Abstract
A motor driven derailleur includes a base member; a movable member; and a linkage mechanism including a link member coupled to the base member and to the movable member so that the movable member moves relative to the base member, wherein the link member is pivotably coupled to one of the base member and the movable member through a first link coupling member. A motor is provided for rotating the first link coupling member, wherein the movable member moves relative to the base member in response to rotation of the first link coupling member.
Claims26
A derailleur comprising:
- a base member;
- a movable member;
- a linkage mechanism including a link member coupled to the base member and to the movable member so that the movable member moves relative to the base member, wherein the link member is pivotably coupled to one of the base member and the movable member through a first link coupling member;
- a motor having a motor shaft disposed at least in part between side edges of the link member for rotating the first link coupling member relative to the one of the base member and the movable member that the link coupling member couples the link to;
- and
- wherein the movable member moves relative to the base member in response to rotation of the first link coupling member.
