Abstract

A hub assembly comprises a hub axle, a hub shell, a sprocket support body, a first ratchet member, a second ratchet member, and a spacer. The spacer includes at least one base member and at least one axial projection. The at least one axial projection extends from the at least one base member in an axial direction. The at least one axial projection is at least partially provided between at least one first tooth and at least one second tooth in a circumferential direction. A first axial tooth-end is closer to an axial center plane of the hub assembly than a second axial tooth-end. The at least one base member of the spacer is disposed at a location closer to the first axial tooth-end than the second axial tooth-end.

Dependent claims

A hub assembly for a human powered vehicle, the hub assembly comprising:

a hub axle having a center axis defining an axial direction and a circumferential direction;
a hub shell rotatably mounted on the hub axle to rotate about the center axis, the hub shell including at least one first tooth having a first axial tooth-end and a second axial tooth-end opposite to the first axial tooth-end;
a sprocket support body rotatably mounted on the hub axle to rotate about the center axis, the sprocket support body including a first spline;
a first ratchet member including:
at least one first ratchet tooth;
and
a second spline configured to engage with the first spline;
a second ratchet member including:
at least one second ratchet tooth configured to engage with the at least one first ratchet tooth;
and
at least one second tooth configured to engage with the at least one first tooth;
a spacer including:
at least one base member extending in the circumferential direction;
and
at least one axial projection extending from the at least one base member in the axial direction, the at least one axial projection being at least partially provided between the at least one first tooth and the at least one second tooth in the circumferential direction;
the first axial tooth-end of the at least one first tooth being closer to an axial center plane of the hub assembly than the second axial tooth-end of the at least one first tooth;
and
the at least one base member of the spacer being disposed at a location closer to the first axial tooth-end of the at least one first tooth than the second axial tooth-end of the at least one first tooth.
