Document Type and Number:
WIPO Patent Application WO/2018/126761
Kind Code:
A1
Abstract:
Disclosed are an inner derailleur and a control method therefor. A planetary gear train is used as a transmission device. A flywheel seat (11) of the inner derailleur is connected to a planetary carrier (21) of the planetary gear train by a clutch (4). Meanwhile, the flywheel seat (11) is connected to an inner gear ring (22) by an overrunning clutch component (5). The planetary carrier (21) is connected to a hub (31) of the inner derailleur by a second one-way transmission member (313). The inner gear ring (22) of the planetary gear train is connected to the hub (31) by the overrunning clutch component (5). A two-way centre wheel clutch control component (6) is arranged between a centre wheel (23) of the planetary gear train and an axle (9). The clutch (4) and the two-way centre wheel clutch control component (6) are connected by a control mechanism (7) of the inner derailleur. According to the inner derailleur, the structure of the inner derailleur is effectively simplified, so the inner derailleur can be smaller, facilitating a bicycle assembled with the inner derailleur to further realise light weight. Moreover, the inner derailleur is more convenient to operate as well as assemble and disassemble.
