COMBINATION SUSPENSION Russian patent published in 1998 - IPC

FIELD: transport engineering; vehicle suspensions. SUBSTANCE: proposed combination suspension, as distinct from prototype, has hydropneumatic resilient member whose pneumatic part is provided with additional space and variable section throttle device installed before additional space and connected with power cylinder through high pressure pipeline and including movable disk in body of which regulating sectors and reactive channels for working fluid are made. Reactive channels are tangentially inclined relative to movable disk plane. Stops are fitted on end face of disk. It has also fixed disk on end face of which adjustable sectors and through slots for working fluid are made and left compression and rebound springs are installed for engagement with stops fitted on end face of movable disk. EFFECT: provision of optimum rate of combination suspension at considerably compression of gas in main pneumatic space of hydropneumatic resilient member and considerable speeds of displacement of piston rod of hydropneumatic resilient member owing to opening of additional space of hydropneumatic resilient member through variable section throttling device. 4 dwg
