US 10,293,639 B2 · Bicycle hub assembly

Abstract

A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, a first ratchet member, a second ratchet member, and a sliding member. The hub shell includes at least one first tooth. The sprocket support body includes a first helical spline. The first ratchet member comprises at least one first ratchet tooth and a second helical spline engaged with the first helical spline. The second ratchet member comprises at least one second ratchet tooth and at least one second tooth. The at least one second ratchet tooth is engageable with the at least one first ratchet tooth. The at least one second tooth is engaged with the at least one first tooth. The sliding member is provided between the sprocket support body and the second ratchet member in an axial direction parallel to a rotational axis. The sliding member includes a non-metallic material.
