Abstract
The utility model discloses an oil circuit for lubricating and cooling the piston in right box of the motorcycle engine, including a right box and a piston. The right box is provided with an oil branch for lubricating and cooling the piston, the oil branch is communicated with the main oil circuit, one end of an oil pipe is communicated with the oil branch and the other end extends into the top of the inner wall of the piston. The utility model is added with an oil branch for lubricating and cooling the piston based on the original spraying lubrication, which directly leads the engine oil to be sprayed on the piston top through the oil pipe, thus achieving the aim of cooling the piston. The newly-added oil circuit can greatly improve the operational environment of the piston, reduce the heat load and wearing of the piston, increase the reliability and the service life of the piston.
Description
Technical field
The utility model relates to the lubricated and cooling oil circuit design of motorcycle engine, specifically refers to increase on the motorcycle engine right case oil circuit of lubricated and cooling piston.
Background technique
Good lubricated and cooling is that motorcycle engine is normally moved essential condition, and is all the more so for piston, because piston directly links to each other with the firing chamber, high temperature, high pressure that burning produces directly act on piston crown; Simultaneously, piston is to-and-fro motion in cylinder, also can produce very high temperature with cylinder inner wall friction, needs constantly cooling and lubricated, the reliability that could guarantee work with increase the service life.At present, the lubricating system of most of engine components is to be provided with the main oil gallery that communicates with oil pump on right case, the machine oil that oil pump pumps under the effect of pressure by main oil gallery and branch's oil circuit of communicating with main oil gallery, be sent to each component and sentence and reach effect lubricated and cooling, and the main machine oil that rotation drives by connecting rod of the lubricated and cooling of piston is splashed to piston base and reaches lubricated and cooling effect.Increase along with engine displacement, the heat load of piston also increases thereupon, running environment is more abominable, but splash lubrication is because the characteristics of self are difficult to arrival at some position, especially when piston runs to top dead center, the poor heat stability that causes piston thus, surface abrasion is accelerated, so the traditional splash lubrication and the type of cooling can not satisfy actual demand.
The model utility content
At the prior art above shortcomings, a kind of lubricated, cooling oil circuit that can improve piston lubrication and cooling effect greatly that the purpose of this utility model provides.
The technical solution of the utility model is achieved in that the motorcycle engine right case lubricates and the oil circuit of cooling piston, comprise right case and piston, on right case, be provided with main oil gallery that communicates with oil pump and the branch's oil circuit that communicates with main oil gallery, it is characterized in that: another oil circuit branch that has additional lubricated and cooling piston on the described right case, this oil circuit branch communicates with main oil gallery, oil pipe one end is communicated with oil circuit branch, and the other end stretches into the piston inner wall top.
Further, described oil pipe embeds in the oil circuit branch with it interference fit and locatees by the positioning step on the oil pipe.
The utility model is in the oil circuit branch (strengthening the pump oil mass of oil pump simultaneously) that increases lubricated and cooling piston on the basis of original splash lubrication on the motor right case, by oil pipe machine oil is drawn and directly to spray piston head, reach the purpose of cooling piston, this newly-increased oil circuit branch can improve the running environment of piston greatly, reduce piston heat load and wear extent, improve the reliability and the working life of pistons work.
Description of drawings
Fig. 1-the utility model structural representation;
Fig. 2-vitta structure schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, as can be seen, the oil circuit of the lubricated and cooling piston of the utility model motorcycle engine right case comprises right case 1 and piston 2 from the figure, be provided with main oil gallery that communicates with oil pump and the branch's oil circuit that communicates with main oil gallery on right case 1, this is the lubricating oil path of prior art.Improvement of the present utility model is to have additional another oil circuit branch (strengthening the pump oil mass of oil pump simultaneously) of lubricated and cooling piston on right case 1, this oil circuit branch communicates with main oil gallery equally, draws an oil pipe 3 piston head that comes out directly to spray by this oil circuit branch again.The structure of oil pipe 3 is seen Fig. 2, and the one end embeds in the oil circuit branch with it interference fit and by 4 location of the positioning step on the oil pipe, the other end stretches into the piston inner wall top.Newly-increased oil circuit branch will pay special attention to not make oil pipe that back and crank interference are installed.
The machine oil that the utility model comes out from oil pump directly sprays the piston inner wall top by oil pipe under the effect of oil pressure, take away piston region part heat by lubricant oil, thereby reach cooling piston, improve the purpose of piston running environment, be mainly used in large-duty engine.
