Environment in, sheared and impulsive force simultaneously, common piston pin is typically all the cylindrical bearing pin of hollow,
In the pin-and-hole of assembling piston skirt, play connection piston and the effect of connecting rod.Although piston pin technology is
Comparative maturity, but the piston pin of conventional structure can not meet novel structure, designs level cleverly
Opposed cylinder opposed pistons (OPOC) form engine structure requirement.
Summary of the invention
It is an object of the invention to provide the outer piston pin of a kind of internal combustion engine, to solve existing conventional piston pin
The structural requirement problem of horizontally-opposed cylinder opposed pistons (OPOC) electromotor cannot be met.
To achieve these goals, the technical scheme that the present invention takes is:
The outer piston pin of a kind of internal combustion engine, wherein, including an outer piston pin and be positioned at described outer piston pin two
The plug of side, and one with described outer piston pin Matching installation inner carrier pin on external internal combustion engine.
The outer piston pin of above-mentioned a kind of internal combustion engine, wherein, described outer piston pin be shaped as " T " word
Type, the both sides of the described outer piston pin described plug of installation are also respectively provided with and increase the cylindrical pin of lubricant effect
Axle, each described bearing pin is provided with the plane for increasing lubricating contact face, and offers footpath in described plane
To oilhole.
The outer piston pin of above-mentioned a kind of internal combustion engine, wherein, each described bearing pin also has an axial oil
Hole, described plug matches with described axial oilhole, and described plug constitutes shoe cream room after installing.
The outer piston pin of above-mentioned a kind of internal combustion engine, wherein, the centre of described bearing pin has Baking soda, institute
Stating radial direction oil hole goes Baking soda to be connected with described.
The outer piston pin of above-mentioned a kind of internal combustion engine, wherein, described in go Baking soda to have the described outer work of increase
The reinforcement of plug pin intensity.
The outer piston pin of above-mentioned a kind of internal combustion engine, wherein, the bottom of described outer piston pin is sphere, and
And the bottom of described outer piston pin has the hole passed for bearing pin, to be connected with external outer piston.
The outer piston pin of above-mentioned a kind of internal combustion engine, wherein, described inner carrier pin have a small end of connecting rod with
And the top being positioned at described small end of connecting rod, and the stifled inner carrier pin being connected by small end of connecting rod bolt.
Due to the fact that and have employed above-mentioned technology, the good effect being allowed to compared with prior art have is:
1, only one of which piston in one cylinder of traditional electromotor, piston constitutes combustion with cylinder cap, valve
Burn room, and OPOC engine structure is to be provided with inside and outside two pistons in a cylinder, passes through
Two piston composition combustor, meet OPOC engine structure requirement.
2, the both sides of outer piston pin are connected by two connecting rods, not only meet structure and arrange and function, with
Time make the stress of connecting rod become the half of conventional structure, first connecting rod deflection reduce, effectively promote
Electromotor；Secondly connecting rod material requires to reduce further, and the cost making electromotor is more competitive.
3, this version is applicable not only to conventional in-line internal combustion engine, is also applied for horizontal versions internal combustion
Machine, coordinates custom-designed respective pistons link assembly, obtains at horizontally-opposed cylinder opposed piston internal combustion engine
To preferably using.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the outer piston pin of a kind of internal combustion engine of the present invention；
Fig. 2 is the schematic diagram of the inner carrier pin of a kind of internal combustion engine of the present invention.
Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as the present invention's
Limit.
Fig. 1 is the schematic diagram of the outer piston pin of a kind of internal combustion engine of the present invention, shown in Figure 1.This
The outer piston pin of a kind of internal combustion engine of invention, includes an outer piston pin 1 and is positioned at outer piston pin 1 both sides
Plug 2, and one with outer piston pin 1 be mutually matched the inner carrier pin being arranged on external internal combustion engine.
The present invention the most also has a following embodiment:
In further embodiment of the present invention, continuing with shown in Figure 1.Being shaped as of outer piston pin 1
" T " font, outer piston pin 1 installs the both sides of plug 2 and is processed to form the bearing pin 21 of cylinder the most respectively,
Two bearing pins 21 have the effect increasing lubricant effect.Each bearing pin 21 is processed to form two planes 22,
Two planes 22 are for increasing the contact area of lubricating oil.And in plane 22, offer radial direction oil hole 23.
In further embodiment of the present invention, each bearing pin 21 is further opened with an axial oilhole 24, often
One plug 2 matches with each axial oilhole 24.Formed after plug 2 is installed and blocked axial oilhole 24
One shoe cream room carries out oil storage.
In further embodiment of the present invention, there is in the centre of bearing pin 21 Baking soda, radial direction oil hole 23
It is interconnected with removing Baking soda.Lubricating oil from external piston cooling nozzle is both to piston, and outer piston pin is entered
Row cooling, can be lubricated by oilhole again.
In further embodiment of the present invention, being also devised with a reinforcement in removing Baking soda, reinforcement is used
In increasing outer piston pin intensity.
