A ring for fitting to a resilient support containing two metal cores interconnected by a piece of elastomer, the ring serving to limit the extent to which the cores can be moved apart accidentally. The ring is rectangular in section and is made up of a succession of alternating layers respectively constituted by tapes of elastically deformable material and by sheets of parallel threads that are strong in traction.

Limit rings for resilient supports and methods of manufacture therefor

The invention relates to a hydraulic antivibration support designed to be interposed between two rigid elements. It comprises a working chamber and a compensating chamber separated by a rigid partition and connected permanently with one another through a throttled passage. Both of these chambers and this passage are filled with liquid. The working chamber is composed of two compartments connected to one another through a throttled annular column bounded internally and externally by two cylindrical surfaces fast respectively to the two rigid elements.

Hydraulic antivibration support

The invention relates to an antivibration support to be inserted between the frame and the engine of a vehicle. The support comprises two deformable chambers filled with liquid, separated by a deformable partition, and communicating with one another through a restricted passage, namely an operating chamber whose lateral wall forms a support and joins two rigid parts fixed respectively to the frame and to the engine, and a compensating chamber. When abnormally high thrusts are applied to the engine, the deformations of the wall are limited by abutment, against a ring immersed in the operating chamber and borne by the first rigid part, of a central foot fast to the second rigid part, and passing with clearance through the ring and/or of an overlapping sole terminating this foot.
