Vibration isolating engine cooling fan

摘要

An axial fan assembly includes a hub, a plurality of connection structures, and a plurality of isolated members. The hub is rotatable about an axis of rotation and includes a radially extending face and a cylindrical portion extending axially from the face. The face includes a radially inner face portion and a radially outer face portion. The plurality of connection structures extends radially inwardly from the radially outer face portion and extends radially outward from the radially inner face portion. The plurality of isolated members extends radially outwardly from the radially inner face portion and is isolated from the plurality of connection structures and from the radially outer face portion by a plurality of slots.
