The invention relates to an arrangement for a wheelchair drive ring that is separate from the wheel of the wheelchair and exhibits a drive-actuating surface (5) facing in a direction outwards from the wheelchair wheel. In accordance with the invention, an upper concave drive-actuating surface (6) of the drive ring, which can be attached separately to the rim of the wheelchai r wheel, is transformed directly into a lower convex drive-actuating surface. The aforementioned lower convex drive-actuating surface is transformed into a circular gripping part on the underside of the outward-facing drive-actuatin g surface (5). The aforementioned upper concave drive-actuating surface (6) an d the gripping part are transformed jointly into a downward-angles finger guar d extending in towards the centre of the wheel. Friction-increasing gripping material (100) is provided only on the upper concave drive-actuating surface (6) of the drive ring.
