Diseño y construcción del sistema de transmisión eléctrica y suspensión delantera del vehículo hibrido tipo Buggy 4x4 para la Carrera de Ingeniería Automotriz de la ESPOCH.

Abstract

The objective of the titling project is to design and build the electric transmission and front suspension system in the hybrid 4x4 prototype for the automotive engineering career. In the first instance, information was collected and analyzed regarding hybrid vehicles and their electrical transmission systems in where the parameters that must be met by the electric transmission train are determined. Based on the calculation methodology and using formulas established for the selection of electric motors, the required motor power of 15 kW and a required torque of 286.7 Nm required for drive the prototype and using the weighting method we choose to acquire the DC motor and controller manufactured by the company Golden Motorbikes, in addition to the design of the structure we select an independent suspension system type McPherson, which was designed by means of of SolidWorks software plus the elements Fixing cords are subjected to stresses which are analyzed by Ansys software, which showed us a safety factor of more than 15. By carrying out the respective functional tests, the electric transmission system and front suspension incorporated in the hybrid prototype did not present any nonconformities, and there is stability in its conduction, which is why it is considered that the selected elements and designed mechanisms are the ones suitable for the prototype, but it is recommended to continue with the study of the mechanical transmission in order to improve the prototype and obtain greater speed and autonomy.
