REAR WHEEL SPROCKET ARRANGEMENT

摘要

A plurality of sprockets which are coaxial with respect to a sprocket rotation axis, are arranged with axial spacing from each other and have different numbers of teeth which are constructed for positive-locking engagement with a bicycle chain. The pinion arrangement has a gear range quotient which is formed by division of the number of teeth of the sprocket having the largest diameter by the number of teeth of the sprocket having the smallest diameter, and has a packing density quotient which is formed by division of the number of sprockets in the sprocket arrangement by the axial spacing measured in millimeters of the axially outermost pinions from each other. The pinion arrangement may have a gear range packing coefficient, formed from the product of the gear range quotient and the packing density quotient, which is greater than 1.25.

1. A bicycle rear wheel sprocket arrangement which can be rotated about a sprocket rotation axis, comprising:
a plurality of sprockets which are coaxial with respect to the sprocket rotation axis and are arranged with axial spacing from each other and have different numbers of teeth which are constructed for positive-locking engagement with a bicycle chain, the plurality of sprockets having:
a gear range quotient which is formed by division of the number of teeth of a sprocket of the plurality of sprockets having the largest diameter by the number of teeth of a sprocket of the plurality of teeth having the smallest diameter, anda packing density quotient which is formed by division of the number of sprockets in the sprocket arrangement by the axial spacing measured in millimeters of the axially outermost sprockets from each other, wherein the plurality of sprockets has a gear range packing coefficient, formed from the product of the gear range quotient and the packing density quotient, which is greater than 1.25.
