The drive wheel is mounted on a rocker arm on the chassis, and the arm may also carry a drive motor for the wheel. Each wheel has more than one bearing blocks, and one axle journal is associated with at least one rocker arm and one bearing block. Each axle journal is fastened in a bearing block axially and radially elastic, and with suspension effect. The space between the axle journal (7) an the bore in the bearing block (5) is filled with an elastic element (6), e.g. a sleeve. The sleeve is of rubber or thermoplastic elastomer. |
