Abstract

In this study, the effects of rear axle and suspension modifications on the dynamic behavior of an extended midibus were analyzed. Modifications included an increased rear track width, achieved using a patented distancer system, and the integration of additional air and leaf springs. These changes were designed to enhance lateral stability, load distribution, and handling performance. A rigid-body vehicle dynamics model, validated through experimental testing, was used to evaluate the impact of these modifications under steady-state cornering conditions. The results demonstrated that the wider rear track and improved suspension geometry significantly reduced roll angle, enhanced yaw stability, and improved maneuverability. These findings provide a practical framework for optimizing stability and handling in extended vehicle configurations, contributing to safer and more dynamically robust midibus designs.
