Resumen
En este proyecto se desarrolla una metodología de diseño para un sistema de transmisión manual, adaptado a 6 velocidades en un vehículo automóvil, el KIA CEE’D 2022. Para ello, se obtuvieron de su ficha técnica los datos de la transmisión para las velocidades y de las revoluciones y potencia del motor a par máximo. A partir de estas relaciones de transmisión, se dimensionó el número de dientes de los engranajes y el resto de parámetros necesarios Se calcularon también los árboles de la caja de cambios, los rodamientos, las chavetas y el estriado de los ejes.
Además, para una de las piezas, se ha modelado en 3D utilizando el software CATIA. Se han extraído los planos de los componentes no comerciales que se han calculado y diseñado específicamente para este proyecto.
In this work not only a project is developed, but a full design methodology for a manual gearbox transmission system. The role model for this survey is the KIA CEE’D 2022, customized to a six speeds system. From the technical specifications of the vehicle, we obtained all the parameters for the speeds that had been calculated, and also all the revolutions, the relations and the power provided by the engine at peak torque. With all this information, using the speed ratios, the gears were dimensioned according to the teeth need to each. The transmission shaft was also parameterized, and we designed the remaining parts: bearings, splines... In addition to the mathematical calculations, it has been done a 3D model for each piece using the Software CATIA. Eventually, all the non-commercialized components that had been designed for this project were sketched out
