High-power stepless transmission
The invention relates to a tooth chain type stepless transmission for an automobile. A tooth chain is arranged around a plurality of planetary gears which can unidirectionally rotate; all the planetary gears can move in a corresponding radial chute on a drive wheel; and stepless transmission is realized by changing the revolution diameter of the planetary gears. An unlocking key is arranged in a one-way clutch of each planetary gear; and when the tooth chain and the planetary gears are meshed and separated, the unlocking key can be driven so that the clutch is maintained in a one-way locking state or unlocking state. The invention breaks through the traditional theory that the stepless transmission is only friction power transmission, solves the problem of carrying out stepless transmission by utilizing a gear, can effectively improve the transfer power of the stepless transmission and has the advantages of large force transmission, high rotating speed, stable running, reliable work, and the like.
