| 摘要 |
The invention relates to a road-rail vehicle (1), in particular a road-rail heavy goods vehicle, comprising a drive device (4) for operating on rails, said device having a rail driving wheel (10), in addition to a friction drum (20) that is coupled to the rail driving wheel (10) via a gear (12, 16). In order to drive the vehicle (2) during an operation on rails, said drum can be placed against the peripheral surface of a road driving wheel (22) of the road-rail vehicle (1) by an actuating device (24), moving from a first operating position for roads into a second operating position for rails. The road-rail vehicle is characterised in that the gear contains a mechanical reversing gear (12), which, for a predetermined rotational direction of the road driving wheel (22), permits a reversal of the rotational direction of the rail driving wheel (10) to achieve the forward or reverse travel of the vehicle (1). |
