Elastic device for suspending a vibrating structure on a rigid structure

The present invention relates to devices for suspending a vibrating structure on a rigid support structure, in particular for suspending an exhaust pipe of a motor vehicle on the body of the latter. This device comprises an elastic element designed to be stretched between two fixing members spaced apart from one another in a direction of vibration and which are linked to one another by two elastomer branches, these branches extending substantially in the vibration direction. A vibrating mass links said branches to one another. This vibrating mass is provided in the form of a ring enclosing the elastic element so as to form two stop zones located respectively in the vicinity of the two fixing members in order to limit displacements of the latter under traction.
