[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

Embodiment 1

[0033] It can be seen from the accompanying drawings that the present invention relates to a spherical hinge with an axially variable rigidity of a ball hinge with an I-shaped bush and a laminated spring. It includes a casing sleeve 1, and a rubber metal The vulcanized body 2 realizes the nonlinear variable stiffness of the spherical joint through the deformation of the rubber metal vulcanized body 2; the rubber metal vulcanized body 2 is divided into two parts, one is an I-shaped rubber metal vulcanized body 4, and the other is a "T"-shaped Rubber metal vulcanized body 5; wherein, the "T" shaped rubber metal vulcanized body 5 is installed in the middle of the I-shaped rubber metal vulcanized body 4, so that the rubber metal vulcanized body of the whole ball dumpling is divided into three parts in the axial direction; the "T" shaped rubber metal vulcanized body After the metal vulcanized body 5 is combined with the I-shaped rubber metal vulcanized body 4, they are simultaneousl...

Embodiment 2

[0041] 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 adjusting the axial stiffness, further adjustments are made to the multi-lobe multi-layer rubber-metal laminated spring. A ball hinge with a ball hinge variable stiffness method in which an I-shaped bush and a laminated spring are matched, including a shell sleeve, and a rubber metal vulcanized body is pressed into the shell sleeve, and the ball joint is realized through the deformation of the rubber metal vulcanized body The nonlinear variable stiffness; the rubber metal vulcanized body is divided into two parts, one is an I-shaped rubber metal vulcanized body, and the other is a "T" shaped rubber metal vulcanized body; wherein, the "T" shaped rubber metal vulcanized body is installed on In the middle of the I-shaped rubber metal vulcanized body, the rubber metal vulcanized body of the whole ball dumpling is divided int...

Abstract

The invention discloses a spherical hinge axial variable stiffness method for matching an I-shaped bushing with a laminated spring. According to the method, the nonlinear variable stiffness of a rubber metal composite spherical hinge is adjusted by adjusting the position relation between the metal part and the rubber part of the rubber metal composite spherical hinge, the nonlinear variable stiffness of the rubber metal composite spherical hinge adjusted by adjusting the position relation between the metal part and the rubber part of the rubber metal composite spherical hinge is characterizedin that the metal part and the rubber part of the spherical hing are divided into two parts, one part is the I-shaped lining, and the other part is the laminated spring, the axial variable stiffness of the rubber metal composite spherical hinge and the axial variable stiffness of the small stiffness are realized through the I-shaped bushing, meanwhile, the axial variable stiffness of the large stiffness of the rubber metal composite spherical hinge is realized through the laminated spring, the nonlinear variable stiffness adjustment of the whole spherical hinge is realized through the combination of the two parts, so that the stiffness of the whole rubber metal composite spherical hinge is changed in the radial direction and the axial direction.

Description

technical field [0001] The invention relates to a method and product for variable stiffness of rail vehicle components, in particular to a method for adjusting nonlinear variable stiffness of rubber-metal composite ball hinges and a ball hinge, the rubber-metal composite ball hinge nonlinear variable stiffness adjustment The method and the ball joint can realize the highly nonlinear radial and axial rigidity of the ball joint at the same time, thereby providing bogie design with the installation possibility of realizing longitudinal bearing by the axial direction of the ball joint, belonging 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 tracti...
