Problems solved by technology

[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 a traction ball hinge axial nonlinearity rigidity adjusting laminated spring and an adjusting method. A metal sleeve is included, and rubber metal laminated spring bodies formed through compounding of rubber elastic bodies and metal are arranged in the metal sleeve. The traction ball hinge axial nonlinearity rigidity adjusting laminated spring and the adjusting method are characterized in that the rubber metal laminated spring bodies are axially arranged, and ball hinge axial nonlinearity rigidity changing is achieved through deformation of the axially-arranged rubber metal laminated spring bodies. The rubber metal laminated spring bodies are T-shaped rubber metal laminated spring bodies, and the sleeve of the T-shaped rubber metal laminated spring bodies is a T-shaped metal framework, and the laminated spring bodies are distributed on the two sides of the radial row width of the T-shaped metal framework and symmetrically distributed.
