Gear 41- differential gear 42- differential mechanism 40, wheel 101.
Similarly it is found that the power transfer path of engine 30 is the second axis of I-first clutch of first axle C1- II-when second gear
The 5th V-output of axis of the 4th axis IV-two gear driving gear 2a- second gear driven gear the second synchronizer of 2b- B- of second clutch C2-
Axis side gear 41- differential gear 42- differential mechanism 40, wheel 101.
The power transfer path of engine 30 is II-the second clutch of the second axis of I-first clutch of first axle C1- when three gears
Device C2- third axis III-three keeps off driving gear 3a- tri- and keeps off the 5th axis V-output shaft side gear of the first synchronizer of driven gear 3b- A-
41- differential gear 42- differential mechanism 40, wheel 101.
The power transfer path of engine 30 is II-the second clutch of the second axis of I-first clutch of first axle C1- when four gears
The 4th axis IV-four of device C2- keeps off driving gear 4a- tetra- and keeps off the 5th axis V-output shaft side gear of the second synchronizer of driven gear 4b- B-
41- differential gear 42- differential mechanism 40, wheel 101.
