Abstract
The utility model discloses a high-strength combustion engine piston which comprises a piston head portion, a piston ring groove, a piston skirt, a piston cavity and a piston pin hole, wherein the piston pin hole penetrates through the piston skirt, and is integrated with the piston. The main load bearing part of the piston is located on the pin hole, the forced area of the pint hole is larger, the reciprocating force pressure received by the pin hole is smaller under the same load, and namely the load bearing capability of the pin hole is stronger. The pin hole structure of the piston has larger forced area than a traditional pin hole, which greatly strengthens the load bearing capability of the piston, and facilitates the piston to have stronger strength and rigidity. The high-strength combustion engine piston is easy to process and cast, can satisfy the requirements of high-power high-strength combustion engines, and has long service life and high economic benefits.
Description
Technical field
The utility model relates to a kind of piston, particularly a kind of high strength internal combustion engine piston.
Background technique
Piston is the heart of diesel engine, in the using process of internal-combustion engine, piston bears reciprocal inertia force, and piston mainly carries the position all at the pin-and-hole position, traditional internal-combustion engine, see Figure of description 1, wherein b figure is the A-A sectional view of a figure, and as seen its piston pin hole position all is a suspension type, structure is that pin-and-hole is connected in one by gusset and piston only, so, finally carrying reciprocal load is to be born by four ribs, because the four ribs sectional area is little, the load of bearing is just very limited, along with the increase of piston carrying, suspension type pin-and-hole piston just can't satisfy the load requirement, thereby shortens the life-span of piston greatly.
The model utility content
The purpose of this utility model is to overcome the existing structural deficiency of internal combustion engine, and a kind of new high strength internal combustion engine is provided.
The technological scheme that realizes the utility model purpose is a kind of high strength internal combustion engine, has piston crown, piston ring groove, piston skirt and piston die cavity, is provided with piston pin hole in the described piston skirt.
Described piston pin hole runs through the piston skirt, with piston be an integral body.
The utility model adopts technique scheme, brought following beneficial effect: be provided with the piston pin hole that runs through the piston skirt in the piston skirt of the present utility model, change piston pin hole into the supporting type piston pin hole by original suspension type, directly piston pin hole is fixed in the piston, increase the loaded area of piston, promote the intensity of high piston, improve piston working life greatly, have very high economic benefit and use value.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the piston structure figure of prior art.
Fig. 2 is a kind of structural scheme of mechanism of the present utility model.
Fig. 3 is the right elevation of Fig. 2.
Embodiment
(embodiment 1)
See Fig. 2 and Fig. 3, a kind of high strength internal combustion engine of present embodiment has piston crown 1, piston ring groove 2, piston skirt 3, piston die cavity 4 and piston pin hole 5.
Piston pin hole 5 runs through piston skirt 3, with piston be an integral body.
Like this, piston head is positioned at the piston the topmost part, and piston pin hole is positioned at the piston middle part, and the piston skirt is positioned at lower part of piston, and three positions are connected in one, and being equivalent to piston pin hole and piston is an integral body.Piston mainly carries the position all at the pin-and-hole position, according to P=F/S, wherein P unit is a pressure, and F is a power, and S is an area, under the equal situation of F, S is big more, and P is more little, that is to say that under identical load, the lifting surface area of pin-and-hole is big more, the suffered reciprocating force pressure of pin-and-hole is more little so, that is to say that the bearing capacity of pin-and-hole is strong more.Pin-and-hole structure of the present utility model is bigger than traditional pin-and-hole lifting surface area, makes the bearing capacity of piston strengthen greatly, has higher intensity and rigidity.The utility model is easy to the processing casting, can satisfy high-power, high-intensity internal-combustion engine and use this internal combustion engine long service life, economic benefit height
Should be appreciated that specific embodiment described above only is used to explain the utility model, and be not used in qualification the utility model.Conspicuous variation of being extended out by spirit of the present utility model or change still are among the protection domain of the present utility model.
