Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following is for reference. Figures 1-6 The present invention describes a hybrid module 10 for a vehicle according to an embodiment of the present invention, and a vehicle having therein.

[0021] like Figures 1-3 As shown, the hybrid module 10 of the vehicle according to an embodiment of the present utility model includes: an engine 1, a drive motor 2, a planetary gear set 3, a power output shaft 4, and an oil pump drive shaft 5.

[0022] Among them, engine 1 can provide driving force, and the power of engine 1 can be transmitted to power output shaft 4 and oil pump drive shaft 5 through planetary gear set 3. Drive motor 2 can provide driving force, and the power of drive motor 2 can be transmitted to power output shaft 4 and oil pump drive shaft 5 through planetary gear set 3. Engine 1 and drive motor 2 can achieve power output independently or achieve hybrid power output.

[0023] As some embodiments of this application, the rear end of the power output shaft 4 can be connected to a reduction gear, and the power from the power output shaft 4 can be transmitted to the reduction gear. The rear end of the oil pump drive shaft 5 can be connected to an oil pump connecting device 6, and the rear end of the oil pump connecting device 6 can be connected to an oil pump. The power from the oil pump drive shaft 5 can be transmitted to the oil pump connecting device 6, thereby driving the oil pump to work. The planetary gear set 3 is connected between the power input end (engine 1, drive motor 2) and the power output end (power output shaft 4, oil pump drive shaft 5). The planetary gear set 3 can be used to change the power output path so that the power from the engine 1 and / or drive motor 2 can be transmitted uninterruptedly to the power output shaft 4 and oil pump drive shaft 5 to drive the oil pump to work, and at the same time, it can transmit power to the reduction gear to drive the vehicle to move.

[0024] As some embodiments of this application, the planetary gear set 3 can be constructed as a double planetary gear set 3, which has a compact structure, saves layout space, and improves transmission efficiency.

[0025] Specifically, engine 1 is either driven or selectively engaged with the planet carrier 32 of planetary gear set 3, that is, as... Figure 3 As shown, the engine 1 and the planetary carrier 32 can be directly connected by transmission. As some embodiments of this application, the engine 1 and the planetary carrier 32 can be connected by transmission through, but not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc., so that the power of the engine 1 can be directly transmitted to the planetary carrier 32. Alternatively, as... Figure 1 and Figure 2 As shown, the engine 1 and the planetary carrier 32 can be selectively connected by a coupling / disengagement device, which can be a clutch, a coupling, etc. When the coupling / disengagement device is engaged, the power of the engine 1 can be transmitted to the planetary carrier 32. When it is not necessary to transmit the power of the engine 1 to the planetary carrier 32, the coupling / disengagement device is disengaged to reduce dragging losses.

[0026] The drive motor 2 is either selectively or continuously connected to the sun gear 31 of the planetary gear set 3, meaning that, for example... Figure 1 and Figure 2As shown, the drive motor 2 and the sun gear 31 can be directly connected for transmission. In some embodiments of this application, the drive motor 2 and the sun gear 31 can be connected for transmission through, but not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc., so that the power of the drive motor 2 can be directly transmitted to the sun gear 31. Alternatively, as... Figure 3 As shown, the drive motor 2 and the sun gear 31 can be selectively connected by a coupling / disengagement device, which can be a clutch, a coupling, etc. When the coupling / disengagement device is engaged, the power of the drive motor 2 can be transmitted to the sun gear 31. When it is not necessary to transmit the power of the drive motor 2 to the sun gear 31, the coupling / disengagement device is disengaged to reduce dragging losses.

[0027] like Figures 1-3 As shown, the power output shaft 4 is connected to the gear ring 34 of the planetary gear set 3. In some embodiments of this application, the power output shaft 4 and the gear ring 34 can be connected by, but not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc. The oil pump drive shaft 5 is connected to the planetary carrier 32. In some embodiments of this application, the oil pump drive shaft 5 and the planetary carrier 32 can be connected by, but not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc.

[0028] As some embodiments of this application, such as Figure 1 As shown, the planet carrier 32 and the sun gear 31 can be selectively engaged. The planet carrier 32 and the sun gear 31 can be selectively connected by a engagement / disengagement device, which can be a clutch, a coupling, etc. When the engagement / disengagement device is engaged, the planet carrier 32 and the sun gear 31 can transmit power. When power transmission is not required, the engagement / disengagement device is disengaged.

[0029] As some embodiments of this application, such as Figure 2 and Figure 3 As shown, the planetary carrier 32 and the gear ring 34 can be selectively engaged. The planetary carrier 32 and the gear ring 34 can be selectively connected by a engagement and disengagement device, which can be a clutch, a coupling, etc. When the engagement and disengagement device is engaged, the planetary carrier 32 and the gear ring 34 can transmit power. When power transmission is not required, the engagement and disengagement device is disengaged.

[0030] Based on the transmission connection method described above, this application provides multiple power transmission paths. Taking the first transmission path as an example, such as... Figure 1 As shown, in the first transmission path, the engine 1 is selectively engaged with the planet carrier 32 of the planetary gear set 3, the drive motor 2 is drivenly connected to the sun gear 31 of the planetary gear set 3, the power output shaft 4 is drivenly connected to the ring gear 34 of the planetary gear set 3, the oil pump drive shaft 5 is drivenly connected to the planet carrier 32, and the planet carrier 32 is selectively engaged with the sun gear 31.

[0031] like Figure 1 As shown, for the first transmission path, there can be multiple power transmission modes: engine direct drive mode, electric motor direct drive mode, first hybrid mode, second hybrid mode, etc., and driving range extension mode.

[0032] In engine direct drive mode, engine 1 is engaged with planetary carrier 32, and planetary carrier 32 is engaged with sun gear 31. Engine 1 operates, while drive motor 2 does not. Engine 1 outputs power, which can be sequentially transmitted to planetary carrier 32 and oil pump drive shaft 5, thereby driving the oil pump. The power of engine 1 can also be sequentially transmitted to ring gear 34 and power output shaft 4 to drive the vehicle. Because planetary carrier 32 is engaged with sun gear 31, and planetary gear set 3 is integrally fixed, the power of engine 1 can be evenly distributed to oil pump drive shaft 5 and power output shaft 4.

[0033] In the direct drive mode, engine 1 is not engaged with planetary carrier 32, while planetary carrier 32 is engaged with sun gear 31. Engine 1 is not working, but drive motor 2 is working. Drive motor 2 outputs power, which can be transmitted to planetary gear set 3 and then output as a whole to oil pump drive shaft 5 and power output shaft 4.

[0034] In the first hybrid mode (e-CVT mode), engine 1 is engaged with planetary carrier 32, while planetary carrier 32 is not engaged with sun gear 31. Engine 1 operates, and drive motor 2 operates. Both engine 1 and drive motor 2 can output power. The power from engine 1 can be transmitted to planetary carrier 32, and the power from drive motor 2 can be transmitted to sun gear 31. The two power sources can be continuously variable transmission (CVT) via planetary gear set 3 and output to power output shaft 4 via ring gear 34. At the same time, the power from engine 1 can be output to oil pump drive shaft 5 via planetary carrier 32, so as to achieve the effect of simultaneously driving oil pump and vehicle movement, and can increase the power output efficiency of power output shaft 4.

[0035] In the second hybrid mode, engine 1 is connected to planetary carrier 32, and planetary carrier 32 is connected to sun gear 31. Engine 1 operates, and drive motor 2 operates. Both engine 1 and drive motor 2 output power. At this time, planetary gear set 3 is fixedly connected, and the power of engine 1 and drive motor 2 can be output as a whole to oil pump drive shaft 5 and power output shaft 4.

[0036] In range-extending mode, engine 1 engages with planetary carrier 32, while planetary carrier 32 is not engaged with sun gear 31. Engine 1 operates, and drive motor 2 generates electricity. Part of the power output from engine 1 is transmitted to drive shaft 4, and part is transmitted to drive motor 2, enabling drive motor 2 to generate electricity.

[0037] It is understandable that the architecture design of this application can have multiple working modes. The connection method of power input can be changed without changing the position of the oil pump, so as to achieve no power interruption of the oil pump in multiple scenarios. At the same time, in the power split mode, the power of the engine 1 can be directly connected to the oil pump through other components (drive motor 2, clutch, planetary gear set 3, etc.), which is ingenious.

[0038] In addition to the first transmission path, this application also includes multiple power transmission paths, such as Figure 3 As shown, in the second transmission path, engine 1 is connected to planetary carrier 32, drive motor 2 is selectively engaged with sun gear 31, power output shaft 4 is connected to the ring gear 34 of planetary gear set 3, oil pump drive shaft 5 is connected to planetary carrier 32, and planetary carrier 32 is selectively engaged with ring gear 34.

[0039] Or, such as Figure 4 As shown, in the third transmission path, engine 1 is selectively engaged with planetary carrier 32, drive motor 2 is drivenly connected to sun gear 31, power output shaft 4 is drivenly connected to ring gear 34, oil pump drive shaft 5 is drivenly connected to planetary carrier 32, and planetary carrier 32 is selectively engaged with sun gear 31. Other types of transmission paths will not be described in detail.

[0040] Therefore, the hybrid module 10 proposed in this application can drive the oil pump drive shaft 5 to rotate through the engine 1 and / or drive motor 2 in various modes, thereby achieving the effect of no power interruption of the oil pump in multiple scenarios. Moreover, the hybrid module 10 proposed in this application has multiple architectures and can be adapted to multiple transmissions, with wide adaptability.

[0041] In some embodiments of this application, such as Figure 1 As shown, the oil pump drive shaft 5 is loosely fitted onto the power output shaft 4 and is coaxially arranged with the power output shaft 4. The coaxial arrangement design can make the structural layout more compact, save space, make the architecture more reasonable, facilitate the coordinated arrangement with other components, and facilitate the miniaturization design of the hybrid module 10, which is convenient for the arrangement of other vehicle assemblies.

[0042] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the engine 1 can be selectively engaged with the planetary carrier 32. The engine 1 and the planetary carrier 32 can be selectively connected by a engagement / disengagement device, which can be a clutch, a coupling, etc. When the engagement / disengagement device is engaged, the power of the engine 1 can be transmitted to the planetary carrier 32. When it is not necessary to transmit the power of the engine 1 to the planetary carrier 32, the engagement / disengagement device is disengaged to reduce drag losses.

[0043] Furthermore, the drive motor 2 is connected to the sun gear 31 through a transmission connection. The drive motor 2 and the sun gear 31 can be directly connected through a transmission connection. As some embodiments of this application, the drive motor 2 and the sun gear 31 can be connected through a transmission connection, but not limited to a direct connection, a coupling connection, a gear pair connection, a spline connection, etc. The power of the drive motor 2 can be directly transmitted to the sun gear 31.

[0044] In some embodiments of this application, such as Figure 3 As shown, engine 1 is connected to planetary carrier 32 via a transmission connection. Engine 1 and planetary carrier 32 can be directly connected via a transmission connection. In some embodiments of this application, engine 1 and planetary carrier 32 can be connected via, but are not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc., allowing the power of engine 1 to be directly transmitted to planetary carrier 32. Drive motor 2 is selectively engaged with sun gear 31. Drive motor 2 and sun gear 31 can be selectively connected via a engagement / disengagement device, such as a clutch or a coupling. When the engagement / disengagement device is engaged, the power of drive motor 2 can be transmitted to sun gear 31. When it is not necessary to transmit the power of drive motor 2 to sun gear 31, the engagement / disengagement device disengages to reduce drag losses.

[0045] Therefore, this configuration allows one of the engine 1 and drive motor 2 to be connected to the planetary gear set 3, and allows one of the engine 1 and drive motor 2 to be selectively engaged with the planetary gear set 3. This can reduce to some extent the drag loss and reduce the number of engagement and disengagement devices, thus balancing performance and cost and improving the rationality of the hybrid module 10's architecture.

[0046] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the hybrid module 10 of the vehicle also includes a first coupling device 71. The first coupling device 71 can be the coupling and disengagement device in the above embodiment. The first coupling device 71 can have two working states: coupling and disengagement. When the first coupling device 71 is coupled, it can transmit power. When the first coupling device 71 is disengaged, the power transmission path is broken.

[0047] like Figure 1 and Figure 2 As shown, the first coupling device 71 can be connected between the engine 1 and the planetary carrier 32 to selectively engage the engine 1 and the planetary carrier 32. When the first coupling device 71 is engaged, the power of the engine 1 can be transmitted to the planetary carrier 32, and then to the oil pump drive shaft 5. Or, as... Figure 3As shown, the first coupling device 71 can be connected between the drive motor 2 and the sun gear 31 to selectively engage the drive motor 2 and the sun gear 31. When the first coupling device 71 is engaged, the power of the drive motor 2 can be transmitted to the sun gear 31, and then transmitted to the oil pump drive shaft 5 through the planetary gear 33 and the planet carrier 32, so as to achieve the effect of no power interruption of the oil pump in multiple scenarios, so as to meet the related needs of cooling, lubrication, shifting, etc., and improve the reliability of the vehicle.

[0048] As some embodiments of this application, the first engagement device 71 may be constructed as, but is not limited to, an electromagnetic clutch, a magnetic powder clutch, a friction clutch, a hydraulic clutch, etc. Of course, the first engagement device 71 may also be constructed as other types of clutches. It is understood that the specific type of the first engagement device 71 can be selected according to actual needs, and this application does not limit it in this regard.

[0049] In some embodiments of this application, such as Figure 1 As shown, along the axial direction of the power output shaft 4, the first coupling device 71 can be located between the engine 1 and the drive motor 2. This arrangement is compact, saves space, and improves space utilization.

[0050] In some embodiments of this application, such as Figure 1 As shown, the hybrid module 10 of the vehicle also includes a second coupling device 72. The second coupling device 72 can be the coupling and disengagement device in the above embodiment. The second coupling device 72 can have two working states: coupling and disengagement. When the second coupling device 72 is coupled, it can transmit power. When the second coupling device 72 is disengaged, the power transmission path is broken.

[0051] The second engagement device 72 can be connected between the planet carrier 32 and the sun gear 31 to selectively engage the planet carrier 32 and the sun gear 31. When the second engagement device 72 is engaged, the planetary gear set 3 is locked. Alternatively, the second engagement device 72 can be connected between the planet carrier 32 and the ring gear 34 to selectively engage the planet carrier 32 and the ring gear 34. When the second engagement device 72 is engaged, the planetary gear set 3 is locked. By setting the second engagement device 72, the locking of the planetary gear set 3 can be controlled, thereby meeting the power transmission requirements in various scenarios and improving the rationality and applicability of the hybrid module 10 architecture.

[0052] In some embodiments of this application, the hybrid module 10 of the vehicle further includes: a connecting support 8, the rotor of the drive motor 2 is connected to the connecting support 8 in a transmission manner, the connecting support 8 is connected to or selectively coupled to the sun gear 31 in a transmission manner, and the rotor is located on the radial outer side of the sun gear 31.

[0053] Among them, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the rotor of the drive motor 2 can be driven to the connecting support member 8. In some embodiments of this application, the rotor and the connecting support member 8 can be driven to each other via, but are not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc. The connecting support member 8 can be driven to the sun gear 31. In some embodiments of this application, the sun gear 31 and the connecting support member 8 can be driven to each other via, but are not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc. The power of the drive motor 2 is transmitted through the rotor to the connecting support member 8, then to the sun gear 31, and finally through the planetary gears 33 and planet carrier 32 to the oil pump drive shaft 5, thereby achieving the effect of driving the oil pump.

[0054] like Figure 3 and Figure 6 As shown, the rotor of the drive motor 2 can be driven to the connecting support member 8. The connecting support member 8 can be selectively engaged with the sun gear 31. The connecting support member 8 and the sun gear 31 can be selectively engaged by a coupling or a clutch. When the coupling or clutch is engaged, the connecting support member 8 and the sun gear 31 are driven to the sun gear 31. The power of the drive motor 2 can be transmitted sequentially to the connecting support member 8, the sun gear 31, the planetary gear 33, and the planet carrier 32, and then to the oil pump drive shaft 5 to achieve the effect of driving the oil pump.

[0055] The connecting support 8 can connect the rotor and the sun gear 31 and can be supported between the rotor and the sun gear 31 to improve the structural stability of the hybrid module 10. Furthermore, the rotor can be located on the radial outer side of the sun gear 31. This configuration is reasonable, the transmission path is short, and the power transmission efficiency can be improved.

[0056] In some embodiments of this application, the hybrid module 10 of the vehicle further includes: a first connecting shaft 91, a sun gear 31 mounted on the first connecting shaft 91, a drive motor 2 connected to or selectively coupled to the first connecting shaft 91, and the first connecting shaft 91 being loosely fitted onto the oil pump drive shaft 5 and coaxially arranged with the oil pump drive shaft 5.

[0057] Among them, such as Figure 4 and Figure 5 As shown, the sun gear 31 can be mounted on the first connecting shaft 91. In some embodiments of this application, the sun gear 31 can be integrally formed with the first connecting shaft 91, or connected by a spline, etc. The drive motor 2 can be connected to the first connecting shaft 91 for transmission. In some embodiments of this application, the drive motor 2 and the first connecting shaft 91 can be connected for transmission through, but not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc., and the power of the drive motor 2 can be transmitted to the first connecting shaft 91.

[0058] like Figure 6As shown, the sun gear 31 can be driven to the first connecting shaft 91, and the drive motor 2 can be selectively engaged with the first connecting shaft 91. The drive motor 2 can be selectively engaged with the first connecting shaft 91 through a coupling or a clutch. When the coupling or clutch is engaged, the drive motor 2 is driven to the first connecting shaft 91, and the power of the drive motor 2 can be transmitted to the planetary gear set 3 through the first connecting shaft 91, and then to the oil pump drive shaft 5, so as to achieve the effect of driving the oil pump to work.

[0059] Furthermore, the first connecting shaft 91 can be loosely fitted onto the oil pump drive shaft 5 and coaxially arranged with the oil pump drive shaft 5.

[0060] This design is reasonable and compact, which helps save space and facilitates the arrangement of planetary carrier 32, thus reducing the difficulty of arranging planetary row 3.

[0061] In some embodiments of this application, such as Figure 1 As shown, the hybrid module 10 of the vehicle also includes: a first connecting shaft 91 and a second connecting shaft 92. The sun gear 31 can be installed on the first connecting shaft 91. As some embodiments of this application, the sun gear 31 can be integrally formed with the first connecting shaft 91, splined connection, etc.

[0062] The drive motor 2 is either driven or selectively connected to the first connecting shaft 91. In other words, the drive motor 2 can be driven to the first connecting shaft 91. As some embodiments of this application, the drive motor 2 and the first connecting shaft 91 can be driven to each other by means of, but not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc. Alternatively, the drive motor 2 can be selectively connected to the first connecting shaft 91. As some embodiments of this application, the drive motor 2 can be selectively connected to the first connecting shaft 91 by means of a coupling or clutch. When the coupling or clutch is engaged, the power of the drive motor 2 can be transmitted to the first connecting shaft 91.

[0063] The second connecting shaft 92 can be connected to the planetary carrier 32 for transmission. As some embodiments of this application, the second connecting shaft 92 and the planetary carrier 32 can be connected for transmission by means of, but not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc.

[0064] The second connecting shaft 92 is either driven or selectively connected to the engine 1. In other words, the second connecting shaft 92 can be driven to the engine 1. As some embodiments of this application, the second connecting shaft 92 and the engine 1 can be driven to each other by means of, but not limited to, direct connection, coupling connection, gear pair connection, spline connection, etc. Alternatively, the second connecting shaft 92 can be selectively connected to the engine 1. The second connecting shaft 92 and the engine 1 can be selectively connected by a coupling or a clutch. When the coupling or clutch is engaged, the power of the engine 1 can be transmitted to the first connecting shaft 91.

[0065] In addition, the first connecting shaft 91 can be loosely fitted onto the second connecting shaft 92 and is coaxially arranged with the second connecting shaft 92.

[0066] This design is reasonable and compact, which helps save space and facilitates the arrangement of planetary carrier 32, thus reducing the difficulty of arranging planetary row 3.

[0067] The hybrid module 10 proposed in this application can achieve the effect of no power interruption of the oil pump in multiple scenarios without changing the original position of the oil pump. Moreover, the hybrid module 10 proposed in this application has multiple architectures and can be adapted to multiple transmissions, with wide adaptability.
