Hydraulically damped unit bearing for mounting internal combustion engine of motor vehicle, has working space, which is sealed in gas tight manner against bearing body by soft pressure

摘要

The hydraulically damped unit bearing has a working space (20) and a damping fluid (22). The working space is sealed in a gas tight manner against a bearing body (16) by a soft pressure. The working space is limited by a membrane (24) forming damping fluid resistance. A chamber (26) is formed between the membrane and the bearing body. The chamber is filled with a fluid (28), particularly glycol. The bearing body has fluid resistant material properties. The two membranes are manufactured from fluorosilicone rubber or hydrogenated acrylonitrile butadiene rubber.
