A guide fixed at the front of a ski of a snow vehicle (22) and including two wings (40) of reversed U-Shape, whose web (60) is linked to the lower face of the ski, the guide including means of initialization (64) of a rectangular runner (48) which is laid out sideways, in continuation and in line with the guide. A ski of a snow vehicle used in combination with a wear runner which is laid out longitudinally of the ski, the bottom face of the ski having in its fore end a pair of downward wings (40) acting as knives and spaced to guide the snow on the two sides of the wear runner. The existing methods of stabilization of snow vehicle implying a sole carbide runner are improved by the presence of the guide, which guides the runner through the trails left by the passage of skis of other snow vehicles. The runner is further improved by a rectangular section thereof, which is laid out sideways and longitudinally of the ski and by its being self sharpening.
A guide (34) to fix at the front (28) of a ski of a snow vehicle (22), said guide defining a short section in reversed U-shape comprising a web (60) and two cutting wings (40) protruding from said web to a certain depth in direction of the ground and longitudinally of said ski, said web comprising means for fixing to a lower face (26) of said ski, said guide being employed in combination with a wear runner (48) located under said web and parallel to said wings, said guide being characterized by, when seen sideways, one of its wings covering part of said runner up to 50% of its total length.
A guide (34 FIG. 1) to be fixed to the front (28) of a ski of snow vehicle (22) in combination with a runner which is positioned longitudinally, said guide defining a short section in reversed U or L-shape and comprises a web (60) with means for fixing to a bottom face (26) of said ski and at least one wing (40) protruding from said web, in direction to the ground longitudinally of said ski, said guide being characterized by, when seen sideways, the wing covering part of said runner (48) starting from the beginning of said runner front (50) up to 50% of its overall length.
A ski of a snow vehicle (22) having a sliding bottom face (26) of its front part (28), at least one knife guide (84) fixed on one side or the other of said bottom face, to define a short section in reversed L or U-shape, in combination with a wear runner (48) which is laid out centrally of said reversed U or L-shape and longitudinally of said ski, said short section being characterized by, when seen sideways, said wing partially hiding said runner up to 50% of its overall length, said knives and said wear runner (48) comprising means for fixing to said bottom face (26) of said ski.
