(57) Abstract:The invention relates to the field of engineering and to vehicles with high cross in particular. The vehicle consists of two articulated trucks, interconnected transmission, and has stabilized in roll cargo platform to accommodate passengers and cargo, as well as water cannons and inflatable pontoons in the niches of the platform. This device provides comfortable finding the driver and passengers inside, high traction, maneuvering characteristics. 3 Il. The invention relates to vehicles osobnyakov specific ground pressure, floating on top of the snow.Existing vehicle type "Buran"with one or two control skis have serious shortcomings, especially in the extreme conditions of the North, especially Yakutia, is the vulnerability of the driver and passenger from the oncoming cold air, landing the driver and passenger on a cold seat. There is also poor maneuverability and stability on the one managing the skis in soft snow in the woods, and with two control ski movement in the forest with shrubs impossible. Transport medium is in the "ice" (in snow water), they do lose their mobility. In such situations, often the fishermen hunters and fishermen who are forced to leave the vehicle for his salvation.The purpose of the invention: to provide a comfortable finding the driver and passengers inside the vehicle, provide optimal cargo platform to provide high traction quality vehicle to tow the trailer with the load, the high maneuverability of the vehicle and stability when driving in the woods on loose snow, the possibility of transfer of the vehicle places of education "ice", to ensure the possibility of operating a vehicle all year round.The proposed vehicle is shown in Fig. 1-3.Fig. 1: engine 1, a transmission 2, the main transmission 3, samolocie differentials 4, sprockets drive tracks 5, 6 cannons, couplings include water jets 7, the brake 8.Fig.2: the front section 1, of the rear section 2, the cargo platform 3, the longitudinal hinges swing sections 4, hinges transverse oscillation sections 5, differential stabilizer platform 6, the axle of the front section 7, the axle of the rear section 8, half-shaft gear 9, the satellites 10, the satellite axis 11, the case tikovoi switchgear 5, the Executive hydrochemistry 6, hinge sections 7, supporting the mobile plate 8.The goal is achieved in that the vehicle comprises a drive motor 1 (Fig. 1), through coupling with a transmission 2 is associated with two main gears 3 with samolechenie differentials 4, output elements which through sprockets 5 are connected with crawler tracks 2 (Fig.3). The rear section 2 (Fig.2) equipped with two easily removable cannons, connected by couplings 7 with output elements samolocie differential 4. To increase the displacement of the vehicle in the niches of the platform 3 (Fig.2) on both sides posted by inflatable pantones in the released position. Pumping air into them can be hand or foot pump, and the pump driven from the engine in cumulative high-pressure bladder with subsequent supply of compressed air in the pontoons.Driving a vehicle on water is the steering control 3 (Fig.3) changing the position of the sections in the plan with respect to each other. A cargo platform 3 (Fig.2) equipped with a differential anti-roll stability when driving hard on the bottom and stability when driving on loose snow in the woods. the 8, United with a corresponding section through the differential gear 6. Half-shaft gear 9 axis 7 is engaged with the satellites 10, and through them with polovoy gear 9 axis 8. The satellite axis 11 to the housing of the differential 12 is connected rigidly with the cargo platform 3. When the inclination of the front section in the left side of the axle 7 will turn half-shaft gear 9 in the left side, satellites 10, objetivas on a fixed gear 9 (at the moment) axis 8, is rotated axis satellites together with the housing of the differential, and hence the platform in the same direction, but in the lower half angle. That is, the slopes of the sections in the plan when moving around the area, acting on the axis, hold the platform in the middle position, a positive effect on sustainability. If you tilt the two sections in different directions at the same angle, the platform will retain its original position. When rounding irregularities of the ground in a vertical plane between the pivot node 7 (Fig.3) and the hinges 4 (Fig.2) the difference between the distances is compensated by moving the hinge 4 along the front section. Driving a vehicle is the steering control (Fig.3) via spool distribution device 5 from the hydraulic pump 4 to the Executive cylindricity, containing two articulated lead sections on tracks, the drive motor, which is connected through a clutch gearbox, the two main transmission drive both sections with gear drive shaft gear rims caterpillar tracks, supporting the rolling elements on the caterpillar feeds on the elastic elements, wherein the cargo platform for better stability when driving on loose snow and for better stability when driving on uneven solid ground at the side rolls in different directions stabilized differential device equipped with cabin life support crew, to increase the displacement of a vehicle equipped with inflatable pontoons placed in the niches on the sides of the platform sections, also features a removable water cannons, one in each Board rear sections connected by couplings with pausetime the drive shafts of the crawler tracks.
FIELD: transport engineering; amphibian vehicles.
SUBSTANCE: proposed vehicle has trimaran water displacement body, wheeled propulsive device and water propulsor. Two pressure chambers with fans are installed in bow of body. Surface of body bottom part is provided with bend having two slot-like holes connected with pressure chambers to let out air jets created by fans and forming air cushion in under-bottom space. Wheeled propulsive device is of rolling type and it has individual drive from geared motors. Wheels of propulsive device are made in form of cylindrical housing with flanges on outer surfaces of which round-shape cross slots are milled in number corresponding to number of support and rest flexible members of rim secured by pins in holes of flanges for turning through angle of roll out to form, together with wheel rim and inner engagement of support-and-drive device of vehicle, mechanism with three degrees of freedom implementing rolling system with negative friction providing translational movement of vehicle owing to upward-forward (backward-up-ward) displacement of center of masses. Support-and-drive device can be furnished with covers interconnected by studs. End of upper stud can be made in form of cylinder fitted into extensible grip installed in upper part of vehicle body on its side to change mode of operation of wheel. Water propulsor can be made in form of paddle wheels installed on vertical posts for vertical displacement and containing cylindrical housing fitted in bearings on axle and paddles of rectangular shape or paddles with bevels to build additional traction force and increase efficiency when moving in water or negotiating bogged terrains.
EFFECT: improved operating characteristics of amphibian vehicle.
