Abstract
The invention discloses a cylinder block. The cylinder block comprises a cylinder block body, a cylinder sleeve installation hole and a cam shaft installation hole; structures of a water jacket and a tappet hole are omitted from the cylinder block body; the cylinder sleeve installation hole is vertically formed at the middle portion of the cylinder block body, the axial length of the cylinder sleeve installation hole is smaller than or equal to the length of the lower half portion of a cylinder sleeve, and the center of the cylinder sleeve installation hole deviates from the center of a crankshaft; and the cam shaft installation hole is formed in the cylinder block body and is orthorhombic with the axial direction of the cylinder sleeve installation hole. According to the cylinder block, the structures of the water jacket and the tappet hole are omitted, so that the casting process of the cylinder block is simple, the weight is small, only the strength of an output part of an overall machine is borne, the height is small, the wall thickness of a skirt part is reduced, the weight of a machine body is further reduced, and the aim of light weight is achieved.
Description
Technical field
The present invention relates to engine art, particularly to a kind of cylinder block.
Background technology
With the raising to requirements such as power performance, economy, the feature of environmental protection for the socio-economic activity, vehicle and its parts
Lightweight become one acquisition extensive concern direction of improvement.
Existing diesel cylinder block has jacket structure for water and tappet pore structure, and not only complex structure, casting technique are complicated, and
And quality is overweight, the sealing for water route also has higher requirement, does not meet the light-weighted requirement of available engine.
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 simple and reasonable cylinder block, this cylinder block is endured by omitting water sleeve
Post holes structure is so as to casting technique is simple, and lightweight, only undertakes the output par, c intensity of whole machine, highly low, and reduces skirt
The wall thickness in portion, reduces body weight further, reaches light-weighted purpose.
For achieving the above object, the invention provides a kind of cylinder block, this cylinder block includes：Cylinder block body, its omission
Water sleeve tappet pore structure；Cylinder jacket installing hole, it is vertically opened in the middle part of described cylinder block body, this cylinder jacket installing hole
Axial length be less than or equal to cylinder jacket the latter half length, and in the center deviation bent axle of this cylinder jacket installing hole
The heart；And camshaft installing hole, it is opened on described cylinder block body, and orthogonal with the axial direction of described cylinder jacket installing hole.
Preferably, in technique scheme, the bottom of cylinder block body has skirt section, and this skirt section is laid with reinforcement.
Preferably, in technique scheme, center deviation crankshaft center 10mm of cylinder jacket installing hole.
Preferably, in technique scheme, between each cylinder jacket installing hole of cylinder block body, it is provided with fall repeated hole.
Preferably, in technique scheme, the top of cylinder block body has hydraulic fluid port, and this hydraulic fluid port seals shape by O-ring
Become the sealing structure of oil circuit.
Compared with prior art, the present invention has the advantages that：This cylinder block is passed through to omit water sleeve tappet hole knot
Structure is so as to casting technique is simple, and lightweight, only undertakes the output par, c intensity of whole machine, highly low, and reduces the wall in skirt section
Thickness, reduces body weight further, reaches light-weighted purpose.

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 Figures 1 to 4, the cylinder block according to the specific embodiment of the invention and compound cylinder cap respective outer side edges assembling.
The concrete structure of this cylinder block includes：Cylinder block body 1 and be opened in cylinder jacket installing hole 2 on this cylinder block body 1, convex
Wheel shaft installing hole 3.Wherein, cylinder block body 1 no jacket structure for water, tappet pore structure, height is very short so as to casting technique is simple,
And lightweight, only undertake the output par, c intensity of whole machine, and reduce the wall thickness in skirt section, reduce body weight further, reach
Light-weighted purpose.
Specifically, cylinder block body 1 is the main body of engine, is the basic structure of engine, is engine body group
Important component part, each cylinder and crankcase are connected between cylinder head and oil sump by it, are to install piston, song
Axle and the support framework of other parts and annex.Cylinder block body 1 no jacket structure for water, tappet pore structure are so as to casting technique
Simply.The top of cylinder block body 1 has hydraulic fluid port 7, and this hydraulic fluid port 7 seals the sealing structure forming oil circuit by O-ring.
The bottom of cylinder block body 1 has skirt section 5, for being connected with oil sump.The wall thickness in this skirt section 5 is very thin, reduces skirt
The wall thickness in portion, reduces body weight further, reaches light-weighted purpose.This skirt section 5 is laid with reinforcement 6, and this reinforcement 6 is high
Thin, equally can reduce body weight further, reach light-weighted purpose.
Cylinder jacket installing hole 2 is vertically opened in the middle part of cylinder block body 1, and for installing cylinder jacket, cylinder jacket is one
Cylindrical component, is placed in the cylinder body opening of body, on be fixed by cylinder head.Piston is reciprocating in its endoporus.Should
The axial length of cylinder jacket installing hole 2 is less than or equal to the length of the latter half of cylinder jacket, only undertakes cylinder jacket the latter half
Install, and center deviation crankshaft center 10mm of cylinder jacket installing hole 2.Each cylinder jacket also having cylinder block body 1 is installed
It is provided with fall repeated hole 4, thus reducing the cylinder block body weight of the specific embodiment of the invention between hole 2.
Camshaft installing hole 3 is opened on cylinder block body 1, and orthogonal with the axial direction of cylinder jacket installing hole 2, for installing
Camshaft, camshaft is a part in piston engine.Its effect is unlatching and the closed action controlling valve.
To sum up, this cylinder block is passed through to omit water sleeve tappet pore structure so as to casting technique is simple, and lightweight, only
Undertake the output par, c intensity of whole machine, highly low, and reduce the wall thickness in skirt section, reduce body weight further, reach lightweight
Purpose.
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
