Simulação virtual de sistema de transmissão CVT baseado em benchmarking

Abstract

The present work is the proposition of a transmission arrangement, based on already consolidated systems in the Mechanical Engineering. Due to the characteristics of the use of the motor torque and the simplicity of the system, a CVT (Continuously Variable Transmission) transmission was developed. By knowing the components applied in the general transmissions and the elements of the CVTs transmissions, the concept of Benchmarking was applied, which boils down to taking advantage of the best of each idea. The proposed model consists of two pairs of variator pulleys where one pair is connected to the motor shaft and the other pair is connected to a planetary system that transmits the final drive ratio. To simulate the system was used the computer software CAD (Computer Aided Design) SOLID WORKS, taking as reference of loads, torque and power of a standard engine of a vehicle Baja SAE. The results of final tensions of each simulation module are presented and compared to the Yield Strength of the materials present in the modules.
