Abstract
The invention discloses a combined type cylinder block which comprises a cylinder hole part. The cylinder hole part comprises a machine body cylinder hole part formed on a machine body of the cylinder block, and a cylinder cover cylinder hole part formed on a cylinder cover; and when the cylinder cover is installed on the machine body, the machine body cylinder hole part and the cylinder cover cylinder hole part are combined to form the cylinder hole part. The combined type cylinder block prevents a cylinder mat from being damaged by impact of fuel gas.
Description
Technical field
The present invention relates to field of internal combustion engine, particularly to a kind of Combined cylinder body.
Background technology
Usually, conventional composite formula cylinder block cylinder holes and dry cylinder liner are usually dynamic cooperation or interference fits load body,
Dry cylinder liner outer surface is not contacted with cooling water, therefore no-cooling-water sealing problem.Close between part and cylinder head in cylinder jacket
Envelope forms band by dry liner with cylinder pad is pressurized.
In the prior art scheme, dry cylinder liner convex shoulder width little it is desirable to there be bulge quantity just can have good sealing, to cylinder
Pad has high demands, and convex shoulder is pressurized big, is easily broken off, cylinder pad is easily washed out by combustion gas.Convex shoulder and body same plane, sealing is fair,
But technological requirement is strict, and cylinder pad is easily washed out by combustion gas.During the Cylinder sticking of cylinder sleeve lower end, cylinder sleeve axial displacement may be caused, make cylinder sleeve
Deformation.
The information being disclosed in this background section is merely intended to increase the understanding of the general background to the present invention, and should not
Recognize when being considered or imply in any form that this information structure has been the prior art well known to persons skilled in the art.
Content of the invention
It is an object of the invention to provide a kind of Combined cylinder body, it is to avoid cylinder pad is washed out by combustion gas.
For achieving the above object, the invention provides a kind of Combined cylinder body, including cylinder holes portion, this cylinder holes portion includes：
Machine body cylinder hole portion, it is formed on the body of cylinder block；And cylinder cap cylinder holes portion, it is formed in cylinder head；Wherein cylinder head
When being arranged on body, machine body cylinder hole portion and cylinder cap cylinder holes portion are combined into cylinder holes portion.
Preferably, cylinder holes portion is used for installing cylinder jacket, and the outer wall of the middle part of cylinder jacket is provided with shoulder；Body cylinder holes
The joining place in portion and cylinder cap cylinder holes portion has the locating slot with shoulder cooperation.
Preferably, cylinder jacket and the matching part in cylinder cap cylinder holes portion are interference fit, and cylinder jacket is joined with machine body cylinder hole portion
Close position to coordinate for gap.
Preferably, the inner side of machine body cylinder hole portion is provided with damping trough, and this damping trough is used for installing rubber ring.
Compared with prior art, the present invention has the advantages that：Body is cooperatively formed by cylinder block and head
Cylinder holes, cylinder jacket is partly installed in cylinder head, is partly installed in cylinder block under cylinder jacket, without cylinder pad, therefore not
Exist and rush cylinder pad problem.And solve the problems, such as cylinder jacket processing, body casting and poor in processability.
Brief description
Fig. 1 is the structural representation of the Combined cylinder body according to the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by specific embodiment.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " inclusion " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other part.
As shown in figure 1, according to a kind of Combined cylinder body of the specific embodiment of the invention, including cylinder holes portion, this cylinder holes
Portion includes machine body cylinder hole portion and cylinder cap cylinder holes portion, and wherein machine body cylinder hole portion is formed on the body of cylinder block 2, cylinder cap cylinder holes portion
It is formed in cylinder head 1, when cylinder head 1 is arranged on body, machine body cylinder hole portion and cylinder cap cylinder holes portion are combined into cylinder holes portion.
In such scheme, the cylinder holes of Combined cylinder body includes cylinder block and head two parts segmented fit system shape
Become, top is divided into cylinder head 1, bottom is divided into cylinder block 2, the cylinder holes of Combined cylinder body is used for installing cylinder jacket 3, cylinder jacket 3
On be partly installed in cylinder head 1, be partly installed under cylinder jacket 3 in cylinder block 2, without cylinder pad, therefore do not exist and rush cylinder pad
Problem.And, no water cavity around the cylinder holes of the body of this internal combustion engine, this makes body casting technique simplify, and strengthens the strong of body
Degree, reduces cylinder centre line spacing, reduces body weight.
As a kind of preferred embodiment, cylinder holes portion is used for installing cylinder jacket 3, and the outer wall of the middle part of cylinder jacket 3 sets
There is shoulder 31, the joining place in machine body cylinder hole portion and cylinder cap cylinder holes portion has the locating slot with shoulder 31 cooperation.In processing, cylinder
Lid 1 is adjusted with the size of locating slot by controlling the shoulder 31 of cylinder jacket 3 with the top bottom distance of cylinder jacket 3, when solving Cylinder sticking,
Cylinder jacket 3 axial displacement problem and machining cylinder block manufacturability issues.
As a kind of preferred embodiment, cylinder jacket 3 is interference fit with the matching part in cylinder cap cylinder holes portion, cylinder jacket 3 with
The matching part of machine body cylinder hole portion coordinates for gap.In this programme, the partly cooperation with cylinder cap cylinder holes portion on the shoulder of cylinder jacket 3
For interference fit, under the shoulder of cylinder jacket 3, part and machine body cylinder hole portion coordinate for gap, can improve dissipating of cylinder head high-temperature region
Heat energy power.
As a kind of preferred embodiment, the inner side of machine body cylinder hole portion is provided with damping trough 21, and this damping trough 21 is used for installing rubber
Cushion rubber.In this programme, in this programme, due to coordinating for gap between cylinder block 2 and cylinder jacket 3, therefore it is located at lower end and is provided with
Damping trough 21, is equipped with O-shaped rubber ring in damping trough 21.When descent of piston, partly there is side force under cylinder jacket, this damping
Groove 21 can effectively prevent the periodic alternate stress of cylinder jacket 3, prevents the fatigue rupture of cylinder jacket 3.
To sum up, the Combined cylinder body of the present embodiment, cooperatively forms body cylinder holes, cylinder by cylinder block 2 and cylinder head 1
It is partly installed in cylinder head 1 on set 3, be partly installed under cylinder jacket 3 in cylinder block 2, without cylinder pad, therefore there is not punching
Cylinder pad problem.And solve the problems, such as cylinder jacket processing, body casting and poor in processability.
The description of the aforementioned specific illustrative embodiment to the present invention illustrate that and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can much be changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that the certain principles of the present invention and its reality should
With so that those skilled in the art be capable of and utilize the present invention various different exemplary and
Various different selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
