Four Wheel Drive
The viscous coupling does not help if both
a front and a rear wheel loose
traction as the Range Rover does not have
axle diff' locks (as standard). URL:/4WD.html Go to the Land Rover page

This is a viscous coupling as found
attached to the centre diff' in the transfer case of a Range Rover.
It has been cut away to reveal the internal plates.
These are alternately keyed to the casing or the centre shaft.
Normally a viscous fluid fills the casing and this resists strongly
large differences in rotational speed between the plates,
ie. it resists the front and rear transfer-case output shafts
rotating at very different rates.
In this role it limits wheel spin if a front (or a rear)
wheel suddenly looses traction.
The action is smooth and permits normal differential action
when cornering.
