A transfer case () and a method of assembly in an all-wheel drive vehicle can include a range shifting assembly () for shifting between a low-range and high-range drive mode, a normally disengaged clutch assembly () for transferring drive torque to a first and second driveline, a clutch actuator (), and an actuating gear (). The clutch actuator () can be moveable between an expanded position and a contracted position and engageable with the clutch assembly () for engaging the clutch assembly () when in the expanded position. The actuating gear () can be reversibly rotatable through a predetermined angular arc of movement for operating the clutch actuator () between the contracted and expanded position for actuating the clutch assembly () and for shifting the range shifting assembly () between a low-range drive mode and a high-range mode when the clutch assembly () is in the disengaged position.

Motor driven transfer case with modular actuation

A transfer case () and a method of assembly can include an input shaft () and output shafts (), a mode clutch () for shifting between a two-wheel and four-wheel drive mode, a mode shift mechanism (), a planetary gear assembly () for providing a different drive ratio between the input shaft () and the output shaft (), a range shift mechanism (), and a synchronizer () for speed synchronization before shifting between a low-range drive mode and a high-range drive mode. A fixed ring gear () can be connected to the planetary gear assembly () during the high-range and low-range drive mode. The mode shift mechanism () and the range shift mechanism () can be electro-mechanically actuated by a reversible rotatable actuating gear () interposed between an expandable clutch actuator () and a rotatable barrel cam ().

Electro-mechanical transfer case with range shift on the move

A power transfer device for a motor vehicle having a modular housing assembly which supports a geartrain. A first embodiment of the modular housing assembly includes a case having unitary sidewall with terminal edges defining two opposed openings. The sidewall also defines an interior chamber and the openings are enclosed by a pair of cover plates. Pillow blocks are used to support the drive components of the geartrain within the chamber and are secured to shelves which extend from the sidewall. Loads created during operation are transmitted from the geartrain to the sidewall. The cover plates are secured to the terminal edges of the sidewall using a plurality of U-shaped spring clamps. A second embodiment of the modular housing assembly includes a box-like case having one open side. A cover plate is used to enclose the geartrain and lubrication fluid within the interior volume of the box-like case. A continuous support shelf is formed from the base of the box-like case and allows loads to be transmitted directly to the box-like case. A third embodiment of the modular housing assembly includes a box-like case having one open side, a cover plate used to enclose the geartrain and a continuous support shelf. Rotary and non-rotary components of the geartrain are entirely contained within the box-like case. Pillow blocks are used to support the drive components of the geartrain.
