as described in the background art, in the prior art, there is a problem that impurities existing in an oil passage of an engine body easily damage lubrication characteristics between the components, and in order to solve the technical problem as described above, the invention provides a main oil passage for removing impurities, a lubrication system and an engine.
Example 1
In an exemplary embodiment of the present invention, referring to fig. 1, a main oil gallery for removing impurities includes a main oil gallery 1, wherein the main oil gallery 1 is provided with a preformed hole 2 at a side close to a gear chamber, the preformed hole 2 is located above an oil pan, and when the main oil gallery 1 operates, part of oil carries impurities in the main oil gallery 1 to flow to the preformed hole 2, and flows to the oil pan through the preformed hole 2.
It should be explained that the main oil duct 1 is a main oil duct pipeline of the lubrication system, the main oil duct 1 is provided with a main oil duct inlet 3, a pipeline is arranged at the main oil duct inlet 3, the pipeline is connected with the main oil duct to form a main oil duct inlet 3, the main oil duct inlet 3 is connected with an oil injection pump to enable lubricating oil to enter the main oil duct through the main oil duct inlet 3, the main oil duct 1 is positioned above an oil pan, an oil filter is arranged between the oil injection pump and the oil pan, a central axis of the pipeline at the main oil duct inlet 3 is perpendicular to a central axis of the main oil duct, and the main oil duct inlet 3 is positioned at the side part of the main oil duct 1; it will also be appreciated that the conduit at the main oil gallery inlet 3 may be disposed in the same plane as the main oil gallery 1 or that the conduit at the main oil gallery inlet 3 may intersect the main oil gallery 1.
Considering the open position of the inlet of the main oil gallery, the preformed hole 2 is positioned at the end of the main oil gallery 1 close to the gear chamber, so that along with the flow of the lubricating oil, impurities can be smoothly discharged through the main oil gallery, and cannot remain in the main oil gallery 1 to block the main oil gallery, but can be directly discharged from the preformed hole at the end of the main oil gallery along with the flow of the lubricating oil.
Of course, in other examples, the preformed hole 2 may be provided on the inner side of the main oil gallery 1 near the end of the gear chamber, at the lower part of the side of the main oil gallery, and the preformed hole 2 is located 0-5mm near the end of the gear with the main oil gallery 1, so that the preformed hole is provided at a position especially on the main oil gallery 1 near the end of the gear, in consideration of a certain diameter, so that impurities can flow out directly from the preformed hole downwards along with the lubricating oil, directly fall into the oil pan below, and will not remain in the main oil gallery 1.
In this embodiment, the preformed hole 2 is a tapered circular hole, and because the end of the main oil duct 1 has a set thickness, the smaller side of the preformed hole 2 is located outside the main oil duct 1, and the larger side of the preformed hole 2 is located inside the main oil duct 1, so that the flow velocity of the lubricating oil is increased when passing by, and impurities are convenient to flow out from the preformed hole along with the lubricating oil rapidly.
Of course, in other examples, it is contemplated that the contaminants are generally nearly circular, or that the maximum length does not exceed the diameter of the preformed hole, so the preformed hole 2 may be other shapes, as long as it is a circular hole that does not trap contaminants in the lubricating oil.
To ensure smooth discharge of the impurities, it will be appreciated that the diameter of the preformed hole 2 is greater than the outer diameter of the impurities in the main oil gallery.
In some examples, the preformed holes have a diameter of 0.6mm to 2.4mm.
According to the size of impurity, usually the impurity is less than 1mm, all be the granule to avoid influencing lubricating system's pressure and flow, moreover because the setting position of preformed hole is the settlement distance with the main oil duct entry between, the diameter of preformed hole is 1mm-2mm, most preferably 1mm, because preformed hole 2 if too big, can influence the pressure and the flow of main oil duct internal lubricating oil, and pass test verification, specific verification data see table 1 shows that the bigger preformed hole diameter, the bigger the oil drain volume, the pressure of main oil duct also is lower, consequently do not guarantee main oil duct internal pressure, preformed hole 1mm-2mm can guarantee the smooth and easy flow of lubricating oil.

Referring to fig. 1, a main oil duct 1 is communicated with a plurality of inclined oil ducts 4, in some examples, a plurality of inclined oil ducts 4 are arranged together, a set distance is arranged between two adjacent inclined oil ducts 4, the two adjacent inclined oil ducts 4 are parallel to each other, a preset hole is arranged with the interval distance between the inclined oil ducts 4, the inclined oil ducts 4 are used for guiding lubricating oil to a bearing bush 5, and of course, the main oil duct 1 is also provided with other lubricating oil ducts so as to convey the lubricating oil to other mechanisms such as a crankshaft for lubrication, and a set distance is also arranged between the preset hole 2 and the nearest inclined oil duct.
It should be explained that the inclined oil passage 4 is located inside the main oil passage 1 and is disposed obliquely upward, the inclined oil passage is located inside the main oil passage with respect to the main oil passage inlet 3, and the main oil passage inlet 3 is located outside the main oil passage.
According to the main oil duct 1 provided by the invention, impurities mixed in the main oil duct flow along with the flowing of lubricating oil in the main oil duct through the arrangement of the reserved holes of the main oil duct, and then flow out of the reserved holes to the oil pan, so that the lubricating oil is effectively filtered through the oil filter in the circulation process, the impurities in the oil duct of an engine are integrally and effectively removed, and the faults such as bearing bush abrasion caused by unclean cleanliness are reduced.
Example two
The embodiment provides an engine lubrication system, including a main oil gallery for removing impurities as described in the first embodiment.
It will be appreciated that two main oil ducts 1 are provided, two main oil duct inlets 3 are provided in the main oil duct 1 respectively, the two main oil ducts are parallel to each other, the main oil duct 1 is located above the oil pan in the engine body, the preformed hole 2 is provided on one side of the main oil duct 1 near the gear chamber, mainly in consideration of the arrangement position of the main oil duct inlets 3 and the flowing direction of the lubricating oil, the distance between the main oil duct inlets 3 and the preformed hole 2 is set, because the lubricating oil flows along two sides of the main oil duct inlets 3 after entering from the main oil duct inlets 3, because the length of one side of the main oil duct inlets 3 near the end of the gear chamber is longer, the flowing speed of the lubricating oil on this side is faster, the impurities also mainly flow to this side, and therefore, the distance between the main oil duct inlets 3 and the preformed hole 2 is greater than the distance between the main oil duct inlets 3 and the other end of the main oil duct 1, so that the impurities in the main oil duct 1 are discharged as much as possible, but do not enter the inclined oil duct 4 communicated with the main oil duct 1.
It should be explained that the distances between the reserved holes of the two main oil channels and the nearest oblique oil channels are different.
In addition, the two main oil channels are separated by a set distance, and the pipelines at the main oil channel inlets 3 of the two main oil channels 1 are reversely arranged and face in opposite directions; in some examples, the central axes of the pipes at the two main oil gallery inlets 3 lie in the same longitudinal plane; of course, in some examples, the central axes of the pipes at the two main oil gallery inlets 3 may not lie in the same longitudinal plane.
