Abstract
The utility model relates to a kind of piston for motorcycle engine cooling mechanism, and comprise left box body, right case, oil pump combination and oil nozzle, described left box body and right case are fixed by mould assembling bolt; Described left box body and right case arrange oil nozzle bore, drive pin mounting hole is set on left box body simultaneously, be inserted in described oil nozzle bore by the seat stand at oil nozzle two ends, oil nozzle left end coordinates with drive pin, locates oil nozzle travel direction with drive pin; Described oil nozzle bore is communicated with oil circuit, and the assemblage gap that two ends, oil nozzle left and right realize casing and oil nozzle respectively by O type rubber seal seals.This model utility structure is unique, and tailored appearance, reasonably arranges cooling mechanism, effectively make use of the layout in space, ensure that strict oil spout angle and injection pressure, engine piston is effectively cooled, improves power, decrease oil consumption.
Description
Technical field
The utility model relates to piston for motorcycle engine cooling technology field, particularly a kind of novel piston for motorcycle engine cooling mechanism.
Background technique
At present, the application of piston cooling technology on motorcycle is less.The piston load of motorcycle engine is large, temperature is high, cooling effect is poor.Piston piston distortion just may be caused even to occur the danger such as cylinder of rising if can not get good cooling effect.If take the measure in the gap increased between piston and cylinder body, in piston reciprocating runs, just may cause abnormal sound and piston excursion wearing and tearing etc., the normal operation of motor time serious, can be affected.Within the engine, the layout of oil duct position, the flow of oil-feed and input pressure etc. have very large impact to cooling effect.In addition, the structure relative compact of motorcycle engine, small volume, the useful space are relatively less, and therefore the layout of cooling system is just comparatively difficult.Now, for motor internal cooling system be all leave separately in casing space arrange, as patent CN201320352629.3 discloses the motorcycle engine of band oil nozzle cooling unit, the oil nozzle of this model utility is positioned at crankcase intracavity and below described piston.The space taken is comparatively large, makes the piston of motorcycle engine can not get good cooling.
Model utility content
For overcoming problems of the prior art, the utility model provides a kind of piston for motorcycle engine cooling mechanism.
The technical scheme in the invention for solving the technical problem is: this kind of piston for motorcycle engine cooling mechanism, and comprise left box body, right case, oil pump combination and oil nozzle, it is characterized in that, described left box body and right case are fixed by mould assembling bolt; Described left box body and right case arrange oil nozzle bore, described left box body arranges drive pin mounting hole, be inserted in described oil nozzle bore by the seat stand at oil nozzle two ends, oil nozzle left end coordinates with drive pin, locates oil nozzle travel direction with drive pin; Described oil nozzle bore is communicated with oil circuit.
This model utility by arranging oil nozzle bore respectively on left box body and right case, oil nozzle is fixed between left box body and right case, achieved by drive pin and the direction of oil nozzle is located, oil nozzle jet is made to aim at piston oil spout, good cooling results, cooling effectiveness is high, effectively make use of space simultaneously;
Further, the assemblage gap that two ends, oil nozzle left and right realize casing and oil nozzle respectively by O type rubber seal seals.
Achieved the sealing of casing and oil nozzle assemblage gap by O type rubber seal, ensure that injection pressure to a certain extent.
To sum up, the beneficial effect of technique scheme of the present utility model is as follows: utilize limited space to achieve the reasonable Arrangement of cooling mechanism, by oil nozzle bore, oil nozzle is arranged on left box body and the position be connected in the middle of right case, has greatly saved space.By the accurate location of drive pin to oil spout, ensure that the oil spout angle that oil nozzle is strict and injection pressure, good cooling results, cooling effectiveness is high, make motor can carry out rationally effective piston cooling under various operating mode, overcoming piston answers thermal distortion to rise the defects such as cylinder, improves power, decreases oil consumption.

Embodiment
Be described in detail to characteristic sum principle of the present utility model below in conjunction with accompanying drawing, illustrated embodiment, only for explaining the utility model, not limits protection domain of the present utility model with this.
As shown in Figure 1 and Figure 2, this model utility comprises: left box body 4, right case 5, oil pump combination 6 and oil nozzle, and shown left box body 4 is fixed by mould assembling bolt 9 with right case 5, to realize oil nozzle combination 1 to be arranged between left box body and right case.Described left box body and right case arrange oil nozzle bore, drive pin 3 mounting hole is set on described left box body simultaneously, the seat stand of oil nozzle is inserted in described oil nozzle bore, adjust the angle of oil nozzle, make the jet of oil nozzle just to piston, then oil nozzle left end is coordinated with drive pin, realized the location of oil nozzle travel direction by drive pin, the oil from oil pump 6 is just ejected on piston by oil nozzle.Described oil nozzle is made up of injector body 7 and nozzle pipe 8, and described nozzle pipe 8 is welded on oil nozzle 7.
Oil nozzle bore is communicated with oil circuit, ensures that the oil from oil pump 6 arrives oil nozzle smoothly.In oil nozzle, the pressure of oil needs to be guaranteed in addition, and oil spurts just can be made on piston.Therefore, by laying at two ends, oil nozzle left and right the sealing that O type rubber seal 2 realizes casing and oil nozzle assemblage gap respectively, ensure that injection pressure to a certain extent.In addition, in order to ensure injection pressure, the volume of oil pump suitably can be strengthened.
This model utility makes motor can carry out rationally effective piston cooling under various operating mode, improves power, decreases oil consumption.
Above-described embodiment is only the description carried out preferred implementation of the present utility model; not scope of the present invention is limited; under the prerequisite not departing from the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in the determined protection domain of the utility model claims.
