Abstract (en)
[origin: EP0348378A1] A device consisting of a deformable support equipped with at least four independent wheels (5, 55 and 45, 65) and comprising a horizontal transom (3) and two sole bars (4, 44) which pivot and can be inclined relative to the transom (3). <??>The two sole bars (4, 44), each provided with at least two wheels (5, 55 and 45, 65), are mounted on articulated elements (7, 47) fixed to the transom (3) on either side of the longitudinal axial vertical plane of the vehicle, such that the articulation pivots (for example 18, 38, 52, 91) of the sole bars (4, 44) have variable relative positions. This results in a compensation of the reduction in distance between sole bars (4, 44) which occurs when they pivot, and hence a constant good match between the spacing of the wheels (5, 45, 55, 65) and the width of the track.
