Limited Slip Differentials Greg Reale
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 • TorsenTM • Senses difference in torque • Uses gears that bind together
