Description

Technical Field

[0001] The present invention relates to the technical field of engine lubricating oil distribution, in particular to a shaft oil-swing distribution assembly and a shaft oil-swing distribution device having the same. Background Art

[0002] In oil-cooled electric and hybrid systems, most components are lubricated using active lubrication, allowing the lubricant to flow directly from the oil pump to the lubricated components. The lubrication flow rate can be adjusted by controlling the pump's speed. However, if the system requires lubrication within the rotating shaft, and multiple components within the shaft require lubrication, the distribution of lubricant within the shaft varies with the speed. At higher speeds, centrifugal force influences the oil rejection rate at outlets closer to the oil inlet, increasing the amount of oil thrown away. Meanwhile, outlets farther from the oil inlet experience less oil rejection, or even no oil at all. This leads to extremely severe uneven distribution, impairing the reliability of under-lubricated components and making them more susceptible to reliability issues such as excessive wear and erosion.

[0003] Currently, no effective solutions have been proposed for the above technical problems. Summary of the Invention

When the fixing assembly is connected to the oil outlet hole, the second annular protrusion is arranged in a fit fit with the side wall of the oil outlet hole, and at least a partial active cavity is formed between the second annular protrusion, the annular base, and the first annular protrusion.

[0008] Furthermore, a first limiting structure is provided at one end of the first annular protrusion away from the annular base, and the sliding assembly has an extreme position. When the sliding assembly moves to the extreme position along the axial direction of the oil outlet, the sliding assembly is cooperatively connected with the first limiting structure.

[0009] Furthermore, the first limiting structure includes a stop protrusion protruding in the radial direction of the first annular protrusion. When the sliding assembly is in the extreme position, the side of the stop protrusion facing the annular base abuts against at least part of the sliding assembly.

[0010] Furthermore, the distance between the end of the first annular protrusion away from the annular base and the oil outlet end of the oil outlet hole is smaller than the distance between the oil inlet end and the oil outlet end of the oil outlet hole.

[0011] Furthermore, the sliding assembly includes a movable fitting section and an oil-blocking section, wherein the oil-blocking section is arranged near the oil inlet side of the oil outlet hole, and a second limiting structure is provided at the connection position between the movable fitting section and the oil-blocking section. When the sliding assembly is in the extreme position, at least part of the oil-blocking section extends outside the oil outlet hole, and the second limiting structure is connected in cooperation with the first limiting structure to perform axial limiting on the sliding assembly.

[0012] Furthermore, the second limiting structure includes a limiting step, and the limiting step is arranged toward the side where the first annular protrusion is located.

[0014] Furthermore, the sliding assembly has an initial position.

[0042] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0043] Combine Figures 1 to 4 As shown, according to a specific embodiment of the present application, a shaft oil-swinging distribution assembly is provided.

[0044] Specifically, if Figures 1 to 4 As shown, the shaft oil-spinning distribution assembly includes a fixed assembly 20 and a sliding assembly 30. The fixed assembly 20 is used to connect with the oil outlet hole 11 of the shaft 10. When the fixed assembly 20 is connected to the oil outlet hole 11, part of the fixed assembly 20 extends into the oil outlet hole 11, and the other part of the fixed assembly 20 is arranged on the oil outlet side of the oil outlet hole 11, so that an active cavity 200 with one end closed is formed between the fixed assembly 20 and the side wall of the oil outlet hole 11. The active cavity 200 is connected to the oil inlet side of the oil outlet hole 11; the sliding assembly 30 is arranged on the active cavity 200. The sliding assembly 30 is in the cavity 200, and the fixed assembly 20 is slidably connected along the axial direction of the oil outlet hole 11, and an adjusting oil circuit is formed between the sliding assembly 30 and the cavity wall of the movable cavity 200; wherein, when the oil pressure in the adjusting oil circuit reaches a preset pressure value, the oil in the adjusting oil circuit can push the sliding assembly 30 to move in a direction away from the oil outlet side of the oil outlet hole 11, so that at least part of the sliding assembly 30 extends to the oil inlet side of the oil outlet hole 11, so as to block the oil from flowing along the oil inlet side of the oil outlet hole 11 to the oil outlet side of the oil outlet hole 11.

[0045] By applying the technical solution of this embodiment, the shaft oil-swinging distribution component is fixed to the oil outlet hole 11 through the fixing component 20, and part of the fixing component 20 extends into the oil outlet hole 11 to increase the contact area between the fixing component 20 and the oil outlet hole 11, thereby improving the stability of the connection between the distribution component and the oil outlet hole 11. The other part of the fixing component 20 is arranged on the oil outlet side of the oil outlet hole 11, so that an active cavity 200 is formed between the fixing component 20 and the side wall of the oil outlet hole 11. The active cavity 200 is connected to the oil inlet side of the oil outlet hole 11, so that the lubricating oil can enter the active cavity 200 when passing through the oil outlet hole 11. The sliding component 30 is arranged in the active cavity 200, and the sliding component 30 and the cavity wall of the active cavity 200 form a movable cavity 200. The regulating oil circuit is regulated by the amount and pressure of the lubricating oil. As the rotation speed of the rotating shaft 10 increases, the centrifugal force on the lubricating oil increases, and the oil pressure of the lubricating oil entering the regulating oil circuit of the active chamber 200 also increases. When the lubricating oil pressure in the regulating oil circuit reaches the preset pressure for pushing the sliding component 30 to move, the oil circuit can be regulated, and the sliding component 30 is pressed to move in the direction of the oil outlet side away from the oil outlet hole 11. The sliding component 30 is pressed and extended to the lubricating oil flow end on the oil inlet side, blocking the lubricating oil flowing along the side wall of the oil inlet side, thereby reducing the amount of lubricating oil entering the active chamber 200 along the side wall of the oil inlet side, and effectively reducing the oil output of the oil outlet hole 11 that is closer to the oil inlet side.

[0046] It should be noted that the movable distance of the sliding assembly 30 on the cavity wall of the movable cavity 200 can be set to different movable distances according to the different distances between the oil outlet 11 and the oil inlet side, that is, the shaft oil-swinging distribution assembly can be designed to have different degrees of blocking of the lubricating oil. When the oil outlet 11 farther away from the oil inlet side of the shaft 10 itself has an insufficient oil output to reach the preset oil pressure of the regulating oil circuit, the oil outlet 11 may not be provided with a distribution assembly.

[0047] In this embodiment, if Figure 2 As shown, an oil drain chamber 40 is further formed on the side wall of the other end of the sliding component 30 and the fixed component 20. When the lubricating oil enters the oil outlet hole 11, it can enter the movable chamber 200 and the oil drain chamber 40 at the same time. As the lubricating oil continues to enter the movable chamber 200 and the oil drain chamber 40, and under the action of centrifugal force, the lubricating oil in the movable chamber 200 and the oil drain chamber 40 forms a certain oil pressure. When the difference between the oil pressure acting in the movable chamber 200 and the oil pressure acting in the oil drain chamber 40 reaches a value greater than the centrifugal force of the sliding component 30 itself (that is, when the preset pressure value is reached), the sliding component 30 moves and extends into the rotating shaft 10 to block the lubricating oil.

[0048] In another embodiment of the present application, the shaft oil-spinning distribution assembly is arranged on the oil outlet hole 11 of the oil pump shaft, and the distribution of the lubricating oil can be automatically adjusted according to the rotation speed of the shaft 10, effectively avoiding excessive throwing out of the lubricating oil during high-speed rotation, while ensuring the necessary lubricating oil output during low-speed rotation. It can be applied to various engines that require precise oil distribution, improves the operating efficiency and stability of the equipment, significantly reduces mechanical wear and overheating caused by improper lubricating oil distribution, and extends the service life of the equipment.

[0049] Specifically, if Figure 2 、 Figure 4 As shown, the fixing assembly 20 includes an annular base 21, one end of which is provided with a first annular protrusion 22 extending in the axial direction of the annular base 21. When the fixing assembly 20 is connected to the oil outlet hole 11, the first annular protrusion 22 extends into the oil outlet hole 11, forming a movable cavity 200 between the annular base 21, the oil outlet hole 11, and the first annular protrusion 22. The first annular protrusion 22 is arranged at a distance from the side wall of the oil outlet hole 11 to form the movable cavity 200 between the annular base 21, the oil outlet hole 11, and the first annular protrusion 22. This arrangement facilitates the installation of the shaft oil-spinning distribution assembly and ensures the stability of the connection between the distribution assembly and the rotating shaft 10.

[0050] Furthermore, if Figure 2 、 Figure 4 As shown, the fixing assembly 20 further includes a second annular protrusion 23, which is spaced radially from the first annular protrusion 22 along the annular base 21. When the fixing assembly 20 is connected to the oil outlet 11, the second annular protrusion 23 is positioned in close contact with the sidewall of the oil outlet 11, and at least a portion of the active cavity 200 is formed between the second annular protrusion 23, the annular base 21, and the first annular protrusion 22. The second annular protrusion 23 extends axially along the oil outlet 11 and is positioned in close contact with the wall of the oil outlet 11, further enhancing the stability and reliability of the connection between the distribution assembly and the oil outlet 11. This ensures even distribution of lubricating oil during high-speed rotation, effectively preventing equipment imbalance and vibration issues caused by uneven oil distribution.

[0051] It should be noted that, in this embodiment, the second annular protrusion 23 is connected to the side wall of the oil outlet hole 11 by an interference fit connection, so that the connection between the fixing component 20 and the oil outlet hole 11 is stable. The extension length of the second annular protrusion 23 can be adjusted according to actual needs, or the second annular protrusion 23 can be eliminated, and the oil outlet hole 11 can be directly connected to the annular base 21.

[0052] Furthermore, a first limiting structure 24 is provided at one end of the first annular protrusion 22, distal from the annular base 21. The sliding assembly 30 has a limit position. When the sliding assembly 30 moves axially along the oil outlet 11 to the limit position, the sliding assembly 30 engages with the first limiting structure 24. The provision of the first limiting structure 24 limits the range of motion of the sliding assembly 30, effectively preventing excessive movement of the sliding assembly 30, resulting in separation from the fixed assembly 20 or damage due to excessive oil pressure in the regulating oil circuit. This ensures the safe operation of the distribution assembly and reduces maintenance costs.

[0053] It should be noted that the limit position of the sliding assembly 30 is the maximum distance that the sliding assembly 30 extends axially toward the rotating shaft 10, that is, the maximum oil output that the distribution assembly can control and reduce. The limit position of the sliding assembly 30 of different distribution assemblies can be set to different positions to adapt to the different setting positions of the oil outlet hole 11 on the rotating shaft 10.

[0054] Specifically, the first limiting structure 24 includes a stop protrusion 240 protruding in the radial direction of the first annular protrusion 22. When the sliding assembly 30 is in the extreme position, the side of the stop protrusion 240 facing the annular base 21 abuts against at least a portion of the sliding assembly 30. By abutting against the sliding assembly 30, the stop protrusion 240 limits the continued movement of the sliding assembly 30. In other words, the provision of the stop protrusion 240 further refines the motion control of the sliding assembly 30, thereby ensuring the proper distribution of lubricating oil at different speeds and improving the performance and efficiency of the equipment.

[0055] It should be noted that the first limiting structure 24 can also be an elastic member arranged on the first annular protrusion 22 or the annular base 21, and the elastic member is connected to the sliding assembly 30. When the elastic member is in a natural state, the sliding assembly 30 is located in the initial position in the adjustment oil circuit. When the oil pressure reaches the preset pressure, the sliding assembly 30 can be pushed to move. The limit position of the sliding assembly 30 is the limit size of the elastic member that can be stretched. At the same time, when the speed of the rotating shaft 10 is reduced to a stop, the sliding assembly 30 can rely on the restoring force of the elastic member to reset to the initial position, and can also achieve the effect of automatically adjusting the oil output of the oil outlet 11.

[0056] Furthermore, the distance between the end of the first annular protrusion 22 away from the annular base 21 and the oil outlet end of the oil outlet hole 11 is smaller than the distance between the oil inlet end of the oil outlet hole 11 and the oil outlet end of the oil outlet hole 11. This allows the lubricating oil to push the sliding assembly 30 to move more quickly when the preset pressure value is reached in the regulating oil circuit, and timely adjusts and feedbacks the amount of oil entering the oil outlet hole 11 and the amount of oil discharged from the oil outlet hole 11, thereby improving the response speed of the lubricating oil distribution to the oil outlet hole 11. It is applicable to equipment that requires rapid response, improves the operating efficiency and processing accuracy of the equipment, and enables the rotating shaft 10 to timely and accurately lubricate the corresponding components when running at high speed, avoiding wear and precision reduction of parts caused by insufficient lubrication, and improving work efficiency and work quality.

[0057] Furthermore, the sliding assembly 30 includes a movable fitting section 31 and an oil-blocking section 32, wherein the oil-blocking section 32 is arranged near the oil inlet side of the oil outlet hole 11, and a second limiting structure 33 is provided at the connection position between the movable fitting section 31 and the oil-blocking section 32. When the sliding assembly 30 is in the extreme position, at least part of the oil-blocking section 32 extends outside the oil outlet hole 11, and the second limiting structure 33 is connected in cooperation with the first limiting structure 24 to axially limit the sliding assembly 30. The provision of the second limiting structure 33 can further ensure the stability of the sliding assembly 30 in the extreme position, prevent the sliding assembly 30 from being damaged due to excessive sliding, and prevent the lubricating oil from being excessively thrown out of the oil outlet hole 11 under high-speed rotation. The second limiting structure 33 is used in conjunction with the first limiting structure 24 to further ensure the movement accuracy of the sliding assembly 30, optimize the contact between the sliding assembly 30 and the first annular protrusion 22, and avoid damage caused by the collision between the first annular protrusion 22 and the sliding assembly 30.

[0058] Specifically, the second limiting structure 33 includes a limiting step 330, which is arranged toward the side where the first annular protrusion 22 is located. Arranging the second limiting structure 33 so that the limiting step 330 cooperates with the stop protrusion 240 of the first limiting structure 24 simplifies the manufacturing process of the sliding assembly 30 and the first annular protrusion 22, reducing manufacturing costs and time.

[0059] Furthermore, if Figure 2 As shown, a driving bevel 310 is provided on the end of the movable engagement section 31 proximal to the annular base 21. The distance between the driving bevel 310 and the annular base 21 gradually increases as the distance moves away from the axial centerline of the annular base 21. The provision of the driving bevel 310 increases the contact area between the lubricating oil in the regulating oil circuit and the sliding assembly 30, allowing the oil pressure in the regulating circuit to better act on the sliding assembly 30 and improving the efficiency of lubricating oil distribution.

[0060] It should be noted that the slope of the driving ramp 310 can be adjusted to adjust the pressure and direction of the lubricating oil acting on the sliding component 30, thereby adjusting the size of the preset oil pressure value that causes the sliding component 30 to slide. For example, when the slope is 0, the driving ramp 310 is in contact with the annular base 21. In this case, no lubricating oil enters between the driving ramp 310 and the annular base 21, and no pressure in the preset moving direction can be applied to the sliding component 30. Therefore, appropriately setting the slope of the driving ramp 310 can adjust the flexibility and response rate of the movement of the sliding component 30.

[0061] Furthermore, the sliding assembly 30 has an initial position. When the sliding assembly 30 is in the initial position, the end of the oil-blocking section 32 near the oil inlet side is flush with the end of the oil outlet hole 11 near the axial centerline of the rotating shaft 10, and the end of the movable fitting section 31 near the annular base 21 abuts the annular base 21. When the sliding assembly 30 is in the initial position, the oil-blocking section 32 is flush with the end of the oil outlet hole 11 near the axial centerline of the rotating shaft 10, which does not affect the oil output of the oil outlet hole 11 farther from the oil inlet side. This allows the rotating shaft 10 to be adequately lubricated through the oil outlet hole 11 when rotating at low speed, thereby preventing wear during startup or low-speed operation of the equipment.

[0062] According to another specific embodiment of the present application, a shaft oil-swing distribution device is also provided, which includes multiple shaft oil-swing distribution components. The shaft oil-swing distribution component is the shaft oil-swing distribution component in the above embodiment. The distance between the initial position of the sliding component 30 and the extreme position of the sliding component 30 is the active distance of the shaft oil-swing distribution component, and the active distances of each shaft oil-swing distribution component are set differently.

[0063] By applying the technical solution of this embodiment, distribution components can be set at the oil outlet hole 11 with the largest oil output close to the oil inlet side and the oil outlet hole 11 with a larger oil output. According to the different oil outputs of each oil outlet hole 11, the movable distances of the distribution components set at each oil outlet hole 11 are also set differently, that is, the sizes of the oil discharge chamber 40 of each oil outlet hole 11 are set differently. In this way, the oil output of the oil outlet holes 11 at different distances from the oil inlet side can be evenly distributed, which can effectively solve the problem of uneven oil distribution of each oil outlet hole 11 in the rotating shaft 10 due to the action of centrifugal force.

[0064] The present application also provides a preferred embodiment of a shaft oil-splitting distribution assembly, which utilizes the centrifugal force of the lubricating oil to achieve the purpose of uniform distribution of the lubricating oil in each oil outlet 11 in the shaft 10 without the need for active control. It is not only highly reliable but also simple in structure and low in cost.

[0065] Specifically, the shaft oil-spinning and distribution assembly is mainly composed of a fixed assembly 20 and a sliding assembly 30, such as Figures 1 to 4As shown, the oil outlet hole 11 closer to the oil inlet side is provided with a fixing component 20. The oil outlet hole 11 needs to be expanded to facilitate the installation of the fixing component 20. The fixing component 20 and the oil outlet hole 11 are connected by interference fit to prevent the fixing component 20 from loosening or falling out due to centrifugal force. The sliding component 30 is installed on the fixing component 20. The sliding component 30 needs to use a material with low density, light weight and elastic deformation to facilitate the smooth installation of the sliding component 30 on the fixing component 20, ensuring that the sliding component 30 can be pushed by the lubricating oil and overcome its own centrifugal force and the pressure of the oil discharge chamber 40 to move toward the axial direction of the rotating shaft 10.

[0066] When the lubricating oil enters the inside of the rotating shaft 10 from the oil inlet side, due to the rotation of the rotating shaft 10, the lubricating oil will flow along the inner wall of the rotating shaft 10. If the rotating shaft oil-swinging distribution component is not installed, the lubricating oil will first flow out from the oil outlet hole 11 closer to the oil inlet side, and as the rotation speed of the rotating shaft 10 increases, the amount of lubricating oil flowing out of the oil outlet hole 11 becomes larger and larger. After the rotating shaft oil-swinging distribution component is installed, the lubricating oil can flow into the active cavity 200 and the oil discharge cavity 40 of the distribution component while flowing out from the oil outlet hole 11. As the active cavity 200 and the oil discharge cavity 40 continue to enter the lubricating oil and are centrifuged, the lubricating oil will flow out of the oil outlet hole 11. Under the action of , a certain oil pressure is formed. When the difference between the force of the oil pressure acting on the upper end surface and the lower end surface of the sliding component 30 is greater than the centrifugal force of the sliding component 30 itself, the sliding component 30 will gradually move toward the axial center of the rotating shaft 10. The higher the speed of the rotating shaft 10, the greater the moving distance. When the sliding component 30 moves toward the axial center of the rotating shaft 10, the oil-blocking section 32 of the sliding component 30 can effectively prevent the lubricating oil from flowing out of the oil outlet 11. At this time, the lubricating oil can flow out more from other oil outlets 11, which can effectively solve the problem of uneven distribution of the oil outlets 11 in the rotating shaft 10 due to the action of centrifugal force.

[0067] According to another specific embodiment of the present application, an oil-cooled electric drive hybrid system is also provided. The oil-cooled electric drive and hybrid system includes a shaft oil-swinging distribution component. The shaft oil-swinging distribution component includes a fixed component 20 and a sliding component 30. The fixed component 20 is used to connect with the oil outlet hole 11 of the shaft 10. When the fixed component 20 is connected to the oil outlet hole 11, part of the fixed component 20 extends into the oil outlet hole 11, and the other part of the fixed component 20 is arranged on the oil outlet side of the oil outlet hole 11, so that an active cavity 200 with one end closed is formed between the fixed component 20 and the side wall of the oil outlet hole 11, and the active cavity 200 is connected to the oil outlet hole 11. 1; the sliding assembly 30 is arranged in the active chamber 200, and the sliding assembly 30 and the fixed assembly 20 are slidably connected along the axial direction of the oil outlet hole 11, and an adjusting oil circuit is formed between the sliding assembly 30 and the cavity wall of the active chamber 200; wherein, when the oil pressure in the adjusting oil circuit reaches a preset pressure value, the oil in the adjusting oil circuit can push the sliding assembly 30 to move in a direction away from the oil outlet side of the oil outlet hole 11, so that at least part of the sliding assembly 30 extends to the oil inlet side of the oil outlet hole 11, so as to prevent the oil from flowing along the oil inlet side of the oil outlet hole 11 to the oil outlet side of the oil outlet hole 11. In this embodiment, the shaft oil-swinging distribution component is fixed to the oil outlet hole 11 through the fixing component 20, and part of the fixing component 20 extends into the oil outlet hole 11 to increase the contact area between the fixing component 20 and the oil outlet hole 11, thereby improving the stability of the connection between the distribution component and the oil outlet hole 11. The other part of the fixing component 20 is arranged on the oil outlet side of the oil outlet hole 11, so that an active cavity 200 is formed between the fixing component 20 and the side wall of the oil outlet hole 11. The active cavity 200 is connected to the oil inlet side of the oil outlet hole 11, so that the lubricating oil can enter the active cavity 200 when passing through the oil outlet hole 11. The sliding component 30 is arranged in the active cavity 200, and the sliding component 30 and the cavity wall of the active cavity 200 form an adjustable oil path that can be adjusted by the amount and pressure of the lubricating oil. As the rotation speed of the shaft 10 increases, the lubricating oil level increases. As the centrifugal force on the lubricating oil increases, the oil pressure of the lubricating oil entering the active chamber 200 regulating oil circuit also increases. When the lubricating oil pressure in the regulating oil circuit reaches the preset pressure for pushing the sliding assembly 30 to move, the oil circuit can be adjusted, and the sliding assembly 30 is pressed to move in the direction of the oil outlet side away from the oil outlet hole 11. The sliding assembly 30 is pressed and slid to extend to the lubricating oil flow end on the oil inlet side, blocking the lubricating oil flowing along the side wall of the oil inlet side, which can reduce the amount of lubricating oil entering the active chamber 200 along the side wall of the oil inlet side, and effectively reduce the oil output of the oil outlet hole 11 close to the oil inlet side, thereby improving the uniformity of the lubricating oil distribution in the rotating shaft when the oil-cooled electric hybrid system has a lubrication demand in the rotating shaft, so that the components are adequately lubricated to avoid excessive wear, ablation and the like.
