HYDRAULICALLY ACTUATED TRANSFER CASE

A drive torque transfer case is provided. The transfer case includes an input shaft, an output shaft, a gear assembly coupled to the input shaft, and a range clutch assembly coupled to the output shaft. The range clutch assembly includes a clutch member and a multi-piston actuator configured to receive a pressurized transmission fluid for selectively axially translating the clutch member to engage a component of the gear assembly for transmitting a drive torque from the input shaft to the output shaft. The multi-piston actuator includes an internal piston having a first annular surface area A and a third annular surface area A and an external piston having a second annular surface area A and a fourth annular surface area A The A and A are in hydraulic communication with a first hydraulic chamber, and A and A are in hydraulic communication with a second hydraulic chamber.
