Abstract

The invention discloses a cylinder cover assembly. The cylinder cover assembly comprises a cylinder cover body and an air inlet pipe hood, wherein a first open long cavity is integrally cast on the air inlet side of the cylinder cover body, and the first long cavity forms part of an air inlet pipe of an air inlet manifold; and the air inlet pipe hood is provided with a second open long cavity, and the first long cavity and the second long cavity are buckled to form an air inlet cavity of the air inlet manifold. According to the cylinder cover assembly, part of the structure of the air inlet manifold is integrated on a cylinder cover, and the independent air inlet pipe hood serves as the other part of the structure of the air inlet manifold so that integrated design can be guaranteed, system weight can be reduced, and the manufacturability of cylinder covers is optimized.

Description

Cylinder head assembly
Technical field
The present invention relates to field of internal combustion engine, particularly to a kind of cylinder head assembly.
Background technology
Field of internal combustion engine now, market proposes various requirements to electromotor.Especially in cost and weight etc. Aspect, increasingly lower engine price and engine weight, are all a kind of test to All hosts factory.
Existing engine cylinder cap, with the design of increasing part integrated form, the arrangement form of cylinder head is more next More complicated.And more complicated cylinder head form, it is poor to result in its casting manufacturability, manufactures difficult, high cost.More typically have gas Cylinder cap and inlet manifold carry out integrated form design, and the cylinder head part volume of this kind of Integrated design itself is larger, and structure is more complicated, Casting weight is big, and casting manufacturability is also poor.In addition, for the cylinder cap sand removal to integrated casting, and air intake duct shot blasting on surface Process it is necessary to process some sand cleaning holes, also covert increased cost.
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 cylinder head assembly, the part-structure of inlet manifold is integrated on cylinder cap, Another part structure of inlet manifold is provided by independent air inlet shroud, both can guarantee that Integration Design, and can reduce system weight again Amount, optimizes the anufacturability of cylinder head.
For achieving the above object, the invention provides a kind of cylinder head assembly, a kind of cylinder head assembly, including:Cylinder cap is originally Body, the air inlet side integrally casting of cylinder cap body has the first unlimited long-shaped cavity, and this first long-shaped cavity forms inlet manifold Partial-air admission tube capacity amasss;And air inlet shroud, air inlet shroud has the second unlimited long-shaped cavity, the first long-shaped cavity and second Long-shaped cavity fastens the air inlet die cavity forming inlet manifold.
Preferably, the end face seal of the open end of the end face of the open end of the first long-shaped cavity and the second long-shaped cavity connects Connect.
Preferably, on the air inlet shroud of the second long-shaped cavity dorsal part, there is air inlet.
Compared with prior art, the present invention has the advantages that:By integrated intake manifold part-structure in cylinder On lid body, compared to the cylinder head assembly of over all Integration inlet manifold, casting manufacturability is good, and system overall weight is light, structure Simply, low cost of manufacture.And it is completely independent design compared to more conventional cylinder head assembly, inlet manifold, half integrated air inlet pipe Air inlet shroud required for the air cylinder head structure of formula, structure is very simple, can adopt rheo-die-casting molding, compared to conventional Gas inlet manifold design, easy to manufacture, low cost.
Brief description
Fig. 1 is the structural representation according to cylinder head body in the cylinder head assembly of the present invention;
Fig. 2 is the structural representation according to air inlet shroud in the cylinder head assembly of 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 ingredient, and do not exclude other units Part or other ingredient.
As depicted in figs. 1 and 2, a kind of cylinder head assembly according to the specific embodiment of the invention, including cylinder cap body 1 with And air inlet shroud 2, the air inlet side integrally casting of cylinder cap body 1 has the first unlimited long-shaped cavity 11, this first long-shaped cavity 11 The partial-air admission tube capacity forming inlet manifold amasss, and air inlet shroud 2 has the second unlimited long-shaped cavity 21, the first long-shaped cavity 11 and the second long-shaped cavity 21 fasten formed inlet manifold air inlet die cavity.
As a kind of preferred embodiment, the opening wide of the end face of open end of the first long-shaped cavity 11 and the second long-shaped cavity 21 The end face seal at end connects.
As a kind of preferred embodiment, the air inlet shroud 2 being in the second long-shaped cavity 21 dorsal part has air inlet 22.
In such scheme, by the cylinder head being integrated with admission manifold branch structure being split into two parts it is ensured that cylinder head Casting manufacturability good, second half inlet manifold being simultaneously split away using design of materials such as die casting aluminium or engineering plastics (air inlet shroud 2), reduces the weight of whole system.Split out two of the above-mentioned cylinder head being integrated with admission manifold branch structure Point, Part I structure is exactly the cylinder cap body 1 described by the present embodiment, and it is only integrated with partial-air admission manifold on cylinder cap, Air inlet side remains with a larger cavity.This cavity is just considered as the air inlet pipe volume of a part.And split separate Part II, then be the very simple air inlet shroud 2 (referring to Fig. 2) of a structure, two parts are by a machining plane Laminating, sealing forms air inlet die cavity.
To sum up, the cylinder head assembly of the present embodiment, by integrated intake manifold part-structure on cylinder head body, compares In the cylinder head assembly of over all Integration inlet manifold, casting manufacturability is good, and system overall weight is light, and structure is simple, manufacturing cost Low.And it is completely independent design compared to more conventional cylinder head assembly, inlet manifold, partly it is integrated into the air cylinder head structure of air-tube type Required air inlet shroud 2, structure is very simple, can adopt rheo-die-casting molding, compared to conventional gas inlet manifold design, Easy to manufacture, low cost.
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.
