Limited Slip Differentials Presented by Jacky Lau Block
Limited Slip Differentials Presented by: Jacky Lau Block: 8 M-I
Objective: investigate the use, way of function, and design of LSDs l understand LSDs’ role in the performance of modern cars l Limited Slip Differentials (LSD), presented by Jacky Lau
Wheel speeds in a car wheels spin at different speeds l especially in turns l speed = distance / time l http: //isobe. typepad. com/photos/uncategorized/041213_wheel_tracking. jpg Limited Slip Differentials (LSD), presented by Jacky Lau
What does a differential do? to aim the engine power at the wheels l to act as the final gear reduction in the vehicle, slowing the rotational speed l to transmit the power to the wheels while allowing them to rotate at different speeds l Limited Slip Differentials (LSD), presented by Jacky Lau
Without differentials, what will happen? wheels would be locked together, forced to spin at the same speed l difficult to turn l tires and axle components will experience heavy stress l Limited Slip Differentials (LSD), presented by Jacky Lau
Differentials- definition and location l Definition: a device that splits the engine torque two ways, allowing each output to spin at a different speed. http: //auto. howstuffworks. com/differential 2. htm Limited Slip Differentials (LSD), presented by Jacky Lau
The LSDs (positraction) clutch-type LSD, the viscous coupling, locking differential and Torsen differential l most common type : clutch l http: //auto. howstuffworks. com/differential 8. htm http: //www. club 4 ag. com/faq%20 and%20 tech_pages/limited_slips_diff erential_101. htm Limited Slip Differentials (LSD), presented by Jacky Lau
LSDs (continued) viscous coupling – often used in AWD cars, linking the rear and front wheels l locking – serious off-road vehicles l http: //auto. howstuffworks. com/differential 10. htm Limited Slip Differentials (LSD), presented by Jacky Lau
