Abstract
In this paper analyzes the stability and convenience vehicle, determined by how its suspension, wheel and finishing from the driver's seat, made his leadership ability in all road conditions or weather-climate. Thus the vehicle suspension, as the linking ground and its body body, so that taking over and share all the interaction forces and movements of the wheel with the road, has a role in acquisition, transmission and filtering them, which in ultimately turns into creating awareness of driving comfort. Study using the model of the car with two degrees of freedom and analytical method for assessing the quality of vehicle suspension, frequency response and root mean square response system were obtained indicators for assessing the sensitivity factors for excitation system external and mode of transmission. Also, the analysis of this model study, we obtained information on the area of εstability, determining the alteration of the mass distribution coefficient suspended, once determined its position on the surface of the car, suspension parameters were analyzed and their interdependence response to changes in function of the system to internal and external disturbance, analyzing the response curves represent three-dimensional functions, as seen in this link is better and achieving maximum efficiency in the optimization of the characteristics of leadership.
