Description
Technical field
The utility model auto parts and components field, especially a kind of novel durable piston that is applicable to automobile air compressor.
Background technique
Piston is one of worst key components and parts of operating conditions in automobile air compressor, directly contacts with high-temperature gas, and more than delivery temperature can reach 350 degree, and radiating condition is very poor, so temperature is very high when pistons work; In addition, piston ring is jaggy after installing, and jaggedly just has gas leakage, it is large that the size of air leakage becomes gradually with the wearing and tearing of cylinder barrel, when cylinder barrel wearing and tearing acquire a certain degree, the seal action of piston ring will decline, and the thermal efficiency reduces, and these all can have a strong impact on the working life of piston.
Model utility content
The utility model aims to provide a kind of novel durable piston that is applicable to automobile air compressor.
For realizing this technical purpose, scheme of the present utility model is: a kind of novel durable piston that is applicable to automobile air compressor, comprises piston body, piston head, pin-and-hole, compression ring, oil ring, scrapes piece, skirt section, oil inlet hole, pin-and-hole seat and cavity; Described piston body inside is hollow, described piston head is located at piston body upper end, on described piston body, be provided with pin-and-hole, it is that two, oil ring are one that described piston head outer wall is provided with compression ring and oil ring and compression ring, described compression ring is arranged on oil ring top, on described oil ring outer wall, be provided with and scrape piece, be provided with pin-and-hole seat and pin-and-hole seat is provided with oil inlet hole in described piston body, both sides, piston head below are fixed in described skirt section.
Preferably, in described piston head, be provided with cavity.
Preferably, between described compression ring and between compression ring and oil ring, form compression, described oil ring and piston body form oil ring groove, and the twice that one compression width of the top is other annular groove, is dicyclo groove.
Preferably, between described skirt section and pin-and-hole seat, be provided with the gap of 4.5～5.0mm.
Compared with prior art, the beneficial effects of the utility model are: this novel durable piston structure that is applicable to automobile air compressor is simple, easy to use, can conveniently safeguard piston, when the design of scraping piece can make piston movable in cylinder, cylinder inner wall oil reservoir is scraped evenly; The setting of cavity has alleviated overall weight, thereby has reduced inertial force, has reduced power consumpiton, can reduce air-following oil drain quantity; The thermal distortion that the arranging of gap can be blocked pin-and-hole seat is conducted to skirt section, and the setting of distance is more reasonable, has still ensured enough strength and stiffness playing the heat conducting while of blocking-up; The setting of dicyclo groove, greatly reduces air leakage, extends the working life of piston.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side sectional view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, in the utility model embodiment, a kind of novel durable piston that is applicable to automobile air compressor, comprises piston body 1, piston head 2, pin-and-hole 3, compression ring 4, oil ring 5, scrapes piece 8, skirt section 9, oil inlet hole 11, pin-and-hole seat 13 and cavity 12; Described piston body 1 inside is hollow, described piston head 2 is located at piston body 1 upper end and piston head 2 inside are provided with cavity 12, on described piston body 1, be provided with pin-and-hole 3, it is that two, oil ring 5 are one that described piston head 2 outer walls are provided with compression ring 4 and oil ring 5 and compression ring 4, described compression ring 4 is arranged on oil ring 5 tops, on described oil ring 5 outer walls, be provided with and scrape piece 8, in described piston body 1, be provided with pin-and-hole seat 13 and pin-and-hole seat 13 is provided with oil inlet hole 11, piston head 2 both sides, below are fixed in described skirt section 9, are provided with the gap of 4.5～5.0mm between described skirt section 9 and pin-and-hole seat 13.
Preferably, between described compression ring 4 and between compression ring 4 and oil ring 5, form compression 6, described oil ring 5 forms oil ring groove 7 with piston body 1, and the twice that one compression, 6 width of the top are other annular groove, is dicyclo groove.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any reference character in claim should be considered as limiting related claim.
