FIELD: mechanical engineering. ^ SUBSTANCE: invention refers to the field of mechanical engineering and in particular to a hand-operated wheeled vehicle. The vehicle includes a sealed wheeled platform with four wheel pairs and a body that can be rotated in relation to it, a tower with the position stabilizing mechanism, support rollers, an engine with the coupling engagement the gear box, a central gear box, a shaft line, a control gear, two mechanisms that ensure movement on both rails, a brake, a wheel buffering system, four spare wheels, a propelling screw, four water propellers, a fold cowl. The shaft line provides transmission of the torque through the bevel gearing of the central gear box to the sun bevel gear and further to each of the two adjacent wheel pairs. Swiveling of the body about the central vertical axle of the wheel platform is performed beginning with the control wheel through the chain drive and bevel gear speed reducer. Swiveling of the wheel pairs is performed when the body is swiveling in relation to the wheel platform with the help of the shaft that is hardly attached to the body and to the driving sprocket of the chain drive. The driving sprocket of the upper chain drive is moving along it to some fixed positions with the help of a hollow rod that is hardly attached to this sprocket and is a part the throw-over gear from the driver's place. The shutdown mechanisms for the water propellers are installed on all the bodies of the inter-wheel differentials of the wheel pairs. The yoke lever provides two fixed positions for the bevel gear: I - for switching on the water propeller by enmeshing the tooth gear with the toothed wheel, II - for switching off the water propeller. ^ EFFECT: pivoting motions without slipping of the wheel pairs, and simplification of the design of the drives and the wheel pairs. ^ 1 dwg, 3 dwg |
