Análise de um sistema de arrefecimento para um CVT de um veículo tipo Baja SAE

Abstract

This work presents the analysis and development of a cooling system for the CVT (Continuously Variable Transmission) of an OffRoad Baja vehicle, designed for the Baja SAE competition. Given the need to control the CVT temperature, which can affect the durability and performance of the components, the study proposed using computational simulations to determine the effectiveness of the proposed model in reducing temperature and to identify the best configuration for the cooling system. The simulations considered different air entry angles: 45º, 60º, 90º, and 120º. The results showed that the configuration with a 60º angle was the most effective, reducing the CVT pulley temperature from 205,23ºC to 83,51ºC, a 59.3% reduction. This configuration allowed for more effective cooling of the pulleys, which is crucial for safe operation and increased lifespan of the CVT components.
