[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

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.

Description

technical field [0001] The invention relates to a rail vehicle component product, in particular to a rubber-metal composite ball joint. The rubber-metal composite ball joint has the characteristic of axial nonlinear variable stiffness, and can realize the radial and axial directions of the ball joint at the same time. The stiffness height is non-linearly adjusted, thereby providing the bogie design with the installation possibility of realizing the longitudinal bearing by the axial direction of the ball joint, which belongs to the technical field of rail vehicle manufacturing. Background technique [0002] The rubber-metal traction ball joint is a kind of rubber-metal composite ball joint, and it is also one of the key components for the transmission of traction and braking force between the locomotive body and the bogie. Most of the adjustments use rubber and metal composite parts. This rubber-metal traction ball joint is lighter in weight and can achieve flexible traction ...
