Abstract
In recent years, traffic congestion and reduction carbon dioxide has become traffic problems. Narrow tilting vehicle has been anticipated as a potential solution to the various traffic problems. For further improvement of Narrow tilting vehicle, we propose a new steering method with a free front wheel that mechanically follows the vehicle body tilting. In this study, we have investigated the effects on the motion of the vehicle by the design of the front wheel caster angle and trail. We used the simulation by multi-body-dynamics as the research method to investigate the effect of the front wheel caster angle and trail. From the results of the study, it was found that (1) the design of the front wheel caster angle can give a significant change to the vehicle turning radius, and (2) the design of the front wheel caster angle and trail affect vehicle steering angle under disturbance on the front wheel.
