[0036] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0037] In the description of the present invention, "plurality" means two or more.

[0038] First, a vehicle according to an embodiment of the present invention will be described with reference to the drawings.

[0039] 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 .

[0040] The cooling lubrication system according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figure 1-Figure 3 As shown, the cooling and lubrication system 1 according to the embodiment of the present invention includes a driving member 100 , an oil pump 200 , a cooling water pump 300 and a controller 400 .

[0042] The oil pump 200 and the cooling water pump 300 are connected in parallel and are respectively connected to the driving member 100. The oil pump 200 is used to pump the lubricating oil in the oil pan 210, and the cooling water pump 300 is used to pump the coolant in the water tank 310. 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.

[0043] According to the cooling and lubrication system 1 of the embodiment of the present invention, the oil pump 200 and the cooling water pump 300 are connected in parallel and are respectively connected to the driving member 100 in a transmission manner. 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. 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.

[0044] 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.

[0045] 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 rotational speed and torque of the engine 900, so the control accuracy is higher. Since the oil pump 200 and the cooling water pump 300 are arranged in parallel, that is, the oil pump 200 and the cooling water pump 300 are two independently working components, the oil pump 200 and the cooling water pump 300 can jointly lubricate and cool the engine 900 and other transmission components. The controller 400 can realize different proportions of power transmission according to the required oil pressure value and the required heat dissipation. For example, the controller 400 can adjust the power distribution of the driving member 100 to the oil pump 200 and the cooling water pump 300 according to the ratio of the required oil pressure value and the required heat dissipation, so that the control accuracy of the cooling and lubrication system 1 is higher.

[0046] 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 transmission parts.

[0047] 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 meeting the cooling and cooling of the engine 900 and other transmission components.

[0048] 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.

[0049] 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 embodiment of the present invention.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the cooling and lubricating system 1 further includes a flow regulating element 500 .

[0054] 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 .

[0055] 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 and used to cool the engine 900 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.

[0056] Furthermore, if Figure 1-Figure 3 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.

[0057] 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.

[0058] 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.

[0059] 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 .

[0060] In some specific embodiments of the present invention, Figure 1-Figure 3As 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 .

[0061] 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.

[0062] In some specific embodiments of the present invention, Figure 1-Figure 3 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.

[0063] 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.

[0064] 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.

[0065] 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 .

[0066] Furthermore, if Figure 1-Figure 3As 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.

[0067] 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.

[0068] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the cooling and lubrication system 1 further includes a clutch 700 .

[0069] The cooling water pump 300 is connected to the driving member 100 through 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 driving member 100 is transmitted to the cooling water pump 300 .

[0070] When the clutch 700 is closed, the power of the driving member 100 can be transmitted to the cooling water pump 300. When the clutch 700 is disconnected, the driving member 100 and the cooling water pump 300 are disconnected, the power of the driving member 100 cannot be transmitted to the cooling water pump 300, and the cooling water pump 300 does not operate.

[0071] 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.

[0072] 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 but does not drive the cooling water pump 300 to stop working, and the coolant in the water tank 310 will not be pumped out, so the temperature of the coolant in the water tank 310 can rise quickly, thereby reducing the warm-up time.

[0073] 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 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 pumps coolant from the water tank 310 to cool the engine 900, thereby ensuring the functional performance of the engine 900.

[0074] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the cooling and lubricating system 1 further includes a transmission 800, and the cooling water pump 300 is transmission-connected to the driving member 100 through the transmission 800. In this way, the power transmission ratio between the driving member 100 and the cooling water pump 300 can be changed through the transmission 800, so as to realize different power transmission between the driving member 100 and the cooling water pump 300, that is, the output torque of the driving member 100 and the input torque of the cooling water pump 300 can be different, and the output speed of the driving member 100 and the input speed of the cooling water pump 300 can be different, so as to further meet the power demand of the cooling water pump 300, so that the output flow of the cooling water pump 300 can meet the required heat dissipation of the engine 900.

[0075] Furthermore, if Figure 1-Figure 3 As shown, the transmission 800 includes at least one of a gear transmission device 810 and a belt transmission device 820 .

[0076] For example, the transmission 800 may be a combination of a gear transmission device 810 and a belt transmission device 820. In this case, there are two-stage speed changes between the cooling water pump 300 and the driving member 100, thereby expanding the speed change range. Alternatively, the transmission 800 is only driven by the gear transmission device 810, or alternatively, the transmission 800 is only driven by the belt transmission device 820. The transmission 800 has more types of power transmission modes and reliable power transmission, thereby realizing more stable and reliable power transmission between the driving member 100 and the cooling water pump 300.

[0077] In some specific embodiments of the present invention, Figure 1-Figure 3As shown, the driving member 100 and the oil pump 200 are connected via a coupling or a spline transmission. In this way, the transmission connection between the oil pump 200 and the driving member 100 is more stable, the oil pump 200 can rotate with the driving member 100, and the driving member 100 and the oil pump 200 can be separated, thereby facilitating the replacement of either the driving member 100 or the oil pump 200 and reducing maintenance costs.

[0078] In some other specific embodiments of the present invention, the driving member 100 and the oil pump 200 are integrally formed, which not only simplifies the structure of the oil pump 200 and the driving member 100, facilitates the processing and manufacturing of the oil pump 200 and the driving member 100, and is beneficial to improving the structural strength of the oil pump 200 and the driving member 100, but also can make the overall volume of the oil pump 200 and the driving member 100 smaller, the number of parts of the cooling and lubrication system 1 can be smaller, and it is easy to realize the miniaturization of the cooling and lubrication system 1, so as to facilitate the installation and layout of the cooling and lubrication system 1.

[0079] Other configurations and operations of the cooling and lubricating system 1 and the vehicle having the same according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail herein.
