Above embodiment is optimum structure of the present invention, is not limiting the scope of the present invention; The scheme that connection mode adjusts to some extent, and do not affect the realization of this goal of the invention.
The fast gear power transmission line of the present embodiment:
External spiral cam → transmission shaft 1 outputting power of the inside spin cam → transmission shaft 1 of power → active friction disk 5 → driven friction disk 4 → driven friction disk 4;
Now overriding clutch surmounts, and resistance transfer route: inside spin cam → driven friction disk 4 → compression speed change butterfly spring of the external spiral cam → driven friction disk 4 of transmission shaft 1 → transmission shaft 1; Transmission shaft 1 applies axial force by the external spiral cam of transmission shaft 1 to the inside spin cam of driven friction disk 4 and driven friction disk 4 and compresses speed change butterfly spring, when resistance to motion is increased to a timing, this axial force speed change butterfly spring, active friction disk 5 is separated with driven friction disk 4, power is transmitted by following route, namely keeps off power transmission line slowly:
Power → active friction disk 5 → keep off slowly driving gear → the first keeps off gear → keep off external spiral cam → transmission shaft 1 outputting power that tween drive shaft → the second keeps off the inside spin cam → transmission shaft 1 of outer ring 15 → overriding clutch inner ring, 14 → spiral prominence wheel set, I → intermediate cam cover, 20 → cam pair, I → driven friction disk, the 4 → driven friction disk 4 of gear → overriding clutch slowly slowly slowly.

Above-mentioned transfer route is had to find out, the present invention operationally, active friction disk 5 and driven friction disk 4 fit tightly under the effect of speed change butterfly spring, form the automatic transmission that keeps certain pressure, and the required pressure of power-transfer clutch engagement can be adjusted by the axial width increasing speed change axle sleeve, reach transmission object, now, power drives active friction disk 5, driven friction disk 4, transmission shaft 1, makes transmission shaft 1 outputting power left-hand revolution; Now keep off overriding clutch to be slowly in and to surmount state.
During motor vehicle starting, resistance is greater than propulsive effort, and resistance forces transmission shaft 1 to rotate clockwise certain angle, and under the effect of the external spiral cam 1a of transmission shaft 1, driven friction disk 4 compresses speed change butterfly spring; Driven friction disk 4 is separated with active friction disk 5, synchronously, slow gear overriding clutch engagement, power drives active friction disk 5, first slowly gear gear 20, slow gear tween drive shaft 18, second outer ring 15 of gear gear 19, overriding clutch, inner ring 14, intermediate cam cover 20, driven friction disk 4 and transmission shaft 1 slowly, and transmission shaft 1 outputting power is rotated to keep off speed slowly; Therefore, automatically achieve bottom gear and start, shorten cranking time, decrease starting power.Meanwhile, speed change butterfly spring absorbs movement resistor moment energy, stores standby potential energy for recovering gear transferring power soon.
Start successfully, resistance to motion reduces, when component is reduced to less than the pressure that speed change butterfly spring produces, produce under speed change butterfly spring pressure discharges promotion rapidly because the compression of passive movement resistance, what complete driven friction disk 4 fits tightly state with active friction disk 5 recovery, and slow gear overriding clutch is in and surmounts state.
In driving process, along with the change self shifter principle of resistance of motion is the same, realizing variable block when not needing to cut off propulsive effort, make whole locomotive operation steady, safe and low consumption, and transfer route being simplified, improving driving efficiency.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
