Diseño e implementación del sistema de frenos respaldado en un sistema de recuperación de energía para un prototipo de vehículo tipo buggy hibrido 4x4.

Abstract

The objective of the present thesis work was to a adapt the bake system backed by a system for recharging the hybrid vehicle type buggy 4x4, which is the contribution recharged to the batteries of voltages of 96v. for the selection of this system the respective calculation were made based on braking force taking into parameters, such as the diameter of the breaking disc of 256mm and the rear 258mm, for the breaking forces in the front, was obtained 1555,7413(N) and the rear 1569,0436(N), optimal for the correct operation of the brake system. We used design software (Solid work), Analysis and simulations ANSYS workbench to analyze the thermal, dynamic and structural behavior. As for the backup system, the selection was established by the brushless three-phase HPC motor with a power of 15 KW, capable of moving the vehicle´ inertial of approximately 1000 kg. to carry out the test of the operation of the system, it was based on 4 test which are intended to verify the state of operation of the brake system, test one is based on calculating the braking distance and time at the different speeds, test two in the system pressure and tightness, test tree is the loading system using Hantek 1008C oscilloscope graph and test 4 explains the thermal behavior of the disc, with result obtained in terms of maximum temperature at the front 68,2°C and the back of 65,6°C, as well as the behavior of the thermal flux in the disc element pickle. From the above, before handing the vehicle use safety measure because this system works with the results obtained in the design formulas. Before manipulating the electronic system, and using the safety measures as high voltage gloves when handling connection cables, control modules or engine.
