Patent ID: 7722495

Claim:
A differential carrier for a vehicle, said differential carrier causing oppositely disposed wheels mounted on first and second axle shafts to simultaneously and continuously rotate in response to rotation of said differential carrier, said differential carrier comprising: a rotatable differential carrier housing, said housing having first and second shaft openings, said first shaft opening adapted to receive the first axle shaft and said second shaft opening adapted to receive the second axle shaft; said housing further including a first housing cavity and a second housing cavity, said first housing cavity being disposed internally of said housing adjacent said first shaft opening and said second housing cavity being disposed internally of said housing adjacent said second shaft opening; and a first permanent differential locking member and a second permanent differential locking member; said first locking member having a first locking hole with said first locking hole having first hole teeth immovably linking said first locking member with the first axle shaft, said first locking member including a first locking protrusion projecting from said first locking member, said first locking member being installed in said first housing cavity with said first locking protrusion mechanically engaging said housing such that said first locking member rotates simultaneously with rotation of said housing, whereby said first locking member causes the first axle shaft to rotate; said second locking member having a second locking hole with said second locking hole having second hole teeth immovably linking said second locking member with the second axle shaft, said second locking member including a second locking protrusion projecting from said second locking member, said second locking member being installed in said second housing cavity with said second locking protrusion mechanically engaging said housing such that said second locking member rotates simultaneously with rotation of said housing, whereby said second locking member causes the second axle shaft to rotate.
