Gear 13

Gear Assy 1  
(not featured to provide a better overview) Gear assy one (1) is shifted 1:1 and transfers the sprocket rotation direct to the planet carrier (1-2).

Gear Assy 2
Pawl 2(2) couples sun gear 2(2) directly to the axle. The planet carrier (1-2) drives the stepped planet gears (2). With the second gear step the stepped planet gears (2) roll off the fixed sun gear 2(2). Thus one planet carrier (1-2) rotation results in 1.292 rotations of the joint ring gear (2) and sun gear (3).

Gear Assy 3
Ring gear (3) and sun gear (3) are coupled together, thus the stepped planet gears (3) cannot rotate. Gear assy (3) is therewith shifted 1:1 and transfers the rotation from gear assy (2) directly to the planet carrier (3).

One sprocket rotation results in:- 1 (Gear Assy 1) x 1.292 (Gear Assy 2) x 1 (Gear Assy 3) = 1.292 hub rotations.
