Análisis, recuperación y mejoramiento de un sistema de suspensión hidroneumática en un vehículo Citroën GSA X3 del año 1982 tomado como banco didáctico.

Abstract

This project describes an analysis, recovery and proposal for improving a hydropneumatic suspension system belonging to Citroën GSA, model 1982, detailing the functioning and components of a hydropneumatic suspension. It was carried out a vehicle inspection after its acquisition, finding the car was deteriorated and lacking some parts, so we proceeded to recover the hydropneumatic suspension. It was elaborated a simulation model of the hydropneumatic system based on an appropriated software that helped to understand with a higher clearness the functioning of each one of the components. Due to the dreadful state of the drive system, it was proposed an improvement through an appropriated design program carrying out a hydraulic circuit to be joined to the axis of height correcting devices and controlled by an electric, so to enhance its efficiency. Results on the system proofs were contrasted to the set parameters of manufacturer handbook, through this it was determined the system does perform a suitable functioning. It was also analyzed the performance on road using a vehicle with a different suspension (McPherson), concluding that the hydropneumatic suspension system has better stability in comparison with the other one. In order to complete the project, it was designed maintenance plan which will keep the system in optimum functioning conditions, and finally laboratory practices manuals were elaborated which will support to the learning teaching process of students at Ingeniería Automotríz School.
