Abstract

La présente invention concerne un caoutchouc de suspension et, plus spécifiquement, un caoutchouc de suspension, qui fixe un tuyau d'échappement disposé sur la surface inférieure d'un véhicule à la carrosserie du véhicule, et empêche la déformation de l'élément de suspension due à un impact pendant le déplacement tout en isolant efficacement la vibration générée dans le tuyau d'échappement. Comme décrit ci-dessus, selon la présente invention, la vibration et la déformation de l'élément de suspension sont supprimées, de telle sorte que la transmission de la vibration et du bruit du tuyau d'échappement à la carrosserie de véhicule sont efficacement réduites, et un phénomène d'interférence entre le tuyau d'échappement et la carrosserie de véhicule, provoqué par un impact important pendant le déplacement, peut être empêché de telle sorte que le confort de conduite des passagers et l'attrait commercial du véhicule peuvent être améliorés.
