摘要： A shift assist projection is provided on a large bicycle sprocket to assist in shifting a chain to the sprocket from an adjacent smaller sprocket. The shift assist projection extends axially from one side of the sprocket. The shift assist projection has an axially facing chain catching surface that faces the center plane and the teeth of the large sprocket to engage an outer link plate of the chain. The chain catching surface is preferably angled a varying amount relative to the center plane of the large sprocket. The chain catching surface preferably has a rearward most rotational edge that is located closer to the center plane than a forward most rotational edge as viewed substantially along a moving direction of the chain when the chain is being shifted from the smaller sprocket to the large sprocket.
摘要翻译：在大型自行车链轮上设置换档辅助突起，以帮助从相邻的较小链轮将链条移动到链轮。换档辅助突起从链轮的一侧轴向延伸。换挡辅助突起具有面向中心平面的轴向面向的链条捕捉表面和大链轮的齿以与链条的外链板接合。链条捕捉表面优选地相对于大链轮的中心平面具有不同的量。当链条从较小的链轮移动到大的链轮时，链条捕获表面优选地具有最靠后的最大旋转边缘，该后端大致沿着链条的移动方向观察到比最前面的旋转边缘更靠近中心平面。

摘要： A bicycle front derailleur includes a chain guide that is provided with a pushing element that is movable relative to the chain guide to assist in shifting a bicycle chain from a smaller front sprocket to an adjacent larger sprocket. The chain guide is part of a movable member that is movably coupled to a base member via a linkage assembly. The pushing element is rotatably coupled to the chain guide portion and activated by a chain to move relative to the inner chain guide member from a first position with the pushing element at rest to a second position in response to activation by the chain. The contact surface moves laterally outwardly into the chain receiving slot toward the outer chain guide member as the pushing element moves from the first position to the second position.
