[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] Reference below Figure 1-Figure 3 A housing 100 of a speed reducer according to an embodiment of the present invention is described. The housing 100 of the speed reducer can be applied to a speed reducer, and the speed reducer can be applied to a vehicle.

[0029] Combine Figure 1-Figure 3 As shown, the housing 100 of the reducer according to the present invention may mainly include: a housing body 10. The housing body 10 has an installation cavity formed therein, which not only provides a stable installation location and support for key components such as gears, shafts, and bearings, ensuring that these components can be accurately installed and function properly, but also acts as a seal to prevent external dust, moisture, and other contaminants from entering the installation cavity, while also preventing lubricating oil from leaking out of the installation cavity, helping to maintain good lubrication conditions and extending the service life of the reducer.

[0030] Furthermore, the housing body 10 is provided with a plurality of bearing mounting holes 101. These holes are suitable for mounting bearings, and the bearings and the bearing mounting holes 101 are sized and configured to ensure proper installation. These holes not only provide support and positioning for the bearings but also facilitate their installation and removal.

[0031] Furthermore, an oil storage tank 102 is provided on the inner wall of the shell body 10. The oil storage tank 102 is open to one side of the installation cavity and is connected to the installation cavity. The oil storage tank 102 is connected to a plurality of bearing mounting holes 101. Specifically, the oil storage tank 102 can store a certain amount of lubricating oil to ensure that the gears, bearings and other transmission components have sufficient lubricating oil for lubrication, so as to ensure the normal operation and efficient work of the gears, bearings and other transmission components. By opening the oil storage tank 102 to one side of the installation cavity and connecting it to the installation cavity, and connecting the oil storage tank 102 to a plurality of bearing mounting holes 101, not only can the lubricating oil in the installation cavity be collected by the oil storage tank 102, but the lubricating oil can also flow back to the oil storage tank 102 through the bearing mounting holes 101, so as to reduce the power loss of the gear stirring the oil and improve the overall efficiency of the electric drive axle, thereby reducing the amount of oil filling, improving the oil utilization rate, and saving the user's maintenance costs.

[0032] It should be noted that the present invention adopts splash lubrication.

[0033] Furthermore, a filtering device 103 is provided in the oil storage tank 102, so that the reflux oil can be adsorbed and filtered to improve the cleanliness of the reflux oil, thereby preventing impurities and debris carried in the oil from splashing again and causing damage to the components in the installation cavity, thereby improving the life of the gear shaft system.

[0034] With this arrangement, when the reducer is operating, the high-speed rotating gears will pick up the lubricating oil from the oil reservoir 102 and fling the oil around through centrifugal force. At the same time, the lubricating oil contacts the gear tooth surfaces, which can reduce the friction and wear generated at the gears and remove the heat generated by friction. The lubricating oil is carried to the bearing position or the inner wall of the mounting cavity through the gears or other rotating parts, thereby reducing the friction and wear generated at the bearings and removing the heat generated by friction. The splashed lubricating oil will flow downward along the inner wall of the mounting cavity and the inner wall of the bearing mounting hole 101, and eventually return to the oil reservoir 102. At the same time, the oil returning to the oil reservoir 102 is filtered to ensure the cleanliness of the oil in the oil reservoir 102 during circulation. The design of the oil reservoir 102 can ensure good lubrication of the bearings and gears, solve the problem of insufficient lubrication of the bearings under low-speed and climbing conditions, and achieve sufficient lubrication under different vehicle operating conditions.

[0035] Therefore, by arranging an oil storage tank 102 on the inner wall of the shell body 10, the oil storage tank 102 is opened toward one side of the installation cavity and is connected with the installation cavity, the oil storage tank 102 is connected with multiple bearing mounting holes 101, and a filtering device 103 is provided in the oil storage tank 102. This can not only reduce the loss and filling amount of oil and improve the utilization rate of oil, but also improve the cleanliness of oil, improve lubrication efficiency, and improve system reliability, and can achieve sufficient lubrication in different working conditions such as driving and reversing, and meet the full working conditions of the whole vehicle.

[0036] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the filter device 103 includes at least one of a magnet, a filter element, a filter screen, and an oil filter pump. Specifically, the magnet can absorb iron or magnetic metal particles in the lubricating oil, the filter element can effectively remove solid impurities in the lubricating oil, the filter screen can intercept larger impurities and particulate matter, and the oil filter pump can select different filtration precisions. By using at least one of the magnet, filter element, filter screen, and oil filter pump as the filter device 103, impurities in the oil can be removed, and the cleanliness of the oil in the oil storage tank 102 can be improved to prevent the impurities and debris carried by the oil from splashing again and causing damage to the components in the installation cavity. This can improve the reliability of the reducer structure, improve the operating efficiency of the reducer, and extend the service life of the reducer.

[0037] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the filter device 103 is magnetically adsorbed and disposed in the oil storage tank 102; and / or the filter device 103 is screwed and fixed to the oil storage tank 102; and / or the filter device 103 is interference fit with the oil storage tank 102.

[0038] Specifically, different filtering devices 103 are suitable for different installation methods. For example, a magnet can be magnetically adsorbed and set in the oil storage tank 102; the filter element can be installed by interference fit with the oil storage tank 102; the filter screen can be fixed by means of snaps, bolts or pressure plates; the oil filter pump can be fixed by screw connection, and the inlet and outlet pipes of the oil filter pump must be correctly connected; the filtering device 103 is installed using an applicable installation method, which can improve the stability and reliability of the installation of the filtering device 103 and ensure a good filtering effect of the filtering device 103.

[0039] Combine Figure 1 、 Figure 2 and Figure 3As shown, the inner wall of the housing body 10 is provided with a plurality of oil-guiding ribs 104, and the oil reservoir 102 is spaced apart on one radial side of the bearing mounting hole 101. The plurality of oil-guiding ribs 104 and the oil reservoir 102 are located on the same radial side of the bearing mounting hole 101. The plurality of oil-guiding ribs 104 and the oil reservoir 102 are spaced apart and correspondingly connected to guide the oil on the inner wall of the housing body 10 to the oil reservoir 102. This facilitates the flow of oil between the oil reservoir 102 and the oil-guiding ribs 104, and can guide oil splashed onto the inner wall of the mounting cavity back into the oil reservoir 102, thereby improving the efficiency and utilization of the oil and helping to ensure good lubrication of the bearing.

[0040] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the inner wall of the housing body 10 is further provided with a plurality of reverse oil return slopes 105. The oil storage tank 102 and the plurality of reverse oil return slopes 105 are respectively located on radial sides of the bearing mounting hole 101. The plurality of reverse oil return slopes 105 are spaced apart from and correspondingly communicate with the bearing mounting hole 101 to guide the oil on the inner wall of the housing body 10 to the bearing mounting hole 101. Specifically, by providing the plurality of reverse oil return slopes 105 and ensuring that the plurality of reverse oil return slopes 105 are spaced apart from and correspondingly communicate with the bearing mounting hole 101, the oil can be guided to the bearing mounting hole 101 through the reverse oil return slopes 105 when the vehicle is reversing, thereby ensuring sufficient lubrication of the bearings when the vehicle is reversing, improving the lubrication effect of the lubrication system in the reducer, and improving the reliability of the reducer structure.

[0041] Furthermore, multiple oil guide ribs 104 and the oil storage groove 102 are located on the same radial side of the bearing mounting hole 101, and multiple reversing oil return slopes 105 and the oil storage groove 102 are respectively located on the radial sides of the bearing mounting hole 101. This not only can effectively distinguish the oil guide ribs 104 and the reversing oil return slope 105, simplify the structure of the outer shell body 10, but also can improve the stability and rationality of the structure of the outer shell body 10, and can prevent the oil guide ribs 104 and the reversing oil return slope 105 from affecting each other, which helps to ensure good lubrication effect under different working conditions of the vehicle.

[0042] Combine Figure 1 、 Figure 2 and Figure 3As shown, the shell body 10 includes a main shell 106 and an end cover 107. The end cover 107 is covered on one side of the main shell 106. A plurality of bearing mounting holes 101 are provided on the end cover 107 and the main shell 106. The plurality of bearing mounting holes 101 on the end cover 107 correspond one to one with the plurality of bearing mounting holes 101 on the main shell 106. A first main oil channel 1071 is provided in the end cover 107, and the first main oil channel 1071 is connected to the bearing mounting holes 101 on the end cover 107. A second main oil channel 1061 is provided in the main shell 106, and the second main oil channel 1061 is connected to the bearing mounting holes 101 on the main shell 106. The first main oil channel 1071 and the second main oil channel 1061 are connected to each other.

[0043] Specifically, the end cover 107 is installed on one side of the main shell 106 so that the main shell 106 and the end cover 107 fit tightly together to form a relatively sealed space. This not only prevents the lubricating oil in the outer shell body 10 from flowing out to ensure the normal lubrication environment of the reducer, but also prevents external dust, moisture and impurities from entering the reducer to contaminate the lubricating oil or aggravate the wear of components such as gears and bearings.

[0044] Furthermore, a plurality of bearing mounting holes 101 are provided on both the end cover 107 and the main shell 106, and the plurality of bearing mounting holes 101 on the end cover 107 correspond one to one with the plurality of bearing mounting holes 101 on the main shell 106. This not only provides an installation position for the bearing, realizes rapid positioning of the bearing, and facilitates the installation and removal of the bearing, but also ensures the accuracy of the bearing installation, thereby improving the reliability and accuracy of the structure of the shell body 10.

[0045] Furthermore, a first main oil passage 1071 is provided in the end cover 107, and the first main oil passage 1071 is communicated with the bearing mounting hole 101 on the end cover 107. A second main oil passage 1061 is provided in the main housing 106, and the second main oil passage 1061 is communicated with the bearing mounting hole 101 on the main housing 106. The first main oil passage 1071 and the second main oil passage 1061 are communicated with each other, and the first main oil passage 1071 and the bearing mounting hole 101 on the end cover 107 are also communicated with the oil storage tank 102. The second main oil channel 1061 realizes the connection between the oil storage tank 102 and the bearing mounting hole 101 on the main shell 106, thereby realizing the oil transmission between the bearing mounting hole 101 on the end cover 107 and the main shell 106 and the oil storage tank 102, which can facilitate the oil at the bearing mounting hole 101 to flow back to the oil storage tank 102, improve the utilization rate of the oil, and ensure sufficient lubrication of the bearings. It can also take away the heat flowing through the high-temperature components while the oil flows, prevent local overheating inside the reducer, and help maintain the normal operation of the reducer.

[0046] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the reducer housing 100 further includes an oil gallery pin 20, which is disposed between the end cover 107 and the main housing 106. The end cover 107 and the main housing 106 are respectively connected to the oil gallery pin 20, and the two ends of the oil gallery pin 20 are respectively connected to the first main oil gallery 1071 and the second main oil gallery 1061. Specifically, the oil gallery pin 20 not only serves as a guide but also as a seal. By disposing the oil gallery pin 20 between the end cover 107 and the main housing 106, the end cover 107 and the main housing 106 are respectively connected to the oil gallery pin 20. This not only prevents oil leakage from the gap between the end cover 107 and the main housing 106, thereby improving the sealing effect of the reducer housing 100, but also ensures a good oil flow effect between the end cover 107 and the main housing 106, which helps to improve the structural reliability of the reducer housing 100, improve the lubrication efficiency of the lubricating oil in the reducer structure, and extend the service life of the entire reducer system.

[0047] Furthermore, the two ends of the oil channel pin 20 are respectively connected to the first main oil channel 1071 and the second main oil channel 1061, which can improve the reliability of the connecting structure between the first main oil channel 1071 and the second main oil channel 1061 and ensure the normal flow of oil between the first main oil channel 1071 and the second main oil channel 1061.

[0048] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the oil gallery pin 20 includes at least one of a hollow metal pin, a hollow nylon pin, and an O-ring. Specifically, by including at least one of the hollow metal pin, the hollow nylon pin, and the O-ring, the oil gallery pin 20 can achieve good sealing and flow guidance, improve the structural reliability of the oil gallery pin 20, and enhance the lubrication efficiency and utilization rate of the lubricating oil.

[0049] In some embodiments of the present invention, the main housing 106 , the oil channel pin 20 , and the end cover 107 together constitute the entire lubrication system. The bearings on the main housing 106 and the end cover 107 can be distributed with oil in equal proportions for full lubrication.

[0050] In some embodiments of the present invention, when the vehicle is running normally and the reducer is working normally, the high-speed rotating gears will pick up the lubricating oil from the oil storage tank 102 and throw the oil to the surroundings through centrifugal force. At the same time, the lubricating oil contacts the gear tooth surface, which can reduce the friction and wear generated at the gear and take away the heat generated by friction; the lubricating oil is brought to the bearing position or the inner wall of the mounting cavity through the gears or other rotating parts, and the oil on the inner wall of the mounting cavity flows to the oil guide ribs 104, and the oil guide ribs 104 then guide the oil to flow to the bearing mounting hole 101, so that the oil splashed and drained to the bearing mounting hole 101 work together to reduce the friction and wear generated at the bearing and take away the heat generated by friction; the oil at the bearing mounting hole 101 is finally returned to the oil storage tank 102 through the first main oil channel 1071 and the second main oil channel 1061.

[0051] The reducer according to the present invention may mainly include: the reducer housing 100 described above. Specifically, since the reducer housing 100 has a more reliable structure and good working performance, the reducer housing 100 applied to the reducer can improve the utilization rate and lubrication effect of the lubricating oil in the reducer, and can ensure sufficient lubrication of components such as gears and bearings in the reducer.

[0052] The vehicle according to the present invention may primarily include the aforementioned speed reducer. Specifically, due to its more reliable structure and excellent operating performance, its application in a vehicle not only reduces vehicle maintenance costs but also ensures adequate lubrication under various operating conditions, thereby ensuring smooth vehicle operation and enhancing the driving experience for passengers.
