Claim:
1. A continuously variable transmission comprising: a housing; an input assembly rotatably coupled to the housing, the input assembly comprising: a driven assembly rotatably received in the housing and positioned opposite the input assembly, the driven assembly comprising: an output assembly rotatably coupled to the housing, the output assembly comprising: a speed changing rod movably coupled with the housing at one end, and another end of the speed changing rod coupled to the power output shaft, wherein the first friction member and the second friction member are configured to rotate the power output shaft, and a transmission ratio of continuously variable transmission is adjustable by moving the speed changing rod to change a vertical distance between the rotational wheel and the power input shaft, the input assembly further comprises a drive gear non-rotatably sleeved on the power input shaft, the drive gear is spaced from the first friction member, the first friction member is positioned between the drive gear and the power output shaft the driven assembly further comprises a driven gear non-rotatably sleeved on the rotation shaft, the driven gear is spaced from the second friction member, the second friction member is positioned between the driven gear and the power output shaft; the continuously variable transmission further comprises a first transmission assembly meshed with the drive gear and a second transmission assembly meshed with the driven gear, both the first transmission assembly and the second transmission assembly are rotatably received in the housing, the first transmission assembly comprises a first transmission shaft, a first transmission gear, and the second transmission gear, the first transmission shaft rotatably passing through the housing, the first transmission gear and the second transmission gear are non-rotatably sleeved on the first transmission shaft and spaced from each other; the first transmission gear is meshed with the drive gear, and the second transmission gear is meshed with the second transmission assembly, the first transmission shaft is substantially parallel to the power input shaft and the rotation shaft.
