Abstract
The utility model discloses a motorcycle engine piston structure, which comprises an upper cylindrical piston head part and a lower cylindrical piston skirt part as well as a piston pin hole which is arranged on the middle part of the piston skirt part, and the motorcycle engine piston structure is characterized in that the piston head part is provided with a ceramic layer in a galvanization way, and the piston skirt part is provided with a wear-resisting layer in a galvanization way. The motorcycle engine piston structure has advantage of longer service life.
Description
Technical field
The utility model relates to a kind of motorcycle engine, especially a kind of motorcycle engine piston structure.
Background technique
The motorcycle engine piston structure is mainly by superposed piston crown, and the piston skirt that is positioned at the bottom constitutes with the piston pin hole that is positioned at the intermediate portion, piston skirt.Piston places in the cylinder block, links to each other with the connecting rod of lower end through wrist pin, under the pressure of explosion effect of burning indoor fuel gas, moves up and down along cylinder, gives bent axle through connecting rod with transmission of power.Piston is wanted high temperature high voltage resistant, and need be wear-resisting, therefore need possess certain intensity, but weight again can not be too high, otherwise the reciprocal inertia force of piston is too big, can cause the vibration of motor excessive, and the life-span of car load is all influenced with the rider travelling comfort.
Existing motorcycle engine piston, in its using process, piston crown bears the firing pressure of firing chamber for a long time, and is damaged easily; Simultaneously, the long-term gentle cylinder piston passage in piston skirt rubs mutually, and also easy abrasion causes piston shorter working life.
The model utility content
To the deficiency of above-mentioned existing technology, the utility model technical problem to be solved is how a kind of motorcycle engine piston structure of longer service life is provided.
In order to solve the problems of the technologies described above, adopted following technological scheme in the utility model:
A kind of motorcycle engine piston structure; Comprise cylindrical piston head that is positioned at the top and the circle tube piston skirt section that is positioned at the below; And the piston pin hole that is positioned at the centre, piston skirt; Its characteristics are that said piston crown adopts to electroplate and is provided with ceramic layer, and said piston skirt is electroplated and is provided with wearing layer.
In the utility model, bearing the piston crown of combustion gas high pressure for a long time, adopting can increase its intensity after electroplating one deck ceramic layer, improves its working life.In addition, after one deck wearing layer is electroplated in the piston skirt, also can improve the skirt section rub proofness, improve working life.Wherein said plating is to belong to the existing processes technology, and not this tired stating, said wearing layer generally is to adopt existing wear resistance alloy material electrodeposited coating preferably.
In sum, the utlity model has the advantage of longer service life.
Description of drawings
Fig. 1 is the main sectional view of the motorcycle engine piston structure of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
During practical implementation; As shown in Figure 1; A kind of motorcycle engine piston structure comprises cylindrical piston head 1 that is positioned at the top and the circle tube piston skirt section 3 that is positioned at the below, and is positioned at the piston pin hole 2 in the middle of the piston skirt; Said piston crown 1 adopts to electroplate and is provided with ceramic layer 4, and said piston skirt 3 is electroplated and is provided with wearing layer 5.
