摘要： A personal self-propelled vehicle for travelling on snow using ski comprises a closed-loop flexible ribbon configured to envelope the ski over its length so as to pass under at least a portion of a sliding surface, two rollers and configured for installation on longitudinally opposite ends of the ski and to interact with the ribbon. The roller is a driving roller and is engaged with a motor comprising a control means and with the ribbon to transfer force for translational movement thereof. The roller is a guiding roller. The ribbon canvas has multiple via openings divided by webs and substantially constitutes a lattice. Dimensions and positions of the openings and parameters of the webs between them are selected so the sliding surface of the ski abuts on snow through the openings during motion of the vehicle, while the webs sink in snow under load of the vehicle bearing the user and provide repulsion from snow packed by the ski, thus assuring the ski sliding in longitudinal direction.
