Abstract
The utility model relates to a kind of motorcycle engine radiating structure, comprise the right lid, right case, right cover pad, oil cooler, the right lid is installed on the right lid junction plane of right case, and right cover pad is installed between the right lid and right case, the right lid and right case junction plane main oil gallery.After motorcycle engine installs oil cooler, after machine oil is covered by the right and the oil drainage hole of right case junction plane main oil gallery enters oil cooler cooling, entered the oil inlet hole of the right lid and right case junction plane main oil gallery again by oil cooler, finally enter piston cavity top by right case nozzle opening.Oil temperature through oil cooler cooling significantly reduces 10-15 DEG C, effectively improves machine oil Yin Wendu too high and make the phenomenon of Cooling and Lubricator deleterious, thus effectively improves the Cooling and Lubricator effect of piston.
Description
Technical field
The utility model relates to a kind of motorcycle engine radiating structure.
Background technique
At present, the piston of motorcycle engines all on market is all direct to be connected with firing chamber, when motor is when running up, piston not only will bear chamber fuel and to burn the high temperature, the high pressure that produce, also will bear piston and cylinder inner wall simultaneously and to rub the high temperature produced.In order to the High Temperature High Pressure of bearing when reducing piston continuous firing, ensure the working stability of piston, extend its working life simultaneously, continuous Cooling and Lubricator must be carried out to piston.For this reason, have employed a series of technological scheme in industry and solve this difficult problem.In early days, the lubrication and cooling of piston mainly makes machine oil enter into piston cavity in the mode of splashing by the crankshaft & connecting rotated, and has part machine oil to penetrate into cylinder inner wall by the oilhole of piston ring land simultaneously, thus carries out lubrication and cooling to it.Afterwards, along with the discharge capacity of motorcycle engine increases, the heat load of piston also increased, and the mode of the lubrication and cooling before utilization can not practical requirement.Therefore, those skilled in the art devise again the new oil circuit of a lube pistons inner cavity top, as in utility model patent ZL200920055410.0 the new oil circuit that provides.Although above-mentioned patent solves the under-supply problem of piston position lubricant oil well, but along with increasing progressively of engine operating duration, piston temperature and oil temperature synchronously rise, machine oil weakens the cooling action that piston plays thereupon, and when oil temperature is increased beyond its flash-point (about 150 DEG C), machine oil stickiness declines, thus its lubrication effect is deteriorated.Now, easily there is with the mutual friction of cylinder inner wall phase burnout phenomenon of dry grinding in piston.
Summary of the invention
The purpose of this utility model is to provide a kind of motorcycle engine radiating structure that effectively can reduce piston temperature and oil temperature.
technological scheme
The purpose of this utility model is achieved in that a kind of motorcycle engine radiating structure, comprise the right lid, right case, right cover pad, oil cooler, the right lid is installed on the right lid junction plane of right case, right cover pad is installed between the right lid and right case, the right lid and right case junction plane main oil gallery, its special way is: oil cooler hangs upper end, hole before being installed on right case, oil cooler oil inlet pipe covers with the right and the oil drainage hole of right case junction plane main oil gallery is connected, and oil cooler oil exit pipe covers with the right and the oil inlet hole of right case junction plane main oil gallery is connected.
Described motorcycle engine radiating structure, its special way is: the oil duct between the oil inlet hole of right case junction plane main oil gallery and oil drainage hole is provided with muscle, right cover pad is provided with oilhole at right cover oil inlet hole and right case upper cylinder half oil circuit place, makes the oil duct between the right lid and the entering of right case junction plane main oil gallery, oil drainage hole be sealing state.
Described motorcycle engine radiating structure, its special way is: oil cooler material is the material that thermal conductivity is high, and its transport pipe used is copper pipe, and its fin material is aluminium flake.
beneficial effect
Technological scheme described in the utility model, by being provided with muscle at right case, right cover pad is provided with two oilholes, while not changing original lubrication effect, right case and right cover working connection are separated twice oil circuit, an oil circuit enters the right lid oil circuit and upper cylinder half oil circuit by former route; Another oil circuit is then covered by the right and the oil drainage hole of right case junction plane main oil gallery enters after oil cooler cools, then enters the right by oil cooler and cover and the oil inlet hole of right case junction plane main oil gallery, finally directly sprays piston head by right case nozzle opening.Oil temperature through oil cooler cooling significantly reduces 10-15 DEG C, effectively improves machine oil Yin Wendu too high and make the phenomenon of Cooling and Lubricator deleterious, thus effectively improves the Cooling and Lubricator effect of piston.
Accompanying drawing explanation
Fig. 1 is a kind of motorcycle engine radiating structure schematic diagram described in the utility model.
Fig. 2 is lid working connection plan view on the right of motorcycle engine radiating structure described in the utility model.
Fig. 3 is motorcycle engine radiating structure right cover pad plan view described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, concrete structure of the present utility model is further described.
With reference to Fig. 1,2,3, motorcycle engine radiating structure, comprise the right lid 1, right case 2, oil cooler 3, right cover pad 4, the right lid 1 is installed on the right lid junction plane 21 of right case 2, right cover pad 4 is installed between the right lid 1 and right case 2, the right lid 1 and right case 2 junction plane main oil gallery 22.Oil cooler 3 hangs upper end, hole before being installed on right case 2, and oil cooler 3 oil inlet pipe 31 covers with the right and the oil drainage hole 23 of right case junction plane main oil gallery 22 is connected, and oil cooler 3 oil exit pipe 32 covers with the right and the oil inlet hole 24 of right case junction plane main oil gallery 22 is connected.
Oil duct between the oil inlet hole 24 of right case 2 junction plane main oil gallery 22 and oil drainage hole 23 is provided with muscle 25, right cover pad 4 is provided with oilhole 41 at right cover 1 oil inlet hole 11 and right case 2 upper cylinder half oil circuit place, makes the oil duct between the right lid 1 and the entering of right case 2 junction plane main oil gallery 22, oil drainage hole be sealing state.
Oil cooler 3 material is the material that thermal conductivity is high, and its oil inlet pipe 31 used and oil exit pipe 32 are copper pipe, and its radiating fin 33 material is aluminium flake.
By being provided with muscle 25 at right case 2, right cover pad 4 is provided with two oilholes 41, while not changing original lubrication effect, right case 2 and right cover 1 working connection 22 separated twice oil circuit, and an oil circuit enters the right lid oil circuit and upper cylinder half oil circuit by former route; Another oil circuit then by the right cover 1 and the oil drainage hole 23 of right case 2 junction plane 21 main oil gallery 22 enter after oil cooler 3 cools, entered the oil inlet hole 24 of the right lid 1 and right case 2 junction plane 21 main oil gallery 22 again by oil cooler 3, finally directly sprayed to piston cavity top by right case 2 nozzle opening 26.Oil temperature through oil cooler cooling significantly reduces 10-15 DEG C, effectively improves machine oil Yin Wendu too high and make the phenomenon of Cooling and Lubricator deleterious, thus effectively improves the Cooling and Lubricator effect of piston.
