Problems solved by technology

[0004] However, the shifting bicycles with different gears are still step-shifting in essence, that is, they can only choose to change between fixed gears.
The cyclist can only change back and forth between a limited number of gears, but it cannot really meet the actual needs of the rider to "adjust to a random number of gears"

Embodiment Construction

[0065] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0066] Such as Figure 1 to Figure 26 As shown, the bicycle installed with the continuously variable transmission device in this embodiment includes the governor 100 and the continuously variable transmission device installed on the bicycle. The continuously variable transmission device includes the hub 1 and the hub cover 2 for connecting the spokes 101 , hub ring gear 3, transmission body 4, input disc 5, at least three input taper rotors 6, one output taper rotor 7, and main shaft 8; hub 1 and hub cover 2 are tightly fitted; hub 1 and hub cover are tightly fitted 2 forms a sealed shell, thereby sealing and supporting the transmission body 4, which can also prevent the entry of mud and sand during riding, making the riding process safer and smoother, and prolonging the use of the continuously variable transmission device lifespan; of which:...

Abstract

The invention relates to a bicycle provided with a stepless speed changing device. The bicycle provided with the stepless speed changing device comprises a speed regulator, and the bicycle further comprises the stepless speed changing device mounted on the bicycle; the stepless speed changing device comprises a hub, a hub cover, a hub gear ring, a speed changing body, an input disc, at least threeinput taper rotors, an output taper rotor and a spindle; the hub, the hub cover, the hub gear ring, the speed changing body, the input disc, the at least three input taper rotors, the output taper rotor and the spindle are used for being connected with a spoke; the hub is in fastening fit with the hub cover; speed changing shafts are arranged between the input taper rotors and the output taper rotor; the speed changing shafts make contact with the tapered surfaces of the input taper rotors and the tapered surface of the output taper rotor in a jacked mode and can move to different positions along the tapered surfaces of the input taper rotors and the tapered surface of the output taper rotor, so that stepless gear ratio changing is realized by adjusting the positions of the speed changingshafts on the tapered surfaces of the input taper rotors and the tapered surface of the output taper rotor, the situation that a rider can self choose the proper gear ratio for riding is met accordingly, and stepless speed changing of the bicycle is realized.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to a bicycle equipped with a continuously variable transmission device. Background technique [0002] Along with the continuous deepening of people's love for sports, cycling has gradually become a more and more popular form of entertainment and means of transportation, and cycling has also become a very popular competitive sport for amateurs and professional players. [0003] Most of the existing bicycles are variable-speed bicycles that can achieve multi-stage speed change, that is, the variable-speed bicycle allows the rider to choose the appropriate gear ratio according to needs, that is, the gears of different levels when the bicycle is in motion, so as to meet the needs of the riding process. various road conditions encountered. [0004] However, the variable-speed bicycles with different gears are still step-shifted in nature, that is, they can only be selected to change between fixe...
