Abstract:
A shift control apparatus for a hub transmission comprising:an axle defining an axle axis; a first rotating member rotatably supported around the axle axis, wherein the first rotating member includes a location for coupling to a shift control mechanism; a second rotating member rotatably supported around the axle axis; a first spring coupled between the first rotating member and the second rotating member for biasing the first rotating member and the second rotating member in a predetermined rotational direction relative to each other; a pawl support rotating member rotatably supported around the axle axis, wherein the second rotating member is disposed between the first rotating member and the pawl support rotating member; a pawl rotatably supported to the pawl support rotating member; a biasing mechanism for biasing the pawl in a radial direction; a first coupling member coupling the first rotating member to the pawl support rotating member; a pawl control rotating member for controlling a radial position of the pawl; an actuating member rotatably supported around the axle axis for rotating the first rotating member; and a second coupling member coupling the second rotating member, the pawl control rotating member and the actuating member for rotating the pawl control rotating member relative to the pawl support rotating member.
