<p>Method for 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, thanks 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.</p> |
