[0008] Although some of the above-mentioned patents involve the nonlinear variable stiffness adjustment of rubber-metal composite spherical hinges, it can be seen from the descriptions of these patents that the variable stiffness of the existing rubber-metal spherical hinges still considers the radial variable stiffness. The patent number is CN200510031727.7, and the invention patent titled "A Method and Product for Axial Precompression of a Combined Ball Joint-type Rubber Elastic Component" proposes axial precompression, but the actual consideration and concern are still The adjustment of radial stiffness, so the disadvantages of simply considering the nonlinear adjustment of radial variable stiffness still exist, so it still needs to be further improved

Abstract

The invention discloses an axial composite nonlinear variable rigidity adjusting method of a rubber metal spherical hinge. The variable rigidity of the rubber metal spherical hinge is adjusted throughadjusting the position relationship of a metal piece and a rubber piece of the rubber metal spherical hinge. The method is characterized in that the adjustment of variable rigidity of the rubber metal spherical hinge through adjusting the position relationship of the metal piece and the rubber piece of the rubber metal spherical hinge includes that the axial rigidity of the whole rubber metal composite spherical hinge is nonlinearly changed through adjusting the axial variable rigidity of the rubber metal composite spherical hinge. By adjusting the axial rigidity of the spherical hinge, the concept of providing nonlinear rigidity by the traditional spherical hinge in radial direction is completely changed, and a new design concept is brought to the design concept of the steering frame; the design concept of the steering frame is greatly widened, and the new possibility of the steering frame assembling structure is widened.
