Abstract
A number of variations may include a transfer case comprising: a clutch pack, wherein the clutch pack includes a first plurality of clutch plates rotatably coupled with an output member, a second plurality of clutch plates interleaved with the first plurality of clutch plates and rotatably coupled with an input member, and an apply plate; a solenoid operably associated with the friction clutch pack, wherein the solenoid includes a coil and an armature; at least one lever mechanism, wherein a first end of the at least one lever mechanism is stationary and a second end is attached to and moves with the armature; and wherein when the solenoid is deenergized there is an air gap between the armature and the coil and when the solenoid is energized the armature moves toward the coil causing the first end of the lever component to engage the clutch pack.
