Primary Springs
chevron fjedre
GMT-Chevron fjedre er multifunktionelle vibrationsdæmpende elementer, hvor de enkelte metaldele holdes sammen med vulkaniserede lag af elastomer.
Chevron fjedre har en lang levetid og er nemme at installere, hvilket gør dem ideelle til tog.
Ved at vælge vinklerne og antallet af mellemfjederled samt vinklerne på Chevron fjedrene i forhold til hinanden, kan der fremstilles tre forskellige fjederstivheder afhængig af retningen. Endvidere kan stivhedsgraden også varieres ved at vælge de enkelte lags geometriske dimensioner og den tilsvarende gummikvalitet.
Primær Konusfjedre
GMT-Conical suspension springs are used e.g. as engine mountings, aggregate bearings and primary springs in railway vehicles. Being vibration insulators and dampers, conical springs allow a relatively considerable spring characteristic and have a progresssive curve. Buffers also help to absorb shock loads without causing damages to the part. If different degrees of stiffness are required in X and Y directions, uses elements with slots can be designed.
GMT-Rolling rubber-springs
GMT-Rolling rubber-springs are vibration dampening elements consisting of a rubber ring, a tapering metal pin and a metal housing. Their metal parts and the rubber ring are assembled by a special process.
Roller-springs are used for dampening vibrations in rail vehicles. The characteristics of roller-springs can be varied as required within their permissible capacity.
