The technical solutions in the exemplary embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Example 1
The engine oil strainer is a part of an engine lubricating system and mainly used as a transmission pipeline for an engine oil pump to suck oil from an oil sump, and the engine oil strainer is provided with a filter screen and can primarily filter the engine oil.
The oil strainer in the prior art is shown in fig. 1, and comprises an oil suction pipe 3, wherein a strainer cover and a strainer are arranged at one end of the oil suction pipe 3, the end is immersed in oil in an oil pan, and the right end is arranged in the drawing; the other end is connected with the oil pump 1 through a flange and a first bolt 2, and the left end in the figure is shown. In order to ensure the rigidity of the engine oil strainer, a fixed bracket 6 is arranged on the engine oil strainer, the bracket 6 is connected with the oil suction pipe 3 through a second bolt 4 and a third bolt 5, and the bracket is fixed on the lower plane of the engine body.
When the engine runs, the oil pump pumps the oil to each kinematic pair for lubrication. When the oil suction pipe 3 is arranged, one end of an oil outlet of the oil suction pipe is higher than the whole pipeline, so that the engine oil in the oil pump and the engine oil strainer flows back to the oil pan after the engine is stopped, at the moment, the oil is not reserved in the oil suction pipe 3, the oil pump needs to pump the required lubricating oil from the oil pan again to enter a lubricating position when the engine is started again, the response time of the oil pump is prolonged, and the oil pressure establishment time of the pipeline is prolonged.
In order to solve the above problem, the present embodiment provides an oil strainer, as shown in fig. 2, including:
the first oil suction pipe 8 is arranged on the oil pan 12, and an oil outlet of the first oil suction pipe 8 is used for being connected with an oil pump;
an oil outlet of the second oil suction pipe 9 is communicated with an oil inlet of the first oil suction pipe 8, a filter collector cover 10 and a filter screen 11 are arranged at the oil inlet, and the middle of the second oil suction pipe 9 is arched and the arched height is higher than that of the first oil suction pipe 8.
The first oil suction pipe 8 is arranged on the oil pan 12, and the oil outlet of the first oil suction pipe is used for being connected with an oil pump, so that the height of the oil outlet of the oil strainer is reduced. Meanwhile, the second suction pipe communicating with the first suction pipe 8 is provided with a filter cover 10 and a strainer 11, the filter cover 10 and the strainer 11 are immersed in the oil of the oil pan 12, and the second suction pipe 9 is arched in the middle and higher than the first suction pipe 8.
When the engine runs, the engine oil is sucked into the second oil suction pipe 9 and the first oil suction pipe 8 under the action of the engine oil pump. When the engine stops, the middle of the second oil suction pipe 9 is arched, the oil is prevented from flowing back to the oil pan 12 due to the arch, and the oil is temporarily stored in a pipeline between the oil pump and the arch of the second oil suction pipe 9. Therefore, the time for establishing the oil pressure can be effectively shortened when the engine is restarted, and the engine oil can reach the relevant lubricating position more quickly, so that the engine can be fully lubricated as soon as possible.
In order to prevent the oil from flowing back, it is understood that the middle of the second suction pipe 9 is arched, and the height of the middle arch of the second suction pipe 9 is at least higher than that of the first suction pipe 8, i.e. the lowest point of the outer wall of the arch of the second suction pipe 9 is higher than that of the highest point of the outer wall of the first suction pipe 8.
First oil suction pipe 8 and oil pan 12 integrated casting shaping, at the as-cast in-process of oil pan 12, first oil suction pipe 8 forms rather than casting together, and the partly lower tube wall that has constituteed first oil suction pipe 8 of oil pan has saved the work of follow-up independent setting pipeline to be favorable to setting up the oil drain plug screw.
The first suction pipe 8 is provided with an oil drain plug 7 at an oil pan 12 component thereof. When the engine needs to be changed, the engine oil temporarily stored in the pipeline between the engine oil pump and the arch part of the second oil suction pipe 9 can be discharged through the oil discharge screw plug 7.
A flange structure is cast at an oil inlet of the first oil suction pipe 8, an adaptive flange structure is arranged at an oil outlet of the second oil suction pipe 9, and the oil outlet of the second oil suction pipe 9 is detachably connected with the oil inlet of the first oil suction pipe 8 through a flange, so that the second oil suction pipe 9 can be detached independently, and the flange is sealed through an O-shaped sealing ring during flange connection.
In the embodiment, the second suction pipe 9 is generally in an inverted U shape, as shown in fig. 1, the left side of the second suction pipe 9 needs to be butted with the first suction pipe 8, and the left side pipeline is inclined to a certain degree, so that the pipeline is smoothly transited to the first suction pipe 8. The right side of the pipeline is more regular and vertical, and the filter cover 10 and the filter screen 11 are arranged on the side.
As shown in fig. 3, the second oil suction pipe 9 is inserted into the filter cover 10 and is non-rigidly connected, so that the connection between the second oil suction pipe 9 and the filter cover 10 has certain flexibility, thereby preventing the oil filter from generating local stress and further preventing the pipeline from being damaged by stress concentration.

The ring sleeve 13 is welded at the oil inlet of the second oil suction pipe 9, an annular groove is formed in the ring sleeve 13 and used for installing an O-shaped sealing ring, and the O-shaped sealing ring is matched with an annular matching surface of the annular insertion port to achieve good sealing.
The lower outer edge of the filter cover 10 extends outward to form connecting portions 17, and the connecting portions 17 are mounted on bosses 14 provided on the oil pan 12. In this embodiment, the connecting portion 17 is square, the number of the bosses 14 is four, and holes are formed at four corners of the square connecting portion and are fixed to the bosses 14 through the fourth bolts 15. It can be understood that the bosses have gaps between them, so that the oil in the oil pan is prevented from entering the oil strainer normally.
Filter screen 11 and collection filter cover 10 adaptation, filter screen 11 are placed between connecting portion 17 and boss 14, and filter screen 11 is equipped with a plurality of filtration holes, forms filtration space between filter screen 11 and the collection filter cover 10.
Example 2
The present embodiment provides a lubricating system for use in an engine employing the oil strainer of embodiment 1. The engine oil collector is connected with the engine oil pump, and when the engine runs, the engine oil pump pumps the engine oil to each kinematic pair for lubrication through the lubricating oil channel.
Example 3
The embodiment provides an engine, and the lubricating system of the engine is the lubricating system in the embodiment 2.
