On vehicles with permanent four-wheel drive new technical solutions have been adopted characterized by a series of devices able to guarantee optimal traction even under critical road holding conditions. These results have been obtained thanks to the adoption of a central “viscous coupling” able to transfer part of the deflecting torque from one drive shaft to another whenever there is wheel slip due to bad road conditions. Under good road holding conditions the vehicle behaves liked a front wheel drive vehicle but has the advantage that the rear axle permanently contributes to the thrust with a small torque (about 5%) transferred by the viscous coupling which, like a differential device, allows small differences in the speed of the front and rear wheels. Drive is transmitted to the viscous coupling (2) from the electromagnetic coupling (1) which is controlled by an electronic control unit which automatically engages/disengages it in accordance with evaluation parameters set by the control unit itself and measures by the relevant sensors and components. The rotating mass (3) located at the end of the drive shaft enables the vibrations generated by the imbalance of the system to be absorbed.
