Fast elastic element 2 is located at space of the supporting rack between transmission shaft and is coated at transmission shaft, compact-sized.
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 influencing this hair goal of the invention.
The fast gear power transmission line of the present embodiment：
The inside spin of power → torus axial direction inner conical drogue 5 → torus axial direction external conical sleeve 4 → torus axial direction external conical sleeve
External spiral 10 → transmission shaft of cam of cam 4a → transmission shaft 1 exports power；
Freewheel clutch surmounts at this time, and resistance transfer route：External spiral cam → torus of transmission shaft → transmission shaft
The inside spin cam of axial external conical sleeve → torus axial direction external conical sleeve → compression speed change butterfly spring；The outer spiral shell that transmission shaft passes through transmission shaft
Rotation cam applies axial force to the inside spin cam and torus axial direction external conical sleeve of torus axial direction external conical sleeve and compresses speed change butterfly
Spring, when running resistance is increased to a timing, which makes torus axial direction inner conical drogue and torus axial direction outer cone
Set separation, power are transmitted by following routes, i.e., keep off power transmission line slowly：
Power → torus axial direction inner conical drogue 5 → slow gear driving gear 9 → the first keeps off gear 21 → slow gear jackshaft 19 slowly
Outer ring 15 → freewheel clutch inner ring 14 → pendulum-type edge cam Meshing Pair of → the second slow gear 16 → freewheel clutch of gear →
The external spiral of inside spin cam 4a → transmission shaft 1 of cam pair → torus axial direction external conical sleeve 4 → torus axial direction external conical sleeve is convex
It takes turns 10 → transmission shaft and exports 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 4 → compression speed change butterfly spring prevents from keeping off appearance compression speed change butterfly spring reciprocating compression in transmission process slowly, to prevent
Torus axial direction inner conical drogue and the fitting of torus axial direction external conical sleeve when slow shelves transmission.
There is above-mentioned transfer route to can be seen that the present invention at runtime, the inner conical surface and annulus of torus axial direction inner conical drogue
The male cone (strobilus masculinus) of body axial direction external conical sleeve fits closely under the effect of speed change butterfly spring, forms the automatic speed variator of a holding certain pressure
Structure, and pressure needed for clutch engagement can be adjusted by increasing the axial width of speed change axle sleeve, reach transmission purpose, this
When, power drives torus axial direction inner conical drogue, torus axial direction external conical sleeve, transmission shaft, and transmission shaft output power is made to revolve counterclockwise
Turn；It keeps off freewheel clutch slowly at this time and is in and surmount state.
Resistance is more than driving force when motor vehicle starting, and resistance forces transmission shaft 1 to rotate clockwise certain angle, in transmission shaft
Under the action of 1 external spiral cam 10, torus axial direction external conical sleeve 4 compresses speed change butterfly spring；Torus axial direction external conical sleeve 4 and annulus
Body axial direction inner conical drogue 5 detaches, synchronous, slow to keep off freewheel clutch engagement, and power drives the gear slowly of torus axial direction inner conical drogue 5, first
Gear gear 16, the outer ring 15 of freewheel clutch, inner ring 14, the engagement of pendulum-type edge cam slowly of gear 21, slow gear jackshaft 19, second
Secondary, torus axial direction external conical sleeve 4 and transmission shaft 1 make transmission shaft 1 export power to keep off speed rotation slowly；Therefore, it realizes automatically
Bottom gear starts, and shortens the starting time, reduces starting power.At the same time, speed change butterfly spring absorbs resistance of motion square energy, is
Restore fast gear gear passing power and stores 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 generates speed change butterfly spring pressure and discharge rapidly under promotion, and the male cone (strobilus masculinus) and circle of torus axial direction external conical sleeve 4 are completed
The inner conical surface recovery of ring body axial direction inner conical drogue 5 fits closely state, and slow gear freewheel clutch, which is in, surmounts state.
In driving process, it is same as above with the variation self shifter principle of the resistance of motion, in the feelings that need not cut 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.
Finally illustrate, the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to compared with
Good embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present invention
Art scheme is modified or replaced equivalently, and without departing from the spirit of the technical scheme of the invention and range, should all be covered at this
In the right of invention.
