Abstract: A transfer case comprises a primary output shaft, and a secondary output shaft selectively coupleable to the primary output shaft with a plate clutch to transfer torque therebetween. The plate clutch includes a housing, a plurality of interleaved plates that are engaged alternatingly with the primary output shaft and the housing to rotate therewith, and an apply plate non-selectively coupled to the primary output shaft to rotate therewith. The apply plate is moveable axially along the primary output shaft into a first configuration in which the apply plate is positively coupled to the housing to rotate therewith, a second configuration in which the apply plate rotates independent of the housing, and a third configuration in which the apply plate compresses the interleaved plates to form a friction coupling between the primary output shaft and the housing.

Abstract: A drive module with a housing, an electric motor coupled to the housing, a differential assembly, a transmission, and a filter-strainer assembly. The housing has an exterior wall member that defines an internal cavity and a suction tube. The internal cavity at least partly forms a lubricant sump with a sump outlet. The suction tube is spaced apart from and does not intersect the internal cavity such that the suction tube is not in direct fluid communication with the internal cavity. The differential assembly and transmission are received in the internal cavity and the transmission transmits rotary power between the electric motor and the differential assembly. The filter-strainer assembly is coupled to the housing and has a filter-strainer inlet, which is coupled in fluid communication to the sump outlet, and a filter-strainer outlet, which is directly coupled in fluid communication to a suction tube inlet of the suction tube.

Abstract: A power transmitting component with a differential assembly and a planetary reduction that has a plurality of compound planet gears. Each of the compound planet gears is rotatable about a rotary planet axis and has first and second planet gears that are nonrotatably coupled to one another and spaced axially apart from one another along an associated one of the rotary planet axes. The rotary planet axes are disposed concentrically about a rotational axis of the input to the planetary reduction. Each of the first planet gears is meshingly engaged to the input of the planetary reduction, while each of second planet gears is meshingly engaged with a stationary ring gear. The differential assembly receives rotary power from the planetary reduction and has first and second differential outputs that are disposed along the rotational axis between the first and second planet gears.

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 transfer case is provided with a primary shaft which is selectively engagable with a secondary shaft via a clutch mechanism. The clutch mechanism is inclusive of a friction pack. A hub of the clutch mechanism is connected on the primary shaft and the clutch housing is torsionally fixed with a primary sprocket rotatively mounted on the primary shaft. A passive or active controlled lubricant collection receptacle is provided which maximize fluid retention in conditions wherein there is not a high demand of torque for the clutch system of the transfer case thereby minimizing fluid that is unnecessarily churned by engagement with the hub connected with the secondary shaft.
