Embodiment
To help those skilled in the art definitely to understand claimed theme, below in conjunction with the accompanying drawings
Detailed description of the present invention embodiment.
Referring to Fig. 1, the air cylinder structure of engine includes cylinder block 2, cylinder head 3 and positioned at the cylinder between both
Gasket 1, cylinder head 3 are equipped with bolt 31, which fixes through cylinder gasket 1 and with cylinder block 2.It is equipped with cylinder block 2
Multiple cylinders, each cylinder embed cylinder sleeve（It is not shown）.Cylinder gasket 1 is equipped with multiple holes corresponding to cylinder, and is covered in
In cylinder port, this some holes alignment cylinder port.The combustion chamber 21 of cylinder port has been obtained sealing due to the addition of cylinder gasket 1 and protected
Barrier.Cylinder gasket 1 can coordinate cast aluminium engine cylinder body to use.
Each working cycles of engine are, it is necessary to undergo the Four processes such as air inlet/compression/combustion/exhaust, in the burning of cylinder mouth
This narrow region of room 21, forms a macroscopical relative motion.Fuel gas temperature reaches as high as 2000 in cylinder
DEG C, explosion pressure reaches as high as 120bar, and in order to reliably seal, cylinder gasket 1 has used full convex ribs to carry out sealed combustion chamber 21, i.e.,
A circle is equipped with around the convex ribs of cylinder port to provide enough sealings along hole on cylinder gasket 1.Cylinder block 2 and cylinder head 3 exist
The displacement of different trips is produced under each cycle of engine, due to the elastic reaction of cylinder gasket 1, convex ribs produce during this
Deformation energy good sealing force is provided.
Fatigue cracking of the convex ribs in the case of long-time compression rebound is, it is necessary to spacing knot using laser welding in order to prevent
Structure limits the stroke of convex ribs, prevents the convex ribs from forming excessive compression rebound.As shown in Fig. 2, a position limiting structure 14 passes through laser
Welding is connected with cylinder gasket 1, is arranged along cylinder mouth combustion chamber periphery, in the position view shown in the figure, position limiting structure
14 position is just in the top of cylinder sleeve 22.
Cylinder sleeve 22 is iron material, is to be combined together by casting and aluminium, position is below cylinder deck at 2.5mm.Just
Because the position limiting structure 14 of the laser welding exists, equivalent to being applied with a very big power on cylinder sleeve 22, while in high temperature
Lower aluminum mechanical performance declines, and along with the thermal coefficient of expansion of iron and aluminium is inconsistent, aluminium produces plastic deformation, that is, sinks, lead
The compression and rebound stroke for causing convex ribs 13 also become larger, and can not recur in some critical point to sealing function, and produce gas leakage.
The either fatigue cracking under multiple great compression rebound stroke of convex ribs 13, produces gas leakage.Cylinder mouth gas leakage
High-temperature gas will be caused to be directly entered coolant so that engine temperature improves rapidly, and combustion chamber periphery produces ablation phenomen, hair
Motivation can not remain in operation, and result even in engine fires under limiting case and cause security incident.
In view of the sinking of 22 position of cylinder sleeve, main cause comes from the power of the top of cylinder sleeve 22 and the common work of high temperature
With in order to improve this sinking, patent of the present invention proposes a kind of design concept for reducing by 22 top power of cylinder sleeve.In convex ribs 13
Bearing structure 15 is provided with opposite side relative to position limiting structure 14, which can shift position limiting structure 14 and apply
Active force on cylinder sleeve 22.
Referring to Fig. 3-4, Fig. 3 is a kind of structure diagram of embodiment of cylinder gasket of the present invention, and Fig. 4 is along figure
The section plan of line A-A in 3.Cylinder gasket 1 may include one layer of substrate 11 to multilayer, can be gold in the present embodiment
Belong to substrate.Corresponding to cylinder block 2, three separated holes 12 are provided with the substrate 11 of the cylinder gasket 1（I.e. cylinder block has three
Cylinder）, convex ribs are based on substrate 11 around cylinder port（See Fig. 4）, convex ribs can be completely about cylinder port, therefore is complete convex
Muscle 131, and adjacent full convex ribs 131 are tangent.In the inner side of convex ribs 131（That is inner ring）Equipped with position limiting structure, this is spacing
Structure is the spacing ring 141 of three whole circles, which can prevent the transition deformation of full convex ribs 131.Fig. 3 is returned to, complete
The outside of convex ribs, i.e., be equipped with bearing structure along the outer contour of full convex ribs, which closes to surround one of full convex ribs
The structure of shape, its concrete shape can be found in Fig. 5, and bearing structure 15 includes two incomplete annulars and two circular arcs, such as Fig. 5
Understand finding, annular two endpoint on the left side connects two sections of circular arcs respectively and two annular endpoints on the right connect.
Referring back to Fig. 6-7, be cylinder gasket of the present invention different embodiments profile shown in structure.It is complete convex
The side of muscle 131 is position limiting structure 14, and opposite side is bearing structure 15.Bearing structure 15 has certain height h and along hole 12
Width w in the radial direction.Height h and width w can coordinate the height of position limiting structure 14 to be adjusted.Because there are power
Distribution, the height h of bearing structure 15 are used for adjusting the ratio of power, but in the design process there is still a need for considering basic sealing
Demand, that is, set bearing structure 15 must be premised on meeting sealing demand.
In structure as shown in Figure 6, bearing structure 15 is discontinuous, i.e., by the bar shaped of multiple band height h and width w
Structural arrangement is formed.Certainly, bearing structure 15 can also be illustrated in figure 5 continuous structure.
Cylinder gasket 1 can have two-layer substrate, be respectively upper substrate 111 and infrabasal plate 112.On upper substrate 111 and
It is opposed to set convex ribs 13 on infrabasal plate 112, position limiting structure 14 and bearing structure 15 can be with being located on one piece of substrate, such as Fig. 6 institutes
Show, or one in position limiting structure 14 and bearing structure 15 is located on upper substrate 111, and another is located on infrabasal plate 112,
As shown in fig. 7, these structures can meet 1 Seal Design of cylinder gasket of the present invention.
Bearing structure 15 can be accomplished in several ways, such as directly go out as shown in Figure 6 to have one with mould punching
Determine the strip structure of height h and width w, or directly pass through laser welding or the form of riveting with the metal ring for cutting size
Be connected with substrate 11 etc..
For the engine structure shown in the application, position limiting structure is arranged on the inner ring of convex ribs, and above cylinder sleeve, pressure-bearing
The power of inner ring can be distributed to outer ring by the addition of structure, to reduce the deflection of cylinder port cylinder sleeve, therefore can use a variety of abilities
The conceivable achievable mode of field technique personnel and multiple material carry out the scattered of power.
Although being illustrated in detail in and the specific embodiment that the invention has been described being to illustrate the principle of the present invention, it should be understood that
, the present invention can be with embodied in other without departing from such principle.
