Two-part hubs for torsional vibration dampers are disclosed that have a main body made of a softer material than a seal nose and do not require a welded joint to join them together. The main body has a plate defining a front face and a back face, an annular core extending axially outward from the back face of the plate and defining an innermost, outer radial surface and a first bore through the main body, and an outermost, radial, elastomer- receiving surface spaced apart from the innermost outer radial surface by the plate. The seal nose is mated to the innermost, outer radial surface of the annular core and mechanically engaged with the main body for rotation together. Torsional vibration dampers that include the two-part hubs are also disclosed, as well as a front end accessory drive including the same, and methods of manufacturing the two-part hubs. |
