Diseño y construcción de un sistema de dirección para un prototipo eléctrico monoplaza

Abstract

The objective of this research work was to design and build a steering system using mechanical and computer tools for a single-seat electric prototype. Documentary research allowed the collection of bibliographic information such as international standards and guidelines for standardization, with a quantitative approach to the measurement and dimensioning of the different elements and components of the vehicle. In addition, a field investigation was applied in the design and manufacture of the steering system. The design was done through the computer- aided drawing software, Solidworks; and the manufacturing employed various processes such as cutting, turning, polishing, drilling, electric welding and painting with specialized machines and tools; The construction of parts and assembly was carried out in a mechanical workshop environment, also complying with individual and collective protection measures. The designed steering system was subjected to a structural analysis, obtaining a minimum deformation of 0.031 mm, a safety factor of 6.14 and a maximum stress of 40.73 MPa; and on the other hand, in the field tests an external turning angle of 17.02°, internal of 19.44° and a turning radius of 5 meters were determined. It is concluded that the designed and manufactured steering system is functional for the vehicle and guarantees the driver's safety while driving. It is recommended that the manufacture of parts and mechanical elements comply with the technical specifications standardized at the national level.
