Dimensionamento de uma pinça de freio a disco para veículo de competição tipo Baja SAE

Abstract

The present work aims to show the line of reasoning and the steps for sizing the front and rear calipers (brake calipers) for an off-road prototype car of the Baja SAE type. The application of this project encompasses racing, high-performance vehicles, and competitions. The braking system is of utmost importance for any vehicle, being the primary safety system. It needs to ensure its functionality, be reliable, safe, and guarantee the pilot's safety; in other words, the braking system needs to be fail-proof. In the present work, all data were obtained through tests, literature, and experimentally, with tests conducted by the team. The sizing was done aiming for a final product capable of generating the vehicle's deceleration according to the speeds reached. Analytical calculations for the correct sizing of the vehicle's calipers will be addressed, also presenting the calculation record in Excel spreadsheets and the manufacturing and assembly drawings.
