Abstract: This paper focuses on the design and optimization of a four-wheel drive (4WD) transmission system for Baja racing vehicles operating in complex off-road environments. By analyzing the typical working conditions and performance requirements of Baja vehicles, an integrated system design scheme combining the main reducer and limited-slip differential is proposed, encompassing the layout of transmission routes and mechanisms, as well as parameter selection and structural design of key components. Based on the vehicle design parameters of the Baja car, the transmission ratio of the main reducer is preliminarily determined and further optimized using OptimumLap software to achieve optimal performance. Finite element analysis through ANSYS software is conducted to simulate and validate the reliability of critical components such as gears and reducer housings. This research provides valuable reference for the design and optimization of transmission systems in Baja racing vehicles.
