LIMITED-SLIP DIFFERENTIAL

The concept of providing traction to the nonsllpping drivewheel with a limited-slip differentlal dates back at least to the late 1950s. Though there are now many wrinkles to the old theme, the essentials are the same. The spider gears are mechanically linked to share torpue regardless of conditions. This can de done simply by adding spring-loaded clutch packs that keep the spider gears from spinning. Power the flows to both whels to the limit of the clutch packs’ capacity. The spiders can also be pneumatically or electrically locked together-but this defeats the differential function.
