Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is further described.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention provides a kind of oil filtering structure, is arranged between the bent axle 70 and oil pump (scheming not shown) of automobile, and for the impurity such as the iron filings in machine oil are got rid of, wherein, bent axle 70 is provided with center oilhole 71.The oil filtering structure that the present embodiment provides comprises the first housing 10, the second housing 20, multiple shank 40 and multiple valve block 50.
The first housing 10 is fixedly sleeved on the end of bent axle 70.The first housing 10 and the second housing 20 are fixedly connected to form a rotary shell 60, the inner oil storage cavity 61 that forms of rotary shell 60.The first housing 10 is connected with bent axle 70 center oilhole 71, so that machine oil can enter bent axle 70 center oilhole 71 in oil storage cavity 61.
The second housing 20 is offered a machine oil filler opening 21, and machine oil filler opening 21 is connected with oil storage cavity 61, and machine oil filler opening 21 is also for being connected with machine oil oil pump, so that the machine oil in oil pump enters in oil storage cavity 61 by machine oil filler opening 21.
The junction of the first housing 10 and the second housing 20 forms housing joint 30.As shown in Figure 2, housing joint 30 is a circular body, offers multiple impurity outfalls 31 on housing joint 30.
Shank 40 is arranged at housing joint 30, for the first housing 10 and the second housing 20 are fixed together.The central axis of shank 40 is parallel with the spin axis of bent axle 70, and shank 40 can be for example a straight pin.
Multiple valve blocks 50 are corresponding one by one with multiple shanks 40 and multiple impurity outfall 31, and one end of each valve block 50 is connected on corresponding shank 40, and can rotate around corresponding shank 40, the other end of valve block 50 is in the interior extension of oil storage cavity 61, and can be in the time being adjacent to the inwall of housing joint 30 the corresponding impurity outfall 31 of shutoff.Specifically, valve block 50 can be in the time that bent axle 70 rotates, and follows rotary shell 60 and rotates, and under the effect of off-line power, is adjacent to the inwall of housing joint 30, thus shutoff impurity outfall 31.In the time that bent axle 70 stops the rotation, under Action of Gravity Field, valve block 50 rotates with respect to shank 40, thereby opens impurity outfall 31, and like this, valve block and impurity outfall 31 form an one-way valve structures.
Oil filtering structure of the present invention, the iron filings that utilize per unit volume are different from engine oil quality, thus under the prerequisite of identical turning radius, the centrifugal force difference being subject to, thus iron filings are separated from the flow of machine oil.The iron filings of separating are rested on rotary shell 60, and in the time of engine stoping operation, when bent axle 70 stops the rotation, the one-way valve structures that the iron filings of these rotary shell 60 interior stops consist of valve block 50 and impurity outfall 31 is excreted to oil sump.
The working procedure of oil filtering structure of the present invention is as follows:
In engine operation process, machine oil arrives oil pump by fuel filter, machine oil enters from oil pump outlet the machine oil filler opening 21 that the second housing 20 is offered, because oil storage cavity 61 spaces in rotary shell 60 are larger, machine oil can not directly arrive bent axle 70 center oilhole 71, machine oil is in the oil storage cavity 61 of rotary shell 60, along with bent axle 70 drives the rotation of filtering mechanism.Because the engine oil quality in per unit volume is less than the quality of chip, so the centrifugal force difference being subject to.The centrifugal force that chip is subject to is larger, and impurity chip is transported to the edge of rotary shell 60, i.e. the inwall place of housing joint 30.Under the effect of centrifugal force, valve block 50 is combined closely with the inwall of housing joint 30, prevents lubricating oil leakage simultaneously.Thereby reach the effect that impurity is thrown to edge, and after oil flow rate increase, machine oil enters lubrication system by bent axle 70 center oilhole 71.
After engine stoping operation, after bent axle 70 stops the rotation, owing to there is no the effect of centrifugal force, under Action of Gravity Field, valve block 50 rotates around shank 40, and impurity outfall 31 is opened, at this moment impurity flows out by the impurity impurity outfall 31 of housing joint 30, flows to oil sump.Thereby reach the filtering effect to machine oil, increased the working life of filter cleaner simultaneously.
In the present embodiment, on the first housing 10, offer mounting hole 11, bent axle 70 ends are plugged in mounting hole 11 and are fixedly connected with the first housing 10.
In the present embodiment, the first housing 10 and the second housing 20 are all spherical crown shape, make rotary shell 60 roughly become the pie of hollow, thereby it are larger to make oil storage cavity 61 present space, intermediate portion, and space, edge is less.
In the present embodiment, the maximum that housing joint 30 is positioned at rotary shell 60 is outward through locating.
In the present embodiment, the quantity of valve block 50, shank 40 and impurity outfall 31 is 4, and evenly arranges in the sense of rotation along bent axle 70.Certainly, the quantity of valve block 50, shank 40 and impurity outfall 31 is not not limited to 4, and in other embodiments, its quantity can be adjusted according to actual needs.
In the present embodiment, one end that valve block 50 is connected with shank 40 forms a winding portion 51, and winding portion 51 is socketed on shank 40.
In the present embodiment, the shape of the inwall of the shape of one end that valve block 50 extends in oil storage cavity and housing joint 30 is suitable, thereby can better fit and seal, while preventing from rotating, and oil leakage.
The oil filtering structure of the embodiment of the present invention has the following advantages:
(1) utilize the rotating inertia force of bent axle 70, chip is rested on oil filtering structure of the present invention entering before oil pump, can improve preferably the working life of oil pump, increased the mission life-span of filter cleaner simultaneously, extended the replacement cycle.
(2) only 70 increase structures on bent axle of oil filtering structure of the present invention, do not need new drive mechanism, and structure is simpler, and practicability is stronger.
(3) described oil filtering structure can improve the life-span of oil filter, the phenomenons such as the rotor of engine oil pump wearing and tearing that minimizing caused because fuel filter lost efficacy, before entering oil pump, machine oil utilizes rotating inertia force filtering machine oil, through changing after depuration structure, engine oil impurity is filtered, reduce the wearing and tearing of rotor of engine oil pump, reduced the filtering amount of oil filter, the working life of having improved filter cleaner simultaneously.
