Abstract
Description
Technical Field
[0001] This application belongs to the field of vehicle technology, and more specifically, relates to a transmission magnet mounting structure, a transmission, and a vehicle. Background Technology
[0002] During operation, wear on the transmission shaft and gears will produce iron filings. These iron filings will accumulate in the oil, affecting the oil pump's performance, causing abnormal noises, and causing wear on the gear pairs and bearings, thus reducing their lifespan.
[0003] In existing technologies, magnets are usually installed inside the transmission housing to attract and collect iron filings. During installation, the magnets are usually placed in a limiting groove inside the housing for positioning. However, this method results in poor magnet stability and insecure fixation. Alternatively, the magnets can be fixed to the housing using a carrier plate and bolts. This method is inconvenient for disassembly and assembly, and the magnets have a small adsorption area, which affects the collection of iron filings. Utility Model Content
[0004] The purpose of this application is to provide a transmission magnet mounting structure, transmission, and vehicle, which aims to ensure the magnet adsorption effect while improving the stability and reliability of the magnet and making the magnet easy to install and remove.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, a transmission magnet mounting structure is provided, comprising:
[0007] The mounting housing is open on one side, and the open side of the mounting housing is used to connect to the closed housing; the inner shell wall of the mounting housing is provided with a limiting groove with an opening facing the open side, and the two opposite groove sidewalls of the limiting groove are provided with mounting notches with openings facing the open side, and the mounting notches extend away from the open side;
[0008] The magnet assembly includes an adsorption magnet and two sets of disassembly posts. The adsorption magnet has elastic sides on opposite sides, and the two sets of disassembly posts are correspondingly arranged on the two sets of elastic sides, and both extend away from the adsorption magnet.
[0009] Among them, the two sets of disassembly and assembly columns are used to slide from the opening of the mounting slot to the bottom of the mounting slot, so that the two elastic sides drive the magnet assembly to be correspondingly locked in the limiting groove, and an oil passage gap is left between the bottom of the adsorption magnet and the inner shell wall of the mounting housing.
[0010] Compared with the prior art, the solution shown in this application embodiment can install the magnet assembly by setting a limiting groove. Furthermore, the magnet assembly has two elastic sides that are engaged with the sidewalls of the limiting groove, increasing the reliability of the connection between the magnet assembly and the limiting groove. Additionally, an installation notch is provided on the sidewall of the limiting groove to limit the installation and removal of the magnet assembly, thereby increasing the limiting of the adsorbed magnet and improving the stability and reliability of the magnet connection. Secondly, the opening of the limiting groove faces the open side of the mounting housing, facilitating the adsorption of the magnet. The magnet enters from the opening side of the limiting groove, and the opening of the mounting notch faces the open side of the mounting housing, facilitating the entry of the disassembly column from the opening side of the mounting notch. During disassembly, the magnet assembly is also removed from the open side, thus facilitating the installation and removal of the magnet assembly. An oil passage gap is left between the bottom of the adsorption magnet and the inner wall of the mounting housing to increase the contact area between the adsorption magnet and the oil, thereby ensuring the adsorption effect of the adsorption magnet. Therefore, the transmission magnet mounting structure provided in this application can increase the stability and reliability of the magnet assembly connection while ensuring the adsorption effect, and facilitate disassembly and assembly.
[0011] In conjunction with the first aspect, in one possible implementation, the mounting housing includes a first connecting wall opposite to the enclosed housing, and a second connecting wall for connecting to the enclosed housing;
[0012] The second connecting wall is provided with two sets of parallel and spaced-apart limiting plates, and each limiting plate is provided with an installation notch;
[0013] The limiting groove is formed between the two opposite sides of the two limiting plates, the first connecting wall, and the second connecting wall.
[0014] By creating a limiting groove between the limiting plate and the first connecting wall and the second connecting wall, the magnet assembly can be disassembled and assembled by simultaneously fastening the disassembly and assembly column after it slides into the installation slot, thus improving the convenience of disassembly and assembly of the magnet assembly.
[0015] In some embodiments, the limiting plate and the mounting housing are integrally cast structures;
[0016] Each of the limiting plates is provided with a processing groove, which is recessed from the top of the limiting plate toward the second connecting wall, and the processing groove extends through both sides of the limiting plate along the axial direction of the disassembly column.
[0017] By integrally casting the limiting plate and the mounting housing, the limiting plate and the mounting housing can be machined as a single unit, improving processing efficiency. The inclusion of machining grooves ensures a tight fit between the limiting plate and the elastic side.
[0018] For example, one end of the processing groove is close to the bottom of the mounting notch, and the other end extends toward the root of the limiting plate in the direction of the first connecting wall.
[0019] By setting the extension direction of the machining groove, the installation slot is prevented from being accidentally damaged during machining; at the same time, the limiting function of the limiting plate is guaranteed.
[0020] In some embodiments, the elastic side is provided with a mating mounting groove, one end of which is close to the disassembly post and the other end extends to the machining groove.
[0021] By setting a fitting mounting groove, the compressive stress can be released at the fitting mounting groove after the elastic side deforms. The fitting mounting groove and the machining groove cooperate to reduce the compressive force of the magnet assembly at the fitting mounting groove and the machining groove, thereby relaxing the elastic side at this point and forming a limit.
[0022] In conjunction with the first aspect, in one possible implementation, the adsorption magnet includes multiple adsorption layers spaced apart vertically, with each of the elastic edges connected to the multiple adsorption layers respectively; a through gap suitable for oil flow is left between each two adjacent adsorption layers.
[0023] By setting multiple adsorption layers and through gaps, the adsorption effect of the magnet assembly can be guaranteed.
[0024] In some embodiments, each adsorption layer is a grid structure, and in the vertical direction, the transverse and longitudinal grids of the grid structure are partially staggered.
[0025] By setting the adsorption layer as a grid structure, the adsorption effect of the adsorption magnet is further improved.
[0026] For example, the disassembly column is an elastic column, and the disassembly column and the elastic side are an integral injection-molded structure.
[0027] By setting the disassembly column as a flexible column, it is easy for the disassembly column to be clamped and limited with the installation slot, ensuring the stability and reliability of the disassembly column connection.
[0028] Secondly, this application also provides a transmission, characterized in that it includes the above-described transmission magnet mounting structure.
[0029] The transmission provided in this application, by adopting the above-mentioned transmission magnet mounting structure, has all the beneficial effects of the transmission magnet mounting structure. It can improve the connection stability and reliability of the magnet mounting structure while ensuring the adsorption effect of the magnet, and improve the convenience of disassembling and assembling the magnet assembly.
[0030] Thirdly, this application also provides a vehicle including the aforementioned transmission.
[0031] The vehicle provided in this application, having the aforementioned transmission, possesses all the beneficial effects of that transmission. Due to the stable connection of the magnet mounting structure and the presence of a bottom oil passage gap, the magnet's adsorption effect is guaranteed, extending the transmission's service life. Furthermore, it facilitates the removal and installation of the magnet inside the transmission, offering high ease of disassembly and assembly. Attached Figure Description

[0037] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0038] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0039] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0040] In addition, the inner shell wall of the mounting housing 1 defined in the embodiments of this application is relative to the outer shell wall of the mounting housing 1. The mounting housing 1 has an accommodating space inside, and the magnet assembly 3, the gear structure for realizing speed change, and the transmission shaft are all located in the mounting space. The side facing the accommodating space is the inner shell wall, and the side away from the accommodating space is the outer shell wall.
[0041] In the prior art, to achieve the limiting of the adsorption magnet 31, one method is to directly snap the adsorption magnet 31 into the set receiving groove, or snap it into the joint surface between the two shells. In this method, when the adsorption magnet 31 is fixed, the bottom of the adsorption magnet 31 contacts the bottom of the receiving groove, which affects the adsorption effect of the adsorption magnet 31. If there is a gap, the adsorption magnet 31 is prone to shaking, resulting in unstable fixation.
[0042] In another method, the carrier plate is fixed to the adsorption magnet 31, and then the carrier plate and the inner wall of the housing are fixed with bolts. The carrier plate will also affect the adsorption effect of the adsorption magnet 31. Although the fixation is reliable, when removing the carrier plate, it is necessary to use tools such as wrenches to remove the bolts, which is more complicated.
[0043] Please refer to the following: Figures 1 to 3 The present application will now describe the transmission magnet mounting structure, transmission, and vehicle provided. The transmission magnet mounting structure includes a mounting housing 1 and a magnet assembly 3. The mounting housing 1 is open on one side, and the open side 13 of the mounting housing 1 is used to connect to the closed housing. The inner wall of the mounting housing 1 is provided with a limiting groove 14 with the opening facing the open side 13. The two opposite groove sidewalls of the limiting groove 14 are provided with mounting notches 21 with the opening facing the open side 13. The mounting notches 21 extend away from the open side 13. The magnet assembly 3 includes an adsorption magnet 31 and two sets of disassembly posts 32. The adsorption magnet 31 has elastic sidewalls 33 on opposite sides. The two sets of disassembly posts 32 are correspondingly provided on the two sets of elastic sidewalls 33 and both extend away from the adsorption magnet 31. The two sets of disassembly posts 32 are used to slide from the opening of the mounting notch 21 to the bottom of the mounting notch 21 so that the two elastic sidewalls 33 drive the magnet assembly 3 to be correspondingly locked in the limiting groove 14. An oil passage gap is left between the bottom of the adsorption magnet 31 and the inner wall of the mounting housing 1.
[0044] Specifically, when achieving the clamping form between the elastic side 33 and the groove wall of the limiting groove 14, the two sets of elastic side 33 and the corresponding two groove side walls of the limiting groove 14 can be pressed against each other by interference fit, so as to ensure that the elastic side 33 receives the squeezing force during installation, thereby achieving the clamping and limiting function.
[0045] It should be understood that if the adsorption magnet 31 is not installed stably and shakes, it will generate noise and affect the flow of internal oil. Furthermore, if the adsorption magnet 31 shakes and comes into contact with the inner wall of the housing, it will affect the adsorption of iron filings. In this application, a limiting groove 14 is provided to install the magnet assembly 3. The elastic side 33 of the magnet assembly 3 is correspondingly and tightly engaged with the side wall of the limiting groove 14, increasing the reliability of the connection between the magnet assembly 3 and the limiting groove 14. Therefore, shaking of the adsorption magnet 31 can be avoided, ensuring the adsorption effect.
[0046] Meanwhile, this application also includes a disassembly column 32. The cooperation between the disassembly column 32 and the mounting slot 21 not only increases the limit on the adsorption magnet 31 and improves the stability and reliability of the connection of the adsorption magnet 31, but also achieves the above-mentioned oil passage gap by setting the height of the mounting slot 21, thereby facilitating the passage of oil through the oil passage gap, thereby increasing the adsorption area between the oil and the adsorption magnet 31 and ensuring the adsorption effect of iron filings.
[0047] It should be noted that the connection structure and installation method between the mounting housing 1 and the closed housing are existing technologies in the field. After the closed housing is installed on the open side 13 of the mounting housing 1, the magnet assembly 3 can be limited between the mounting housing 1 and the closed housing, preventing the magnet assembly 3 from moving between the first connecting wall 11 of the mounting housing 1 and the closed housing.
[0048] Specifically, the disassembly column 32 can be one of a circular, square, or triangular cross-section; preferably, the disassembly column 32 is a cylinder, which can reduce the friction between the disassembly column 32 and the wall of the mounting slot 21 during the disassembly process, thereby reducing the disassembly resistance.
[0049] Optionally, the adsorption magnet 31 has a rectangular cross-section structure with a large cross-sectional area. The two opposite sides are the adsorption sides, and the elastic side 33 is provided on the other four sides to ensure the connection strength of the adsorption magnet 31. Alternatively, the elastic side 33 can be provided on only two opposite sides. The specific arrangement of the elastic side 33 can be set according to actual needs.
[0050] For example, when the actual size of the magnet assembly 3 is small, a detachable sealing plate can be provided between the opening side of the limiting groove 14 and the closed housing. The sealing plate is used to close the limiting groove 14 after the magnet assembly 3 is installed, so as to ensure the connection reliability of the magnet assembly 3.
[0051] Compared with the prior art, the transmission magnet mounting structure provided in this application can install the magnet assembly 3 by setting a limiting groove 14. The magnet assembly 3 has two elastic sides 33, which are engaged with the sidewalls of the limiting groove 14 to increase the reliability of the connection between the magnet assembly 3 and the limiting groove 14. Furthermore, a mounting notch 21 is provided on the sidewall of the limiting groove 14 to limit the mounting post 32 of the magnet assembly 3, thereby increasing the limiting of the adsorption magnet 31 and improving the stability and reliability of the connection of the adsorption magnet 31. Secondly, the opening of the limiting groove 14 faces the open side 13 of the mounting housing 1. The magnet 31 is easily accessible from the opening side of the limiting groove 14, and the opening of the mounting notch 21 faces the open side 13 of the mounting housing 1, facilitating the entry of the disassembly post 32 from the opening side of the mounting notch 21. During disassembly, the magnet assembly 3 is also easily removed from the open side 13, thus facilitating the installation and removal of the magnet assembly 3. An oil passage gap is left between the bottom of the magnet 31 and the inner wall of the mounting housing 1 to increase the contact area between the magnet 31 and the oil, thereby ensuring the adsorption effect of the magnet 31. Therefore, the transmission magnet mounting structure provided in this application can increase the stability and reliability of the magnet assembly 3 connection while ensuring the adsorption effect, and facilitates disassembly and assembly.
[0052] As a specific embodiment of the aforementioned limiting groove 14, a mounting bracket is provided on the mounting housing 1. After the mounting housing 1 is cast, the mounting bracket is fixed to the inner wall of the mounting housing 1 by means of threaded connectors or welding. The aforementioned limiting groove 14 is provided on the mounting bracket, and the magnet assembly 3 is limited within the limiting groove 14.
[0053] Please see Figure 1 In some possible embodiments, the mounting housing 1 includes a first connecting wall 11 opposite to the closed housing and a second connecting wall 12 for connecting to the closed housing; the second connecting wall 12 is provided with two sets of parallel and spaced limiting plates 2, each limiting plate 2 is provided with a mounting notch 21; wherein, the two limiting plates 2 are surrounded by limiting grooves 14 between their opposite sides, the first connecting wall 11 and the second connecting wall 12.
[0054] It should be noted that the limiting groove 14 formed by the two limiting plates 2 on opposite sides, the first connecting wall 11 of the mounting housing 1, and the second connecting wall 12 of the mounting housing 1 has two open sides 13. One of the open sides 13, the one facing the closed housing, is defined as the first open side 13, and the other open side 13 is defined as the second open side. The second open side is the side opposite to the second connecting wall 12 of the mounting housing 1. For ease of explanation, unless otherwise specified, all open sides 13 mentioned in this specification refer to the first open side 13.
[0055] It should be understood that the second connecting wall 12 of the mounting housing 1 is provided with two sets of parallel and spaced limiting plates 2, and each limiting plate 2 is provided with a mounting notch 21. This structure clarifies the formation method of the limiting groove 14, that is, the limiting groove 14 is formed between the opposite sides of the two limiting plates 2, the first connecting wall 11 of the mounting housing 1, and the second connecting wall 12 of the mounting housing 1, which helps to understand and manufacture the transmission magnet mounting structure.
[0056] By creating a limiting groove 14 between the limiting plate 2 and the first connecting wall 11 and the second connecting wall 12 of the mounting housing 1, the disassembly and assembly of the magnet assembly 3 can be achieved by simultaneously fastening the disassembly and assembly of the disassembly and assembly of the magnet assembly 3 after the disassembly and assembly column 32 slides into the mounting notch 21, thereby improving the convenience of disassembly and assembly of the magnet assembly 3.
[0057] Optionally, a limiting tongue 15 is provided at the second open side; preferably, one end of the limiting tongue 15 is connected to the first connecting wall 11 of the mounting housing 1, and the other end extends to the top of the magnet assembly 3; further, the limiting tongue 15 and the mounting housing 1 are integrally cast structures.
[0058] It should be noted that a gap suitable for oil flow is left between the limiting tongue 15 and the top of the magnet assembly 3. Since the magnet assembly 3 has achieved stable positioning after being limited in the mounting slot 21 by the disassembly post 32, the positioning stability of the magnet assembly 3 is not affected even if there is a gap between the limiting tongue 15 and the top of the magnet assembly 3. The limiting tongue 15 is used to achieve a double guarantee for the positioning of the magnet assembly 3. After the mounting slot 21 on the limiting plate 2 is damaged, the magnet assembly 3 can be limited in the aforementioned limiting groove 14. When the mounting slot 21 is damaged, the magnet assembly 3 will shake between the limiting tongue 15 and the bottom of the limiting groove 14 and produce abnormal noise. The operator can open the mounting housing 1 and directly find the magnet assembly 3 in the corresponding limiting groove 14. Therefore, the existence of the limiting tongue 15 can prevent the magnet assembly 3 from dislodging from the limiting groove 14 and damaging the transmission gear and transmission shaft after the mounting slot 21 is damaged.
[0059] For example, the two sets of limiting plates 2 can be fixed to the first connecting wall 11 or the second connecting wall 12 of the mounting housing 1 by means of threaded connection or welding, so that the limiting plates 2, the second connecting wall 12 of the mounting housing 1, and the first connecting wall 11 of the mounting housing 1 form the aforementioned limiting groove 14. To further realize the limiting function of the limiting plates 2, optionally, the two limiting plates 2 can be slidably connected to the mounting housing 1 so as to adjust the distance between the two limiting plates 2, thereby clamping the magnet assembly 3 between the two limiting plates 2.
[0060] For example, the two sets of limiting plates 2 can be fixed to the inner shell wall of the closed shell by means of detachable connection such as threaded connection, and extend towards the first connecting wall 11 of the mounting shell 1, so that the limiting plates 2, the second connecting wall 12 of the mounting shell 1 and the first connecting wall 11 of the mounting shell 1 form the limiting groove 14.
[0061] Optionally, reinforcing ribs are provided on the outer sides of the two opposing limiting plates 2. The reinforcing ribs increase the strength and rigidity of the limiting plates 2, preventing deformation during the installation and disassembly of the magnet assembly 3, which would affect the installation and limiting effect of the magnet assembly 3. Specifically, the reinforcing ribs are positioned between the mounting notch 21 and the machining groove 22; the shape of the reinforcing ribs can be triangular, rectangular, or trapezoidal, and can be rationally designed according to the structure and stress conditions of the limiting plates 2. For example, multiple triangular reinforcing ribs can be spaced along the length of the outer side of the limiting plates 2, with the right-angled sides of the triangles connected to the limiting plates 2 and the second connecting wall 12 of the mounting housing 1, respectively. This effectively enhances the strength of the limiting plates 2 without excessively increasing their weight.
[0062] Please see Figure 2 In some embodiments, the limiting plate 2 and the mounting housing 1 are integrally cast structures; each limiting plate 2 is provided with a processing groove 22, which is recessed from the top of the limiting plate 2 toward the second connecting wall 12 of the mounting housing 1, and the processing groove 22 passes through both sides of the limiting plate 2 along the axial direction of the disassembly column 32.
[0063] On the one hand, by casting the limiting plate 2 and the mounting housing 1 as a single unit, it is convenient to process the limiting plate 2 and the mounting housing 1 as a single unit, thereby improving processing efficiency. On the other hand, the integral casting of the limiting plate 2 and the mounting housing 1 ensures the integrity and strength of the structure, reduces the number of parts, and lowers the assembly difficulty and cost.
[0064] By setting the machining groove 22, the tightness of the engagement between the limiting plate 2 and the elastic side 33 is ensured. Each limiting plate 2 is provided with a machining groove 22, which is recessed from the top of the limiting plate 2 toward the second connecting wall 12 of the mounting housing 1, and extends through both sides of the limiting plate 2 along the axial direction of the disassembly column 32. This provides positioning and connection for the subsequent mating mounting groove 331 on the elastic side 33, which helps to achieve a better fit between the magnet assembly 3 and the limiting plate 2.
[0065] It should be understood that, due to the demolding issue, the limiting plate 2 is an integral rib-like structure cast to the first connecting wall 11. At this time, the inner side of the limiting plate 2 is completely locked with the elastic side 33 of the magnet assembly 3. Therefore, the limiting groove 14 mainly plays a locking role on the elastic side 33. The presence of the processing groove 22 enables the limiting function of the two limiting plates 2. Specifically, during the assembly of the magnet assembly 3, the portion of the limiting plate 2 that forms the mounting notch 21 first presses the elastic side 33. Because the elastic side 33 is elastic, it is compressed inward under the pressing force of the limiting plate 2. At this time, the elastic side 33 is compressed while being assembled inward. When the elastic side 33 continues to be installed to the processing groove 22, it is released from the pressing of the limiting plate 2, allowing the compressed portion of the elastic side 33 to be released into the processing groove 22. This release portion of the elastic side 33 is then limited within the processing groove 22, thereby preventing the magnet assembly 3 from detaching and improving the stability of the installation. When it is necessary to remove the magnet assembly 3, since the elastic side 33 is elastic, a large pulling force can be applied, so that the part released in the processing groove 22 is compressed again under the pressure of the groove wall of the processing groove 22, and then pulled out of the limiting groove 14.
[0066] Furthermore, the processing groove 22 also has the function of guiding oil. When the transmission is running, the oil with iron filings flows in from both sides of the two processing grooves 22, and after merging, it flows through the inside of the adsorption magnet 31. During this process, the oil with iron filings flows fully through the upper and lower surfaces of the adsorption magnet 31, and the iron filings are fully captured or adsorbed by the adsorption side of the magnet.
[0067] Specifically, during casting, the two sets of limiting plates 2 can be extended from the first open side 13 to the first connecting wall 11 of the mounting housing 1, that is, the root of the limiting plate 2; then, a machining groove 22 is formed on the limiting plate 2 by a cutting tool, forming the structure in this application.
[0068] Please see Figure 2 For example, one end of the processing groove 22 is close to the bottom of the mounting groove 21, and the other end extends toward the root of the limiting plate 2 in the direction of the first connecting wall 11 of the mounting housing 1.
[0069] By setting the extension direction of the processing groove 22, the installation notch 21 is not accidentally damaged during processing. At the same time, since the processing groove 22 starts from the bottom of the notch near the installation notch 21 and extends to the root of the limiting plate 2, the processing groove 22 can have a certain degree of friction, which can increase the limiting length of the elastic side 33 and ensure the limiting strength of the limiting plate 2.
[0070] Specifically, during the machining of the groove 22, a cutting tool is used to cut the two limiting plates 2 in half, and machining continues to the root. The remaining front ends of the two limiting plates 2 form limiting ribs, and the mounting notch 21 is set on the limiting ribs. Preferably, during machining, machining should avoid extending from the root of the machining groove 22 towards the mounting notch 21.
[0071] Furthermore, the processing groove 22 is recessed downward to the bottom of the magnet assembly 3 so that the oil can enter the limiting groove 14 from the bottom of the recess of the processing groove 22 and come into contact with the adsorption magnet 31.
[0072] Please see Figure 3 In some embodiments, the elastic side 33 is provided with a mating mounting groove 331, one end of which is close to the disassembly post 32, and the other end extends to the processing groove 22.
[0073] By setting the mounting groove 331, the compressive stress can be released at the mounting groove 331 after the elastic side 33 deforms. The mounting groove 331 cooperates with the processing groove 22 to reduce the compressive force of the magnet assembly 3 at the mounting groove 331 and the processing groove 22, thereby relaxing the elastic side 33 at this point to form a limit.
[0074] Similarly, when installing the magnet assembly 3, the elastic side 33 is first squeezed at the installation notch 21. During this process, the squeezing force received by the elastic side 33 can be partially released at the mating installation groove 331. The mating installation groove 331 is used to work in conjunction with the limiting plate 2 to avoid excessive squeezing affecting the recovery and release function of the elastic side 33.
[0075] After the elastic side 33 is installed in place, one end of the mounting groove 331 is close to the disassembly post 32, and the other end extends to the machining groove 22. This structure helps to guide the elastic side 33 to deform correctly during the installation process, so that it is better confined in the machining groove 22. It may also provide a certain elastic recovery guide during disassembly, making it easier to remove the magnet assembly 3.
[0076] Please see Figure 3 In some possible embodiments, the adsorption magnet 31 includes multiple adsorption layers spaced apart vertically, with the elastic side 33 connected to each of the multiple adsorption layers; a through gap 311 suitable for oil flow is left between each two adjacent adsorption layers. By setting multiple adsorption layers and through gaps 311, the adsorption effect of the magnet assembly 3 can be guaranteed.
[0077] On the one hand, the adsorption magnet 31 includes multiple adsorption layers spaced apart vertically, with a through gap 311 between each two adjacent adsorption layers to facilitate oil flow. This structure increases the adsorption area of the adsorption magnet 31, and the multi-layer structure can adsorb iron filings from different layers, thus improving the adsorption effect.
[0078] On the other hand, the through gap 311 allows the oil to flow between adjacent adsorption layers, ensuring the normal flow of the oil and preventing the oil circulation from being affected by the adsorption layer setting, which helps maintain the normal operation of the oil system in the transmission.
[0079] Preferably, the adsorption layer has three layers, which are spaced apart vertically; this avoids the problem of too few layers affecting the contact area between the adsorption magnet 31 and the oil, while also avoiding the problem of too many layers affecting the ease of disassembly and assembly of the magnet assembly 3.
[0080] Please see Figure 3 In some embodiments, each adsorption layer is a grid structure, and in the vertical direction, the horizontal and vertical grids of the grid structure are partially staggered.
[0081] By setting the adsorption layer as a grid structure, the adsorption effect of the adsorption magnet 31 is further improved. Specifically, the grid structure can increase the surface area of the adsorption layer, improve the adsorption efficiency, and may also facilitate better flow of oil around the adsorption layer, further enhancing the contact and adsorption effect between the adsorption magnet 31 and the iron filings in the oil.
[0082] To achieve the above-mentioned staggered distribution, optionally, in the vertical direction, the horizontal grid bars of the grid structure protrude upward beyond the top of the vertical grid bars of the grid structure, and the vertical grid bars of the grid structure protrude downward beyond the bottom of the horizontal grid bars of the grid structure.
[0083] Optionally, in the vertical direction, the longitudinal bars of the grid structure protrude upward beyond the top of the transverse bars of the grid structure, and the transverse bars of the grid structure protrude downward beyond the bottom of the longitudinal bars of the grid structure.
[0084] Preferably, the transverse and longitudinal grid strips are at the same height, and the transverse grid strips are slightly lower or slightly higher than the longitudinal grid strips by 0.2 mm. This height makes it easier to intercept iron filings in the oil.
[0085] For example, the shape of the adsorption magnet 31 can be designed as trapezoidal or dovetail, in addition to the traditional rectangular shape. Trapezoidal or dovetail-shaped adsorption magnets 31 can better maintain stability and reduce shaking when subjected to oil impact. Specifically, the upper base dimension of the trapezoidal adsorption magnet 31 is slightly smaller than the bottom dimension of the limiting groove 14, and the lower base dimension is slightly larger than the opening dimension of the limiting groove 14.
[0086] Please see Figure 3 For example, the disassembly column 32 is an elastic column, and the disassembly column 32 and the elastic side 33 are an integral injection-molded structure.
[0087] By setting the disassembly post 32 as an elastic post, it is easy for the disassembly post 32 to be locked and limited with the installation slot 21, thus ensuring the stability and reliability of the connection of the disassembly post 32.
[0088] The disassembly post 32 and the elastic retaining edge are integrally injection molded and made of the same type of elastic plastic. Preferably, the disassembly post 32 is positioned close to the mating mounting groove 331, facilitating the release of the extrusion deformation force of the elastic edge 33 and the disassembly post 32 at the mating mounting groove 331. Furthermore, the integral injection molding structure of the disassembly post 32 and the elastic edge 33 ensures the connection strength and integrity between them, reducing the risk of loosening or failure due to loose connections and improving the reliability of the magnet assembly 3.
[0089] The disassembly post 32 is set as an elastic post. During the installation process, the elastic post can more easily enter the installation notch 21 for positioning and undergo elastic deformation when reaching the bottom of the notch, so that the magnet assembly 3 is firmly clamped in the positioning groove 14.
[0090] Specifically, the elastic side 33 can be injection molded from PA66 material or other elastic plastics, and the specific material can be selectively set according to actual needs.
[0091] Optionally, the surface of the disassembly post 32 may be provided with an anti-slip texture. The anti-slip texture increases the friction between the fingers and the disassembly post 32, making it easier for operators to hold the post 32 firmly when disassembling the magnet assembly 3, preventing fingers from slipping. For example, a knurling process can be used to create a diamond or circular anti-slip texture on the surface of the disassembly post 32. The depth and spacing of the texture are optimized to ensure sufficient friction without affecting the sliding of the disassembly post 32 within the mounting notch 21.
[0092] Furthermore, to facilitate the removal of the disassembly column 32, the disassembly column 32 can be made to pass through the installation notch 21 and extend to the outside of the limiting plate 2, so as to facilitate the operator to apply force.
[0093] When the mounting housing 1 is disassembled and the iron filings captured on the magnet 31 need to be cleaned, the magnet assembly 3 needs to be removed. Specifically, the two disassembly posts 32 can be pressed with fingers. At this time, the nearby injection-molded elastic edge 33 is compressed, and the mounting groove 331 moves towards the root of the limiting plate 2 as the elastic edge is compressed. After most of the mounting groove 331 has moved inward into the processing groove 22, the two disassembly posts 32 can be pinched with fingers and pulled outward. At this time, the magnet 31 can be easily removed.
[0094] It should be noted that the mounting housing 1 is the main part of the transmission, and its mounting space contains internal components such as the gear system. The mounting housing 1 and the enclosed housing also serve a sealing function to prevent leakage of internal transmission fluid. In this design, the magnet assembly 3 is installed at the bottom of the mounting housing 1, where the fluid accumulates. A limiting groove 14 is designed here to limit and protect the magnet assembly 3.
[0095] This application, through targeted design of the magnet assembly 3 and the mounting housing 1, enables the adsorption magnet 31 to achieve both anti-detachment and detachable functions, while also achieving a large-area and wide-range adsorption function for iron filings, thus greatly improving the overall function of the transmission.
[0096] Based on the same inventive concept, this application also provides a transmission, characterized in that it includes the above-described transmission magnet mounting structure.
[0097] The transmission provided in this application, by employing the aforementioned transmission magnet mounting structure, possesses all the beneficial effects of such a structure. It improves the connection stability and reliability of the magnet mounting structure while ensuring the adsorption effect of the magnet 31, and enhances the ease of assembly and disassembly of the magnet assembly 3. This transmission avoids problems such as iron filings accumulating in the oil, affecting the oil pump's performance, causing abnormal noise, and causing wear on gear pairs and bearings, thereby improving the overall performance and service life of the transmission.
[0098] Based on the same inventive concept, embodiments of this application also provide a vehicle including the aforementioned transmission.
[0099] The vehicle provided in this application, having the aforementioned transmission, possesses all the beneficial effects of that transmission. The stable connection of the magnet 31 mounting structure and the presence of a bottom oil passage ensure the effective adsorption of the magnet 31, extending the transmission's service life. Furthermore, the magnet 31 within the transmission is easily disassembled and reassembled, offering high convenience. This means that during vehicle operation, the transmission can effectively adsorb iron filings, reducing damage to the vehicle's transmission system, ensuring normal vehicle operation, and improving the vehicle's reliability and durability.
[0100] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
