Abstract
The utility model discloses a motorcycle engine crank shaft box body with an internally-installed lubricating oil spraying hole structure. An oil passage ejecting mouth is arranged in the crank shaft box body. The motorcycle engine crank shaft box body enhances cylinder lubricating and cooling effect, prolongs service life of transmission pieces and the maintenance circle of a whole engine, and reduces maintenance cost of the whole engine.
Description
Technical field
The utility model relates to the motorcycle crankcase structure, is specifically related to a kind of motorcycle engine crankshaft box body of built-in lubricating oil spraying hole structure.
Background technique
Existing motorcycle engine, piston all directly link to each other with the firing chamber, and 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 the cylinder inner wall friction.In order to guarantee the reliability of pistons work, prolong simultaneously the working life of piston, just must carry out continuous Cooling and Lubricator to piston.The cooling of piston mainly relies on the heat transmission between itself and the cylinder wall outwards to dispel the heat, and piston lubricated is during only by crankshaft rotating, and the machine oil that has splashed is to piston lubrication.But because the oil level that splashes during crankshaft rotating is smaller, and the machine oil that has splashed can not drop on the piston inner wall skirt section usually exactly, so that machine oil is relatively poor to the cooling effect of piston, fails effectively lubricated and lower the temperature.Can not well lubricate and lower the temperature, so that the easily stuck and temperature rising of cylinder sleeve and piston, the working life of having reduced cylinder sleeve and piston.
Motorcycle engine as when the increasing compression ratio, cause the increase of wear extent and heating value, and the mode of existing cylinder lubrication and cooling can not practical requirement when improve improving the performance such as power, moment of torsion, power.
The model utility content
The utility model purpose is to strengthen cylinder lubrication and cooling effect, prolongs the life-span of driving component and the maintenance period of complete machine, reduces the maintenance cost of complete machine.For this reason, the utility model provides a kind of motorcycle engine crankshaft box body that can supply to cylinder block the built-in lubricating oil spraying hole structure of oil lubrication
For achieving the above object, the utility model by the following technical solutions:
The motorcycle engine crankshaft box body of built-in lubricating oil spraying hole structure, described crankcase are built-in with an oil duct jetburner.
Further, the cylinder connecting part of the contiguous crankcase body of described oil duct jetburner.
Further, described oil duct jetburner is corresponding with the slot to make way of cylinder block on being positioned at described crankcase body, and the lubricant oil that sprays through the oil duct jetburner passes the cylinder block slot to make way and is injected in the cylinder block.
The utlity model has following beneficial effect: (1) is by the bottom in engine piston, piston ring, cylinder block working position, the built-in pressurization oil duct jetburner of crankcase body passes the cylinder block slot to make way with lubricant oil and is directly injected to the component such as piston, piston ring, cylinder block and carries out high-efficiency lubricating and cooling; (2) the high-efficiency lubricating cooling reduces the surface friction drag of the component such as piston, piston ring, cylinder block, effectively reduces wear extent and prolongs the wear resistance that has improved motor its working life; (3) because the minimizing of the surface friction drag of the component such as piston ⑷, piston ring, cylinder block, the output power of motor is increased, play reduce fuel oil consumption, reduce discharge amount, reduced the Kohlenstoffgehalt that motorcycle is discharged in the process of moving, thereby realized the effect of energy-saving and emission-reduction.

Fig. 2 is cylinder block sectional view of the present utility model;
Fig. 3 is oil circuit schematic diagram of the present utility model;
Embodiment
For to structure of the present utility model, feature and effect thereof, can have and further understand and be familiar with, now lift a preferred embodiment, and be described with reference to the accompanying drawings as follows:
As Figure 1-3, the utility model passes through at engine piston 4, piston ring 5, crankcase body 2 built-in pressurization oil duct jetburners 1 of the bottom of cylinder block 3 working positions, described oil duct jetburner 1 is relative with the slot to make way of cylinder block, the lubricant oil 7 of oil duct jetburner 1 ejection passes cylinder block slot to make way 6 and is directly injected to piston 4, piston ring 5, cylinder block 3 component such as grade carry out high-efficiency lubricating and cooling, the high-efficiency lubricating cooling makes piston 4, piston ring 5, the surface friction drag of cylinder block 3 component such as grade reduces, and effectively reduces wear extent and prolongs the wear resistance that has improved motor its working life.
During engine running, under the effect of gear chamber self pressure, lubricant oil is lubricated cylinder sleeve and piston in nozzle opening spirt cylinder sleeve, has improved cooling-down effect.Reduced the wearing and tearing of cylinder sleeve and piston space, also greatly improve its working life.
The utility model oil injection structure is applied on the motorcycle engine of CG series, no matter reach the angle of energy-saving and emission-reduction purpose from improving function of the engine, or improve from the secondary development of CC1 motor good lubrication condition aspect analysis is provided, all than the existing advantage that obvious advantage and long term growth are arranged without the CG motor of this oil injection structure.
The above only is the preferred embodiment of the utility model; be not to limit practical range of the present utility model with this; all persons that is familiar with the technique; use principle of the present utility model and technical characteristics; various changes and the decoration done all should be covered by within the protection category that these claims define.
