A process for manufacturing a heat-insulated uncoupling element as well as an uncoupling element itself are proposed, wherein the heat insulation is provided along the corrugated area of bellows. The heat insulation consists of a coating, which contains heat-insulating granular material. The mobility of the bellows is also ensured here after application of the heat insulation.

Process for manufacturing a heat-insulated uncoupling element and an uncoupling element, especially for exhaust gas lines of internal combustion engines

An uncoupling element shields against structure-borne sound, especially for the exhaust pipe of internal combustion engines in motor vehicles. The uncoupling element includes a bellows () made of metal and a ring-shaped damping element () made of a lightweight composite. The damping element has particle-filled hollow steel spheres inserted at least one end of the bellows between the bellows end and a continuing pipeline.
