Abstract

An electric vehicle is focused attention as a solution for solving the global environment issues. And if electric vehicle has exceeding performance than internal combustion engine vehicle and surpassed attractiveness, it will be accepted in the society widely. Tandem Wheel Suspension System (TWS) is a new suspension concept for electric vehicle that makes a great progress in space utility, handling ability and ride comfort. A general concept of TWS is replacing the 4 larger sized wheels with 8 smaller wheels. The four couples of adjoined two wheels are connected with the hydraulic piping and hydro-pneumatic spring shock absorber units. The results of simulations reveal that ride comfort of TWS should be improved 3.6 times compared with 4 wheels reducing the body vibrations and body pitching.
