Abstract (en)
[origin: CA2660809A1] The present invention lies in the field of clearing bars (3) for the clea ring blade (1) of a snow plough, which clearing bars are defined at least pa rtially in cross section by a curved contour (10). They are based on the obj ect of avoiding undesirable swirling of snow within the clearing blade (1). The invention is based on the finding that the snow is swirled on parts (7) of the fastening means (5) for fastening the clearing bar (3) to the clearin g blade (1). To solve this problem, a design of the contour (10) that is opt imized dynamically in terms of flow is described.
