Wheel suspension system for vehicle - has first stage with stiffness double stiffness of second stage to improve damping properties

摘要

The vehicle suspension system has first (230) and second (240) stages arranged behind each other in series such that the first stage of the suspension (20), the stiffness of which is more than double the stiffness of the second stage, is formed by an elastic mechanism (231) with a high degree of stiffness working with a damper (232). The second stage has a position drive (241) connected to a hydropneumatic reservoir (242) via a damper (243) having a damping effect more than double that of the first stage. ADVANTAGE - Improves ride comfort by filtering out high frequencies and strongly reducing the amplitude of the resonance frequencies.
