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 shelves power transmission line of the present embodiment:
Outside inside spin cam → power transmission shaft 1 of power → 6 → driven friction disk of active friction disk, 5 → driven friction disk 5
Spiral cam → power transmission shaft 1 exports power;
Now freewheel clutch surmounts, and resistance transfer route:The external spiral cam 1a of 1 → power transmission shaft of power transmission shaft 1 → from
Inside spin cam 5a → driven friction disk 5 of dynamic friction disk 5 → compression speed change butterfly spring;The external spiral that power transmission shaft 1 passes through power transmission shaft 1
Cam applies axial force to the inside spin cam and driven friction disk 5 of driven friction disk 5 and compresses speed change butterfly spring, works as running resistance
A timing is increased to, the axial force speed change butterfly spring, separates active friction disk 6 and driven friction disk 5, power passes through following routes
Transmit, i.e., slow shelves power transmission line:
Outer ring 8 → freewheel clutch inner ring 9 of power → active friction disk 6 → slow shelves driving gear → freewheel clutch →
External spiral cam 1a → power transmission shaft of inside spin cam 5a → power transmission shaft 1 of cam pair → 5 → driven friction disk of driven friction disk 5
1 output power.
Slow shelves power transmission line also passes through following route simultaneously:Cam pair → driven friction disk 5 → compression speed change butterfly spring,
Prevent occurring compression speed change butterfly spring reciprocating compression in slow shelves transmission process, during so as to prevent that slow shelves are driven active friction disk 6 and from
Dynamic friction disk 5 is bonded.

It is brought into close contact under butterfly spring effect, forms the automatic transmission of a holding certain pressure, and can be by increasing variable-speed shaft
The axial width of set adjusts pressure needed for clutch engagement, reaches transmission purpose, now, power drive active friction disk 6, from
Dynamic friction disk 5, power transmission shaft 1, power transmission shaft 1 is set to export power rotate counterclockwise;Now slow shelves freewheel clutch, which 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 1a, driven friction disk 5 compresses speed change butterfly spring;Driven friction disk 5 and active friction disk 6 separate,
It is synchronous, slow shelves freewheel clutch engagement, power drive active friction disk 6, slow shelves driving gear 19, freewheel clutch outer ring 8,
Inner ring 9, driven friction disk 5 and power transmission shaft 1, power transmission shaft 1 is exported power and rotated with slow notch speed degree;Therefore, realize automatically low
Fast shelves start, and shorten the starting time, reduce starting power.At the same time, speed change butterfly spring absorbs resistance of motion square energy, is extensive
Multiple fast shelves gear passing 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 produces speed change butterfly spring pressure and discharge rapidly under promotion, completes driven friction disk 5 and active friction disk 6 recovers tight
Closely connected conjunction state, slow shelves freewheel clutch, which is in, surmounts state.
During traveling, it is same as above with the change fluid drive principle of the resistance of motion, the feelings of driving force need not be being cut
Shift 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.
