Abstract

The utility model relates to a novel piston ring for motorcycles and vehicles, which is mainly suitable for the sealing of cylinder pistons of vehicle or motorcycle engines and is also suitable for the sealing of cylinder pistons of engines of other motor vehicles, internal combustion engine groups, etc. The novel piston ring is composed of two sealing rings, wherein, the sealing rings are in the shape of an opened ring, and the opening positions of the sealing rings are mutually sticking type bevel face opened faces. The utility model has the technical characteristics that no noise exists, the wear resistance is raised, the air pollution can be reduced, fuel oil is saved by about 30%, the wear is reduced by about 50%, the horse power is increased by 10-50%, the service life is extended by more then three times, an engine cylinder piston ring which is free from detachment forever is obtained, etc.

Description

Motor cycle, piston of automobile ring

The utility model relates to a kind of motor cycle, piston of automobile ring, mainly is applicable to the sealing of automobile, motor cycle engine cylinder piston.Also applicable to the sealing of engine cylinder pistons such as other power actuated vehicle, internal combustion unit.

The automobile that tradition is used, the cylinder piston seal ring of motor cycle engine are open circuited annular seal ring.New seal ring in use, gap does not have the slit basically, sealing property is relatively good, but use after a period of time, because the wearing and tearing of cylinder inner wall, increasing seam appears in the gap of seal ring, cause the sealing property variation, and produce phenomenons such as noise, oil consumption, difficult startup.

The purpose of this utility model is a kind of motor cycle of design, piston of automobile ring, and main employing is designed to the inclined-plane cleaved facet at the gap of seal ring, reaches the purpose that remains excellent sealing performance.

Motor cycle, piston of automobile ring generally are made up of two seal rings, seal ring is open circuited ring-type, is mutual subsides formula inclined-plane cleaved facet at the gap of seal ring, makes the existing elastic seal effect of seal ring, open circuited seam can be do not produced again, excellent sealing performance can be remained.The ring body outside at second stage seal ring is the slightly-inclined side, and forming an angle of the flank is acute angle, and acute angle is positioned at the below during use, is mainly used in heat radiation, reduces wear, improves resistance to abrasion, increases lubricating effect.

Motor cycle, piston of automobile ring that the utility model is designed, main employing is designed to paste mutually formula inclined-plane cleaved facet at the cleaved facet of seal ring, make the existing elastic seal effect of seal ring, can remain excellent sealing performance again, can reach following technical characterictic: noiselessness, improve resistance to abrasion, can reduce atmospheric contamination, fuel-economizing about 30%, about 50%, the 10-50% that soups of reducing wear, improve service life more than 3 times, obtain to exempt from forever to tear open engine cylinder piston ring etc.

Fig. 1 is the structural representation of motor cycle, piston of automobile ring primary seal ring

Fig. 2 is the birds-eye view of Fig. 1

Fig. 3 is the structural representation of motor cycle, piston of automobile ring second-level sealing ring

Fig. 4 is that cut-away view is amplified in the part of Fig. 3

Present embodiment is made up of two seal ring primary seal rings (1) and second-level sealing ring (2), and seal ring (1), (2) are mutual subsides formula inclined-plane cleaved facet (3), (4), is ring-type slightly-inclined side (5) in the ring body outside of second-level sealing ring (2).Forming an angle of the flank is acute angle (6), and another angle of the flank is the obtuse angle, uses when installing, and the acute angle of seal ring will be positioned at the below, plays knife-type oil stripping action.

Claims

1, motor cycle, piston of automobile ring generally are made up of two seal rings, and seal ring is open circuited ring-type, it is characterized in that the gap at seal ring is a mutual subsides formula inclined-plane cleaved facet.

2, motor cycle according to claim 1, piston of automobile ring is characterized in that being the slightly-inclined side in the ring body outside of second stage seal ring that forming an angle of the flank is acute angle.
