[0071] The third ring gear 44 of the Ravina planetary gear set is connected to the first drive shaft 63 via a spline connection.

By constructing the transmission device 4 as a Ravina planetary gear set, the vehicle's power performance can be improved, the driving experience enhanced, and the layout of the drive assembly 10 reduced.

[0072] In some embodiments of this utility model, such as Figure 1 As shown, the third sun gear 41 of the Ravina planetary gear set meshes with the first planet gear 45 of the Ravina planetary gear set, the fourth sun gear 42 of the Ravina planetary gear set meshes with the second planet gear 46 of the Ravina planetary gear set, and the first planet gear 45 meshes between the second planet gear 46 and the third gear ring 44; the first gear ring 23 selectively engages with the third sun gear 41, the first gear ring 23 selectively engages with the fourth sun gear 42, the first gear ring 23 selectively engages with the third planet carrier 43 of the Ravina planetary gear set, the third sun gear 41 selectively locks, and the third planet carrier 43 selectively locks.

[0073] The Ravina planetary gear set includes a third sun gear 41, a fourth sun gear 42, a first planet gear 45, a second planet gear 46, and a third ring gear 44. The third sun gear 41 meshes with the first planet gear 45, and the fourth sun gear 42 meshes with the second planet gear 46. The first planet gear 45 meshes between the second planet gear 46 and the third ring gear 44; that is, the first planet gear 45 meshes with the second planet gear 46, and the first planet gear 45 meshes with the third ring gear 44.

[0074] The first gear ring 23 selectively engages with the third sun gear 41, meaning that the first gear ring 23 may engage with the third sun gear 41, or it may not engage with the third sun gear 41. The first gear ring 23 selectively engages with the fourth sun gear 42, meaning that the first gear ring 23 may engage with the fourth sun gear 42, or it may not engage with the fourth sun gear 42.

[0075] The first gear ring 23 selectively engages with the third planet carrier 43 of the Ravina planetary array; that is, the first gear ring 23 may engage with the third planet carrier 43, or the first gear ring 23 may not engage with the third planet carrier 43. The third sun gear 41 is selectively locked; that is, the third sun gear 41 may be locked, or the third sun gear 41 may not be locked. The third planet carrier 43 is selectively locked; that is, the third planet carrier 43 may be locked, or the third planet carrier 43 may not be locked.

[0076] The drive assembly 10 of this application can have multiple gears by controlling the Ravina planetary gear set. The Ravina planetary gear set can transmit power to the first output shaft 61 through the third ring gear 44 in different gears according to the actual working conditions. The specific working states of the Ravina planetary gear set under multiple gears are described in detail below.

[0077] In the first gear position, the first ring gear 23 is engaged with the fourth sun gear 42, the first ring gear 23 is disengaged from the third sun gear 41, the first ring gear 23 is disengaged from the third planet carrier 43, the third sun gear 41 is not locked, the third planet carrier 43 is locked, and the power of the first ring gear 23 can be transmitted through the fourth sun gear 42 to the second planet gear 46, then through the second planet gear 46 to the first planet gear 45, then through the first planet gear 45 to the third ring gear 44, and finally to the first output shaft 61.

[0078] In the second gear position, the first ring gear 23 engages with the fourth sun gear 42, the first ring gear 23 disengages from the third sun gear 41, the first ring gear 23 disengages from the third planet carrier 43, the third sun gear 41 is locked, and the third planet carrier 43 is not locked. The power of the first ring gear 23 can be transmitted through the fourth sun gear 42 to the second planet gear 46, then through the second planet gear 46 to the first planet gear 45, then through the first planet gear 45 to the third ring gear 44, and finally to the first output shaft 61.

[0079] In the third gear position, the first ring gear 23 engages with the fourth sun gear 42, the first ring gear 23 disengages from the third sun gear 41, and the first ring gear 23 engages with the third planet carrier 43. The third sun gear 41 is not locked, and the third planet carrier 43 is not locked. At this time, the Ravina planetary gear set is equivalent to a whole, and the power of the first ring gear 23 can be transmitted to the first output shaft 61 through the Ravina planetary gear set as a whole.

[0080] In the fourth gear position, the first ring gear 23 is disengaged from the fourth sun gear 42, the first ring gear 23 is disengaged from the third sun gear 41, the first ring gear 23 is engaged with the third planet carrier 43, the third sun gear 41 is locked, the third planet carrier 43 is not locked, and the power of the first ring gear 23 can be transmitted to the third ring gear 44 through the third planet carrier 43, and then to the first output shaft 61.

[0081] In reverse gear, the first ring gear 23 is disengaged from the fourth sun gear 42, the first ring gear 23 is engaged with the third sun gear 41, the first ring gear 23 is disengaged from the third planet carrier 43, the third sun gear 41 is not locked, the third planet carrier 43 is locked, and the power of the first ring gear 23 can be transmitted to the first planet gear 45 through the third sun gear 41, then to the third ring gear 44 through the first planet gear 45, and finally to the first output shaft 61.

[0082] Understandably, by controlling the Ravina planetary gear set, each operating mode can have multiple gears. For example, the first engine 11 direct drive mode can have four forward gears, and the second engine 11 direct drive mode can have four forward gears.

[0083] It should be noted that the gears described above can all be applied to modes that require power transmission through the Ravina planetary gear set. By controlling the Ravina planetary gear set, the power output from the first ring gear 23 to the first output shaft 61 can vary, allowing the vehicle to shift gears according to different operating conditions and provide sufficient power to the vehicle stably over a long period. It is understood that the power of the second motor 13 is not transmitted to the first output shaft 61 through the Ravina planetary gear set, and the second motor 13 has independent forward and reverse gears. This configuration allows the drive assembly 10 to have multiple gears, enabling the vehicle to shift gears according to different operating conditions and provide sufficient power to the vehicle stably over a long period, thus improving the vehicle's power performance.

[0084] In some embodiments of this utility model, such as Figure 1 As shown, the drive assembly 10 also includes a second coupling 72, which is connected to the first drive shaft 63. The second coupling 72 can be selectively coupled to or not coupled to any one of the second sun gear 31 and the second planet carrier 32.

[0086] The second coupling device 72 may selectively engage with either the second sun gear 31 or the second planet carrier 32, or not engage with either of them. That is, the second coupling device 72 may engage with the second sun gear 31, or the second coupling device 72 may engage with the second planet carrier 32, or the second coupling device 72 may not engage with either the second sun gear 31 or the second planet carrier 32.

[0087] As some embodiments of this application, the second sun gear 31 may have a second coupling portion 311, which is disposed facing the second coupling member 72.

The second planetary carrier 32 may have a third coupling portion 321, which is disposed facing the second coupling member 72. The second coupling member 72 can engage the first drive shaft 63 with the third coupling portion 321 to enable a transmission connection between the first drive shaft 63 and the second planetary carrier 32.

[0088] This configuration allows the first drive shaft 63 to selectively engage with either the second sun gear 31 or the second planetary carrier 32 via the second coupling 72, or to disengage the first drive shaft 63 from either the second sun gear 31 or the second planetary carrier 32. Furthermore, it enables the switching process to be rapid and reliable, facilitating flexible switching of drive modes in the drive assembly 10.
