The Effect on the Stability of Rear Drive Vehicle with Viscous Limited Slip Differential

Abstract:

This article reflects the influence on the limited slip differential (LSD) for the rear drive vehicle handling and stability through the process of stress analysis of automotive steering movement, where the vehicle dynamic simulation model including the LSD system is established, and it also has the analysis of the effects on the LSD for vehicle dynamics stability. Viscous Limited Slip Differential (VLSD) has influences on the motion characteristics of the vehicle in many aspects, including vertical movement and lateral movement that is most remarkable. It is obvious to improve the dynamic property and trafficability by it on the bad road for cars in longitudinal motion, but at the same time it also produce a great impact on the lateral movement characteristics of the automobile because of the unequal distribution of vehicle driving force.
