The present invention relates to improving the stability of a turning-track track-laying vehicle such as a snowmobile. The vehicle comprises such a track belt (10), whose one edge can be stretched and whose other edge can be contracted by turning the end roll (14) or rolls (14, 15) which guide the track belt (10) so that the track belt (10) can be bent to a curved position in order to steer the vehicle. The bottom run of the track belt (10) loop is, in front of the crosswise gravity center plane (A－A) seen in the principal driving direction (E) of vehicle, pressed or weighted against the driving surface, particularly against soft snow (L－L), in such a way that, due to and in the region of said weighting, such a limited area (P33) of surface pressure higher than the average is created in which the maximum surface pressure (pmax, p2) is substantially higher than the average surface pressure (p1) in the rear section of the bottom run of the track belt.

Apparatus for improving the stability of a turning-track, track-laying vehicle such as a snowmobile, in which a track belt is used having one edge which can be stretched and another edge which can be contracted by turning at least one end roll thereof for guiding the track belt such that the track belt can be bent to a curved position in order to steer the vehicle, wherein a bottom run of the track belt loop is, in front of a cross-wise gravity center plane with respect to a principal driving direction of the vehicle, arranged to be pressed or weighted against a driving surface in a manner such that, in the region of such weighting, a limited area of surface pressure higher than average is created in which maximum surface pressure is substantially higher than average surface pressure in a rear section of a bottom run of the track belt behind said center gravity plane.
