ABSTRACT OF THE DISCLOSURE The present invention provides in a track vehicle with swivelling track, a track mat, of which one side may be lengthened and the other side correspondingly shortened by turning at least one end roll guiding the track mat, to bring the track mat into a curved position causing the vehicle to turn, said track mat having a central band or equivalent, extending parallel to the direction of travel of the vehicle and bendable to assume a cur- vature substantially determined by the turning radius of the vehicle and which is substantially unextendable in its longitudinal direction, said track mat when straight and substantially parallel to the direction of travel of the vehicle, having in marginal areas thereof an internal pre-stressed condition, which tends to contract the track mat in said marginal areas, and when curved the internal stress of the track mat is inferior, on the side of the inner turn of the track mat to said internal pre-stress and on the outer turn side of the track mat the internal stress of the track mat is superior to said internal pre-stress.
