Caracterización del convertidor de par y su influencia sobre el desempeño del vehículo e implementación de instrumentación y visualización de variables principales de operación para la carrera de Ingeniería Automotriz.

Abstract

The torque converter into the automatic drivetrain has been quite important as well as the hydraulic clutches due to the capacity of amplifying the torque highly accurate over 98% of low RPM, working as attachment of 1:1in high RPM, to get a better efficiency and low gas intake for saving the environment. Because of its desing and fuction, the torque converter engages and disengages automatically the power of the engine to the gear, focusing on the engine RPM. With the powertrain on, at an idling speed, the power is weak due to the lack of fluid flow; However when speeding up, the powertrain gets stronger through the torque converter job. This research aims on the torque converter features based on the main variables. The first one was a test on the dynamometer for finding the torque and power curve, and the second one, an intake test. This study was made at CCICEV in order to understand how the torque converter works in automatic vehicles. A didactic board was built for seeing the torque graphics, power and slippery of the converter in order to verify possible damage in advance. This research was pretty important for the Automotive Engineering students from the Mechanics Faculty.
