Riding Performance of a Vehicle with a New Type of Hydro-Pneumatic Balanced Suspension

Following the characteristics of ordinary hydro-pneumatic balanced suspension in which the cylinders are installed vertically, a new type of hydro-pneumatic balanced suspension where the cylinders are installed horizontally is designed. Two types of multi-spindled hydro-pneumatic balanced suspension mathematical models were built up and solved with Matlab to compare the performance of the new hydro-pneumatic balanced suspension with the conventional suspension. The result indicated that using such suspensions, the vibration performance of vehicles is improved, the price is reduced and reliability of the suspension system much improved. The new suspension is more suitable for use in multi-spindled vehicles.
