Abstract
An auxiliary differential mechanism for a work vehicle includes a housing fixed with respect to the differential, a main shaft extending within the housing along a rotation axis and configured to couple to the differential and rotate about the rotation axis, and a wheel shaft extending along the rotation axis and configured to rotate about the rotation axis to drive the ground-engaging wheel or track. A brake is located between the main shaft and the housing, and a brake piston is configured to selectively engage the brake to ground the main shaft to the housing. A clutch is located between the main shaft and the wheel shaft, and a clutch piston is configured to selectively engage the clutch to tie the wheel shaft to the main shaft to corotate together. An intermediate piston between the brake and the clutch is selectively movable to engage the brake or the clutch.
