ABSTRACT:
The device combines the functions of a self-locking differential and a torque divider and operates to a prescribed ratio between the two driven halfshafts. The adjacent ends of the two halfshafts (1, 2) carry respective worms (11, 21), dissimilar in diameter, each paired with at least one worm wheel; these two worm wheels (12, 22) are carried by the cage (3) of the differential, and interconnected in rotation by way of a mechanical train having an overall transmission ratio matched exactly to the ratio existing between the pitch diameters of the worms (11, 21).
