Abstract
The invention discloses a kind of cylinder head strengthening base plate rigidity, including cylinder cap body, being provided with some ribs on the water cavity inwall of cylinder cover bottom surface side, this rib is used for coupling together the hole wall of cylinder bolt hole all of in cylinder head respectively with the hole wall of valve retainer hole and the hole wall of mounting hole of oil sprayer.This cylinder-head distortion is less, so that cylinder head gasket can effectively seal, substantially reduces the risk rushing cylinder pad.
Description
Technical field
The present invention relates to cylinder head field, particularly to a kind of cylinder head strengthening base plate rigidity.
Background technology
At present, as it is shown in figure 1, the cylinder head 1 of Diesel engine is fixedly connected on cylinder block 4 by cylinder head bolt 2
Together, cylinder head gasket 3 is placed between cylinder head 1 and cylinder block 4, and final cylinder head bolt 2 is by cylinder head 1, cylinder-top gasket
Sheet 3 and cylinder block 4 three fastening.
Available engine often occurs that cylinder cap rushes the hidden danger of cylinder pad, due to discharge upgrading, makes the rising of electromotor detonation pressure, merit
Rate promotes, and external feedback constantly occurs that batch rushes the fault of cylinder pad.Follow-up raising cylinder pad performance of passing through the most not can solve punching
Cylinder pad fault.By detecting returning factory's fault machine correlated parts, find that cylinder head soffit plane degree is overproof, cylinder head bottom surface
Deformation is serious, and cylinder head gasket cannot make up the deflection of cylinder head bottom surface, thus causes rushing cylinder pad.
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
When being considered to recognize or imply in any form this information structure prior art well known to persons skilled in the art.
Summary of the invention
It is an object of the invention to provide a kind of cylinder head strengthening base plate rigidity, cylinder-head distortion is less, so that gas
Gland shim can effectively seal, and substantially reduces the risk rushing cylinder pad.
For achieving the above object, the invention provides a kind of cylinder head strengthening base plate rigidity, including cylinder cap body, leaning on
The water cavity inwall of nearly cylinder cover bottom surface side is provided with some ribs, and this rib is used for cylinder bolt hole all of in cylinder head
Hole wall couples together with the hole wall of valve retainer hole and the hole wall of mounting hole of oil sprayer respectively.
Compared with prior art, there is advantages that by cylinder bolt hole and valve retainer hole, spray
It is connected with rib between the hole wall of oil device installing hole, reaches the structure of similar roof house beam, be greatly improved cylinder head base plate
Rigidity so that electromotor, when normally working, reduces the deformation of cylinder cap, substantially reduces the risk rushing cylinder pad.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of existing cylinder head；
Fig. 2 is the sectional view of the cylinder head strengthening base plate rigidity according to the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Scope of protecting is not limited by detailed description of the invention.
Explicitly indicating that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or it becomes
Change and such as " comprising " or " including " etc. will be understood to comprise stated element or ingredient, and do not get rid of other yuan
Part or other ingredient.
As in figure 2 it is shown, according to a kind of cylinder head strengthening base plate rigidity of the specific embodiment of the invention, including cylinder cap originally
Body, is being provided with some ribs 13 on the water cavity inwall of cylinder cover bottom surface side, and this rib 13 is used for all of in cylinder head
The hole wall of cylinder bolt hole 14 couples together with the hole wall of valve retainer hole 11 and the hole wall of mounting hole of oil sprayer 12 respectively.
In such scheme, mainly cylinder head internal structure is made change, for cylinder combustion cylinder cover bottom surface spot temperature
Higher, and during by burning, explosion pressure is affected, by cylinder bolt hole 14 and valve retainer hole 11, mounting hole of oil sprayer
It is connected with rib between the hole wall of 12, reaches the structure of similar roof house beam, strengthen the rigidity of cylinder head burning heated part.Logical
After crossing the improvement of this reinforcement cylinder head base plate rigidity, cylinder head, when engine work, deforms less, so that cylinder
Lid gasket can effectively seal, and substantially reduces the risk rushing cylinder pad.The cylinder head of this structure criticizes product the most in a large number at present.
As a kind of preferred embodiment, the water cavity inwall within cylinder cap can carry out local and thicken 2～5mm designs,
Can local enhancement rigidity further.
To sum up, the cylinder head strengthening base plate rigidity of the present embodiment, by cylinder bolt hole 14 and valve retainer hole 11,
It is connected with rib between the hole wall of mounting hole of oil sprayer 12, reaches the structure of similar roof house beam, be greatly improved at the bottom of cylinder head
The rigidity of plate so that electromotor, when normally working, reduces the deformation of cylinder cap, substantially reduces the risk rushing cylinder pad.Relative to
For improving cylinder-top gasket piece performance, cost is more lower, and reliability is higher.
The aforementioned description to the specific illustrative embodiment of the present invention illustrates that and the purpose of illustration.These describe
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 change
And change.The purpose selected exemplary embodiment and describe is to explain that the certain principles of the present invention and reality thereof 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 equivalents thereof.
Claims (1)
1. strengthen a cylinder head for base plate rigidity, including cylinder cap body, it is characterised in that at the water near cylinder cover bottom surface side
