Abstract
A hub assembly comprises a hub axle, a hub shell, a sprocket support body, a first bearing unit, a second bearing unit, and a sleeve. The sleeve includes a first abutment portion and a second abutment portion. The first abutment portion abuts the first inner race. The second abutment portion abuts the second inner race in a radial direction.
Claims19
A hub assembly for a human powered vehicle, the hub assembly comprising:
- a hub axle having a center axis defining an axial direction, a radial direction and a circumferential direction;
- a hub shell rotatably mounted on the hub axle to rotate about the center axis;
- a sprocket support body rotatably mounted on the hub axle to rotate about the center axis, the sprocket support body being configured to support at least one sprocket;
- a first bearing unit disposed between the hub axle and the hub shell in the radial direction;
- a second bearing unit disposed between the hub axle and the sprocket support body in the radial direction;
- a sleeve mounted on the hub axle and extending in the axial direction, the sleeve being contactable with the hub axle in the radial direction;
- the first bearing unit including:
- a first inner race coupled to the hub axle;
- a first outer race coupled to the hub shell;
- and
- at least two first rolling members disposed between the first inner race and the first outer race in the radial direction;
- the second bearing unit including:
- a second inner race coupled to the hub axle;
- a second outer race coupled to the sprocket support body;
- and
- at least two second rolling members disposed between the second inner race and the second outer race in the radial direction;
- and
- the sleeve including:
- a first abutment portion abutting the first inner race;
- and
- a second abutment portion abutting the second inner race in the radial direction.
