On the passive limited slip differential for high performance vehicle applications

The paper is aimed at a comprehensive revision of the working principles and limitations of the mechanical limited slip differential, the traditional, passive device used to improve traction capabilities and to extend the performance envelope of high performance road cars, racing and rally cars. Its impact on vehicle handling through a yaw moment generated with passive torque distribution across the drive axle is investigated by means of vehicle dynamics simulations.
