RF patent No. 37974, IPC B62D 61/10, publ. 05/20/2004).

A disadvantage of the known technical solutions is that the chassis has insufficient layout capabilities to accommodate large-sized technological equipment.

The task to which the claimed technical solution is directed is to improve the layout capabilities of the automobile chassis, allowing the installation of various technological equipment, while maintaining high throughput.

The problem is solved due to the fact that a three-axle four-wheel drive automobile chassis made with a 6 × 6 wheel arrangement, containing a hinged cab, under which the engine is located, a frame with front and rear overhangs, consisting of spars of a constant section without bends in the horizontal plane and cross members, made with expansion towards the cab, front and rear suspensions equipped with stabilizer bars, rocket rods, the upper of which are located along the axis of the chassis, brake chambers located in the upper parts of the bridges inside the frame, a transfer case installed between the gearbox and the middle bridge and fixed to the frame with two brackets and a reaction rod, a cardan drive equipped with cardan shafts for transmitting torque from the engine to the transfer case and from the transfer case to the front and middle axles, an air intake, an air purifier, a muffler mounted in front of the middle bridge under the frame, an exhaust pipe, a battery box, five receivers, two of which are combined into a block and placed d a battery box, and three are combined in a block and placed on the frame on the right side, the fuel tank, cross-axle differentials are made with an increased distance between the front and middle axles, and additional side members with cross members are fixed at the rear of the frame from the bottom, while the gearbox equipped with a power take-off, the transfer case is located in the narrow part of the frame, the muffler is installed in front of the unit of three receivers, and its exhaust pipe is led out to the right.

In addition, the chassis can be made with a distance of 5400 mm between the front and middle axles, and additional spars can be fixed to the frame with cheeks using a bolted connection.

The set of distinguishing features, namely, that the chassis is made with an increased distance between the front and middle axles, additional side members with cross members are fixed at the rear of the frame, the gearbox is equipped with a power take-off, the transfer case is located in the narrow part of the frame, the muffler is installed in front of the unit of three receivers, and its outlet pipe is brought out to the right, it allowed to create an off-road chassis with improved layout capabilities that allow you to install chnoe technological equipment (Special superstructure).

Analysis of known technical solutions for scientific, technical and patent documentation showed that the set of essential features of the proposed solution was not previously known, therefore, it meets the condition of "novelty."

The claimed technical solution is illustrated by drawings, which depict:

FIG. 1 - three-axis all-wheel drive automobile chassis, side view;

FIG. 2 - the same, top view;

FIG. 3 - the same front view;

FIG. 4 is a view A in FIG. one.

A three-axle all-wheel drive automobile chassis made with a 6 × 6 wheel arrangement comprises a cab 1, a load-carrying frame 2, formed by side members 3 and cross members 4 with front and rear overhangs. Spars 3 are made without bending in the horizontal plane, with a constant cross section along the entire length. The frame is equipped with an amplifier mounted on its inside.

Frame 2 is made with expansion towards the cab. The width of the frame at the rear is 774 mm to allow the installation of 8.5 × 20 rear dual steel disc wheels with 12.00R20 tires. In the front of the frame there is a cross member and side brackets to which the cab buffer and additional steps are attached. In the rear part of the frame 2 from the bottom there are additional spars 5 with cross members 6, which are fixed by the cheeks 7 by means of a bolted connection. The presence of additional spars 5 allows you to install additional superstructure equipment on the chassis.

Cabin 1 is located above the engine and is configured to tilt forward to service the engine.

The power unit consists of a V-shaped eight-cylinder engine 8 of increased power for liquid cooling with turbocharging, a single-plate diaphragm clutch with a pneumatic hydraulic amplifier and a mechanical sixteen-speed gearbox 9, equipped with a power take-off, mounted on the front of the frame 2 on three supports and a supporting support. The use of a gearbox 9 with a power take-off allows the maximum power take-off from the engine and its transmission to special superstructure equipment. The engine cooling system uses an oversized radiator, an electronically controlled high-performance fan. To ensure the required power, an air-to-air charge-air cooling system is installed, consisting of a heat exchanger installed in front of the main radiator, inlet and outlet pipelines.

The engine air supply system consists of an air intake 10, an air cleaner 11 with increased multi-cyclone output, nozzles and pipes connecting the air intake, an air cleaner and engine cylinders. The air intake 10 is attached using the bracket and stand to the rear wall of the cab 1.

In the expanding part of the frame 2, a fuel tank 12 with a capacity of 350 liters is installed on the left. To the right of the frame is a box of 13 batteries. The receivers 14 are combined into blocks of two and three receivers, which are located respectively on the right under the battery box and on the right on the frame in front of the middle bridge.

On the right side, under the frame, in front of the block of three receivers, there is a muffler 15 with an exhaust pipe led to the right.

The chassis has three driving axles: front axle 16, middle axle 17 and rear axle 18.

To transfer torque from the engine 8 to the steered front axle 16 and rear axle bridges 17, 18 with the help of cardan shafts 19, a transfer box 20 is installed in the narrow part of the frame between the gearbox 9 and the middle bridge 17. The location of the transfer case 20 is selected based on the layout of the car : increasing the distance between the front and middle axles up to 5400 mm, ensuring favorable angles of the driveshafts from the transfer case during operation, the use of a more powerful engine and gearbox with power take-off and. The transfer case 20 is attached to the rams 2 with two brackets. To reduce the efforts in the mounting brackets of the transfer case, an additional reaction rod 21 is mounted on the left, fixed on one side to the bottom of the transfer case, and on the other side to the frame. Bridges have a central final drive, wheel gears, a cross-axle differential lock mechanism. Beams of bridges welded, stamped, enlarged section. Brake chambers 22 are located in the upper part of the bridges inside the frame.

Between the bridges 16 and 17, additional cross members 23 are installed.

The rear suspension 24 is attached to the frame using brackets 25, 26. The reaction rods 27 are forged, of increased length with double-bearing rubber-metal hinges, the upper reaction rods being located along the axis of the chassis.

The front and rear suspension of the car are equipped with stabilizers 28 lateral roll.

The claimed technical solution allows you to create a three-axle all-wheel drive chassis of the car with an improved layout that allows you to install various processing equipment, special add-ons, for example, a fire truck.

The three-axle four-wheel drive automobile chassis of the proposed design meets the condition of industrial applicability, and can be manufactured on standard equipment using previously developed technologies.
