A multi-layer pinion assembly for a rear wheel assembly of a bicycle having a chained shift includes a multi-layer pinion arrangement and a screw plug arrangement. The multi-layer pinion arrangement is adapted to be coupled in a torque-transmitting manner with a transmission of the rear wheel assembly and includes at least 11 pinions of different numbers of teeth. The multi-layer pinion assembly is constructed in such a way that, after completion of installation, at least two of the smallest pinions are axially secured to the transmission by means of the screw plug arrangement. The screw plug is provided with a rod section for accommodating at least one of the at least two minimum pinions, the rod section is provided with an axial outer stop section on one end region of the rod section, and the rod section is provided with at least one outer thread on the opposite end region of the rod section; the screw plug arrangement may be screwed into a corresponding internal thread by means of the external thread to secure the screw plug arrangement. The external thread assigned to the rod section has an outer diameter which is greater than the outer diameter of the rod section in a region in which at least one of the at least two smallest pinions is accommodated.

    一种用于具有链式换挡装置的自行车的后轮组件的多层小齿轮组件包括多层小齿轮配置和螺旋塞配置。所述多层小齿轮配置适于与所述后轮组件的传动装置以传递转矩的方式耦合,且包括齿数不同的至少11个小齿轮。所述多层小齿轮组件以某种方式构建,使得在安装完毕后,所述最小的小齿轮中的至少两个通过所述螺旋塞配置轴向固定在所述传动装置上。所述螺旋塞配置具有用于容置所述至少两个最小的小齿轮中的至少一个的杆段,其中所述杆段在其一个端区上配设有轴向外止挡区段,且其中所述杆段在其相反的端区上分配有至少一个外螺纹,所述螺旋塞配置可以借助于所述外螺纹旋入对应的内螺纹以固定所述螺旋塞配置。分配给所述杆段的外螺纹具有外径,所述外径大于所述杆段在容置有所述至少两个最小的小齿轮中的至少一个的区域内的外径。
