AUTOMOBILE SUSPENSION SHOCK-ABSORBING RUBBER SPRING

摘要

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) located at an uppermost position of the damping rubber spring for an automobile suspension and a lower partition layer (5) located at a lowermost position of the damping rubber spring for an automobile suspension, 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). Advantageously, the thickness of a center rubber layer (2) is larger than those of other rubber layers (2), or the cross section area of a center rubber layer (2) is larger than those of other rubber layers (2). The thicknesses of the rubber layers (2) on the upper and lower sides of the center rubber layer (2) gradually decrease towards the upper partition layer (4) and the lower partition layer (5) respectively, and the cross section areas of the rubber layers on the upper and lower sides of the center rubber layer (2) gradually decrease towards the upper partition layer (4) and the lower partition layer (5) respectively.
