[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 pa

Embodiment 1

[0033] It can be seen from the accompanying drawings that the present invention relates to a traction ball joint, which is composed of rubber and metal materials, including a metal sleeve 1, and is press-fitted in the metal sleeve 1 and is composed of rubber and metal materials. The rubber metal vulcanized body 2, the rubber metal vulcanized body 2 contains a radial variable stiffness adjustment device 4 and an axial variable stiffness adjustment device 11, through which the radial variable stiffness adjustment device 4 and the axial variable stiffness adjustment device 11 adjust the rubber metal The radial stiffness and axial stiffness of the composite ball joint make the stiffness of the entire rubber-metal composite ball joint change non-linearly.

[0034] The axial variable stiffness adjustment device 11 is divided into two parts, one part is the variable stiffness adjustment device 6 with small axial stiffness, and the other part is the high stiffness non-linear variable s...

Embodiment 2

[0043] The implementation principle of the second embodiment is the same as that of the first embodiment, except that in order to further improve the effect of small stiffness adjustment, further processing is carried out on the small stiffness adjustment rubber parts. A rail transit non-linear variable stiffness traction ball joint, which is composed of rubber and metal materials, including a metal sleeve, and a rubber metal vulcanized body composed of rubber and metal materials is pressed into the metal sleeve through interference fit. The rubber-metal vulcanized body contains a radial variable stiffness adjustment device and an axial variable stiffness adjustment device. The radial stiffness and axial stiffness of the rubber-metal composite ball joint are adjusted through the radial variable stiffness adjustment device and the axial variable stiffness adjustment device. This makes the stiffness of the entire rubber-metal composite spherical joint change nonlinearly.

Abstract

The invention discloses a traction spherical hinge and a method for adjusting the nonlinear variable stiffness of the traction spherical hinge. Position relations between a metal component and a rubber component of the track traffic traction spherical hinge can be adjusted, so that the nonlinear variable stiffness of the track traffic traction spherical hinge can be adjusted. The traction spherical hinge and the method are characterized in that the adjustment on the nonlinear variable stiffness of the track traffic traction spherical hinge includes adjusting the radial variable stiffness and the axial variable stiffness of the track traffic traction spherical hinge, the radial variable stiffness and the axial variable stiffness of the track traffic traction spherical hinge can be adjusted,and accordingly the nonlinear variable stiffness of the integral track traffic traction spherical hinge can be adjusted. The traction spherical hinge and the method have the advantages that the axialvariable stiffness of the traction spherical hinge can be adjusted, ideas of radially providing nonlinear stiffness to the traditional spherical hinge products are completely changed, novel design ideas can be brought to design ideas for bogies, design philosophy for the bogies can be greatly expanded, and the possibility of novel bogie assembly structures can be developed.

Description

technical field [0001] The invention relates to a method and product for varying stiffness of rail vehicle components, in particular to a method for adjusting nonlinearly variable stiffness of traction ball joints of rail vehicles and a ball hinge, the method for adjusting nonlinearly variable stiffness of traction ball hinges and ball hinges The radial and axial rigidity height non-linear adjustment of the ball joint can be realized at the same time, thereby providing 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 rub...
