VEHICLE SUSPENSION PNEUMOHYDRAULIC SPRING Russian patent published in 1998 - IPC

FIELD: transport engineering; pneumohydraulic springs with self-adjustment of hydraulic resistance depending on vibration frequency. SUBSTANCE: purpose of proposed pneumohydraulic spring of vehicle suspension is provision of automatic two-stage changing of rigidly of damping characteristic depending on vibration frequency of sprung and unsprung masses owing to new cycle of operation of damping unit increasing efficiency of vibration damping in resonance zones and without increasing vibrations in non-resonance zones. EFFECT: improved smoothness of riding and road holding capacity of vehicle. 3 cl, 2 dwg
