The circumferencial direction of outer tube inner wall is equally spaced.
As the preferred of the outer barrel, the outer barrel is welded by thin-wall steel tube.
As the preferred of the inner cylinder, the inner cylinder is rubber tube.
In order to solve the above technical problems, the technical scheme that another embodiment of the present invention provides is：
A kind of automobile, including the capsule-type machine oil pulse buffer in preceding solution, the buffer installation
In its machine oil pipeline.
The capsule-type machine oil pulse buffer of the above-mentioned technical proposal of the present invention uses inside and outside double tube design, and outer barrel is firm
Property material, inner cylinder is elastic material, has larger gap between inside and outside cylinder；The machine oil chamber that machine oil enters in inner cylinder from import, then from
Outlet outflow；The beneficial effect of above-mentioned technical proposal is：
1. can effectively reduce the pulse effects that machine oil is formed in in-car pipeline using the buffer, and then eliminate thus
And the car body NVH problems come；
2. the damper volume is compact, installation is simple, it is not necessary to rearranges in-car pipeline trend for it；
3. the buffer main body can use steel construction, reliability is high, is hardly damaged, and has certain quality, can rise
To the effect for reducing oil pipe amplitude.

Embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
The present invention makes car body produce additional vibratory for the machine oil pulse shock in existing automobile pipeline influences car body NVH
The problem of energy, there is provided a kind of capsule-type machine oil pulse buffer, pulse shock of the machine oil to pipeline can be effectively reduced.
As shown in Figure 1 to Figure 3, a kind of capsule-type machine oil pulse buffer that the present embodiment provides, including rigid outer barrel 1
With the inner cylinder 3 of elastomeric material, inner cylinder 3 is arranged in outer barrel 1 and is fixedly connected with outer barrel 1；Cavity in inner cylinder 3 is for machine oil
The machine oil chamber 4 of circulation, the both ends of outer barrel 1 are respectively arranged with the machine oil import 5 connected with machine oil chamber 4 and machine oil outlet 6；The outer barrel
Closed cavity is formed between 1 inwall and the outer wall of inner cylinder 3, machine oil is only capable of flowing into machine oil chamber 4 by machine oil import 5, may not flow into
In the closed cavity；Be provided with supporting construction between outer barrel 1 and inner cylinder 3, supporting construction support under, the outer wall of inner cylinder 3 with
Larger gap is maintained between the inwall of outer barrel 1, space is provided for buffering engine oil pressure；
Conventional rigid metallic material is may be selected in the material of outer barrel 1, and for ease of processing, thin-wall steel tube is used in the present embodiment
The outer barrel 1 of tubular is made in welding, and thin-wall steel tube is the steel pipe in the field of business for refering in particular to the ratio between outer diameter of steel pipes and wall thickness and being more than 20；Using steel
The outer barrel 1 of matter, device is integrally hardly damaged, and reliability improves, and the device with certain quality is installed in oil circuit, can be risen
To the further effect for suppressing tubing vibration, reduce amplitude；
Inner cylinder 3 is made using elastomer, can be deformed upon and can be resetted rapidly under machine oil pulse；Specifically, this implementation
Inner cylinder 3 is with larger elastic rubber tube in example, naturally it is also possible to selects other elastomeric materials suitable for machine oil operating mode；
As supporting construction preferred embodiment, such as Fig. 2 and Fig. 3, supporting construction is on the inwall of outer barrel 1 in the present embodiment
Some projections 2 towards inner side, projection 2 quantity select six, axially distributed is two groups, every group of three edges of projection 2
The circumferencial direction of the inwall of outer barrel 1 is equally spaced；Supporting construction can also select other than raised 2 more complicated structures, such as spring
Piece etc.；Meanwhile quantity also can be selected suitably as needed with arrangement mode, as long as the support positioning action to inner cylinder 3 can be realized
.
During using the buffer, the buffer is connected in the machine oil pipeline of automobile, machine oil enters along pipeline from machine oil
Mouth 5 enters in the machine oil chambers 4 that buffer inner cylinder 3 is formed, and is flowed out after flowing through inner cylinder 3 from machine oil outlet 6；In order to increase machine oil chamber 4
Deformation buffer space, in six projections 2 to inner side that the inwall of outer barrel 1 of metal thin-wall is set, outer barrel 1 and inner cylinder 3 it
Between overhang larger gap, when machine oil pulse arrives, rubber thin-walled form inner cylinder 3 under pulsed force function, can produce very
Big elastic deformation, intracavitary volume become big, can accommodate the unnecessary machine oil that machine oil pulse is brought, and that offsets that unnecessary machine oil brings rushes
Hit.So as to play a part of slowing down or eliminate machine oil pulse.
In order to which above-mentioned technical proposal is better achieved, present invention also offers a kind of automobile, including in preceding solution
Capsule-type machine oil pulse buffer, buffer be arranged on its machine oil pipeline in.
By installing the buffer additional in machine oil pipeline, the pulse effect that machine oil is formed in in-car pipeline can be effectively reduced
Should, and then eliminate resultant car body NVH problems；Need not be that it rearrange car and damper volume is compact, during installation
Interior pipeline trend.
