ABSTRACT:
Differential comprising disks (1, 2) and rings (3, 4) inside a casing (15) being in full and continuous sliding state of contact with the outer pair of disks (6, 7) coupled to the output shafts. The inner sides of disks (1, 2) and rings (3, 4) are machined so that the plane surfaces on both sides of configurations (8, 10) and (9, 11) are inclined towards the perimeter under a certain inclination angle, allowing the convergence and divergence of the disks around configurations (8, 10). The outer plane surfaces of disks and rings of the inner pair (1, 2, 3, 4) are in full and continuous contact with the inclined circular planes (12, 13, 14) of the outer pair of disks (6, 7). On the periphery of the ring (3) are fitted plates (5) which can slide in a recess (16) of the inner surface of the casing (15). The configuration and arrangement of axles, disks, and rings allow the mechanism to move in a peculiar way, with harmonious rotation oscillations and achieving blocking in the case of partial or total adhesion loss of one driving wheel and the delivery of the remaining or even the whole torque to the wheel with greater adhesion and traction.
