[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 4 As shown, an embodiment of the utility model provides a hybrid transmission system, which includes a power mechanism 10 and a lubrication mechanism 20. The power mechanism 10 includes an engine 11, a generator 12, a drive motor 13, a first differential 14 and a transmission assembly 15. The engine 11 and the generator 12 are coaxially arranged, and the output shaft of the engine 11 is connected to the motor shaft of the generator 12. The drive motor 13 and the first differential 14 are coaxially arranged, and the drive shaft of the drive motor 13 and the first differential 14 are connected through the transmission assembly 15; the lubrication mechanism 20 includes an oil storage member 21 and an oil pipe 22, and the transmission assembly 15 includes a transmission shaft. The oil storage member 21 can provide lubricating oil to the engine 11, the generator 12, the bearings of the motor shaft, the bearings of the drive shaft, the bearings of the transmission shaft, and the bearings of the first differential 14 through the oil pipe 22.

[0027] By applying the technical solution of the utility model, the hybrid transmission system includes a power mechanism 10 and a lubrication mechanism 20. When the drive motor 13 drives the first differential 14 to work through the transmission assembly 15, the vehicle can be operated in a pure electric mode. When the engine 11 drives the generator 12 to generate electricity, the vehicle can be operated in an extended range mode. In addition, in the above working modes, the lubricating oil in the oil storage member 21 is discharged by the oil pipe 22, so as to lubricate the engine 11, the generator 12, the bearings of the motor shaft, the bearings of the drive shaft, the bearings of the transmission shaft, and the bearings of the first differential 14. Since the engine 11 and the generator 12 are coaxially arranged, and the drive motor 13 and the first differential 14 are coaxially arranged, the space occupied by the power mechanism 10 can be reduced, thereby achieving the purpose of sharing the front cabin of the pure electric vehicle and the hybrid vehicle.

[0028] The oil storage member 21 may be an oil pool or an oil tank.

[0029] In this embodiment, since the front cabin of the pure electric vehicle and the hybrid vehicle is shared, the sharing of peripheral parts such as suspensions can be maximized to achieve the best vehicle development cost.

[0030] like Figure 2As shown, the oil pipe 22 includes a first main pipe 221 and a first branch pipe 222, a second branch pipe 223, a third branch pipe 224, a fourth branch pipe 225, and a fifth branch pipe 226 connected to the first main pipe 221.

The first main pipe 221 is provided with an electronic oil pump 24, and the fifth branch pipe 226 provides lubricating oil for the drive motor 13. With the above structure, when the vehicle is working, the electronic oil pump 24 can pump the oil in the oil storage member 21 and guide it out through the oil pipe 22 to lubricate the front bearing and rear bearing of the transmission shaft, the front bearing and rear bearing of the drive shaft, and the drive motor 13.

[0031] like Figure 1 As shown, the transmission assembly 15 further includes a first gear 151, a second gear 152, a third gear 153, and a fourth gear 154. The first gear 151 and the fourth gear 154 are respectively arranged on both sides of the transmission shaft, the second gear 152 is arranged on the drive shaft, and the third gear 153 is arranged on the first differential 14.

The oil pipe 22 further includes a sixth branch pipe 227 connected to the first main pipe 221, and the outlet of the sixth branch pipe 227 is arranged at the meshing position of the first gear 151 and the second gear 152. With the above structure, when the vehicle is working, the meshing position of the second gear 152 and the third gear 153 can be lubricated by the sixth branch pipe 227.

[0032] Specifically, when the vehicle is in pure electric working mode, the drive motor 13 drives the second gear 152 to rotate through its drive shaft, the second gear 152 drives the first gear 151 to rotate, the first gear 151 drives the fourth gear 154 to rotate through the transmission shaft, and the fourth gear 154 drives the first differential 14 to work through the third gear 153, thereby driving the vehicle to move.

[0033] Furthermore, when the vehicle is in the extended-range operation mode, the engine 11 drives the generator 12 to generate electricity, which is stored in the power battery. The power battery then drives the motor to operate, thereby driving the vehicle to travel.

[0034] The hybrid transmission system further includes a rear wheel motor and a second differential connected to the rear wheel motor. The rear wheel motor drives the rear wheel to rotate through the second differential, thereby realizing rear wheel drive of the vehicle.

[0035] In this embodiment, when the vehicle is in the extended range working mode, the engine 11 drives the generator 12 to generate electricity, and the rear wheels can be driven by the motor to achieve rear wheel drive. At this time, the drive motor 13 can drive the first differential 14 to work, and realize the front wheel drive of the vehicle. Then, the engine 11 can be used to realize the four-wheel drive working mode of the vehicle, or as an auxiliary drive of a four-wheel drive vehicle.

[0036] like Figure 3 As shown, the oil pipe 22 also includes a second main pipe 23 and a seventh branch pipe 231, an eighth branch pipe 232, and a ninth branch pipe 233 connected to the second main pipe 23. The second main pipe 23 is connected to the oil storage member 21, the seventh branch pipe 231 is connected to the front bearing oil hole of the motor shaft, the eighth branch pipe 232 is connected to the rear bearing oil hole of the motor shaft, and the ninth branch pipe 233 provides lubricating oil for the generator 12. A coaxial oil pump 25 is provided on the second main pipe 23, and the pump shaft of the coaxial oil pump 25 is connected to the motor shaft. When the vehicle is idling and generating electricity, the generator 12 is working, and the coaxial oil pump 25 can pump the oil in the oil storage member 21 and guide it out through the oil pipe 22 to lubricate the front bearing and rear bearing of the motor shaft and the generator 12.

[0037] like Figure 4 As shown, the lubrication mechanism further includes a valve 26, which is arranged on the first main pipe 221 and is located downstream of the electronic oil pump 24. The second main pipe 23 includes a first section 235 and a second section 236. One end of the first section 235 is connected to the oil storage member 21, and the other end of the first section 235 is connected to the valve 26. The coaxial oil pump 25 is arranged on the first section 235, and one end of the second section 236 is connected to the valve 26. The seventh branch pipe 231, the eighth branch pipe 232 and the ninth branch pipe 233 are all connected to the second section 236. With the above structure, the working state of the first main pipe 221 and the second main pipe 23 can be adjusted by the valve 26, thereby realizing lubrication in different working modes of the vehicle.

[0038] Specifically, when the drive motor 13 is working, the first main pipe 221 is opened through the valve 26, and the electronic oil pump 24 can be used to pump the lubricating oil and deliver it to various lubrication points through the first main pipe 221. When the generator 12 is working, the first section 235 and the second section 236 of the second main pipe 23 can be connected through the valve, and the coaxial oil pump 25 can be used to pump the lubricating oil and deliver it to various lubrication points through the second main pipe 23.

[0039] like Figure 3 As shown, the second main pipe 23 also includes a supplementary pipe 234, the two ends of which are respectively connected to the first section 235 and the first main pipe 221, and the connecting point between the supplementary pipe 234 and the first main pipe 221 is located between the electronic oil pump 24 and the valve 26. When the amount of oil pumped by the coaxial oil pump 25 is insufficient, the oil can be supplemented by using the electronic oil pump 24 and through the supplementary pipe 234.

[0040] In this embodiment, the lubricating mechanism further includes an oil cooler 27, which is disposed on the first main pipe 221 and upstream of the valve 26. The oil cooler 27 can be used to cool the lubricating oil to a suitable lubricating temperature.

[0041] like Figure 2 As shown, part of the third gear 153 is located in the oil storage member 21. When the third gear 153 rotates, the oil storage member 21 can provide lubricating oil to the front bearing of the first differential 14, the rear bearing of the first differential 14, and the meshing portion of the third gear 153 and the fourth gear 154. With the above arrangement, when the third gear 153 rotates, the lubricating oil in the oil storage member 21 can be stirred, causing the lubricating oil to churn and lubricate the front and rear bearings of the first differential 14 and the meshing portion of the third gear 153 and the fourth gear 154.

[0042] like Figure 1 As shown, the drive shaft is connected to the output shaft of the first differential 14. With the above structure, the power transmission efficiency can be improved.

[0043] Another embodiment of the utility model provides a vehicle, the vehicle includes the hybrid transmission system provided above. When the drive motor 13 drives the first differential 14 to work through the transmission assembly 15, the vehicle can be operated in a pure electric mode, and when the engine 11 drives the generator 12 to generate electricity, the vehicle can be operated in an extended range mode. Since the engine 11 and the generator 12 are coaxially arranged, and the drive motor 13 and the first differential 14 are coaxially arranged, the space occupied by the power mechanism 10 can be reduced, thereby achieving the purpose of sharing the front cabin of the pure electric vehicle and the hybrid vehicle.
