What Are They Used For? Open Slip Differentials: • Same amount of torque between each wheel • Amount of torque applied is limited • Problem Scenarios – Slipping on ice – Off roading Limited Slip Differentials: • Allow different amounts of torque to be applied to each wheel
Types of Limited Slip Differentials • Mechanical – Spring-pack and clutches – Spring forces side gears against clutches – Clutches “fight” each other – Torque applied to wheels is same as torque required to overpower clutches
Types of Limited Slip Differentials • Fluid-Based (Viscous Coupling) – Links front wheels to back wheels – Consists of plates and viscous liquid – Viscous liquid transfers torque through plates – Viscosity of liquid affects amount of torque
Types of Limited Slip Differentials • Locking – Electric, hydraulic, or pneumatic mechanism – Activated manually by switch – Wheels are forced to spin at same speed – For serious off roading • Torsen. TM – Senses difference in torque – Uses gears that bind together
