Hub, in particular for bicycles

A hub for at least partially muscle-powered vehicles, comprising a hub axle;

• a hub shell;
• a rotor;
• and a freewheel device,
• wherein the hub shell is supported for rotation with at least two axially spaced apart hub bearings, namely, at least one rotor-side hub bearing disposed closer to the rotor and at least one outer hub bearing further distant from the rotor;
• and wherein the rotor is supported for rotation with at least two axially spaced apart rotor bearings, namely, one hub-side rotor bearing disposed closer to the hub shell and at least one outer rotor bearing further distant from the hub shell;
• and wherein the freewheel device comprises a hub-side toothed disk device coupled with the hub shell, and a rotor-side toothed disk device interacting therewith and coupled with the rotor, each comprising an end toothing to engage with one another, and biased to an engagement position by means of at least one biasing device, wherein the end toothing of the hub-side toothed disk device is axially oriented to the rotor;
• and wherein the rotor-side toothed disk device is accommodated radially within the rotor, and by way of an outer radial toothing with an inner radial toothing in the rotor is coupled with the rotor in a rotationally fixed manner in the driving direction, and wherein the end toothing of the rotor-side toothed disk device is axially oriented to the hub shell;
• wherein a clear inner diameter of the rotor-side toothed disk device is larger than an outer diameter of the hub-side rotor bearing;
• wherein at least one hub bearing and at least one rotor bearing are configured as a roller bearing, each provided with a plurality of rolling members;
• wherein a central plane of cross section through the rotor-side toothed disk device intersects the rolling members of the hub-side rotor bearing;
• wherein a central plane of cross section through the hub-side toothed disk device intersects the rolling members of the rotor-side hub bearing;
• and
• wherein the axial distance of the central plane of cross section through the rotor-side toothed disk device, from the plane of cross section through the rolling members of the hub-side rotor bearing, is smaller than a diameter or a radius of a rolling member.
