Improved Differential Function for Avoiding Slippage of Motor Vehicles in a Muddy Trench 2002-01-0988
Vehicles such as trucks, buses and cars often get struck up in muddy trenches or in snow with one of wheels in the trench and the other on level ground. With an open differential, driver's effort to pull the vehicle out normally ends up with one wheel, which is rotating still going deeper into the trench. Until now Limited Slip Differentials (LSD), Locked Differentials and Viscous Coupling etc. have been used to overcome this difficulty but with limited success.
Incorporating logic devices has developed a novel solution to this problem and the traction on the required wheel is achieved automatically. The system works independently of the conventional brakes.
