Diseño modular del sistema de transmisión de potencia de un gokart eléctrico de competencia con chasis modelo D.A.

Abstract

The design of a modular transmission system for an electric competition go-kart optimized its performance and efficiency by comparing two configurations: with and without a gearbox (reduction ratio of 3.78). This study evaluated the inclusion of the gearbox on the vehicle's energy consumption, autonomy, and mechanical stability under racing conditions. The motor with the gearbox reduced energy consumption by 40% compared to the motor without a gearbox, extending the autonomy from 360 km to 540 km with the same battery. The maximum current decreased from 300 A to 250 A and multiplied the initial torque, allowing for faster acceleration (0–110 km/h in less time). The D.A. model chassis withstood cyclic loads greater than 3,693 N without permanent deformation.
