<p>An internal transmission hub assembly (12) includes a shift control sleeve (16), a sleeve guide (22) and a shifting key guide (24). The shift control sleeve (16) is disposed for limited circumferential movement about the axis of rotation of a stationary hub shaft. The shift control sleeve (16) includes a base sleeve (100) and at least one pawl control arm, the base sleeve (100) having a first end (108) and a second end (110). The sleeve guide (22) supports the first end (108) of the base sleeve (100) of the shift control sleeve (16) about the stationary hub shaft. The first end of the base sleeve is welded to the sleeve guide. The shifting key guide (24) supports the second end (110) of the base sleeve (100) of the shift control sleeve (16) about the stationary hub shaft. The second end (110) of the base sleeve (100) is welded to the shifting key guide (24).</p> |
