  • Patent number: 10766362
    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.

  • Patent number: 10378642
    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.

  • Patent number: 10077811
    Abstract: A lubrication system (400) for a transfer case (200) includes a pump (228) selectively supplying a working fluid to a fluid reservoir of an actuator (226) configured to apply force to a clutch assembly (214) to cause the clutch assembly (214) to move between a disengaged position and an engaged position. The lubrication system also includes a relief valve (302) having a relief valve inlet fluidly coupled to the fluid reservoir of the actuator (226) which opens to receive the working fluid based on a threshold pressure level of the working fluid in the fluid reservoir. The lubrication system also includes a trough (306) fluidly coupled to a relief valve outlet of the relief valve (302). The trough (306) carries the working fluid from the relief valve outlet to a bearing assembly (227) associated with at least one of an input shaft (204) and a primary output shaft (206) of the transfer case (200) when the clutch assembly (214) is in the disengaged position.

  • Patent number: 10023041
    Abstract: A drive unit includes a housing, a main shaft, an output shaft, an electric motor, a first planetary gear set, and a second planetary gear set. The main shaft is rotatably disposed in the housing, and with the housing cooperatively defines an axis of rotation. The output shaft is disposed at least in part in the housing and is rotatable about the axis. The electric motor is disposed in the housing and has a rotor centered on and rotatable about the axis. The first planetary gear set is centered on the axis and provides a first speed reduction ratio between the rotor and a second planetary gear set. The second planetary gear set provides a second speed reduction ratio between the first planetary gear set and the output shaft.

  • Patent number: 9752671
    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.
