spaced from the partition (46) so as to generate a windage force for transferring oil from the chamber to the reservoir in operation.
