The model built in this paper not only can be used in the analysis of vehicle longitudinal dynamics, but also is helpful to the development of this kind of new type differential.

With a 7 DOFs vehicle dynamics model, a study on the effect of JA1020LSD torque-sensing limited slip differential on the handling and stability of a rear wheel drive vehicle is conducted.

This model describes that the difference of rotate speed of two axle of viscous couple and the working temperature of it is the main outside factors influencing the shear torque of VLSD.
