Abstract
A hydraulic antivibration mount comprises two rigid tubular endpieces (1, 2) one surrounding the other, the endpieces being connected together by an elastomer body (3) shaped so as to form together therewith two diametrically opposite liquid-tight pockets (A, B) that communicate with each other via a narrow channel (7), said pockets and said channel being filled with a damping liquid, the narrow channel (7) being delimited on the outside by the inside cylindrical face (10) of the central portion of the inner tubular endpiece (1) and being delimited on the inside by a groove (8) formed in the outer cylindrical face of a ring (9). The inner tubular endpiece is shaped so as to present both an axial inlet (13) that is large enough to provide access to the ring (9) and a cylindrical housing (10) at the end of said inlet and suitable for receiving said ring as a force-fit.
