Description

Lubrication system and engine

[0001] This application claims priority to Chinese Patent Application No. 202421241527.9, filed on May 31, 2024, entitled "Lubrication Device and Engine", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of engine technology, and more specifically, relates to a lubrication device and an engine. Background Technology

[0003] The engine lubrication system is a crucial component of the engine. Its primary function is to reduce friction and wear between the engine's moving parts, while also providing cooling, cleaning, sealing, and rust prevention. It has a vital impact on the engine's reliability and durability. The engine lubrication system mainly includes the oil pan, oil pump, oil filter, oil cooler, main oil passage, branch oil passage, pressure relief valve, oil pressure sensor, and dipstick. When the engine is running, the oil pump draws lubricating oil from the oil pan through the suction port, pressurizes it, and delivers it to the main oil passage. Then, the oil flows along... The oil flows through the distribution channels to various parts that require lubrication, such as the crankshaft, connecting rods, and camshaft, forming an oil film on the surfaces of these components to reduce friction. At the same time, the oil also carries away the heat generated by friction, playing a cooling role. After lubrication and cooling, part of the oil flows back to the oil pan, while the other part continues to circulate. The oil filter continuously filters impurities from the oil to maintain its cleanliness, while the pressure relief valve ensures that the oil pressure is maintained within a suitable range to guarantee the normal operation of the lubrication system. The oil pressure sensor monitors the oil pressure in real time, providing information to the vehicle's control system.

[0004] However, the position of the oil suction port in the current engine lubrication system is fixed. During vehicle operation, the oil level in the oil pan will move relative to the oil pan as the vehicle tilts. Since the position of the oil suction port in the lubrication system is fixed, there is a possibility that the oil suction port may be at least partially higher than the oil level, causing air to be drawn into the lubrication system and affecting the lubrication effect. Technical issues

[0032] Furthermore, 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0033] As described in the background section, the engine lubrication system is a crucial component of the engine. Its primary function is to reduce friction and wear between the engine's moving parts, while also providing cooling, cleaning, sealing, and rust prevention. It has a vital impact on the engine's reliability and durability. The engine lubrication system mainly includes the oil pan, oil pump, oil filter, oil cooler, main oil passage, branch oil passage, pressure relief valve, oil pressure sensor, and dipstick. When the engine is running, the oil pump draws lubricating oil from the oil pan through the suction port, pressurizes it, and delivers it to the main oil passage. Afterward, the engine oil flows along the oil channels to various parts that require lubrication, such as the crankshaft, connecting rods, and camshaft, forming an oil film on the surfaces of these components to reduce friction. Simultaneously, the oil carries away the heat generated by friction, providing a cooling effect. After lubrication and cooling, some of the oil flows back to the oil pan, while the rest continues to circulate. The oil filter continuously filters impurities from the oil, maintaining its cleanliness. The pressure relief valve ensures that the oil pressure is maintained within a suitable range to guarantee the normal operation of the lubrication system. The oil pressure sensor monitors the oil pressure in real time, providing information to the vehicle's control system. However, currently, the position of the oil suction port in the engine lubrication system is fixed. During vehicle operation, the oil level in the oil pan moves relative to the oil pan as the vehicle tilts. Because the position of the oil suction port in the lubrication system is fixed, there is a possibility that at least part of the suction port may be higher than the oil level, causing air to be drawn into the lubrication system and affecting its lubrication effect.

[0034] Referring to Figures 1 to 7, in order to solve the above problems, according to one aspect of this application, an embodiment of this application provides a lubrication device for lubricating moving parts of an engine. The lubrication device includes an oil supply section 10 and a lubrication section 20, wherein the oil supply section 10 is provided with a receiving cavity 11 for containing engine oil; the lubrication section 20 includes a lubrication assembly and an oil inlet assembly 21, the lubrication assembly for drawing the engine oil from the receiving cavity 11 and delivering the engine oil to the moving parts of the engine, the oil inlet assembly 21 is movably disposed at the bottom of the receiving cavity 11, the input end of the oil inlet assembly 21 is connected to the receiving cavity 11, and the output end of the oil inlet assembly 21 is connected to the input end of the lubrication assembly; when the oil supply section 10 is tilted, the oil inlet assembly 21 can move towards the lower part of the bottom of the receiving cavity 11. The lubrication device provided in this embodiment connects the input end of the oil inlet assembly 21 to the receiving cavity 11 and the output end of the oil inlet assembly 21 to the input end of the lubrication assembly. This allows the lubrication assembly to draw oil from the receiving cavity 11 through the oil inlet assembly 21. Simultaneously, by movably positioning the oil inlet assembly 21 at the bottom of the receiving cavity 11, it can move towards the lower part of the receiving cavity 11 under its own weight when the oil supply section 10 is tilted. This ensures that the input end of the oil inlet assembly 21 is always below the oil level, preventing air intake and effectively improving the reliability of the lubrication device provided in this embodiment.

[0035] Referring to Figures 1 to 4, in one specific embodiment, the lubrication unit 20 further includes a flexible connecting component 22. The input end of the flexible connecting component 22 is connected to the output end of the oil inlet component 21, and the output end of the flexible connecting component 22 is connected to the output end of the lubrication component. Oil in the oil inlet component 21 can be transported to the lubrication component through the flexible connecting component 22. By connecting the input end of the flexible connecting component 22 to the output end of the oil inlet component 21 and the output end of the flexible connecting component 22 to the input end of the lubrication component, oil in the oil inlet component 21 can be transported to the lubrication component through the flexible connecting component 22. Simultaneously, by using the flexible connecting component 22 to connect the oil inlet component 21 and the lubrication component, the oil inlet component 21 can move relative to the lubrication component.

[0036] In one optional embodiment, the flexible connection component 22 provided in this embodiment includes a flexible connection tube, the input end of which is connected to the output end of the oil inlet component 21, and the output end of which is connected to the input end of the lubrication component.

[0037] Referring to Figures 3 and 4, in one specific embodiment, the oil inlet assembly 21 includes an oil inlet body 211 and a moving assembly. The moving assembly is mounted on the oil inlet body 211, allowing the oil inlet body 211 to move at the bottom of the receiving cavity 11 via the moving assembly. By providing the moving assembly on the oil inlet body 211, the oil inlet body 211 provided in this embodiment can move at the bottom of the receiving cavity 11 via the moving assembly.

[0038] In an optional embodiment, the oil inlet body 211 provided in this embodiment is provided with an oil inlet cavity and a first opening and a second opening communicating with the oil inlet cavity. The oil inlet cavity provided in this embodiment can communicate with the receiving cavity 11 through the first opening and with the input end of the flexible connecting pipe through the second opening. The first opening forms the input end of the oil inlet assembly 21, and the second opening forms the output end of the oil inlet assembly 21.

[0039] Referring to Figures 4 and 5, in one specific embodiment, the moving component includes a moving ball 212. The oil inlet body 211 has a first mounting recess on one side near the bottom of the receiving cavity 11. The moving ball 212 is rotatably mounted in the first mounting recess and at least partially protrudes from the first mounting recess. The oil inlet body 211 can move at the bottom of the receiving cavity 11 by means of the moving ball 212. By providing a first mounting recess on the side of the oil inlet body 211 near the bottom of the receiving cavity 11, and rotatably mounting the movable ball 212 on the first mounting recess, while allowing the movable ball 212 to at least partially protrude from the first mounting recess, the movable ball 212 provided in this embodiment can abut against the bottom of the receiving cavity 11 under the action of its own weight. This allows the movable assembly to move on the bottom of the receiving cavity 11 via the movable ball 212. At the same time, the oil inlet assembly 21 provided in this embodiment abuts against the bottom of the receiving cavity 11 via the movable ball 212, transforming the friction between the oil inlet assembly 21 and the bottom of the receiving cavity 11 into rolling friction. This effectively reduces the frictional force between the oil inlet assembly 21 and the bottom of the receiving cavity 11, making the movement of the oil inlet assembly 21 easier. Consequently, the oil inlet assembly 21 can move towards the lower part of the bottom of the receiving cavity 11 in a timely manner when the oil supply section 10 is tilted.

[0040] In one optional embodiment, the first mounting recess and the movable ball 212 provided in this embodiment are multiple, the multiple first mounting recesses are arranged at intervals along the circumference of the oil inlet body 211, and the multiple movable balls 212 correspond one-to-one with the multiple first mounting recesses.

[0041] Referring to Figure 6, in one specific embodiment, the lubrication device further includes an adsorption section 30, which includes a ferromagnetic adsorption plate 31 and a magnetic adsorption element. The ferromagnetic adsorption plate 31 is disposed at the bottom of the receiving cavity 11, and the magnetic adsorption element is disposed on the oil inlet assembly 21. The oil inlet assembly 21 is adsorbed onto the ferromagnetic adsorption plate 31 by the magnetic adsorption element. When the oil supply section 10 is tilted, the oil inlet assembly 21 can overcome the friction between the magnetic adsorption element and the ferromagnetic adsorption plate 31 and move towards the lower part of the bottom of the receiving cavity 11. By providing a ferromagnetic adsorption plate 31 at the bottom of the receiving cavity 11 and a magnetic adsorption component on the oil inlet assembly 21, the oil inlet assembly 21 provided in this embodiment can be adsorbed at the bottom of the receiving cavity 11 through the cooperation of the ferromagnetic adsorption plate 31 and the magnetic adsorption component. Furthermore, the friction generated by the mutual adsorption between the magnetic adsorption component and the ferromagnetic adsorption plate 31 can also prevent the oil inlet assembly 21 from moving when the oil supply section 10 is not tilted. At the same time, by providing a magnetic adsorption component on the oil inlet assembly 21, ferromagnetic impurities in the oil located near the oil inlet assembly 21 can also be adsorbed onto the magnetic adsorption component, thereby reducing impurities in the oil entering the input end of the oil inlet assembly 21.

[0042] In one optional embodiment, the magnetic adsorption element provided in this embodiment is made of magnet.

[0043] In one optional embodiment, the ferromagnetic adsorption plate 31 provided in this embodiment is made of ferromagnetic material.

[0044] Referring to Figures 6 and 7, in one specific embodiment, the magnetic adsorption component includes a magnetic ball bearing 32. A second mounting recess is provided on the side of the oil inlet assembly 21 near the bottom of the receiving cavity 11. The magnetic ball bearing 32 is rotatably mounted in the second mounting recess and at least partially protrudes from the second mounting recess. The oil inlet assembly 21 can be adsorbed onto the ferromagnetic adsorption plate 31 by the magnetic ball bearing 32. When the oil supply part 10 is tilted, the oil inlet assembly 21 can overcome the friction between the magnetic adsorption component and the ferromagnetic adsorption plate 31 and move towards the lower part of the bottom of the receiving cavity 11. By providing a second mounting recess on the side of the oil inlet assembly 21 near the bottom of the receiving cavity 11, and rotatably mounting the magnetic ball 32 on the second mounting recess, while allowing the magnetic ball 32 to at least partially protrude from the second mounting recess, the oil inlet assembly 21 provided in this embodiment can be attracted to the ferromagnetic adsorption plate 31 by the magnetic ball 32. Furthermore, when the oil supply section 10 is tilted, the oil inlet assembly 21 can also move on the bottom of the receiving cavity 11 by the magnetic ball 32.

[0045] In one optional embodiment, there are multiple second mounting recesses and magnetic balls 32 provided in this embodiment. The multiple second mounting recesses are arranged at intervals along the circumference of the oil inlet assembly 21, and the multiple magnetic balls 32 correspond one-to-one with the multiple second mounting recesses.

[0046] In an optional embodiment, the movable ball 212 and / or magnetic ball 32 provided in this embodiment can abut against the side of the ferromagnetic adsorption plate 31 away from the bottom of the receiving cavity 11.

[0047] In an optional embodiment, the ferromagnetic adsorption plate 31 provided in this embodiment has a plurality of positioning recesses spaced apart on the side away from the bottom of the receiving cavity 11. When the oil supply part 10 provided in this embodiment is not tilted, the movable ball 212 or magnetic ball 32 provided in this embodiment can cooperate with one of the positioning recesses so that the oil suction component is positioned on the ferromagnetic adsorption plate 31.

[0048] In one alternative embodiment, the positioning recess provided in this embodiment gradually recesses from the edge to the center towards the bottom of the receiving cavity.

[0049] Referring to Figures 3 to 7, in one specific embodiment, the lubrication unit 20 further includes a first filter assembly 23. The first filter assembly 23 is disposed at the input end of the oil inlet assembly 21 and is used to filter the engine oil. By providing the first filter assembly 23 at the input end of the oil inlet assembly 21, the oil inlet assembly 21 provided in this embodiment can filter the engine oil delivered to the input end of the oil inlet assembly 21 through the first filter assembly 23, thereby preventing larger impurities from entering the oil inlet assembly 21.

[0050] In one specific embodiment, the lubrication part 20 further includes a buffer assembly, which is disposed on the oil inlet assembly 21. The oil inlet assembly 21 can collide with the inner wall of the receiving cavity 11 through the buffer assembly. By providing a buffer assembly on the oil inlet assembly 21 provided in this embodiment, the oil inlet assembly 21 can collide with the inner wall of the receiving cavity 11 through the buffer assembly, thereby avoiding rigid collision between the oil inlet assembly 21 and the inner wall of the receiving cavity 11.

[0051] In one optional embodiment, the buffer component provided in this embodiment is made of an elastic material that is insoluble in engine oil.

[0052] In one optional embodiment, the buffer assembly provided in this embodiment is disposed on the outside of the oil inlet assembly 21 and extends circumferentially along the oil inlet assembly 21.

[0053] Referring to Figures 3 and 4, in one specific embodiment, the input end of the oil inlet assembly 21 is located on the side of the oil inlet assembly 21 near the bottom of the receiving cavity 11. An oil inlet gap communicating with the receiving cavity 11 is formed between the input end of the oil inlet assembly 21 and the bottom wall of the receiving cavity 11, allowing the engine oil in the receiving cavity 11 to be transported to the input end of the oil inlet assembly 21 through the oil inlet gap. By locating the input end of the oil inlet assembly 21 on the side of the oil inlet assembly 21 near the bottom of the receiving cavity 11, the distance between the oil inlet assembly 21 and the engine oil surface can be increased, which is beneficial for oil intake at the input end of the oil inlet assembly 21. At the same time, by setting an oil inlet gap communicating with the receiving cavity 11 between the input end of the oil inlet assembly 21 and the bottom wall of the receiving cavity 11, the engine oil in the receiving cavity 11 can be transported to the input end of the oil inlet assembly 21 through the oil inlet gap.

[0054] In one optional embodiment, the oil supply unit 10 provided in this embodiment includes an oil pan, and the receiving cavity 11 provided in this embodiment is disposed inside the oil pan.

The input end of the rotary connecting assembly provided in this embodiment is connected to the oil inlet assembly 21, and the output end of the rotary connecting assembly is rotatably mounted on the input end of the lubrication assembly and connected to the input end of the lubrication assembly. The rotary connecting assembly can restrict the movement of the oil inlet assembly 21, so that the oil inlet assembly 21 can move in a circular motion at the bottom of the receiving cavity 11 along the rotation axis of the output end of the rotary connecting assembly. This allows the oil inlet assembly 21 to move in a circular manner towards the lower part of the bottom of the receiving cavity 11 when the oil supply part 10 is tilted.

[0057] In an optional embodiment, the oil inlet assembly 21 provided in this embodiment is movably mounted on the rotary connecting assembly. When the bottom of the receiving cavity 11 provided in this embodiment has an uneven structure, the oil inlet assembly 21 can adapt to the uneven structure at the bottom of the receiving cavity 11 by adjusting its position relative to the rotary connecting assembly, thereby avoiding interference between the oil inlet assembly 21 and the bottom of the receiving cavity 11 during movement.

[0058] In an optional embodiment, the lubrication part 20 provided in this embodiment further includes an elastic reset component. The elastic reset component provided in this embodiment is disposed on the rotary connection component and abuts against the oil inlet component 21. It is used to apply an elastic force to the oil inlet component 21 near the bottom of the receiving cavity 11, so that the oil inlet component 21 can abut against the bottom of the receiving cavity 11 without the action of external force.

[0059] In an optional embodiment, the lubrication part 20 provided in this embodiment further includes a counterweight. The oil inlet assembly 21 provided in this embodiment is provided with a groove extending in a preset direction. The counterweight provided in this embodiment is slidably mounted on the groove. When the oil supply part 10 provided in this embodiment is tilted in the preset direction, the counterweight can move in the preset direction under the action of gravity and impact the oil inlet assembly 21, thereby enabling the oil inlet assembly 21 to start moving quickly.

[0060] According to another aspect of this application, an engine is provided, the engine including a lubrication device, the lubrication device being the lubrication device described above.

[0061] In summary, implementing the lubrication device and engine provided in this embodiment has at least the following beneficial technical effects: The lubrication device provided in this embodiment, by setting the input end of the oil inlet component 21 to communicate with the receiving cavity 11 and setting the output end of the oil inlet component 21 to communicate with the input end of the lubrication component, enables the lubrication component to draw oil from the receiving cavity 11 through the oil inlet component 21. At the same time, by movably setting the oil inlet component 21 provided in this embodiment at the bottom of the receiving cavity 11, the oil inlet component 21 can move to the lower part of the bottom of the receiving cavity 11 by its own gravity when the oil supply part 10 is tilted, so that the input end of the oil inlet component 21 can always be below the oil level, avoiding the phenomenon of air intake, and effectively improving the reliability of the lubrication device provided in this embodiment.

[0062] The above are merely preferred embodiments of this application and are not intended to limit this application.
