[0034] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0035] In the description of the present invention, "plurality" means two or more.

[0036] First, a vehicle according to an embodiment of the present invention will be described with reference to the drawings.

[0037] The vehicle according to the embodiment of the present invention includes an engine 900 and a cooling and lubricating system 1 , and a controller 400 of the cooling and lubricating system 1 is connected to the engine 900 .

[0038] The cooling lubrication system 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] like Figure 1-Figure 3As shown, the driving member 100, the oil pump 200 and the cooling water pump 300 are connected in series in sequence, the oil pump 200 is used to pump the lubricating oil in the oil pan 210, the cooling water pump 300 is used to pump the coolant in the water tank 310, and the controller 400 is connected to the driving member 100. The controller 400 adjusts the output oil pressure of the oil pump 200 according to the required oil pressure value; and / or the controller 400 adjusts the output flow of the cooling water pump 300 according to the required heat dissipation.

[0040] According to the cooling and lubrication system 1 of the embodiment of the present invention, the driving part 100, the oil pump 200 and the cooling water pump 300 are connected in series in sequence, the oil pump 200 is used to pump the lubricating oil in the oil pan 210, and the lubricating oil pumped by the oil pump 200 can lubricate the engine 900 and other transmission parts, and the cooling water pump 300 is used to pump the coolant in the water tank 310, and the coolant pumped by the cooling water pump 300 can cool the engine 900 and other transmission parts.

[0041] In this way, the oil pump 200 and the cooling water pump 300 can be integrated into one module, and the oil pump 200 and the cooling water pump 300 can share the same driving component 100, which not only reduces the number of components of the cooling lubrication system 1 and makes the structure of the cooling lubrication system 1 simpler, but also can make the overall volume of the cooling lubrication system 1 smaller, the installation and layout space required for the cooling lubrication system 1 is smaller, and disassembly and assembly are more convenient.

[0042] In addition, the controller 400 is connected to the driving member 100. The controller 400 can control the driving member 100 to drive the oil pump 200 and the cooling water pump 300 to work according to the speed and torque of the engine 900, and the control accuracy is higher. Since the driving member 100, the oil pump 200 and the cooling water pump 300 are arranged in series, the power of the driving member 100 can be transmitted to the oil pump 200 and the cooling water pump 300 in sequence. The oil pump 200 and the cooling water pump 300 can jointly lubricate and cool the engine 900 and other transmission parts. The power connection method between the driving member 100, the oil pump 200 and the cooling water pump 300 is simpler, and the power transmission is more stable and reliable. The controller 400 can perform different power transmissions according to the required oil pressure value and the required heat dissipation, so that the output oil pressure of the oil pump 200 matches the required oil pressure value, and the output flow of the cooling water pump 300 matches the required heat dissipation, and the control accuracy of the cooling and lubrication system 1 is higher.

[0043] In addition, the controller 400 adjusts the output oil pressure of the oil pump 200 according to the required oil pressure value, wherein the controller 400 can calculate the output oil pressure of the oil pump 200 corresponding to the required oil pressure value according to the rotational speed of the engine 900, the torque of the engine 900, the oil temperature and oil pressure of the lubricating oil between the oil pump 200 and the engine 900. At this time, the required driving speed of the oil pump 200 can be calculated according to the output oil pressure of the oil pump 200, so that the driving component 100 outputs corresponding power to the oil pump 200. The output oil pressure of the oil pump 200 is more accurate, which avoids power loss, is beneficial to saving energy consumption, and avoids insufficient output oil pressure, thereby satisfying the lubrication of the engine 900 and other transmission components.

[0044] In addition, the controller 400 adjusts the output flow of the cooling water pump 300 according to the required heat dissipation, wherein the controller 400 can calculate the output flow of the cooling water pump 300 corresponding to the required heat dissipation according to the speed of the engine 900, the torque of the engine 900, the temperature and pressure of the coolant between the cooling water pump 300 and the engine 900, and calculate the required driving speed of the cooling water pump 300 according to the output flow of the cooling water pump 300, so that the driving component 100 outputs corresponding power to the cooling water pump 300, and the output flow of the cooling water pump 300 is more accurate, which avoids power loss, is beneficial to saving energy consumption, and avoids insufficient output flow, thereby satisfying the cooling of the engine 900 and other transmission components.

[0045] As such, the cooling and lubrication system 1 according to the embodiment of the present invention has the advantages of high integration, precise control and low energy consumption.

[0046] The vehicle according to the embodiment of the present invention has the advantages of high integration, fine control and low energy consumption by utilizing the cooling and lubrication system 1 according to the above-mentioned embodiment of the present invention.

[0047] In some specific embodiments of the present invention, the driving member 100 is a motor, and the controller 400 adjusts the output speed of the motor according to the required oil pressure value and / or the required heat dissipation.

[0048] It is understandable that the different speeds of the motor need to change according to different required oil pressure values ​​and different required heat dissipation. For example, when the required oil pressure value is large, the output speed of the motor needs to be large so that the motor can output sufficient power to the oil pump 200, and the output oil pressure of the oil pump 200 can meet the required oil pressure value; or, when the required heat dissipation is large, the output speed of the motor also needs to be large so that the motor can output sufficient power to the cooling water pump 300, and the output flow of the cooling water pump 300 can be large, thereby improving the heat dissipation efficiency of the engine 900.

[0049] Therefore, by controlling the output speed of the motor through the controller 400, the power output of the motor can be matched with the required oil pressure value and the required heat dissipation, thereby avoiding insufficient output power of the motor or power waste. The control accuracy is higher, and both low energy consumption and high efficiency can be taken into account.

[0050] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the cooling and lubricating system 1 further includes a flow regulating element 500 .

[0051] The flow regulating member 500 is connected to the cooling water pump 300 , and the controller 400 is connected to the flow regulating member 500 . The controller 400 controls the output flow of the cooling water pump 300 by controlling the flow regulating member 500 .

[0052] For example, when the heat dissipation is excessive, that is, when the output flow of the cooling water pump 300 is greater than the required heat dissipation, the flow rate of the coolant output by the cooling water pump 300 to the engine 900 for cooling can be reduced by adjusting the flow regulating member 500, thereby avoiding the situation where the output flow of the cooling water pump 300 is greater than the heat dissipation required by the engine 900, resulting in increased fuel consumption and increased exhaust pollution of the engine 900, and avoiding the situation where the output flow of the cooling water pump 300 is less than the heat dissipation required by the engine 900, resulting in an increase in the temperature of the engine 900, thereby ensuring the service life and working performance of the engine 900.

[0053] Furthermore, if Figure 1 and Figure 2 As shown, the cooling water pump 300 has a first liquid inlet 320 and a first liquid outlet 330, the first liquid inlet 320 is connected to the water tank 310, the flow regulating member 500 is a first control valve, the first liquid outlet 330 is connected to the water tank 310 through the flow regulating member 500, and the controller 400 adjusts the output flow of the cooling water pump 300 by adjusting the opening of the flow regulating member 500. The first control valve may be a relief valve.

[0054] Specifically, when the cooling water pump 300 is working, the cooling water pump 300 can draw coolant from the water tank 310 through the first liquid inlet 320, and the coolant flows from the first liquid inlet 320 to the first liquid outlet 330, and flows to the flow regulating member 500 and the engine 900 through the first liquid outlet 330. When the opening of the flow regulating member 500 is 0, all the coolant output by the cooling water pump 300 flows to the engine 900 to dissipate heat for the engine 900. As the opening of the flow regulating member 500 increases, a part of the coolant output by the cooling water pump 300 flows to the engine 900 and other transmission components to dissipate heat and cool the engine 900 and the transmission components. Another part of the coolant output by the cooling water pump 300 flows back to the water tank 310 through the flow regulating member 500.

[0055] By changing the opening of the flow regulating member 500, the flow rate of the coolant output by the cooling water pump 300 flowing back to the water tank 310 can be changed, thereby changing the flow rate of the coolant output by the cooling water pump 300 flowing to the engine 900, so as to achieve the adaptation of the output flow rate of the cooling water pump 300 and the heat dissipation required by the engine 900, thereby further improving the accuracy of the output flow rate of the cooling water pump 300.

[0056] Of course, it is understandable that the flow regulating member 500 is not limited to the overflow valve, but may also be other control valves capable of controlling the flow of coolant outputted from the cooling water pump 300 to the engine 900 .

[0057] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the cooling and lubricating system 1 further includes an oil pressure regulating member 600 . The oil pressure regulating member 600 may be integrated into the oil pump 200 , or the oil pressure regulating member 600 may also be arranged in the oil passage of the engine 900 .

[0058] The oil pressure regulating member 600 is connected to the oil pump 200, and the controller 400 is connected to the oil pressure regulating member 600. The controller 400 controls the output oil pressure of the oil pump 200 by controlling the oil pressure regulating member 600. In this way, by setting the oil pressure regulating member 600, it is possible to prevent the output oil pressure of the oil pump 200 from being greater than the required oil pressure value, further avoiding power waste, making the output oil pressure of the oil pump 200 perfectly match the required oil pressure value, and the control accuracy of the cooling and lubrication system 1 is higher.

[0059] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the oil pump 200 has a second liquid inlet 220, a second liquid outlet 230 and a feedback port 240. The oil pump 200 may be a variable displacement oil pump.

[0060] The second liquid inlet 220 is connected to the oil pan 210, the oil pressure regulating member 600 is a second control valve and has a first channel 610, the second liquid outlet 230 is connected to the feedback port 240 through the first channel 610, and the controller 400 adjusts the output oil pressure of the oil pump 200 by adjusting the opening of the first channel 610. The second control valve may be a proportional valve.

[0061] Specifically, the oil pump 200 can draw lubricating oil in the oil pan 210 through the second liquid inlet 220, and a portion of the lubricating oil outputted from the second liquid outlet 230 of the oil pump 200 flows directly to the engine 900, and another portion of the lubricating oil outputted from the second liquid outlet 230 of the oil pump 200 is fed back to the feedback port 240 of the oil pump 200 through the oil pressure regulating component 600. The controller 400 adjusts the opening of the first channel 610 by combining the speed of the engine 900, the torque of the engine 900, and the oil temperature and oil pressure of the lubricating oil discharged by the oil pump 200, so as to adjust the flow rate fed back from the oil pressure regulating component 600 to the feedback port 240 of the oil pump 200, so as to change the output oil pressure of the oil pump 200 and achieve a perfect match between the output oil pressure of the oil pump 200 and the required oil pressure value.

[0062] For example, the oil pressure of the lubricating oil fed back to the feedback port 240 of the oil pump 200 can adjust the eccentricity of the oil pump 200 , thereby changing the flow rate of the lubricating oil at the second liquid outlet 230 of the oil pump 200 .

[0063] Furthermore, if Figure 1-Figure 2 As shown, the oil pressure regulating member 600 also has a second channel 620, and the feedback port 240 is connected to the oil pan 210 through the second channel 620, and the opening of the second channel 620 is controlled by the controller 400. By connecting the feedback port 240 with the second channel 620, the lubricating oil flowing into the oil pump 200 through the feedback port 240 can directly flow back to the oil pan 210 through the feedback port 240, and at this time, the second liquid outlet 230 is not connected to the first channel 610 of the oil pressure regulating member 600, and the lubricating oil flowing out through the second liquid outlet 230 can all flow to the engine 900, so as to realize the oil supply of the oil pump 200 with the maximum displacement.

[0064] In some specific embodiments of the present invention, the oil pump 200 and the oil pressure regulating member 600 are formed as one body. In this way, on the one hand, the overall structure of the oil pump 200 and the oil pressure regulating member 600 can be simplified, which is convenient for the processing and manufacturing of the oil pump 200 and the oil pressure regulating member 600, and is conducive to improving the connection strength of the oil pump 200 and the oil pressure regulating member 600. On the other hand, the overall volume of the oil pump 200 and the oil pressure regulating member 600 can be made smaller, which is convenient for miniaturization of the cooling and lubricating system 1, so as to facilitate the installation and layout of the cooling and lubricating system 1.

[0065] In some specific embodiments of the present invention, Figure 1 As shown, the cooling and lubrication system 1 further includes a clutch 700 .

[0066] The cooling water pump 300 is transmission-connected to the oil pump 200 via the clutch 700 , and the controller 400 is connected to the clutch 700 . The controller 400 controls the clutch 700 according to the temperature of the coolant in the water tank 310 to control whether the power of the oil pump 200 is transmitted to the cooling water pump 300 .

[0067] Among them, when the clutch 700 is closed, the power of the driving member 100 can be transmitted to the cooling water pump 300 through the oil pump 200. When the clutch 700 is disconnected, the cooling water pump 300 and the oil pump 200 are disconnected from each other, and the power of the driving member 100 will not be transmitted to the cooling water pump 200. At this time, the driving member 100 only drives the oil pump 200 to operate and the cooling water pump 300 does not operate.

[0068] It should be noted that the temperature of the coolant in the engine 900 decreases after the vehicle has been parked for a long time, especially in winter. Due to the low temperature, the temperature of the coolant will drop rapidly. When restarting the engine 900, the coolant temperature is too low, which will affect the fuel consumption and exhaust pollution of the engine 900. Therefore, it is necessary to warm up the engine to increase the temperature of the coolant to reduce fuel consumption and pollution, so as to achieve the purpose of protecting the engine 900.

[0069] For example, when the engine 900 is just started and the temperature of the coolant is lower than the set temperature, the vehicle enters a warm-up condition and the temperature of the coolant needs to rise quickly. At this time, the controller 400 controls the clutch 700 to cut off the power, so that the clutch 700 is disconnected, and no power is transmitted between the drive component 100 and the cooling water pump 300, so that the drive component 100 only drives the oil pump 200 to work and does not drive the cooling water pump 300 to work, and the coolant in the water tank 310 will not be pumped out, so that the temperature of the coolant in the water tank 310 can rise quickly, thereby reducing the warm-up time.

[0070] When the temperature of the coolant rises to the set temperature, the controller 400 controls the clutch 700 to be powered on and closed, and the output power of the driving member 100 is transmitted to the cooling water pump 300 through the oil pump 200 and the clutch 700, so that the driving member 100 drives the cooling water pump 300 to work while driving the oil pump 200. At this time, the cooling water pump 300 can pump coolant from the water tank 310 to cool the engine 900, thereby ensuring the functional performance of the engine 900.

[0071] In some specific embodiments of the present invention, Figure 1 and Figure 2As shown, the cooling and lubricating system 1 further includes a transmission 800, and the oil pump 200 is connected to the driving member 100 through the transmission 800, wherein the transmission 800 has a transmission wheel 810, and the transmission wheel 810 is connected to the driving member 100. In this way, the power transmission ratio between the driving member 100 and the oil pump 200 can be changed through the transmission 800, so as to realize different power transmission between the driving member 100 and the oil pump 200, that is, the output torque of the driving member 100 and the input torque of the oil pump 200 can be different, and the output speed of the driving member 100 and the input speed of the oil pump 200 can be different, so that the power variation range of the oil pump 200 and the cooling water pump 300 is larger, and the power requirements of the oil pump 200 and the cooling water pump 300 are further met, so that the output oil pressure of the oil pump 200 can meet the required oil pressure value of the engine 900, and the output flow of the cooling water pump 300 can meet the required heat dissipation value of the engine 900.

[0072] In some specific embodiments of the present invention, Figure 2 As shown, the cooling and lubricating system 1 further includes a clutch device 710 . The clutch device 710 is sleeved on the rotating shaft 250 of the oil pump 200 . The clutch device 710 is fixedly connected to the housing of the cooling and lubricating system 1 .

[0073] In this embodiment, the housing of the cooling and lubricating system 1 may be the housing of the oil pump, that is, the clutch device 710 may be fixedly connected to the housing of the oil pump 200; the housing of the cooling and lubricating system 1 may be a common housing of the oil pump and the cooling water pump, that is, the oil pump 200 and the cooling water pump 300 share a housing, and the clutch device 710 may be fixedly connected to the housing shared by the oil pump 200 and the cooling water pump 300; in addition, the clutch device 710 may be fixedly connected to the housings of other components in the cooling and lubricating system 1. The clutch device 710 drives the transmission wheel 810, and the transmission wheel 810 drives the rotating shaft 250 of the oil pump 200 to engage or separate with the rotating shaft of the cooling water pump 300.

[0074] In this way, when the clutch device 710 is energized, the power of the driving member 100 can be transmitted to the cooling water pump 300 through the oil pump 200. When the clutch device 710 is de-energized, the cooling water pump 300 and the oil pump 200 are disconnected from each other, and the power of the driving member 100 will not be transmitted to the cooling water pump 200. At this time, the driving member 100 only drives the oil pump 200 to operate and the cooling water pump 300 does not operate.

[0075] It should be noted that, compared with the above-mentioned clutch 700, the clutch 700 is arranged between the oil pump 200 and the cooling water pump 300, while the clutch device 710 is not arranged between the cooling water pump 300 and the oil pump 200. The structures of the clutch 700 and the clutch device 710 may be the same or different, but the clutch 700 and the clutch device 710 are both able to realize the power transmission between the oil pump 200 and the cooling water pump 300 or interrupt the power transmission between the oil pump 200 and the cooling water pump 300 to realize the power transmission between the cooling water pump 300 and the driving member 100.

[0076] Furthermore, by setting different clutches, the clutch 700 and the clutch device 710 can be arranged at different locations of the cooling and lubrication system 1. That is, the arrangement position of the clutch can be selected according to the actual structure of the cooling and lubrication system 1, making the spatial layout of the cooling and lubrication system 1 more reasonable.

[0077] Furthermore, if Figure 3 As shown, the clutch device 710 includes an electromagnetic part 711 and an elastic member 712 .

[0078] The electromagnetic part 711 is sleeved on the rotating shaft 250 of the oil pump 200, and the electromagnetic part 711 is fixedly connected to the housing of the cooling and lubricating system 1, and the two ends of the elastic member 712 are respectively connected to the electromagnetic part 711 and the transmission wheel 810. In the first state where the electromagnetic part 711 is not powered, the elastic member 712 elastically deforms to generate a first elastic force, and the first elastic force is used to tightly connect the rotating shaft of the oil pump with the transmission wheel; in the second state where the electromagnetic part 711 is powered, the electromagnetic part 711 generates an electromagnetic force, and the electromagnetic force is used to drive the transmission wheel 810, and the transmission wheel 810 drives the rotating shaft 250 of the oil pump 200 to move toward the rotating shaft of the cooling water pump 300 until the rotating shaft 250 of the oil pump 200 is combined with the rotating shaft of the cooling water pump 300.

[0079] Specifically, there may be a gap between the electromagnetic part 711 and the rotating shaft 250, and the rotating shaft 250 may move relative to the electromagnetic part 711 along its axial direction. One end of the elastic member 712 abuts against the electromagnetic part 711 and the other end abuts against the transmission wheel 810 of the transmission 800. The transmission wheel 800 and the rotating shaft 250 may be interference-connected, that is, the rotating shaft 250 and the transmission wheel 800 may move together. The rotating shaft 250 of the oil pump 200 and the rotating shaft of the cooling water pump 300 may be spline-fitted or concave-convex-tooth-fitted.

[0080] In some embodiments of the present invention, when the clutch device 710 is energized, the electromagnetic part 711 generates an electromagnetic force, i.e., a magnetic attraction force, so that the transmission wheel 810 of the transmission 800 moves toward the direction of the rotating shaft of the cooling water pump 300. At this time, the transmission wheel 810 will drive the rotating shaft 250 of the oil pump 200 to move toward the direction of the rotating shaft of the cooling water pump 300. The elastic member 712 is compressed and deformed, so that the rotating shaft of the oil pump 200 and the rotating shaft of the cooling water pump 300 are combined and connected for transmission. The power of the driving member 100 can be transmitted to the oil pump 200, and can also be transmitted to the rotating shaft of the cooling water pump 300 through the rotating shaft 250 of the oil pump 200.

[0081] When the clutch device 710 is powered off, the electromagnetic part 711 does not generate electromagnetic force, and the elastic force of the elastic member 712 pushes the transmission wheel 810 of the transmission 800 to move in the direction away from the rotating shaft of the cooling water pump 300. At this time, the transmission wheel 810 will drive the rotating shaft 250 of the oil pump 200 to move in the direction away from the rotating shaft of the cooling water pump 300, so that the transmission connection between the oil pump 200 and the cooling water pump 300 is disconnected, and the power of the driving member 100 can only be transmitted to the rotating shaft 250 of the oil pump 200.

[0082] It should be noted that when no power is supplied, the elastic member 712 is deformed so that the transmission wheel 810 is tightly connected to the rotating shaft 250 of the oil pump 200. This can keep the rotating shaft 250 of the oil pump 200 disconnected from the rotation speed of the cooling water pump 300, thereby avoiding the possibility of accidental connection between the two. On the other hand, it also improves the connection stability between the transmission wheel 810 and the rotating shaft 250.

[0083] In addition, in this embodiment, when the electromagnetic part 711 is not energized, the elastic member 712 can also be in a normal state, that is, the elastic member 712 is neither compressed nor stretched, the elastic member 712 has no elastic force at this time, and there is a certain gap between the rotating shaft 250 of the oil pump 200 and the rotating shaft of the cooling water pump 300, so that the rotating shaft 250 of the oil pump 200 is disconnected from the rotating shaft of the cooling water pump 300.

[0084] In some specific embodiments of the present invention, the transmission 800 includes at least one of a gear transmission device and a belt transmission device.

[0085] For example, the transmission 800 can be a combination of a gear transmission device and a belt transmission device. In this case, there are two-stage speed changes between the oil pump 200 and the drive member 100 to expand the speed range. Alternatively, the transmission 800 is only driven by a gear transmission device, or alternatively, the transmission 800 is only driven by a belt transmission device. The transmission 800 has more types of power transmission modes and reliable power transmission, so that the power transmission between the drive member 100 and the oil pump 200 can be realized more stably and reliably.
