JPS57191109A - Vehicle self travelling with single body on land, water and snow-covered land - Google Patents

Abstract

PURPOSE:To improve speed and controllability of a vehicle at travelling on land, snow-covered land and on the water, by constituting the vehicle in such a manner that directional wheels in a ship bottom shaped-front part and retractable driving wheels in a rear part further screw propellers of prescribed blade type laterally in the central part are equipped and driven by a same power source. CONSTITUTION:A barrel bottom part 12 is formed to inverted triangle shape of a hollowed curve, and laterally equipped with each set of cylindrical type screw propeller 3, while directional wheels are retractably provided in a storage chamber 7 to the point end of a barrel 1, further driving wheels 6 are storeably provided in a storage chamber 11 to the rear part. A spiral angle of the screw propeller 3 is formed to a triangular section at a right angle in the front while at 45 deg. in the rear with respect to its rotary shaft. In this constitution, at travelling on land, the wheels 6 are connected to an engine 10 to perform wheel running, while at travelling on the water and snow-covered land, the directional wheels and driving wheels 6 are stored in the storage chambers 7, 11, and the screw propellers 3 are driven by the engine 10 to propel a vehicle. In this constitution, the vehicle can be driven to peform self travelling on land, water and snow- covered land with a same power source at comfortable speed and controllability.
