Description

Technical Field

[0001] This invention relates to the technical field of vehicle engineering, specifically to a filter, powertrain, and vehicle. Background Technology

[0002] The three-in-one powertrain integrates components such as the motor, reducer, and controller into one unit, sharing parts such as the housing and wiring harness, in order to achieve lightweighting, lower cost, and higher efficiency.

[0003] The three-in-one powertrain consists of a housing and an oil circuit system. The housing houses working parts such as gears, rotors, and stators, while the oil circuit system primarily serves for cooling and lubrication. During operation, the gears and rotor rotate within the housing. The oil circuit system sprays cooling and lubricating oil onto these components to ensure proper functioning. Currently, there are two possible layouts for the oil circuit system: one is to place it on the outer surface of the housing, which results in a larger overall space requirement and makes installation in a vehicle more difficult; the other is to place it inside the housing, but when this is done, the filter used to filter the oil becomes difficult to replace, and over time, the filter solution becomes clogged with impurities. Summary of the Invention

[0043] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] One embodiment of the present invention provides a filter for filtering impurities in cooling lubricating oil. The filter is a built-in filter disposed inside an oil chamber 3, wherein the oil chamber 3 can be an oil chamber 3 in a reducer or an oil chamber 3 in a three-in-one powertrain.

[0045] like Figures 1 to 12As shown, the filter includes a housing 1, a first oil plug 21, and a second oil plug 22. A first filter chamber 11 and a second filter chamber 12 are formed inside the housing 1. Both the first filter chamber 11 and the second filter chamber 12 are used to filter impurities in the cooling lubricating oil. The first filter chamber 11 and the second filter chamber 12 are spaced apart, but the first filter chamber 11 and the second filter chamber 12 are connected. The first filter chamber 11 is provided with a first inlet 111 and a first outlet 112. The cooling lubricating oil enters the first filter chamber 11 through the first inlet 111, is filtered, and then exits the first filter chamber 11 through the first outlet 112. The second filter chamber 12 is provided with a second inlet 121. The cooling lubricating oil enters the second filter chamber 12 through the second inlet 121, is filtered by the second filter chamber 12, flows into the first filter chamber 11, and then exits through the first outlet 112.

[0046] The inner wall of the oil chamber 3 is provided with a first oil hole 31 and a second oil hole 32. The first oil hole 31 and the second oil hole 32 are the oil drain holes of the oil chamber 3. When cooling and lubricating oil in the oil chamber 3 is needed, it can be discharged through the first oil hole 31 and the second oil hole 32. The first inlet 111 is correspondingly provided with the first oil hole 31, and the second inlet 121 is correspondingly provided with the second oil hole 32. The first oil plug 21 can block the first oil hole 31 and the second oil hole 32; the second oil plug 22 can simultaneously block the first oil hole 31 and the first inlet 111, and can simultaneously block the second oil hole 32 and the second inlet 121.

[0047] When the first oil plug 21 blocks the first oil hole 31, the second oil plug 22 blocks the second oil hole 32 and the second inlet 121. When the first oil plug 21 blocks the second oil hole 32, the second oil plug 22 blocks the first oil hole 31 and the first inlet 111.

[0048] That is, in this embodiment, the positions of the first oil plug 21 and the second oil plug 22 can be switched according to the actual situation. When the first filter chamber 11 needs to work, the first oil plug 21 is placed at the first oil hole 31, closing the first oil hole 31, but the first inlet 111 is in the open state; the second oil plug 22 is placed at the second oil hole 32, closing both the second oil hole 32 and the second inlet 121. When the second filter chamber 12 needs to work, the first oil plug 21 is placed at the second oil hole 32, closing the second oil hole 32, but the second inlet 121 is in the open state; the second oil plug 22 is placed at the first oil hole 31, closing both the first oil hole 31 and the first inlet 111.

[0049] The filter provided in this embodiment of the invention, by placing the filter inside the oil chamber 3, can prevent the filter element from being bumped or knocked, and at the same time reduce the size of the equipment (existing equipment, whether the filter is built-in or external, is equipped with an oil chamber 3); at the same time, by setting a first filter chamber 11 and a second filter chamber 12 that are connected inside the filter, and setting a first oil plug 21 and a second oil plug 22 to control the opening and closing of the first filter chamber 11 and the second filter chamber 12, when one of the filter chambers has a problem, the positions of the first oil plug 21 and the second oil plug 22 can be switched; and the two filter elements can be used alternately, which can also extend the service life of the filter.

[0050] The aforementioned equipment can be a speed reducer or a powertrain, etc.

[0051] Optionally, the first inlet 111 is coaxially arranged with the first oil hole 31, and the second inlet 121 is coaxially arranged with the second oil hole 32.

[0052] Optionally, in this embodiment, the first outlet 112 is connected to the oil pump. The cooling lubricating oil is filtered by the filter before entering the oil pump, which protects the oil pump and extends its service life.

[0053] Optionally, an elbow is also provided at the first outlet 112, and the first outlet 112 is connected to the oil pump through the elbow. By providing the elbow, it is convenient to adjust the position of the oil pump and to facilitate the installation of the oil pump.

[0054] like Figures 1 to 10 As shown, the outer casing 1 includes a first body 13 and a second body 14. Both the first body 13 and the second body 14 have a groove structure. The first body 13 and the second body 14 are arranged opposite to each other and connected to each other. A first filter chamber 11 and a second filter chamber 12 are formed between the first body 13 and the second body 14 at an interval. The first inlet 111 and the second inlet 121 are located on the first body 13, and the first outlet 112 is located on the second body 14. The first body 13 is disposed close to the inner wall of the oil cavity 3 and is connected to the inner wall of the oil cavity 3. A gap is formed between the inner wall of the oil cavity 3 and the outer wall of the first body 13 to allow cooling lubricating oil to flow through. At the same time, the first inlet 111 is coaxially arranged with the first oil hole 31, and the second inlet 121 is coaxially arranged with the second oil hole 32.

[0055] In this embodiment, by coaxially arranging the first inlet 111 with the first oil hole 31 and the second inlet 121 with the second oil hole 32, the second oil plug 22 can be easily disassembled and assembled.

[0056] Meanwhile, the first body 13 is located close to the inner wall of the oil cavity 3, which can prevent the filter from occupying too much space inside the oil cavity 3 and affecting the arrangement of the existing structure inside the oil cavity 3.

[0057] During use, cooling lubricating oil flows into the first inlet 111 or the second inlet 121 through the gap.

[0058] Optionally, the first body 13 is provided with a screw hole, and the first body 13 is fixed to the inner wall of the oil cavity 3 by screws.

[0059] like Figure 1 As shown, the first oil plug 21 is provided with a magnetic structure 23 at one end near the outer casing 1, and the magnetic structure 23 can generate magnetic force.

[0060] In this embodiment, since the first oil hole 31 is coaxial with the first inlet 111 and the second oil hole 32 is coaxial with the second inlet 121, the cooling lubricating oil will inevitably pass through the first oil plug 21 when it enters the filter. By providing a magnetic attraction structure 23 on the first oil plug 21, the magnetic force generated by the magnetic attraction structure 23 can attract iron filings and other materials, thus preventing iron filings from entering the filter and affecting the service life of the filter.

[0061] Optional, such as Figure 1 and Figure 12 As shown, the first oil plug 21 has a mounting groove 211 at one end near the outer shell 1, the magnetic structure 23 is a permanent magnet 231, the magnetic structure 23 is located in the mounting groove 211, and the permanent magnet 231 is flush with the inner wall of the oil cavity 3.

[0062] In this embodiment, the magnetic attraction structure 23 is a permanent magnet 231, which has a long service life and is not easily affected by the external environment.

[0063] Optionally, the magnetic structure 23 can also be an electromagnet, etc.

[0064] In this embodiment, the mounting groove 211 is opened at the end of the first oil plug 21. In order to avoid affecting the oil intake at the first inlet 111 and the second inlet 121, after the permanent magnet 231 is installed into the mounting groove 211, the surface of the permanent magnet 231 is flush with the inner wall of the oil cavity 3.

[0065] Specifically, the surface of the permanent magnet 231 is flush with the inner wall of the oil cavity 3 where the first oil hole 31 and the second oil hole 32 are provided.

[0066] The filter provided in this embodiment of the invention uses a permanent magnet 231 to attract iron filings in the cooling lubricating oil, preventing the iron filings from entering the filter along with the cooling lubricating oil. At the same time, the surface of the permanent magnet 231 is flush with the inner wall of the oil cavity 3 where the first oil hole 31 and the second oil hole 32 are provided, so as to avoid affecting the flow rate of the cooling lubricating oil in the filter.

[0067] like Figure 1 , Figure 11 and Figure 12 As shown, the first oil plug 21 has a columnar structure, including a first body 212. The cross-section of the first body 212, the first oil hole 31, and the second oil hole 32 have the same shape. The first body 212 is used to block the first oil hole 31 and the second oil hole 32.

[0068] The second oil plug 22 includes a second body 221 and a third body 222. The cross-section of the second body 221, the first oil hole 31, and the second oil hole 32 are identical in shape. The cross-section of the third body 222, the first inlet 111, and the second inlet 121 are identical in shape. The second body 221 is identical in shape to the first body 212 and is used to block the first oil hole 31 and the second oil hole 32. The third body 222 is used to block the first inlet 111 and the second inlet 121.

[0069] Optional, such as Figure 11 As shown, a sealing ring 223 is also provided on the surface of the third body 222.

[0070] The sealing ring 223 can be a silicone ring, a rubber ring, etc.

[0071] like Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, in the filter provided in this embodiment, the first filter chamber 11 and the second filter chamber 12 are separated by a partition 15. The partition 15 can be configured in various ways.

[0072] In one configuration of the partition 15, the partition 15 can be disposed on the first body 13. When the first body 13 and the second body 14 are connected, the partition 15 is inserted into the second body 14 to form a first filter cavity 11 and a second filter cavity 12 spaced apart between the first body 13 and the second body 14.

[0073] In one configuration of the partition 15, the partition 15 can be disposed on the second body 14. When the first body 13 and the second body 14 are connected, the partition 15 is inserted into the first body 13 to form a first filter cavity 11 and a second filter cavity 12 spaced apart between the first body 13 and the second body 14.

[0074] In one configuration of the partition 15, the partition 15 can be simultaneously provided on the first body 13 and the second body 14, and the partition 15 on the first body 13 and the partition 15 on the second body 14 are arranged opposite to each other. When the first body 13 and the second body 14 are connected, the partition 15 on the first body 13 abuts against the partition 15 on the second body 14, so as to form a first filter cavity 11 and a second filter cavity 12 that are spaced apart between the first body 13 and the second body 14.

[0075] like Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10 The partition 15 is also provided with a connecting structure, which is used to connect the first filter cavity 11 and the second filter cavity 12.

[0076] In this embodiment, the first filter chamber 11 and the second filter chamber 12 are separated by a partition 15 on the first body 13 and the second body 14. The structure is simple and easy to manufacture.

[0077] Optionally, in this embodiment, two sets of outer shells 1 can be set separately to form a first filter chamber 11 and a second filter chamber 12, and the first filter chamber 11 and the second filter chamber 12 can be connected by a pipeline.

[0078] like Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10 The first filter chamber 11 is provided with a first filter element 16, and the second filter chamber 12 is provided with a second filter element 17. The notch 151 is located between the first filter element 16 and the first outlet 112, and the notch 151 is located between the second filter element 17 and the first outlet 112.

[0079] In this embodiment, the first filter element 16 and the notch 151 are arranged sequentially along the direction from the first inlet 111 to the first outlet 112, or the second filter element 17 and the notch 151 are arranged sequentially along the direction from the first inlet 111 to the first outlet 112.

[0080] Specifically, in this embodiment, the notch 151 is disposed on the partition 15 located on the second body 14, and is located on the side of the partition 15 close to the inner wall of the second body 14.

[0081] Optionally, flow channels can also be formed on the second body 14 to increase the flow rate between the first filter chamber 11 and the second filter chamber 12.

[0082] In use, when the first filter element 16 is working and the second filter element 17 is on standby or damaged, some of the cooling lubricating oil in the first filter chamber 11 will enter the second filter chamber 12 through the notch 151. However, since the notch 151 is located between the first filter element 16 and the second body 14, the cooling lubricating oil entering the second filter chamber 12 is the cooling lubricating oil that has been filtered by the first filter element 16, and it will not affect the filtration effect of the second filter element 17. When the second filter element 17 is working and the first filter element 16 is on standby or damaged, the cooling lubricating oil in the second filter chamber 12 must enter the first filter chamber 11 through the notch 151 and then exit through the first outlet 112. Since the notch 151 is located between the second filter element 17 and the second body 14, all the cooling lubricating oil entering the first filter chamber 11 has been filtered by the second filter element 17 and will not affect the first filter element 16.

[0083] The filter provided in this embodiment of the invention has an oil chamber 3 with a bottom wall, and the filter is installed on the bottom wall of the oil chamber 3. The first oil plug 21 and the second oil plug 22 are both inserted from outside the oil chamber 3. The first oil hole 31 is located below the first inlet 111, and the second oil hole 32 is located below the second inlet 121.

[0084] When the first filter chamber 11 is working normally, the cooling lubricating oil flows into the first inlet 111 through the first oil plug 21. Iron filings in the cooling lubricating oil are attracted by the permanent magnet 231. After being filtered by the first filter element 16, the cooling lubricating oil enters the oil pump. The second oil plug 22 blocks the second oil hole 32 and the second inlet 121, and the second filter element 17 does not work.

[0085] When the cooling lubricating oil in the oil chamber 3 needs to be replaced or maintained, the first oil plug 21 and the second oil plug 22 are removed, and the cooling lubricating oil in the oil chamber 3 flows out through the first oil hole 31 and the second oil hole 32. At the same time, the operator can determine whether the position of the first oil plug 21 and the second oil plug 22 needs to be replaced according to the actual situation.

[0086] When the first filter element 16 fails, the positions of the first oil plug 21 and the second oil plug 22 are replaced. At this time, the cooling lubricating oil flows into the second inlet 121 through the first oil plug 21. The iron filings in the cooling lubricating oil are attracted by the permanent magnet 231. After passing through the second filter element 17, the cooling lubricating oil flows into the first filter chamber 11 through the notch 151, and then enters the oil pump through the first outlet 112.

[0087] The filter provided in this embodiment of the invention is installed inside the oil chamber 3, which can reduce the risk of the filter being bumped or knocked. At the same time, when changing the cooling lubricating oil, the positions of the first oil plug 21 and the second oil plug 22 can be changed simultaneously, so that the first filter element 16 and the second filter element 17 can be used alternately, thus extending the service life of the entire filter.

[0088] Another embodiment of the present invention also provides a powertrain, which is a three-in-one powertrain, including a housing, wherein the oil chamber 3 is formed within the housing.

[0089] The powertrain includes all the advantages of the filters mentioned above, which will not be repeated here.
