[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 and Figure 2 As shown, an oil filter assembly includes: an oil filter housing 8, a filter element 6 and a flange cover 1.

[0027] Among them, the filter element 6 is coaxially arranged on the circumferential inner side of the oil filter housing 8, and a lubricating oil input channel is formed between the filter element 6 and the filter element 6 housing, and a lubricating oil output channel is formed inside the filter element 6. After the lubricating oil enters the input channel, it is filtered by the filter element 6 and enters the output channel, that is, the middle part of the filter element 6, and the lubricating oil is filtered by the filter element 6.

[0028] A flange cover 1 is provided at the lower end of the oil filter housing 8, and a first magnet 4 and a second magnet 3 are provided on the inner side of the flange cover 1, wherein the first magnet 4 is provided on the circumferential inner side of the filter element 6, and the second magnet 3 is provided between the filter element 6 and the housing of the filter element 6. Specifically, the first magnet 4 is provided inside the filter element 6 and is located at the lower end of the filter element 6, that is, the lower end of the input channel, and the second magnet 3 is sleeved and provided outside the filter element 6 and is located at the lower end of the filter element 6, that is, the lower end of the output channel.

[0029] During use, after the lubricating oil enters the input channel, the second magnet 3 in the input channel initially absorbs the metal chips and metal burrs in the lubricating oil to prevent the metal chips and metal burrs from being absorbed on the filter screen for a long time and causing the filter screen to be blocked, thereby effectively improving the filtering efficiency of the filter element 6. After being filtered by the filter element 6, the lubricating oil enters the output channel, and the second magnet 3 in the output channel further absorbs the metal chips and metal burrs in the lubricating oil to remove the metal impurities in the lubricating oil as much as possible, thereby effectively improving the quality of the lubricating oil.

[0030] The inner side of the flange cover 1 is provided with a first stepped groove 9, which is in an annular shape as a whole, and the bottom surface of the first stepped groove 9 abuts against the lower end surface of the oil filter housing 8, and the side wall of the first stepped groove 9 abuts against the inner side wall of the oil filter housing 8, thereby sealing the flange cover 1 and the oil filter housing 8. In addition, a first sealing ring 2 is provided in the first stepped groove 9, which is in an annular shape as a whole and is arranged between the first stepped groove 9 and the oil filter housing 8. Specifically, the bottom surface of the first sealing ring 2 abuts against the bottom surface of the first stepped groove 9, and the top surface of the first sealing ring 2 abuts against the lower end surface of the oil filter housing 8, effectively improving the sealing between the flange cover 1 and the oil filter housing 8.

[0031] It should be noted that the first sealing ring 2 is made of a flexible material and has a certain elastic deformation capability. Preferably, the first sealing ring 2 is made of a rubber material. The first sealing ring 2 made of a rubber material enables the flange cover 1 and the oil filter housing 8 to have better sealing performance, better corrosion resistance, and longer service life. Of course, the first sealing ring 2 can also be made of a silicone material, the purpose of which is to increase the sealing performance between the flange cover 1 and the oil filter housing 8 and ensure that the lubricating oil is sealed inside the oil filter housing 8 without leakage.

[0032] A second stepped groove 10 is provided on the inner side of the flange cover 1, and the second magnet 3 is arranged in the second stepped groove 10. The second stepped groove 10 is generally ring-shaped. It should be noted that the second magnet 3 is generally ring-shaped and matched with the second stepped groove 10 to ensure that the second magnet 3 can be stably clamped in the second stepped groove 10. The bottom surface of the second stepped groove 10 abuts the bottom surface of the second magnet 3, the side wall of the second stepped groove 10 abuts the inner side wall of the second magnet 3, the inner side wall of the oil filter housing 8 abuts the outer side wall of the second magnet 3, and the outer side wall of the lower end of the filter element 6 abuts the inner side wall of the second magnet 3. During assembly, after the filter element 6 is installed on the inner side of the flip cover, the second magnet 3 is assembled, and finally the oil filter housing 8 is matched with the first stepped groove 9, so that the second magnet 3 can be stably clamped between the oil filter housing 8 and the filter element 6.

[0033] A second sealing ring 5 is provided on the lower end surface of the filter element 6. Specifically, the second sealing ring 5 is in a ring shape as a whole. The bottom surface of the second sealing ring 5 abuts against the inner side surface of the flange cover 1, and the top surface of the second sealing ring 5 abuts against the lower end surface of the filter element 6, which is used to improve the sealing between the flange cover 1 and the filter element 6, and prevent the lubricating oil from directly entering the interior of the filter element 6 from the input channel through the lower end of the filter element 6, thereby affecting the quality of the lubricating oil.

[0034] It should be noted that the second sealing ring 5 is also made of a flexible material and has a certain elastic deformation capability. Preferably, the second sealing ring 5 is made of a rubber material. The second sealing ring 5 made of a rubber material enables the flange cover 1 and the oil filter housing 8 to have a better seal, better corrosion resistance, and a longer service life. Of course, the second sealing ring 5 can also be made of a silicone material, the purpose of which is to increase the seal between the filter element 6 and the flange cover 1, ensure that the lubricating oil is sealed inside the filter element 6, and avoid leakage into the input channel.

[0035] In one embodiment of the utility model, the inner side of the flange cover 1 is provided with an assembly groove 11, and the first magnet 4 is connected in the assembly groove 11. Preferably, the first magnet 4 is cylindrical, and the corresponding assembly groove 11 is cylindrical. Of course, the first magnet 4 can also be prism-shaped, and the corresponding assembly groove 11 is prism-shaped. The lower end of the first magnet 4 is consistent with the shape of the assembly groove 11, and the overall height of the first magnet 4 is greater than the depth of the assembly groove 11, ensuring that the first magnet 4 can be stably engaged in the assembly groove 11, and the side wall of the assembly groove 11 fits with the outer side wall of the first magnet 4, so that the first magnet 4 can be stably fixed inside the filter element 6. It should be noted that the assembly groove 11 is coaxially arranged with the filter element 6, and the metal impurities in the lubricating oil that enters the filter element 6 from the circumference of the filter element 6 can be uniformly adsorbed by the first magnet 4, thereby improving the impurity removal effect of the lubricating oil.

[0036] In addition, a metal block can be embedded in the bottom surface of the assembly groove 11. After the first magnet 4 is prevented from entering the assembly groove 11, the first magnet 4 has a certain adsorption force on the metal block, thereby increasing the connection strength of the first magnet 4 in the assembly groove 11. When the oil filter assembly encounters bumps or vibrations, the first magnet 4 can still be stably connected in the assembly groove 11.

[0037] Among them, the end face of the second end of the filter element 6 is provided with a third sealing ring 7, and the bottom surface of the third sealing ring 7 abuts against the end face of the second end of the filter element 6. It should be noted that the third sealing ring 7 is also made of a flexible material and has a certain elastic deformation ability. Preferably, the third sealing ring 7 is made of a rubber material. The third sealing ring 7 made of rubber material enables the connection between the filter element 6 and the upper accessories to have better sealing performance. Of course, the third sealing ring 7 can also be made of a silicone lamp material, the purpose of which is to increase the sealing performance between the filter element 6 and the upper accessories, ensure that the lubricating oil is sealed inside the filter element 6, and avoid leakage into the input channel.

[0038] In summary, by providing the first sealing ring 2 in the first step groove 9, the second sealing ring 5 on the lower end surface of the filter element 6, and the third sealing ring 7 on the upper end surface of the filter element 6, the sealing effect between the various components inside the oil filter assembly can be effectively increased, thereby avoiding leakage of lubricating oil between the various components and improving the filtering effect of the oil filter assembly on the lubricating oil.

[0039] In one embodiment of the utility model, a plurality of lugs are integrally arranged on the outer peripheral side of the flange cover 1. Specifically, three lugs are arranged in an array on the outer peripheral side of the flange cover 1. When the flange cover 1 is pressed, the three lugs distribute the pressing force of the flange cover 1 in a circumferential manner, avoiding the angle of the force being tilted when the flange cover 1 is pressed, thereby effectively improving the sealing effect between the flange cover 1 and the oil filter housing 8. In addition, the surface of each lug is provided with an ear hole, which passes through the flange cover 1, and the bolt rod passes through the ear hole to connect the flange cover 1 to the housing of the gearbox.

[0040] When the utility model is used, the lubricating oil enters the input channel. Under the adsorption effect of the second magnet 3, the metal chips and metal burrs mixed in the lubricating oil gradually fall to the bottom of the input channel and are adsorbed on the surface of the second magnet 3. At this time, there is still a part of metal chips and metal burrs with smaller diameters in the lubricating oil entering the interior of the filter element 6, that is, the output channel, along with the lubricating oil. The second magnet 3 in the output channel further adsorbs the metal chips and metal burrs mixed in the lubricating oil, removes the metal impurities in the lubricating oil as much as possible, and effectively improves the quality of the lubricating oil.

[0041] In summary, the oil filter assembly absorbs metal chips and metal burrs in the lubricating oil through the first magnet 4 and the second magnet 3, preventing the metal chips and metal burrs from being absorbed on the filter for a long time and causing the filter to be blocked, effectively improving the filtering efficiency of the filter element 6 and improving the quality of the lubricating oil.

[0042] In addition to the above-mentioned oil filter assembly, the present invention also provides a gearbox including the oil filter assembly disclosed in the above-mentioned embodiment. For the structures of other parts of the gearbox, please refer to the prior art and will not be described in detail herein.

[0043] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0044] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
