A hydroelastic mounting to be interposed between a first, vibrating element to be supported and a second, load-bearing element to be insulated, the mounting comprising: a body (10) comprising a rigid upper portion (30, 150) and a rigid lower portion (110) which are connected by a mass (50) of resilient material, the upper portion being intended to be connected to the element to be supported, a casing (20, 40) which is intended to be connected to the load-bearing element and forms a housing (204) for the body (10), and damping means (60, 70, 80; 212; 501-504) for damping the movements of the upper portion (30, 150), the damping means comprising a main working cavity (60) and at least one auxiliary cavity (70; 212) which communicate, are filled with liquid, and are provided with resiliently deformable walls (501; 502; 503, 504). The body (10) is formed as a cover which is coupled with a base portion (20) of the casing (20, 40) in a manner such as to close the cavities (60, 70; 212) hermetically. The lower portion (110) of the body (10) is coated by a portion of the mass (50) of resilient material which forms the deformable walls (502; 503, 504) of the at least one auxiliary cavity (70; 212) integrally. <IMAGE> |
