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.

Abstract: A transfer case of a motor vehicle drivetrain includes a planetary gear set including a ring gear to receive input torque, and a pinion assembly having pinion gears in mesh with the ring gear and a carrier to carry the pinion gears and transmit output torque. A sun gear is in mesh with the pinion gears, is selectively connectable to the carrier and rotatable therewith in a two-wheel drive mode and in a four-wheel-drive high range mode, and is selectively fixable against rotational motion in a four-wheel drive low range mode.

Abstract: A transfer case (14) of a motor vehicle drivetrain includes a planetary gear set (80) including a ring gear (82) to receive input torque, and a pinion assembly (84) having pinion gears (100) in mesh with the ring gear and a carrier (102) to carry the pinion gears and transmit output torque. A sun gear (86) is in mesh with the pinion gears, is selectively connectable to the carrier and rotatable therewith in a two-wheel drive mode and in a four-wheel-drive high range mode, and is selectively fixable against rotational motion in a four-wheel drive low range mode.
