Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0048] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0049] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0050] The first aspect of this application provides a cooling and lubrication system, such as Figure 1 and Figure 2 As shown, the cooling and lubrication system includes a heat exchange unit 2, a gearbox housing 1, a controller 3, and an oil outlet pipe 4. The gearbox housing 1 has a receiving cavity 101, a water inlet channel 102, and a water outlet channel 103.

[0051] The water inlet channel 102 and the water outlet channel 103 are located inside the gearbox housing 1.

[0052] The heat exchange unit 2 is installed on the gearbox housing 1 and is connected to the water inlet channel 102 and the water outlet channel 103 respectively.

[0053] The controller 3 is connected to the inlet channel 102 and the outlet channel 103 respectively.

[0054] The oil outlet pipe 4 is connected to the first oil outlet of the heat exchange unit 2.

[0055] The oil outlet pipe 4 and the receiving cavity 101 are located on opposite sides of the gearbox housing 1 and are connected.

[0056] Both the water inlet channel 102 and the water outlet channel 103 are located between the oil outlet pipe 4 and the receiving cavity 101.

[0057] Understandably, the gearbox housing 1, through the receiving cavity 101, can support and accommodate the power source and transmission mechanism, facilitating direct lubrication and cooling of the components located in the receiving cavity 101 via the oil outlet pipe 4. This shortens the length of the oil outlet pipe 4, reducing the space occupied. The water outlet channel 103 and the water inlet channel 102 facilitate the controller 3 to supply coolant to the heat exchange unit 2, cooling the lubricating oil within the heat exchange unit 2. Both the water outlet channel 103 and the water inlet channel 102 are located between the oil outlet pipe 4 and the receiving cavity 101, which improves the compactness of the cooling and lubrication system of this application, thereby reducing the space occupied.

[0058] In related technologies, the controller 3 is generally connected to the heat exchange unit 2 only via a flexible hose. The distance between the controller 3 and the heat exchange unit 2 is relatively far, resulting in a long flexible hose and thus occupying more space. Furthermore, the heat exchange unit 2 is also connected to the components to be cooled and lubricated only via a flexible hose, further increasing the space occupied by the cooling and lubrication system.

[0059] This application arranges an inlet water channel 102 and an outlet water channel 103 in the gearbox housing 1, and connects the controller 3 and the heat exchange unit 2 through the inlet water channel 102 and the outlet water channel 103. This helps to shorten the length of the pipes arranged in the gearbox housing 1 for connecting the controller 3 and the heat exchange unit 2, thereby reducing the space occupied.

[0060] In this embodiment, the heat exchange unit 2 can be circulated with coolant and lubricating oil. The coolant and lubricating oil are relatively close to each other and isolated from each other in the heat exchange unit 2, thereby achieving heat exchange between the two, reducing the temperature of the lubricating oil, and helping the lubricating oil to perform its lubrication and cooling functions.

[0061] In this embodiment, the gearbox housing 1 is used to support various transmission mechanisms and power sources. The components to be supported can be arranged inside the receiving cavity 101 and connected to the side wall of the receiving cavity 101, thereby being supported by the gearbox housing 1.

[0062] In this embodiment, the controller 3 can control the connection and disconnection with the water outlet channel 103 and the water inlet channel 102. When the controller 3 is connected to both the water inlet channel 102 and the water outlet channel 103, the coolant can complete heat exchange through the heat exchange unit 2; when the controller 3 is relatively closed to both the water inlet channel 102 and the water outlet channel 103, the coolant cannot pass through the heat exchange unit 2.

[0063] In this embodiment, the oil outlet pipe 4 can be attached to the gearbox housing 1, thereby reducing the space occupied.

[0064] In this embodiment, the gearbox housing 1 has a receiving cavity 101, a water inlet channel 102, and a water outlet channel 103. The gearbox housing 1 can be formed by casting by injecting liquid metal into the cavity. Within the cavity forming the gearbox housing 1, structures such as cores can be arranged at the locations of the receiving cavity 101, the water inlet channel 102, and the water outlet channel 103, so that the liquid metal naturally forms the receiving cavity 101, the water inlet channel 102, and the water outlet channel 103 after cooling.

[0065] In this embodiment, the water inlet channel 102 and the water outlet channel 103 are located inside the gearbox housing 1. Here, "inside the gearbox housing 1" refers to the portion of the gearbox housing 1 where the water inlet channel 102 and the water outlet channel 103 provide support and shelter, and the receiving cavity 101 is the cavity enclosed by this portion.

[0066] In this embodiment, the heat exchange unit 2 can be connected to the water inlet channel 102 and the water outlet channel 103 respectively by means of threaded connection or other means.

[0067] In this embodiment, the oil outlet pipe 4 and the receiving cavity 101 are located on opposite sides of the gearbox housing 1 and are connected. The receiving cavity 101 is located inside the gearbox housing 1, and the oil outlet pipe 4 is located outside the gearbox housing 1. This avoids interference between the oil outlet pipe 4 and the components located inside the receiving cavity 101.

[0068] In this embodiment, both the inlet channel 102 and the outlet channel 103 are located between the oil outlet pipe 4 and the receiving cavity 101. This reduces the length of the pipes added to connect the controller 3 and the heat exchange unit 2, thereby improving the compactness of the cooling and lubrication system and reducing the space occupied.

[0069] In this embodiment, the water outlet channel 103 penetrates the gearbox housing 1 along the first direction X. This facilitates the separation of the core forming the water outlet channel 103 from the gearbox housing 1 during casting. Furthermore, one end of the water outlet channel 103 penetrating the gearbox housing 1 can be connected to the heat exchange unit 2, and the other end can be connected to the controller 3 via a flexible hose or other connecting component. The first direction X is as follows... Figure 2 As indicated by the arrow.

[0070] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the cooling and lubrication system includes a seal 8, and the water inlet channel 102 includes a first end 1021 and a second end 1022. The seal 8 seals the first end 1021, and the orientation of the first end 1021 is different from that of the second end 1022. The controller 3 has a third end 301, and the third end 301 and the second end 1022 are located on the same side of the gearbox housing 1 and are connected.

[0071] Understandably, since the water inlet channel 102 is generally formed through the gearbox housing 1, a channel for the core forming the water inlet channel 102 to detach from the gearbox housing 1 is required during casting. The orientation of the first end 1021 is different from that of the second end 1022, which is beneficial for the introduction of coolant into the second end 1022 and also for the core to detach from the water inlet channel 102 through the first end 1021. The third end 301 can be connected to the second end 1022 through a flexible hose. The third end 301 and the second end 1022 are located on the same side of the gearbox housing 1 and are connected, which reduces the need for the hose to be twisted when connecting the third end 301 and the second end 1022, and helps to improve the stability of the connection between the second end 1022 and the third end 301.

[0072] In this embodiment, the third end 301, the second end 1022 and the oil outlet pipe 4 are located on the same side of the gearbox housing 1. This facilitates the arrangement of the hose connecting the third end 301 and the second end 1022 and also improves the convenience of assembly.

[0073] In some embodiments of this application, such as Figure 2 As shown, the water inlet channel 102 penetrates the gearbox housing 1 along the first direction X. The water inlet channel 102 has a fourth end 1023. The first end 1021 and the fourth end 1023 are located at both ends of the water inlet channel 102 along the first direction X, and the second end 1022 is located on one side of the water inlet channel 102.

[0074] It is understandable that the space between the first end 1021 and the fourth end 1023 can be formed during casting by placing a core. The water inlet channel 102 penetrates through the gearbox housing 1, which is beneficial for direct formation during casting and reduces subsequent processing and finishing procedures. The second end 1022 is located on one side of the water inlet channel 102 and can be formed by arranging a core.

[0075] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, along the extension direction of the oil outlet pipe 4, the oil outlet pipe 4 has a second oil outlet 401, a third oil outlet 402, a fourth oil outlet 403 and an inlet 404. The second oil outlet 401, the third oil outlet 402 and the fourth oil outlet 403 are respectively connected to the receiving cavity 101, and the inlet 404 is connected to the first oil outlet of the heat exchange unit 2.

[0076] It is understandable that the inlet 404 is connected to the first oil outlet of the heat exchange unit 2, which allows the heat exchange unit 2 to introduce lubricating oil into the oil outlet pipe 4. The second oil outlet 401, the third oil outlet 402 and the fourth oil outlet 403 are respectively connected to the receiving cavity 101, which can introduce lubricating oil into different positions of the receiving cavity 101, thereby lubricating and cooling the various components located in the receiving cavity 101, which helps to improve the efficiency of lubrication and cooling.

[0077] In this embodiment of the application, the gearbox housing 1 may have openings that correspond one-to-one with the second oil outlet 401, the third oil outlet 402 and the fourth oil outlet 403. The openings can guide lubricating oil into the receiving cavity 101 to achieve the functions of lubrication and cooling.

[0078] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the cooling and lubrication system includes a differential 5, which is located in the housing cavity 101, and the second oil outlet 401 of the oil outlet pipe faces the differential 5.

[0079] Understandably, the second oil outlet 401 facing the differential 5 allows the lubricating oil, guided by the oil outlet pipe 4, to flow towards the differential 5 and lubricate it. This helps improve the lubrication and cooling efficiency of the differential 5.

[0080] In some embodiments of this application, the cooling and lubrication system includes a motor shaft 6, with a third oil outlet 402 located at one end of the motor shaft 6 and facing the motor shaft 6.

[0081] Understandably, the third oil outlet 402 facing the motor shaft 6 allows lubricating oil to flow towards the motor shaft 6 under the guidance of the oil outlet pipe 4, thus lubricating the motor shaft 6. This helps to improve the lubrication efficiency of the motor shaft 6.

[0082] In this embodiment, the motor shaft 6 can be a hollow structure, and the lubricating oil passes through the hollow part of the motor shaft 6, which can play a cooling role.

[0083] In this embodiment of the application, the motor shaft 6 and the side wall of the receiving cavity 101 can be connected by a bearing, and the bearing is located at the end where the third oil outlet 402 of the motor shaft 6 is located.

[0084] In some embodiments of this application, the cooling and lubrication system includes an output shaft 7, with a fourth oil outlet 403 located at one end of the output shaft 7 and facing the output shaft 7.

[0085] Understandably, the fourth oil outlet 403 facing the output shaft 7 allows lubricating oil to flow towards the output shaft 7 under the guidance of the oil outlet pipe 4, thus lubricating the output shaft 7. This helps to improve the lubrication efficiency of the output shaft 7.

[0086] In this embodiment, the output shaft 7 can be a hollow structure, and the lubricating oil passes through the hollow part of the output shaft 7, which can play a cooling role.

[0087] In this embodiment of the application, the output shaft 7 and the side wall of the receiving cavity 101 can be connected by a bearing, and the bearing is located at the end where the third oil outlet 402 of the output shaft 7 is located.

[0088] In this embodiment of the application, the cooling and lubrication system includes a differential 5, which is located in the receiving cavity 101, and a second oil outlet 401 facing the differential 5. The cooling and lubrication system also includes a motor shaft 6, and a third oil outlet 402 is located at one end of the motor shaft 6 and faces the motor shaft 6.

[0089] In this embodiment of the application, the cooling and lubrication system includes a differential 5, which is located in the receiving cavity 101. The second oil outlet 401 faces the differential 5. The cooling and lubrication system includes an output shaft 7, and a fourth oil outlet 403 is located at one end of the output shaft 7 and faces the output shaft 7.

[0090] In this embodiment of the application, the cooling and lubrication system includes a motor shaft 6, a third oil outlet 402 located at one end of the motor shaft 6 and facing the motor shaft 6, and an output shaft 7, a fourth oil outlet 403 located at one end of the output shaft 7 and facing the output shaft 7.

[0091] In some embodiments of this application, the cooling and lubrication system includes a differential 5 located within a housing cavity 101, a second oil outlet 401 facing the differential 5, a motor shaft 6, a third oil outlet 402 located at one end of the motor shaft 6 and facing the motor shaft 6, and an output shaft 7, a fourth oil outlet 403 located at one end of the output shaft 7 and facing the output shaft 7.

[0092] In this embodiment, the motor shaft 6, the output shaft 7, and the differential 5 are sequentially connected in a transmission manner, and the water inlet channel 102 and the water outlet channel 103 are both located on the opposite side of the output shaft 7 on the differential 5.

[0093] In this embodiment, the motor shaft 6 and the output shaft 7 are driven by gear meshing, and the output shaft 7 and the differential 5 are driven by gear meshing.

[0094] In this embodiment, the gearbox housing 1 has an opening through which the half shaft passes, which facilitates the transmission connection between the half shaft and the differential 5.

[0095] In some embodiments of this application, the diameter of the inlet 404 is larger than the diameter of the third oil outlet 402, the diameter of the third oil outlet 402 is larger than the diameter of the fourth oil outlet 403, and the diameter of the fourth oil outlet 403 is larger than the diameter of the second oil outlet 401.

[0096] Understandably, the flow rate at inlet 404 needs to be greater than the sum of the flow rates at the second outlet 401, the third outlet 402, and the fourth outlet 403. Therefore, setting the diameter of inlet 404 to the maximum is beneficial for providing sufficient lubricating oil to the second outlet 401, the third outlet 402, and the fourth outlet 403. The output shaft 7 generates a significant amount of heat during operation and serves to transmit power from the motor shaft 6 to the differential 5; therefore, the diameter of the fourth outlet 403 is larger than that of the second outlet 401. Since the motor shaft 6 generates heat through magnetoelectric effects, resulting in substantial heat output, the diameter of the third outlet 402 is larger than that of the fourth outlet 403. By rationally setting the diameters of each outlet on the oil pipe 4, the distribution of lubricating oil can be improved, along with the accuracy of lubrication and cooling.

[0097] In this embodiment of the application, the diameter of the second oil outlet 401 is in the range of 1 to 1.4 mm, wherein the value can be selected as 1 mm, 1.1 mm, 1.2 mm, 1.3 mm or 1.4 mm, or other values ​​from 1 to 1.4 mm.

[0098] In this embodiment of the application, the diameter of the fourth oil outlet 403 is in the range of 1.4 to 1.6 mm, wherein the value can be 1.4 mm, 1.5 mm or 1.6 mm, or other values ​​in the range of 1.4 to 1.6 mm.

[0099] In this embodiment of the application, the diameter of the third oil outlet 402 ranges from 2 to 4 mm, and can be selected as 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm or 4 mm, or other values ​​from 2 to 4 mm.

[0100] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the oil outlet pipe 4 includes a first section 41 and a second section 42. The first section 41 and the second section 42 are connected and form an angle. The oil outlet pipe 4 has a fifth oil outlet 405. The second oil outlet 401 and the fourth oil outlet 403 are both located in the first section 41. The third oil outlet 402 and the fifth oil outlet 405 are both located in the second section 42. The first section 41 is connected to the oil outlet of the heat exchange unit 2.

[0101] Understandably, the fifth oil outlet 405 can be connected to the receiving cavity 101 to guide excess lubricating oil from the oil outlet pipe 4 into the receiving cavity 101, so that the lubricating oil enters the bottom of the receiving cavity 101 under the action of gravity.

[0102] In some embodiments of this application, the gearbox housing 1 includes a housing 11 and a cover plate 12. The housing 11 has a receiving cavity 101, and the cover plate 12 covers the opening of the receiving cavity 101. The oil outlet pipe 4 communicates with the receiving cavity 101 via the cover plate 12.

[0103] It is understandable that the casing 11 is generally formed by casting. The diameters of the first oil outlet, the second oil outlet 401, the third oil outlet 402, and the fourth oil outlet 403 are generally small, which is not conducive to forming openings for the oil outlets during the casting process by increasing the mold size. At the same time, opening additional openings for lubricating oil to pass through after casting can easily compromise the structural strength of the casing 11. Therefore, by providing a cover plate 12 to connect the first oil outlet, the second oil outlet 401, the third oil outlet 402, and the fourth oil outlet 403 to the receiving cavity 101, it is beneficial to maintain the strength of the casing 11 itself.

[0104] In this embodiment, the cover plate 12 and the housing 11 are connected by bolts.

[0105] In some embodiments of this application, such as Figure 7 As shown, the cooling and lubrication system includes an oil pump, which is connected to the oil inlet of the heat exchange unit 2.

[0106] Understandably, the oil pump can drive the lubricating oil, which in turn drives the lubricating oil into the heat exchange unit 2 and the oil outlet pipe 4.

[0107] In this embodiment, the oil pump can be connected to the heat exchange unit 2 via a filter element.

[0108] A second aspect of this application provides an automobile that includes a cooling and lubrication system as described in the above embodiments.

[0109] It is understood that the automobile of this application has the same technical effects as the above embodiments due to the use of the cooling and lubrication system described above, and will not be repeated here.

[0110] In the embodiments of this application, the vehicle can be a pure electric vehicle, a hybrid vehicle with an engine and an electric motor as power sources, or a hybrid vehicle formed by combining other power sources with an electric motor.

[0111] In this embodiment of the application, the car includes wheels, and the water inlet channel 102 and the water outlet channel 103 are located on the side of the gearbox housing 1 near the wheels.

[0112] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0113] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.

The scope of this application is limited only by the appended claims.
