Fig. 2 is the schematic cross-sectional view two of embodiment one；
In figure: 1 first inner sleeve, 2 second inner sleeves, 21 bottom plates, 22 inner sleeve main bodys, 3 rubber bodies, 4 first housings, 42 outer right-angle sides, 5
Second housing, bevel edge, 7 outer bevel edges, 8 rubber grooves in 6.
Specific embodiment
The description of a step is done to the present invention below with reference to embodiment and attached drawing:
Embodiment one
Traction flexural pivot be rotary body, draw the section of flexural pivot as shown in Figure 1, traction flexural pivot include the first inner sleeve 1, the second inner sleeve 2,
Rubber bodies 3, the first housing 4 and the second housing 5.The section of first inner sleeve 1 is T font, the first inner sleeve 1 assembling of two T fonts
The section formed together is the " I " fonts in Fig. 1.And the both ends of the first inner sleeve 1 have carried out bending, and formation is fluted, and second
Inner sleeve 2 enables the first inner sleeve 1 that the second inner sleeve 2 is prevented to move in the axial direction in the groove of the first inner sleeve 1.
Second inner sleeve 2 includes bottom plate 21 and inner sleeve main body 22, and bottom plate 21 and the seamless connection of inner sleeve main body 22 are at an entirety.
Bottom plate 21 is circular tube shaped, and the section of inner sleeve main body 22 is triangle, and the top of inner sleeve main body 22 is arc-shaped.
Groove is equipped in second housing 5, the two sides at 4 top of the first housing are provided with notch, pass through the groove in the second housing 5
With the cooperation of the notch in the first housing 4, the first housing 4 is embedded in the second housing 5.The two sides of first housing, 4 bottom are equipped with
Outer bevel edge 7, rubber bodies 3 vulcanize between the second inner sleeve 2 and the first housing 4, and the two sides of rubber bodies 3 are designed with rubber groove 8.
The section for drawing flexural pivot is as illustrated in fig. 1 and 2, and the section as shown in the figure for traction flexural pivot, traction flexural pivot is rotary body.
Deflection direction refers to that the direction that the traction flexural pivot in figure rotates to the left or to the right, the direction of torsion are the circumference side for drawing flexural pivot
To.Axial direction refers to the transverse direction in figure, and the vertical direction in figure is radial direction.Without wheel axle bogie emu vehicle
When driving, need to make to draw that flexural pivot meets axial rigidity and torsion stiffness is big, and radial rigidity and the small performance of deflection stiffness are wanted
It asks.
In the present embodiment, the section of inner sleeve main body 22 is an isosceles triangle, and the apex angle of isosceles triangle is fallen
Angle, the half of the angle value of apex angle are angle A.The angle of the namely central axes of inner sleeve main body 22 and interior bevel edge 6 is angle A, axis
Line is the dotted line in Fig. 2.
When the value of angle A is bigger, in the case where the height of holding inner sleeve main body 22 is constant, the axial width of inner sleeve main body 22
Can be bigger, and the thickness of the rubber bodies 3 of 22 two sides of inner sleeve main body opposite can reduce, the rubber bodies 3 of 22 two sides of inner sleeve main body by
To axial direction active force when, deformation can reduce.That is, will increase axial rigidity.Same principle, reduce inner sleeve
The angle of 22 apex angle of main body can reduce the deflection stiffness of traction flexural pivot, and the angle for reducing 22 apex angle of inner sleeve main body can reduce tow ball
The radial rigidity of hinge, the angle for increasing 22 apex angle of inner sleeve main body can increase the torsion stiffness of traction flexural pivot.
The inside of first housing 4 is equipped with outer bevel edge 7, and the outside of the first housing 4 is equipped with outer right-angle side 42, adjusts outer bevel edge 7
Angle between outer right-angle side 42 is adjustable the radial rigidity of traction flexural pivot.The outer bevel edge 7 of first housing 4 and outer right-angle side 42
Between angle be angle B, the angle of angle B is bigger, draws the radial rigidity of flexural pivot with regard to smaller.This is because the angle of angle B is got over
Greatly, the thickness of the rubber bodies 3 between the interior bevel edge 6 of the inner sleeve main body 22 of the outer bevel edge 7 of the two sides of housing groove 41 and the second inner sleeve 2
It spends bigger.Therefore, the radial rigidity of traction flexural pivot can be reduced.
It is that rubber bodies 3 have been carried out with precompressed, the rubber bodies 3 after precommpression, by external force when flexural pivot is drawn in assembling
It is all less also easy to produce deformation in all directions afterwards, will increase the rigidity of large traction flexural pivot all directions.Therefore, increase precommpression
Deflection stiffness, axial rigidity, radial rigidity and the torsion stiffness of traction flexural pivot can be increased.
It will be apparent that without departing from the principles of the present invention, several improvement or modification made are regarded as this
The protection scope of invention.
