Embodiment
[0041] The present embodiment is described with the ten-speed internal transmission of bicycle, see Figure 1 to Figure 5 , The internal transmission of this embodiment includes a main shaft 1 , a power input assembly, a power transmission assembly, a gear control assembly and an output hub 8 .
[0042] The power input assembly includes a flywheel 7, a flywheel seat 6, and a flywheel retainer. The flywheel 7 is fastened on the flywheel seat 6, and the bicycle power drives the flywheel seat 6 to rotate through the flywheel 7. The power input assembly inputs bicycle power through the flywheel 7 and transmits it to the power transmission assembly through the flywheel seat 6;
[0043] The power transmission assembly of the internal ten-speed transmission consists of three sets of double-row planetary gear trains, including two planetary carriers, three sets of double planetary gears, five sun gears, three one-way clutches, two ring gears, and planetary gear trains The input end is ...
