DEVELOPMENT OF SIMPLE HYBRID DRIVEN VEHICLE AND USE OF LAYERED TECHNOLOGIES IN PROTOTYPE PRODUCTION

Purpose of this paper is to present simple hybrid driven vehicle. Desire for a new kind of hybrid driven and ecologically acceptable vehicles led to the development of a new contemporary vehicle. Vehicle, capable of transporting two persons, is mainly driven by a human power and backed-up by an electro-motor. Suitably regulated, such a concept may bring a revolution in the city and suburbs transportation. Methodology used for vehicle design and production is based on modern CAD/CAM based with use of layered and rapid manufacturing technologies. For steering mechanism, an analytical mathematical background was used so that mathematically correct wheel path was achieved. In the course of the work, mathematically correct equation for steering mechanism was derived and later used for development of steering mechanism. Flexible torque regulation of the back-up electro-motor that enables us constant load regardless of terrain is also presented. With the project of hybrid drive vehicle, a concept of vehicle that can be ideal for city and sub city transport is presented. With flexible torque regulation, an adaptive exercise machine that can be used to exercise with desired load at any time during transportation is implemented. The whole vehicle presents a modern and ecologically acceptable transport solution, at the same time this is an instrument of simultaneous recreation as well as a mean of physical condition improvement. Paper presents development of cost efficient vehicle with some unique solutions, like Bowden cable steering mechanism and flexible torque regulation, and production with help of modern layered & rapid manufacturing technologies.
