Patent ID: 7988584

Claim:
A power transmitting device comprising: a differential case; a gearset received in the differential case, the gearset comprising a side gear that is received in the differential case and rotatable about an axis; and a locking mechanism comprising a first dog and a second dog, the first dog being coupled for rotation with the side gear and having a set of first dog teeth, the second dog being non-rotatably but axially slidably coupled to the differential case and having a set of second dog teeth; wherein one of the sets of first and second dog teeth comprises a plurality of pins, each of the pins extending parallel to the axis, each pin having a centerpoint, a first contact surface and a second contact surface, the first contact surface being defined by a first radius, the second contact surface being defined by a second radius and a width of the pin across the first and second contact surfaces being smaller in length than a sum of a magnitude of the first radius and a magnitude of the second radius; and wherein for a given one of the pins, a centerpoint of the first radius, a centerpoint of the second radius and the centerpoint of the given pin are disposed along a circle that is centered along the axis.
