Now the lubricating oil of piston main oil gallery is caused connecting rod, injected directly on piston lower surface by the oil duct of two on connecting rod.So not only processing is simple, and reduces costs low, eliminates the installation of piston cooling nozzle, reduces the risk that piston cooling nozzle lost efficacy.
Utility model content
The purpose of this utility model is to provide a kind of piston of automobile engine cooling oil duct arrangement, solve existing automobile engine to also exist, the cooling of piston needs by arranging piston cooling nozzle to realize, and piston cooling nozzle easily lost efficacy, and makes piston cannot arrive the problem of cooling object.
The technical solution of the utility model is: a kind of piston of automobile engine cooling oil duct arrangement, comprises bent axle, connecting rod, piston, bent axle is provided with a suite axle journal and one group of rod journal; Con-rod only comprises shaft, the small end of connecting rod for being connected with piston, big end for being connected with rod journal; Big end comprises connecting rod base, the connecting rod cap be connected with connecting rod base by bolt; Connecting rod on watt and connecting rod lower half bearing is provided with in big end; Connecting rod base is provided with one group of nozzle opening relative with piston base, the all sides of connecting rod on watt inwall are provided with the first rectangular channel, one group of oil outlet is provided with in first rectangular channel, oil outlet and nozzle opening align one by one, and all sides of connecting rod lower half bearing inwall are provided with the second rectangular channel connected with the first rectangular channel.
In order to ensure that on bent axle, oil circuit is reasonable in design, described maneton is provided with maneton oilhole, rod journal is provided with rod journal oilhole, is provided with the crankshaft oil passage for connecting both between maneton oilhole and rod journal.
Preferably, described maneton is provided with maneton on watt and lower watt of maneton, all sides of maneton lower watt of inwall are provided with the 3rd rectangular channel, are provided with the fuel feed hole just right with maneton oilhole in the 3rd rectangular channel.
In order to better cooling piston, described nozzle opening is positioned at shaft both sides and is respectively provided with one.
The utility model beneficial effect: the lubricating oil of main oil gallery is caused connecting rod, is injected directly on piston lower surface by the oil duct of two on connecting rod.So not only processing is simple, and reduces costs low, eliminates the installation of piston cooling nozzle, reduces the risk that piston cooling nozzle lost efficacy.The all sides of maneton lower watt of inwall are provided with the 3rd rectangular channel, the fuel feed hole just right with maneton oilhole is provided with in 3rd rectangular channel, can ensure like this, bent axle is in any one angle, can ensure that the oil that cylinder body main oil gallery enters in the 3rd rectangular channel can enter in maneton oilhole smoothly, oil-break phenomenon would not be occurred like this.Nozzle opening is positioned at shaft both sides and is respectively provided with one, the effect of nozzle opening be by big end inner ring around oil be sprayed onto piston lower surface, play the effect reducing piston heat load.No matter connecting rod forwards any one position to around bent axle, all can by oil spurts to piston base.
The utility model effectively can solve existing automobile engine and also exist, the cooling of piston needs by arranging piston cooling nozzle to realize, and piston cooling nozzle easily lost efficacy, and make piston cannot arrive the problem of cooling object, and structure is simple, easy realization, can be widely used in piston of automobile engine cooling field.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
