Hub for a bicycle
A hub with a hub body, the hub body having two end units and a tubular center part, and the center part being disposed between, and received at, the end units. At least one end unit includes a tubular inserting portion onto which the center part having a tubular slip-on portion is pushed. The inserting portion and the slip-on portion overlap in an overlapping region.
1. A hub comprising:
a hub body;
the hub body including two end units and at least one center part;
the center part is disposed between and received at the end units; and
at least one end unit comprises a tubular inserting portion onto which the center part comprising a tubular slip-on portion is pushed, wherein the inserting portion and the slip-on portion overlap in an overlapping region and a guiding portion and a gluing portion are provided in the overlapping region,
wherein the guiding portion is provided with a diameter tolerance that is lower between the inserting portion and the slip-on portion than at the gluing portion.
2. The hub according to claim 1 wherein the inserting portion has stepped outer diameters at the overlapping region and wherein the slip-on portion has a constant inner diameter.
3. The hub according to claim 1 wherein the inserting portion and the slip-on portion are round in cross-section.
4. The hub according to claim 2 wherein a diameter difference between an inner diameter of the slip-on portion and an outer diameter of the inserting portion in the gluing portion is between 0.2% and 1.5% of the inner diameter of the slip-on portion.
5. The hub according to claim 1 wherein an axial width of the guiding portion is smaller than an axial width of the gluing portion.
6. The hub according to claim 1 wherein the center part consists at least in part of at least one fibrous composite material.
7. The hub according to claim 1 wherein the guiding portion is disposed at an axial end of the overlapping region.
8. The hub according to claim 1 wherein the guiding portion is provided at an axial end of the center part.
9. The hub according to claim 1 wherein the guiding portion is provided axially farther outwardly than the gluing portion.
10. The hub according to claim 1 wherein the slip-on portion has stepped inner diameters at the overlapping region and wherein the inserting portion has a constant outer diameter.
11. A hub comprising:
a hub body;
the hub body including two end units and at least one center part;
the center part is disposed between and received at the end units;
at least one end unit comprises a tubular inserting portion onto which the center part comprising a tubular slip-on portion is pushed, wherein the inserting portion and the slip-on portion overlap in an overlapping region and a guiding portion and a gluing portion are provided in the overlapping region; and
at least one metallic sleeve received at the center part.
