New description: [New technical field] This is a bicycle hub sleeve structure, especially a hub sleeve structure used between the wheel hub and the flywheel to withstand the flywheel transmission and synchronous rotation. By. [Prior Art] The pedaling action of the bicycle is a stepping forward for the transmission, and vice versa, and the transmission system is mainly composed of a hub, a large toothed disc, a small toothed disc, a chain, and a crank, wherein the large toothed disc is It is located on the crank portion of the bicycle, and the small toothed disc is disposed on the hub of the rear wheel, and is driven around the large and small sprocket wheels by the chain to drive, so that the vehicle body generates the advancing. In general, the bicycle transmission system is equipped with a shifting device, in which three pieces of teeth are stacked on the large toothed disc, and 5 to 1 pieces of teeth are stacked on the small toothed discs. The two ends of the chain are arranged around the tooth pieces to select different gear ratios, so that the speed change switching function can be achieved to cope with different road conditions. For the structure of the small toothed disc, it is also called "flywheel", which is embedded with the sleeve part on the hub. 'By the flywheel is rotated by the chain drive, the wheel can be driven in and out and the wheel is synchronized with the 2 Produce (4); and analyze the connection structure between the small toothed disc and the sleeve ^ is designed in such a way that the flange and the groove sleeve are embedded, and the rotational force is transmitted by the clamping area against the IX. Connected to the flywheel assembly in the rear axle part, the general structure can be roughly divided into two types. - It is Shimano (ShiinanQm is another - for Campanquero 3 M382208
