The Torsen dates back to 1983. Since then it has been used by various carmakers, including Audi and Hummer. The Torsen multiplies what torque is available from the axle that is starting to spin or lose traction, and sends it to the slower-turning axle with better traction. The gears allow a torque-bias ratio of 4:1, which means they can deliver four times as much power to the non slipping axle than can be supported by the slipping axle. One big advantage of Torsen systems is that because they are purely mechanical, they react very quickly to slip.
Most often, loss of control is compounded by vehicle’s inability to recover or to cope with hazardous road surface. The TORSEN Traction differential increases the margin of safety by improving a vehicles’s capability to manage unexpected road conditions. TORSEN works continuously, providing a more stable and controllable driving platform, which could help to reduce the chance of a potential accident before it can occur.
In normal driving conditions, power from the engine is equally distributed to both the axles resulting in equal traction between both the wheels. while this configuration is ideal for normal straight line driving,its unsuitable for variable road surfaces like ice, snow, mud etc..
Loss of traction causes wheel spin, a potentially dangerous condition on slippery roads. unlike conventional speed sensing LSD’s(Limited Slip Differential),TORSEN Traction Differentials respond instantly, shifting power to the wheel with the most traction.There is no wheel spin, lag time or momentary loss of traction.
How TORSEN Traction Differential works
The TORSEN Traction differential is designed to outperform conventional differentials. It is an advanced and highly efficient traction control system engineered to effectively manage power (torque) distribution and traction management. Unlike limited-slip differentials, the TORSEN Traction Differentials has no clutches to slip or wear out. Instead. it is an on-demand, torque sensing, torque biasing system.The driven axles are directly coupled through patented INVEX,EQUIVEX

PLANETARY GEARS
, or planetary Helical gears allowing multifunction capabilities in one integral unit. Torque transmission,torque biasing and differentiation, essential functions for effective traction control, are performed simultaneously,all in one compact unit. For center applications, front or rear biased torque splits are also possible. Because it is a solid, no-slip geared system, the TORSEN differential will perform for the life of the vehicle.
