[0031] Reference below Figure 1-Figure 4A power system 100 implementing power according to a first aspect of the present invention is described.

[0032] like Figure 1-Figure 4 As shown, the power system 100 according to the first aspect of the present utility model includes an engine 6, a dual clutch 1, a first speed change mechanism 2, a second speed change mechanism 3, a drive motor 4 and a differential 7.

[0033] Specifically, the first end 11 of the dual clutch 1 is connected to the engine 6, the second end 12 of the dual clutch 1 is connected to the first bevel gear 8, and the third end 13 of the dual clutch 1 is connected to the second bevel gear 9. The first speed change mechanism 2 includes a third bevel gear 21, and the third bevel gear 21 is meshed with the first bevel gear 8. The second speed change mechanism 3 includes a fourth bevel gear 31, and the fourth bevel gear 31 is meshed with the second bevel gear 9. The drive motor 4 is connected to at least one of the first speed change mechanism 2 and the second speed change mechanism 3 through a coupling device 5. The differential 7 is connected to the second speed change mechanism 3.

[0034] For example, in Figure 1-Figure 4 In the example, the first end 11 of the dual clutch 1 is located on the side of the dual clutch 1 away from the second end 12. The second end 12 and the third end 13 of the dual clutch 1 are located on the same side of the dual clutch 1, wherein the third end 13 is sleeved on the outer periphery of the second end 12. The axial direction of the first bevel gear 8 and the axial direction of the third bevel gear 21 are perpendicular to each other. The axial direction of the second bevel gear 9 and the axial direction of the fourth bevel gear 31 are perpendicular to each other, and the third bevel gear 21 and the fourth bevel gear 31 are respectively located on both sides of the axial direction of the second bevel gear 9. Such an arrangement also facilitates the meshing of the third bevel gear 21 with the first bevel gear 8 and the meshing of the fourth bevel gear 31 with the second bevel gear 9.

[0035] One end of the first speed change mechanism 2 is connected to the coupling device 5, and the other end of the first speed change mechanism 2 is connected to the first bevel gear 8. And / or one end of the second speed change mechanism 3 is connected to the coupling device 5, and the other end of the second speed change mechanism 3 is connected to the second bevel gear 9.

[0036] like Figure 1-Figure 4 As shown, when the vehicle is in the direct drive mode of the engine 6, that is, when the engine 6 drives the power system 100, and the first bevel gear 8 is combined with the second end 12 of the dual clutch 1, and the second bevel gear 9 is disconnected from the third end 13 of the dual clutch 1, the power of the engine 6 can be transmitted to the first speed change mechanism 2 through the second end 12 of the dual clutch 1, thereby realizing the shifting of the first speed change mechanism 2. At this time, the transmission direction of the power will change from longitudinal to transverse with the transmission between the dual clutch 1 and the third bevel gear 21.

[0037] When the first bevel gear 8 is disconnected from the second end 12 of the dual clutch 1, and the second bevel gear 9 is connected to the third end 13 of the dual clutch 1, the power of the engine 6 can be transmitted to the second speed change mechanism 3 through the third end 13 of the dual clutch 1, thereby realizing the shifting of the second speed change mechanism 3. In this way, the power driving mode of direct drive of the engine 6 can be realized. At this time, the transmission direction of the power will change from longitudinal to transverse as the power is transmitted from the dual clutch 1 to the fourth bevel gear 31.

[0038] like Figure 1-Figure 4 As shown, when the vehicle is in the driving mode of the drive motor 4, the drive motor 4 can be connected to the first speed change mechanism 2 and the second speed change mechanism 3 respectively through the coupling device 5, so that the drive motor 4 drives the first speed change mechanism 2 and the second speed change mechanism 3, so that the vehicle can achieve gear shifting through the drive motor 4.

[0039] like Figure 1-Figure 4 As shown, when the vehicle is in the direct drive and power generation mode, the engine 6 drives the first speed change mechanism 2 and the second speed change mechanism 3 through the dual clutch 1. At this time, the drive motor 4 is connected to the coupling device 5 so that the power of the engine 6 can be transmitted to the drive motor 4, and then the drive motor 4 generates electricity. In this way, when the vehicle is driven by the engine 6, the drive motor 4 generates electricity synchronously.

[0040] When the vehicle is in hybrid driving mode, on the basis of direct drive and power generation mode, the state of the drive motor 4 is switched from power generation to drive. This arrangement can reduce the fuel consumption of the engine 6, reduce the emission of the vehicle, and also keep the drive motor 4 in a good working state, thereby improving the power excellence of the whole vehicle.

[0041] When the vehicle is in the extended range mode, the first bevel gear 8 is meshed with the third bevel gear 21, and the power driven by the engine 6 is transmitted to the first speed change mechanism 2 through the dual clutch 1, and the first speed change mechanism 2 transmits the power to the coupling device 5, and the coupling device 5 transmits the power to the drive motor 4, thereby, the engine 6 can drive the drive motor 4, so that the drive motor 4 can generate electricity, and the first gear of the extended range mode is realized. Or, the second bevel gear 9 is meshed with the fourth bevel gear 31, and the power of the engine 6 is transmitted to the second speed change mechanism 3 through the dual clutch 1, and the second speed change mechanism 3 transmits the power to the first speed change mechanism 2, and then the first speed change mechanism 2 transmits the power to the coupling device 5, and the coupling device 5 transmits the power to the drive motor 4, thereby, the engine 6 can drive the drive motor 4, so that the drive motor 4 can generate electricity, and the second gear of the extended range mode is realized. Such a configuration enables the drive motor 4 to charge the battery, thereby improving the vehicle's endurance and energy utilization.

[0042] Thus, the first transmission mechanism 2 and the second transmission mechanism 3 can be driven by the engine 6 to change speed, and the first transmission mechanism 2 and the second transmission mechanism 3 can also be driven by the drive motor 4 to change speed, so as to realize multi-gear operation in pure electric, hybrid, range-extending and engine 6 direct drive modes. And it can realize that the drive motor 4 is completely disconnected from the engine 6 in the engine 6 direct drive mode, different gears are used to generate electricity in the range-extending mode, power is output and power is generated respectively in different gears in the direct drive and power generation mode, and the engine 6 and the drive motor 4 output power in different gears in the hybrid drive mode, so that the hybrid system can have better power performance and economic performance.

[0043] In summary, by arranging the first bevel gear 8, the second bevel gear 9, the third bevel gear 21 and the fourth bevel gear 31, the output direction of the dual clutch 1 is changed from longitudinal to transverse, and the first speed change mechanism 2 and the second speed change mechanism 3 are respectively arranged on both sides of the dual clutch 1, so that the first speed change mechanism 2 and the second speed change mechanism 3 are both arranged transversely, and the engine 6 is arranged longitudinally, thereby shortening the longitudinal size of the power system 100 and also shortening the transverse size of the power system 100, which is beneficial to the arrangement of other structures on the chassis.

[0044] Therefore, various modes of the hybrid power system 100 can be realized, and the hybrid power system 100 can be arranged on a hybrid vehicle model with longitudinal placement requirements, thereby reducing the space occupied by the power system 100 and improving the applicability of the power system 100.

[0045] According to the power system 100 of the embodiment of the utility model, the first bevel gear 8, the second bevel gear 9, the third bevel gear 21 and the fourth bevel gear 31 are arranged so that the first speed change mechanism 2 and the second speed change mechanism 3 are both arranged horizontally. Therefore, compared with the traditional power system, the horizontal and vertical dimensions occupied by the power system 100 on the chassis are shortened, which is conducive to arranging other structures on the chassis, and can achieve the complete disconnection of the motor and the engine 6 in the direct drive mode of the engine 6, realize various modes of the hybrid power system 100, and improve the applicability of the vehicle.

[0046] According to some embodiments of the utility model, the coupling device 5 includes an idler shaft 51, a first transmission wheel 52, a second transmission wheel 53 and a first synchronizer 59. Specifically, the first transmission wheel 52 is arranged on the idler shaft 51, and the first transmission wheel 52 is connected to the first speed change mechanism 2 or the second speed change mechanism 3. The second transmission wheel 53 is arranged on the motor output shaft 41 of the driving motor 4, and the second transmission wheel 53 is meshed with the first transmission wheel 52. The first synchronizer 59 is arranged on the motor output shaft 41.

[0047] Reference Figure 1-Figure 2The first transmission wheel 52 is connected to the idler shaft 51 , and one end of the first transmission wheel 52 away from the drive motor 4 is connected to the first speed change mechanism 2 or the second speed change mechanism 3 .

[0048] Specifically, for example, in Figure 1 In the example of , the end of the first transmission wheel 52 away from the drive motor 4 is connected to the first speed change mechanism 2. Figure 2 In the example, the end of the first transmission wheel 52 away from the drive motor 4 can also be connected to the second speed change mechanism 3.

[0049] One end of the motor output shaft 41 is connected to the drive motor 4, and the other end of the motor output shaft 41 is sleeved with a second transmission wheel 53, and the second transmission wheel 53 is meshed with the first transmission wheel 52. In this way, when the drive motor 4 plays a driving role, the power of the drive motor 4 can be transmitted to the second transmission wheel 53 through the motor output shaft 41, and the second transmission wheel 53 transmits the power to the first transmission wheel 52, and the first transmission wheel 52 transmits the power to the first transmission mechanism 2 or the second transmission mechanism 3, thereby, the drive motor 4 can drive the first transmission mechanism 2 or the second transmission mechanism 3 to shift gears, and the vehicle adopts the drive motor 4 driving mode, which improves the energy conversion efficiency of the vehicle, so that the vehicle has better acceleration performance and power output, is suitable for fast starting and climbing and other working conditions, and has zero pollution and zero emission, which can effectively reduce carbon emissions and reduce air pollution.

[0050] like Figure 1 and Figure 2 As shown, the first synchronizer 59 can be used to connect the motor output shaft 41 and the second transmission wheel 53, that is, when the first synchronizer 59 is opened, the second transmission wheel 53 is only sleeved on the motor output shaft 41. At this time, when the motor output shaft 41 rotates, the power of the motor output shaft 41 cannot be transmitted to the second transmission wheel 53. When the first synchronizer 59 is combined with the second transmission wheel 53, the second transmission wheel 53 is connected to the motor output shaft 41. When the motor output shaft 41 rotates, the power of the motor output shaft 41 can be transmitted to the second transmission wheel 53, and the second transmission wheel 53 can continue to transmit the power to the first transmission wheel 52.

[0051] In this way, power transmission or interruption of the driving motor 4 can be realized, which is beneficial to switching the driving mode of the vehicle, and the motor and the engine 6 are completely disconnected in the direct drive mode of the engine 6, different gears are used to generate electricity in the extended-range mode, power is output and power is generated through different gears in the direct drive and power generation mode, and the engine 6 and the motor output power through different gears in the hybrid drive mode, etc., so that the vehicle can realize multiple power drive modes, so that this hybrid system can have better power performance and economic performance.

[0052] According to other embodiments of the utility model, the coupling device 5 includes a first intermediate shaft 54, a fifth transmission wheel 55 and a sixth transmission wheel 56. Specifically, the first intermediate shaft 54 ​​is provided with a third transmission wheel 541 and a fourth transmission wheel 542, the third transmission wheel 541 is connected to the first speed change mechanism 2, and the fourth transmission wheel 542 is connected to the second speed change mechanism 3. The fifth transmission wheel 55 is provided on the first intermediate shaft 54. The sixth transmission wheel 56 is provided on the motor output shaft 41, and the sixth transmission wheel 56 is meshed with the fifth transmission wheel 55.

[0053] For example, in Figure 3-Figure 4 In the example, the fifth transmission wheel 55 and the fourth transmission wheel 542 are respectively arranged at two ends of the length direction of the first intermediate shaft 54, and the sixth transmission wheel 56 is arranged on a side of the fifth transmission wheel 55 adjacent to the fourth transmission wheel 542. One end of the motor output shaft 41 is connected to the motor, and the other end of the motor output shaft 41 is provided with the sixth transmission wheel 56.

[0054] With such a configuration, when the vehicle is in the driving mode of the driving motor 4, the driving motor 4 transmits power to the motor output shaft 41, the motor output shaft 41 drives the sixth transmission wheel 56 to rotate, the sixth transmission wheel 56 transmits power to the fifth transmission wheel 55, and drives the fifth transmission wheel 55 to rotate, and then the fifth transmission wheel 55 drives the first intermediate shaft 54 ​​to rotate. Thus, the first intermediate shaft 54 ​​can drive the third transmission wheel 541 or the fourth transmission wheel 542 to rotate, so that power can be transmitted to the first speed change mechanism 2 or the second speed change mechanism 3. Thus, the driving motor 4 can drive the first speed change mechanism 2 or the second speed change mechanism 3, so that the first speed change mechanism 2 or the second speed change mechanism 3 can achieve gear shifting.

[0055] When the drive motor 4 generates electricity, it needs to receive power transmitted from the engine 6 and the first speed change mechanism 2 or the engine 6 and the second speed change mechanism 3 to enable the drive motor 4 to generate electricity.

[0056] In this way, the driving motor 4 and the first transmission mechanism 2 or the second transmission mechanism 3 can be turned on and off, which facilitates the switching of the driving mode of the driving motor 4, the direct drive mode of the engine 6, or the direct drive and power generation mode of the engine 6, thereby improving the applicability of the power system 100.

[0057] Furthermore, the coupling device 5 further includes a second synchronizer 57 and a third synchronizer 58. The second synchronizer 57 is disposed on the first intermediate shaft 54. The third synchronizer 58 is disposed on the first intermediate shaft 54, and the second synchronizer 57 and the third synchronizer 58 are located between the third transmission wheel 541 and the fourth transmission wheel 542. Figure 3-Figure 4The second synchronizer 57 is arranged on a side adjacent to the third transmission wheel 541, and the third synchronizer 58 is arranged on a side adjacent to the fourth transmission wheel 542. The second synchronizer 57 can connect the third transmission wheel 541 with the first intermediate shaft 54, so that the power on the first intermediate shaft 54 ​​is transmitted to the third transmission wheel 541. The third synchronizer 58 can connect the fourth transmission wheel 542 with the first intermediate shaft 54, so that the power on the first intermediate shaft 54 ​​is transmitted to the fourth transmission wheel 542.

[0058] Specifically, when the second synchronizer 57 is combined with the third transmission wheel 541, the power of the drive motor 4 can be transmitted to the third transmission wheel 541 through the coupling device 5, and the third transmission wheel 541 can rotate and transmit the power to the first speed change mechanism 2, so that the drive motor 4 can drive the first speed change mechanism 2, so that the first speed change mechanism 2 can achieve gear shifting. Or, the power of the engine 6 can be transmitted to the coupling device 5 and the drive motor 4 through the first speed change mechanism 2, so that the drive motor 4 can generate electricity in the engine 6 direct drive mode.

[0059] When the third synchronizer 58 is combined with the fourth transmission wheel 542, the power of the drive motor 4 can be transmitted to the fourth transmission wheel 542 through the coupling device 5, and the fourth transmission wheel 542 can rotate and transmit the power to the second speed change mechanism 3, so that the drive motor 4 can drive the second speed change mechanism 3, so that the second speed change mechanism 3 can achieve gear shifting. Alternatively, the power of the engine 6 can be transmitted to the coupling device 5 and the drive motor 4 through the second speed change mechanism 3, so that the drive motor 4 can generate electricity in the engine 6 direct drive mode.

[0060] With such arrangement, the drive motor 4 can respectively drive the first transmission mechanism 2 and the second transmission mechanism 3 to shift gears, and the second synchronizer 57 and the third synchronizer 58 can realize power transmission or interruption of the drive motor 4, which is beneficial for the vehicle to switch drive modes, enable the vehicle to realize multiple power drive modes, and help the vehicle to have better power performance and economic performance.

[0061] According to some embodiments of the utility model, the power system 100 further includes a second intermediate shaft 10, a third intermediate shaft 20 and a first output shaft 40. The second intermediate shaft 10 is provided with a third bevel gear 21. The third intermediate shaft 20 is provided with a fourth bevel gear 31. The first output shaft 40 is connected to the differential 7 through a transmission mechanism 70.

[0062] like Figure 1-Figure 4As shown, the second intermediate shaft 10 and the third intermediate shaft 20 are both arranged on the side adjacent to the dual clutch 1, and the second intermediate shaft 10 and the third intermediate shaft 20 are respectively located on both sides of the dual clutch 1. The second intermediate shaft 10 and the third intermediate shaft 20 both extend in the lateral direction of the vehicle. The third bevel gear 21 is located at one end of the length direction of the second intermediate shaft 10, and the fourth bevel gear 31 is located at one end of the length direction of the third intermediate shaft 20. When the engine 6 is driven, the third bevel gear 21 receives power and starts to rotate, which can drive the second intermediate shaft 10 to rotate, and the fourth bevel gear 31 receives power and starts to rotate, which can drive the third intermediate shaft 20 to rotate.

[0063] The first output shaft 40 is arranged between the second intermediate shaft 10 and the drive motor 4. The first output shaft 40 is connected to the first speed change mechanism 2 and the second speed change mechanism 3, and one end of the first output shaft 40 in the length direction is connected to the transmission mechanism 70. Therefore, the power of the first output shaft 40 can be transmitted to the differential 7 through the transmission mechanism 70. In this way, the power of the first speed change mechanism 2 and the second speed change mechanism 3 can be transmitted to the wheels, so that the wheels can rotate and achieve different speeds. In addition, when the vehicle is running on an uneven road surface or a turn, the differential 7 can realize the differential movement of the wheels, so that the vehicle can run smoothly, which is beneficial to the riding experience of the passengers.

[0064] According to some embodiments of the utility model, the first speed change mechanism 2 further includes a first gear pair 22, a second gear pair 23 and a third gear pair 24. A fourth synchronizer 25 is provided between the second gear pair 23 and the first gear pair 22. A fifth synchronizer 26 is provided between the third gear pair 24 and the second gear pair 23; wherein the fifth synchronizer 26 is provided on the second intermediate shaft 10 or the first output shaft 40.

[0065] For example, in Figure 1-Figure 4 In the example, the first gear pair 22, the second gear pair 23 and the third gear pair 24 are arranged at intervals along the length direction of the second intermediate shaft 10, the first gear pair 22 is located on the side close to the third bevel gear, and the second gear pair 23 is located between the first gear pair 22 and the third gear pair 24. Among them, the first gear pair 22 is a first gear, the second gear pair 23 is a fifth gear, and the third gear pair 24 is a third gear. When the power system 100 is shifted, the power needs to pass through the gear of the corresponding gear during transmission, so that the speed of the power output is the gear of the corresponding gear, so that the speed of the wheel changes accordingly.

[0066] The fourth synchronizer 25 can be combined with the first gear pair 22 or the second gear pair 23, so that the first output shaft 40 is connected to the first gear pair 22 or the second gear pair 23, so that the output speed of the first output shaft 40 is transmitted by the corresponding gear pair. The fifth synchronizer 26 can be combined with the third gear pair 24, so that the output speed of the first output shaft 40 is transmitted by the corresponding gear pair. Figure 1-Figure 3 As shown, the fifth synchronizer 26 is arranged on the second intermediate shaft 10. Figure 4 As shown, the fifth synchronizer 26 is disposed on the first output shaft 40 .

[0067] Among them, only one of the fourth synchronizer 25 and the fifth synchronizer 26 is in a combined state with the other gear pair at the same time, so that the speed output from the first speed change mechanism 2 to the first output shaft 40 is unique.

[0068] In summary, the first transmission mechanism 2 is arranged horizontally with odd-numbered gears, which not only reduces the longitudinal size of the first transmission mechanism 2, but also facilitates the engagement and opening of the fourth synchronizer 25 and the fifth synchronizer 26, facilitates gear shifting, reduces friction and vibration during gear shifting, and improves the riding experience of passengers.

[0069] Furthermore, the first gear pair 22 includes a first driving gear 221 and a first driven gear 222 meshing with each other, the second gear pair 23 includes a second driving gear 231 and a second driven gear 232 meshing with each other, and the third gear pair 24 includes a third driving gear 241 and a third driven gear 242 meshing with each other.

The third driving gear 241 and the third driven gear 242 are arranged along the radial direction of the third driving gear 241. The first driving gear 221, the second driving gear 231 and the third driving gear 241 are arranged at intervals on the second intermediate shaft 10, and the first driven gear 222, the second driven gear 232 and the third driven gear 242 are arranged at intervals on the first output shaft 40. Among them, the fourth synchronizer 25 is located between the first driven gear 222 and the second driven gear 232.

[0072] Generally, the first driven gear 222 and the second driven gear 232 are both sleeved on the first output shaft 40 , that is, no power can be transmitted between the first driven gear 222 and the second driven gear 232 and the first output shaft 40 .

[0073] When the fourth synchronizer 25 is combined with the first driven gear 222, the first driven gear 222 is connected to the first output shaft 40, so that the first driven gear 222 can drive the first output shaft 40 to rotate, so that the power of the first driven gear 222 can be transmitted to the differential 7 and the wheels through the first output shaft 40. When the fourth synchronizer 25 is combined with the second driven gear 232, the second driven gear 232 is connected to the first output shaft 40, so that the second driven gear 232 can drive the first output shaft 40 to rotate, so that the power of the second driven gear 232 can be transmitted to the differential 7 and the wheels through the first output shaft 40. Therefore, the first output shaft 40 can output the speed of the first gear pair 22 or the second gear pair 23, and transmit the power to the wheels through the differential 7, so that the speed of the wheels changes, thereby realizing the gear conversion.

[0074] Specifically, when the power driving mode is the driving mode of the driving motor 4, refer to Figure 1 , the driving motor 4 transmits power to the first driven gear 222 through the coupling device 5. At this time, when the fourth synchronizer 25 connects the first driven gear 222 with the first output shaft 40, the first driven gear 222 can drive the first output shaft 40 to rotate, and the first output shaft 40 can transmit power to the differential 7 and the wheels, and the wheel speed changes to the first gear.

[0075] When the fourth synchronizer 25 connects the second driven gear 232 to the first output shaft 40 , the second driven gear 232 can drive the first output shaft 40 to rotate, and the first output shaft 40 can transmit power to the differential 7 and the wheels, and the wheel speed changes to the fifth gear.

[0076] When the power drive mode is the engine 6 direct drive mode, refer to Figure 1 , the first bevel gear 8 is meshed with the third bevel gear 21, so that the power of the engine 6 can be transmitted to the second intermediate shaft 10, and the second intermediate shaft 10 transmits the power to the first driving gear 221. At this time, when the fourth synchronizer 25 connects the first driven gear 222 with the first output shaft 40, after the first driving gear 221 transmits the power to the first driven gear 222, the first driven gear 222 can drive the first output shaft 40 to rotate, and the first output shaft 40 can transmit the power to the differential 7 and the wheels, and the wheel speed changes to the first gear. At this time, the second synchronizer 57 is combined with the second transmission wheel 53, and the second transmission wheel 53 is connected to the first intermediate shaft 54, so that the power of the first driven gear 222 can be transmitted to the second transmission wheel 53 through the first transmission wheel 52, and the second transmission wheel 53 transmits the power to the first intermediate shaft 54, and the first intermediate shaft 54 ​​transmits the power to the drive motor 4, thereby, the drive motor 4 can receive the power of the engine 6, and the drive motor 4 can generate electricity. At this time, the engine 6 direct drive and power generation mode of the first gear can be realized.

[0077] When the fourth synchronizer 25 connects the second driven gear 232 with the first output shaft 40, the second driving gear 231 transmits power to the second driven gear 232, and the second driven gear 232 can drive the first output shaft 40 to rotate. The first output shaft 40 can transmit power to the differential 7 and the wheels, and the wheel speed changes to fifth gear. At this time, the second synchronizer 57 is combined with the second transmission wheel 53, and the second transmission wheel 53 is connected to the first intermediate shaft 54, and the fourth synchronizer 25 connects the first driven gear 222 to the first output shaft 40, thereby, the power of the second driven gear 232 can be transmitted to the first driven gear 222 through the first output shaft 40, the power of the first driven gear 222 is transmitted to the second transmission wheel 53 through the first transmission wheel 52, the second transmission wheel 53 then transmits the power to the first intermediate shaft 54, the first intermediate shaft 54 ​​transmits the power to the drive motor 4, thereby, the drive motor 4 can receive the power of the engine 6, the drive motor 4 can generate electricity, and at this time, the 5th gear engine 6 direct drive and power generation mode can be realized.

[0078] Power transmission can be achieved between the third driving gear 241 and the third driven gear 242. When the second intermediate shaft 10 transmits power to the third driving gear 241, the third driving gear 241 can drive the third driven gear 242 to rotate, so that the third driven gear 242 can transmit power to the first output shaft 40, and the first output shaft 40 can transmit power to the differential 7 and the wheels, and the wheel speed changes to the third gear. At this time, the second synchronizer 57 is combined with the second transmission wheel 53, and the second transmission wheel 53 is connected to the first intermediate shaft 54, and the fourth synchronizer 25 connects the first driven gear 222 to the first output shaft 40, thereby, the power of the third driven gear 242 can be transmitted to the first driven gear 222 through the first output shaft 40, the power of the first driven gear 222 is transmitted to the second transmission wheel 53 through the first transmission wheel 52, the second transmission wheel 53 then transmits the power to the first intermediate shaft 54, the first intermediate shaft 54 ​​transmits the power to the drive motor 4, thereby, the drive motor 4 can receive the power of the engine 6, the drive motor 4 can generate electricity, and at this time, the 3rd gear engine 6 direct drive and power generation mode can be realized.

[0079] With such an arrangement, the gear shifting of the first gear pair 22 , the second gear pair 23 and the third gear pair 24 can be realized, and can be realized in multiple modes, which is beneficial to improving the applicability of the power system 100 .

[0080] In addition, when the third driving gear 241 is sleeved on the first intermediate shaft 54, as shown in FIG. Figure 1As shown, the fifth synchronizer 26 is disposed on the second intermediate shaft 10. When the fifth synchronizer 26 is combined with the third driving gear 241, the third driving gear 241 is connected to the second intermediate shaft 10, and the third driving gear 241 can drive the second intermediate shaft 10 to rotate, so that the power of the third driving gear 241 can be transmitted to the second intermediate shaft 10.

[0081] When the third driven gear 242 is sleeved on the first output shaft 40, as shown in FIG. Figure 1 As shown, the fifth synchronizer 26 is disposed on the first output shaft 40. When the fifth synchronizer 26 is combined with the third driven gear 242, the third driven gear 242 is connected to the first output shaft 40, and the third driven gear 242 can drive the first output shaft 40 to rotate, so that the power of the third driven gear 242 can be transmitted to the first output shaft 40.

[0082] When the fifth synchronizer 26 is disposed on the second intermediate shaft 10, the fifth synchronizer 26 is combined with the third driving gear 241 to connect the third driving gear 241 to the second intermediate shaft 10. When the fifth synchronizer 26 is disposed on the first output shaft 40, the fifth synchronizer 26 is combined with the third driven gear 242 to connect the third driven gear 242 to the first output shaft 40, and the third driven gear 242 can drive the first output shaft 40 to rotate.

[0083] When the power drive mode is the drive motor 4 drive mode, refer to Figure 1 The power of the driving motor 4 can be transmitted to the first gear pair 22 through the first intermediate shaft 54 ​​and the coupling device 5. Since the first driving gear 221 is connected to the second intermediate shaft 10, the first driven gear 222 can drive the second intermediate shaft 10 to rotate, so that the second intermediate shaft 10 can transmit the power to the third driving gear 241, and the third driving gear 241 then transmits the power to the third driven gear 242. The third driven gear 242 drives the first output shaft 40 to rotate, and finally the first output shaft 40 is transmitted to the wheels through the differential 7, thereby completing the gear switching of the third gear.

[0084] When the power drive mode is the engine 6 direct drive mode, refer to Figure 1 The first bevel gear 8 meshes with the third bevel gear 21, so that the power of the engine 6 can be transmitted to the second intermediate shaft 10, and the second intermediate shaft 10 transmits the power to the third driving gear 241, the third driving gear 241 drives the third driven gear 242 to rotate, and then the third driven gear 242 drives the first output shaft 40 to rotate, and finally the first output shaft 40 transmits the power from the differential 7 to the wheels, so that the speed of the wheels changes, and the gear switching of the third gear is realized.

[0085] With such an arrangement, the gear shift of the third gear pair 24 can be realized, and can be realized in multiple modes, which is beneficial to improving the applicability of the power system 100.

[0086] According to some embodiments of the utility model, the second speed change mechanism 3 further includes a fourth gear pair 32, a fifth gear pair 33, a sixth gear pair 34 and an eighth synchronizer 50. A sixth synchronizer 35 is provided between the fifth gear pair 33 and the fourth gear pair 32. A seventh synchronizer 36 is provided between the sixth gear pair 34 and the fifth gear pair 33; an eighth synchronizer 50, the eighth synchronizer 50 is provided on the first output shaft 40, and the eighth synchronizer 50 is located between the first gear pair 22 and the fourth gear pair 32; wherein the fourth gear pair 32 includes a fourth driving gear 321 and a fourth driven gear 322 meshing with each other, the fifth gear pair 33 includes a fifth driving gear 331 and a fifth driven gear 332 meshing with each other, and the sixth gear pair 34 includes a sixth driving gear 341 and a sixth driven gear 342 meshing with each other.

[0087] The fourth driving gear 321 , the fifth driving gear 331 , the sixth driving gear 341 and the seventh synchronizer 36 are disposed on the third intermediate shaft 20 , and the fourth driven gear 322 , the fifth driven gear 332 , the sixth driven gear 342 and the sixth synchronizer 35 are disposed on the first output shaft 40 .

[0088] For example, in Figure 1-Figure 4 In the example, the fourth gear pair 32, the fifth gear pair 33 and the sixth gear pair 34 are arranged at intervals along the length direction of the third intermediate shaft 20, the fourth gear pair 32 is located on the side close to the fourth bevel gear, and the fifth gear pair 33 is located between the fourth gear pair 32 and the sixth gear pair 34. Among them, the fourth gear pair 32 is a second gear, the fifth gear pair 33 is a sixth gear, and the sixth gear pair 34 is a fourth gear. When the power system 100 is shifted, the power needs to pass through the gear of the corresponding gear during transmission, so that the speed of the power output is the gear of the corresponding gear, so that the speed of the wheel changes accordingly.

[0089] The sixth synchronizer 35 can be combined with the fourth gear pair 32 or the fifth gear pair 33, so that the first output shaft 40 is connected with the fourth gear pair 32 or the fifth gear pair 33, so that the output speed of the first output shaft 40 is transmitted by the corresponding gear pair. The seventh synchronizer 36 can be combined with the sixth gear pair 34, so that the output speed of the first output shaft 40 is transmitted by the corresponding gear pair. Among them, only one of the sixth synchronizer 35 and the seventh synchronizer 36 will be in a combined state with the other gear pair at the same time, so that the speed output from the second speed change mechanism 3 to the first output shaft 40 is unique.

[0090] like Figure 1As shown, the eighth synchronizer 50 is arranged in the middle of the first output shaft 40, and one end of the eighth synchronizer 50 is connected to the fourth gear pair 32. The eighth synchronizer 50 is used to connect the first gear pair 22 and the fourth gear pair 32. Therefore, when the drive motor 4 is driven, the power of the drive motor 4 can be transmitted to the coupling device 5 by the motor output shaft 41, and the coupling device 5 then transmits the power to the first gear pair 22. After the first gear pair 22 is connected to the fourth gear pair 32 through the eighth synchronizer 50, the first gear pair 22 can transmit the power to the fourth gear pair 32, so that the drive motor 4 can drive the second speed change mechanism 3. Such a setting enables the power system 100 to realize the gear winding function, and can realize the speed change of up to 8 gears through six pairs of gear pairs, which greatly shortens the horizontal size of the power system 100.

[0091] Further, refer to Figure 1-Figure 4 The fourth driving gear 321 and the fourth driven gear 322 are arranged along the radial direction of the fourth driving gear 321 , and the fifth driving gear 331 and the fifth driven gear 332 are arranged along the radial direction of the fifth driving gear 331 . The sixth driving gear 341 and the sixth driven gear 342 are arranged along the radial direction of the sixth driving gear 341 .

[0092] The fourth driving gear 321, the fifth driving gear 331 and the sixth driving gear 341 are arranged at intervals on the third intermediate shaft 20, and the seventh driven gear, the fifth driven gear 332 and the sixth driven gear 342 are arranged at intervals on the first output shaft 40. The sixth synchronizer 35 is located between the fourth driven gear 322 and the fifth driven gear 332.

[0093] Generally, the fourth driven gear 322 and the fifth driven gear 332 are both sleeved on the first output shaft 40 , that is, power cannot be transmitted between the fourth driven gear 322 and the fifth driven gear 332 and the first output shaft 40 .

[0094] When the sixth synchronizer 35 is combined with the fourth driven gear 322, the fourth driven gear 322 is connected to the first output shaft 40, so that the fourth driven gear 322 can drive the first output shaft 40 to rotate, so that the power of the fourth driven gear 322 can be transmitted to the differential 7 and the wheels through the first output shaft 40. When the sixth synchronizer 35 is combined with the fifth driven gear 332, the fifth driven gear 332 is connected to the first output shaft 40, so that the fifth driven gear 332 can drive the first output shaft 40 to rotate, so that the power of the fifth driven gear 332 can be transmitted to the differential 7 and the wheels through the first output shaft 40. Therefore, the first output shaft 40 can output the speed of the fourth gear pair 32 or the fifth gear pair 33, and transmit the power to the wheels through the differential 7, so that the speed of the wheels changes, thereby realizing the conversion of the gear position.

[0095] In summary, arranging the second speed change mechanism 3 horizontally with even gears not only reduces the longitudinal and lateral dimensions of the second speed change mechanism 3, but also facilitates the engagement and opening of the sixth synchronizer 35 and the seventh synchronizer 36, thus facilitating gear shifting, reducing friction and vibration during gear shifting, and improving the riding experience of passengers.

The power transmitted from the first output shaft 40 can be transmitted to the seventh transmission wheel 701, and the seventh transmission wheel 701 transmits the power to the eighth transmission wheel 702 and the ninth transmission wheel 703, and the ninth transmission wheel 703 transmits the power to the differential 7, so that the differential 7 can finally transmit the power transmitted from the first output shaft 40 to the wheels, so that the wheels can start to rotate.

[0110] In this way, the power of the power system 100 is transmitted to the wheels, thereby enabling the vehicle to travel.

[0111] The vehicle (not shown) according to the embodiment of the second aspect of the utility model comprises the power system 100 of the embodiment of the first aspect of the utility model.

[0112] According to the vehicle of the embodiment of the utility model, by adopting the above-mentioned power system 100, the longitudinal and lateral dimensions of the power system 100 of the vehicle are reduced, which is convenient for the arrangement of other structures of the vehicle chassis, improves the space utilization of the vehicle chassis, improves the power transmission efficiency, and realizes multiple driving modes, thereby improving the power performance and economic performance of the vehicle and improving the market competitiveness of the vehicle.

[0113] In summary, the power system 100 according to the embodiment of the present utility model has the following driving modes:

[0114] 1. Driving mode of the driving motor 4. At this time, the driving motor 4 can be connected to the first speed change mechanism 2 and the second speed change mechanism 3 respectively through the coupling device 5, so that the driving motor 4 can drive the first speed change mechanism 2 and the second speed change mechanism 3, so that the vehicle can be driven by the driving motor 4 to achieve gear shifting.

[0115] 2. Direct drive mode of engine 6. The engine 6 is connected to the first transmission mechanism 2 or the second transmission mechanism 3 through the dual clutch 1, so that the power of the engine 6 can be transmitted to different gear pairs, thereby changing the rotation speed of the first output shaft 40 and the rotation speed transmitted from the first output shaft 40 to the wheels, thereby realizing the speed change of the wheels.

[0116] 3. Engine 6 direct drive and power generation mode. At this time, on the basis of the engine 6 driving, the drive motor 4 is connected to the coupling device 5, and the drive motor 4 is connected to the first speed change mechanism 2 and the second speed change mechanism 3 through the coupling device 5, so that the power of the engine 6 can be transmitted to the drive motor 4 through the first speed change mechanism 2 and the second speed change mechanism 3, and then the drive motor 4 generates electricity, so that when the vehicle is driven by the engine 6, the drive motor 4 generates electricity synchronously.

[0117] 4. Hybrid power driving mode: Based on the direct drive and power generation mode, the state of the driving motor 4 is switched from power generation to driving, driving the first speed change mechanism 2 or the second speed change mechanism 3, thereby reducing the energy consumption of the engine 6.

[0118] 5. Extended range mode. The power driven by the engine 6 is transmitted to the first transmission mechanism 2 or the second transmission mechanism 3 through the dual clutch 1. The first transmission mechanism or the second transmission mechanism 3 transmits the power to the coupling device 5, and the coupling device 5 transmits the power to the drive motor 4. Thus, the engine 6 can drive the drive motor 4 to enable the drive motor 4 to generate electricity.

[0119] In addition, there are other driving modes not listed one by one.
