    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.

    专利说明:

    The invention relates to mechanical engineering, namely to pneumatic springs.
    The purpose of the invention is improving the reproducibility by simplifying the installation of a flexible shell.
    FIG. 1 shows a pneumatic spring, longitudinal section; Fig. 2 shows a mounting unit for a flexible shell on a support element, a longitudinal section.
    The pneumatic spring contains support elements 1, on at least one of which on the inner side there is fastened washer 2 fitted from the bead, mounted on the last flexible sheath 3 with a reinforcing insert and flanges 4 at the ends having metal wire elements 5, and has a closed annular cavity 6 formed by the supporting element I, the washer 2 and the flange 4 of the flexible shell 3. The flange flange 2 of the flange 2 is made conical with increasing in the opposite direction The diameter of an element is half the angle bЈ at the top of the cone is selected from a ratio of 7 °, and the height h of flanging is from the ratio h 2-4R, where R is the radius of curvature of the flanging, and the closed annular cavity 6 is filled with a sticky elastic material
    The device works as follows
    The flap-supplied washer 2 is welded or glued to the support element 1. The flexible shell 3 is installed by supplying pressurized air to the internal cavity of the air spring. The rubber edge of the flange 4 of the shell 3 is deformed, part of the flange 4 passes through the maximum diameter of the flanged washer 2 and enters in a closed annular cavity 6 Before mounting the shell 3 closed annular cavity 6 on
    70% is filled with a sticky elastic material (for example, a raw rubber compound). 3 bonding force
    with metal elements can be increased by vulcanization, which also contributes to improving the air permeability of the device. When performing repair work using
    The assembled flexible sheath 3 is cut off and the filler is removed from the closed annular cavity 6, after which the supporting element 1 and the flanged washer 2 can be used
    is brilliant.
    When applying a dynamic load to the support element 1, an elastic force is created due to the compression of air, hermetically enclosed in
