Anti-Vibratory Support For A Motor Vehicle And Motor Vehicle Equipped With Same

The invention relates to an anti-vibration support, comprising first, second and third frames, which are metallic, accessible from the outside and separate from one another, at least one part made of elastomer. The invention is characterized in that the support also comprises a member made of thermoplastic material comprising at least one reinforcement, which has continuous-fibers and which is a prefabricated part, to reinforce the mechanical strength of the anti-vibration support, the first and second frames being far from one another in a first, substantially horizontal, direction, are intended to be fixed to a body of a motor vehicle and are connected one to another by means of the member made of thermoplastic material, the member made of thermoplastic material being over-molded with respect to at least a portion of at least one surface of the reinforcement, with respect to first and second surfaces of the first and second frames and with respect to at least one surface of the part made of elastomer supporting the third metal frame intended for the suspension of a vibrating portion of the vehicle, for damping and filtering mechanical vibrations between the body and the vibrating portion.
