| 摘要 | A vehicle of the sledge or bobsleigh type is provided in its lower part with idle wheels or rollers for descending slopes. A first set of inner rollers (22-29) is positioned in the proximity of a longitudinal midline (x) of the vehicle (10); a second set of right-hand outer rollers (40-43) is positioned along a right-hand side of the vehicle, and is higher than the first set of inner rollers (22-29); a third set of left-hand outer rollers (44-47) is positioned along a left-hand side of the vehicle so as to be symmetrical to the second set of right-hand outer rollers (40-43). The rollers of the second (40-43) and third (44-47) set are mounted on respective rotation axles (30-33; 34-37), where - the axles (30-33) of the second set of right-hand outer rollers (40-43) lie on an oblique plane (P1) inclined outwards to the right and upwards, and converge towards a point (C1) located outside the right-hand side of the vehicle, and - the axles (34-37) of the third set of left-hand outer rolling elements (44-47) lie on an oblique plane (P2) inclined outwards to the left and upwards, and converge towards a point (C2) located outside the left-hand side of the vehicle. |
