  • Patent number: 9933036
    Abstract: A damping rubber spring for an automobile suspension, including: n rubber layers (2), n being a natural number not less than 3; n+1 metal partition layers (1) including an upper partition layer (4) and a lower partition layer (5), the n rubber layers (2) and the n+1 metal partition layers (1) being laminated alternately with each other, and the upper partition layer (4) being disposed in parallel with the lower partition layer (5), wherein an m-th rubber layer (2) starting from the upper partition layer (4) has a thickness or cross section area that is the same as that of an m-th rubber layer (2) starting from the lower partition layer (5).
    Type: Grant

  • Patent number: 9499022
    Abstract: An auxiliary rubber spring for an automobile suspension, comprising: N layers of metal partitions, N being an integer greater than or equal to 1, and a transverse section of each metal partition being arc-shaped; N+1 rubber layers, the rubber layers being alternately lapped with the metal partitions, and a transversal section of each rubber layer being arc-shaped; a supporting plate provided with a first convex arc surface on one side thereof, the first convex arc surface being bonded to a first concave arc surface of an outermost rubber layer; and a connecting plate provided with a second concave arc surface on one thereof, the second concave arc surface being bonded to a second convex arc surface of another outermost rubber layer. The auxiliary rubber spring for an automobile suspension according to the present invention may increase fatigue resistance of the rubber spring and effectively extend service life thereof.
