The first ring gear 23 is connected to the output shaft 1 through a transmission device. The second ring gear 33 is locked.

[0060] It should be noted that the descriptions of the various working modes described above are merely illustrative and do not imply that the driver assembly 100 proposed in this application is limited to the above working modes, nor do they imply that the driver assembly 100 proposed in this application is limited by the above working modes.

[0061] Therefore, the drive assembly 100 of this application, through the combination of the first planetary gear set 20, the second planetary gear set 30 and the transmission device, can have multiple working modes and gears, and can stably provide sufficient power to the vehicle for a long time, which is conducive to improving the vehicle's power performance and improving the driving experience.

[0062] Furthermore, the drive assembly 100 of this application has the ability to continuously provide high torque and high power output to the vehicle. Under complex conditions such as high-speed overtaking and long-term uphill climbing, it can continuously provide high torque and high output, greatly improving driving performance and experience, and can be widely used in passenger vehicles.

[0063] Furthermore, the drive assembly 100 of this application can achieve long-term, high-power, and high-torque input and output, and can compensate for torque when the drive assembly 100 switches working modes or gears, which can reduce or even eliminate the risk of power interruption and improve the vehicle's power performance.

[0064] As some embodiments of this application, the output shaft 1 can be connected to a differential drive, and the differential can be connected to the wheel ends of the vehicle drive.

[0066] The third gear ring 44 is connected to the output shaft 1 via a transmission connection. The transmission connection between the third gear ring 44 and the output shaft 1 can be, but is not limited to, spline connection, gear pair connection, etc. As some embodiments of this application, the third gear ring 44 and the output shaft 1 are connected via a spline connection.

[0067] This configuration improves the reliability of the connection between the Ravina planetary gear set 40 and the output shaft 1. Furthermore, by adjusting the engagement relationship between the Ravina planetary gear set 40 and the first planetary gear set 20, the gears can be switched, allowing the various modes of the drive assembly 100 proposed in this application to have multiple gears. This provides sufficient power to the vehicle stably for a long time, which is beneficial for improving the vehicle's power performance and enhancing the driving experience.

[0068] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the front sun gear 41 of the Ravina planetary gear set 40 meshes with the first planet gear 45 of the Ravina planetary gear set 40, the rear sun gear 42 of the Ravina planetary gear set 40 meshes with the second planet gear 46 of the Ravina planetary gear set 40, the second planet gear 46 meshes with the first planet gear 45, the first planet gear 45 meshes with the third ring gear 44, the first ring gear 23 selectively engages with the front sun gear 41, the first ring gear 23 selectively engages with the rear sun gear 42, the first ring gear 23 selectively engages with the third planet carrier 43 of the Ravina planetary gear set 40, the front sun gear 41 is selectively locked, and the third planet carrier 43 is selectively locked.

[0069] Among them, the Ravina planetary gear 40 includes a front sun gear 41, a rear sun gear 42, a first planet gear 45, a second planet gear 46, and a third gear ring 44. The front sun gear 41 meshes with the first planet gear 45, the first planet gear 45 meshes with the second planet gear 46, the rear sun gear 42 meshes with the second planet gear 46, and the first planet gear 45 meshes with the third gear ring 44.

[0070] The first ring gear 23 selectively engages with the front sun gear 41, meaning that the first ring gear 23 may engage with the front sun gear 41 or may not engage with the front sun gear 41. The first ring gear 23 selectively engages with the rear sun gear 42, meaning that the first ring gear 23 may engage with the rear sun gear 42 or may not engage with the rear sun gear 42.

[0071] The first gear ring 23 selectively engages with the third planet carrier 43 of the Ravina planetary array 40; 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 front sun gear 41 is selectively locked; that is, the front sun gear 41 may be locked, or the front 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.

[0072] The drive assembly 100 of this application can have multiple gears by controlling the Ravina planetary gear set 40. The Ravina planetary gear set 40 can transmit power to the output shaft 1 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 40 under multiple gears are described in detail below using the first embodiment of this application as an example.

[0073] In first gear, the first ring gear 23 engages with the rear sun gear 42, disengages from the front sun gear 41, and disengages from the third planet carrier 43. The front sun gear 41 is not locked, and the third planet carrier 43 is locked. The power of the first ring gear 23 can be transmitted through the rear 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 output shaft 1.

[0074] In second gear, the first ring gear 23 engages with the rear sun gear 42, disengages from the front sun gear 41, and disengages from the third planet carrier 43. The front sun gear 41 is locked, and the third planet carrier 43 is unlocked. The power of the first ring gear 23 can be transmitted through the rear 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 output shaft 1.

[0075] In third gear, the first ring gear 23 engages with the rear sun gear 42, the first ring gear 23 disengages from the front sun gear 41, and the first ring gear 23 engages with the third planetary carrier 43. The front sun gear 41 is not locked, and the third planetary carrier 43 is not locked. At this time, the Ravina planetary gear set 40 is equivalent to a whole unit, and the power of the first ring gear 23 can be transmitted to the output shaft 1 through the Ravina planetary gear set 40 as a whole unit.

[0076] In fourth gear, the first ring gear 23 is disengaged from the rear sun gear 42 and the front sun gear 41. The first ring gear 23 is engaged with the third planetary carrier 43, the front sun gear 41 is locked, and the third planetary carrier 43 is not locked. The power of the first ring gear 23 can be transmitted to the third ring gear 44 through the third planetary carrier 43, and finally to the output shaft 1.

[0077] In reverse gear, the first ring gear 23 is disengaged from the rear sun gear 42, the first ring gear 23 is engaged with the front sun gear 41, the first ring gear 23 is disengaged from the third planet carrier 43, the front 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 front sun gear 41, then to the third ring gear 44 through the first planet gear 45, and finally to the output shaft 1.

[0078] 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 40. By controlling the Ravina planetary gear set 40, the power output from the first ring gear 23 to the output shaft 1 can be varied, allowing the vehicle to change gears according to different operating conditions, thus providing sufficient power to the vehicle stably over a long period. It is understood that the power of the second motor 12 is not transmitted to the output shaft 1 through the Ravina planetary gear set 40, and the second motor 12 has independent forward and reverse gears.

[0079] This configuration allows the drive assembly 100 to have multiple gears, enabling the vehicle to change gears according to different operating conditions, thus providing sufficient power to the vehicle stably over a long period of time and improving the vehicle's power performance.
