Abstract
The paper shows the design of a steering system of a hydrogen fuel cell three-wheeled vehicle, starting from the constrains made by the Shell Eco-marathon, the competition to which it must participate.
In particular, the vehicle dynamics behavior has been analyzed using simulation software, analyzing different solutions of the steering system to choose, finally, the architectures that allows to be closer to the ideal kinematic conditions and to have a correct kinematic behavior for each working condition in terms of steering wheel angle.
Thanks to the results of the vehicle dynamics analysis the forces in longitudinal and lateral direction have been calculated and used to design the mechanical components (from the steering wheel to the wheel rim), to minimize the rolling resistance losses of the tires.
As an example of mechanical design, the case of the wheel hub, is reported.
