Abstract

The invention relates to a shock absorbing method and structure of a spherical hinge for a wheelless axle bogie, which adopt the method of arranging a split composite layer structure between a metal inner sleeve and a metal outer sleeve to meet the performance requirements of the spherical hinge, wherein the composite layer structure is that a metal separator plate is arranged inside a rubber layer and is vulcanized to form a rubber-metal-rubber structure, and a parting surface is arranged at the splitting position of the composite layer structure to meet the radial, axial, deflection and torsional stiffness requirements, and reduce rubber stress. As the split composite lay structure is arranged between the metal inner sleeve and the metal outer sleeve, the invention can realize large radial pre-compression to rubber, improve radial rigidity of the spherical hinge and realize minimal torsional rigidity. The invention has the characteristics that the free surface of rubber is greatly increased by the parting surface arranged at the splitting position, which can greatly reduce the stress caused by the extrusion to rubber, improve the fatigue life of rubber and the service life of thespherical hinge.

Description

technical field

[0001] The invention relates to a damping method and structure of a ball joint, in particular to a damping method and structure of a ball joint for a wheel-axle bogie, and belongs to the technical field of rail transportation. Background technique

[0002] The axleless bogie is a completely different technology from traditional bogies such as BT, AT and domestic models. The speed of the vehicle covers 160 km-350 km per hour. The biggest feature of this axleless bogie is: the same bogie The two wheels can pass through the track curve at a differential speed, reducing wheel rim wear, and the vehicle is more stable when passing the curve, but at the same time, the various load conditions of the metal rubber parts are more severe. It has high technical requirements for various spherical joints, and products of the same structure need to be used in different positions. Therefore, the requirements for the bearing capacity of the product in all directions are high, ...
