A vehicle-driving wheel bogie comprises two wheels (9, 10) with tread-designed tyres, each one of which being mounted in bearings on a wheel-carrying part which is pivotable via a joint relative to a frame body (11), the wheels of the bogies being drivable in either of two opposed directions of rotation by means of a hydraulic motor. A hydraulic motor serves as the permanent and sole driving mechanism for the pairs of wheels (9, 10) of the individual bogie, which motor is placed in the region between the tyres of the wheels and has its output shaft connected to a driving roller (24) with a plurality of peripherically separate carrier elements which are in a driving engagement with the surface design of each one of the wheel tyres. The hydraulic motor and the driving roller (24) are mounted in the region of an upper end of a substantially vertically positioned, pivotable holding arm, which in the region of its lower end is articulately connected to said frame body (11) in a joint located at a level below the centres of rotation of the wheels (9, 10). |
