Implementación de un banco didáctico transparente de un puente diferencial posterior para comprobar las características tribológicas de los frenos para el laboratorio de la Escuela de Ingeniería Automotriz.

Abstract

This is an educational and experimental paper. The objective is to observe the differential system of brake operation, and make tribology testing, as a contribution to the Automotive Engineering School. The modeling and analysis of the banks´ systems were developed with ANSYS and Solid Works software, taking into account the different variables to enter. The material selection was performed according to the calculations and obtained results, the catalog and existing material in the market were considered for the selection, and for the frame construction a rectangular carbon steel tube ASTM A36 was used. Traditional techniques applied in steel structures construction were used, the bank complement consist of assembling mechanical elements such as; AC (Alternating current) motor, gearbox, drive shaft, differential and brake system. Finally the manufacturing process was performed to get an adequate surface finish. The tribology study and tests were satisfactory for the different materials in brake shoes, as well as the analysis of the weight the structure supports. In the electronic spreadsheet the calculus formulas were entered to get and efficient outcome. It is recommended to read the operational manual and personal safety.
