Abstract
A differential gear mechanism includes a differential case, a first and second side gear, a first, second and third pinion gear and a center block. The differential case can define a first, second and third counterbore formed therearound. The differential case rotates around an axis of rotation. Each cross-pin can have a cylindrical pin body that extends between first and second ends. The first, second and third pinion gears intermesh with the first and second side gears to form a torque transfer arrangement. The center block can have a cylindrical body that defines a first, second and third locating feature thereon. The center block can be disposed between the first and second side gears. Each first end of a respective cross-pin is received by a corresponding counterbore of the differential case. Each second end is received by a corresponding locating feature of the center block.
