Description

Technical Field

[0001] This disclosure relates to the field of vehicle transmission technology, and more particularly to a hybrid power system and vehicle. Background Technology

[0002] With the development of hybrid technology, range-extended hybrids are becoming increasingly popular with customers. Electrification is rapidly driving a revolution in automotive powertrains, but range anxiety remains a persistent concern for pure electric vehicles. Range-extended electric vehicles (REEVs) can effectively address this range anxiety issue, but their inability to be directly driven by an engine results in higher fuel consumption at high speeds. Furthermore, the performance of REEVs is limited by the power of the drive motor; increasing the motor's power would require further investment in performance, leading to higher costs.

[0003] The mainstream P1+P3 or P2+P3 configuration range-extended electric vehicle solutions in the automotive industry can effectively solve the problem of high fuel consumption in range-extended vehicles, but they have complex structures, high costs, and large engine compartment space requirements.

[0023] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0025] Figure 1 This is a schematic diagram of a hybrid power system provided in an embodiment of this disclosure, with reference to... Figure 1 This embodiment provides a hybrid power system, including:

[0026] The transmission system assembly 10 has a power input end and a power output end that are connected by transmission. The power output end is selectively connected to the wheel 20 through a first clutch C1.

[0027] Motor 30 is connected to the power input end via a connecting shaft;

[0028] Engine 40, which is selectively connected to motor 30 via second clutch C2;

[0029] The hybrid system also includes an air conditioning compressor 50, which is selectively connected to the motor 30 via a third clutch C3.

[0030] Specifically, the hybrid power system provided in this embodiment includes a transmission system component 10, a motor 30, and an engine 40. The transmission system component 10 has a power input end and a power output end connected by a transmission link. The motor 30 is connected to the power input end via a connecting shaft, and the motor 30 can transmit power to the power input end, which in turn can transmit power to the power output end. The power output end is selectively connected to the wheel 20 via a first clutch C1, meaning it can be connected to or disconnected from the wheel 20. When the power output end is connected to the wheel 20 via the first clutch C1, it can transmit power to the wheel 20, thus enabling the motor 30 to output power. The engine 40 is selectively connected to the motor 30 via a second clutch C2, meaning it can be connected to or disconnected from the motor 30. When the engine 40 is connected to the motor 30 via the second clutch C2, it can transmit power to the power input end and also drive the motor 30 to generate electricity.

[0031] Continue to refer to Figure 1 The hybrid power system provided in this embodiment achieves different operating modes by controlling the switching of the working states of the first clutch C1 and the second clutch C2. The operating modes include range-extending power generation mode, pure electric drive mode and parallel drive mode.

[0032] Specifically, the power output terminal can be disconnected or connected to the wheel 20 by the first clutch C1, and the engine 40 can be disconnected or connected to the motor 30 by the second clutch C2. Different working modes can be achieved by controlling the switching of the working states of the first clutch C1 and the second clutch C2. The working modes include range-extending power generation mode, pure electric drive mode and parallel drive mode.

[0033] In some optional embodiments, in range-extended power generation mode, the power output terminal is disconnected from the wheel 20 via the first clutch C1, and the engine 40 is connected to the motor 30 via the second clutch C2. That is, in range-extended power generation mode, the power output terminal is disconnected from the wheel 20 via the first clutch C1, and the engine 40 is connected to the motor 30 via the second clutch C2. The engine 40 can drive the motor 30 to generate electricity, thereby realizing the range-extended power generation mode.

[0034] In some optional embodiments, in pure electric drive mode, the power output terminal is connected to the wheel 20 via a first clutch C1, and the engine 40 is disconnected from the motor 30 via a second clutch C2. That is, in pure electric drive mode, the power output terminal is connected to the wheel 20 via the first clutch C1, and the engine 40 is disconnected from the motor 30 via the second clutch C2. The motor 30 can transmit power to the power input terminal, which can then transmit power to the power output terminal, which in turn can transmit power to the wheel 20, thus enabling the motor 30 to output power and achieving pure electric drive mode.

[0035] In some optional embodiments, in parallel drive mode, the power output terminal is connected to the wheel 20 via a first clutch C1, and the engine 40 is connected to the motor 30 via a second clutch C2. That is, in parallel drive mode, the power output terminal is connected to the wheel 20 via the first clutch C1, and the engine 40 is connected to the motor 30 via the second clutch C2. Both the engine 40 and the motor 30 can transmit power to the power input terminal, which can then transmit power to the power output terminal, which in turn can transmit power to the wheel 20, thus achieving power output from the motor 30 and the engine 40, thereby realizing parallel drive mode.

[0036] In the hybrid power system provided in this embodiment, the transmission system component 10 has a power input end and a power output end connected by transmission. The power output end is selectively connected to the wheel 20 through a first clutch C1. The motor 30 is connected to the power input end through a connecting shaft, and the engine 40 is selectively connected to the motor 30 through a second clutch C2. This allows the hybrid power system to achieve three modes: range-extended power generation mode, pure electric drive mode, and parallel drive mode. Based on a single motor, the efficient conversion and transmission of power is achieved through the cooperation of the transmission system component 10, the first clutch C1, and the second clutch C2. Furthermore, the hybrid power system provided in this embodiment has a simple and compact structure. When used in vehicles, it can reduce the vehicle's size and weight, improve the vehicle's space utilization and handling performance, and also reduce manufacturing costs and improve production efficiency.

[0037] In existing technologies, installing an air conditioning compressor in a hybrid power system requires an additional motor and controller, which increases costs. Furthermore, increasing the power of the electric air conditioning compressor necessitates a high-power motor, drastically increasing costs.

[0038] The hybrid power system provided in this embodiment of the present disclosure also includes an air conditioning compressor 50, which is selectively connected to the motor 30 via a third clutch C3.

[0039] Specifically, in the hybrid power system provided in this embodiment, the air conditioning compressor 50 is selectively connected to the motor 30 via a third clutch C3. This means that the air conditioning compressor 50 can be connected to the motor 30 via the third clutch C3, or it can be disconnected from the motor 30 via the third clutch C3. When the air conditioning compressor 50 is connected to the motor 30 via the third clutch C3, the motor 30 can directly provide power to the air conditioning compressor 50, meeting the high power requirements of the air conditioning compressor 50. Simultaneously, this further achieves a compact structure for the hybrid power system. When used in a vehicle, it can reduce the vehicle's size and weight, improve space utilization and handling performance, and also reduce manufacturing costs and increase production efficiency.

[0040] Continue to refer to Figure 1 In some alternative embodiments, the hybrid power system achieves different air conditioning modes by controlling the switching of the working state of the third clutch C3, including an air conditioning on mode and an air conditioning off mode.

[0041] When the air conditioner is in operation, the air conditioner compressor 50 is connected to the motor 30 via the third clutch C3;

[0042] When the air conditioner is off, the air conditioner compressor 50 is disconnected from the motor 30 via the third clutch C3.

[0043] Specifically, the air conditioning compressor 50 can be disconnected or connected to the motor 30 via the third clutch C3. This allows for switching the operating state of the third clutch C3 to achieve different air conditioning modes, including an air conditioning on mode and an air conditioning off mode. In the air conditioning on mode, the air conditioning compressor 50 is connected to the motor 30 via the third clutch C3, and the motor 30 can directly provide power to the air conditioning compressor 50, meeting the high power requirements of the air conditioning compressor 50. In the air conditioning off mode, the motor 30 is not required to provide power to the air conditioning compressor 50, and the air conditioning compressor 50 is disconnected from the motor 30 via the third clutch C3.

[0044] Optionally, in different operating modes, namely, in any of the range-extended generation mode, pure electric drive mode, and parallel drive mode, either the air conditioning on mode or the air conditioning off mode can be activated. In the parking mode, that is, when the first clutch C1 controls the power output end to disconnect from the wheel 20 and the second clutch C2 controls the engine 40 to disconnect from the motor 30, either the air conditioning on mode or the air conditioning off mode can also be activated.

[0045] Figure 2 This is a schematic diagram of another hybrid power system provided in this disclosure embodiment, with reference to... Figure 2In some embodiments, the transmission system assembly 10 includes a planetary gear train assembly 11. The planetary gear train assembly 11 has a compact structure, which can help to achieve a compact structure of the hybrid power system. When used in a vehicle, it can reduce the size and weight of the vehicle, improve the space utilization and handling performance of the vehicle, and reduce manufacturing costs and improve production efficiency.

[0046] Figure 3 yes Figure 2 The lever diagram of the planetary gear train assembly in the hybrid power system is shown in the reference diagram. Figure 2 and Figure 3 In some embodiments, the planetary gear train assembly 11 includes a sun gear S, a planet gear PG, a planet carrier PC, and a ring gear R. The planet gear PG is rotatably disposed on the planet carrier PC and meshes between the sun gear S and the ring gear R. The sun gear S is the power input end, the ring gear R is the power output end, and the planet carrier PC is connected to the wheel 20 in a transmission connection.

[0047] Specifically, in the hybrid power system provided in this embodiment, when the transmission system component 10 includes a planetary gear train component 11, the planetary gear train component 11 includes a sun gear S, planet gears PG, a planet carrier PC, and a ring gear R. The sun gear S is the power input end, i.e., the motor 30 is connected to the sun gear S, and the motor 30 can drive the sun gear S to rotate. The ring gear R is the power output end. The planet carrier PC is connected to the wheel 20. The first clutch C1 can achieve selective connection between the planet carrier PC and the ring gear R, thereby achieving selective connection between the wheel 20 and the ring gear R. When the wheel 20 is connected to the ring gear R through the first clutch C1, the motor 30 can transmit power to the wheel 20 through the planetary gear train component 11. When the wheel 20 is disconnected from the ring gear R through the first clutch C1, the motor 30 cannot transmit power to the wheel 20.

[0048] In one configuration, the gear ring R is disconnected from the wheel 20 via the first clutch C1, and the engine 40 is connected to the motor 30 via the second clutch C2. The engine 40 can drive the motor 30 to generate electricity, thus achieving a range-extended power generation mode. Alternatively, the gear ring R can be connected to the wheel 20 via the first clutch C1, and the engine 40 can be disconnected from the motor 30 via the second clutch C2. The motor 30 can then transmit power to the wheel 20, achieving power output from both the motor 30 and the engine 40, thus achieving a pure electric drive mode. Finally, the gear ring R can be connected to the wheel 20 via the first clutch C1, and the engine 40 can be connected to the motor 30 via the second clutch C2. Both the engine 40 and the motor 30 can transmit power to the wheel 20, achieving power output from both the motor 30 and the engine 40, thus achieving a parallel drive mode.

[0049] Continue to refer to Figure 2 and Figure 3In some embodiments, the air conditioning compressor 50 is selectively connected to the sun gear S via a third clutch C3.

[0050] Specifically, in the hybrid power system provided in this embodiment, the air conditioning compressor 50 is selectively connected to the sun gear S via a third clutch C3, and the motor 30 is connected to the sun gear S. This allows for selective connection between the air conditioning compressor 50 and the motor 30 via the third clutch C3, enabling both connection and disconnection. When the air conditioning compressor 50 is connected to the motor 30 via the third clutch C3, the motor 30 can directly provide power to the air conditioning compressor 50, meeting its high-power requirements. Furthermore, this design further optimizes the compactness of the hybrid power system, reducing vehicle size and weight, improving space utilization and handling performance, and lowering manufacturing costs while increasing production efficiency.

[0051] Figure 4 This is a schematic diagram of another hybrid power system provided in this disclosure embodiment, with reference to... Figure 4 In some embodiments, the drivetrain assembly 10 includes a parallel-shaft transmission 12. The parallel-shaft transmission 12 is less expensive, and its use can help reduce production costs.

[0052] Continue to refer to Figure 4 In some embodiments, the parallel shaft transmission 12 includes a first gear train 121, and a first main shaft 122 and a second main shaft 123 connected to the first gear train 121. The first main shaft 122 and the second main shaft 123 are parallel. The first main shaft 122 is the power input end, and the second main shaft 123 is the power output end. The engine 40 is selectively connected to the second main shaft 123 through the second clutch C2.

[0053] Specifically, in the hybrid power system provided in this embodiment, when the transmission system component 10 includes a parallel shaft transmission 12, the parallel shaft transmission 12 includes a first gear train 121, and a first main shaft 122 and a second main shaft 123 connected to the first gear train 121. The first main shaft 122 is the power input end, and the second main shaft 123 is the power output end. That is, the motor 30 is connected to the first main shaft 122, and the motor 30 can drive the first main shaft 122 to rotate. The second main shaft 123 is selectively connected to the wheel 20 through a first clutch C1. When the second main shaft 123 is connected to the wheel 20 through the first clutch C1, the motor 30 can transmit power to the first main shaft 122, and the power can be transmitted to the second main shaft 123 through the first gear train 121. The second main shaft 123 can then transmit power to the wheel 20. When the second main shaft 123 is disconnected from the wheel 20 through the first clutch C1, the motor 30 cannot transmit power to the wheel 20.

[0054] In one configuration, the second main shaft 123 is disconnected from the wheel 20 via the first clutch C1, and the engine 40 is connected to the second main shaft 123 via the second clutch C2. The engine 40 and the motor 30 are connected via a parallel shaft transmission 12. The engine 40 can drive the motor 30 to generate electricity, thus achieving a range-extended power generation mode. Alternatively, the second main shaft 123 can be connected to the wheel 20 via the first clutch C1, and the engine 40 can be disconnected from the second main shaft 123 via the second clutch C2. The motor 30 can then transmit power to the wheel 20, achieving power output from the motor 30, thus achieving a pure electric drive mode. Finally, the second main shaft 123 can be connected to the wheel 20 via the first clutch C1, and the engine 40 can be connected to the second main shaft 123 via the second clutch C2. Both the engine 40 and the motor 30 can transmit power to the wheel 20, achieving power output from both the motor 30 and the engine 40, thus achieving a parallel drive mode.

[0055] In some embodiments, the parallel shaft transmission 12 further includes a third main shaft 124, which is connected to the first gear train 121 and is parallel to the first main shaft 122. The air conditioning compressor 50 is selectively connected to the third main shaft 124 via a third clutch C3.

[0056] Specifically, in the hybrid power system provided in this embodiment, the air conditioning compressor 50 is selectively connected to the third main shaft 124 via a third clutch C3, and the motor 30 is connected to the first main shaft 122. Both the first main shaft 122 and the third main shaft 124 are connected to the first gear system 121. The air conditioning compressor 50 can be selectively connected to the third main shaft 124 via the third clutch C3, which also allows for selective connection between the air conditioning compressor 50 and the motor 30. Alternatively, the air conditioning compressor 50 can be connected to the motor 30 via the third clutch C3, or disconnected from the motor 30. When the air conditioning compressor 50 is connected to the motor 30 via the third clutch C3, the motor 30 can directly provide power to the air conditioning compressor 50, meeting the high power requirements of the air conditioning compressor 50. Simultaneously, this further achieves a compact hybrid power system structure. When used in a vehicle, it can reduce the vehicle's size and weight, improve space utilization and handling performance, and also reduce manufacturing costs and increase production efficiency.
