<p>An improved air-spring with a diaphragm (20) fixed to a closing element by overlapping fitting, wherein the diaphragm (20) is made of rubber or any other synthetic material similar to rubber, it is provided with a strength carrier insert and it has on one or both ends flanges (20a) reinforced with steel wire or any other suitable wire. In order to provide an air-spring construction with exchangable diaphragm, to prevent back-slide in course of use, to achieve a proper airtightness and to reduce production costs on one or both ends of the diaphragm (20) the closing element is a cylinder-symmetrical flange-disc (19), made of sheet-material processed expediently by the technology of sheet-deformation, which is subdivided into sections promoting assembly with introductory continuously increasing and thereafter reduced local diameter, furtheron an impact surface (21) is provided for to assure proper positioning and airtightness of the diaphragm (20), while the latter one with the part of the flange-disc (19) with a reduced diameter thereto, as well as with the properly positioned diaphragm (20) confines a closed annular space-part (22) on three sides.</p> |
