Fast and not furious

Abstract

Two projects sequentially made planed and constructed of a wheelchair-low-cost and a car to run at the academic Gravity Racing Championship. The intention of them is provide to the Brazilian market a more durable and cheaper standard manual wheelchair and a racing car to access for a wheelchair and its driver. They were designed in CAD program for product engineering (modeling in 3 axis). The mechanical elements of movements were bought and retrofitted to the innovative structures. As the racing car was a 4 wheels model, the steering was inspired in the same used in kart models and the breaks and wheels were cycling components. The loading and unloading system was made by the driver without assistance of anyone (a ramp helps the person to load the wheelchair in the car and the person set the ramp up for safety). The car was not equipped with any propulsion equipment because the championship rules admit only the influence of gravity. © 2014 Springer International Publishing.
