Abstract:
The purpose of this work is to design and calculate a kart transmission under the technical regulations and homologation governed by the CIK-FIA federation for the KZ1 and KZ2 categories, seeking competitive performance compared to the teams registered in the championship. First, information is gathered to provide an understanding of the operation of the gearbox mechanism and its adjacent components, analyzing the transmission subassembly from a global perspective of the vehicle. Then, all the constraints imposed on the design by both the competition authorities, as well as by the team itself and the race venue are outlined. The author then presents a study of the vehicle's longitudinal dynamics, offering a simulation whose results allow for comparing the different performances of competing transmissions with the gear ratio chosen for the project's gearbox. The calculation, sizing, and design of the components that make up the six-speed sequential transmission mechanism continue, ensuring the durability of each link to operate throughout a full season of the category. Finally, the project is consolidated with the desired performance.
