AIR SPRING ASSEMBLY AND METHOD TO PRODUCE IT Russian patent published in 2010 - IPC F16F9/04 

FIELD: machine building.

SUBSTANCE: proposed air spring assembly comprises first end element with sidewall and second end element spaced apart from the first element. Flexible hose has a wall and opposite open ends attached to said first and second end elements. First and second clamping elements are used to clamp one open end on appropriate end element. Method of producing air spring assembly comprises fitting flexible wall on first end element, fitting first clamping element and fixing flexible wall, fitting second section of flexible wall, fitting second clamping element and fixing flexible wall and first clamping element on first end element. Fixing second open end of flexible wall on second end element. In compliance with the first version, flange is arranged along first end element or first clamping element, and pressing the section of second clamping element inward. In compliance with the second version, flange is arranged along the first end element so that the flange extends inside beyond the outer edge of first end element, or beyond the first clamping element edge.

EFFECT: higher tightness, possibility to use springs at higher pressures.
