Differential Assembly: Description and Operation

3908 Drive Set

The drive set is designed as a hypoid drive. This means that the center axis of the ring gear is positioned above the center axis of the drive pinion. Hypoid drives with the same ring gear size can transfer higher torques due to the sturdier construction of the teeth of the drive pinion. The changed ring gear position also allows for decreased deflection angles on the drive shafts.

The drive pinion is hollow, in order to reduce the weight and to enable lubrication. The drive pinion incorporates cross holes for the purposes of lubrication.
