Abstract
A differential device is comprised of a casing with a first end wall and a side wall forming a corner with the first end wall; a differential gear set including an input gear and first and second side gears that are so meshed with the input gear to allow differential motion between the first and second side gears; and a clutch member being housed in and axially movable in the casing from a first position where the clutch member engages with the first side gear to limit the differential motion to a second position where the clutch member rests on the first end wall and frees the first side gear, the clutch member slidably fitting on the first side gear so as to keep the clutch member concentric with the first side gear.
Claims8
A differential device having an axis, the differential device comprising:
- a casing rotatable about the axis, the casing including a first end wall rising from the axis and a side wall forming a corner with the first end wall;
- a differential gear set being housed in and drivingly coupled with the casing and including an input gear and first and second side gears rotatable about the axis, the first and second side gears being so meshed with the input gear to allow differential motion between the first and second side gears;
- and
- a clutch member being housed in and axially movable in the casing from a first position where the clutch member engages with the first side gear to limit the differential motion to a second position where the clutch member rests on the first end wall and frees the first side gear, the clutch member slidably fitting on the first side gear so as to keep the clutch member concentric with the first side gear.
