Abstract An elastic engine mount with hydraulic damping includes a working chamber having an end, a compensating chamber, an intermediate plate disposed between the chambers having an annular channel formed therein interconnecting the chambers, a conical shell-shaped elastomer wall partially defining the working chamber, a bearing plate connected to the elastomer wall and bordering the end of the working chamber, a projecting cylindrical ring in the form of a tension and compression stop extending from the bearing plate into the working chamber and having an expanded free end in the form of an inwardly-disposed, radially-outwardly extending rim, a substantially cup-shaped stop ring gripping the expanded free end of the cylindrical ring, the stop ring having an axially-directed region with elongated radial through holes formed therein, and a rubber membrane disposed inside the cylindrical ring covering the cross section inside the cylindrical ring and closing off an air-filled membrane chamber.
Elastic engine mount with hydraulic damping, comprising a working chamber having an end, a compensating chamber, an intermediate plate disposed said chambers having an annular channel formed therein interconnecting said chambers, a conical shell-shaped elastomer wall partially defining said working chamber, a bearing plate connected to said elastomer wall and bordering said end of said working chamber, a projecting cylindrical ring in the form of a tension and compression stop extending from said bearing plate into said working chamber and having an expanded free end in the form of an inwardly-disposed, radially-outwardly extending rim, a substantially cup-shaped stop ring gripping said expanded free end of said cylindrical ring, said stop ring having an axially-directed region with elongated radial through holes formed therein, and a rubber membrane disposed inside said cylindrical ring covering the cross section inside said cylindrical ring and closing off an air-filled membrane chamber.
