Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of motor car engine, particularly a kind of valve retainer for automobile engine mounting structure.
Background technique
Motor is the heart of automobile, for the walking of automobile provides power, is being related to power character, Economy, the feature of environmental protection of automobile.The most basic principle of motor is that the heat energy of gasoline (diesel oil) or rock gas passes through the burning in sealing cylinder, makes to promote piston work done after gas expansion, thereby changes the required mechanical energy of Automobile drive into.All structures of motor, all for transformation of energy is served, wherein just comprise the air valve seat ring being arranged in cylinder head.In engine working process, the effect that air valve seat ring has sealed air valve and transmits valve heat, the design of air valve seat ring mounting structure can affect the power performance of whole motor.
About the design of engine valve retainer mounting structure, people have proposed improvement project miscellaneous.As Chinese patent [application number 201110101176.2; Notice of authorization CN102748086A] disclosed a kind of air valve seat ring mounting structure, comprise cylinder head, be arranged on the precasting air valve seat ring that air flue in cylinder head and air flue and engine chamber junction point set in advance.Above-mentioned air valve seat ring mounting structure adopts the mode of precasting air valve seat ring to omit the course of working in air valve seat ring hole, has reduced cost of production, has improved heat transfer efficiency.
But there is following problem in above-mentioned air valve seat ring mounting structure: in the time of engine work, valve can carry out regularity to air valve seat ring and clash into.Because the hardness of air valve seat ring is greater than cylinder head hardness, cylinder head and air valve seat ring junction point easily deform, and cause valve blow-by, thereby have affected the power performance of motor.Meanwhile, in the time detecting the wear extent of air valve seat ring by measurement valve clearance, easily produce erroneous judgement.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of engine valve retainer mounting structure, and the problem that the utility model solves is the amount of deformation of the surface of contact that how to reduce cylinder head and air valve seat ring generation while being impacted.
The purpose of this utility model can realize by following technical proposal: a kind of valve retainer for automobile engine mounting structure, described motor comprises cylinder head and air valve seat ring, this mounting structure comprises the mounting hole being positioned in cylinder head, described air valve seat ring is embedded in mounting hole, it is characterized in that, on described mounting hole inwall, be fixed with steel bushing, described air valve seat ring is resisted against on steel bushing.
In the time of engine work, valve can clash into repeatedly to the air valve seat ring being embedded in mounting hole.Owing to being provided with steel bushing on mounting hole inwall, the upper-end surface of air valve seat ring is resisted against on steel bushing, in the time that air valve seat ring is subject to clashing into, steel bushing has played the effect of buffering percussive force, so just effectively reduce the distortion that mounting hole produces because being subject to the extruding of air valve seat ring, thereby ensure the seal of engine chamber, improved the performance of motor.
In above-mentioned valve retainer for automobile engine mounting structure, described mounting hole inwall and steel bushing outer wall are fused.When cylinder head casting, precasting steel bushing on the inwall of mounting hole, mounting hole inwall and steel bushing outer wall are fitted completely like this, can not produce gap between steel bushing and mounting hole, make the seal of engine chamber better; Meanwhile, the requirement of steel bushing outer wall effects on surface roughness reduces, and has reduced difficulty of processing, has improved manufacturing efficiency.
As another kind of scheme, in above-mentioned valve retainer for automobile engine mounting structure, described steel bushing is embedded in mounting hole, described steel bushing and mounting hole drive fit.Steel bushing adopts friction tight mode to be embedded in mounting hole, coordinates simple; Meanwhile, steel bushing is as a replaceable maintenance of independent part, and easily manufactured.
In above-mentioned valve retainer for automobile engine mounting structure, described steel bushing hardness is greater than cylinder head hardness.The hardness of steel bushing is greater than cylinder head, has effectively improved the intensity that is positioned at mounting hole in cylinder head.
In above-mentioned valve retainer for automobile engine mounting structure, the internal diameter of described steel bushing is 18mm～28mm.
Compared with prior art, the advantage of this valve retainer for automobile engine mounting structure is:
1, in the time that air valve seat ring is subject to valve shock, steel bushing has played the effect of bearing impact force, and has cushioned shock, and the amount of deformation producing when the surface of contact of cylinder head and air valve seat ring is impacted reduces, ensure the seal of engine chamber, thereby improved the performance of motor.
2, the hardness of steel bushing is greater than cylinder head, has effectively improved the intensity that is positioned at mounting hole in cylinder head, is conducive to reduce the distortion of mounting hole because produced by air valve seat ring extruding.
Brief description of the drawings
Fig. 1 is the utility model valve retainer for automobile engine mounting structure schematic diagram.
In figure, 1, cylinder head; 2, air valve seat ring; 3, mounting hole; 4, steel bushing; 5, valve.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Embodiment one:
This valve retainer for automobile engine mounting structure comprises mounting hole 3 and steel bushing 4.
Specifically, as shown in Figure 1, mounting hole 3 is positioned in cylinder head 1, air valve seat ring 2 is embedded in mounting hole 3, when cylinder head 1 is cast, on the inwall of mounting hole 3, be precast with steel bushing 4, air valve seat ring 2 is resisted against on mounting hole 3, mounting hole 3 inwalls and steel bushing 4 outer walls are fitted completely, between steel bushing 4 and mounting hole 3, can, because relative displacement produces gap, not improve the seal of engine chamber, the requirement of steel bushing 4 outer wall effects on surface roughness simultaneously reduces, reduce difficulty of processing, improved manufacturing efficiency.
Valve 5 is located in mounting hole 3, and in the time of engine work, valve 5 can clash into repeatedly to the air valve seat ring 2 being embedded in mounting hole 3.Air valve seat ring 2 is subject to the effect meeting of impact force mounting hole 3 is pushed, and because air valve seat ring 2 is resisted against on steel bushing 4, the hardness of steel bushing 4 is greater than cylinder head 1 hardness simultaneously, steel bushing 4 has effectively replaced original cylinder head 1 to play the effect of bearing impact force, and cushioned shock, so just effectively reduce the distortion that mounting hole 3 produces because being subject to the extruding of air valve seat ring 2.In addition, the internal diameter preferred value of steel bushing 4 is 20mm.
