<p>A wheel hub unit (1), particularly for a motor vehicle, comprises a hub (2) having a centring sleeve portion (3) axially projecting from a radial side surface (10) of the hub and defining an inner through bore (4), an axle (5) rotatably supporting the hub (2), a wheel (6) with a radially inner annular rim (7) defining a centring bore (8) for fitting onto the hub sleeve portion (3), and a cover (9) for closing the through bore (4). The cover (9) is forcefully fitted over a radially outer surface (15) of the hub sleeve portion (3) such that a cylindrical portion (21) of the cover (9) is interposed between the annular rim (7) of the wheel (6) and the radially outer surface (15) of the hub sleeve portion (3). <IMAGE></p> |
