A bogie comprises two wheel pairs (11, 12). Each wheel pair is mounted for pivotal or tiltable movement on a shaft (13) which extends at right angles to the axle direction (111, 121) of respective wheel pairs, with a total pivot angle of about 30 DEG . The wheel pairs together are mounted for rotation on a second shaft (14) which extends at right angles to the first-mentioned shaft (13). A combined bogie includes two sub-bogeys (400, 410), each of which comprises two mutally identical units each having two (21, 22; 21', 22') or four (31, 32, 31', 32'; 33, 34, 33', 34') wheel pairs. One sub-bogie (400) is fitted to a power unit (40) and one sub-bogie (410) is fitted to a loader (41). The power unit and the loader are pivotal in relation to one another about an axis (y-y) which extends at right angles to the axle directions of respective wheel pairs, and also about an axis (x-x) which extends parallel to the axle directions of the respective wheel pairs. The angle ( alpha ) between longitudinal directions (401, 411) on the upper sides of respective sub-bogeys is always >/= 180 DEG . |
