Method and results of experimental determination of friction coefficients of some automobile brake shoe

Introduction . Road safety is largely determined by the technical condition of vehicle, and especially control systems. The braking system one them. To improve its efficiency, various assistive electronic systems are now widely used. These vehicle through wheel mechanisms. Brake pads a constituent element friction-type brake mechanism. efficiency depends on quality, regardless presence auxiliary use with wide spread friction coefficients can have significant impact performance. Materials methods conduct experimental studies, methodology for conducting them processing data was developed, as well laboratory setup made. Arduino Uno R3 analog-to-digital converter used an instrumental component stand converting mechanical movements into signal. Results In accordance proposed methodology, four pairs were tested. As result data, it found that difference in values cause magnitude forces wheels from 8 to 19%. Discussion conclusions has stability during braking. One reasons this may be poor quality pad material or violation operating conditions. improved technique determining sliding makes possible obtain more accurate converter, reducing influence accuracy measuring instruments human factor.
