1. pneumatic spring sub-mouth sealing mode;

  • Comprise upper cover plate, friction block, rubber pneumatic bag;

    It is characterized in that;

    on upper cover plate, have a flute profile breach;

    The breach of one band taper is also arranged on friction board, have the flute profile breach of upper cover plate and the breach of friction board to be combined to form a cone-shaped cavity that openings at one side is arranged, upper cover plate and friction board link together through fastening piece;

    The rim of the mouth part of rubber pneumatic bag is clipped in the middle by upper cover plate and friction block, and the rubber pneumatic bag rim of the mouth places in the cone-shaped cavity;

    The side of rubber pneumatic bag is drawn through the side openings of cone-shaped cavity, rubber pneumatic bag by opening therefrom mind-set extend outward;

    The last rim of the mouth of rubber pneumatic bag is monolateral cone-shaped;

    The flute profile breach of upper cover plate is " 7 " word shape;

    Breach on the friction board is the monolateral tapered indentations of outer circle;

    Be combined to form the cone-shaped cavity in the last rim of the mouth that rubber pneumatic bag is installed by the flute profile breach of upper cover plate and the breach on the friction board;

    The rim of the mouth part matches on cone-shaped cavity and the rubber pneumatic bag;

    It also is monolateral cone-shaped cone-shaped cavity;

    Their taperings are identical, but the last rim of the mouth of rubber pneumatic bag is bigger than upper cover plate and the formed cone-shaped cavity of friction board;

    The rubber pneumatic bag rim of the mouth is placed in the groove of rim of the mouth;

    Described rim of the mouth groove is combined to form by upper cover plate and friction board;

    The rubber pneumatic bag rim of the mouth places between upper cover plate and the friction board in the groove of formed rim of the mouth, and forms the sealing in rubber pneumatic bag rim of the mouth through the compression of the applying between upper cover plate and the friction board.
