FIELD: transport.SUBSTANCE: snow mobile comprises frame with bearing surfaces composed by steering ski and bearing skis. Frame supports seat and controls, mechanical drive including engine with chain gearing and propulsor to convert and to transmit driver's physical force to propulsor elements interacting with bearing surface and driving said snow mobile. Every ski is arranged on snow mobile frame one side and at two L-like brackets on both sides. Every bracket can rotate radially and is fitted by its long end on the shaft whereat chain drive sprocket is fitted. Said brackets are arranged diametrically opposite similar brackets on opposite side. Shaft with sprocket is arranged at the frame, while opposite end of every bracket is connected with mating point of appropriate ski fitted to make in-planet parallel motion parallel with snow mobile vertical plane. Chain gearing sprockets fitted on bracket shafts are coupled by chain. Axle of one of said supports is engaged with chain gearing drive sprocket.EFFECT: decreased size, better slip.2 dwg |
