Multi-stage planetary gearbox for a bicycle or pedelec

Abstract

Multi-stage planetary gear unit for a bicycle or pedelec, with a gear input shaft (1) as the drive and a gear output shaft (2) as the output, with at least three planetary gear sets (RS1, RS2, RS3, VRS, NRS), wherein at least three freewheel clutches (F1, F2, F3, FV, FN) and at least three brakes (B1, B2, B3, BV, BN) are provided to realize at least eight gears (G1, G2, G3, G4, G5, G6, G7, G8, G9, G10, G11, G12, G13, G14, G15, G16), wherein a second element of the first planetary gear set (RS1) is connected as an input element directly or via at least one further element to the gear input shaft (1), wherein a first element of the first planetary gear set (RS1) is connected as an output element directly or via at least one further element to the gear output shaft (2), wherein a third element of the first planetary gear set (RS1) is connected as a coupling element to a second element of the second planetary gear set (RS2),wherein a first element of the second planetary gear set (RS2) can be locked via a first brake (B1), wherein the first element of the second planetary gear set (RS2) can be connected to the second element of the first planetary gear set (RS1) via a first freewheel clutch (F1), wherein a third element of the second planetary gear set (RS2) is connected to a second element of a third planetary gear set (RS3), wherein a first element of the third planetary gear set (RS3) can be locked via a second brake (B2), wherein the first element of the third planetary gear set (RS3) can be connected to the first element of the first planetary gear set (RS1) via a second freewheel clutch (F2), wherein a third element of the third planetary gear set (RS3) can be connected to the first element of the first planetary gear set (RS1) via a third freewheel clutch (F3), and wherein the third element of the third planetary gear set (RS3) can be locked via a third brake (B3). is.,
