Abstract
A differential assembly includes an axle, a differential, a differential lock, a blocking member, and a pump. The differential is coupled with the axle and configured to facilitate operation of the axle at an axle speed. The differential lock is associated with the differential and movable between a locked position and an unlocked position. The blocking member is associated with the differential lock and is movable between a blocking position and a non-blocking position. When the blocking member is in the blocking position, the differential lock is inhibited from moving to the locked position. The pump includes an outlet in fluid communication with the blocking member. The pump is operably coupled with the axle and is configured to facilitate movement of the blocking member into the blocking position when the axle speed is above a threshold speed. Vehicles including a differential assembly are also provided.
