Abstract

A bicycle hub with an axle, a shell, a rotor with a rotor body and a freewheel device with, a hub-side toothed disk device coupled to the hub shell, and a rotor-side toothed disk device interacting therewith and coupled to the rotor body, to drivingly couple the rotor to the hub shell in the driving direction and decouple from one another when freewheeling. The toothed disk devices include an end toothing and are biased to an engagement position. A sprocket accommodation is on the rotor body which includes on the hub-side end an inner radial wall to support a hub-side rotor bearing. On an end face at the hub-side end of the rotor, radially between the inner radial wall and an rotor outer wall, a circumferential accommodation accessible from the end face is configured, so the rotor-side toothed disk device is accommodated in a fixed driving manner and axially movable.

Claims19

Dependent claims

A hub for at least partially muscle-powered vehicles, comprising:

a hub axle;
a hub shell;
a rotor with a rotor body;
and a freewheel device with two toothed disk devices, one hub-side toothed disk device coupled to the hub shell, and one rotor-side toothed disk device interacting therewith and coupled to the rotor body, to couple the rotor to the hub shell in a rotationally fixed manner in the driving direction, and to decouple them from one another in a freewheeling position;
wherein each of the toothed disk devices comprises an end toothing for engagement with one another, and is biased by means of at least one biasing device to an engagement position;
wherein at least one sprocket accommodation for at least one sprocket device is configured outwardly on the rotor body;
and wherein the rotor body comprises on the hub-side end, an inner radial wall to radially support a hub-side rotor bearing;
on an end face at the hub-side end of the rotor, radially between the inner radial wall and an outer wall of the rotor, a circumferential accommodation accessible from the end face is configured, in which the rotor-side toothed disk device is accommodated in a rotationally fixed manner in the driving direction and axially movable.

5 more elements

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

a rotor body, extending from an inner, hub-side end toward an outer end, and comprising a rotor-side toothed disk device coupled to the rotor body, to couple the rotor body to a hub shell in a rotationally fixed manner in the driving direction, and to decouple from the hub shell in a freewheeling position (F);
wherein the rotor-side toothed disk device comprises an end toothing for engagement with an end toothing coupled to a hub shell, and wherein the rotor-side toothed disk device is biased to an engagement position (E) by means of at least one biasing device;
wherein at least one sprocket accommodation for at least one sprocket device is configured outwardly on the rotor body, and wherein the rotor body comprises on the hub-side end, an inner radial wall to radially support a hub-side rotor bearing;
and
on an end face on the hub-side end of the rotor, radially between the inner radial wall and the outer wall, a circumferential accommodation accessible from the end face is configured, in which the rotor-side toothed disk device is accommodated in a rotationally fixed manner in the driving direction and axially movable.
