Construction - In this type of axle the drive speed is reduced in two separate steps. The bevel pinion is driven by the propeller shaft and then d rive passed to the small crown wheel which is fixed to a lay shaft, on which is also fixed a spur pinion.

Working - The spur pinion meshes with a large spur wheel which is attached to the differential cashing just at the crown wheel of a single reduction axle.Thus the final drive is transmitted to the axle shaft.
