Abstract: An anti-vibration device is disclosed comprising an anti-vibration support comprising first and second rigid frames connected together by an elastomeric body and a limiting cap which is snap fitted onto the second frame and designed to be fastened onto a receiving member while clamping the second frame.

Abstract: Hydraulic anti-vibration support comprising first and second rigid frames interconnected by an elastomeric body which partially delimits an operating chamber filled with liquid, the second frame being fixed to a flexible elastomeric wall which partially delimits a compensation chamber communicating with the operating chamber via a restricted passage, the operating chamber and compensation chamber being separated from each other by a rigid partition fixed to the second frame. The second frame comprises first and second parts made from plastics material which are assembled to each other by rotary friction welding, and which are fixed, respectively, to the elastomeric body and to the flexible elastomeric wall.

Abstract: Anti-vibration assembly comprising an engine and a beam and an anti-vibration support for connecting the engine and the beam, damping vibration between the engine and the beam and supporting the weight of the engine in the vertical direction. The anti-vibration support comprises an inner armature and an outer armature which are connected respectively to the engine and to the beam. An elastomer body provides the connection between the inner armature and the outer armature. The outer armature forms a casing in which the inner armature (5) is force-fitted.

Abstract: 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.

Abstract: An elastic mount for a vehicle engine including an outer armature (1) intended to be connected to the engine, an inner armature (2) intended to be connected to the body (4) of the vehicle, and arms (5) made of elastic material connecting these two armatures together. The elastic material is bonded to the inner armature via the respective ends, of the arms the inner armature thus is radially covered with the elastic material. The two armatures have respectively complementary bearing surfaces capable of interacting so as to maintain the mutual centering of these two armatures in the axial direction in which the bearing surfaces are nested together as long as the mount is not subjected to the load of the engine. This interaction and the maintaining of centering are both automatically eliminated as soon as the mount is loaded by the engine.

Abstract: The invention relates to a hydraulic vibration-damping mount including a first rigid reinforcing member (1) and a second rigid reinforcing member (2), an elastomeric body (3) which includes, on the one hand, a thick wall (4) joining the two rigid reinforcing members to one another and partially delimiting a working chamber (A), and, on the other hand, a thin wall (5) which partially delimits a compensation chamber (B) connected to the working chamber by a narrow duct (C), the two chambers and the narrow duct being filled with a liquid, the second reinforcing member being a plate one face of which is secured in leaktight fashion to the elastomeric body in order to delimit, together with the latter, the two chambers and the narrow duct, the thin wall substantially exhibiting the shape of a bell only the edge (5.sub.1) of which is secured to the second reinforcing member.
