The Design and Performance Analysis of Friction Disk Type Limited Slip Differential

Aiming at the ability to adapt to different road conditions of limited-slip differential(LSD) in drive axle, by building the without preloading friction disk type limited slip differential mechanical model, We derive the theoretical formula of the locking differential coefficient of the theoretical formula of limited slip differential without preload friction disk from mathematical theory derivation, and fitted theoretical curves, Which can be used as reference for further studies on other limited slip differential. Experimental verification was applied to the designed drive axle, experimental results shows that, the actual performance parameters of each drive axle design values consistent with the theory, to prove the correctness of the theoretical derivation, proved the correctness of theoretical analysis.
