METHOD OF SNOWMOBILE MOVEMENT AND SNOWMOBILE FOR ITS REALISATION

摘要

FIELD: transportation.;SUBSTANCE: group of inventions relates to the method for movement of a snowmobile and a snowmobile. The method of snowmobile movement consists in provision of interaction of propeller elements with the support surface. The snowmobile propeller is made in the form of two skis, besides, on the running surface of the specified skis they make notches, providing for movement of skis to one side. Each ski is placed at one side of the frame of the snowmobile ad is installed at least on two L-shaped brackets at each side. Each bracket is arranged as capable of radial rotation and is installed with a long end on the shaft, on which a chain drive sprocket is installed. Brackets at each side are arranged diametrally oppositely to similar brackets at the other side. The shaft with the sprocket is placed on the frame. The other end of each bracket is connected to a response area of the appropriate ski, which is installed as capable of making flat-parallel motion in the plane parallel to the vertical plane of the snowmobile. Sprockets of the chain drive arranged on shafts of brackets are connected to each other by a chain drive. The transmission ratio of the specified drive is selected as equal to one. The snowmobile comprises a frame with support surfaces made in the form of a steering ski and support skis. On the frame there is a seat and control elements, a mechanical drive of the snowmobile preferably with a chain drive comprising a master sprocket with pedals and a slave sprocket, and a propeller for conversion and transfer for a physical force from a driver of the specified snowmobile to elements of the propeller, interacting with the support surface and driving the specified snowmobile.;EFFECT: provides for design simplification and improved sliding of a snowmobile.;2 cl, 2 dwg
