REAR WHEEL AXLE, AS WELL AS BICYCLE FRAME AND REAR WHEEL FOR A BICYCLE

摘要

A rear wheel axle for a bicycle includes a hollow wheel axle and an axle shaft inserted therethrough and torque support elements for supporting torque exerted on the wheel axle on drop outs of a bicycle frame. The torque support elements are formed by a first part of an outside of the axle shaft and a part of an inside of the wheel axle, which parts jointly form a first form locked connection, and are also formed by a second part of the outside of the axle shaft, which together with a bounding wall of a through hole provided in an inserted piece which is fixed in the direction of rotation relative to one of the drop outs, forms a second form locked connection. The first and second parts of the outside of the axle shaft are fixed relative to each other in the direction of rotation of the axle shaft.
