Projeto de solução para transmissão dianteira em veículo mini baja

Abstract

This work presents the development of a front transmission system for a Mini Baja competition vehicle, designed to meet the specific needs of the Imperador team. The main objective was to create a mechanical solution that optimizes performance, reduces weight, and simplifies maintenance while adhering to the team’s budgetary and manufacturing constraints. Engineering methodologies, such as the QFD matrix and morphological matrix, were applied to identify customer needs and select the most suitable concept. The developed system uses a roller chain for torque transmission and a dog clutch mechanism for coupling and decoupling the front traction, ensuring efficiency and reliability. The project included the design and structural analysis of critical components, such as shafts, gears, and coupling sleeves, based on resistance and safety criteria, as well as computational validation through finite element analysis. The results demonstrate that the proposed system meets the performance requirements, with the potential to enhance the prototype’s competitiveness in events. The technical and economic feasibility of the project was confirmed, and the next steps include manufacturing and experimental validation. This study contributes to advancing engineering practices applied to the development of mechanical systems in highly competitive academic environments.
