Abstract: A rotor assembly includes a rotor plate, a friction shoe slidably coupled to the rotor plate and configured to move in a radial direction, and a biasing mechanism operably coupled to the friction shoe and configured to force the friction shoe in a radially inward direction. A predetermined rotation of the rotor plate imparts a centrifugal force on the friction shoe sufficient to overcome the biasing force of the biasing mechanism such that the friction shoe moves in a radially outward direction.

Abstract: A selectively lockable differential, comprising a plurality of torque sensitive pins, an outer housing, a first side gear comprising first gear teeth, a second side gear comprising second gear teeth, a pinion shaft, two pinion gears rotationally coupled to the pinion shaft, each pinion gear comprising pinion gear teeth coupled to the first gear teeth and the second gear teeth, and a collar comprising collar teeth for selectively engaging the gear lugs of the first side gear, the torque sensitive pins operatively coupling the collar to the outer housing.
