How does a Torsen differential limit slip between the wheels?

A Torsen differential limits slip between the wheels through a torque-sensing mechanism that relies on worm gears and spur gears. Unlike an open differential, which transmits equal torque to both wheels regardless of traction, a Torsen differential biases torque towards the wheel with more traction. A Torsen differential uses sets of worm gears and spur gears to connect the two axles. The worm gears can only transmit torque from the carrier to the side gears (axles), not from the side gears back to the carrier. This creates a "torque bias r....
