Description
Technical field
The utility model relates to a kind of piston structure of effectively lubricating ladder connecting rod small end.
Background technique
Motor is as the heart component of automobile, and the parts such as piston rod, as the power-conversion of motor and output mechanism, carry major function heat energy (oil inflame) being converted into mechanical work.Diesel engine is that the chemical energy of diesel combustion is converted to mechanical energy, when motor runs, the working environment of piston rod is quite severe, bears the impact force that high temperature, high pressure and high-speed motion produce, while guarantee mechanical strength, the cooling and lubricating of its parts is most important.Internal combustion (IC) engine link rod microcephaly mainly relies on splash lubrication traditionally, and along with engine strength degree improves constantly, the mechanical load of connecting rod small end significantly improves, and its lubricating condition must corresponding improvement.Ladder connecting rod is generally applied on the strengthening internal-combustion engine of higher detonation pressure and power per liter, therefore ensures that the lubricating condition that ladder connecting rod small end is good is particularly important.
Along with the raising of motor detonation pressure pressure and power per liter, the mechanical load of connecting rod significantly improves, and wedge shape connecting rod and ladder connecting rod are widely used on high-speed high-load diesel engine, and microcephaly only relies on splash lubrication to be difficult to meet reliability and life requirement.
For wedge shape connecting rod small end, the lubricant oil flowed out from oil duct in piston can be utilized to lubricate connecting rod small end.Method normally bores two oilholes at connecting rod small end and piston cavity left and right sides antimere, the lubricant oil in oil duct in piston is flowed out from piston oilhole, enters connecting rod oilhole, thus reach the object of lubrication connecting rod small end.And ladder connecting rod is little due to microcephaly's area, oilhole cannot be bored by geometric space restriction microcephaly, even if piston keeps the oilhole of both sides, can not more effective lubrication connecting rod small end.
Please refer to the conventional piston structure shown in Fig. 3 to Fig. 4, it comprises: piston only 11, oil duct in piston 21, piston cavity 41, filler opening 71 and two oil outlets 31.Oil duct in piston 21 is arranged on piston only 11.Piston cavity 41 is arranged in piston only 11.Filler opening 71 is arranged in piston only 11.Two oil outlets 31 run through oil duct in piston 21 and are arranged on piston cross central line 61 with piston cavity 41, two oil outlets 31, and two oil outlets 31 are arranged in the both sides of the vertical center line 51 of piston, can not effectively lubricating ladder connecting rod small end.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
