Riassunto analitico
The present thesis provides the developments of a redesigned in-wheel traction system for the racing electric scooter eSc S1-X, developed by YCOM and competing in the first e-scooter world championship.
Track tests and driver feedbacks highlighted a consistent lack of torque at wheels. For this reason, the main focus of this document will be the improvement of the longitudinal traction characteristics by increasing the torque output to reach the target value.
Spur gears will be adopted to accomplish this objective and a specific geartrain will be designed to be fitted between the wheel rim and the electric motor, thus realizing the so-called in-wheel system.
Alongside with the aforementioned target, others will be considered, both from a technical, technological and economical point of view.
At the end, a FE model will be set to verify the feasibility of the solution in structural terms and to assess the overall design.
