[0050] In the description of the present invention, "multiple" means two or more, and "several" means one or more.

[0051] A hybrid power system 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0052] like Figure 1-Figure 12 As shown, the hybrid power system 1 according to the embodiment of the present invention includes an engine 100 , an output shaft 200 , a gear pair and a drive motor 300 .

[0053] The output shaft 200 is used to output power to the wheels. The gear pair includes a first driving gear 510 and a first driven gear 520 that mesh with each other. The engine 100 is selectively connected to the first driving gear 510. The first driven gear 520 is provided on the output shaft 200 and is connected to the output shaft 200. The drive motor 300 is provided with an output gear 320. The output gear 320 is connected to the drive motor shaft 310, and the output gear 320 is meshed with the first driven gear 520 to output power to the output shaft 200 through the output gear 320 and the first driven gear 520.

[0054] The engine 100 is selectively connected to the first driving gear 510 in transmission mode, which means that the engine 100 can be connected to the first driving gear 510 in transmission mode, or the power transmission between the engine 100 and the first driving gear 510 can be disconnected.

[0055] According to the hybrid power system 1 of the embodiment of the utility model, the engine 100 is selectively connected to the first driving gear 510, and the output gear 320 of the drive motor 300 is connected to the drive motor shaft 310. In this way, when the engine 100 is disconnected from the first driving gear 510, the drive motor 300 can be used to drive the vehicle alone; or, when the engine 100 is connected to the first driving gear 510, the engine 100 can be used to drive the vehicle alone, or the engine 100 and the drive motor 300 can be used to drive the vehicle together.

[0056] In addition, the engine 100 is selectively connected to the first driving gear 510 by meshing the first driving gear 510 and the first driven gear 520, and the first driven gear 520 is disposed on the output shaft 200 and is connected to the output shaft 200. In this way, when the engine 100 is connected to the first driving gear 510, the engine 100 can output power to the output shaft 200 through the first driving gear 510 and the first driven gear 520.

[0057] Furthermore, the output gear 320 is transmission-connected with the drive motor shaft 310, and the output gear 320 is meshed with the first driven gear 520. In this way, the drive motor 300 can output power to the output shaft 200 through the output gear 320 and the first driven gear 520, and the output gear 320 and the first driven gear 520 can reduce the power of the drive end motor for transmission, with high transmission efficiency and good economy.

[0058] That is to say, both the first driving gear 510 and the output gear 320 can output power to the output shaft 200 through the first driven gear 520, that is, the gear through which the first driving gear 510 outputs power to the output shaft 200 and the gear through which the output gear 320 outputs power to the output shaft 200 can be the same gear. This arrangement is conducive to reducing the number of gears in the hybrid power system 1, and further can reduce the number of parts, which is conducive to cost saving. Moreover, the number of gears sleeved on the output shaft 200 is reduced, and the axial length of the output shaft 200 can also be shortened accordingly, and the space utilization rate is higher, so that the structure of the hybrid power system 1 can be set more compactly.

[0059] In addition, it can be understood that when the engine 100 stops working or the vehicle is not needed to be driven by the engine 100, the engine 100 is disconnected from the first driving gear 510, that is, there is no power transmission between the engine 100 and the first driven gear 520, and the engine 100 will not affect the rotation of the first driven gear 520, thereby not affecting the drive motor 300 to output power to the output shaft 200 through the output gear 320 and the first driven gear 520, and the structural setting is more reasonable.

[0060] Thus, the output gear 320 and the first driving gear 510 of the hybrid system 1 according to the embodiment of the utility model can both output power to the output shaft 200 through the first driven gear 520, thereby reducing the number of gears and having the advantages of fewer parts, low cost and compact structure.

[0061] In some specific embodiments of the present invention, Figure 1 As shown, the output gear 320 and the first driving gear 510 are respectively arranged on opposite radial sides of the first driven gear 520. In this way, the output gear 320 and the first driving gear 510 will not interfere with each other, and the first driven gear 520 is easy to mesh with the first driving gear 510 and the output gear 320 at the same time, and the structural arrangement is more reasonable.

[0062] In some specific embodiments of the present invention, Figure 1 As shown, the hybrid system 1 further includes an intermediate shaft 400 .

[0063] Specifically, the engine 100 is transmission-connected to the intermediate shaft 400 , and the first driving gear 510 is disposed on the intermediate shaft 400 . The intermediate shaft 400 outputs power to the output shaft 200 through a gear pair.

[0064] Among them, the engine 100 can be arranged on the radial side of the intermediate shaft 400 and be transmission-connected to the intermediate shaft 400, so that the size of the hybrid power system 1 along the axial direction of the intermediate shaft 400 can be reduced; or, the engine 100 can be arranged at one axial end of the intermediate shaft 400 and be transmission-connected to the intermediate shaft 400, so that the size of the hybrid power system 1 along the radial direction of the intermediate shaft 400 can be reduced.

[0065] By providing the intermediate shaft 400 , the arrangement of the gear pairs can be more diversified, that is, the arrangement of the hybrid power system 1 can be more diversified, which is conducive to optimizing the spatial arrangement of the hybrid power system 1 .

[0066] In some specific embodiments of the present invention, Figure 1 As shown, the hybrid system 1 further includes a clutch.

[0067] The clutch is disposed on the intermediate shaft 400 and / or the output shaft 200 , and the clutch connects or disconnects the intermediate shaft 400 and / or the output shaft 200 with the gear pair, so that the intermediate shaft 400 is selectively transmission-connected with the output shaft 200 through the gear pair.

[0068] For example, the clutch may be disposed on the intermediate shaft 400 , or the clutch may be disposed on the output shaft 200 , or the clutch may be disposed on both the intermediate shaft 400 and the output shaft 200 .

[0069] With such arrangement, when the clutch is engaged, the intermediate shaft 400 can transmit power to the output shaft 200 through the gear pair, and at this time the engine 100 can transmit power to the output shaft 200; and when the clutch is disengaged, the intermediate shaft 400 can disconnect the power transmission with the output shaft 200, and at this time the engine 100 can disconnect the power transmission with the output shaft 200.

[0070] In some specific embodiments of the present invention, Figure 1 As shown, there are a plurality of gear pairs, and the plurality of gear pairs include a first gear position gear pair 500 and a second gear position gear pair 600 .

[0071] The first gear pair 500 includes a first driving gear 510 and a first driven gear 520 . The second gear pair 600 includes a second driving gear 610 and a second driven gear 620 . The second driving gear 610 is disposed on the intermediate shaft 400 , and the second driven gear 620 is disposed on the output shaft 200 .

[0072] The clutch connects or disconnects the intermediate shaft 400 with the first driving gear 510, and the clutch connects or disconnects the intermediate shaft 400 and / or the output shaft 200 with the second gear gear pair 600, so that the intermediate shaft 400 selectively outputs power to the output shaft 200 through the first gear gear pair 500 or the second gear gear pair 600.

[0073] The transmission ratios of the first gear gear pair 500 and the second gear gear pair 600 are different.

[0074] For example, the transmission ratio of the first driving gear 510 and the first driven gear 520 can be greater than the transmission ratio of the second driving gear 610 and the second driven gear 620, so that the torque of the power output from the intermediate shaft 400 to the output shaft 200 through the first gear gear pair 500 can be greater than the torque of the power output from the intermediate shaft 400 to the output shaft 200 through the second gear gear pair 600.

[0075] Among them, the clutch connects or disconnects the intermediate shaft 400 and / or the output shaft 200 with the second gear gear pair 600, which means that the clutch can control the connection or disconnection of the intermediate shaft 400 with the second gear gear pair 600, for example, the clutch can control the connection or disconnection of the intermediate shaft 400 with the second driving gear 610; or, the clutch can control the connection or disconnection of the output shaft 200 with the second gear gear pair 600, for example, the clutch can control the connection or disconnection of the output shaft 200 with the second driven gear 620.

[0076] Specifically, when the clutch connects the intermediate shaft 400 with the first driving gear 510, the engine 100 can output power to the output shaft 200 through the first gear pair 500, and when the clutch connects the intermediate shaft 400 with the second driving gear 610, or the clutch connects the output shaft 200 with the second driven gear 620, the engine 100 can output power to the output shaft 200 through the second gear pair 600. Therefore, when the vehicle needs to be driven by the engine 100, the engine 100 can selectively transmit power to the output shaft 200 through the first gear pair 500 or the second gear pair 600, thereby adjusting the output torque of the engine 100.

[0077] In some specific embodiments of the present invention, Figure 1 , Figure 10-12 As shown, there are a plurality of clutches, and the plurality of clutches include a first clutch 710 and a second clutch 720 .

[0078] The first clutch 710 is disposed on the intermediate shaft 400 and connects or disconnects the intermediate shaft 400 with the first driving gear 510. In this way, the first driving gear 510 can be selectively connected or disconnected with the intermediate shaft 400, and the first driven gear 520 can remain connected with the output shaft 200, so that the driving motor 300 transmits power to the output shaft 200 through the output gear 320 and the first driven gear 520, and when the engine 100 stops working or the engine 100 is not needed to drive the vehicle, the first driving gear 510 can be disconnected from the intermediate shaft 400, thereby avoiding the engine 100 from interfering with the driving motor 300 outputting power to the output shaft 200, and the structural setting is more reasonable.

[0079] In addition, the second clutch 720 connects or disconnects the intermediate shaft 400 and / or the output shaft 200 with the second gear pair 600. In this way, when the engine 100 needs to output power to the output shaft 200 through the second gear pair 600, the second clutch 720 can connect the intermediate shaft 400 and / or the output shaft 200 with the second gear pair 600; and when the engine 100 does not need to output power to the output shaft 200, or the engine 100 chooses to output power to the output shaft 200 through the first gear pair 500, the second clutch 720 can disconnect the intermediate shaft 400 and / or the output shaft 200 from the second gear pair 600.

[0080] In some specific embodiments of the present invention, Figure 1 and Fig.10 As shown, the second clutch 720 is disposed on the output shaft 200 and connects or disconnects the output shaft 200 with the second driven gear 620. That is, the first clutch 710 can be disposed on the intermediate shaft 400 and the second clutch 720 can be disposed on the output shaft 200, so that the first clutch 710 and the second clutch 720 do not need to be staggered along the axial direction of the output shaft 200, which is conducive to reducing the axial size of the hybrid power system 1, so that the axial structure of the hybrid power system 1 is more compact.

[0081] In other specific embodiments of the present invention, Fig.11 and Fig.12 As shown, the second clutch 720 is disposed on the intermediate shaft 400 and connects or disconnects the intermediate shaft 400 with the second driving gear 610. In other words, both the first clutch 710 and the second clutch 720 can be disposed on the intermediate shaft 400, which is conducive to simplifying the layout of the clutches, facilitating assembly, and further simplifying the structure of the hybrid system 1.

[0082] Moreover, in this embodiment, the second driven gear 620 is always connected to the output shaft 200 , and the output gear 320 can also mesh with the second driven gear 620 , that is, the drive motor 300 can output power to the output shaft 200 through the output gear 320 and the second driven gear 620 .

[0083] In some specific embodiments of the present invention, Figure 1 As shown, the hybrid system 1 further includes an engine driving gear 120 and an engine driven gear 130 .

[0084] The engine driving gear 120 is drivingly connected to the engine shaft 110 , the engine driven gear 130 is connected to the intermediate shaft 400 , and the engine driven gear 130 is meshed with the engine driving gear 120 .

[0085] With such arrangement, the engine 100 can transmit power to the intermediate shaft 400 through the engine driving gear 120 and the engine driven gear 130, that is, the engine 100 can be decelerated and outputted through the engine driving gear 120 and the engine driven gear 130, thereby increasing the output torque of the engine 100, so that the driving force of the engine 100 is stronger and the drive is more reliable.

[0086] In some specific embodiments of the present invention, Fig.10 and Fig.12 As shown, the hybrid system 1 further includes.

[0087] The generator 800 is provided with an input gear 810, and the input gear 810 is meshed with the engine driving gear 120. The input gear 810 and the engine driven gear 130 can be respectively arranged on two opposite sides of the engine driving gear 120 in the radial direction.

[0088] In this way, the engine 100 can transmit power to the generator 800 through the engine driving gear 120 and the input gear 810 to drive the generator 800 to generate electricity. In addition, the input gear 810 directly meshes with the engine driving gear 120, and the connection structure is simple, which is convenient for layout and assembly.

[0089] In other specific embodiments of the present invention, Figure 1 and Fig.11 As shown, the hybrid system 1 further includes a generator 800 and an idler gear 820 .

[0090] The generator 800 is provided with an input gear 810 , and the idler gear 820 is provided between the engine driving gear 120 and the input gear 810 , and the idler gear 820 is meshed with the engine driving gear 120 and the input gear 810 respectively.

[0091] In this way, the engine 100 can transmit power to the generator 800 through the engine driving gear 120, the idler gear 820 and the input gear 810 to drive the generator 800 to generate electricity. In addition, the idler gear 820 can change the direction of the input gear 810, increase the transmission distance between the engine driving gear 120 and the input gear 810, and adjust the pressure angle to make the power transmission between the engine 100 and the generator 800 more stable and reliable.

[0092] In some specific embodiments of the present invention, Figure 1 As shown, along the radial direction of the intermediate shaft 400, the generator 800 is arranged opposite to the gear pair.

[0093] That is to say, the gear pair and the clutch can be arranged on the radial side of the generator 800, so that the gear pair and the clutch can utilize the side space of the generator 800, thereby improving the space utilization of the hybrid power system 1 and further reducing the axial size of the hybrid power system 1.

[0094] In some specific embodiments of the present invention, Figure 1 As shown, the hybrid system 1 further includes a differential 900 .

[0095] The differential 900 has a first bevel gear 910, and a second bevel gear 210 is provided at the end of the output shaft 200, and the first bevel gear 910 meshes with the second bevel gear 210. In this way, the transmission direction of the power can be changed by the cooperation of the first bevel gear 910 and the second bevel gear 210, that is, the power transmitted along the axial direction of the output shaft 200 can be changed to the radial direction of the output shaft 200.
