  1. Limited Slip Differential By: Khashayar Toutounchian Instructor: Kevin Cedrone

  2. Why you need a differential • Car wheels spin at different speeds, especially when turning. • Wheels would have to be locked together, making turns difficult on the car. • Differential transmits the force through the axle from one wheel to another to prevent slippage of a tire

  3. Limited Slip Differential (LSD)or Positraction • Uses various mechanisms to allow more torque to be transferred from a slipping wheel to the non-slipping wheel. • Clutch-type LSD has the same components as an open differential, plus a spring pack and a set of clutches.

  4. How LSD works? • Clutch packs inside the differential create additional resistance. The resistance is always present. • The tire has to overcome the traction present plus the preload resistance to spin faster. • Traction and preload have to be high enough to keep tires from spinning but low enough to still allow tires to rotate at different speeds in a turn.

  5. How useful is LSD? • LSD limits the slippage but doesn't prevent it. • It works in easy off-road conditions or on mildly slippery roads, but for serious slippery or off-road use its not powerful enough.
