Designing and characteristics analysis of electric suspensions with symmetrically arranged two slider-rods

An innovative design of electric suspensions was developed in this study to help realize slow active suspension easily and quickly. This design was driven by screw through double slider-rod arranged symmetrically as a substitute for two springs. Based on a mathematical modeling, suspension parameters were introduced for a certain type of wheeled vehicles. The functions and its mechanism in regulating terrain clearance and adjusting attitudes were subsequently explained respectively, together with its semi-active control mechanism and characteristics In conclusion, our data in the study show that the new mechanical design of suspensions not only could realize adjusting terrain clearance and static vehicle pose, but also had an ideal stiffness that could realize a semi-active suspension function through adjusting suspension's stiffness. Therefore it can bequite suitable for off-road wheeled vehicles and military wheeled vehicles.
