Among them, the bold solid line is the path of power transmission, and the specific control method is as follows:
在第一离合器31结合、第二离合器32断开以及第一制动器41和第二制动器42同时断开的情况下，开启发动机60和电机70，发动机60的动力由第一外齿圈13传递至第一行星架11，电机70的动力由第一太阳轮14传递至第一行星架11，第一行星架11驱动输出轴51转动，实现无级变速挡位传动。When the first clutch 31 is combined, the second clutch 32 is disconnected, and the first brake 41 and the second brake 42 are disconnected simultaneously, the engine 60 and the motor 70 are turned on, and the power of the engine 60 is transmitted from the first outer ring gear 13 to The first planet carrier 11, the power of the motor 70 is transmitted to the first planet carrier 11 by the first sun gear 14, and the first planet carrier 11 drives the output shaft 51 to rotate to realize the continuously variable gear transmission.
需要说明的是，无级变速传动(ECVT)工况下，在改变转速时，需要保持发动机60和电机70中的一个动力恒定，即发动机60的转速不变的情况下来提升电机70的转速和电机70的转速不变的情况下来提升发动机60的转速，最终实现两者动力进行耦合。具体地，第一离合器31结合，发动机60的动力经第一离合器31直接传递给第一外齿圈13；电机70开启后，电机70的动力直接传递给第一太阳轮14；发动机60的动力和电机70的动力在第一行星轮12上进行耦合。It should be noted that, under the continuously variable transmission (ECVT) working condition, when the speed is changed, one of the power of the engine 60 and the motor 70 needs to be kept constant, that is, the speed of the motor 70 and the speed of the motor 70 should be increased while the speed of the engine 60 remains unchanged. The rotation speed of the engine 60 is increased while the rotation speed of the motor 70 remains unchanged, and the power coupling between the two is finally realized. Specifically, the first clutch 31 is combined, and the power of the engine 60 is directly transmitted to the first outer ring gear 13 through the first clutch 31; after the motor 70 is turned on, the power of the motor 70 is directly transmitted to the first sun gear 14; the power of the engine 60 It is coupled with the power of the motor 70 on the first planetary gear 12 .
如图10所示，为电停车发电的动力传递路径示意图。其中，加粗的实线为动力传递的路径，具体的控制方法如下：As shown in FIG. 10 , it is a schematic diagram of a power transmission path for electric parking power generation. Among them, the bold solid line is the path of power transmission, and the specific control method is as follows:
在第二离合器32结合、第一离合器31断开以及第一制动器41和第二制动器42同时断开的情况下，开启发动机60和电机70，发动机60的动力经第二行星排和第一行星排后传递至电机70，实现停车发电。When the second clutch 32 is combined, the first clutch 31 is disconnected, and the first brake 41 and the second brake 42 are disconnected simultaneously, the engine 60 and the motor 70 are turned on, and the power of the engine 60 passes through the second planetary row and the first planetary row. Pass it to the motor 70 after being discharged to realize power generation after parking.
需要说明的是，停车驻车状态下，第二外齿圈23和第一行星架11均与输出轴51连接，故第二外齿圈23和第一行星架11转速为0。第二离合器32结合，发动机60动力经过第二离合器32传递至第二行星架21，发动机60动力经第二太阳轮24传递给第一外齿圈13，第二外齿圈23最终驱动第一太阳轮14转动，实现电机70的发电。It should be noted that, in the parking state, both the second outer ring gear 23 and the first planet carrier 11 are connected to the output shaft 51 , so the rotation speed of the second outer ring gear 23 and the first planet carrier 11 is 0. The second clutch 32 is combined, the power of the engine 60 is transmitted to the second planet carrier 21 through the second clutch 32, the power of the engine 60 is transmitted to the first outer ring gear 13 through the second sun gear 24, and the second outer ring gear 23 finally drives the first The sun gear 14 rotates to realize the power generation of the motor 70 .
