Abstract
On a multispeed bicycle wheel hub with a sun and planet gear mechanism having at least two multistage planet wheels, the planet wheels are each constructed of two parts, with a first planet wheel part having a rolling gearing segment forming one planet wheel stage and a clutch gearing segment having a clutch outside circumference gearing, as well as a second planet wheel part having at least one rolling gearing segment, each forming a planet wheel stage, as well as a receptacle opening for the clutch gearing segment of the first planet wheel part, which receptacle opening is equipped with a clutch inside circumference gearing which is engaged in the clutch outside circumference gearing. The second planet wheel part is formed by a sintered part, and the first planet wheel part is formed by a machined part, whereby the clutch outside circumference gearing has the same number of teeth and gear rim orientation as the clutch outside circumference gearing. The invention makes it possible to achieve an precisely specified mutual orientation of the planet wheel stages with low manufacturing costs.
