ELASTIC DAMPENING PNEUMATIC MEMBER Russian patent published in 2002 - IPC

FIELD: pneumatic suspensions for transport facilities. SUBSTANCE: elastic dampening member consists if rubberized cord envelope in form of truncated sphere relative to cover by means of spacer by clamping its upper band between taper bearing surfaces of cover and spacer and relative tightening by means of nut screwed on threaded end of spacer extending outside through central hole in cover. Arranged in hollow bolt which is used for securing the piston with additional volume to envelope is valve disconnecting chamber at the end of compression stroke in going from release stroke to compression stroke under action of inertia forces applied to its shut-off member at change of direction of motion of piston connected with unsprung masses of suspension. EFFECT: possibility of dampening oscillations without hydraulic shock absorbers; simplified construction of pneumatic member; enhanced durability and stability of characteristics. 1 dwg
