The pushing out ring I 24 and pushing out ring II 28 be respectively provided with for backing roll both ends penetrate along II 28 circumference side of pushing out ring I 24 and pushing out ring
To annular groove (the annular groove 24a on pushing out ring I 24 is indicated in figure, on the annular groove 28a on pushing out ring II 28 and pushing out ring I 24
Ring channel structures it is similar and inside), 23 both ends of the backing roll are slidably matched with corresponding annular groove, i.e. the one of backing roll
End penetrates the annular groove 24a on pushing out ring I 24, and the other end penetrates the annular groove on pushing out ring II 28；Using the mounting structure of annular groove,
Simple in structure, assembly is easy, further such that the structure of freewheel clutch simplifies, reduces cost；Further include being located at outside pushing out ring I 24
The rolling bearing I 26 of side being supported between outer ring 14 and inner ring 15 and it is supported in outer ring 14 and interior positioned at the outside of pushing out ring II 28
Rolling bearing II 29 between circle 15；Stable support is formed, bite, the annular groove slot bottom and pushing out ring of the pushing out ring I 24 are avoided
II 28 annular groove slot bottom is equipped with axially extending bore, for that by lubricating oil, can be introduced by the axially extending bore and lubrication is discharged
Oil realizes preferable lubrication and cleaning, to ensure the operating of freewheel clutch.
Further include the baffle ring I 25 for being located at I 24 outside of pushing out ring and the baffle ring II positioned at II 28 outside of pushing out ring in the present embodiment
30, the baffle ring I 25 and baffle ring II 30 are respectively formed the interior heavy platform structure for being placed on outer ring, are formed and are supported to stablizing for outer ring, ensured
The stable operation of freewheel clutch itself；As shown, baffle ring I 25 and baffle ring II 30 pass through corresponding roller bearings respectively
In 16 outer circle of driving sleeve, as shown, baffle ring I 25 passes through rolling bearing II 29 by rolling bearing I 26 and baffle ring II 30
It is installed on driving sleeve 16 so that form stable relative motion between freewheel clutch inner ring and outer ring, reduce friction and card
Puckery generation.
In the present embodiment, the distribution of the axially extending bore 24b of the annular groove 24a slot bottoms of the pushing out ring I 24 and backing roll 23 and
Rolling element 31 corresponds to；It being capable of preferable relatively straightforward offer lubrication.
In the present embodiment, the diameter of the backing roll 23 is less than the one third of the diameter of rolling element 31, and rolling element is rolling
Column.
In the present embodiment, the supporting rack 4 for being provided with tubular structure is fixedly connected with active friction disk 7, the supporting rack is separate
One end of active friction disk 7, which is rotatably assorted, is supported in gearbox body, and the speed change elastic element 3 is located at supporting rack and transmission shaft 1
Between space and be coated at support shaft；As shown, in support shaft by it is left-to-right be equipped with freewheel clutch outer ring 14,

Frame 4 forms active friction disk 7 stable support, ensures transmission accuracy, meanwhile, speed change elastic element is located at supporting rack in transmission
Space between axis 1 and it is coated at support shaft, it is 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：
Outside inside spin cam → transmission shaft 1 of power → 7 → driven friction disk of active friction disk, 6 → driven friction disk 6
Spiral cam → transmission shaft 1 exports power；
Freewheel clutch surmounts at this time, and resistance transfer route：The external spiral cam of 1 → transmission shaft of transmission shaft 1 → driven
Inside spin cam → driven friction disk 6 of frictional disk 6 → compression speed change butterfly spring；The external spiral cam that transmission shaft 1 passes through transmission shaft 1
Inside spin cam and driven friction disk 6 to driven friction disk 6 apply axial force and compress speed change butterfly spring, when running resistance increases
To a timing, which makes active friction disk 7 and driven friction disk 6 detach, and power is passed by following routes
It passs, i.e., keeps off power transmission line slowly：
Power → active friction disk 7 → gear driving gear → the first keeps off gear slowly slowly → slow gear tooth of gear jackshaft → the second slowly
Outer ring 14 → freewheel clutch inner ring 15 → spiral prominence wheel set I 32 → driving sleeve, 16 → intermediate cam of wheel → freewheel clutch
External spiral cam → the transmission shaft 1 for covering inside spin cam → transmission shaft 1 of 21 → driven friction disk, 6 → driven friction disk 6 exports
Power.
Slow gear power transmission line also passes through following route simultaneously：Spiral prominence wheel set I → driving sleeve, 16 → intermediate cam
21 → driven friction disk 6 → compression speed change butterfly spring is covered, prevents from keeping off appearance compression speed change butterfly spring reciprocating compression in transmission process slowly, from
And active friction disk 7 and driven friction disk 6 are bonded when slow shelves being prevented to be driven.
There is above-mentioned transfer route to can be seen that the present invention at runtime, active friction disk 7 is with driven friction disk 6 in speed change
It is fitted closely 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, at this point, power drive active friction disk 7, from
Dynamic friction disk 6, transmission shaft 1 make transmission shaft 1 export power and rotate counterclockwise；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 1a, driven friction disk 6 compresses speed change butterfly spring；Driven friction disk 6 and active friction disk 7 detach,
Synchronous, slow to keep off freewheel clutch engagement, power drives active friction disk 7, first gear gear 19, slow gear jackshaft 17, second slowly
Slow gear gear 18, the outer ring 14 of freewheel clutch, inner ring 15, driving sleeve 16, intermediate cam set 21, driven friction disk 6 and biography
Moving axis 1 makes transmission shaft 1 export power to keep off speed rotation slowly；Therefore, bottom gear starting is realized automatically, when shortening starting
Between, reduce starting power.At the same time, speed change butterfly spring absorbs resistance of motion square energy, is stored to restore fast gear gear passing power
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, completes driven friction disk 6 and active friction disk 7 restores tight
Closely connected conjunction state, 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.
