Diseño y construcción de un frenómetro para determinar la eficiencia del frenado en motocicletas según la Norma Técnica Ecuatoriana NTE INEN 2558.

Abstract

The present research was carried out with purpose to make a design and construction and contribution of a brake tester to determine the braking efficiency in motorcycles from load cells for weight and, braking tester of the motorcycle, programmed in the software Lab VIEW (Laboratory Virtual Instrument Engineering Workbench). The machine was manufactured under parameters mentioned at ETS (Equatorial Technical Standard), EIN (Ecuadorian Institution of Normalization) 2558 that brake tester must be rollers, tire diameters to be tested in brake tester and load applied on the motorcycle. The design and construction of each element applied brake tester applied theories of static, automation and machine design, the most critical parts of brake tester were checked with software SolidWorks. A jaw clutch with rectangular shaped teeth with truncated tips was built together with a cell type s and programming in LabVIEW allows to obtain the braking force of motorcycles. The rollers contained in the brake tester are responsible for rotating the rim of the motorcycle by means of geared motor, these rollers are coated with an elastomeric polyurethane that resembles asphalt called hardline 11-55, has high resistance to grinding and abrasion. With brake meter, it can obtain braking efficiency of motorcycles in circulation, which are being assembled in Equator and imported and thus reduce accidents of transits produced by brakes of motorcycles in poor condition or defective. Braking tests were carried out from ring from 13 to ring 19 and of several cylinders with which it can be concluded that brake meter is suitable for motorcycles that circulate in environment. For a correct operation and good operation machine it is recommended to use operations and maintenance manual.
