Reingeniería de los sistemas de dirección y de frenos del automóvil Land Rover Hard Top del año 1981 para taller móvil de la Escuela de Ingeniería Automotriz.

Abstract

Reengineering of the steering and brakes systems of the Land Rover Hard TPO vehicle, year 1981, for a mobile mechanics service from the School of Automotive Engineering, aims to make useful a good which will be implemented by phases in order to provide road maintenance services.The study begins with the general diagnosis, where it was determined a significant deterioration, and a lack of important parts that had to be replaced. Prior to the placement of its part and spare parts, it was gathered technical information of each component and operation systems as the steering consisting of a casing, a hydraulic pump, steering swivels and the pulley that is the source of the engine power being this way how it activates. The brakes mechanism was a drum brakes system and now it is formed by a disc brake system in which a re-engineering that made possible to improve the efficiency and effectiveness of these systems was applied. The simulation of the steering movements and brakes of the vehicle were analyzed by using computational methods, stop time calculations, distance and temperature produced in the disc brakes followed by complementary practical test operation check.The outcomes obtained in the steering system reveled and efficiency between the range of 28,2% to 33,3% compared with the previous mechanical steering providing more comfort and safety to the driver; as well as the brake system shows less overheating and more efficiency at breaking.The rehabilitated vehicle by means of the studied systems, possess maintenance as well as the user’s manual to be used correctly, so this vehicle will be a useful good as long time as possible.
