Abstract
A hub for a bicycle wheel having a hub body rotationally mounted on a central hollow shaft by means of bearings mounted on the shaft, the hollow shaft adapted to receive a quick release axle which projects beyond both ends of the axle. The shaft has three distinct portions, two end pieces and a central portion made of a material having a lower density than the end pieces, the end pieces being fitted to each end of the central portion, the end pieces having bearing surfaces for the bearings, and at least one of the end pieces having a threaded portion, respectively, for a nut for axially tightening the bearings.
Claims19
A hub assembly for a bicycle wheel, the hub assembly comprising:
- a hollow shaft adapted to receive a quick-release axle and extending along a longitudinal axis, said hollow shaft comprising the following three distinct portions:
- a central portion having a first end and a second end;
- a first end piece mounted to the first end of the central portion of the hollow shaft and extending longitudinally beyond the first end of the central portion of the hollow shaft;
- a first shouldered nipple extending longitudinally from the first end piece of the hollow shaft and adapted to be secured to a first part of a bicycle fork;
- a second end piece mounted to the second end of the central portion of the hollow shaft and extending longitudinally beyond the second end of the central portion of the hollow shaft;
- a second shouldered nipple extending longitudinally from the second end of the hollow shaft and adapted to be secured to a second part of a bicycle fork;
- said central portion forming a spacer between said first and second end pieces;
- said central portion being made of a material having a lower density than a material of either of the first and second end pieces;
- a hub body;
- a first bearing and a second bearing, each of said first and second bearings comprising an inner race and an outer race, said inner races of said first and second bearings being mounted on said first and second end pieces of said central portion of said hollow shaft, and said outer races of said first and second bearings being mounted to the hub body for rotationally mounting the hub body to the hollow shaft.
A hub assembly for a bicycle wheel, the hub assembly comprising:
- a central hollow shaft comprising a cylindrical tube extending longitudinally along a longitudinal axis, said hollow shaft having a first end and a second end, said central hollow shaft adapted to receive a quick-release axle, said central hollow shaft comprising the following three distinct portions:
- a first end piece mounted to the first end of the central hollow shaft, the first end piece extending longitudinally beyond the first end of the hollow shaft;
- a second end piece mounted to the second end of the central hollow shaft, the second end piece extending longitudinally beyond the second end of the hollow shaft;
- a central portion forming a spacer between said first and second end pieces, the central portion being made of a material having a lower density than a material of either of the first and second end pieces;
- a hub body;
- a first bearing and a second bearing, each of said first and second bearings comprising an inner race and an outer race, said inner races of said first and second bearings being mounted on said first and second end pieces of said central hollow shaft, and said outer races of said first and second bearings being mounted to the hub body for rotationally mounting the hub body to the central hollow shaft;
- a first shouldered nipple mounted on the first end of the central hollow shaft, and a second shouldered nipple mounted on the second end of the central hollow shaft, said first and second shouldered nipples being adapted to be secured to respective parts of a bicycle fork.
