Abstract
The utility model discloses a kind of self-lubricating engine piston, including the piston only made of aluminium alloy, it is characterized in that：It is located at the skirt section with guide function on piston only and is arranged with oil-containing wear-resistant block, oil-containing wear-resistant block is powder metallurgy or graphite material is made and internal immerse has lubricating oil.Beneficial effect is：Oil-containing wear-resistant block is arranged with due to being located at the skirt section with guide function on piston only, oil-containing wear-resistant block is powder metallurgy or graphite material is made and internal immerse has lubricating oil, therefore self-lubricating can be realized, start fricting movement or engine once piston and light piston for the first time to be heated rapidly and when producing temperature, the lubricating oil immersed in oil-containing wear-resistant block will be spilled between piston and cylinder body, ensure there is lubricating oil all the time between piston and cylinder body, avoid because lubricate not in time and caused by engine scuffing of cylinder bore or viscous cylinder, so as to improve engine life.
Description
Technical field
A kind of engine piston is the utility model is related to, more particularly to a kind of self-lubricating engine piston.
Background technology
Piston is the important component on engine, and most of piston is all made of aluminum alloy materials, due to piston itself
Do not possess self-lubricating function, it is therefore necessary to be lubricated by the lubricant medium in engine block.
When engine initialization or vehicle are on the shelf for a long time, or it is temporary transient due to engine motor oil pumping system
Property failure, normal lubrication could be realized by being typically necessary multiple sky and stepping on the gas, and otherwise easily cause the scuffing of cylinder bore of engine and viscous
Cylinder, so as to cause engine failure, unnecessary loss is caused to car owner.
The content of the invention
Technical problem to be solved in the utility model, which is to provide one kind, can realize self-lubricating, ensure piston and cylinder body it
Between have lubricating oil all the time, avoid because of insufficient lubrication or not in time and caused by the scuffing of cylinder bore of engine or the self-lubricating engine of viscous cylinder live
Plug.
The technical solution of the utility model is as follows：
A kind of self-lubricating engine piston, including the piston only made of aluminium alloy, it is characterized in that：On piston only
Be arranged with oil-containing wear-resistant block positioned at the skirt section with guide function, oil-containing wear-resistant block be made for powder metallurgy or graphite material and
Inside, which is immersed, lubricating oil.
As further preferred, the oil-containing wear-resistant block is inlayed or die casting is on piston only, is connected into piston only
One.
As further preferred, fan-shaped cross section for the oil-containing wear-resistant block.
As further preferred, compression, frizing annular groove, oil ring groove are from top to bottom equipped with successively in piston only upper end,
It is respectively used to installation compression ring, oil-scraping ring and oil ring.
As further preferred, multiple oilholes, oilhole are along the circumferential direction laid with oil ring groove on piston only
Connect oil ring groove and piston only inner cavity.
The beneficial effects of the utility model are：It is arranged with due to being located at the skirt section with guide function on piston only
Oil-containing wear-resistant block, oil-containing wear-resistant block is powder metallurgy or graphite material is made and internal immerse has lubricating oil, therefore can realize
Self-lubricating, starts fricting movement or engine and lights piston for the first time to be heated rapidly and when producing temperature, oil-containing is resistance to once piston
The lubricating oil immersed in abrading block will be spilled between piston and cylinder body, ensured there is lubricating oil all the time between piston and cylinder body, kept away
Exempt from because lubricate not in time and caused by engine scuffing of cylinder bore or viscous cylinder, so as to improve engine life.
Brief description of the drawings
Fig. 1 is the structure sectional view of the utility model.
Fig. 2 is the A-A sectional views of Fig. 1.
In figure：Piston only 1, oil-containing wear-resistant block 2, oil ring groove 3, frizing annular groove 4, compression 5, oilhole 6, hinge hole 7.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
The all other embodiment obtained, shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, a kind of self-lubricating engine piston that the utility model is related to, including by aluminum alloy materials
The piston only 1 that die casting forms, the skirt section that being located on piston only 1 has guide function are arranged with oil-containing wear-resistant block 2, contain
Oily wear-resistant block 2 is powder metallurgy or graphite material is made and there is lubricating oil in inside by vacuumizing high temperature and pressure and immersing.It is described to contain
Oily wear-resistant block 2 is inlayed or die casting is on piston only 1, and is linked into an integrated entity with piston only 1.
Fan-shaped cross section for the oil-containing wear-resistant block 2.1 upper end of piston only from top to bottom successively be equipped with compression 5,
Frizing annular groove 4, oil ring groove 3, are respectively used to installation compression ring, oil-scraping ring and oil ring.
Along the circumferential direction be laid with multiple oilholes 6 in the oil ring groove on piston only 1, oilhole 6 connect oil ring groove 3 with
1 inner cavity of piston only.Hinge hole 7 is arranged with 1 lower lumen both sides of piston only, for Hinged piston bar.
During work, when self-lubricating engine piston setting in motion in cylinder body, the piston is with inner chamber of cylinder block because of friction
And heat is produced, or when engine lights piston for the first time and is heated rapidly and produces temperature, the fluid inside oil-containing wear-resistant block 2
Will overflow, thus between the piston and inboard wall of cylinder block formed one layer of lubricating oil film, can avoid because lubricate not in time and caused by
The scuffing of cylinder bore of engine or viscous cylinder；When engine at work, oil-containing wear-resistant block 2 can also be absorbed because of the high temperature and pressure of engine interior
A part of fluid, so as to ensure in oil-containing wear-resistant block 2 lubricating oil containing saturation all the time.
Although the embodiment of the utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to the field of various suitable the utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
