Description
Technical field
The utility model relates to technical field of engines, particularly relates to a kind of engine air cylinder cap.
Background technology
Currently, valve actuating mechanism is the core on engine, and camshaft is the important component part of valve actuating mechanism.Pass
The engine of system relies on camshaft-bearing cap to prevent circular runout in running for the camshaft and axial float.And use
The sealing gasket of valve mechanism cover end face and cylinder head form airtight space, the valve actuating mechanism of engine can be sealed in this airtight
In space, serve the purposes such as dust-proof, sealing, noise reduction.
In prior art, valve mechanism cover is formed by aluminium die cast, then improves precision by machining again.
So, current valve mechanism cover mostly is the shelly part of thin-walled, and their intensity is not very high, and at valve mechanism cover and gas
When cylinder cap is installed, the area for valve mechanism cover contact is also very limited, and then causes sealing not enough phenomenon, is easily caused machine oil
Leak from the contact surface between valve mechanism cover and cylinder head.
Utility model content
The technical problems to be solved in the utility model is, overcomes existing technological deficiency, provides a kind of valve mechanism cover intensity
The engine air cylinder cap of higher and better tightness.
Technical solution of the present utility model is to provide a kind of engine air cylinder cap with following structure: include
For the housing body being connected with cylinder head, housing body is provided with multiple installing hole, and housing body outer wall is provided with flat board, flat
Plate and this body by integral forming of housing；The outer wall of housing body is provided with multiple reinforcement, and reinforcement is along housing body height direction
Arrange, and multiple reinforcement is distributed around housing body circumferentially-spaced；On housing body, the surface for contacting with cylinder head is provided with
Annular groove, the shape of annular groove is consistent with the profile of housing body, and is embedded with on annular groove for connecing with cylinder head
The sealing ring touching；It is welded with metallic plate on the inwall of described housing body.
The utility model can strengthen the intensity of housing body upper surface by the setting of flat board, improves table on housing body
The bearing capacity in face, even if housing body upper surface places the article of constant weight, does not interferes with the normal of housing body yet
Work；And the intensity of this body sidewall of housing can be improved by the setting of reinforcement, prevent this body sidewall of housing due to housing originally
Body upper surface stand under load is excessive and deforms；In addition, pass through the cooperation of annular groove and sealing ring so that housing body and cylinder
After lid assembling finishes, sealing ring can contact with housing body, cylinder head simultaneously, so that the knot of housing body and cylinder head
There is not gap in conjunction face place, and then improves the sealing that housing body is connected with cylinder head；Further, by housing inner body wall
Metallic plate is set and can improve the intensity in local for the housing body, increase the wall thickness in local for the housing body.Therefore, this practicality is new
Type provides a kind of valve mechanism cover intensity higher and the engine air cylinder cap of better tightness.
Preferred as one, described annular groove is the loop configuration closed.Preferred by this, an envelope can be formed
The loop configuration closed, thus for sealing ring setting-in, and then when housing body is finished with cylinder head assembling, sealing ring is squeezed
Gap at housing body and cylinder head faying face is kept to zero by deformation.
Preferred as one, the inwall of described housing body is provided with multiple pad.Preferred by this, can improve
The intensity of housing body local so that the bearing capacity of housing body local is higher, and pad is arranged on housing body
The outward appearance of housing body is not also interfered with so that the outer wall of housing body keeps smooth on inwall.
Preferred as one, described reinforcement is string configuration, and reinforcement upper end is connected with housing body upper surface,
Lower end is connected with housing body lower surface, and reinforcement and this body by integral forming of housing.Preferred by this so that housing body exists
Whole short transverse can be strengthened the support of muscle, improves the intensity of whole housing body.

Detailed description of the invention
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
The utility model engine air cylinder cap includes, for the housing body 1 being connected with cylinder head, housing body 1 setting
Have multiple installing hole 2, described installing hole 2 be used to mount point fire coil, pressure control valve, camshaft and for cylinder head
The bolt connecting, the size and shape of multiple installing holes 2 can be different, and can arrange not on the installing hole 2 of difference in functionality
Same structure, such as, the installing hole 2 for installing camshaft can be used for positioning camshaft with setting table terrace；Lid
Cover body 1 outer wall is provided with flat board 3, and flat board 3 is arranged on the upper surface of housing body 1, and flat board 3 is one-body molded with housing body 1,
It is similar to set up a boss for strengthening housing body 1 upper surface intensity at the upper surface of housing body 1；Housing body 1
Outer wall be provided with multiple reinforcement 4, reinforcement 4 along housing body 1 short transverse arrange, and multiple reinforcement 4 around housing this
Body 1 circumferentially-spaced is distributed；On housing body 1, the surface for contacting with cylinder head is provided with annular groove 5, the shape of annular groove 5
Shape is consistent with the profile of housing body 1, and is embedded with the sealing ring for contacting with cylinder head on annular groove 5；Described lid
It is welded with metallic plate 6 on the inwall of cover body 1.
Described annular groove 5 is the loop configuration closed, and, the sealing ring being inlaid in annular groove 5 is also envelope
The loop configuration closed, thus may insure that the gap at housing body 1 and cylinder head contact surface is zero.
The inwall of described housing body 1 is provided with multiple pad 7, and these pads 7 are distributed in housing body 1
Inwall on, and each pad 7 is positioned close to the position of installing hole 2, as it is shown on figure 3, thus can improve installing hole 2
The intensity at place, it is to avoid installing hole 2 is concentrated due to stress with housing body 2 junction and rupture or fracture are occurred.
