FIELD: building, road works.
SUBSTANCE: invention concerns land vehicles with an independent guidance system by means of a fixed pulley running on a rail. The guide consists of the fixed pulley (1) with flanges for conducting a land vehicle and a slide rail (16) with an upper surface (18) on which the central part of a fixed pulley (1) slides. The fixed pulley (1) contains established with free rotation on the same bulwark of wobbling and conducting (2) central roller (6) and on either side of from it two flanges or lateral component parts (7) and (8). Each of these three components of a fixed pulley (1) is free in rotation round the directive bulwark (2) irrespective of other elements. The rolling surface (18) of slide rails (16) is limited sideways by two longitudinal round edges (21) and (22).
EFFECT: reduction of non-uniformity of fretting by various parts of block contacting to rail and maintenance of high stability in condition and movement of the guided vehicle.
