Disclosed is a rubber-metal compound spherical hinge with axial nonlinear variable rigidity. The rubber-metal compound spherical hinge with axial nonlinear variable rigidity is composed of rubber andmetal materials in a compound mode and comprises a sleeve and a rubber-metal vulcanized body, which is pressed in interference fit inside the sleeve and composed of rubber and metal materials in a compound mode; the inside of the rubber-metal vulcanized body is provided with an axial variable rigidity adjusting device which can adjust the axial rigidity of the rubber-metal compound spherical hingeso that the axial rigidity of the rubber-metal compound spherical hinge can be changed nonlinearly. The axial variable rigidity adjusting device is composed of two parts including an axial small rigidity variable rigidity adjusting device and an axial high rigidity nonlinear variable rigidity adjusting device, which are combined to achieve axial nonlinear variable rigidity adjustment of the entire rubber-metal compound spherical hinge. Through axial variable rigidity adjustment, the rubber-metal compound spherical hinge with the axial nonlinear variable rigidity provides a nonlinear rigidityidea and accordingly brings about a new design idea for a bogie.
