FRICTION CLUTCH LOADING
The loading of the friction clutches is effected by three different
methods-
1. Belleville Spring. Since one of the plates in each clutch pack is
dished to form a Belleville spring, the clutches are under a certain amount
of pressure at all times and there is, therefore, effective restraint of free
differential action, even if one wheel is clear of the ground. This point is
of great importance, since the other means of loading are dependent
on
the degree of re-action at the axle shafts.

2. The Separating Forces of the Differential Gears. As described, the
differential side gear abuts against the side gear ring and the axial loading,
due to the separating forces of the differential gears, is therefore transmitted
to the clutch pack and this loading will be directly proportional to the
torque transmitted by the gears.
