Abstract

A multi-sprocket arrangement for a bicycle includes a larger sprocket having a passage recess on an outer link plate passage tooth on an outboard side of the larger sprocket facing a smaller sprocket. The recess is on a side of the larger sprocket facing the smaller sprocket. The passage recess extends from a radially outer tooth tip of the outer link plate passage tooth to a non-load tooth flank of the outer link plate passage tooth or a tooth base directly adjacent to the outer link plate passage tooth such that during a gear shifting of a chain from a larger sprocket to a directly adjacent smaller sprocket, the chain passes the outer link plate passage tooth on the outboard side of the sprocket.

Claims (9)

1. A sprocket for a multi-sprocket arrangement, the sprocket comprising:

a plurality of teeth, the plurality of teeth comprising at least an outer link plate passage tooth having a passage recess on an outboard side of the sprocket facing a smaller sprocket, the plurality of teeth comprising a sequence of teeth, starting from the outer link plate passage tooth in the direction of rotation, comprising an inner link plate deflecting tooth, an outer link plate engagement tooth and an inner link plate spacer tooth,

the passage recess extending from a radially outer tooth tip of the outer link plate passage tooth to a non-load tooth flank of the outer link plate passage tooth or a tooth base directly adjacent to the outer link plate passage tooth such that during a gear shifting of a chain from a larger sprocket to a directly adjacent smaller sprocket, the chain passes the outer link plate passage tooth on the outboard side of the sprocket.

2. A multi-sprocket arrangement comprising:

a smaller sprocket having a plurality of teeth; and

a larger sprocket comprising a plurality of teeth comprising at least an outer link plate passage tooth having a passage recess on an outboard side of the outer link plate passage tooth facing the smaller sprocket, the plurality of teeth of the larger sprocket comprising a sequence of teeth, starting from the outer link plate passage tooth in the direction of rotation, comprising an inner link plate deflecting tooth, an outer link plate engagement tooth and an inner link plate spacer tooth,

the passage recess extending from a radially outer tooth tip of the outer link plate passage tooth to a non-load tooth flank of the outer link plate passage tooth or a tooth base directly adjacent to the outer link plate passage tooth such that during a gear shifting of the chain from the larger sprocket to the directly adjacent smaller sprocket, the chain passes the outer link plate passage tooth on the outboard side of the sprocket, the smaller sprocket having one tooth fewer than the larger sprocket.

3. The multi-sprocket arrangement according to claim 2 , wherein starting from the outer link plate passage tooth on the larger sprocket counter to the direction of rotation, the plurality of teeth of the smaller sprocket comprises an outer link plate passage tooth that directly follows the outer link plate passage tooth on the larger sprocket.

4. The multi-sprocket arrangement according to claim 3 , wherein the plurality teeth of the smaller sprocket comprises a sequence of teeth starting from the outer link plate passage tooth of the smaller sprocket in the direction of rotation, comprising an inner link plate deflecting tooth, an outer link plate engagement tooth and an inner link plate spacer tooth.
