The Torsen-differential (torque-sensitive) should compensate for any small RPM differences, e.g., between the front- and rear axle and lock this offset for a short time when greater RPM differences occur, without notable wear and tear. In the case of locking wheels, it should influence, without electronics, the ABS function as little as possible.

Please switch over to figure 2. Here it goes left to the rear- and right to the front axle. The rear-axle worm-gear on the right is (red) linked with the three left worm-gears, in the casing. The same is found (in pink) on the front-axle-side . The straight-cut gears (yellow, blue and green) in the three worm-gears on the left in the casing, are linked with the straight-cut gears on the right in the casing.

When driving in a straight line the casing and both worm-gears, for front-and rear axle, turn identically. The six worm-gears in the casing transfer the torque steadily, and do not turn. Should the rear axle stand, e.g., on black ice, the worm-gear would not rotate, thus, without any locking effect on the front axle. The straight-cut gears of the three worm-gears on the right in the casing, would mesh with those on the left to drive the three worm-gears.

Thus the worm-gear to the rear axle would have double the RPMs. However, the diagonal gearing of the respective worm-gears, (red and pink) prevents smooth rolling. Depending on the angle of the diagonal gearing, some torque will also always be transferred to the front axle. The locking effect develops from the auto-inhibition of the two diagonal gearings, as is typical for worm-gears. The exact percentage of this locking effect is determined by the degree of the diagonal gearing. 11/08.
