Embodiment Construction

[0018] The following is a specific embodiment to further illustrate the present invention. It should be understood that this embodiment is only used to illustrate the present invention and is not intended to limit the scope of the present invention. After reading the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0019] Such as figure 1 A transmission structure is shown, including the transmission structure including an output cam 1 , a cage assembly 2 , a traction ring 3 , a steel ball assembly 4 and an input cam 5 . The steel ball assembly 4 includes a nut, a pin shaft and a steel ball. Threads are provided at both ends of the pin shaft, and the steel ball is axially fixed by the nut. The steel ball can rotate along the pin shaft. Six steel ball assemblies are arranged in pairs. Such as Figure 5 The shown cage ...

Abstract

The invention discloses a transmission structure. The transmission structure comprises an output cam, retainer assemblies, pulling rings, steel ball assemblies and an input cam. The pulling rings, theretainer assemblies as well as the input cam and the output cam are symmetrically disposed on the two sides of the steel ball assemblies. The input cam rotates to drive rollers of one retainer assembly to rotate, then the rollers drive one pulling ring to rotate, the other side of the pulling ring makes contact with steel balls in the planetary positions, the pulling ring drives the steel balls to perform autorotation, the steel balls perform autorotation to drive the other pulling ring at the output end to rotate, the other pulling ring drives the other retainer assembly and the output cam to rotate, and therefore the transmission effect is achieved. The transmission structure is mainly applied to a continuously variable transmission of a bicycle, and is steady in transmission, free of pause and transition and capable of achieving one-way transmission so as to prevent backward sliding during upslope riding.

Description

technical field [0001] The invention relates to a transmission structure, in particular to a friction transmission structure. Background technique [0002] The transmission devices of bicycles and electric vehicles generally adopt chain transmission, which has the advantages of high reliability and simple transmission structure. Most of the popular bicycles in recent years have the function of gear shifting, which is convenient to adapt to the power transmission needs of riders of different ages and different road conditions. The more high-end bicycles have more gears. [0003] However, for the chain drive, the impact load is large during the transmission process, and it is easy to generate noise under the condition of insufficient lubrication for shifting and shifting through the chain drive, and it will cause frustration and affect the riding experience. phenomenon, causing safety hazards. Contents of the invention [0004] Purpose of the invention: In view of the abov...
