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 problem of present invention makes car body produce additional vibratory for the machine oil pulse shock in existing automobile pipeline, there is provided
A kind of machine oil pulse buffer, pulse shock of the machine oil to pipeline can be effectively reduced, eliminate the NVH problems thus brought.
As shown in Figure 1 to Figure 3, the present embodiment provide a kind of machine oil pulse buffer, including outer barrel 1, buffering diaphragm 4 and
Flexible restoring organ, wherein：
The buffering diaphragm 4 being arranged in outer barrel 1 is elastomer, can select have larger elastic rubber membrane, can also
Other elastomeric materials are selected as needed；Diaphragm 4 and the closely sealed connection of the inwall of outer barrel 1 are buffered, a sky is separated out in outer barrel 1
Chamber, two are provided with the cavity and is each passed through machine oil import 31 and machine oil outlet 32 that outer barrel 1 connects outside, the cavity is
Accommodating the machine oil chamber 2 of machine oil, when in buffer access machine oil pipeline, machine oil flows into machine oil chamber 2 from machine oil import 31, and from machine oil
The outflow of outlet 32；Diaphragm 4 is buffered using the side in machine oil chamber 2 as inner side, corresponding opposite side is outside；
Flexible restoring organ keeps contacting and synchronously deformed upon with buffering diaphragm 4 with buffering diaphragm 4；In specific implementation,
Flexible restoring organ can be arranged at outside machine oil chamber 2, be in contact with the outside of buffering diaphragm 4, with buffering diaphragm 4 under engine oil pressure
Deformation is compacted；It can also be arranged in machine oil chamber 2, be connected, buffering diaphragm 4 is pulled, with slow with the inner side of buffering diaphragm 4
Rush the deformation of diaphragm 4 elongation；As other embodiments, flexible restoring organ can also use a variety of in the prior art can be achieved
The device of elastic reset, such as the spring of diversified forms, push rod or pull bar that and for example elastomeric material makes etc. are in summary, elastic
As long as resetting-mechanism can aid in buffering the deformation of diaphragm 4 and realize the reset after deformation；In the present embodiment, such as Fig. 2 and
Shown in Fig. 3, flexible restoring organ includes spring 5 and spring fixed seat 6, and the one end of spring 5 is fixed on outer barrel by spring fixed seat 6
On 1, the other end is against the outside of buffering diaphragm 4, when buffering diaphragm 4 deforms upon outwards under the inner engine oil pulse of machine oil chamber 2
During expansion, spring 5 is compressed therewith, and when engine oil pressure reduces, under the auxiliary of the restoring force of spring 5, buffering diaphragm 4 is multiple
Position；
Outer barrel 1 is made up of sturdy material, and usually using metal material, the present embodiment is welded using thin-wall steel tube known in the industry
Connect and form, the thin-wall steel tube is the steel pipe of the ratio between outer diameter of steel pipes and wall thickness more than 20；Outer barrel is welded into using Steel Thin-Wall,
Make device firmer, improve overall reliability, be hardly damaged in the course of work；And have one using the device of steel construction
Fixed quality, it can play a part of suppressing tubing vibration, reduce the amplitude of vibration；
The working method of buffer is as follows in the present embodiment：Machine oil slave oil inlet 31 enters in machine oil chamber 2, impacts slow
Rush on diaphragm 4, then slave oil export 32 flows out；Because buffering diaphragm 4 is elastomer in itself, so being arrived in machine oil pulse
When, buffering diaphragm 4 can produce very big deformation, and now the volume of buffer inner engine oil chamber 2 becomes big, can accommodate machine oil pulse band
The unnecessary machine oil come, its impact brought is offset, the machine oil pulse that slave oil export 32 flows out can diminish, or disappear；Buffering
The spring 5 of the outside of diaphragm 4 arrangement, it can both help to buffer the carrying machine oil impulsive force of diaphragm 4, it is rapid to may also aid in buffering diaphragm 4
Reset.
