Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
As Figure 1-Figure 4, the embodiment of the invention discloses a kind of vibration absorber of rail vehicle assembly, the assembly to include rubber
Spherical hinge structure, shock absorber 4 and annular hanger 3, wherein, the quantity of annular hanger 3 is two, is respectively welded at the two of shock absorber 4
End, and rubber bushing structure is pressed into annular hanger 3 by external pressure.Rubber bushing structure includes mandrel 1 and ball pivot rubber
2, ball pivot rubber 2 is fixed on mandrel 1 by bonding by Vulcanization, the ball pivot of the middle part of the outer wall of ball pivot rubber 2 to the ball pivot rubber 2
The concave shape of rubber central shaft 21 circlewise sphere or ring-type V-arrangement face.In the present embodiment, mandrel 1 is multi-diameter shaft, in its external diameter most
Big medium position is socketed with ball pivot rubber 2.By the way that mating spherical surfaces are arranged between ball pivot rubber 2 and annular hanger 3, mandrel
1 is arranged to the measures such as multidiameter structure, reduces the manufacture difficulty and processing cost of mandrel 1, and mandrel 1 and ball pivot rubber 2 are logical
Cross molding vulcanization to form, it is easier to form ring-type V-arrangement face.
In the present embodiment, the inwall of the outer wall of ball pivot rubber 2 and annular hanger 3 is fitted close for ring-type V-arrangement face, annular
The inwall of hanger 3 convexes to form two monosymmetric inner conical faces 32 to the annular hanger central shaft 31 of the annular hanger 3, should
Inner conical face 32 is fitted close with male-tapered face 22, and its assembling is more prone to, and is more difficult to that deviation and play occurs during use, together
When, the thickness of the both sides of ball pivot rubber 2 can be bigger, and bearing capacity is more preferable, so as to increase the service life.
In the present embodiment, the outer wall of ball pivot rubber 2 forms two to the depression of ball pivot rubber central shaft 21 of the ball pivot rubber 2

Inner conical face 32 cone angle beta1For 10 ° -13 °.The service life of ball pivot rubber 2 and annular hanger 3 in above-mentioned angular range
It is longer, meanwhile, it is not in have end face to show especially and another that rubber bushing 2, which is pressed into exposed both sides rubber end face after annular hanger 3,
The recessed phenomenon of end face, by the taper surface matching design between ball pivot rubber 2 and annular hanger 3, make ball pivot rubber and ring
Being more uniformly stressed between shape hanger, the deviation for being further able to be better protected between ball pivot rubber 2 and annular hanger 3 are altered
It is dynamic, so as to which shock absorber 4 will not shift or play and then the problems such as cause oil leak so that the effect of vibration damping and noise reduction reaches most
Good state, and rubber bushing structure and the service life of vibration damper complement can be extended.
In the present embodiment, two end faces 23 of ball pivot rubber 2 are inclined-plane, and the outer wall of ball pivot rubber 2 is axially wide
Axial width of the degree less than inwall.Under the actual condition that annular hanger 3 is extruded ball pivot rubber 2, the both ends of the ball pivot rubber 2
Face 23 can improve the mechanical property of end face, it is more difficult to because of compression failure after being squeezed gradually to vertical direction deflection.
In the present embodiment, two end faces 23 of ball pivot rubber 2 and the angle beta of the vertical plane of the axis of vertical spindle 13It is preferred that
For 25 ° -35 °.
In order to ensure the installation accuracy between shock absorber 4 and rubber bushing structure, in the present embodiment, annular hanger 3 with
Locating slot 33 is provided with the relative face of shock absorber 4, positioning convex 41 is provided with corresponding shock absorber 4, wherein, positioning convex
41 are fastened in locating slot 33, can prevent shock absorber 4 with the annular welding process of hanger 3 because deformation dislocation etc. causes pair
Middle deviation and the problem of bring.
The preferred embodiments of the present invention are these are only, are not intended to limit the invention, for those skilled in the art
For member, the present invention can have various modifications and variations.Any modification within the spirit and principles of the invention, being made,
Equivalent substitution, improvement etc., should be included in the scope of the protection.
