Description

IC engine cylinder head
The present invention relates to the cylinder head of internal-combustion engine, it is provided with a cylinder head base at least in the cylinder head body, is furnished with a gas port in this bottom surface at least in advance, and cylinder bottom surface and cylinder head body are made up of unlike material.
Learn that by EP 0 120 223 A2 this cylinder head is made up of the cylinder head base that a circular sheet material that is pressed in the cylinder head body constitutes.The flat board of making by sintering method can play the effect of heat insulating component.In this structure of being made up of compound slab basically, its valve seat can be formed from steel.
In addition, by US 4,774, as can be known, the combined type cylinder head that internal-combustion engine is used is made of two parts in 912 patents, and this cylinder is stamped a cylinder head base that connects with the cylinder head body.Its cylinder head base is by making than the higher material of cylinder head body intensity.
These cylinder heads are with the structure of cylinder head base split, can cause that in some cases being connected between cylinder head base and the cylinder head body produces loosening defective.
Task of the present invention is, avoids this type of shortcoming, and the cylinder head base of this type is improved design, makes the attachment security between cylinder head base and its body reliable, does not produce to get loose.
Do like this according to the present invention: the cylinder head base will be provided with a shaping at least and inlay join domain, and the casting of cylinder head base is annotated in body.Just can make by this method that realizing between cylinder head base and the body is shaped to inlay is connected, like this, avoid connecting loosening, prolong operating life.
Shaping is inlayed join domain and is provided with a projection and/or a recess at least at the edge of cylinder head base, so just realizes especially easily connecting reliably.Inlay Element Design if be shaped and circularize, then this structure just seems simple especially on making.
To consider at this, will design a shaping at the position of cylinder head base and inlay join domain.In the fringe region of combustion chamber side and the gas port zone in the cylinder head bottom surface, can continue to make to be shaped and inlay join domain.Inlaying join domain around this shaping of gas port is in order to prevent sewing of oil.
A kind of splendid improvement project is: the cylinder head bottom surface is made by homogenous material, and valve seat is arranged on the cylinder head base, can cancel demountable air valve seat ring thus.So just can make the spacing between the gas port in the cylinder head base, littler than the spacing that adopts the valve base coil structures.This improved method can make the gas port cross section design more basically.The maximum comparable original area of its cross section increases 50%.
It is also conceivable that in structure of the present invention: the cylinder head base is provided with an opening that leads to the member of firing chamber at least, and this member mainly is spark plug or oil sprayer, and the cover that is used for fastening assembling set can be made of one with the cylinder head base.Part of packing into such as spark plug and or oil sprayer, can directly be fixed on the cylinder head base thus.
If have at least a valve guide bushing that is used for the valve guiding to constitute one with the cylinder head base, then this structure is particularly simple on making.Because valve guide bushing can be poured in the cylinder head body with the cylinder head base, and does not need its location measure is claimed.For valve guide bushing is connected reliably with around the cylinder head body, should consider that constituting shaping in the valve guide bushing outside inlays the connection surface, preferably will have a circle flange shape at least.Just can realize being connected between valve guide bushing and the cylinder head base well thus by an arc bridge jumper.
Another splendid advantage is on the structure: cylinder head base and cylinder liner constitute an integral body.Have at least a shaping to inlay join domain by the cylinder liner outside, can make the combination of cylinder liner in body very firm.
The cylinder head base is preferably by the cast iron manufacturing, and for example by having sheet, the grey cast iron of spherical or helical graphite is perhaps formed by the cast steel manufacturing.The cylinder head body can be used light metal, and for example aluminium is made.
The moulding of air flue can produce its wall with punching block.After the cast punching block can be agley or stretching mode by pulling out in the air flue.
The manufacturing of cylinder head is such, the cylinder head base that good ferrous material is made is put in the steel mold, enclose casting together with the cylinder head bulk material, before enclosing casting, want the preheating of countercylinder cover base, also can carry out slight corrosion treatment from the teeth outwards in case of necessity, so that make itself and casting metal material reach good binding.
Below the present invention is described in detail by accompanying drawing, these accompanying drawings are:
Cylinder head base in the oblique drawing after Fig. 1 represents to cut open according to cylinder head of the present invention;
Fig. 2 represents the cylinder head base in the planimetric map;
Fig. 3 is the another kind of oblique drawing of cylinder head base;
Fig. 4 is the side view of cylinder head base;
Fig. 5 is another kind of structural type cuts open the cylinder head of getting along " V-V " line among Fig. 4 a sectional drawing; And
Fig. 6 is the sectional drawing of the cylinder cap of the another kind of structural type of the present invention.
Cylinder head 1 is combined by a body 2 and a cylinder head base 3 that is cast in the body 2.By represent that in cylinder 5, can move back and forth, as to be subjected to a firing chamber 5a restriction piston with reference to figure 4.As shown in Figure 1, this moment, the structure of cylinder head 1 can be regarded cylinder head one cylinder unit as, and cylinder 5 constitutes the cylinder of sealing.In structure shown in Figure 1, it is L shaped piston ring 4a that piston 4 has a cross section, can cancel other compression ring thus.
Cylinder head base 3 has a shaping that is made of annular projection 7 to inlay join domain 6 in its peripheral 3a zone, inlays with cylinder head 1 by this zone cylinder head base 3 to be connected.The cover 8 that is used for that is used for placing an assembling set 9 (such as spark plug or injection valve) constitutes an integral body with cylinder head base 3.The opening portion of assembling set 9 is reference mark 9a.Fringe region 3c near firing chamber 5a around the air flue 14,15 in positive 3b and the cylinder head base 3, has other shaping to inlay join domain 6a and 6b.
Other structural member also is useful on the valve guide bushing 10 of valve 11,12 guiding, and this valve guide bushing constitutes parts with cylinder head base 3.Valve guide bushing 10 has flange shape shaping to inlay to connect surface 16 in its outside, and is connected with cylinder head base 3 by arc bridge jumper 13 separately.
Fig. 5 is cylinder head 1 and cylinder 5 structure during as two parts.
Fig. 6 is another kind of organization plan, and the cylinder sleeve 5c of dress piston 4 is whole in cylinder head base 3 and one constitutes.In order to reach the molding material secure bond with body 2, the outside of cylinder sleeve 5c has annular and is shaped and inlays join domain 6c.
Mark exhaust air flue and air inlet air flue with reference number 14 and 15 respectively in the drawings.At this moment, the wall 14a of this exhaust air flue 14 and air inlet air flue 15,15a also can constitute one with cylinder head base 3.Exhaust air flue 14 and air inlet air flue 15 can adopt the drawing loam core to create in moulding.Finishing the back punching block in cast can be crooked or stretchingly take out from air flue.
Can adopt the grey cast iron of sheet, spherical or helical graphite, perhaps cast steel as the material of cylinder head base 3.Cylinder head 1 can be such as being formed from aluminium.
In order to make cylinder head 1, need prefabricated cylinder head base 3 is carried out preheating, slight corrosion treatment is carried out on the surface, place punching block also to cast with body 2 materials with extrusion process.By to surperficial mild corrosion and The pre-heat treatment, can realize good especially being connected with body 2 metallic material.
