In the present embodiment, in the present embodiment, transmission bracket one end is connected formation transmission and coordinates with active friction disk 9, and being rotatably assorted away from one end of active friction disk 9 is supported in gearbox body 3, the described speed change flexible member 8 space between bracing frame and power transmission shaft 1 and be coated at power transmission shaft 1；As shown in the figure, it is provided with freewheel clutch outer ring 15, intermediate cam set 16, driven friction disk 6 and speed change flexible member 8 (the present embodiment uses speed change disc spring) by left-to-right on power transmission shaft 1, transmission bracket forms stable support to active friction disk 9, ensure transmission accuracy, simultaneously, the speed change flexible member 8 space between transmission bracket 8 and power transmission shaft 1 and be coated at power transmission shaft 1, compact conformation.
Above example is optimum structure of the present utility model, is not the restriction to this utility model protection domain；The scheme adjusted in connected mode, and do not affect the realization of this utility model purpose.
The present embodiment keep off power transmission line soon:
External spiral cam → the power transmission shaft 1 of the internal coiling cam → power transmission shaft 1 of power → active friction disk 9 → driven friction disk, 6 → driven friction disk 6 exports power；
Now freewheel clutch surmounts, and resistance transfer route: internal coiling cam → driven friction disk 6 → compression speed change butterfly spring of the external spiral cam → driven friction disk 6 of power transmission shaft 1 → power transmission shaft 1；Power transmission shaft 1 is applied axial force by the external spiral cam of power transmission shaft 1 to internal coiling cam and the driven friction disk 6 of driven friction disk 6 and compresses speed change butterfly spring, when running resistance is increased to a timing, this axial force speed change butterfly spring, active friction disk 9 and driven friction disk 6 is made to separate, power is transmitted by following route, keeps off power transmission line the most slowly:
Power → active friction disk 9 → keep off slowly driving gear → the first keeps off the external spiral cam → power transmission shaft 1 of internal coiling cam → power transmission shaft 1 of outer ring 15 → freewheel clutch inner ring 14 → spiral prominence wheel set I → intermediate cam set 16 → cam pair I → driven friction disk, 6 → driven friction disk 6 that gear → keep off slowly jackshaft → the second keeps off gear → freewheel clutch slowly slowly and exports power.
Slow gear power transmission line is the most also through following route: intermediate cam set 16 → driven friction disk, 6 → compression speed change butterfly spring, prevent from keeping off slowly and transmission process occurs compression speed change butterfly spring reciprocating compression, thus when preventing slow shelves transmission, active friction disk 9 and driven friction disk 6 are fitted.
Above-mentioned transfer route is had to can be seen that, this utility model is operationally, active friction disk 9 fits tightly under speed change butterfly spring effect with driven friction disk 6, form an automatic transmission keeping certain pressure, and clutch engagement desirable pressure can be adjusted by increasing the axial width of speed change axle sleeve, reach transmission purpose, now, power drives active friction disk 9, driven friction disk 6, power transmission shaft 1, makes power transmission shaft 1 export power and rotates counterclockwise；The most slowly gear freewheel clutch is in and surmounts state.
During motor vehicle starting, resistance is more than driving force, and resistance forces power transmission shaft 1 to rotate clockwise certain angle, and under the effect of the external spiral cam 1a of power transmission shaft 1, driven friction disk 6 compresses speed change butterfly spring；Driven friction disk 6 and active friction disk 9 separate, synchronize, slow gear freewheel clutch engagement, power drives active friction disk 9, first gear gear 10 slowly, slow gear jackshaft 11, second gear gear 12 slowly, the outer ring 15 of freewheel clutch, inner ring 14, intermediate cam set 16, driven friction disk 6 and power transmission shaft 1, makes power transmission shaft 1 export power and rotates with slow gear speed；Therefore, it has been automatically obtained bottom gear starting, has shortened the starting time, decreased starting power.Meanwhile, speed change butterfly spring absorbs movement resistor moment energy, stores standby potential energy for recovering fast gear gear transmission power.
After starting successfully, running resistance reduces, when pressure produced by component is reduced to less than speed change butterfly spring, produce speed change butterfly spring pressure discharge rapidly under promotion because of the compression of passive movement resistance, complete driven friction disk 6 fits tightly state with active friction disk 9 recovery, and slow gear freewheel clutch is in and surmounts state.
In driving process, along with the resistance of motion change self shifter principle ibid, in the case of need not cut off driving force, realize variable block, make whole locomotive operation steady, safe and low consumption, and transfer route is simplified, and improves transmission efficiency.
Finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent, without deviating from the spirit and scope of technical solutions of the utility model, it all should be contained in the middle of right of the present utility model.
