FIELD: transport. ^ SUBSTANCE: invention relates to transport machine building. Wheel with retractable studs consists of metal rim and pneumatic tire installed on it. Inside pneumatic tire, polyurethane wave-shaped spring is installed. Metal studs are cured in wave-shaped spring. To provide stud propulsion guide bushes are cured into pneumatic tire. Inside pneumatic tire, rubber bag with valve is placed which provides variation of amount of studs protruding from pneumatic tire. Between wave-shaped spring and bag, elastic rubber band is placed which serves to lower friction between bag and wave-shaped spring. ^ EFFECT: higher flotation ability of vehicle while driving over snow, as well as possibility to change traction coefficient of tires for various road surfaces. ^ 3 dwg |
