The utility model is illustrated by drawings, which show:

Figure 1 - dump truck, side view;

Figure 2 is the same, a top view;

Figure 3 is the same front view;

Figure 4 is the same, rear view;

Figure 5 is the same side view with a raised platform.

The dump truck of the KAMAZ-6522 model contains a car chassis with a 6 × 6 wheel arrangement.

The automobile chassis comprises a cab 1, a load-carrying frame 2 formed by side members 3 and cross members 4. The side members 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 is reduced at the rear and equal to 774 mm to ensure the installation of the rear twin steel disc wheels 8.5 × 20 with tires 12.00 R20. In front of the frame, a towing cross member is installed, to which the headlight panel, spoiler and additional steps are attached.

Cabin 1 is located above the engine and is configured to tilt forward to service the engine. To ensure the installation of an engine with increased power and a radiator with a heat exchanger, the cabin is shifted forward.

The power unit 5 consists of a V-shaped eight-cylinder engine of high power liquid-cooled with turbocharging, a diaphragm double-disc or single-disk clutch with a pneumohydraulic amplifier and a mechanical

a nine-speed or sixteen-speed gearbox mounted in front of the frame 2 on three legs and a support leg. The engine cooling system employs an oversized radiator and an increased 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.

On the right side, under the frame, in front of the middle bridge, there is a muffler 6 with an exhaust pipe 7, which is led above the middle driveshaft to the left to the gas bypass box, after which the exhaust is either upward or to the left.

The engine air supply system consists of an air intake 8, an air cleaner 9 with a multi-cyclone increased performance, nozzles and pipes connecting the air intake, the air cleaner and the engine cylinders.

The air cleaner 9 is attached using the bracket and stand to the rear wall of the cab 1.

In the middle part of the frame 2, a fuel tank 10 with a capacity of 350 l is installed on the left. To the right of the frame is a box of 11 batteries. Receivers 12 are combined in blocks of two and three receivers, which are located respectively on the right under the battery box and on the right on the frame.

The chassis has three driving axles: the front axle 13, the middle axle 14 and the rear axle 15. To transfer torque from the engine to the steered front axle 13 and the axles 14, 15 of the rear bogie using the driveshafts 16, a transfer box is installed between the gearbox and the middle axle 17. The location of the transfer case 17 is selected based on the layout of the car: maintaining the vehicle base 3600 mm, ensuring favorable angles of the driveshafts from the transfer case during operation. The transfer case is attached to the frame with two brackets. To reduce the efforts in the mounting brackets of the transfer case, an additional reaction rod 18 is installed on the left, fixed on one side to the lower part of the transfer case, and on the other hand 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 19 are located in the upper part of the bridges inside the frame.

The rear suspension 20 is attached to the frame using brackets 21, 22. The reaction rods are forged, of increased length with double-bearing rubber-metal hinges, with the upper reaction rods located along the axis of the chassis.

The anti-roll bar 23 is mounted on the rear axle at the rear. A safety bar 24 is installed at the rear of the frame.

To ensure the horizontal position of the frame increased the height of the bracket 22 of the rear suspension, the length of the strut 23 and the height of the levers of the upper reaction rods.

In connection with the increase in the height of the car to ensure safety requirements, the length of the arms of the beam 24 is increased.

On the frame 2, a subframe 25 of the platform is fixed by a system of couplers and brackets. The subframe 25 is made precast welded from stamped spars and cross members. The platform frame spars are straight along the entire length without bends.

On the subframe 25, a platform 26 is installed, made of an all-metal, box-type type, with a protective visor covering the space between the cabin and the platform. Platform 26 has a tailgate with automatic locks.

On the front side of the platform mounted spare tire 27.

To prevent the platform 26 from tipping over during unloading, a platform stabilizer 28 is provided.

To keep the platform 26 raised to the maximum tipping angle, locking fingers are provided that are installed in the bushings of the platform mounting brackets and the holes of the platform bracket located behind the platform tipping axis. At the rear of the platform subframe 25, a platform bracket is welded through which the subframe is attached to the vehicle frame. IN

the bracket has two holes, one of which coincides with the axis of the tipping platform, and the second is designed to install a locking finger for fixing the tilted platform. When lifting the platform 26 at an angle of 50 °, the axis of the hole in the bracket of the subframe coincides with the axis of the hole for the locking pin in the longitudinal beams of the platform.

The tipper vehicle is equipped with a platform raising and lowering mechanism containing a telescopic hydraulic cylinder 29, four-stage single-acting, a power take-off with a pump attached to the vehicle’s gearbox, a control unit consisting of a control valve with a safety valve and three electro-pneumatic valves, an oil tank with filter elements , hydraulic and pneumatic pipelines, platform lift restriction valve.

The control mechanism for raising and lowering the platform is electropneumatic, remote from the driver's cab.

The inventive device allows you to expand the functionality of the car.

Tipper vehicle can be performed on standard equipment using modern materials and technologies.
