Embodiment 1

[0050] Such as Figure 1-Figure 3 As shown, a structure that changes the stiffness of the axle box positioning node by adjusting the parameters of the rubber layer, that is, the axle box positioning node, includes a mandrel 1, a rubber layer 2, a split casing 3, an overall casing 4, and a rubber layer 2 vulcanized bonding core On the outside of the shaft 1, the split casing 3 is set on the outside of the mandrel 1, and the integral casing 4 is set on the outside of the split casing 3, wherein the rubber layer 2 is a hollow I-shaped structure, and the outer sides of the two ends of the I-shape are in line with the The inner concave surface in the middle is connected with slope one 21, and the outer surface at both ends of the I-shape is connected with the hollow inner surface with slope two 22. The rubber layer 2 is designed as a hollow I-shaped structure. When adjusting the axial and longitudinal stiffness, it can be realized by changing the different values ​​of multiple part...

Embodiment 2

[0065] This embodiment is basically the same as Embodiment 1, the difference is: as Figure 5 As shown, in the rubber layer 2, the extension lines of the busbars corresponding to the first slope 21 and the second slope 22 intersect with each other. , One end of the curved surface 23 is connected with the inclined surface 22, and the other end is connected with the inclined surface 21. Specifically, the angle A1 between the slope-21 of the rubber layer 2 and the inner concave surface is 78 o .

Embodiment 3

[0067] This embodiment is basically the same as the above-mentioned embodiment, the difference is: as Figure 6 As shown, one end of the first curved surface 23 of the rubber layer 2 is connected to the second inclined surface 22, and the other end is connected to the outer surface. Specifically, the length L1 of the concave surface between the two slopes one 21 on the outside of the rubber layer 2 is 61.5 mm, the thickness D1 of the rubber on the concave surface of the rubber layer 2 is 19 mm, and the thickness D2 between the slope one 21 and the two slopes 22 of the rubber layer 2 is is 27mm.

[0068] This shows that the present invention has the following beneficial effects:

[0069] 1. In the present invention, the positioning node of the axle box is set as a structure in which a rubber layer is provided on the outside of the mandrel, a split jacket is arranged outside the rubber layer, and a whole jacket is arranged outside the split jacket, and the axle box is adjusted ...

Abstract

The invention discloses a method for adjusting rigidity of an axial box positioning node by adjusting parameters of rubber layer and its structure. The method includes steps of arranging an axial boxpositioning node to outside of a mandrel to vulcanize and bond a rubber layer; arranging an outer sectioning sleeve at the outside of the rubber layer, and arranging a whole outer sleeve structure atthe outside of the outer sectioning sleeve, wherein the rubber layer is a hollow transverse-H structure, and both ends of the outside of the transverse-H structure are connected with an inner concaveface of the middle by a first oblique face, and two end faces are connected to a hollow inside face by a second oblique face; changing different rigidity value of the axial box positioning node in every direction through adjusting the value of every parameter of the rubber layer, so as to meet different rigidity demands of different models of vehicles on the axial box positioning node in every direction. According to the method and its structure, the rubber layer is designed to the hollow transverse-H structure; the axial and longitudinal rigidities are adjusted through changing different values of multiple parts of the rubber layer, the adjustable scales of axial and longitudinal rigidities are further enlarged.

Description

technical field [0001] The invention relates to a method for changing the stiffness of an axle box positioning node and the axle box positioning node, in particular to a method and structure for changing the stiffness of an axle box positioning node by adjusting rubber layer parameters, and belongs to the technical field of rail vehicle component manufacturing. Background technique [0002] The axle box structure is the movable joint connecting the frame and the wheel set on the rail vehicle. In addition to transmitting forces and vibrations in various directions, the axle box structure must also ensure that the wheel set can jump up and down and move side to side relative to the frame to adapt to the track conditions. Axle box positioning is also wheel set positioning, that is, restricting the mutual position between the wheel set axle box and the frame. The load is transmitted and distributed to the wheelset; the wheelset rotates flexibly, and the bogie passes the curve sm...
