[0033] Combined with Figures 1 to 2 As shown, according to a specific embodiment of the present application, a multi-gear hybrid power device is provided.

[0034] Specifically, a multi-gear hybrid power device includes: a motor EM110; a first planetary gear set 20, one end of the first planetary gear set 20 is connected to the motor EM110, and the other end of the first planetary gear set 20 is respectively connected to a first clutch 40, a second clutch 41, a first brake 42 and a second brake 43; a second planetary gear set 30, one end of the second planetary gear set 30 is connected to the motor EM110; an engine 91, the engine is arranged adjacent to the second planetary gear set 30, and the engine 91 is connected to the other end of the second planetary gear set 30; wherein, the motor EM110 is arranged between the first planetary gear set 20 and the second planetary gear set 30. When the second clutch 41 is connected to the first brake 42, the multi-gear hybrid power device is in the EV1 gear. When the first clutch 40 is connected to the second clutch 41, the multi-gear hybrid power device is in the EV2 gear. When the first clutch 40 is connected to the first brake 42, the multi-gear hybrid power device is in the EV3 gear. When the first clutch 40 is connected to the second brake 43, the multi-gear hybrid power device is in the EV4 gear.

[0035] In this embodiment, the first end of the first planetary gear set is connected to the motor EM1, the second end of the first planetary gear set is connected to the first clutch, the second clutch, the first brake and the second brake, and the first end of the second planetary gear set is connected to the motor EM1, so that the vehicle can achieve multiple EV working modes with only one motor and engine for driving. At the same time, through the Ravigneaux planetary gear set layout, the output end is connected to multiple clutches and selectively outputs, and at least 4 driving gears can be achieved.

[0036] Further, the first planetary gear set 20 includes: a first outer gear ring 21, one end of the first outer gear ring 21 is connected to the motor EM110; a first long planetary gear 22, the first long planetary gear meshes with the first outer gear ring 21; a first planetary carrier 23, the first long planetary gear 22 is sleeved on the first planetary carrier 23, the first end of the first planetary carrier 23 is connected to the second brake 43, and the second end of the first planetary carrier 23 is connected to the first clutch 40; a first long sun gear 24, the first end of the first long sun gear 24 meshes with the first long planetary gear 22, the second end of the first long sun gear 24 is connected to the first brake 42, and the first long planetary gear 22 is respectively connected to the first clutch 40 and the second clutch 41. Such a setting makes the first planetary gear set 20 stably connected to the motor EM110, and makes the motor EM110 connected to the first clutch 40 and the second clutch 41 through the first planetary gear set 20. It ensures the stability of the power transmission of the multi-gear hybrid power device.

[0037] Further, the first planetary gear set 20 further includes: a first short planetary gear 25, the axis of the first short planetary gear 25 being parallel to the axis of the first long planetary gear 22, one end of the first short planetary gear 25 being meshed and connected with the first long planetary gear 22, and the first short planetary gear 25 being connected to the first clutch 40; a first short sun gear 26, one end of the first short sun gear 26 being meshed and connected with the other end of the first short planetary gear 25, and the other end of the first short sun gear 26 being connected to the second clutch 41. Such a setting enables the power to be communicated through the first short sun gear 26, the first short planetary gear 25, and the second clutch 41, ensuring the stability of the power transmission of the multi-gear hybrid power device.

[0038] Further, the multi-gear hybrid power device further includes: a first intermediate shaft 50, the first end of the first intermediate shaft 50 being connected to the first planet carrier 23, and the second end of the first intermediate shaft 50 being connected to the second end of the second clutch 41; a second intermediate shaft 51, the first end of the second intermediate shaft 51 being connected to the first short sun gear 26, and the second end of the second intermediate shaft 51 being connected to the first end of the first clutch 40; a third intermediate shaft 52, the first end of the third intermediate shaft 52 being connected to the second end of the first long sun gear 24, and the second end of the third intermediate shaft 52 being connected to the first brake 42; wherein, the axes of the first intermediate shaft 50, the second intermediate shaft 51, and the third intermediate shaft 52 are arranged in parallel. Such a setting enables the first planetary gear set 20 to be connected to the first clutch 40, the second clutch 41, and the first brake 42 through the first intermediate shaft 50, the second intermediate shaft 51, and the third intermediate shaft 52, effectively increasing the number of gears and the braking capacity of the multi-gear hybrid power device.

[0039] In another embodiment of the present application, one end of the output shaft 60 is respectively connected to the first clutch 40 and the second clutch 41, and the other end of the output shaft 60 is connected to the wheel 70. Such a setting enables the multi-gear hybrid power device to stably transmit the power to the wheel 70.

[0040] Further, the second planetary gear set 30 includes: a second sun gear 31, one end of the second sun gear 31 is connected to one end of the one-way clutch 80, wherein the other end of the one-way clutch 80 is connected to the motor EM110; a second planetary gear 32, the axis of the second planetary gear 32 is parallel to the axis of the first long planetary gear 22, and one end of the second planetary gear 32 meshes with the second sun gear 31; a second outer gear ring 33, one end of the second outer gear ring 33 meshes with the second planetary gear 32, and the other end of the second outer gear ring 33 is fixedly connected to the vehicle body; a second planetary carrier 34, the second planetary gear 32 is sleeved on the second planetary carrier 34, and the second planetary carrier 34 is connected to the first end of the input shaft 90, and the second end of the input shaft 90 is connected to the engine 91 through a coupler. Such an arrangement effectively enables the power to pass through the second sun gear 31, through the one-way clutch 80, and be transmitted to the motor EM1, forming a parallel mode. The function of the one-way clutch 80 is to enable the engine output power to be output to the motor EM1, and also to prevent the motor power from being output in the direction of the engine, that is, it can prevent the engine from being reverse-dragged, avoid power loss, and also improve the engine life.

[0041] Further, when the multi-gear hybrid power device is in the EV1 gear position, the first brake 42 is braked, and the output shaft 60 is driven to rotate through the second clutch 41; when the multi-gear hybrid power device is in the EV2 gear position, the motor EM110 drives the first intermediate shaft 50 and the second intermediate shaft 51 to rotate, and the first intermediate shaft 50 and the second intermediate shaft 51 drive the output shaft 60 to rotate through the first clutch 40 and the second clutch 41. Such an arrangement enables the multi-gear hybrid power device to have the EV1 gear position and the EV2 gear position, ensuring the diversity of the gear positions of the multi-gear hybrid power device.

[0042] Specifically, when the multi-gear hybrid power device is in the EV3 gear position, the first brake 42 is braked, and the output shaft 60 is driven to rotate through the first clutch 40; when the multi-gear hybrid power device is in the EV4 gear position, the second brake 43 is braked, and the output shaft 60 is driven to rotate through the first clutch 40. Such an arrangement enables the multi-gear hybrid power device to have the EV3 gear position and the EV4 gear position, ensuring the diversity of the gear positions of the multi-gear hybrid power device.

[0043] Furthermore, the multi-gear hybrid power device also has a parallel mode and a parking power generation mode. When the multi-gear hybrid power device is in the parallel mode or the parking power generation mode, the second sun gear 31 transmits power to the motor EM110 through the one-way clutch 80. Such a setting enables the multi-gear hybrid power device to achieve multi-mode operating conditions such as the EV mode, the parallel mode, the parallel mode, and the parking power generation mode with only one motor and the engine for driving. At the same time, through the Ravigneaux planetary gearset layout, the output end is connected to multiple clutches and selectively outputs, enabling at least 4 driving gears. During rapid acceleration, the engine intervenes in a timely manner and can also provide quite effective assistance to avoid the driving motor operating away from the high-efficiency range.

[0044] In another embodiment of the present application, in the EV1 gear:

[0045] The second clutch is engaged and the first brake is engaged. The power of the motor is transmitted through the motor rotor to the first external gear ring connected thereto, driving the first external gear ring to rotate. Since the first brake is braked, the third intermediate shaft connected thereto cannot rotate. Further, the first long sun gear is restricted from rotating, so that the rotation state of the first planetary gear set is unique, that is, the first external gear ring drives the first long planetary gear meshing therewith. Since the first long sun gear is braked, the first planetary carrier is driven to rotate. The power is output from the uniquely rotating first planetary carrier to the first intermediate shaft, and through the engaged second clutch, it is transmitted to the output shaft, thereby driving the wheels.

[0046] In the EV2 gear:

[0047] The first clutch and the second clutch are engaged. The power of the motor is transmitted through the motor rotor to the first external gear ring connected thereto, driving the first external gear ring to rotate. Since the first clutch and the second clutch are engaged, one side of the first clutch and the second clutch are respectively connected to the second intermediate shaft and the first intermediate shaft, and the other side of both is connected to the same output member, the output shaft. Therefore, the second intermediate shaft and the first intermediate shaft rotate at the same speed. Further, the first short sun gear and the first planetary carrier connected to the second intermediate shaft and the first intermediate shaft rotate at the same speed. Furthermore, the entire first planetary gear set rotates at the same speed as the first external gear ring. Therefore, the rotational speed of the output shaft is the same as that of the first external gear ring, thereby driving the wheels.

[0048] In the EV3 gear:

[0049] The first clutch is engaged and the first brake is engaged. The power of the motor is transmitted through the motor rotor to the first external gear ring connected thereto, driving the first external gear ring to rotate. Since the first brake is braked, the third intermediate shaft connected thereto cannot rotate. Further, the first long sun gear is restricted from rotating, so that the rotation state of the first planetary gear set is unique. That is, the first external gear ring drives the first long planetary gear meshing therewith. Since the first long sun gear is braked, the first planetary carrier is driven to rotate. The first short planetary gear is driven simultaneously by the first planetary carrier and the first long planetary gear, thus driving the first short sun gear meshing therewith to rotate. The power is transmitted to the second intermediate shaft through the first short sun gear with a unique rotation state, and then through the engaged first clutch to the output shaft, thereby driving the wheels.

[0050] In the EV4 gear position:

[0051] The first clutch is engaged and the second brake is engaged. The power of the motor is transmitted through the motor rotor to the first external gear ring connected thereto, driving the first external gear ring to rotate. Since the second brake is engaged, the first planetary carrier connected thereto is fixed. The first external gear ring drives the first long planetary gear to rotate self - rotatively. The first long planetary gear drives the first short planetary gear to rotate self - rotatively, thus driving the first short sun gear to rotate. The power is transmitted to the second intermediate shaft through the first short sun gear, and further through the engaged first clutch to the output shaft, thereby driving the wheels.

[0052] Parallel mode:

[0053] In the EV1 to EV4 gear positions, the engine can be started as required to form a parallel mode. At this time, the power of the engine is transmitted through the coupler to the input shaft to drive the second planetary carrier to revolve. The second external gear ring is fixedly connected to the housing, thus driving the second planetary gear to revolve and rotate self - rotatively, and further driving the second sun gear to rotate. And according to the characteristics of the planetary gear set, a speed - increasing ratio is formed, that is, the speed of the second sun gear is higher than the speed of the second planetary gear set, that is, higher than the engine speed. This configuration is more suitable for the engine to match a high - speed motor at low engine speeds. The power is transmitted to the motor EM1 through the second sun gear and the one - way clutch, forming a parallel mode. The function of the one - way clutch is to enable the engine output power to be output to the motor, and also to prevent the motor power from being output in the direction of the engine, that is, to avoid reverse - dragging the engine, avoid power loss, and also improve the service life of the engine.

[0054] Parking power generation mode:

[0055] The vehicle is in a parked state, and the engine is started. At this time, the engine power is transmitted through the coupler to the input shaft to drive the second planet carrier to revolve. The second outer gear ring is fixedly connected to the housing, thereby driving the second planet gear to revolve and rotate, further driving the second sun gear to rotate, and according to the characteristics of the planetary gear train, a speed ratio is formed. The power passes through the one-way clutch via the second sun gear and is transmitted to the motor EM1 to form a power generation mode.

[0056] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0057] 1. With only one motor and engine drive, it is possible to achieve multi-mode working conditions such as EV mode, parallel mode, energy recovery, and parking power generation mode. At the same time, through the Ravigneaux planetary gear train layout, the output end is connected to multiple clutches for selective output, and at least 4 driving gears can be achieved. During rapid acceleration, the engine intervenes in a timely manner, which can also provide quite effective assistance and prevent the drive motor from operating away from the high-efficiency range.

[0058] 2. The planetary gear train structure is arranged coaxially, and the utilization rate of space and configuration is optimized to the extreme.

[0059] 3. A simple planetary gear train and a one-way clutch are arranged between the motor and the engine. Its advantages are that, on the one hand, through the principle of the planetary gear train, the engine speed is amplified to match the motor speed; on the other hand, the existence of the one-way clutch can effectively prevent the motor from reverse-dragging the engine crankshaft and causing energy loss in the case of insufficient engine speed or when the engine is not started.

[0060] For ease of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" etc. may be used here to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation shown in the figures of the device.

Thus, the exemplary term "above..." can include both orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.
