Abstract

The utility model relates to a wear-resistant piston and piston ring unit component used for automobiles and motorcycles. One of piston annular grooves is wide groove (2), and at least two piston rings (3) and (4) are arranged in the piston ring wide groove (2); the openings of the piston rings (3) and (4) in the piston ring wide groove are mutually spaced. The piston ring wide groove (2) is compactly combined with the piton rings (3) and (4) in the groove. The utility model has the advantages of proper design and simple structure, making use of a multi-layer spacing seal to effectively enhance leak tightness and wear resistance, prominent oil saving effect, enlarging horsepower, quicker start, reducing engine noise, and prolonging service life by more than 3 times. The utility model is a novel and practical wear-resistant piston and piston ring unit component used for automobiles and motorcycles.

Description

Automobile, motorcycle Wear-resitsting pistons and piston-ring packing

Technical field

The utility model relates to automobile, motorcycle Wear-resitsting pistons and the piston-ring packing of a kind of engine pack, particularly a kind of good sealing effect.

Background technique

Existing automobile, the power of motorcycle relies on motor to provide, motor then relies on the piston acting, cooperating between piston and the cylinder, by the piston ring packing on the piston, in every piston circular groove piston ring is housed all, because piston ring is different with the manufactured materials of piston, its expansion coefficient is also different, add the needs of installation, so every piston ring on the piston all is an opening, one be disconnect shape piston ring in use for some time because the wearing and tearing of cylinder inner wall and the effect of expanding with heat and contract with cold, increasing seam can appear in the opening of piston ring, thereby reduce its sealing, cause scurrying on the lubricant oil, burn oil occurs, noise is big, oil consumption is big, hard-to-start, block problems such as cylinder, influence the working life of the power and the motor of vehicle.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved automobile, motorcycle Wear-resitsting pistons and piston-ring packing is provided, improve its structure, improve sealing and wear resistance, reduce noise, oil-saving effect is remarkable, increase horsepower, starting is fast, prolongs motor working life more than three times.

The purpose of this utility model can realize by following technical measures: this assembly has piston and piston ring, piston is provided with piston ring groove, having a piston ring groove at least is sipes, at least be equiped with two piston rings in the piston ring sipes, gap-clearance of piston rings in the piston ring sipes is staggered mutually, not in same angle, the groove width of piston ring sipes is corresponding with the thickness summation of each piston ring of installation in the groove, and the piston ring in piston ring sipes and the groove closely cooperates.

During use, when increasing seam can appear in the opening of piston ring, the gap-clearance of piston rings in the annular piston sipes that coexists was staggered mutually, has sealed the other side's opening mutually, has guaranteed its sealability and wear-resisting property.

Of the present utility model reasonable in design, simple in structure, utilize multilayer dislocation sealing, effectively improved sealing and wear-resisting property, oil-saving effect is remarkable, increases horsepower, starting is fast, reducing engine noise, increase the service life more than three times, is a kind of automobile, motorcycle Wear-resitsting pistons and piston-ring packing of Nover practical.

Description of drawings

Fig. 1 is a structural drawing of the present utility model.

Embodiment

With reference to Fig. 1, the piston of this assembly [1] is provided with three piston ring grooves, first layer piston ring groove [2] is a sipes, the width of piston ring sipes is two times of piston ring ring width, two piston rings [3], [4] are housed in the piston ring sipes, piston ring [3] in the piston ring sipes [2], the opening of [4] several angle that staggers mutually, piston ring [3], [4] closely cooperate with piston ring sipes [2], improve sealing and wear-resisting effect.The quantity that is installed in the piston ring of piston ring sipes can be decided as required, can be two, three, four etc., as long as the corresponding cooperation of width of piston ring sipes can be implemented; The piston ring sipes of piston also can be set according to actual needs, can establish a piston ring sipes, also can establish two piston ring sipes, even many piston ring sipes.

Claims

1, a kind of automobile, motorcycle Wear-resitsting pistons and piston-ring packing, piston [1], piston ring groove [2], piston ring [3], [4] are arranged, it is characterized in that piston ring groove has at least one to be sipes [2], at least be equiped with two piston rings [3], [4] in the piston ring sipes [2], piston ring [3], [4] opening in the piston ring sipes stagger mutually, the groove width of piston ring sipes [2] is corresponding with the thickness summation of the interior installation of groove each piston ring [3], [4], and piston ring sipes [2] closely cooperates with groove inner carrier ring [3], [4].
