Viscous Limited Slip Differential - Explained

Опубликовано 16 января 2013, 20:00

How do viscous limited slip differentials work? Viscous limited slip differentials use a viscous coupling that allows for torque to transfer to the wheel with more grip. It is an alternative method to a clutch pack differential, though by design it is not as effective at locking the two driveshafts.

NOTE: Regarding the annotation at 2:30. I misspoke here. What happens is the right driveshaft and differential housing will both be rotating. Because the pinion gears are also rotating (green gears) around the left driveshaft gear, the right driveshaft gear will have to rotate faster than the differential housing. So, the right side of the diff will be attempting to decelerate the right driveshaft (or accelerate the diff housing) once it breaks free, while simultaneously the left side will try to accelerate the left driveshaft. Because of this, it is possible to just use a single viscous coupling on one of the driveshafts.
