Description

 Usage - pneumatic tracks for tanks, self-propelled guns, tractors, all-terrain vehicles, cars for riding on the tundra, snow, ice, marshy soil, desert and water movement.

 An analogue and a prototype of the invention can be considered an invention as. USSR 264 924, cl. B 62 D 55/08, 1968 with small tracked tracks, from which the tracked chassis of the machine is known, comprising guides and rear wheels, a tracked system of tracked tracks.

 The disadvantage of previously designed pneumatic tracks is the desire to follow the design of metal tracks both in shape and in the number of "tracks". A lot of tires are created, the tracks are small, all chassis are expensive, require large and frequent repairs and, due to their inefficiency, have not been developed.

 The technical task is to create a pneumatic track for driving on different soils.

 This technical problem is solved in that the caterpillar chassis of the machine, comprising guides and rear wheels, a caterpillar track system with tracks, is equipped with wheels and coulters attached to the tracks, guide rails - I-beams with oval ends for the movement of the track wheels and transverse steel bars, while the steering wheels are made in the form of gears with six teeth and in the amount of one for light vehicles or two for heavy on each track, each track is a gear This part of the wheel rim is a kind of pneumatic cushion with a trapezoidal shape on the side, and the caterpillar system is attached to the side walls of the machine and its internal fasteners using the indicated transversely arranged steel beams piercing the specified I-beams, and the track is covered with an apron on top and side. .

 In FIG. 1 shows a tracked chassis, side view; in FIG. 2 - gears with six teeth; in FIG. 3 is a side view of the trapezoidal track; in FIG. 4 is a side view of the truck with one pair of protrusions; in FIG. 5 is a top view of a truck with rolls; in FIG. 6 is a side view of a truck with rolls; in FIG. 7 is a side view of a truck with two pairs of protrusions; in FIG. 8 is a side view of a floating tank with an apron; in FIG. 9 is a top view of a floating tank with an apron; in FIG. 10 is a rear view of a floating tank with an apron; in FIG. 11 - tracked chassis with steel beams, side view; in FIG. 12 - tracked chassis with steel beams, top view; in FIG. 13 - tracked chassis with steel beams, rear view; in FIG. 14 - caterpillar chassis with a support beam, side view; in FIG. 15 - tracked chassis with a support beam, top view; in FIG. 16 - the location of the support beams in the lower part of the machine; in FIG. 17 - tracked chassis of a light vehicle with an I-beam in the center; in FIG. 18 is a steel frame, side view; in FIG. 19 - steel frame, top view; in FIG. 20 is a steel frame, rear view.

 The proposed design of the tracks is the sixth part of the wheel, i.e. they are quite large, have a trapezoidal shape on the side and consist of a solid steel frame (Fig. 1, p. 7, Fig. 3, p. 7), tires with or without a chamber (ibid., p. 1), coulters (p. 3, ibid.), A wheel (item 2) having bounding discs on both sides, as shown in item 5, FIG. 6, and moving along the guiding I-beams (p. 6 - in all figures).

 On the side, the steel frames have articulated protrusions, so that the protrusion of the frame enters the recess of the other and is held together by a rod located in the middle (Fig. 18, 19, 20, p. 22, 23). The system of frames and hinges must be very strong, since the integrity of the track depends on this. In all figures, the hinges are indicated in paragraph 4.

 To the bottom of the track frame, in addition to the openers (item 3), one (Fig. 5) or two pairs (Fig. 7) of protrusions (item 19, all figures) are attached, between which a cylindrical view of the rolls (item 17, fig. 5 and 6). As the caterpillar moves, these rolls (p. 17) sequentially enter the cutouts of the gears (p. 5, all figures) of the guide and rear wheels. The gears are mounted on the shaft 16, which from the outside enters the I-beam and is fixed there in the gear cutout with cylindrical ball bearings (Fig. 7, paragraphs 16, 25). On the other hand, the shaft penetrates the second I-beam, is also attached to it using a wheel with ball bearings (ibid.) And passes through the side wall (p. 14, all figures) of the tank, tractor, etc. and connects to the motor inside the tank, tractor, etc. (p. 18, all figures).

 The gear on the shaft 16 is fixed tightly, in the other three joints with I-beams and a wall, the shaft can rotate freely thanks to ball bearings.

 Two options are possible: the first option, in which there is one gear located between the upper and lower tracks in front and behind (Fig. 4, 5), or in a pair of gears, as shown in FIG. 5. This second option is especially necessary for heavy vehicles, tanks, it provides caterpillar movement without distortions, with the simultaneous harmonious impact of traction on both the right and left side of the track.

 The caterpillar as a whole will retain the greatest strength and harmony in movement if the I-beam on both sides has an oval-shaped shape, in which H is greater than R (Fig. 1).

 I-beams along which track tracks move are connected to the tank, tractor, etc. by steel beams (item 10, all figures), which pass through the wall of the machines and are connected to the internal mounting structures.

 From above and from the side, the caterpillar is covered by an apron (p. 20, all figures), due to which the protection of the tracks of the tracks from external influences is increased. Due to this, light tanks can float, since air cannot penetrate above the lower edge of the apron. The upper tracks in this case move in the air, and the lower tracks in the water and with their tires rake back the water, moving forward (Fig. 3, 5).

 Steel support beams are located in the lower part of the car body, passing through the side walls of the tracks (Fig. 13), or fasteners, connecting inside the machine with the beams, make a bend down. Thus, when the machine’s motor starts to work (paragraph 18, all the figures), it drives the shaft 16, from which the gear 5 moves. From its impact on the rollers 17, the trucks experience traction, using the wheels 2 they move like on rails , along the I-beam 6. The ball bearing system (item 25) reduces friction. The relationship between the wheels of the truck, the I-beam, ball bearings, the shaft 16, the gear 5 and its mounting system of item 19 are visible in FIG. 17. The same figure depicts an option that is possible for relatively light machines, when the I-beam is in the center of one beam and two gears. They also strengthen the system, do not allow distortions to occur.

 The dimensions of the chassis of the tracks and tires may vary depending on the weight of the machine and its purpose. The weaker the soil, the "cushion" of the tracks should be wider, the total area of contact between the tracks and the ground will be greater, and the pressure on a square centimeter of the earth's surface is less. Such caterpillars will allow transporting large loads across the tundra, marshland, desert, without getting stuck and not crippling the soil cover, i.e. such caterpillars are highly environmentally friendly and useful throughout most of Russia, with its vast expanses of tundra and swamps. In addition, such chassis will allow you to move on bad roads and completely without roads.

 They will allow tanks and any other military equipment on wheels to move in the snow, swamps, water, desert, tundra, etc. with great speed, becoming an important element of the "quick reaction force", an important tool in the country's defense system. Thus, the proposed chassis with a pneumatic caterpillar can have both military and economic importance.
