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 1

[0072] Such as figure 1 As shown, the method for realizing the stepless speed change of a bicycle in the first embodiment is used for a bicycle with a speed governor, and includes the following steps:

[0073] Step 1, installing a speed change body with a speed change bracket in the hub of the bicycle;

[0074] Step 2: Place the input tapered rotor and the output tapered rotor opposite to each other on the transmission bracket, and make the input tapered rotor and the output tapered rotor reversed so that the tapered surface of the input tapered rotor and the tapered output rotor form a Parallel sliding tracks; wherein, both the input tapered rotor and the output tapered rotor are in the shape of a cone with a small end and a large end;

[0075] Step 3, placing a sliding component capable of simultaneously touching the input tapered rotor cone surface and the output tapered rotor cone surface on the formed sliding track, so that the sliding component can slide on the sliding ...

Embodiment 2

[0082] Such as Figure 2 to Figure 27 As shown, in the second embodiment, the continuously variable transmission structure for realizing the continuously variable transmission of the bicycle includes a hub 1 for connecting spokes, a hub cover 2, a hub ring gear 3, a transmission body 4, an input disc 5, and at least three An input tapered rotor 6, an output tapered rotor 7, and a main shaft 8; the hub 1 is tightly fitted with the hub cover 2; the tightly fitted hub 1 and the hub cover 2 form a sealed shell, thereby sealing and supporting the transmission body 4 function, which can also prevent the entry of mud and sand during riding, making the riding process safer and smoother, and prolonging the service life of the continuously variable transmission structure; among them:

[0083] The transmission body 4 has a first cavity 40 with both ends open, at least three first struts 41 and at least three second struts 42; each first strut 41 and each second strut 42 together play the...

Abstract

The invention relates to a method of achieving infinitely variable speeds for a bike and an infinitely variable speeds structure. The method includes the steps that a variable speed body with variablespeed supports are installed in a hub of the bike; an input taper rotor and an output taper rotor which can rotate are placed on the corresponding variable speed supports, and the input taper rotor and the output taper rotor are oppositely placed in an inverted mode to enable a taper surface of the input taper rotor and the taper surface of the output taper rotor to form a horizontal sliding rail; sliding parts which can simultaneously abut against the taper surfaces of the input taper rotor and the output taper rotor are placed on the sliding rail, so that the sliding parts can slide on thesliding rail; the input taper rotor is indirectly rotated through the control of a speed controller of the bike, and further to drive the sliding parts to rotate on the sliding rail; the sliding partsabut against the input taper rotor to enable the input taper rotor to rotate; and the input taper rotor indirectly drives a hub tooth ring to rotate, and the infinitely variable speeds of the bike through the speed controller can be achieved.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to a method for realizing stepless speed change of a bicycle and a structure for stepless speed change. 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...
