A Torsen differential, which stands for Torque-Sensing differential, is a type of limited-slip differential found in vehicles. It uses a worm gear mechanism to sense and respond to differences in torque between the wheels. When one wheel starts to slip, the Torsen differential transfers more torque to the wheel with better traction. This helps improve stability and handling, especially on slippery surfaces. Unlike standard open differentials, which can allow one wheel to spin freely when it loses traction, a Torsen differential continuously provides torque to both wheels. This ensures better grip and control. The torque transfer is smooth and immediate, without relying on electronic sensors or clutches, making the system both reliable and efficient. Additionally, its mechanical design enhances durability and longevity, making it a valuable component for improving vehicle performance and safety.
