Design and simulation of the cardan for the power system of the BAJA SAE UAM 2023 vehicle

Abstract

In this article, the requirements and design of a driveshaft for the implementation of a 4X4 transmission system are presented. Vehicles equipped with this power transmission system are of great interest because they can overcome challenging terrains. The implementation will take place in the ESCUADRÓN UAM 2023 vehicle, as the regulations for the BAJA SAE 2023 competition require a 4X4 powertrain. Furthermore, the article provides a focused view of the challenges and practical considerations that arise when building a single-seater vehicle for BAJA SAE. All new elements for power transmission to the front axles must be designed, including the driveshaft, a crucial component serving as the transmission link between the parallel axles of the vehicle, whether continuously or not. For the design of the driveshaft, forces to be transmitted were calculated, followed by material selection and subsequent simulation, considering the motor output and speed reductions that occur before the driveshaft. This article aims to obtain the final driveshaft design for subsequent implementation in the vehicle for the BAJA SAE MÉXICO 2023 competition.
