Abstract
A transfer case is disclosed that includes an input shaft, a primary output shaft, a secondary output shaft, a gear reduction mechanism that selectively couples the input shaft to the primary output shaft in a high range and a low range, a secondary torque transfer mechanism that operates to selectively couple the primary output shaft to the secondary output shaft to engage a four-wheel drive mode, and an actuation mechanism that operates the gear reduction mechanism and the secondary torque transfer mechanism. The actuation mechanism includes a gear plate with an integral target pattern that is rotatable through a plurality of positions corresponding to states of the gear reduction mechanism and the secondary torque transfer, as well as a sensor that is adapted and positioned to read the target pattern to in each of the positions of the gear plate.
