Study On Application Of Limited Slip Differential

Limited slip differential is improved according to common differential. Not having the common differential's disadvantage of dividing the torque into two equal parts, limited slip differential can give most torque or even all torque to another driving wheel which is not revolving in order to make use of the friction of this driving wheel to produce enough traction. This will greatly increase the dynamical capability, the passing capability, the stability and the safety of automobiles on different friction roads. So limited slip differential is substitute for common differential.In this paper, the advantage and the disadvantage of the differential and the limited slip differential are compared. The application of limited slip differential in the world is introduced. The principles and the types of limited slip differentials are discussed. Compared with all kinds of limited slip differential, the preload spring friction disc limited slip differential which is used as the axle bridge differential in a certain SUV is selected at last.Then the limited slip capability of the mathematical model of all kinds of the limited slip differential is put forward. The finite element analysis is used to analyze the static structure of the shell of the limited slip differential in three different working instances. It shows that the strength and the stiffness of the shell of the limited slip differential are satisfied.According to the fact, from several kinds of the limited slip differential's tests, one test is decided and the analysis of the test is expounded.
