l gear: an L-gear clutch (C6) on a four-axis (S4) is combined, a LL-gear clutch (C5), an M-gear clutch (C7) on a three-axis (S3) and an H-gear clutch (C8) on the four-axis (S4) are separated, and power is divided from the three-axis (S3), an L-gear driving gear (22), an L-gear driven gear (23), the L-gear clutch (C6) and the four-axis (S4);
m gear: the clutch C7 of M gear on the triaxial (S3) is combined, the clutch C5 of LL gear on triaxial (S3), the clutch C6 of L gear on the four-axis (S4) and the clutch C8 of H gear are separated, the power is from triaxial (S3) to M gear clutch C7 to M gear driving gear 18 to M gear driven gear 19 to four-axis (S4);
h gear: the H gear clutch (C8) on the four-axis (S4) is combined, the LL gear clutch (C5), the M gear clutch (C7) on the three-axis (S3) and the L gear clutch (C6) on the four-axis (S4) are separated, and power is from the three-axis (S3), the H gear driving gear (16), the H gear driven gear (17), the H gear clutch (C8) and the four-axis (S4).
