Abstract
A hydroelastic mounting for interpositioning between two assemblies to be suspended with respect to one another, for example in suspending an engine in an automobile, has its components arranged in the general direction of stress on the mounting. The components include a first armature, a working chamber defined at least partially by an elastomer block, and a movable diaphragm that delimits the working chamber. Movement of the diaphragm is controlled in the direction of stress. The components further include an expansion chamber delimited by the movable diaphragm and by a flexible membrane as well as a second armature linked to the elastomer block. The working and expansion chambers are at least partially filled by a liquid and are linked together by a communication passage. The mount also includes a deformable assembly which cooperates with the movable diaphragm to control displacements thereof. A control device applies a deformation force to the deformable assembly.
