In research field of alternative solutions to internal combustion engine vehicles, the Politecnico di Milano has developed a design and manufacturing project for an adaptable electro-mechanical kit intended to transform a city car with endothermic propulsion into a bimodal one, using existent technologies and innovative solutions. This project involves mechanical and electrical competences in order to develop a new transmission parallel to the current endothermic propulsion and its control system. This paper describes, in general, the developed procedure to obtain the final prototype. At first, the requirements and constraints to fulfil a standard transport urban cycle has been established and the vehicle to modify was selected, in this case the Fiat Grande Punto. Next, new components and the required space to their installation have been identified and specified, whilst mechanical components were designed and manufactured. Instruments of reverse engineering and virtual prototyping have been employed to carry out the geometrical models, simulations and layouts and to identify useful spaces in the vehicle. Finally, general modifications, installation of new components, implementation of control and data acquisition system, fine-tuning and check of specifications fulfilment have been carried out. A 30 km range working in electrical mode, with a top speed of 70 km/h, is assured with the developed kit. These results demonstrate the feasibility to implement a forward bimodal propulsion system into a commercial city car with a little invasive commercial kit, and now, the Politecnico is working at its industrialization and implementation to different models of city cars. Regione Lombardia (Regional government in Italy) has funded this project as an investigation oriented to find new solutions to sustainable transport and reduction of environmental pollution.
En el campo de investigación de los vehículos con propulsiones alternativas al motor de combustión interna, el Politecnico di Milano ha desarrollado un proyecto para el diseño y fabricación del prototipo de un kit electromecánico a instalar en un vehículo urbano comercial, mediante la aplicación de tecnologías existentes y soluciones innovativas. El proyecto involucra competencias de naturaleza mecánica y eléctrica para el desarrollo y gestión de una nueva transmisión paralela a la propulsión endotérmica. Este documento describe en manera general el procedimiento para la realización del prototipo final. Inicialmente fueron identificadas las características necesarias para cumplir con un ciclo urbano estándar y se seleccionó el automóvil a modificar, en este caso un vehículo Fiat Grande Punto. Con los requerimientos establecidos se procedió a la identificación y especificación de los nuevos componentes y de los espacios útiles para su instalación y se diseñaron y fabricaron los componentes mecánicos necesarios. Para la realización de los modelos geométricos se utilizaron instrumentos de reverse engineering y modelación virtual. Por Ultimo, se realizó el montaje de los nuevos componentes y la instalación eléctrica, se modificó el sistema electrónico de control del vehículo y se efectuaron las pruebas de verificación, donde se confirmó el cumplimiento de la autonomía eléctrica de 30 km y la velocidad máxima en modalidad eléctrica de 70 km/h. Estos resultados demuestran la factibilidad de la transformación de un vehículo de propulsión endotérmica a propulsión bimodal mediante la instalación de un kit poco invasivo. Actualmente se está trabajando en su industrialización y aplicación a diferentes modelos de vehículo urbano. Este proyecto ha sido financiado por la Regione Lombardia (Gobierno regional italiano) como un proyecto de investigación orientado a la búsqueda de nuevas soluciones para el transporte sostenible y a la reducción de la contaminación ambiental.
