Torque limiting differential

A selectively lockable differential, which comprises a plurality of torque sensitive pins; an outer housing; a first side gear comprising first gear teeth and gear lugs; 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 collar being operatively coupled to the outer housing by the torque sensitive pins. In addition, a vehicle driveline comprises a torque transmission system operatively coupled to transmit torque from an engine to a selectively lockable differential. The selectively lockable differential may comprise a plurality of torque sensitive pins, an outer housing, a first side gear comprising first gear teeth and gear lugs, a second side gear comprising second gear teeth, and a pinion shaft. two pinion gears may be rotationally coupled to the pinion shaft. Each pinion gear may comprise pinion gear teeth coupled to the first gear teeth and the second gear teeth. A collar may comprise collar teeth for selectively engaging the gear lugs of the first side gear. The collar may be operatively coupled to the outer housing by the torque sensitive pins. A first axle may be operatively coupled to the first side gear, and a second axle may be operatively coupled to the second side gear.
