Abstract
The invention discloses a kind of overhead camshaft cylinder head, a part of cam shaft installing seat hole and cylinder holes is integrated in the overhead camshaft cylinder head, the intensity of the overhead camshaft cylinder head is significantly increased, and can bear higher explosion pressure, and structure simply reduces cost.
Description
Technical field
The present invention relates to field of internal combustion engine, especially with regard to a kind of overhead camshaft cylinder head.
Background technique
Cylinder head is a key components and parts of conventional internal combustion, and cylinder block, cylinder jacket form internal combustion together
The basic framework of machine.Specifically, cylinder head is installed on cylinder block by cylinder head bolt, and cylinder jacket is installed on cylinder block
In cylinder-bore (cylinder-bore for the internal combustion engine having is for being mounted directly piston), cylinder head and piston, cylinder jacket form internal combustion engine
Combustion chamber, piston is reciprocating in cylinder jacket.
Conventional internal combustion cylinder head is installed on cylinder block by cylinder head bolt, between cylinder head and cylinder block
It is sealed by head gasket, cylinder head bolt tightens rear bolt pulling force and cylinder head and cylinder block compress head gasket, cylinder jacket
(cylinder-bore for the internal combustion engine having is for being mounted directly piston), cylinder head, head gasket, gas are installed in the cylinder-bore of cylinder block
The burning confined space of cylinder sleeve (or cylinder block) and piston composition internal combustion engine, the pressure that fuel oil is generated in gas in-cylinder combustion are usual
It is higher, need cylinder to be stamped enough intensity.The pressure generated when near top dead center fuel oil is in gas in-cylinder combustion is maximum, cylinder
Lid bottom surface is heated, stress modification is serious, is easy to cause cylinder cap to split, rushes the failures such as cylinder pad.
General cylinder head is in cuboid, and rigid better, the stress modification of the cylinder head that general height is higher, width is smaller is more
It is small, it is able to bear the higher detonation pressure that burning generates；Conventional internal combustion cylinder head is since by height limitation, size is more flat
Flat, structural strength is low, detonation pressure in unbearable higher cylinder, while structure bulky, using cast iron materials；In addition, conventional internal combustion
Engine cylinder cap is sealed using bolt, cylinder head gasket structure, detonation pressure in unbearable higher cylinder, and detonation pressure height is easy to appear in cylinder
Cylinder cap splits, rushes the failures such as cylinder pad；And conventional internal combustion cylinder head wheel shaft is mounted in cylinder head by camshaft cover, knot
Structure is complicated, number of parts is more, and processing is complicated and installation positioning requirements are higher.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Summary of the invention
The purpose of the present invention is to provide a kind of overhead camshaft cylinder head, and the intensity of the overhead camshaft cylinder head is substantially
Increase, higher explosion pressure can be born, and structure simply reduces cost.
To achieve the above object, the present invention provides a kind of overhead camshaft cylinder head, the overhead camshaft cylinder head
On be integrated with a part of cam shaft installing seat hole and cylinder holes, which is integrated in the overhead camshaft gas
On cylinder cap, does not need camshaft cover, shaft-cup positioning sleeve and bolt and be mounted in cylinder head, structure simply reduces cost.
In a preferred embodiment, cylinder holes water jacket is also integrated in the overhead camshaft cylinder head.
In a preferred embodiment, the cam shaft installing seat hole uses tunnel structure to be integrated in the overhead convex
In wheel shaft cylinder head, without camshaft cover processing being dismounted for multiple times positioning, machining accuracy is high.
In a preferred embodiment, the height of the overhead camshaft cylinder head is at least 2 times of width, so that
Cylinder head intensity is significantly increased, and can bear higher explosion pressure.
In a preferred embodiment, the overhead camshaft cylinder head uses casting aluminium material, can satisfy engine
Engine weight is greatly lowered in strength demand.
Compared with prior art, overhead camshaft cylinder head of the present invention has the following beneficial effects:
The present invention provides a kind of overhead camshaft cylinder head, and cam shaft installing seat hole is integrated on cylinder cap, to subtract
Few number of parts, reduces engine cost, in addition, cylinder holes water jacket and part cylinder holes are integrated on cylinder cap, so that cylinder head
Intensity is high, and the demand of high detonation pressure is just able to satisfy using cast aluminum construction, engine cylinder cap weight is greatly reduced, for engine
High-intensitive, integrated, light-weight design has good help.
Detailed description of the invention
Fig. 1 is overhead camshaft air cylinder head structure schematic diagram according to an embodiment of the present invention.
Main appended drawing reference explanation:
1- cam shaft installing seat hole, 2- cylinder holes, 3- cylinder holes water jacket.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, overhead camshaft cylinder head according to the preferred embodiment of the present invention, the overhead camshaft cylinder
The a part for being integrated with cam shaft installing seat hole 1 and cylinder holes 2 is covered, it is convex which is integrated in the overhead
In wheel shaft cylinder head, do not need camshaft cover, shaft-cup positioning sleeve and bolt and be mounted in cylinder head, structure simply reduce at
This.
As a kind of preferred embodiment, cylinder holes water jacket 3 is also integrated in the overhead camshaft cylinder head.
As a kind of preferred embodiment, it is convex that the cam shaft installing seat hole 1 uses tunnel structure to be integrated in the overhead
In wheel shaft cylinder head, without camshaft cover processing being dismounted for multiple times positioning, machining accuracy is high.
As a kind of preferred embodiment, the height of the overhead camshaft cylinder head is at least 2 times of width, so that cylinder
Lid intensity is significantly increased, and can bear higher explosion pressure.
As a kind of preferred embodiment, the overhead camshaft cylinder head uses casting aluminium material, and it is strong to can satisfy engine
Degree demand, is greatly lowered engine weight.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate 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 the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining specific principle of the invention and its actually answering
