DETAILED DESCRIPTION

[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0032] In the present disclosure, unless otherwise stated, the directional words used generally refer to the relevant parts under normal use. "Inside and outside" can refer to the inside and outside of the outline of the corresponding part or its location inside or outside the environment, depending on the specific context. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have order or importance.

[0033] like Figures 1 to 6 As shown, the present disclosure provides a hybrid drive system, including a planetary gear train 1, a first clutch 21, a brake 3, an engine 4 and a first motor 5, the planetary gear train 1 includes a first moving part 11, a second moving part 12 and a third moving part 13, wherein the brake 3 is used to brake or unlock the first moving part 11; the engine 4 and the first motor 5 are connected to the second moving part 12, and the third moving part 13 is used to output power; the first clutch 21 is used to engage or disconnect the first moving part 11 and the second moving part 12, or to engage or disconnect the first moving part 11 and the third moving part 13.

[0034] Through the above technical solution, the brake 3 can brake or unlock the first moving part 11, and the first clutch 21 can engage any two of the planetary gear trains, so that when the second moving part 12 receives the power transmitted by the engine 4 and the first motor 5, by adjusting the engagement or disconnection between the first moving part 11, the second moving part 12 and the third moving part 13, the power can be output from the third moving part 13 in two gears, so that the hybrid drive system disclosed in the present invention can realize multiple driving modes such as the two-gear output of the power of the engine 4, the two-gear output of the power of the first motor 5, and the two-gear output of the power of the engine 4 and the first motor 5 in parallel. When the hybrid drive system is applied to a vehicle, the vehicle can select different driving modes according to different driving scenes, ensuring the economy and power of the vehicle. And the hybrid drive system in the present application can realize multiple driving modes when using a planetary gear train 1, a brake 3 and a clutch, and the structure is more compact and occupies less space, which is simpler and easier to arrange.

[0035] Specifically, in the first gear, the brake 3 brakes the first moving member 11 and the first clutch 21 is disconnected. At this time, the first moving member 11 no longer rotates. When the second moving member 12 rotates, it will directly drive the third moving member 13 to rotate. At this time, the third moving member 13 can output power. Since there is a certain transmission ratio between the second moving member 12 and the third moving member 13, the power output by the third moving member 13 is different from the power transmitted to the second moving member 12. In the second gear, the brake 3 unlocks the first moving member 11 and the first clutch 21 is engaged. The first clutch 21 will engage the first moving member 11 and the second moving member 12 or the first moving member 11 and the third moving member 13. At this time, two of the three moving members will be combined into one through the first clutch 21. At this time, the entire planetary gear train 1 will operate as a whole. The three moving members have the same direction and the same speed. The transmission ratio between the second moving member 12 and the third moving member 13 is 1. At this time, the power output by the third moving member 13 is equal to the power transmitted to the second moving member 12.

[0036] At the same time, the second moving part 12 can receive the power transmitted by the engine 4 and the first motor 5. When only the engine 4 provides power, it can realize the two-speed output of the power of the engine 4. When only the first motor 5 provides power, it can realize the two-speed output of the power of the first motor 5. When the first motor 5 and the engine 4 provide power at the same time, it can realize the two-speed output of the parallel power of the engine 4 and the first motor 5. That is, in the case of two driving parts, the engine 4 and the first motor 5, the hybrid drive system of the present application can realize at least six driving modes.

[0037] The hybrid drive system may further include a second clutch 22, which is used to engage or disconnect the engine 4 and the second moving part 12. The second clutch 22 can make the power output by the engine 4 be more smoothly transmitted to the second moving part 12. For example, when the vehicle starts, the power can be output by the engine 4. At this time, the second clutch 22 can be gradually engaged from the disconnected state, and the torque transmitted by the second clutch 22 will gradually increase from zero, and the power will be smoothly transmitted to the second moving part 12, so that the vehicle starts smoothly. And when only the first motor 5 provides power, the second clutch 22 can disconnect the connection between the engine 4 and the second moving part 12, and the power transmitted by the first motor 5 to the second moving part 12 will not drive the engine 4 to idle, thereby ensuring the transmission efficiency.

[0038] In some embodiments, the hybrid drive system may include a transmission shaft 6, one end of which is transmission-connected to the second clutch 22, and the other end of which is transmission-connected to the output shaft of the first motor 5, wherein the transmission shaft 6 is fixedly connected to the second moving member 12, and the first moving member 11 and the third moving member 13 are respectively coaxially sleeved on the transmission shaft 6. In this way, the power of the engine 4 and the first motor 5 can be transmitted to the second moving member 12 through the transmission shaft 6, and the engine 4 and the first motor 5 can also drive the transmission shaft 6 at the same time. The engine 4 and the first motor 5 share a transmission structure, so that the hybrid drive system structure is more compact and occupies less space, which is simpler and easier to arrange. At the same time, in the planetary gear system 1, the first moving member 11, the second moving member 12 and the third moving member 13 are respectively coaxial, which is also more convenient for the arrangement of the transmission shaft 6, and the transmission shaft 6 can be directly passed through the planetary gear system 1.

[0039] Generally speaking, the speed range of the motor output shaft is greater than the speed range of the engine 4 output shaft, and the torque output by the motor is also greater than the torque output by the engine 4. When the engine 4 and the first motor 5 drive the second moving member 12 at the same time, in order to ensure that the torque output by the first motor 5 to the transmission shaft 6 is the same as the torque output by the engine 4 to the transmission shaft 6, the hybrid drive system may further include a first driving gear 71 and a first driven gear 72 that can mesh with each other, the first driving gear 71 may be connected to the output shaft of the first motor 5, and the first driven gear 72 may be connected to the transmission shaft 6, wherein the transmission ratio between the first driving gear 71 and the first driven gear 72 is greater than the transmission ratio between the engine 4 and the transmission shaft 6. When the transmission ratio between the first driving gear 71 and the first driven gear 72 is appropriate, the torque output by the first motor 5 to the transmission shaft 6 is the same as the torque output by the engine 4 to the transmission shaft 6, thereby ensuring the stability of the transmission shaft 6. If the torque outputted from the first motor 5 to the transmission shaft 6 is different from the torque outputted from the engine 4 to the transmission shaft 6 when the engine 4 and the first motor 5 drive the second moving member 12 simultaneously, the transmission shaft 6 will be subjected to torsional stress, resulting in bending and deformation of the transmission shaft 6, affecting the strength and stability of the transmission shaft 6. It will also cause torsional vibration of the transmission shaft 6, increase noise, and affect the smooth operation and service life of the hybrid drive system.

[0040] In addition, in other embodiments, the hybrid drive system may further include a second driving gear 73 and a second driven gear 74 that can mesh with each other, the second driving gear 73 is connected to the output shaft of the engine 4, and the second driven gear 74 is connected to the transmission shaft 6, wherein the transmission ratio between the second driving gear 73 and the second driven gear 74 is smaller than the transmission ratio between the first motor 5 and the transmission shaft 6. In this way, the engine 4 can be indirectly connected to the transmission shaft 6, the second driving gear 73 can be connected to the output shaft of the engine 4, and the second driven gear 74 can be connected to the transmission shaft 6, and at this time, the transmission ratio between the second driving gear 73 and the second driven gear 74 can be smaller than the transmission ratio between the first motor 5 and the transmission shaft 6. Since the torque output by the first motor 5 is greater than the torque output by the engine 4, when the transmission ratio between the second driving gear 73 and the second driven gear 74 is smaller than the transmission ratio between the first motor 5 and the transmission shaft 6, the torque output by the engine 4 to the transmission shaft 6 will be greater than the torque output by the engine 4 itself. When the transmission ratio between the second driving gear 73 and the second driven gear 74 is appropriate, the torque output by the engine 4 to the transmission shaft 6 will be the same as the torque output by the first motor 5 to the transmission shaft 6, thereby ensuring the stability of the transmission shaft 6.

[0041] In the planetary gear train 1, the movable parts include a sun gear, a ring gear, a plurality of planetary gears and a planet carrier. The planet carrier is connected to the plurality of planetary gears at the same time. The planet carrier and the planetary gears need to be connected to each other to rotate simultaneously. Therefore, the planetary gear train 1 can be generally understood as having three moving parts, namely, a sun gear, a ring gear and a planet carrier. The first moving part 11 can be any one of the sun gear, the ring gear and the planet carrier, the second moving part 12 can be any one of the two except the first moving part 11, and the third moving part 13 can be the last one.

[0042] exist Figures 1 to 6 In the six embodiments shown, the first moving part 11 is a sun gear, the second moving part 12 is a ring gear, and the third moving part 13 is a planet carrier, wherein in the first embodiment, the second embodiment, and the third embodiment, the first clutch 21 is connected between the planet carrier and the sun gear, and the first clutch 21 is used to engage or disconnect the first moving part 11 and the third moving part 13. In the fourth embodiment, the fifth embodiment, and the sixth embodiment, the first clutch 21 is connected between the ring gear and the sun gear, and the first clutch 21 is used to engage or disconnect the first moving part 11 and the second moving part 12.

[0043] In the first gear, Figures 1 to 6 In the six embodiments shown, the brake 3 brakes the sun gear and the first clutch 21 is disconnected. At this time, the sun gear no longer rotates. When the ring gear rotates, it will directly drive the planet carrier to rotate, and the planet carrier outputs power. When the sum of the number of teeth of the multiple planetary gears connected to the planet carrier is greater than the number of teeth of the ring gear, the transmission ratio of the ring gear to the planet carrier is greater than 1. At this time, the planet carrier rotates at a reduced speed compared to the ring gear, and the power output from the planet carrier is less than the power input to the ring gear. Conversely, when the sum of the number of teeth of the multiple planetary gears connected to the planet carrier is less than the number of teeth of the ring gear, the transmission ratio of the ring gear to the planet carrier is less than 1. At this time, the planet carrier rotates at a faster speed compared to the ring gear, and the power output from the planet carrier is greater than the power input to the ring gear.

[0044] In the second gear, the brake 3 unlocks the sun gear and the first clutch 21 is engaged. In the first, second and third embodiments, the sun gear and the planet carrier are combined into one via the first clutch 21. In the fourth, fifth and sixth embodiments, the ring gear and the planet carrier are combined into one via the first clutch 21. At this time, the entire planetary gear train 1 operates as a whole, the sun gear, the planet carrier and the ring gear have the same direction and the same speed, the transmission ratio between the ring gear and the planet carrier is 1, and the power output from the planet carrier is equal to the power transmitted to the ring gear.

[0045] In the present application, in addition to the above six embodiments, the selection of the first moving part 11, the second moving part 12 and the third moving part 13 can also have multiple embodiments. For example: the first moving part 11 is a ring gear, the second moving part 12 is a sun gear, and the third moving part 13 is a planet carrier. In this way, the first gear can be determined to be an increase in speed or a decrease in speed compared to the second gear by adjusting the relationship between the number of teeth of the multiple planetary wheels connected to the planet carrier and the number of teeth of the sun gear. For another example, the first moving part 11 is a sun gear, the second moving part 12 is a planet carrier, and the third moving part 13 is a ring gear. In this way, the first gear can be determined to be an increase in speed or a decrease in speed compared to the second gear by adjusting the relationship between the number of teeth of the multiple planetary wheels connected to the planet carrier and the number of teeth of the ring gear. In the present application, the selection of the first moving part 11, the second moving part 12 and the third moving part 13 is not specifically limited, and can be adaptively selected according to the actual working scene and the structure of the planetary gear system 1.

[0046] At the same time, the hybrid drive system can also include a second motor 8 connected to the engine 4, and the second motor 8 can be driven by the engine 4 to generate electricity. In this way, when the engine 4 drives the second moving part 12, it can also drive the second motor 8 to generate electricity at the same time. When the engine 4 does not drive the second moving part 12, the engine 4 can also drive the second motor 8 alone to generate electricity. The electric energy generated by the second motor 8 can be further used by other devices to achieve energy recovery and optimize energy utilization. When the engine 4 drives the second motor 8 alone to generate electricity, in order to avoid interference with the transmission shaft 6, the second clutch 22 can be disconnected at this time.

[0047] Reference Figure 1 and Figure 4 In the first and fourth embodiments, the power shaft of the second motor 8 can be coaxially sleeved on the output shaft of the engine 4. This reduces the transmission structure between the second motor 8 and the engine 4, correspondingly reduces the maintenance difficulty and the risk of component wear, and improves the reliability of the connection.

[0048] Reference Figure 2 and Figure 5 In the second and fifth embodiments, the hybrid drive system may further include a third driving gear 75 and a third driven gear 76 that can mesh with each other, the third driving gear 75 is connected to the output shaft of the engine 4, and the third driven gear 76 is connected to the power shaft of the second motor 8. In this way, the speed of the second motor 8 can be flexibly adjusted through the third driving gear 75 and the third driven gear 76 to adapt to the speed range required for the best power generation efficiency without being completely limited to the output speed of the engine 4, thereby improving the power generation efficiency and stability. Further reference Figure 3 and Figure 6In the third and sixth embodiments, the second driving gear 73 and the third driving gear 75 may be the same gear, thereby reducing the structure required for the hybrid drive system.

[0049] exist Figures 1 to 6 In the six embodiments shown, the second motor 8 is directly connected to the engine 4. In addition, in other embodiments, the second motor 8 and the engine 4 may be indirectly connected. For example, the hybrid drive system may further include a third clutch, and the second motor 8 may be indirectly connected to the engine 4 through the third clutch. In this way, the second motor 8 and the engine 4 can be combined through the third clutch. When the second motor 8 does not need to generate electricity and the engine 4 needs to drive the second moving part 12, the engine 4 will not drive the second motor 8 additionally, thereby avoiding the loss of the output power of the engine 4.

[0050] In order to protect the planetary gear train 1, the first clutch 21, the brake 3, the engine 4 and the first motor 5, the hybrid drive system further includes a housing, in which the planetary gear train 1, the first clutch 21, the brake 3, the engine 4 and the first motor 5 are respectively accommodated, wherein one end of the brake 3 is fixedly connected to the housing, and the other end is selectively connected to the first moving part 11. In this way, the inner wall of the housing can also play a role in fixing the brake 3.

[0051] According to the second aspect of the present disclosure, a vehicle is also provided, comprising wheels, a differential 9 and a hybrid drive system of any one of the above-mentioned embodiments, and having all the beneficial effects thereof, which will not be repeated here, wherein the wheels are connected to the differential 9, and the third moving part 13 is connected to the input shaft of the differential 9.

[0052] The extension direction of the output shaft of the engine 4 can be perpendicular to the extension direction of the vehicle half-axle of the vehicle. In this case, the engine 4 is a longitudinally mounted engine 4, which has high transmission efficiency and low power loss, and can therefore provide more efficient power output. At the same time, the longitudinal arrangement of the engine 4 can also release more lateral space for installing more advanced suspension systems, such as multi-link or double wishbone suspensions, which have better performance in terms of comfort.

[0053] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0055] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
