Diseño y construcción de un sistema de freno hidráulico de pedales para un prototipo eléctrico monoplaza

Abstract

The objective of this technical project was to design and build a hydraulic pedal brake system for a single-seat electric prototype that must be light and effective, capable of controlling the speed of the vehicle. It began with the theoretical foundation of the hydraulic brake system, knowing its components and operating principles. The operation and effectiveness of the braking system were theoretically evaluated, and the prototype was analyzed on a 20% slope, obtaining a braking force of 255,619 Newton that is required to keep it completely stopped on this slope. The materials were selected based on the established requirements, which allow the speed to be controlled using a pedal and being able to stop by applying the brake on the front and rear axles individually. The design of the brake system was carried out using electronic tools specifically Solidworks. By using practical tools, the construction and assembly of the entire hydraulic pedal brake system were carried out to be implemented in the single-seater electric prototype, complying with the methodological process of the project. The behavior of the elements was evaluated using CAE software, simulating a load of 250 Newton to which both the pedal and the support of the brake actuation system are subjected. It is concluded that by activating the braking system individually for each of the axes, an optimal braking response is obtained, capable of completely stopping the prototype, and in turn, a braking distance of 3,351 meters is reached, evaluated at a speed of 40 Km/h, ratifying the correct functioning of the hydraulic pedal brake system. To keep the brake system in perfect condition, it is recommended to carry out maintenance every 6 months and periodically check that the tightening torque is adequate.
