Fast elastic element is located at space of the support frame between transmission shaft and is coated at transmission shaft, compact-sized.
Above embodiments are optimum structure of the invention, are 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 shelves power transmission line of the present embodiment:
Power → torus axial direction inner conical drogue 5 → torus axial direction external conical sleeve 4 → torus axial direction external conical sleeve inside spin
Cam 4a → transmission shaft 1 external spiral cam 10 → transmission shaft output power;
Freewheel clutch surmounts at this time, and resistance transfer route:Transmission shaft → transmission shaft external spiral cam → torus
The inside spin cam of axial external conical sleeve → torus axial direction external conical sleeve → compression speed change butterfly spring;Transmission shaft passes through the outer spiral shell of 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., slow shelves power transmission line:
The slow shelves gear of power → torus axial direction inner conical drogue 5 → slow shelves driving gear 9 → the first 21 → slow shelves jackshaft 19
Outer ring 15 → freewheel clutch inner ring 14 → spiral prominence, I → intermediate cam of wheel set of → the second slow 16 → freewheel clutch of shelves gear
The inside spin cam 4a → transmission shaft 1 for covering 20 → cam pair, I → torus axial direction external conical sleeve 4 → torus axial direction external conical sleeve is outer
Spiral cam 10 → transmission shaft output power.
Slow shelves power transmission line also passes through following route simultaneously:Intermediate cam set 20 → torus axial direction external conical sleeve 4 →
Speed change butterfly spring is compressed, prevents occurring compression speed change butterfly spring reciprocating compression in slow shelves transmission process, thus circle when slow shelves being prevented to be driven
Ring body axial direction inner conical drogue and the fitting of torus axial direction external conical sleeve.
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, revolves transmission shaft output power counterclockwise
Turn;Slow shelves freewheel clutch, which is in, at this time surmounts state.
Resistance is greater 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 separates, synchronous, and slow shelves freewheel clutch engagement, power drives torus axial direction inner conical drogue 5, the first slow shelves
Gear 21, slow shelves jackshaft 19, the second slow shelves gear 16, the outer ring 15 of freewheel clutch, inner ring 14, intermediate cam set 20, circle
Ring body axial direction external conical sleeve 4 and transmission shaft 1 rotate 1 output power of transmission shaft with slow notch speed degree;Therefore, low speed is realized automatically
Shelves start, and shorten the starting time, reduce starting power.At the same time, speed change butterfly spring absorbs resistance of motion square energy, to restore
Fast shelves gear transmitting power 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 shelves freewheel clutch, which is in, surmounts state.
In driving process, as the variation fluid drive principle of the resistance of motion is same as above, in the feelings for not needing cutting driving force
Shift 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, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the spirit and scope of the technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
