[0041] The best way to implement the present invention will be explained in detail according to the drawings. Several pairs of driving wheels (27) are connected to the input spline shaft (28), and the outer disk springs (26) clamp the planet wheels (24). The spring (23) and the outer pressing ring (30) also press against the radial periphery of the planetary gear (24). When the input spline shaft (28) drives the driving wheel (27) and the planetary gear (24), due to the outer pressing ring (30) Clamped by the deformed elastic force of the outer disc spring (23), the planetary gears (24) are rotated and rotated, and each planetary gear (24) pushes the shaft (6), the sliding block (4) and the turntable (3). ) And crankset (15) output torque.
[0042] After the control lever (29) and the intermediate clutch (9) are combined with the grooved gear ① or gear ②, they are transmitted through the corresponding chainring gear ① or chainring gear ②, because the number of teeth of the releva...
