Description
Technical field
The present invention relates to the technical field of internal combustion engine part, in particular it relates to which a kind of couple multiple-piece piston-ring and piston are total
Into.
Background technology
Piston ring is to enter becket inside piston groove for down, piston ring be it is a kind of have larger expand outwardly deformation
Metallic elastic ring, it is mounted in its corresponding annular groove of section, and reciprocal and rotary motion piston ring, dependence
The pressure differential of gas or liquid, sealing, piston ring are formed between ring periphery and a side of cylinder and ring and annular groove
It is the core component inside fuel engines, it and cylinder, piston, cylinder wall etc. completes the sealing of fuel oil-gas together.
Piston ring effect includes four sealing, regulation machine oil (oil-control), heat conduction (heat transfer), guiding (supporting) effects.
Sealing:Refer to sealing combustion gas, do not allow the gas of combustion chamber to drain to crankcase, the leakage rate of gas is controlled in minimum
Degree, improve the thermal efficiency.Gas leakage can not only make the power dropping of engine, and machine oil can be made to go bad, and this is that the main of compression ring is appointed
Business；
Adjust machine oil (oil-control):Lubricating oil unnecessary on cylinder wall is scraped, while makes to be furnished with very thin oil on casing wall again
Film, ensure cylinder and the normal lubrication of piston and ring, this is the main task of oil ring.It is especially heavy in modern high-speed engines
Depending on the effect of piston ring control oil film；
Heat conduction:The heat of piston is conducted to by cylinder sleeve by piston ring, that is, plays cooling effect.Think according to reliable data, it is living
There are 70~80% to be transmitted to casing wall by piston ring to dissipate in the suffered heat in plug top；
Supporting:Piston ring keeps piston in the cylinder, to prevent piston from directly contacting with cylinder wall, ensures piston smooth-going fortune
It is dynamic, frictional resistance is reduced, and prevent piston knock.
Existing piston ring on the market be with endless metal ring jaggy, the structure of piston ring also can directly Baidu enter
Row understands, and in general, needs to install 4 such piston rings on the piston rod of a cylinder, 4 piston rings are along piston rod
Length direction is spaced.
Following defect be present in existing piston ring：
1st, piston ring can not realize the completely enclosed of cylinder interior gas, also have breach stream of a small amount of gas through piston ring
Into crankcase, so as to cause combustion engine powered leakage；
2nd, due to being exactly that piston ring probably needs four so that the contact area of piston ring and cylinder inner wall is very big, causes
Abrasion between the two is very big, greatly reduces the service life of piston ring and cylinder；
3rd, the temperature in crankcase is too high, so as to influence the lubrication viscosity of machine oil；
4th, particulate accumulation is formed because the burning of oil produces molecule, abrasion of the machine oil muddiness to inner body causes to damage
Consumption, influence the service life of machine oil and part.
The content of the invention
To be realized in order to solve the above technical problems, the invention provides a kind of couple multiple-piece piston-ring and piston assembly with reaching
Completely enclosing for cylinder interior gas is muddy internally improving power, extending the service life of piston ring and cylinder and reducing machine oil
The abrasion of portion's part causes loss, and to extend the purpose of the service life of machine oil and part, solving existing piston ring can not be real
The completely enclosed service life for causing combustion engine powered leakage, abrasion to reduce very much piston ring and cylinder greatly of existing cylinder interior gas
And abrasion of the machine oil muddiness on inner body the problem of causing loss to influence the service life of machine oil and part.
In order to realize above-mentioned technique effect, technical scheme provided by the present invention is：A kind of couple multiple-piece piston-ring and work
Fill in assembly, including piston, the couple multiple-piece piston-ring that is installed on piston, the couple multiple-piece piston-ring include main piston ring and
Auxiliary piston ring, the main piston ring and auxiliary piston ring are equipped with opening, and the opening of the main piston ring and the auxiliary piston ring
Opening between in dislocation assembling；The section of the main piston ring is step type, and the cascaded surface of main piston ring is located at main piston ring
Excircle side；The rectangular cross-section of the auxiliary piston ring, and auxiliary piston ring adaptation is installed on the main piston ring；It is described
Offered on piston for assembling the annular groove of the couple multiple-piece piston-ring, and offered in the side wall of annular groove and its
Concentric pressing groove and pressing groove are located at the side where main piston ring large end face, and the mounted inside of pressing groove has pressure ring spring.
Further, the distance between large end face of the cascaded surface of the main piston ring and main piston ring is equal to main piston ring
The distance between the small end face of cascaded surface and main piston ring.
Further, the radial width of the small end face of the main piston ring is the radial width of the large end face of main piston ring
A quarter.
Further, set between the opening and the opening of the auxiliary piston ring of the main piston ring in staggering 180 °.
Further, the main piston ring inside the annular groove is assemblied in the top of auxiliary piston ring, and the pressure ring bullet
Spring is pushed against in the top of the main piston ring.
Compared to prior art, the beneficial effects of the invention are as follows：
1st, burning gases can be blocked so that it cannot be introduced into crankcase, improve power, reduce oil consumption；
2nd, the temperature of crankcase can be reduced, so as to increase the lubrication viscosity of machine oil；
3rd, the molecule in gas can be blocked to enter crankcase, prevented the accumulation of molecule substantially, added machine
The service life of oil and engine；
4th, piston ring of the invention only needs one to achieve that to be fully sealed so that contact of the piston ring with cylinder inner wall
Area greatly reduces, and reduces abrasion between the two, substantially increases both service life, it is possible to reduce exhaust emissions；
5th, the present invention is by special piston, pressure ring spring, main piston ring and auxiliary piston ring is supporting forms combined assembly, this assembly
The loss of abrasion to internal combustion engine, power, oil consumption, cylinder and crankcase, particularly machine oil, the energy-conservation advocated for country subtract
Row has the lifting of matter.
