Desenvolvimento de um sistema eletrônico automatizado para talonamento de pneus sem câmara em bicicletas

Abstract

This work presents the development and validation of an automated electronic system to assist in the seating of tubeless bicycle tires. The problem addressed is related to the difficulty of seating tubeless tires using only conventional pumps or common compressors, since this process requires a rapid and controlled release of compressed air to ensure the proper seating of the tire beads on the rim. In addition, there is a limitation of specific, portable, and automated solutions aimed at this application, which motivates the development of a functional prototype. The objective was to develop a system capable of controlling pressurization, compressed air release, and pressure monitoring during the process. The system consists of a compressed air reservoir, a 12 V compressor, two solenoid valves, two pressure sensors, an Arduino Nano microcontroller, an LCD display, a rotary encoder, and auxiliary power supply, actuation, and safety components. The methodology involved the initial validation of the operating principle, component selection, pneumatic and electronic assembly of the prototype, sensor calibration, and bench testing. The operation of the solenoid valves, pressure sensors, compressor, electrical power supply, and load actuation through relays was verified. Practical tests demonstrated that the prototype was able to pressurize the system, control the release of compressed air, and seat tubeless tires under real test conditions. The results obtained indicate the technical feasibility of the developed solution as a functional prototype for application in bicycles. [resumo fornecido pelo autor]
