Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in detail.It should be appreciated that
Detailed description of the invention described herein is merely to illustrate and explains the present invention, is not limited to this
Bright.
The present invention provides a kind of axle sleeve vibroshock, including rubber axis body 10, caulking gum block 20 and gold
Belonging to shell 30, rubber axis body 10 has the axis hole 11 passed for outer connecting shaft (not shown), rubber
Being provided with the first groove 12 on the outer peripheral face of sleeve body 10, caulking gum block 20 is embedded at the first groove
Separate to form the oil pocket closed in 12 and with the bottom of this first groove 12, this oil pocket is filled with resistance
Buddhist nun's liquid 60, is additionally provided with air chamber 80 in described oil pocket, the cavity of air chamber 80 is fabricated from a flexible material,
Inside is filled with air, and metal shell 30 is wrapped on rubber axis body 10 and caulking gum block 20.
Here, refer to can be with the material of crimp for term " flexible material ".
By technique scheme, when the outer connecting shaft generation medium and low frequency vibration being arranged in axis hole 11,
When external applied load that axle sleeve vibroshock bears is bigger, caulking gum block 20 under the effect of external applied load towards
The bottom of one groove 12 is moved so that the volume of oil pocket diminishes, and the pressure of damping fluid 60 becomes big, thus
Compressing air chamber 80 deforms so that the air pressurized in air chamber 80 produces heat energy, in this way
Convert vibrational energy into heat energy to dissipate, it is achieved that the function of low and medium frequency vibration damping under top load.
In order to make axle sleeve vibroshock all have preferable damping property on whole circumferencial direction, it is preferable that
As in figure 2 it is shown, be provided with multiple first groove 12 on rubber axis body 10, the plurality of first groove 12
Along the circumferentially-spaced layout of rubber axis body 10, each first groove 12 is provided with caulking gum block
20。
The axle sleeve vibroshock of the present invention can also include metal lining 40 and metallic framework 70, wherein, gold
Belonging to lining 40 to be embedded in axis hole 11, metallic framework 70 is firm to increase in being embedded in rubber axis body 10
Property.In order to the heat in air chamber 80 is conducted quickly, it is preferable that as it is shown in figure 1, close
Blocking 90 is made up of metal (such as, aluminum or copper), and contacts with the lateral surface of metal lining 40.
The cavity of air chamber 80 can be formed by the flexible material of various suitable types, such as rubber.Empty
Air cavity 80 can be another parts independent of rubber axis body 10 and caulking gum block 20, it is also possible to
It is integrally formed with rubber axis body 10 or caulking gum block 20.In the embodiment shown in Fig. 1, empty
Air cavity 80 is integrally formed with rubber axis body 10, i.e. air chamber 80 is formed on the first groove
On the surface of 12.
Air chamber 80 can be formed at the optional position of the first groove 12 and can have the most suitable
Shape.As a kind of embodiment, as it is shown in figure 1, air chamber 80 is formed at described first groove 12
Bottom and extend towards caulking gum block 20, the opening of air chamber 80 extends to the hole wall of axis hole 11
And closed by sealing-plug 90.In this case, the heat energy that the air pressurized in air chamber 80 produces can
To be transmitted in air by sealing-plug 90, it is to avoid axle sleeve vibroshock affects its performance because of overheated.
In order to prevent caulking gum block 20 top load effect bottom offset excessive and with miscellaneous part (such as,
Air chamber 80) produce and interfere, as it is shown in figure 1, can arrange spacing on the side of the first groove 12
Platform 13, with block caulking gum block 20, limits its maximum displacement.
But, in order to ensure caulking gum block 20 have under top load effect abundance mobile space with
In oil pocket, produce enough pressure, limiting platform 13 can be arranged on than air chamber 80 top more
On low position, say, that the distance of the bottom of limiting platform the 13 to the first groove 12 is less than air
The top in chamber 80 is to the distance of the bottom of the first groove 12.In this case, in order to avoid sealing rubber
Blob of viscose 20 produces with air chamber 80 interferes, as it is shown in figure 1, can caulking gum block 20 towards
Second groove 21 is set to dodge air chamber 80, i.e. when caulking gum block on the surface of air chamber 80
20 when moving to limiting platform 13, and the top of air chamber 80 is positioned in the second groove 21.
As the preferred embodiment of the present invention, the opening of the second groove 21 connects flexible net orifice plate
50, this flexible net orifice plate 50 is provided with the multiple mesh 51 allowing damping fluid 60 to pass.Flexible mesh
Plate 50 has High-frequency absorber function concurrently and assists low frequency vibration damping function.Specifically, occur when outer connecting shaft
When external applied load that low-frequency vibration, axle sleeve vibroshock bear is bigger, on the one hand, flexible net orifice plate 50 is moving
The damping fluid 60 of surrounding can be produced disturbance, on the other hand, when the top of air chamber 80 during Dong
When interfering with flexible net orifice plate 50, flexible net orifice plate 50 is deformed, and also can make the resistance of surrounding
Buddhist nun's liquid 60 produces disturbance, and flexible net orifice plate 50 disturbance damping fluid 60 causes turbulent to consume vibrational energy,
Achieve assistance low frequency vibration damping function;Outside outer connecting shaft generation dither, axle sleeve vibroshock bear
When load is less, the displacement of caulking gum block 20 is less or is not subjected to displacement, but now damping fluid
60 shakes that can produce little scope, on the one hand the vibration of damping fluid 60 makes damping fluid 60 and the first groove
The side of 12 produces friction, on the other hand makes damping fluid 60 produce friction with the hole wall of mesh 51, from
And convert vibrational energy into heat, it is achieved that the function of High-frequency absorber under low load.
Flexible net orifice plate 50 can be made up of various flexible materials, such as rubber.
Air chamber 80 can have various suitable structure.As a kind of embodiment, as it is shown in figure 1,
Air chamber 80 can include the sidewall 81 that roof 82 is relative with two, the lower limb of each sidewall 81 with
The bottom of the first groove 12 is connected, two lateral edges respectively with two relative sides of the first groove 12
It is connected.A pair lateral edges of roof 82 top edge with two sidewalls 81 respectively is connected, another opposite side
Relative with the said two of the first groove 12 respectively side of edge is connected, and the opening of air chamber 80 runs through the
The bottom of one groove 12 is also blocked by sealing-plug 90.Air chamber 80 moulding process of this kind of version
Relatively simple, robustness is higher.In this embodiment, in order to make air chamber 80 be more susceptible to buckling
Shape, as it is shown in figure 1, roof 82 can be formed as the curved surface of evagination, sidewall 81 can be formed as indent
Curved surface.
As another embodiment, air chamber 80 can include roof and annular sidewall, annular sidewall
Lower limb and the first groove 12 bottom be connected, top edge is connected with roof, the opening of air chamber 80
Run through the bottom of the first groove 12 and blocked by sealing-plug 90.
The axle sleeve vibroshock of the present invention is suitably applied in the various plant equipment needing vibration damping, is especially suitable for
It is applied to vehicle to improve the handling and comfortableness of car load.Accordingly, as another aspect of the present invention,
Also providing for a kind of vehicle, this vehicle has axle sleeve vibroshock as above.
