The Kinematic Simulation Analysis of The Mechanical Locking Ifferential

Based on theoretical prototype technology,this article take mechanical lock-up differential of dune buggy as example to make kinematics simulation analysis for self-lock and unlock of differential lock-up system under special condition.The analysis result had a better guide work for improving mechanical transmission system kinematics performance and key parts design.It also provides new study method for getting major gear load and fatigue lifetime estimation.At the same time,it provides basis for optimal design of dune buggy differential.
