As shown in Figure 1-Figure 3, present embodiments provide a kind of contiuously variable transmission, including the first support base, the second support base,
Mobile fluted disc 300, linear drives component, locating part, power input module 700, power output component 600 and multiple lever and gear wheels
400.Wherein, the 200 opposite and interval setting of the first support plate 100 and the second support plate, mobile fluted disc 300 are located at the first support plate
100 and second between support plate 200, by linear drives Component driver its between the first support plate 100 and the second support plate 200
It moves back and forth.Locating part is used to carry out rotary spacing to mobile fluted disc 300, it is made to be only capable of in the first support plate 100 and second
It is moved between support plate 200.
Please continue to refer to Fig. 1-Fig. 3, in the present embodiment, power input module 700 includes being articulated in the first support plate 100
Multiple planet input gears 710, the quantity Matching of the quantity and lever and gear wheel 400 of planet input gear 710.Power output component
600 include that multiple planetary output gears 610 for being articulated in the second support plate 200 are based on each planetary output gear 610 while engaging
Tooth form output, each planetary output gear 610 is along uniformly distributed with the center annular of tooth form output.The of each lever and gear wheel 400
One end respectively with the universal connection in eccentric position of each planet input gear 710, second end respectively with each planetary output gear 610
The universal connection in centre, and at least one of universal junction in both ends is arranged to stretch along the axial direction of lever and gear wheel 400
Contracting, each lever and gear wheel 400 are engaged between its first end with the gear segment of second end with the tooth form of mobile fluted disc 300.Linear drives
Component (not shown) and locating part are installed in the first support plate 100, alternatively, be installed in the second support plate 200,
Alternatively, simultaneously in the first support plate 100 and the second support plate 200.
When the contiuously variable transmission works, power is inputted by each planet input gear 710, drives lever and gear wheel connected to it
400 movements.Due to the universal connection in eccentric position of the first end and corresponding each planet input gear 710 of each lever and gear wheel 400,
Centre with each planetary output gear 610 is also universal connection, and at least one of universal connecting portion can be along thick stick
The axial stretching of bar gear 400 so that during planet input gear 710 rotates one week, each lever and gear wheel 400 is in space
In movement locus be taper (as shown in Figure 4).By the position-limiting action of locating part, the rotation of mobile fluted disc 300 is limited,
During one of lever and gear wheel 400 engage with mobile fluted disc 300, rotation will occur for lever and gear wheel 400, to driving and
Its planetary output gear 610 connected rotates, and then realizes the drive pair the tooth form output being meshed with planetary output gear 610
It is dynamic.
During the lever and gear wheel 400 is rotated further, limited by its movement locus, the lever and gear wheel 400 with
The number of teeth of the engagement simultaneously of mobile fluted disc 300, which will be reduced, even to be detached, and one in remaining lever and gear wheel 400 will be with movement
Fluted disc 300 engages, and makees movement identical with a upper lever and gear wheel 400, continues to drive to tooth form output to realize.By
It is uniformly distributed along the center annular of tooth form output in each planetary output gear 610 so that real under the action of each lever and gear wheel 400
The Continuous Drive to tooth form output is showed.
When linear drives Component driver moves fluted disc 300 towards close to the movement of the side of planet input gear 710, due to
The movement locus line of lever and gear wheel 400 at this time is longer (to make section, lever and gear wheel 400 moves rail to move 300 place plane of fluted disc
The cross-sectional area of mark is larger), such as the circle a in Fig. 7 so that number of teeth when lever and gear wheel 400 is engaged with mobile fluted disc 300 compared with
It is more, so that lever and gear wheel 400 can turn over larger angle in rotation, so that tooth form output can be in short-term
Interior quick rotation realizes the high rotating speed power output of contiuously variable transmission；When 300 court of linear drives Component driver movement fluted disc
When being moved to the side of close planetary output gear 610, since the movement locus line of lever and gear wheel 400 at this time is shorter (with movement
300 place plane of fluted disc makees section, and the cross-sectional area of 400 movement locus of lever and gear wheel is smaller), such as the circle b in Fig. 7 so that
Number of teeth when lever and gear wheel 400 is engaged with mobile fluted disc 300 is less, so that lever and gear wheel 400 can be turned in rotation
Smaller angle so that tooth form output can slow rotation, realize the slow-speed of revolution power output of contiuously variable transmission.
The contiuously variable transmission utilizes the alternating movement of lever and gear wheel 400, realizes the continuous power output of tooth form output,
Meanwhile using the change in location of mobile fluted disc 300 and 400 meshing point of lever and gear wheel, cutting for its high rotating speed and the slow-speed of revolution is realized
It changes.The contiuously variable transmission is simple in structure, and scheme is easily achieved, and cost is relatively low, has higher market economy value, for power
The development of drive apparatus is of great significance.
It should be noted that in the present embodiment, " lever and gear wheel 400 " refers to：It is formed using at mobile fluted disc 300
Fulcrum realize the movement similar to lever principle, also, be additionally provided with tooth form in the periphery of the lever.
As shown in Figure 5 and Figure 6, in order to ensure the positive engagement of each lever and gear wheel 400 and mobile fluted disc 300, to ensure
The reliability that power transmits, in the present embodiment, the inside tooth form of mobile fluted disc 300 is center vertical, the inclined setting shape in both sides
Formula.Such setting so that lever and gear wheel 400, can be with the wheel in mobile fluted disc 300 while coning motion in making Fig. 4
