The fast gear power transmission line of the present embodiment:
Power → active friction part 18 → from 2 → axial cam of dynamic friction piece pair → (the second axial cam of cam sleeve 22
Auxiliary cam pair and the second circumferential cam sleeve) → 11 output power of transmission shaft power output member；
The second freewheel clutch surmounts at this time, and resistance transfer route: 11 → cam sleeve of power output member 22 → axial direction
Cam is secondary → from dynamic friction piece 2 → speed change disc spring；Power output member 11 applies axial direction to from dynamic friction piece 2 by axial cam pair
Power simultaneously compresses speed change disc spring, and when running resistance is increased to a timing, which overcomes speed change disc spring, make 18 He of active friction part
It is separated from dynamic friction piece 2, power is transmitted by following routes, i.e. bottom gear power transmission line:
Power → active friction part 18 → countershaft, 12 → bottom gear driving gear → second freewheel clutch outer ring 6b →
Inner ring 6a → main shaft 1 of second freewheel clutch → dynamic from 2 → axial cam of dynamic friction piece pair → 22 → transmission shaft of cam sleeve
11 output power of power output.
Bottom gear power transmission line also passes through following route: axial cam pair → become from dynamic friction piece 2 → compression simultaneously
Fast disc spring prevents occurring compression speed change disc spring reciprocating compression in bottom gear transmission process, thus when bottom gear being prevented to be driven actively

From dynamic friction piece 2, cam sleeve 22, make 22 output power of cam sleeve；The second freewheel clutch, which is in, at this time surmounts state.
Resistance is greater than driving force when motor vehicle starting, and resistance forces cam sleeve to turn an angle round about,
Under the action of axial cam pair, speed change disc spring is compressed from dynamic friction piece 2；It is separated from dynamic friction piece 2 and active friction part 18, together
Step, the engagement of the second freewheel clutch, output power is with the rotation of bottom gear speed；Therefore, bottom gear starting is realized automatically, is shortened
Starting time, reduce starting power.At the same time, speed change disc spring absorbs resistance of motion square energy, passes to restore fast gear gear
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 disc spring, because being transported
Dynamic resistance is compressed and generates speed change disc 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 → 22 → transmission shaft of cam sleeve power output member 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.
