Graduating power stores standby potential energy.
After starting successfully, running resistance is reduced, when pressure caused by component is reduced to less than speed change spring, because being transported
Dynamic resistance is compressed and generates speed change spring pressure and discharge rapidly under promotion, completes to restore from dynamic friction piece 2 and active friction part 18
State is fitted closely, bottom gear freewheel clutch, which is in, surmounts state.
In driving process, as the variation self shifter principle of the resistance of motion is same as above, in the feelings for not needing cutting driving force
Variable block is realized under condition, keeps entire locomotive operation steady, safe and low consumption, and also transfer route is simplified, and transmission efficiency is improved.

Power → 18 → countershaft of the active friction part 12 → driving gear that reverses gear → driven gear → main shaft 1 that reverses gear → driven rubs
It wipes 2 → axial cam of part pair → cam sleeve, 22 → the first power output driving gear 11 and exports the power that reverses gear.
At this point, since the transmission ratio to reverse gear is greater than bottom gear transmission ratio, then the second freewheel clutch surmounts, and due to rotation
Reversely, the first freewheel clutch surmounts, and realizes reverse gear.
