Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle technical field especially drive assembly and vehicle. BACKGROUND

[0002] The hybrid vehicle usually includes an engine and a motor, both of which can drive the vehicle to move. In order to improve the endurance of the hybrid vehicle, a generator is generally arranged in the hybrid vehicle. When the vehicle stops running, the generator is driven to work by the engine, thereby generating electric energy to charge the battery of the vehicle and improve the endurance of the vehicle. However, the charging rate of the motor by this method is slow. SUMMARY

[0003] The utility model discloses a drive assembly and vehicle, and aims at improving the charging rate of the vehicle.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] In a first aspect of the present application, a drive assembly is provided, comprising an engine, a generator, a drive motor and a first engagement and separation assembly. The generator is in driving connection with the engine. The drive motor is in driving connection with the engine. The first engagement and separation assembly is used to couple or disconnect the connection between the drive motor and the first wheel. When the vehicle is in the parking power generation mode, the first engagement and separation assembly is controlled to disconnect the power connection between the drive motor and the first wheel, and the power transmission of the engine is controlled to be transmitted to the generator and the drive motor to realize double-motor power generation. Through the above arrangement, when it is necessary to charge the vehicle, the first engagement and separation assembly can be used to disconnect the connection between the drive motor and the first wheel. In this way, during the operation of the engine, the engine can transmit power to the drive motor without transmitting power to the first wheel, so that the drive motor can generate power as a power generation device. At the same time, the engine can also drive the generator to work to make the generator generate power.

[0006] In this way, when the vehicle is in the parking power generation mode, the drive motor and the generator can generate power at the same time to provide electric energy for the vehicle. Compared with the method of driving the generator to generate power only by the engine, the rate of generating electric energy by the drive assembly can be improved, thereby accelerating the charging rate of the vehicle.

[0057] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0058] This application provides a vehicle, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the external structure of a vehicle provided in an embodiment of this application. The vehicle 100 includes a body 10 and wheels. The wheels are connected to the body 10, and the wheels rotate to drive the body 10 to move, thereby realizing the driving function of the vehicle 100.

[0059] like Figure 1 As shown, the vehicle 100 also includes a drive assembly 20, which is connected to the body 10. The drive assembly 20 is used to drive the wheels to rotate, thereby causing the body 10 to move. Thus, the vehicle 100 can be driven to move by the drive assembly 20.

[0060] For example, the drive assembly 20 can be connected to the front end of the vehicle 100 to drive the wheels located at the front end of the vehicle 100 to rotate, in which case the vehicle 100 is a front-drive vehicle 100.

[0061] For example, the drive assembly 20 can be connected to the rear end of the vehicle 100 to drive the wheels located at the rear end of the vehicle 100 to rotate, in which case the vehicle 100 is a rear-drive vehicle 100.

[0062] For example, there can be two drive assemblies 20 and four wheels. The two drive assemblies 20 are connected to the front and rear ends of the vehicle 100 respectively to drive the two wheels at the front end of the vehicle 100 and the two wheels at the rear end of the vehicle 100 to rotate. At this time, the vehicle 100 is a four-wheel drive vehicle 100.

[0063] Based on this, in some embodiments, such as Figure 2 As shown, Figure 2 for Figure 1 The diagram shows the structure of the drive assembly 20 including the second engagement / disengagement component 2, and the wheels include a first wheel 30 and a second wheel 40.

[0064] For example, the drive assembly 20 may be connected only to the first wheel 30 to drive the vehicle 100 to move by rotating the first wheel 30.

[0065] For example, the drive assembly 20 is connected to both the first wheel 30 and the second wheel 40 in a transmission manner.

[0066] In this way, the drive assembly 20 can simultaneously drive the first wheel 30 and the second wheel 40 to rotate, thereby driving the vehicle 100 to move more stably.

[0067] In some embodiments, such as Figure 2 As shown, the drive assembly 20 includes an engine 8, a generator 9, and a drive motor 111. The generator 9 is driveably connected to the engine 8. The drive motor 111 is driveably connected to the engine 8.

[0068] The drive assembly 20 also includes a first engagement / disengagement component 1, which is used to couple or disconnect the drive motor 111 from the first wheel 30.

[0069] When the vehicle 100 is in the parking power generation mode, the first engagement / disengagement assembly 1 is controlled to disconnect the power connection between the drive motor 111 and the first wheel 30, and the power of the engine 8 is controlled to be transmitted to the generator 9 and the drive motor 111 to achieve dual-motor power generation.

[0070] For example, the first engagement / disengagement assembly 1 may include a clutch, or it may include a hydraulic torque converter, etc. Other engagement / disengagement assemblies described below are the same as the first engagement / disengagement assembly 1, and may include a clutch or a hydraulic torque converter, etc.

[0071] It should be noted that the vehicle 100 also includes a battery, which is connected to the drive assembly 20 and is used to provide electrical energy to the drive assembly 20 or store the electrical energy generated by the drive assembly 20.

[0072] With the above configuration, when the vehicle 100 needs to be charged, the drive motor 111 and the first wheel 30 can be disconnected through the first engagement / disengagement component 1. Thus, during the operation of the engine 8, the engine 8 can transmit power to the drive motor 111 but not to the first wheel 30, allowing the drive motor 111 to act as a generator. At the same time, the engine 8 can also drive the generator 9 to operate, enabling the generator 9 to generate electricity.

[0073] In this way, when the vehicle 100 is in the parking power generation mode, the drive motor 111 and the generator 9 can generate electricity simultaneously to provide power to the vehicle 100. Compared with the generator 9 being driven by the engine 8 alone, this can increase the rate at which the drive assembly 20 generates electricity, thereby speeding up the charging rate of the vehicle 100.

[0074] In addition, when it is necessary to drive the vehicle 100 by the drive motor 111, the drive motor 111 and the first wheel 30 can be connected by the first engagement and disengagement assembly 1. This allows the drive motor 111 to work and transmit power to the first wheel 30 to drive the first wheel 30 to rotate, thereby realizing the driving function of the drive motor 111 on the vehicle 100.

[0075] Specifically, the first coupling / separation component 1 has a first coupling state and a first separation state.

[0076] When the first engagement / disengagement component 1 is in the first coupling state, the drive motor 111 is connected to the first wheel 30 in a transmission connection to drive the first wheel 30 to rotate.

[0077] The drive motor 111 is disconnected from the first wheel 30, and the engine 8 operates to drive the generator 9 and the drive motor 111 to generate electricity simultaneously, so that the vehicle 100 is in the parking power generation mode.

[0078] In this way, by switching the first engagement / disengagement component 1 between the first coupling state and the first disengagement state, the drive motor 111 can generate electricity through the engine 8, or drive the first wheel 30 to rotate through the drive motor 111. This ensures the driving function of the drive assembly 20 while increasing the rate at which the drive assembly 20 generates electrical energy and improving the working performance of the drive assembly 20.

[0079] In some other embodiments, the engine 8 is driven to the drive motor 111 via the first engagement / disengagement assembly 1, such that the drive motor 111 is driven to one of the engine 8 and the first wheel 30 via the first engagement / disengagement assembly 1, while being disconnected from the other.

[0080] With the above settings, when the vehicle 100 needs to be charged, the engine 8 can be connected to the drive motor 111 through the first engagement / disengagement component 1, and the drive motor 111 can be disconnected from the first wheel 30, so that the engine 8 can transmit power to the drive motor 111 and generate electricity.

[0081] When the vehicle 100 needs to be driven by the drive motor 111, the engine 8 can be disconnected from the drive motor 111 by the first engagement / disengagement component 1, and the drive motor 111 can be connected to the first wheel 30 in a transmission manner. At this time, the drive motor 111 works to transmit power to the first wheel 30 and will not transmit power to the engine 8, so as to drive the first wheel 30 to rotate by the drive motor 111, thereby realizing the driving function of the drive assembly 20.

[0082] Specifically, the first coupling / separation component 1 has a second coupling state and a third coupling state.

[0083] When the first engagement / disengagement assembly 1 is in the second coupling state, the drive motor 111 is connected to the first wheel 30 in transmission and disconnected from the engine 8 to drive the first wheel 30 to rotate.

[0084] When the first engagement / disengagement component 1 is in the third coupling state, the drive motor 111 is disconnected from the first wheel 30 and connected to the engine 8 in a transmission manner. The engine 8 operates to drive the engine 8 and the drive motor 111 to generate electricity simultaneously, so that the vehicle 100 is in a parking power generation mode.

[0085] In this way, by switching the first engagement / disengagement component 1 between the second coupling state and the third coupling state, the drive motor 111 can generate electricity through the engine 8, or drive the first wheel 30 to rotate through the drive motor 111. This ensures the driving function of the drive assembly 20 while increasing the rate at which the drive assembly 20 generates electrical energy and improving the working performance of the drive assembly 20.

[0086] In some embodiments, such as Figure 2 As shown, the first engagement / disengagement assembly 1 includes a first clutch 11, a second clutch 12 and a third clutch 13. The first clutch 11 is connected to the engine 8, the third clutch 13 is connected to the first wheel 30, and the second clutch 12 is connected to the drive motor 111.

[0087] The second clutch 12 is located between the first clutch 11 and the third clutch 13, and can move between the first clutch 11 and the third clutch 13 to switch between the second coupling state and the third coupling state.

[0088] For example, the first clutch 11, the second clutch 12, and the third clutch 13 can all be friction plates, or the first clutch 11, the second clutch 12, and the third clutch 13 can all be connecting keys, etc.

[0089] With the above configuration, when the first clutch 11 and the second clutch 12 are connected, the engine 8 can transmit power to the drive motor 111 through the first clutch 11 and the second clutch 12, thereby enabling the drive motor 111 to generate electricity. When the second clutch 12 and the third clutch 13 are connected, the drive motor 111 can be connected to the first wheel 30, thereby enabling the drive motor 111 to drive the first wheel 30 to rotate, realizing the driving function of the drive motor 111.

[0090] In this way, compared to setting a clutch between the engine 8 and the drive motor 111, and a clutch between the drive motor 111 and the first wheel 30, when the first engagement / disengagement assembly 1 includes a first clutch 11, a second clutch 12 and a third clutch 13, the drive motor 111 can be connected to one of the engine 8 and the first wheel 30 and disconnected from the other simply by moving the second clutch 12. This simplifies the structure of the first engagement / disengagement assembly 1 and makes it easier to set up.

[0091] Based on this, in some embodiments, such as Figure 2 As shown, the drive assembly 20 also includes a second engagement / disengagement assembly 2, which is drive-connected between the second clutch 12 and the first wheel 30.

[0092] The second engagement / disengagement assembly 2 has a first engagement state and a first disengagement state. When the second engagement / disengagement assembly 2 is in the first engagement state, the second clutch 12 is connected to the first wheel 30 in a transmission connection. When the second engagement / disengagement assembly 2 is in the first disengagement state, the second clutch 12 is disconnected from the first wheel 30.

[0093] In this way, the engagement and disengagement of the engine 8 and the drive motor 111 can be changed by altering the states of the second engagement and disengagement component 2 and the first engagement and disengagement component 1, thereby enabling the drive assembly 20 to perform different functions.

[0094] Specifically, when the first engagement / disengagement assembly 1 is in the third coupling state and the second engagement / disengagement assembly 2 is in the first engagement state, at least one of the engine 8 and the drive motor 111 operates, transmitting power sequentially through the second clutch 15 and the second engagement / disengagement assembly 2 to the first wheel 30 to drive the first wheel 30 to rotate.

[0095] In this way, the first wheel 30 can be driven to rotate by at least one of the engine 8 and the drive motor 111, thereby driving the vehicle 100 to move.

[0096] Alternatively, in the above-mentioned case, the engine 8 can operate independently, transmitting power to the drive motor 111 through the second clutch 12, so that the drive motor 111 generates electricity and transmits the power to the first wheel 30 through the second clutch 12 and the second engagement / disengagement assembly 2, so as to drive the first wheel 30 to rotate.

[0097] In this way, while the engine 8 drives the first wheel 30 to rotate, that is, while the engine 8 drives the vehicle 100 to move, the engine 8 can also transmit power to the drive motor 111, thereby enabling the drive motor 111 to generate electricity.

[0098] In some embodiments, such as Figure 2As shown, the drive assembly 20 also includes a first driveshaft 101, a second driveshaft 102, and a first differential 103. The first driveshaft 101 is connected to the first wheel 30 and to the third clutch 13. The second driveshaft 102 is connected to the second wheel 40. The first differential 103 is connected between the first driveshaft 101 and the second driveshaft 102 and is connected to the second engagement / disengagement assembly 2.

[0099] In this way, by setting the first differential 103, the engine 8 can drive the first wheel 30 and the second wheel 40 to rotate simultaneously, so as to drive the vehicle 100 to move more stably.

[0100] Specifically, when the first engagement / disengagement assembly 1 is in the third coupling state and the second engagement / disengagement assembly 2 is in the first engagement state, at least one of the engine 8 and the drive motor 111 operates, transmitting power sequentially through the second clutch 15, the second engagement / disengagement assembly 2, and the first differential 103 to the first drive shaft 101 and the second drive shaft 102, thereby driving the first wheel 30 and the second wheel 40 to rotate. Furthermore, during vehicle 100 cornering, the rotational speeds of the first wheel 30 and the second wheel 40 are automatically adjusted to ensure stable vehicle 100 operation.

[0101] In some embodiments, the first engagement / disengagement assembly 1 also has a second disengagement state. When the first engagement / disengagement assembly 1 is in the second disengagement state, the second clutch 12 is disconnected from the first clutch 11 and from the third clutch 13.

[0102] When the second engagement / disengagement assembly 2 is in the first engagement state and the first engagement / disengagement assembly 1 is in the second disengagement state, the drive motor 111 operates and transmits power sequentially through the second clutch 15, the second engagement / disengagement assembly 2, the first differential 103, and the first drive shaft 101 to the first wheel 30 and the second wheel 40, so as to drive the first wheel 30 and the second wheel 40 to rotate.

[0103] In this way, the drive motor 111 can work independently, thereby transmitting power to the first drive shaft 101 and the second drive shaft 102 through the first differential 103, so that the drive motor 111 can drive the first wheel 30 and the second wheel 40 to rotate independently, so that the drive assembly 20 can output power more stably when the drive motor 111 works alone, thereby making the vehicle 100 drive stably.

[0104] Based on the above, in some embodiments, such as Figure 2 As shown, the drive assembly 20 also includes a third engagement / disengagement component 3, which is connected to the generator 9 and adapted to be connected to the second wheel 40 so that the generator 9 can be connected to or disconnected from the second wheel 40 in a transmission manner.

[0105] With the above settings, during the process of generating electricity by the generator 9 driven by the engine 8, the generator 9 can be disconnected from the second wheel 40 by the third engagement / disengagement component 3, so as to prevent the power transmitted from the engine 8 to the generator 9 from being transmitted to the second wheel 40, thus ensuring the power generation rate of the generator 9.

[0106] By connecting the generator 9 to the second wheel 40 via the third engagement / disengagement assembly 3, the generator 9 can act as a drive device to transmit power to the second wheel 40, thereby driving the second wheel 40 to rotate.

[0107] Specifically, the third coupling separation component 3 has a fourth coupling state and a fifth coupling state.

[0108] When the third engagement / disengagement component 3 is in the fourth coupling state, the generator 9 is connected to the second wheel 40 in transmission and disconnected from the engine 8 to drive the second wheel 40 to rotate.

[0109] In this way, the generator 9 can be used as a drive unit to transmit power to the second wheel 40 to drive the vehicle 100, thus improving the applicability of the drive assembly 20.

[0110] When the third engagement / disengagement component 3 is in the fifth coupling state, the generator 9 is disconnected from the second wheel 40 and connected to the engine 8. The engine 8 operates to drive the generator 9 and the drive motor 111 to generate electricity simultaneously, thereby ensuring the power generation function of the generator 9 and putting the vehicle 100 in the parking power generation mode.

[0111] In some embodiments, such as Figure 2 As shown, the third engagement / disengagement assembly 3 includes a fourth clutch 31, a fifth clutch 32, and a sixth clutch 33. The fourth clutch 31 is connected to the engine 8, the sixth clutch 33 is connected to the second wheel 40, and the fifth clutch 32 is connected to the generator 9.

[0112] The fifth clutch 32 is located between the fourth clutch 31 and the sixth clutch 33, and is movable between the fourth clutch 31 and the sixth clutch 33 to switch between the fourth coupling state and the fifth coupling state.

[0113] For example, the fourth clutch 31, the fifth clutch 32, and the sixth clutch 33 can all be friction plates, or the fourth clutch 31, the fifth clutch 32, and the sixth clutch 33 can all be connecting keys, etc.

[0114] With the above configuration, when the fourth clutch 31 and the fifth clutch 32 are connected, the engine 8 can transmit power to the generator 9 through the fourth clutch 31 and the fifth clutch 32, thereby enabling the generator 9 to generate electricity. When the fifth clutch 32 and the sixth clutch 33 are connected, the generator 9 can be connected to the second wheel 40 for transmission, thereby enabling the generator 9 to drive the second wheel 40 to rotate and realize the driving function of the generator 9.

[0115] In this way, compared to setting a clutch between the engine 8 and the generator 9, and a clutch between the generator 9 and the second wheel 40, when the third engagement / disengagement assembly 3 includes a fourth clutch 31, a fifth clutch 32 and a sixth clutch 33, the generator 9 can be connected to one of the engine 8 and the second wheel 40 and disconnected from the other simply by moving the fifth clutch 32. This simplifies the structure of the third engagement / disengagement assembly 3 and makes it easier to set up.

[0116] In some embodiments, when the third engagement / disengagement component 3 is in a fourth coupled state, the second engagement / disengagement component 2 is in a first disconnected state, and the first engagement / disengagement component 1 is in a second coupled state, the generator 9 operates, transmitting power sequentially through the fifth clutch 32 and the second drive shaft 102 to the second wheel 40 to drive the second wheel 40 to rotate. The drive motor 111 operates, transmitting power sequentially through the second clutch 12 and the first drive shaft 101 to the first wheel 30 to drive the first wheel 30 to rotate.

[0117] With the above configuration, the generator 9 can drive the second wheel 40 independently, while the drive motor 111 can drive the first wheel 30 independently.

[0118] In this way, power can be output through generator 9 and drive motor 111, and the power transmitted to the first wheel 30 and the second wheel 40 can be adjusted separately according to the power requirements of the first wheel 30 and the second wheel 40, thereby meeting the power requirements of the first wheel 30 and the second wheel 40 under different conditions. This can improve the working performance of drive assembly 20 and improve the applicability of drive assembly 20.

[0119] In some examples, such as Figure 3 As shown, the drive assembly 20 also includes a first reducer 105, a second reducer 106, and a third reducer 107.

[0120] The first reducer 105 is connected between the third clutch 13 and the first drive shaft 101 to increase the magnitude of the torque transmitted to the first drive shaft 101 through the third clutch 13.

[0121] The second reducer 106 is connected between the sixth clutch 33 and the second drive shaft 102 to increase the torque transmitted to the second drive shaft 102 through the sixth clutch 33.

[0122] The third reducer 107 is connected between the second engagement / disengagement assembly 2 and the first differential 103 to increase the amount of torque transmitted to the first differential 103 through the second engagement / disengagement assembly 2.

[0123] In some other embodiments, such as Figure 3 As shown, Figure 1 for Figure 3 A schematic diagram of the drive assembly 20 including the fourth engagement / disengagement component 4. Compared with the above embodiment, this embodiment omits the second engagement / disengagement component 2. In this embodiment, the drive assembly 20 also includes a transmission component 112 and the fourth engagement / disengagement component 4.

[0124] The transmission assembly 112 is connected to the first differential 103.

[0125] The fourth engagement / disengagement assembly 4 is connected between the engine 8 and the transmission assembly 112. The fourth engagement / disengagement assembly 4 has a second engaged state and a second disengaged state. When the fourth engagement / disengagement assembly 4 is in the second engaged state, the engine 8 is drive-connected to the transmission assembly 112. When the fourth engagement / disengagement assembly 4 is in the second disengaged state, the engine 8 is disengaged from the transmission assembly 112.

[0126] With the above settings, the fourth engagement / disengagement assembly 4 can be in the second engagement state. At this time, the engine 8 is working and transmits power sequentially through the fourth engagement / disengagement assembly 4, the first transmission component and the first differential 103 to the first drive shaft 101 and the second drive shaft 102, thereby driving the first wheel 30 and the second wheel 40 to rotate, so as to drive the vehicle 100 to travel.

[0127] In some embodiments, the fourth clutch 31 is connected to the engine 8, and the sixth clutch 33 is connected to the transmission assembly 112. The first clutch 11 is connected to the engine 8, and the third clutch 13 is connected to the transmission assembly 112.

[0128] When the first engagement / disengagement component 1 is in the second coupling state, the third engagement / disengagement component 3 is in the fifth coupling state, and the fourth engagement / disengagement component 4 is in the second disconnection state, the engine 8 operates, transmitting power to the drive motor 111 through the second clutch 12 to generate electricity, and transmitting power to the generator 9 through the fifth clutch 32 to generate electricity, thus putting the vehicle 100 into the parking power generation mode.

[0129] In this way, since the first engagement / disengagement component 1 is in the second coupling state, the third engagement / disengagement component 3 is in the fifth coupling state, and the fourth engagement / disengagement component 4 is in the second disconnection state, the drive motor 111, the generator 9, and the engine 8 are all disconnected from the transmission component 112. At this time, the power transmitted by the engine 8 can be transmitted to the drive motor 111 and the generator 9 simultaneously, thereby enabling the drive motor 111 and the generator 9 to generate electricity.

[0130] In some examples, such as Figure 3 As shown, the transmission assembly 112 includes a third transmission shaft 109, on which a plurality of transmission parts 1091 are provided.

[0131] The sixth clutch 33 is connected to a transmission part 1091, the third clutch 13 is connected to a transmission part 1091, and the fourth engagement / disengagement assembly 4 is connected to a transmission part 1091.

[0132] For example, the transmission part 1091 can be a transmission gear, transmission belt, etc.

[0133] In some embodiments, such as Figure 4 As shown, a fourth reducer 108 is formed between the third drive shaft 109 and the first differential 103 to increase the torque transmitted to the first differential 103.

[0134] In other embodiments, such as Figure 4 As shown, Figure 1 for Figure 5 Another structural diagram of the drive assembly 20 including the fourth engagement / disengagement component 4, wherein the fourth clutch 31 is connected to the engine 8 and to the first clutch 11, the third clutch 13 is connected to the sixth clutch 33 and to the transmission assembly 112.

[0135] With the above settings, during the operation of engine 8, power can be transmitted to generator 9 first, and then to drive motor 111. This also enables engine 8 to drive generator 9 and drive motor 111 to generate electricity simultaneously.

[0136] Specifically, when the first engagement / disengagement component 1 is in the second coupling state, the third engagement / disengagement component 3 is in the fifth coupling state, and the fourth engagement / disengagement component 4 is in the second disconnection state, the engine 8 operates, transmitting power to the generator 9 through the fifth clutch 32 to generate electricity, and transmitting power to the drive motor 111 through the fifth clutch 32 and the second clutch 12 to generate electricity.

[0137] In this way, during the operation of engine 8, after power is transmitted to the fifth clutch 32, some power will be directly transmitted to generator 9 to generate electricity, while the other part will continue to be transmitted to the second clutch 12 and then to drive motor 111 to generate electricity.

[0138] In the above embodiments, the first engagement / disengagement assembly 1 includes a first clutch 11, a second clutch 12, and a third clutch 13.

[0139] In other embodiments, such as Figure 5 As shown, Figure 1 for Figure 5 The schematic diagram of the drive assembly 20 excluding the seventh engagement / disengagement component 7 shows that the first engagement / disengagement component 1 includes a first clutch 14 and a second clutch 15. The first clutch 14 is located between the engine 8 and the drive motor 111, and the second clutch 15 is located between the drive motor 111 and the first wheel 30.

[0140] With the above settings, the states of the first clutch 14 and the second clutch 15 can be adjusted so that the drive motor 111 is connected to one of the engine 8 and the first wheel 30, and disconnected from the other. Thus, when the drive motor 111 is connected to the engine 8, the drive motor 111 generates electricity through the engine 8, and when the drive motor 111 is connected to the first wheel 30, the drive motor 111 drives the first wheel 30 to rotate, thereby realizing the power generation and driving functions of the drive motor 111.

[0141] Specifically, when the first clutch 14 is engaged and the second clutch 15 is disengaged, the engine 8 is connected to the drive motor 111 in a transmission connection. The engine 8 operates and transmits power to the drive motor 111 through the first clutch 14, so that the drive motor 111 generates electricity, thereby realizing the power generation function of the drive motor 111.

[0142] When the first clutch 14 is in the disengaged state and the second clutch 15 is in the engaged state, the drive motor 111 operates, transmitting power to the first wheel 30 through the second clutch 15 to drive the first wheel 30 to rotate, thereby realizing the driving function of the drive motor 111.

[0143] In some embodiments, such as Figure 5 As shown, the drive assembly 20 also includes a second differential 104 and a fifth engagement / disengagement assembly 5.

[0144] The second differential 104 is connected between the first drive shaft 101 and the second drive shaft 102, and is connected to the first clutch 14.

[0145] The fifth engagement / disengagement assembly 5 is connected between the first drive shaft 101 and the second drive shaft 102. The fifth engagement / disengagement assembly 5 has a third engagement state and a third disengagement state.

[0146] When the fifth engagement / disengagement assembly 5 is in the third engagement state, the first clutch 14 is in the engagement state, and the second clutch 15 is in the disengagement state, the engine 8 is connected to the drive motor 111 in a transmission connection.

[0147] When the fifth engagement / disengagement assembly 5 is in the third disengagement state, the first clutch 14 is in the disengagement state, and the second clutch 15 is in the engagement state, the drive motor 111 is connected to the first wheel 30 in a transmission connection.

[0148] With the above settings, when the fifth engagement / disengagement component 5 is in the third disconnected state, the first drive shaft 101 and the second drive shaft 102 are connected through the second differential 104. At this time, the first drive shaft 101 and the second drive shaft 102 can rotate relative to each other to realize the differential function of the differential on the first wheel 30 and the second wheel 40.

[0149] When the fifth engagement / disengagement component 5 is in the third engagement state, the first drive shaft 101 and the second drive shaft 102 are rigidly connected through the fifth engagement / disengagement component 5, and the first drive shaft 101 and the second drive shaft 102 cannot rotate relative to each other, thus making the second differential 104 rigidly connected to the first drive shaft 101 and the second drive shaft 102.

[0150] In this way, during the operation of engine 8, engine 8 can transmit power to drive motor 111 in sequence through first clutch 14, second differential 104 and first drive shaft 101, thereby enabling drive motor 111 to generate electricity and realize the power generation function of drive motor 111.

[0151] In some embodiments, such as Figure 5 As shown, the second differential 104 includes a ring gear 1041, a planetary carrier 1043, planetary gears 1042, and an output gear 1044. The ring gear 1041 is drive-connected to the first clutch 14. The planetary carrier 1043 is connected to the first drive shaft 101. The planetary gear 1042 is disposed within the ring gear 1041 and meshes with it. The planetary gear 1042 is rotatably connected to the planetary carrier 1043. The output gear 1044 is connected to the second drive shaft 102 and meshes with the planetary gear 1042.

[0152] For example, the number of planetary gears 1042 can be one or more, such as two, three, four, etc.

[0153] With the above configuration, when the first clutch 14 is engaged, the fifth engagement / disengagement assembly 5 is in the third disengagement state, and the second clutch 15 is engaged, the engine 8 operates, transmitting power to the gear ring 1041 through the first clutch 14, thereby driving the gear ring 1041 to rotate. When the first wheel 30 and the second wheel 40 rotate at the same speed, that is, when the vehicle 100 is traveling in a straight line, the gear ring 1041 can transmit part of the power sequentially through the planetary gear 1042, the planet carrier 1043, the first drive shaft 101, and the second clutch 15 to the first wheel 30 to drive the first wheel 30 to rotate, and transmit another part of the power sequentially through the planetary gear 1042, the output gear 1044, and the second drive shaft 102 to the second wheel 40 to drive the second wheel 40 to rotate.

[0154] It is understandable that during the above process, the planetary gear 1042, the output gear 1044, and the gear ring 1041 are relatively stationary.

[0155] When a speed difference is generated between the first wheel 30 and the second wheel 40, and the first wheel 30 and the second wheel 40 rotate relative to each other, that is, when the vehicle 100 turns, the planetary gear 1042 can rotate relative to the planetary carrier 1043 while rotating with the planetary carrier 1043. In this way, the first drive shaft 101 connected to the second drive shaft 102 can rotate relative to the first drive shaft 101 connected to the planetary carrier 1043, thereby realizing the differential function of the second differential 104.

[0156] It should be noted that when a speed difference is generated between the first wheel 30 and the second wheel 40, the rotation of the planetary gear 1042 relative to the planet carrier 1043 is automatic.

[0157] In some embodiments, such as Figure 5 As shown, the fifth engagement / disengagement assembly 5 is located between the output gear 1044 and the planet carrier 1043.

[0158] With the above configuration, compared to connecting the fifth engagement / disengagement component 5 to the first drive shaft 101 and the second drive shaft 102 via a transmission device, by placing the fifth engagement / disengagement component 5 outside the second differential 104 and between the output gear 1044 and the planetary carrier 1043, the fifth engagement / disengagement component 5 can be directly connected to the first drive shaft 101 and the second drive shaft 102. This simplifies the connection structure between the fifth engagement / disengagement component 5 and the first drive shaft 101 and the second drive shaft 102, thereby facilitating the configuration of the fifth engagement / disengagement component 5 and improving the integration of the drive assembly 20.

[0159] Based on this, in some embodiments, such as Figure 5As shown, the drive assembly 20 also includes a sixth engagement / disengagement assembly 6, which is connected between the second drive shaft 102 and the second wheel 40.

[0160] The sixth engagement / disengagement assembly 6 has a fourth engagement state and a fourth disengagement state. When the sixth engagement / disengagement assembly 6 is in the fourth engagement state, the second drive shaft 102 is connected to the second wheel 40. When the sixth engagement / disengagement assembly 6 is in the fourth disengagement state, the second drive shaft 102 is disconnected from the second wheel 40.

[0161] In some embodiments, such as Figure 6 As shown, generator 9 is connected to the second drive shaft 102.

[0162] With the above settings, when the sixth engagement / disengagement component 6 is in the fourth engagement state, the generator 9 can transmit power to the second wheel 40 through the second drive shaft 102 and the sixth engagement / disengagement component 6, thereby driving the second wheel 40 to rotate, so as to realize the driving function of the generator 9.

[0163] When the sixth engagement / disengagement component 6 is in the fourth disconnection state, the engine 8 transmits power to the second drive shaft 102, which in turn transmits it to the generator 9, thereby enabling the generator 9 to generate electricity and realize its power generation function.

[0164] Specifically, when the first clutch 14 is engaged, the second clutch 15 is disengaged, the fifth engagement / disengagement assembly 5 is engaged, and the sixth engagement / disengagement assembly 6 is disengaged, the engine 8 operates, transmitting power sequentially through the first clutch 14, the second differential 104, and the first drive shaft 101 to the drive motor 111, causing the drive motor 111 to generate electricity. Power is also sequentially transmitted through the first clutch 14, the second differential 104, and the second drive shaft 102 to the generator 9, causing the generator 9 to generate electricity, thus putting the vehicle 100 into a parking power generation mode.

[0165] With the above settings, during the operation of the engine 8, power can be transmitted to the generator 9 and the drive motor 111 simultaneously, thereby driving the generator 9 and the drive motor 111 to generate electricity at the same time, so as to increase the rate at which the drive assembly 20 generates electrical energy and accelerate the charging rate of the vehicle 100.

[0166] In some other embodiments, when the first clutch 14 is disengaged, the second clutch 15 is engaged, the fifth engagement / disengagement assembly 5 is in a third disengaged state, and the sixth engagement / disengagement assembly 6 is in a fourth engaged state, the drive motor 111 operates, transmitting power to the first wheel 30 via the first drive shaft 101 to drive the first wheel 30 to rotate. The generator 9 operates, transmitting power to the second wheel 40 via the second drive shaft 102 to cause the second wheel 40 to rotate.

[0167] In this way, during the driving of the vehicle 100, the generator 9 can drive the second wheel 40 independently, and the drive motor 111 can drive the first wheel 30 independently, thereby meeting the power requirements of the first wheel 30 and the second wheel 40 under different conditions, improving the working performance of the drive assembly 20, and improving the applicability of the drive assembly 20.

[0168] In the above situations, in some examples, such as Figure 6 As shown, the drive assembly 20 also includes a first reducer 105, a second reducer 106, and a third reducer 107. The first reducer 105 is connected between the drive motor 111 and the first drive shaft 101. The second reducer 106 is connected between the generator 9 and the second drive shaft 102. The third reducer 107 is connected between the first clutch 14 and the second differential 104.

[0169] In other embodiments, such as Figure 1 As shown, Figure 6 for Figure 6 The schematic diagram of the drive assembly 20 including the seventh engagement / disengagement component 7 shows that the generator 9 is connected to the second differential 104 and to the first clutch 14.

[0170] With the above settings, when the sixth engagement / disengagement assembly 6 is in the fourth engagement state, the generator 9 can transmit power to the second wheel 40 through the second differential 104, the second drive shaft 102 and the sixth engagement / disengagement assembly 6, thereby driving the second wheel 40 to rotate, so as to realize the driving function of the generator 9.

[0171] Furthermore, during the operation of engine 8, engine 8 can transmit power to generator 9 through first clutch 14, so that generator 9 generates electricity and realizes the power generation function of generator 9.

[0172] Specifically, when the first clutch 14 is engaged, the second clutch 15 is disengaged, the fifth engagement / disengagement assembly 5 is engaged, and the sixth engagement / disengagement assembly 6 is disengaged, the engine 8 operates, transmitting power sequentially through the first clutch 14, the second differential 104, and the first drive shaft 101 to the drive motor 111, causing the drive motor 111 to generate electricity. Power is also transmitted through the first clutch 14 to the generator 9, causing the generator 9 to generate electricity, thus putting the vehicle 100 into a parking power generation mode.

[0173] With the above settings, during the operation of engine 8, engine 8 can also transmit power to generator 9 and drive motor 111 at the same time, thereby driving generator 9 and drive motor 111 to generate electricity at the same time, which can also increase the rate at which drive assembly 20 generates electrical energy and speed up the charging rate of vehicle 100.

[0174] In some embodiments, such as ​ As shown, the drive assembly 20 also includes a seventh engagement / disengagement assembly 7, which is connected between the second differential 104 and the generator 9.

[0175] The seventh engagement / disengagement assembly 7 has a fifth engaged state and a fifth disengaged state. When the seventh engagement / disengagement assembly 7 is in the fifth engaged state, the generator 9 is driven connected to the second differential 104. When the seventh engagement / disengagement assembly 7 is in the fifth disengaged state, the generator 9 is disconnected from the second differential 104.

[0176] With the above settings, when the first clutch 14 is in the disengaged state, the seventh engagement / disengagement component 7 is in the fifth engagement state, the fifth engagement / disengagement component 5 is in the third disengaged state, the sixth engagement / disengagement component 6 is in the fourth engagement state, and the second clutch 15 is in the engaged state, the generator 9 operates, transmitting power through the seventh engagement / disengagement component 7 and the second differential 104 to the first drive shaft 101 and the second drive shaft 102, thereby driving the first wheel 30 and the second wheel 40 to rotate. In this way, the generator 9 alone can simultaneously drive the first wheel 30 and the second wheel 40 to rotate, achieving smooth driving of the vehicle 100.

[0177] Alternatively, generator 9 operates, transmitting power sequentially to the second wheel 40 via the seventh engagement / disengagement assembly 7, the second differential 104, the second drive shaft 102, and the sixth engagement / disengagement assembly 6, thereby driving the second wheel 40 to rotate. Drive motor 111 operates, transmitting power to the first wheel 30 via the first drive shaft 101 and the second clutch 15, thereby driving the first wheel 30 to rotate. In this way, generator 9 and drive motor 111 can also independently drive the second wheel 40 and the first wheel 30 to rotate.

[0178] In the above situations, in some examples, such as​ As shown, the drive assembly 20 also includes a first reducer 105 and a third reducer 107. The first reducer 105 is connected between the drive motor 111 and the first drive shaft 101. The third reducer 107 is connected between the first clutch 14 and the second differential 104.

[0179] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
