Abstract
The invention relates to a device at a vehicle (8) supported and driven by articulated legs (10), the legs (10) comprising a number of leg-segments (1 . . . 7) which are moveably connected to the chassis (9) of the vehicle and to each other by means of joints (11 . . . 17). The two joints located closest to the vehicle are moveable relative to each other about axes, which are perpendicular to each other.
Claims8
A vehicle (8) having a chassis (9) which is supported and driven by at least four articulated legs (10) arranged in pairs, said legs (10) comprising a number of leg-segments (1 . . . 7), which are moveably connected to said chassis (9) and to each other by means of joints (11 . . . 17), characterized in that
- each of said legs (10) has at least three joints located closest to the vehicle, these joints allowing movements about axes being successively, as seen from the vehicle, perpendicular to each other,
- the first joint (11) for movement (21) between the chassis (9) and the first leg-segment (1) has a first, substantially vertical pivot axis (11),
- the second joint (12) for movement (22) between the first leg-segment (1) and the second leg-segment (2) has a second, substantially horizontal rotational axis (12) extending along the longitudinal axis of the second leg-segment (2) and being perpendicular to the first pivot axis (11), and
- the third joint (13) for movement (23) between the second leg-segment (2) and the third leg-segment (3) has a third pivot axis (13) being perpendicular to the second rotational axis (12).
