Air system KAMAZ 55102. Air system KAMAZ

KamAZ-55102 is a truck, a dump truck, which is used at various industrial enterprises, on construction sites and in agriculture, for example, as a grain carrier. It is precisely because this truck is used primarily in agriculture that the name “farmer” is assigned to it.

Thanks to the ability to unload not only from the rear, but also from both sides, KamAZ 55102 is best suited for transporting bulk cargo.

Double tire tires reduce pressure on the ground, which makes it possible to load grain from the combine directly onto the field. The machine's carrying capacity is 7 tons, it can be supplemented with a trailer with a carrying capacity of 11.5 tons.

Some modifications of KamAZ 55102 are equipped with a platform with extension sides, which double its volume.

Agricultural truck 55102 is mainly used for transporting goods within the region, since the cabin is not equipped with a sleeping place. Using this KamAZ model allows you to save on cargo transportation, because these vehicles are reliable and repairs do not require large costs. Fuel consumption is relatively low: with an engine power of 225 hp. the truck is capable of reaching a speed of 80 km/h, while consuming 31 liters of fuel per 100 km.

KamAZ 55102 has a pneumatic braking mechanism powered by a compressor. The gearbox drive operates from the air system.

Description of KamAZ brakes

Each car produced by the Kama plant has four types of brake equipment on board.

• Main brake;
• Reserve brake;
• Stop brake;
• Auxiliary brake.

These types of equipment cope with the task without the need for mutual assistance, and as a result, the indicator of the work performed reaches efficiency. If automatic braking is accompanied by the release of air masses from the profile, the machine has an emergency release mechanism. The principle of using the device is to resume operation. Monitoring and signaling sensors for status and performance are also installed.

The main brake reduces the KamAZ speed limit, down to a complete stop. Vehicle stopping devices are located on six wheels of the vehicle. The operating principle of the drive is based on air under pressure. The unit is equipped with two circuits, the action of which extends to the bow and stern axles separately.

Activation of the main stopping mechanism occurs through a foot lever, which transmits the force to the brake valve. Brake chambers are converters of air pressure force into movement of brake pads.

The backup motion damper reduces the speed limit and stops the car when the main brakes fail or the function is not fully performed by the main device.

The stopping system forces the vehicle to remain stationary on a level surface, without intervention from the pilot. Feature of the stopping mechanism, paired with a backup brake. The activation is actual after the lever is moved to the required position.

KamAZ parking and auxiliary brakes:

From the above it is clear that at KamAZ the stopping methods used are the same for the main, backup and stopping motion dampers based on the stern. As for the backup and stopping dampers, they have the same pneumatic propulsion.

An additional motion damper works to reduce the degree of heating of the equipment, the main speed reduction device. This includes the power plant muffler, which switches the exhaust manifold, and turns off the fuel mixture input.

Purpose of KamAZ 55111

Kamaz 55111: technical specifications, reviews, tests, photos and prices - this valuable information is collected in one review! But before we start getting acquainted with the technical parameters, let's find out what the purpose of KAMAZ vehicles is and what makes them remarkable.

The Russian manufacturer of KAMAZ vehicles, the Kama Automobile Plant, has been producing trucks since 1969. During this time, many heavyweight vehicles rolled off the plant’s assembly line, including concrete mixers, chassis, and dump trucks with various types of shipment. Currently, the company is successfully developing and producing such types of equipment as special equipment, buses, trucks, spare parts, as well as production vehicles, which are divided into tractors, flatbeds, dump trucks and others.

Kamaz 55111 is one of the oldest and most popular models, officially produced from 1989 to 2012. Now you can buy this dump truck at car markets at a very affordable price. KAMAZ 55111 is a copy of the original model, which was marked with the numbers 5511. In terms of technical parameters, it is slightly different from the original one, since some changes were made to the design, in particular, the length of the body was shortened, a folding tailgate was added, the springs were strengthened and power steering was added. Scope of application of the dump truck: transportation of bulk cargo, quarry construction, mining industry, in areas where military operations occur, etc.

What modifications/configurations are there?

KAMAZ 55111 has three modifications:

• KamAZ-55111-02, engine 740.11-240, euro 1;
• KamAZ-55111-13, engine 740.13-260, euro 1;
• KamAZ-55111-15, engine 740.31-240, euro 2.

Modifications differ in the environmental standard of the engine. Production of YaMZ engines (Yaroslavl Motor Plant).

Brake Accessories

To improve the brakes on KamAZ, late-release vehicles are equipped with additional equipment that distinguishes the products from the series units:

• Pressure booster, single-cylinder, produces 380 liters per minute;
• The brake valve is two-sectional and controls the main brake via a foot lever;
• Safety, four-circuit regulator;
• A mechanism that reduces the temperature of air under pressure;
• Valve accelerator, reduces rear brake reaction time;
• Valve for proportional change of input value (KAMAZ-65115);
• Connecting adapters.

KamAZ accelerator valve:

Emergency warning and control signals KamAZ

• Indication (visual and audio).

The indication works thanks to sensors located around the perimeter of the system. The indicators are triggered by the operation of the systems (with the exception of auxiliary ones), the contacts initiate the signal lamps to work. Meters that monitor the pressure level are located in containers. Low pressure initiates a short circuit, as a result, the signal lamps on the vehicle's dashboard light up, and an acoustic warning is heard.

• Bypass control devices.

Purpose: to monitor and diagnose the pneumatic drive, if necessary, to bleed off excess air. KamAZ-5410, etc. use actuating devices that brake trailed equipment. Devices for maintaining pressure at the required level make it possible to combine a machine and a hitch equipped with brake pneumatics.

The principle of operation of the KamAZ brake

To understand what the brake system of KamAZ 65115 and other modifications is, let’s consider the functioning of the stopping unit. The part is equipped with all car wheels (43118, 43114, etc.). The mechanism has a similar operating principle, regardless of the configuration.

KamAZ braking mechanism:

The braking mechanism is mounted and assembled on a caliper (2), the end part is flat in shape with holes for the wheel mounting bolts. Two brake mechanisms (7) with a special material that improves braking (9) are fixed with eccentrics (1). A form of brake material with a specific contour that promotes uniform abrasion. The pins correctly position the brake devices in relation to the drum, which is secured to the hub with five bolts.

Shifting the pads through the fist (12) initiates braking. The parts press on the drum, which brakes the wheel. Roller mechanism (13), transmission link from the fist to the pads. The task of the product is to eliminate the friction force and make braking effective. Spring mechanisms (8), four in number, return the parts to their original position. The riving fist (12) rotates in the holder (10). The holder secures the camera. Closer to the end of the shaft, an adjustment lever (14) with a transmission mechanism is attached. The purpose of the casing is to prevent foreign bodies from entering the product.

KamAZ adjustment lever:

The process of wear of parts due to braking is inevitable. To minimize the distance from the shoe to the drum, an adjustment mechanism is provided. The rod is placed in a steel casing (6) with a fitting (7). A wheel with a worm mechanism and teeth (3), located in the housing, has mounting holes attached to the fist and worm (5) with a pressed rod (11). The elastic element (9), is attached with an emphasis to the bolt-clamp (8), holds the round element (10) on the rod (11) in the worm groove, and locks its axis. A plug (1) is fixed to the frame (6) of the rod, holding the disk with teeth.

Axial rotation provokes a worm movement, which causes the disk (3) to rotate, and at the same time the unlocking fist. The fist presses the brake elements, minimizing the distance from the shoe to the drum. Braking initiates rotation of the lever by the brake chamber rod. Before adjusting the brakes on a KamAZ, the locking bolt (8) is unscrewed and, at the end of the process, fixed tightly.

Brake drive

Modifications of KamAZ vehicles are structurally different in speed reduction mechanisms.

Brake system KamAZ 5320 diagram:

Brake system KamAZ 43118 diagram:

The circuit requiring the supply of air under pressure contains: a pressure increase device (9), a pressure reducer (11), a protective element (12), a cylinder (20). From the circuit, pressurized air is transported in the required dose to users. The air damping drive is divided into independent circuits, protected among themselves by means of valves. Air braking drive with five circuits: divided by double and triple regulator.

The first circuit contains: a regulator (17), a cylinder (24) with a means of measuring pressure drops (18), a pressure measuring device with two arrows (5), a lower sector of the brake valve (16), a device for opening and closing the 7th terminal (C); pressure limiting devices 8; cameras 1 (2 pieces); tractor nose wheelbase brakes, pipes.

The second circuit of the aft wheelbase contains: a regulator (17), a cylinder (22) with a valve (19) and a means for measuring pressure reduction (18), means for measuring pressure with two arrows (5), the upper part of the brake valve with two sections (16) , control bypass device (D), damping force regulator, automatic (30), cameras (26) in the amount of four pieces.

The third circuit of the reserve and stopping brake contains: a regulator (13), a cylinder (25) with a valve (19) and a pressure reduction measuring device (18), two valves (7), a control terminal (B and E). Manual brake valve (2), valve (29,32), accumulator (28), pressure reduction control device (27), valve (31,35,34), isolation valve (37), heads (38, 39), device alarm (33).

The peculiarity of the sensor (33) is integrated into the KamAZ brake system circuit so that it turns on warning lights both when using the stopping brake and when operating the main brake.

The fourth circuit does not contain a cylinder and consists of: a regulator (13), an air-powered valve (4), a chamber of a mechanical regulator of the flow area (23), a chamber for the drive of the stupor rod of the power unit (10), and a measuring instrument (14). The fourth circuit supplies air under pressure to other users: air signal, clutch force converter, etc.

The fifth emergency release circuit without a cylinder and execution elements. Consists of: regulator (17), valve (4), regulator (32).

Machines from the Kama manufacturer (53215, etc.) in the section of the pressure increasing device - pressure regulator require the installation of a moisture separator. Installation of the device - a blown beam of the unit. The same reason for installing a twenty-liter cylinder on Kama transport (5490, 5320, etc.). Location: antifreeze section - protective regulators. Dump trucks 55111, 6520 without vehicle and trailer coupling devices.

Device

The device of this vehicle includes:

• air system;
• braking system;
• fuel system and electrical equipment;
• driver's cabin;
• clutch system;
• front and rear suspensions.

The following controls are located in the cockpit:

• auxiliary brake button;
• clutch pedal;
• pedal from the working brake mechanism;
• fuel supply lever;
• gear shift knob;
• steering wheel;
• driver and passenger seats.

The clutch system of KamAZ-55102 (agriculturalist) is equipped with a device that is responsible for installing the middle disk of the drive type. It moves it to the middle position when the clutch mechanism is disengaged. The device does not need to be configured during work. The casing is made in a shape that allows you to fix the truck's compression springs. The clutch pedal itself is suspended, it does not violate the seal of the cabin and does not require additional lubrication.

Air system

The principle of operation and design of the air system of this unit:

1. The pneumatic type drive of the brake mechanism is equipped with a source of compressed air, i.e. compressor.
2. The compressor, the mechanism responsible for regulating the pressure level, the safety element - all these parts protect condensate from freezing in the compressed air flow, and also protect the condensation receiver from damage.
3. From the drive, the purified air flow under pressure passes in the required quantity to other mechanisms.
4. The drive itself consists of autonomous circuits, which are separated from each other by means of safety valves. Each of them acts separately.
5. From the circuits, the compressed air flow is directed directly to the pneumatic signal, the pneumatic hydraulic booster of the clutch system and to the gearbox drives.
6. The drives are supplied with air through a condensation-type receiver; the circuits do not have a warning lamp for a drop in pressure level.

Brake system

This KamAZ model has 4 brake systems:

1. Working. It controls the braking of the vehicle while driving. It is equipped with a double-circuit pneumatic drive. This type of drive affects the front and rear wheels of the cart. The main components are the pads and the drum.
2. Spare. Such a system is necessary to stop transport or slow down movement in the event of various types of malfunctions and malfunctions in the operation of the main braking mechanism. It is combined with a parking system and consists of four accumulator springs, air cylinders, protective, bypass and accelerator valves, a brake valve, hoses and wires.
3. Parking lot. It is used to control the brakes on all wheels of the unit. Under the influence of air flow, the power springs of the batteries are in a compressed state, but when air enters the cylinders, the braking mechanism of all wheels is activated.
4. Auxiliary. This system helps reduce the load on the rear cart by shutting off the exhaust pipes and turning off the fuel supply.

Partial adjustment of the KamAZ brake

Partial adjustment of the brakes on KamAZ is carried out as necessary. The purpose of the adjustments is to achieve the desired distance from the surface of the lining to the drum.

The primary sign signaling the time to adjust the settings of KamAZ mechanisms is the size of the outgoing levers of the brake chambers. The value considered to be the norm for pressure on the foot lever is 20 millimeters.

The desired size is set using the worm of the adjustment lever. Manipulations - on a cold mechanism, the stop brake is moved to the “off” position, the fixing bolt is unscrewed 2-3 turns, then tightened again. The output value of the chamber rods on the wheel sets is set the same, otherwise an unequal force will occur during braking.

Adjusting the KamAZ brake:

Complete adjustment of KamAZ brakes

Before applying the brakes on a KamAZ, the device is dismantled and rebuilt. Worn parts are replaced. Using eyeliner ensures correct installation of the block in relation to the drum. The adjustment is performed using the eccentric rods of the adjustment lever.

The procedure is performed when the distance from the lining to the drum is 0.2-0.4 millimeters. The measurement is made with a plate, control points: the top and bottom of the pad, the value is thirty millimeters from the edge of the pad. At the same time, it is controlled that the plate, 0.1 millimeter in size, does not move freely across its width.
