Working principle of the present invention is as follows;
1. the first order 1 and the second level their working principle of 2 full-automatic stepless transmissions are identical, and different is the member shape, and bear torque ability difference.
2. the free type full automatic non-stage transmission gear drive has general gear mechanism engagement, transferring power, change moment of torsion, the default general performance of velocity ratio excursion.Power on the driving gear sense of rotation after free disc mechanism transmits, remains in the same way stressed sense of rotation of driven axle and driving shaft sense of rotation.Under the effect of driving gear, free disc mechanism inner planet gear also acquires the rotating force consistent with the driving shaft sense of rotation when acquiring spinning motion, and this rotating force makes free disc mechanism all the time, has the effect of rotating with moving passive ring gear.And in exterior epicyclic gear and interactional while of passive ring gear, the reaction force of generation makes free disc mechanism acquire a rotating force with the driving shaft direction of rotation.
3. on free disc mechanism exterior epicyclic gear and passive ring gear contact points, utilize active force to equal reaction force, realize moving resistance amount of free disc mechanism and driven disc mechanism and equivalent distribution motion.
4. the resistance that frictional force that free disc mechanism produces and driving gear power are formed free disc mechanism counter-rotation.The resistance on the driven axle sense of rotation is formed in frictional force in the driven axle mechanism and external resistance.Active force equals reaction force on exterior epicyclic gear on the free disc mechanism and passive ring gear contact points, and when power transmission took place, in the time, free disc mechanism and driven axle mechanism realized moving resistance amount and equivalent distribution rotation at certain phase.
Moving resistance amount and equivalent distribution equations formula are as follows;
Represent that with v speed .a represents that acceleration .t express time .F represents that active force .f represents that frictional force and resistance .m represent quality.
At free disc mechanism and driven axle mechanism initial velocity is zero, and when driving shaft power remained unchanged, free disc mechanism and driven axle mechanism can get according to mechanics principle under the effect of directed force F and reaction force-F;

Under the situation that driving shaft power remains unchanged, free disc mechanism and driven axle mechanism, in the time in stage, move resistance amount and distribution according to moving resistance amount and equivalent distribution equations, they obtain rotational velocity separately respectively, at this moment free disc mechanism rotational velocity has reached the rotational velocity ultimate state, and enters limit rotational velocity changes phase.
5. remain unchanged at driving shaft power, free disc mechanism after moving resistance amount and equivalent are distributed, the rotational velocity that reaches capacity, and enter limit rotational velocity changes phase.The velocity variations of free disc mechanism in limit rotational velocity changes phase is limit rotational velocity state all the time.Free disc mechanism limit rotational velocity variation and driving shaft and driven axle rotational velocity change, and following six kinds of corresponding changes are arranged:
(1). when driving shaft and driven axle rotational velocity remained unchanged, free disc mechanism limit rotational velocity remained unchanged.Free type full automatic non-stage transmission is in limit rotational velocity and keeps the stage.
(2). when the driving shaft rotational velocity remains unchanged, in the scope of driving shaft rotational velocity greater than the driven axle rotational velocity, when the driven axle rotational velocity changes, free disc mechanism limit rotational velocity, will be in time corresponding to moving along with the increase of driven axle rotational velocity, on former limit rotational velocity, increase and driven axle sense of rotation rotational velocity in opposite directions.On the contrary, along with the reducing and timely corresponding reserve motion of driven axle rotational velocity, on former limit rotational velocity, reduce and driven axle sense of rotation rotational velocity in opposite directions.
(3). when the rotational velocity of driving shaft and driven axle reached same speed, free disc mechanism limit rotational velocity and driving shaft and driven axle rotational velocity reached sync state.At this moment, planetary pinion that freely coils and planet pin relatively freely coil and are state of rest.
(4). when the driving shaft rotational velocity is lower than the driven axle rotational velocity, under the gear drive effect, free disc mechanism is on synchronous limit rotational velocity basis, to surmount the driven axle rotational velocity, driven axle, free disc mechanism and driving shaft transmission simultaneously forms disengaged position, and at this moment speed changer possesses the automatic clutch function.
(5). when the driving shaft outputting power hour, behind free disc mechanism transmission bending moment, the power that acquires on the driven axle is less than the repose resistance on the driven axle, driven axle will keep its state of rest.At this moment the rotational velocity of driving shaft is by the counter-rotational running of free disc mechanism, make the free disc mechanism rotational velocity that reaches capacity, and keep its limit rotational velocity, the transmission of driving shaft and driven axle form disengaged position, and at this moment speed changer possesses the automatic clutch function.
(6). free type full automatic non-stage transmission velocity ratio excursion.
The default fixed drive ratio of the first order 1 full-automatic stepless transmission is: when freely coiling 13 relative fixed on case of transmission the time, at this moment the velocity ratio of driving mechanism is a fixed drive ratio. (use i

When planetary gear set 10,11 and gear shaft 24 were state of rest with respect to free dish 13, the rotation of driving shaft 3, free disc mechanism and driven axle 4 formed the state that is synchronized with the movement, and driving shaft 3 is 1 with the velocity ratio of driven axle 4: 1.
When driving shaft 3 outputting powers hour, driving shaft 3 forms disengaged position with the transmission of driven axle 4, driven axle 4 keeps state of rest, at this moment, driving shaft 3 is zero with the velocity ratio of driven axle 4.So, the excursion of the first order 1 full-automatic stepless transmission velocity ratio is 0 to i

When cylindrical planetary gear group 19,20 was state of rest with respect to free dish 21, the rotation of driving shaft 4, free disc mechanism and driven axle 5 formed the state that is synchronized with the movement, and driving shaft 4 is 1 with the velocity ratio of driven axle 5: 1.
When driving shaft 4 obtains power hour, driving shaft 4 forms disengaged position with the transmission of driven axle 5, and driven axle 5 keeps state of rest, and at this moment, driving shaft 4 is zero with the velocity ratio of driven axle 5.So, the excursion of the second level 2 full-automatic stepless transmission velocity ratios is 0 to i

Working procedure of the present invention is as follows:
When first 3 is rotated, drive initiatively that cone gear 6 rotates with speed, initiatively cone gear 6 acts on and freely coil on 13 female cone planetary pinion 10 and do spinning motion, simultaneously, free disc mechanism produced the rotatory force of rotating around driving shaft 3---promptly follow power.Initiatively the power on the cone gear 6 promptly is the power of the required transmission of free disc mechanism, be again free disc mechanism rotation with power or resistance amount resistance.Female cone planetary pinion 10 is given outer cone planetary pinion 11 through gear shaft 24 with transmission of power, and act on circular cone ring gear 12, on cone planetary gear 11 and circular cone ring gear 12 contact pointss, be subjected to the rotation power of outer cone planetary pinion 11 and the power of following of free disc mechanism rotation simultaneously outside---be composite force.Outside on the contact points of cone planetary gear 11 and cone ring gear 12, produce a pair of active force and reaction force, because the effect of active force and reaction force, motion of mechanism enters into moving resistance amount of phase I and equivalent assigning process on free disc mechanism and the driven axle, in this course, initiatively the power of cone gear 10 promptly is power, is again resistance amount resistance.After phase I finished, free disc mechanism rotational velocity reached and enters into second stage extreme sport velocity variations process, and in this course, initiatively the power on the cone gear 10 promptly is power, is again with power.Under the situation that first 3 power and rotational velocity remain unchanged, driven axle 4 is owing to be subjected to the variation of external resistance, constantly change rotational velocity, make the extreme sport speed of free disc mechanism change thereupon, the size that causes acting on the composite force on the passive circular cone ring gear 12 changes thereupon, changes its moment of torsion and velocity ratio simultaneously.
When first 3 outputting power hour, by the running of free disc mechanism, when being delivered to power on second 4, can not be second 4 and rotate that at this moment first 3 and second 4 will possess automatic disengaged position less than its repose resistance.If first 3 power increases, make the power that is delivered on second 4 greater than its repose resistance, so, first 3 and second 4 will possess automatic bonding state, realize transmission of power.
When the first 3 less or unpowered output of outputting power, first 3 rotational velocity is less or do not have a rotation, be in for second 4 and surmount first 3 and rotate, by the running of free disc mechanism between active cone gear 6 and passive circular cone ring gear 12, make the rotational velocity of free disc mechanism surmount the rotational velocity of passive ring gear 12, at this moment, first 3 and second 4 runnings by free disc mechanism make them possess automatic disengaging drive state.After first 3 power recovers, will recover transmission automatically, realize automatic combination.
When first 3 unpowered output or outputting power hour, free type full automatic non-stage transmission will be realized disengaging automatically, transmission runs out of steam.When first 3 determined power output being arranged, combination recovers transmission of power automatically, and possesses the effect of unidirectional delivery power.Free type full automatic non-stage transmission has the effect of full-automatic stepless change, clutch and unidirectional delivery power.Second level full-automatic stepless transmission and its working principle of first order full-automatic stepless transmission and performance are identical.
