Abstract
The utility model discloses a kind of Combined cylinder body, including cylinder holes portion, the cylinder holes portion includes：Machine body cylinder hole portion, which is formed on the body of cylinder block；And cylinder cap cylinder holes portion, which is formed in cylinder head；When wherein cylinder head is arranged on body, machine body cylinder hole portion and cylinder cap cylinder holes portion are combined into cylinder holes portion.The Combined cylinder body, it is to avoid cylinder pad is washed out by combustion gas.
Description
Technical field
This utility model is related to field of internal combustion engine, more particularly to a kind of Combined cylinder body.
Background technology
Usually, conventional composite formula cylinder block cylinder holes is usually dynamic with dry cylinder liner coordinates or interference fits loading body,
Dry cylinder liner outer surface is not contacted with cooling water, therefore no-cooling-water sealing problem.It is close between part and cylinder head in cylinder jacket
Envelope forms band with cylinder pad is pressurized by dry liner.
In the prior art scheme, dry cylinder liner convex shoulder width is little, it is desirable to have bulge quantity just have good sealing, to cylinder
Pad has high demands, and convex shoulder is pressurized big, is easily broken off, and cylinder pad is easily washed out by combustion gas.Convex shoulder and body same plane, seal 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, cylinder sleeve is made
Deformation.
The information for being disclosed in the background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or implying in any form that the information structure is existing well known to persons skilled in the art
Technology.
Utility model content
The purpose of this utility model is 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, this utility model provides a kind of Combined cylinder body, including cylinder holes portion, and the cylinder holes portion wraps
Include：Machine body cylinder hole portion, which is formed on the body of cylinder block；And cylinder cap cylinder holes portion, which is formed in cylinder head；Wherein cylinder
When lid is 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 is with the locating slot coordinated with shoulder.
Preferably, the matching part in cylinder jacket and cylinder cap cylinder holes portion is interference fit, and cylinder jacket is matched somebody with somebody with machine body cylinder hole portion
Close position to coordinate for gap.
Preferably, damping trough is provided with the inside of machine body cylinder hole portion, the damping trough is used for installing rubber ring.
Compared with prior art, this utility model has the advantages that：Cooperatively formed by cylinder block and head
Body cylinder holes, is partly installed in cylinder jacket in cylinder head, is partly installed in cylinder block under cylinder jacket, without the need for cylinder pad,
Therefore not there are problems that rushing cylinder pad.And solve the problems, such as cylinder jacket processing, body casting and poor in processability.
Description of the drawings
Fig. 1 is the structural representation according to Combined cylinder body of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by specific embodiment.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or ingredient, and do not exclude other units
Part or other ingredients.
As shown in figure 1, according to a kind of Combined cylinder body of this utility model specific embodiment, including cylinder holes portion, should
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
Hole portion is formed in cylinder head 1, and 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 stagewise fit system shape
Into top is divided into cylinder head 1, and bottom is divided into cylinder block 2, and 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 the need for cylinder pad, therefore do not exist and rush cylinder pad
Problem.And, without water cavity around the cylinder holes of the body of the internal combustion engine, this simplifies body casting technique, strengthens the strong of body
Degree, reduces cylinder centre line spacing, reduces body weight.
Used as a kind of preferred embodiment, cylinder holes portion is used for installing cylinder jacket 3, sets on the outer wall of the middle part of cylinder jacket 3
There is the joining place of shoulder 31, machine body cylinder hole portion and cylinder cap cylinder holes portion with the locating slot coordinated with shoulder 31.In processing, cylinder
Lid 1 pushes up bottom distance by controlling the shoulder 31 of cylinder jacket 3 with the size of locating slot to adjust with cylinder jacket 3, when solving Cylinder sticking,
3 axial displacement problem of cylinder jacket and machining cylinder block manufacturability issues.
Used as a kind of preferred embodiment, the matching part in cylinder jacket 3 and cylinder cap cylinder holes portion is interference fit, cylinder jacket 3 with
The matching part of machine body cylinder hole portion coordinates for gap.Cooperation in this programme, on the shoulder of cylinder jacket 3 partly with cylinder cap cylinder holes portion
For interference fit, under the shoulder of cylinder jacket 3, part is coordinated for gap with machine body cylinder hole portion, can improve dissipating for cylinder head high-temperature region
Heat energy power.
As a kind of preferred embodiment, damping trough 21 on the inside of machine body cylinder hole portion, is provided with, the 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, to partly having side force, the damping under cylinder jacket
Groove 21 can effectively prevent 3 periodic alternate stress of cylinder jacket, prevent 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, is partly installed under cylinder jacket 3 in cylinder block 2, without the need for cylinder pad, therefore there is no punching
Cylinder pad problem.And solve the problems, such as cylinder jacket processing, body casting and poor in processability.
The aforementioned description to specific illustrative embodiment of the present utility model be in order to illustrate and illustration purpose.These
Description is not wishing to for this utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
