Abstract
The utility model is a kind of motorcycle engine piston, and the horizontal oil groove and longitudinal oil groove opened up in the side wall of piston only, piston only is cylindrical piston, and is extended transversely through in piston and be provided with pin-and-hole, and bearing pin is socketed with the pin-and-hole；The starting point of longitudinal oil groove is at minimum horizontal oil groove together, and longitudinal open up downwards to the bottom face of piston only is stopped；The side wall of piston only is divided into arc section and pin-and-hole section, and two arc sections and pin-and-hole section symmetry arrangement, longitudinal oil groove are opened on arc section；Longitudinal oil groove described at least twice is offered in the side wall of piston only, piston ring is socketed with the horizontal oil groove.The utility model longitudinally increases multiple tracks oil groove in piston skirt, during piston longitudinally reciprocating motion, lubrication well cuts can effectively exclude downwards with the direction of motion, prevent because impurity clamping stagnation is on piston and cylinder contact surface, engine scuffing failure is caused, and improves engine reliability.
Description
Technical field
It the utility model is related to piston, and in particular to trunk-piston.
Background technology
Piston is parts reciprocating in Motor Engine Cylinder body.The basic structure of piston can be divided into top, head
Portion and skirt section.Top land is the major part for forming combustion chamber, and its shape is relevant with selected combustion-chamber shape.Gasoline engine
Use flat-head piston, its advantage is that endotherm area is small more.Usually there are various pits at the top of diesel engine piston, its specific shape
Shape, position and size must be all adapted with the mixed Daqu of diesel engine with the requirement burnt.Engine piston is engine
Core component, its performance directly affects the performance of engine, and therefore, the lubrication and carbon distribution of piston can directly influence engine
Performance.Pot type piston skirt section horizontal oil groove without oil groove or only, this structure can not solve engine because cleanliness issues are made
Into pull-cylinder phenomena.
Utility model content
In order to overcome the above-mentioned deficiency of prior art, the purpose of this utility model is that providing a kind of motorcycle engine lives
Plug, the motorcycle engine piston can provide longitudinal oil guide groove, be easy to the discharge of carbon distribution.
The utility model realizes that the technical scheme of above-mentioned purpose is：
A kind of motorcycle engine piston, the horizontal oil groove laterally opened up in the side wall of piston only and is longitudinally opened up vertical
To oil groove, piston only is cylindrical piston, and is extended transversely through in piston and be provided with pin-and-hole, and bearing pin is socketed with the pin-and-hole；It is described
The starting point of longitudinal oil groove is at minimum horizontal oil groove together, and longitudinal open up downwards to the bottom face of piston only is stopped；It is described
The side wall of piston only is divided into arc section and pin-and-hole section, two arc sections and pin-and-hole section symmetry arrangement, and longitudinal oil groove opens up
On the arc section；
Longitudinal oil groove described at least twice is offered in the side wall of piston only, piston is socketed with the horizontal oil groove
Ring.
The through hole through piston only is offered on the horizontal oil groove.
Longitudinal oil groove described in six is offered in the sidewall symmetry of the piston only.
Horizontal oil groove described in three is offered in the piston only, this three transverse directions oil groove parallel arrangement.
The utility model has following beneficial effect compared with prior art：
The utility model longitudinally increases multiple tracks oil groove in piston skirt, when piston upper and lower (longitudinal direction) moves back and forth, lubricating oil
Middle impurity can effectively exclude downwards with the direction of motion, prevent from, because impurity clamping stagnation is on piston and cylinder contact surface, causing engine
Scuffing of cylinder bore failure, and improve engine reliability.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is Fig. 1 A-A faces sectional view.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment：
Reference picture 1, a kind of motorcycle engine piston, in the horizontal oil groove 2 that the side wall of piston only 1 laterally opens up and indulge
To the longitudinal oil groove 4 opened up, piston only 1 is cylindrical piston, and is extended transversely through in piston and be provided with pin-and-hole, is socketed in the pin-and-hole
There is bearing pin 5；The starting point of longitudinal oil groove 4 is at minimum horizontal oil groove 2 together, and longitudinally opens up downwards to piston only 1
Bottom face stop；The side wall of the piston only 1 is divided into arc section and pin-and-hole section, two arc sections and pin-and-hole section symmetry arrangement,
Longitudinal oil groove 4 is opened on the arc section；
Such as Fig. 2, longitudinal oil groove 4 described at least twice is offered in the side wall of piston only 1, in horizontal 2 sets of the oil groove
It is connected to piston ring.The external diameter of piston ring is identical with the top outer diameter of piston only, and in high speed piston reciprocating motion, piston ring rises
To certain sealing effectiveness.
Longitudinal oil groove of the present utility model is arranged on the skirt section of piston only, and particular location is from minimum laterally oil together
Groove is until the bottom face of piston only, the groove structure penetrated downwards, described minimum to refer to using state shown in Fig. 1 as reference
Bottom together horizontal oil groove.Such as Fig. 2, the cross sectional shape in the skirt section of piston only, by the side wall in skirt section be divided into arc section and
Pin-and-hole section, two arc sections are as shown in Figure 2 in upper and lower ends, and pin-and-hole section is in left and right ends, due to pin-and-hole section structure in itself
Compared with piston only top cylindrical in contraction-like, itself have the function that necessarily prevent carbon distribution；And in arc section, its diameter
Identical with the diameter of top cylindrical, this section of side wall in skirt section can produce carbon distribution, and be not easy to drain, and therefore, longitudinal oil groove needs
It is opened on arc section.
The through hole 3 through piston only 1 is offered on the horizontal oil groove 2.
Preferably, such as Fig. 2, longitudinal oil groove 4 described in six is offered in the sidewall symmetry of the piston only 1.In work
The longitudinal direction oil groove of arrangement six of the sidewall symmetry of body is filled in, convenient for oil drainage row's carbon distribution, the performance of piston is improved, extends engine
Service life.
Such as Fig. 1, horizontal oil groove 2 described in three is offered in the piston only 1, this parallel arrangement of three transverse directions oil groove 2.
Embodiment not limited to this of the present utility model, according to the above of the present utility model, utilizes the general of this area
Logical technological know-how and customary means, under the premise of the above-mentioned basic fundamental thought of the utility model is not departed from, the utility model may be used also
To make the modification of other diversified forms, replacement or change, all fall within the utility model rights protection scope.
