[0036] In the LL gear position, the eighth wet clutch C8 and the ninth wet clutch C9 are engaged, the seventh wet clutch C7 and the tenth wet clutch C10 are disengaged, and the power is transmitted from the fourth shaft S4 → the thirteenth gear 13 → the fourteenth gear 14 → the ninth wet clutch C9 → the sixteenth gear 16 → the fifteenth gear 15 → the eighth wet clutch C8 → the seventeenth gear 17 → the eighteenth gear 18 → the fifth shaft S5 → the twentieth gear 20 → the nineteenth gear 19 → the twenty-second gear 22 → the twenty-first gear 21 → the power output shaft S7.

[0037] In the L gear position, the ninth wet clutch C9 and the tenth wet clutch C10 are engaged, the seventh wet clutch C7 and the eighth wet clutch C8 are disengaged, and the power is transmitted from the fourth shaft S4 → the thirteenth gear 13 → the fourteenth gear 14 → the ninth wet clutch C9 → the tenth wet clutch C10 → the fifth shaft S5 → the twentieth gear 20 → the nineteenth gear 19 → the twenty-second gear 22 → the twenty-first gear 21 → the power output shaft S7.

[0038] In the H gear position, the seventh wet clutch C7 and the eighth wet clutch C8 are engaged, the ninth wet clutch C9 and the tenth wet clutch C10 are disengaged, and the power is transmitted from the fourth shaft S4 → the seventh wet clutch C7 → the eighth wet clutch C8 → the seventeenth gear 17 → the eighteenth gear 18 → the fifth shaft S5 → the twentieth gear 20 → the nineteenth gear 19 → the twenty-second gear 22 → the twenty-first gear 21 → the power output shaft S7.

[0039] In the HH gear position, the seventh wet clutch C7 and the tenth wet clutch C10 are engaged, the eighth wet clutch C8 and the ninth wet clutch C9 are disengaged, and the power is transmitted from the fourth shaft S4 → the seventh wet clutch C7 → the fifteenth gear 15 → the sixteenth gear 16 → the tenth wet clutch C10 → the fifth shaft S5 → the twentieth gear 20 → the nineteenth gear 19 → the twenty-second gear 22 → the twenty-first gear 21 → the power output shaft S7.

[0040] After the power reaches the power output shaft S7, it finally reaches the input end of the central drive of the rear axle.

[0041] In short, this full power shift transmission forms 16 forward gears and 16 reverse gears through fewer gear combinations. This structure is compact, cost-saving, has a short shift time, and greatly improves the operation efficiency.
