Spring device, particularly coil spring for chassis suspension of motor vehicle, has metallic spring body wounded up in turns, and coating is made up from elastomer, silicone or silicone-coating elastomer material

摘要

The spring device (1) has a metallic spring body (2) wounded up in turns. The spring body limited on one of its connection area or end area has a pressure-proof or abrasion-proof coating (3), where the coating is made up from an elastomer, a silicone or a silicone-coating elastomer material. An independent claim is included for a method for coating a spring device by applying coating of an elastomer, a silicone or a silicone-coating elastomer material in the immersion process.
