<p>The present invention relates to an arrangement (1) for a separate driving ring (2) and a driving wheel (3) for a wheel chair. In accordance with the invention, the distance (A) between the driving ring (2) and the tyre (5) on the driving wheel (3) is bridged in its entirety by an elastic flexible element (8) extending around the periphery of the driving ring (2) and the driving wheel, which element is so arranged as to exhibit a friction material such as rubber or a similar elastic material along at least a part of its extent. The aforementioned element (8) also exhibits a height (H) such that it is so arranged as to extend in a direction upwards (6) until it makes contact with the outside (7) of the driving wheel along a substantial part of its height (B).</p> |
