Technical field
This utility model is related to field of internal combustion engine, more particularly to a kind of body of internal combustion engine.
Background technology
Usually, the body cylinder holes of traditional combustion engine is usually dynamic with cylinder sleeve coordinates or interference fits loading body, cylinder sleeve
Outer surface is not contacted with cooling water, therefore no-cooling-water sealing problem.Sealing in cylinder jacket between part and cylinder head is by cylinder
Set and the pressurized formation band of cylinder pad.
In the prior art scheme, shoulder of cylinder liner width is little, it is desirable to have bulge quantity just have good sealing, will to cylinder pad
Ask high, 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, seal fair, but work
Skill requires that strictly 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-liner distortion is made.
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 body of internal combustion engine, it is to avoid cylinder pad is washed out by combustion gas.
For achieving the above object, this utility model provides a kind of body of internal combustion engine, including:Cylinder block, the cylinder block
It is upper that there is machine body cylinder hole portion;Cylinder head, has cylinder cap cylinder holes portion in the cylinder head, cylinder head is fixedly mounted in cylinder block, machine
Body cylinder holes portion and cylinder cap cylinder holes portion combine the joining place in the cylinder holes of the body to form internal combustion engine, machine body cylinder hole portion and cylinder cap cylinder holes portion
With locating slot;And cylinder jacket, which is used in cylinder holes, and the outer wall of the middle part of cylinder jacket is provided with shoulder, platform
Shoulder is coordinated with locating slot.
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.
Preferably, the number of damping trough is two.
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, cylinder jacket
Support convex shoulder (shoulder), without the need for cylinder pad therefore not there are problems that rushing cylinder pad positioned at the centre position of cylinder jacket.And solve cylinder jacket
The problem of processing, body casting and processing technology difference.
Description of the drawings
Fig. 1 is the structural representation of the body according to internal combustion engine 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, a kind of body of the internal combustion engine according to this utility model specific embodiment, including cylinder block 2, gas
Cylinder cap 1 and cylinder jacket 3, have machine body cylinder hole portion in the cylinder block 2, have cylinder cap cylinder holes portion, cylinder head 1 in the cylinder head 1
It is fixedly mounted in cylinder block 2, machine body cylinder hole portion and cylinder cap cylinder holes portion combine the cylinder holes of the body to form internal combustion engine, body cylinder holes
The joining place in portion and cylinder cap cylinder holes portion has locating slot (position coordinated with shoulder 31), and cylinder jacket 3 is used in cylinder holes,
The outer wall of the middle part of cylinder jacket 3 is provided with shoulder 31, and shoulder 31 is coordinated with locating slot.
In such scheme, the body of internal combustion engine is formed by cylinder block and head stagewise fit system, and top is divided into
Cylinder head 1, bottom are divided into cylinder block 2, and middle is cylinder jacket 3, and cylinder head 1 is partly installed in cylinder jacket 3, cylinder jacket 3
Under be partly installed in cylinder block 2, the support convex shoulder (shoulder 31) of cylinder jacket 3 positioned at the centre position of cylinder jacket 3, without the need for cylinder
Pad, therefore not there are problems that rushing cylinder pad.In processing, cylinder head 1 passes through to control the platform of cylinder jacket 3 with the top bottom distance of cylinder jacket 3
The size of shoulder 31 and locating slot adjusting, when solving Cylinder sticking, 3 axial displacement problem of cylinder jacket and machining cylinder block manufacturability issues.
And, without water cavity around the cylinder holes of the body of the internal combustion engine, this simplifies body casting technique, strengthens the intensity of body, subtracts
Little cylinder centre line spacing, reduces body weight.
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 2 with
The matching part of machine body cylinder hole portion coordinates for gap.In this programme, on the shoulder of cylinder jacket 3, part is matched somebody with somebody with cylinder cap cylinder holes portion
Interference fit is combined into, part is coordinated for gap with machine body cylinder hole portion under the shoulder of cylinder jacket 3, can improve cylinder head high-temperature region
Heat-sinking capability.
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, 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, subtract
O-shaped rubber ring is equipped with shake groove 21.When descent of piston, to partly there is side force under cylinder jacket, the damping trough 21 can have
What is imitated prevents 3 periodic alternate stress of cylinder jacket, prevents the fatigue rupture of cylinder jacket 3.
Used as a kind of preferred embodiment, the number of damping trough 21 is two.
To sum up, the body of the internal combustion engine 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, the support convex shoulder of cylinder jacket 3
(shoulder 31), without the need for cylinder pad therefore not there are problems that rushing cylinder pad positioned at the centre position of cylinder jacket 3.And solve cylinder jacket and add
The problem of work, 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
