<p>The self-centered wheel comprises a spring and a wheel rim (1), which is connected with a bushing (2) of the wheel by a flexible cable (3a,3b), and is supported on a bearing (4) fixed on the wheel rim and on the bushing. The spring serves for the tension of the flexible cable and the improvements of the amortization characteristics of the wheel. The bushing is filled by two of the halves movable along the rotational axis of the wheel, and the spring is positioned between the halves.</p> |
