ABSTRACT:
The articulated device for the guidance and levitation of a rail vehicle is composed of a deformable support equipped with at least four independent wheels and comprising a horizontal crossmember and two longitudinal members pivotable and tiltable relative to the crossmember. The two longitudinal members, each equipped with at least two wheels and mounted longitudinally on articulated elements, carry the crossmember on either side of the longitudinal vertical plane of the vehicle, so as to be directionally pivotable in a horizontal plane and, on the other hand, tiltable in a vertical plane in order to make it possible for the wheels carried by the longitudinal members connected to one another by means of a link and ball-mounted to follow the curves of the track and pass over the inequalities of the latter. According to the invention, the crossmember, at its ends, carries pivots for the articulation of longitudinal members, having variable relative positions. This results in a compensation of the loss of distance between the longitudinal members, occurring during this rotation, and therefore a constant matching between the spacing of the wheels and the width of the track.
