Rediseño de un disco de frenos normal a ventilado mediante mecanizado para la comparación de la eficiencia con otro disco convencional.

Abstract

The objective of this study is to redesign a normal to ventilated brake disk to compare temperature differences with another normal brake disk, to achieve this purpose a temperature monitoring system was installed in a Chevrolet D-Max vehicle which consisted of in the implementation of two temperature sensors located near each disk and a data acquisition card. The study of brake systems and disks makes it clear that the phenomenon of heat transfer caused by the friction of the disc and brake pads is of a nature that is to say varies over time, with the implementation of the ventilated disks it was possible to reduce the temperature generated by the friction of the braking, the heat dissipation of the disks is conducted by conduction towards the components of the brake system and by convection towards the environment. it was made monitoring of temperature values that occur between the disks and balatas at the time of braking was carried out, this is achieved through the monitoring system of temperature implemented in the present project. To obtain the temperature values of the brake disks, road tests were carried out with different types of disks: normal disks on the two front wheels, ventilated disks on the two front wheels and mixed disks. In mixed disks there is a normal disk in the front left wheel and a ventilated disk in right front wheel. Through real-time data visualization of the temperature in the brake disks it was concluded that the ventilated disks have a better thermal design since they have better ventilation and a lower maximum tension with respect to normal disks. From all the results of the route tests obtained, it was possible to visualize the temperature behavior in the disks at the time of braking, it was evidenced that the ventilated disks tend to heat up less than the normal disks, the redesigned disks are more feasible and efficient that guarantee a greater concentration of axial stresses at the time of braking.
