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

Provided is a traction spherical hinge non-linear variable rigidity method and an I-shaped bush. The non-linear variable rigidity of a spherical hinge is achieved through a rubber metal vulcanizationbody in the spherical hinge. The rubber metal vulcanization body is a rubber metal composite part of the I-shaped bush, an inner sleeve of the rubber metal composite part is in an I shape, and a coreshaft is sleeved with the inner sleeve. Radial rubber metal vulcanization composites formed through vulcanization rubber and metal are arranged at the two ends of the I-shaped inner sleeve correspondingly. An outer sleeve of the I-shaped rubber metal vulcanization body is divided into two sections, and the two ends are located at the two ends of the I-shaped rubber metal vulcanization body correspondingly and vulcanized with rubber to form an outer sleeve of the radial rubber metal vulcanization composites. The two sections of the outer sleeve are pressed at the two axial ends in a shell sleeve through interference fit, a two-section radial rubber metal composite spherical hinge is formed, and a sealed space is reserved in the middle of the two-section radial rubber metal composite spherical hinge. Non-linear variable rigidity adjustment of the spherical hinge is achieved through the two-section radial rubber metal composite spherical hinge.

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 varying stiffness in the axial direction of a rail vehicle traction ball hinge and a spherical hinge component. The stiffness method and the ball joint parts can realize the non-linear adjustment of the axial stiffness height of the ball joint at the same time, thus providing bogie design with the installation possibility of realizing the longitudinal bearing by the ball joint axial direction, and 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 ca...
