METHOD OF MANUFACTURING ELASTIC ELEMENT OF VEHICLE AND ELASTIC ELEMENT OF VEHICLE Russian patent published in 2020 - IPC B60G21/55 

FIELD: transportation.

SUBSTANCE: invention relates to automotive suspensions. Elastic element comprises rod-shaped and rubber element provided on fastening part of rod-like element, and adhesive provided between glued and attached surfaces of rubber element. Rod-like element includes first and second parts from steel material and film coating. In the first part angle of contact with water exceeds 65°, in the zone, which does not include the fastening part of the surface of the film coating. Second part includes the smallest uneven sections, at which the maximum height of micro irregularities of the surface profile and the wavelength are small compared to uneven sections of the first part. Method of elastic element manufacturing includes formation of rough surface and film coating from resin, change of contact angle of glued surface to 65° or less, coating of uncured liquid adhesive on rubber element or fastening part. Further, the fastening part is closed by the rubber element and the adhesive hardens.

EFFECT: achieving strong bonding of the rubber element.
