ARTICLE HAVING SINGLE-LAYER OR MULTI-LAYER MAIN BODY, HAVING ELASTIC PROPERTIES, METHOD OF MAKING ARTICLE AND USE OF ALUMINUM HYDROXIDE AS ACTIVE FILLER IN RUBBER MIXTURE Russian patent published in 2024 - IPC B60G11/27 B32B25/04 B32B25/02 C08K3/04 F16F9/05 

FIELD: machine building.

SUBSTANCE: invention relates to the field of products performing the function of damping vibrations, and can be used in the pneumatic elastic suspension element membrane, and/or the pneumatic elastic suspension element, and/or bearing damping element, and/or conical spring, and/or multi-sheet spring. Pneumatic resilient suspension element (100) has multi-layer main body (8), having elastic properties, wherein main body (8) has inner elastomer layer (3), middle functional layer (4) and outer elastomeric layer (6), layers (3), (4), (6) are made from the same rubber mixture, wherein the rubber mixture contains aluminum hydroxide as an active filler and the total fraction of all technical carbons in the rubber mixture is less than 5 wt.pts. per 100 wt.pts. rubber, layer (4) is made in form of frame (13), note here that carcass (13) comprises cord fabric (7) fitted in at least one layer (5) of elastomer base (9). Rubber mixture can contain chloroprene rubber as a starting polymer.

EFFECT: invention enables to create an article for use in vehicles, having improved operational properties, such as elasticity, shrinkage or oscillation characteristics.
