Abstract
The invention is directed to a hub unit of a fan wheel for an internal combustion engine having a crankshaft and a starter device. The hub unit has a wheel body made of plastic and a hub sleeve made of a high tensile strength material. The hub sleeve carries the wheel body and is held on the crankshaft to prevent rotation relative thereto and a clamping element axially fixes the hub sleeve on the crankshaft. A starter ring is concentric with the axis and is adapted for a clutch engagement with the starter device so as to be entrainable thereby. The starter ring and the hub sleeve are originally formed as a single piece to define a hub housing.
