Frame 13；Power is passed to high-speed planets 10, reverse planetary gear 15 and low-speed planets by planet carrier 13 simultaneously by planet wheel spindle 7
21；Because brake disc 35 is in free rotary state, and then high speed gear 12 is in free rotary state, and then high speed internal tooth
Circle 11 is in free rotary state；Further, since the brake disc 35 of low brake 4 is in free rotary state, and then low speed
Shelves gear 23 is in free rotary state, and then the low-speed sun pinion 17 of 22 connection fixed thereto of low or first gear connecting shaft is in freely
Rotary state；Therefore, the power from planet carrier 13 provides reaction brake force by reverse clutch sun gear 14, and power is through reverse
On-off planet wheel 15 and the high-speed planets of connection fixed thereto 10 pass to high-speed sun pinion 9, the output of high-speed sun pinion 9 with it is defeated
Enter axle 29 and turn to opposite power, realize reversing clutch function.
