    Abstract: There is disclosed a wheel (1) that comprises a hollow central body (2), in which a coupling element (6) to be coupled to a wheel shaft (5) and to the central body (2) is present. The coupling element (6) is a coupling element that is exchangeable in dependence on the fact whether the wheel shaft (5) is a driven shaft or not. In the case of a wheel driven by the wheel shaft (5), the wheel (1) comprises a insert (6-2) as the coupling element. In the case of a wheel (1) not driven via the wheel shaft (5), comprises a shaft bearing (6-1) as the coupling element. One and the same wheel can be used in a vehicle as a driven wheel but also as a non-driven wheel, which can be realised by exchanging the coupling element (6). Furthermore the wheel can be used as a front wheel, but also as a rear wheel.
