This places unnecessary load
on the front axle, differential and drive shaft. AVM free
wheeling hubs disconnect the front axles from the front
hubs. Disconnected, the front wheels are 'free' to turn
while axles, differential and drive shaft remain stationary
inside the axle housing.
This reduces unnecessary
wear and tear on these components and saves fuel. How the
hub achieves this is quite simple. At the outer end of each
front axle is a splined section over which the inner hub
fits. Around the outside of this is an outer hub which is
connected to the wheel. A clutch separates the two. This
clutch can be engaged by oblique grooves cut inside the
free wheeling hub control knob that is mounted on the outside.
Turning the knob from '2' to '4WD' (or from 'free' to 'lock')
moves the clutch so that it locks the inner and outer hubs
together. Once this has been done drive from the axle will
reach the wheels. For normal 'on road' or hard surface usage,
4WD is not required and the hubs should be placed in the
'free' position. If 4WD is required or likely to be required,
the hubs should be turned to the 'lock' position. The AVM
free wheeling hub is a tough and dependable hub which is
easily fitted and features a heat treated, steel clutch
ring for faultless torque transmitting. AVM hubs are built
from corrosion resistant materials and provide positive
clutch ring positioning, with engage/disengage springs totally
independent.
