Projeto de um sistema de freio para um protótipo veicular do tipo Baja Sae

Abstract

One of the main systems of a car, the brakes, has the function of decelerating or stopping a vehicle ensuring the driver and passengers a safe braking under the most adverse conditions to which the vehicle will be subjected. Therefore, the present work has as objective the design of the brake system applied to the off-road vehicle type Baja SAE, which will be developed by the team of the Federal University of Ceará - Russas Campus. First, to carry out the project, the necessary information for the calculation memorial, a familiarization with the content were collected and some of the components that will be used were selected, later a Python algorithm was designed for sizing according to the bibliography. After performing the calculations in the program it was possible to reach a mechanical pedal extension of 4.51: 1, and from this information design the vehicle pedal to meet the needs of efforts and ergonomic for any type of passenger. It was also simulated the efforts imposed on the pedal and the disc, and through the simulations it was found that they resisted the efforts with a safety coefficient of 3.1 and 3.23 respectively. After sizing the system components it can be concluded that they were in accordance with the safety standards of the Baja SAE Brazil Project and presented values within the ranges suggested by the bibliographic references.
