Discovered this at a Russian website - which seem to be some sort of a Torsen ?:



DAK "Niva" Front Axle

"Field" (WHA 2121) and modifications. Date of issue until April 2004.

Bearing 33h62h16 mm - 707 Semiaxis 22 slot.

Automatic Differential Krasikova designed to work in any transmissions wheel vehicles on various roads and off-road, in vsёh range of speeds and loads.

Kinematic scheme Duck scheme is similar to the classical differential. AIBN planetary gear in which the role played by the satellite ball chain.

For uniform motion, when present in Dhaka relative balance of power, ball chain moves freely along the channels and how to redistribute power satellite (N = M * w) equally between the wheels. Car maneuvers as a free differential. In contrast to the limited slip differential in this mode of AKD creates resistance to rotation.

In case of violation of equality of forces (different coefficients of resistance on wheels, a sharp acceleration or engine braking), ball chain is loaded, the ratio of reaction forces in turning the channel is such that the chain is locked. Differential lock. The principle is similar to the principle of self-locking locking worm gear. The more is loaded, the more locked DAK.

DAK does not respond to the speed difference of the wheels, and the difference of loads on the drive wheels and engine thrust.

Why AIBN locked in one direction by 100%, and in the opposite direction by 90%?

When the slope of the helical grooves of the screws pointing in different directions ahead of the vehicle (Fig. - Rotation of the body from top to bottom), is loaded with ALL ball chain that is locked in the rotary channel.

When the slope of helical grooves directed towards the screw (Fig. - The rotation of the housing bottom to top), loaded to a greater extent of the chain in direct contact with the screws. Another part of the chain in contact with the rotary channel remains underused. Component force that locks the chain in a rotary ball channel is insufficient to lock the differential. You must reload "weak" wheel external influence. Weak wheel is called a wheel that has a lower coefficient of drag. Strong wheel is called the wheel which has a larger coefficient of resistance.

90% -tsifra conditional, it just means that to create the conditions necessary to block the external load on a weak wheel. But while in the locked state DAK transmits 100% of the load on the wheel strong. This is the main difference from Dhaka slip differential, where the time for a strong wheel is transmitted to the extent that it can keep the friction pair.

DAK - automatic feedback system, its response to changing road conditions instantaneously (torque response on the wheel, not the speed of rotation). The car, equipped with a differential DAC acquires driving stability on slippery surfaces.

Continuity, stability and all-terrain vehicle is substantially increased.

The slots at the diff Housing makes me think that this might NOT be a Torsen:





Does anyone have any experience with those diffs ?
Maybe it is NOT a Torsen ?
My Wringlish is not too good, and unfortunately I do not fully understand the details above Embarassed

Oops......since my previous post I did a Google search about these diffs, and I discovered this :

http://forum.difflock.com/viewtopic.php?t=56644

The photos and product at my initial post have been listed only four days ago as "new" product - at the website where I found the product.........maybe it is just the very (uninproved ?) product which has been discussed a couple of years ago at the link above..
