Above example is the optimum structure of the present invention, is not limiting the scope of the present invention；In connection side
The scheme adjusted in formula, the realization without influenceing this hair goal of the invention.
The fast gear power transmission line of the present embodiment：
The inside spin of power → torus axial direction 7 → torus of inner conical drogue axial direction 6 → torus of external conical sleeve axial direction external conical sleeve 6
The external spiral cam 1a of cam 6a → power transmission shaft 1 → power transmission shaft 1 exports power；
Now freewheel clutch surmounts, and resistance transfer route：External spiral cam 1a → circle of 1 → power transmission shaft of power transmission shaft 1
The inside spin cam 6a of ring body axial direction external conical sleeve 6 → torus axial direction external conical sleeve 6 → compression speed change butterfly spring；Power transmission shaft 1 passes through biography
The external spiral cam of moving axis 1 applies axial direction to the inside spin cam 6a and torus axial direction external conical sleeve 6 of torus axial direction external conical sleeve 6
Power simultaneously compresses speed change butterfly spring, when running resistance be increased to one timing, the axial force speed change butterfly spring, make torus axial direction inner conical drogue 7
Separated with torus axial direction external conical sleeve 6, power is transmitted by following routes, i.e., keeps off power transmission line slowly：
Power → torus axial direction inner conical drogue 7 → keeping off driving gear → the first gear gear slowly slowly → keeps off jackshaft → the second slowly
Outer ring 15 → freewheel clutch, 14 → pendulum-type of inner ring edge cam Meshing Pair of slow gear gear → freewheel clutch → cam pair →
External spiral cam → power transmission shaft of inside spin cam → power transmission shaft 1 of torus axial direction 6 → torus of external conical sleeve axial direction external conical sleeve 6
1 output power.
Slow gear power transmission line also passes through following route simultaneously：Pendulum-type edge cam Meshing Pair → cam pair → torus
Axial external conical sleeve 6 → compression speed change butterfly spring, prevent from keeping off appearance compression speed change butterfly spring reciprocating compression in transmission process slowly, so as to prevent
Torus axial direction inner conical drogue 7 and torus axial direction external conical sleeve 6 are bonded during slow shelves transmission.
There is above-mentioned transfer route to can be seen that the present invention operationally, the inner conical surface and annulus of torus axial direction inner conical drogue 7
The male cone (strobilus masculinus) of body axial direction external conical sleeve 6 is brought into close contact under the effect of speed change butterfly spring, forms the fluid drive of a holding certain pressure
Mechanism, and pressure needed for clutch engagement can be adjusted by increasing the axial width of speed change axle sleeve, reach transmission purpose,
Now, power drives torus axial direction inner conical drogue 7, torus axial direction external conical sleeve 6, power transmission shaft 1, power transmission shaft 1 is exported power inverse
Hour hands rotate；Freewheel clutch is now kept off slowly and is in surmounts state.
Resistance is more than driving force during motor vehicle starting, and resistance forces power transmission shaft 1 to rotate clockwise certain angle, in power transmission shaft
In the presence of 1 external spiral cam, torus axial direction external conical sleeve 6 compresses speed change butterfly spring；Torus axial direction external conical sleeve 6 and torus
Axial inner conical drogue 7 separates, synchronous, slow to keep off freewheel clutch engagement, and power drives the gear tooth slowly of torus axial direction inner conical drogue 7, first
Wheel, jackshaft, the second slow gear gear, the outer ring 15 of freewheel clutch, inner ring 14, pendulum-type edge cam Meshing Pair, annulus are kept off slowly
Body axial direction external conical sleeve 6 and power transmission shaft 1, power transmission shaft 1 is set to export power to keep off speed rotation slowly；Therefore, bottom gear is realized automatically
Start, shorten the starting time, reduce starting power.At the same time, speed change butterfly spring absorbs resistance of motion square energy, to recover fast
Keep off gear passing power and store standby potential energy.
After starting successfully, running resistance is reduced, when pressure caused by component is reduced to less than speed change butterfly spring, because being transported
Dynamic resistance is compressed and produces speed change butterfly spring pressure and discharge rapidly under promotion, completes the male cone (strobilus masculinus) and circle of torus axial direction external conical sleeve 6
The inner conical surface of ring body axial direction inner conical drogue 7 recovers to be brought into close contact state, and slow gear freewheel clutch, which is in, surmounts state.
During traveling, it is same as above with the change self shifter principle of the resistance of motion, the feelings of driving force need not be being cut
Variable block is realized under condition, makes whole locomotive operation steady, safe and low consumption, and also transfer route is simplified, and improves transmission efficiency.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the skill of the present invention
Art scheme is modified or equivalent substitution, and without departing from the spirit and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
