ABSTRACT:
A differential device has a drive shaft, a pair of cones connected to it so as to rotate at the same speed, a pair of wheel shafts with a pair of ring wheels fitted on them such that the ring wheels are engaged in a rotational direction with conical surfaces of the cones. The ring wheels are slidable in an axial direction and are positioned parallel to the axis of the corresponding wheel shafts. The ring wheels are transmissively in contact with the outer conical surfaces of the pair of cones. A steering mechanism is included for moving these ring wheels axially on the wheel shafts proportional to the amount of steering. A pair of brake teeth are on the ring wheels and a corresponding pair of brake teeth are attached to a fixed casing. When one of the ring wheels moves toward a smaller-diameter side of the corresponding cone, and gets off of the corresponding conical surface, the other ring wheel keeps making transmissive contact with a larger diameter of the other cone corresponding to the other ring wheel. Also when one of the ring wheels gets off the conical surface, the brake teeth of that ring wheel can mesh with the corresponding fixed brake teeth while the other ring wheel keeps making transmissive contact with a larger-diameter of the other cone corresponding to the other ring wheel.
