The design of the brake system of the front loader Amkodor-342 (TO-28)

Pneumatic system

Amkodor 342V loaders do not have a pneumatic system. The pneumatic system is designed to drive brakes and inflate tires. The drive consists of a power supply and two independent circuits. The schematic diagram is shown in Fig. 5.20. The supply part includes a compressor 10 and a pressure regulator 7. Air enters the circuits through a dual-circuit safety valve 6.

Service brake system

The service brake system will allow you to control the movement of the loader, ensuring its effective stopping regardless of driving conditions (speed, load, road profile). It consists of two circuits. I circuit - front axle brake drive. Includes an air cylinder 9, the upper section of the brake valve 4, front brake chambers with spring energy accumulators 1. Circuit II - rear axle brake drive. Includes an air cylinder 9, a lower section of the brake valve 4, rear brake chambers 5. Circuit III is the drive for the backup and parking brake systems, includes a manual brake valve 3 and a spring energy accumulator for the front chambers 1.

Parking brake system

The parking brake system ensures immobility of the loader when the working system is not working and includes a manual brake valve 3 and a spring energy accumulator of the front brake chambers 1 (Fig. 5.20). When the loader moves, the power springs are compressed by air pressure. When the air pressure in the cylinders of the energy accumulators decreases, the springs activate the wheel brake mechanisms.

Backup brake system

The backup brake system is automatically activated in the event of a violation in the service brake system, ensuring a forced stop of the loader. In the event of an emergency drop in pressure in the parking brake system, the springs of the energy accumulators are activated and the loader stops

Mechanical brake release system

It is built into the cylinders of energy accumulators and is manually activated using a key TO-18D.95.00.001 (BRU 20). The key is located in the cabin in the tool box.

Alarm and control system

The operation of the alarm and control system is ensured by sensors and devices of the pneumatic system. Air pressure sensors indicate the air pressure in the circuits; If there is insufficient pressure in the air cylinders, a light on the instrument panel lights up and at the same time an audible alarm - a buzzer - turns on. When braking, the sensors turn on the rear lights. To diagnose the pneumatic system, all brake circuits have control valves. In addition, the valves are the connection point for the hose for inflating the tires.

Pressure regulator

Designed to maintain the working pressure of compressed air within 0.7-0.8 MPa and protect the system from overload with excess pressure. When the upper pressure limit is reached, the compressed air is released into the atmosphere through the throttle hole.

Double circuit safety valve

Designed to separate pneumatic drive circuits and automatically turn off the damaged circuit in order to preserve and maintain the specified pressure of 0.52-0.55 MPa in the undamaged circuit.

Air cylinders

Designed to accumulate compressed air and power system circuits. Condensate is drained and air is released from air cylinders through drain valves. The valve opens by lightly pressing the rod or moving it in any direction.

Two-section brake valve

Designed to control the service brake system. If one of the sections fails, the remaining one remains operational

Manual reverse acting brake valve

Designed to control spring energy accumulators of the drive of parking and backup brake systems. When the loader is moving, the crane handle is in the extreme forward position. If the handle is released, it automatically returns to the extreme position from any intermediate position. Only in the rearmost position is the handle fixed and the air is completely released from the chambers.

Brake chamber type 20/20 with spring energy accumulator

The chamber is designed to activate the brake mechanisms of the front axle wheels. In the event of a leak, the air from the cavity under the membrane 6 will escape into the atmosphere and the loader will be automatically braked by spring energy accumulators. To mechanically release the brake frame, you need to turn the nut (indicated by the arrow in Fig. 5.21), insert the TO-18D.95.00.001 (BRU 20) key all the way into the fixing sleeve and move it by lightly tapping. Installation of 24/24 type brake chambers is possible

ATTENTION: The energy accumulator spring of both the 20/20 and 24/24 type cameras is in a pre-compressed state. To avoid accidents, it is prohibited to disassemble the spring energy accumulator outside a specialized workshop.

Brake chamber type 24 without energy accumulator

Designed to activate the brake mechanisms of the rear wheels.

Hydraulic brake system

Oil under pressure is pumped into the circuit of the service and parking brakes by a pump type NSh6-3E. From the pump, oil is supplied through a safety block with a filter that maintains the pressure of the working fluid into pneumatic-hydraulic accumulators, and then through hoses to individual consumers.

Design and operating parameters of the hydraulic drive systems of the Amkodor-342 (TO-28) front loader

Drive hydraulic system

The hydraulic circuit diagram is presented in Figure 5.9; the list of elements for the diagram is in Table 5.6.1.

The hydraulic system consists of four circuits: » working equipment drive » steering drive » emergency steering drive » hydraulic distributor control drive

All circuits are supplied with working fluid from hydraulic tank B. The hydraulic tank is equipped with a filling neck with a filter, a drain nipple HV, a pressure regulator in the hydraulic tank RB, a drain filter F2 with an overflow valve. To control the level of working fluid, two oil indicator windows are built into the hydraulic tank.

Consists of pump H2, priority valve, check valves KO1-KO3, emergency pump GM, filter F3, hydraulic steering cylinders Ts1 and Ts2 and pressure switch RD1. Pump H2 supplies working fluid from the hydraulic tank through check valve KO2 and filter F3 to the hydraulic steering wheel GR and at the same time through check valve KO1 to the hydraulic distributor P1 of the working equipment. When the steering wheel rotates, priority in the distribution of the flow of working fluid is given to the hydraulic steering wheel. The H2 pump is equipped with a KO2 check valve and a KP safety valve, set to a pressure of 15 MPa. When the steering wheel rotates, the hydraulic steering wheel supplies working fluid to the corresponding cavities of the hydraulic cylinders C1 and C2, which rotate the articulated front and rear frames.

For delivering medium weight cargo to heights, a blockless crane boom is suitable, which is also mounted on the Amkodor 342B. Forklifts are widely used in warehouses and agriculture. In the municipal sector, in winter, the equipment is actively used as a snow blower. In this case, a snow blade is attached to it. The bulldozer blade is usually used for earthmoving work.

The front loader is also used for other purposes, which allows us to call the Amkodor 342B a universal specialized equipment that can easily replace a set of highly targeted equipment (snowplow, bulldozer, truck crane, excavator and other units).

Feedback from owners and operators

Most owners and operators note high power, decent payload capacity and low diesel fuel consumption. This special equipment successfully copes with a wide range of production tasks and works for a long time without any serious complaints.

The loader is easy to operate and repair. Its price-quality ratio is virtually unrivaled. If maintenance is carried out in a timely manner, problems with hydraulics and engine can be avoided. Common disadvantages of the loader, which many people mention, include poor-quality electrical wiring and an insufficiently comfortable cabin, compared to modern foreign analogues. Many people get rid of standard operator chairs and replace them with other, more comfortable ones.

Build quality is not always the best. According to one of the owners, “buying such a car is a pure lottery.” I had a good opinion about the motor during operation. In any case, it pulls much better than the D-245 (“at one time I worked on a PK-33 with such an engine, so I had to do one thing - either drive or lift the bucket”).

Diesel fuel consumption directly depends on the mode in which the loader is operated. Without serious loads, it comes out to about 11 liters, but if you actively put pressure on the pedal and skid, you get at least 25.

Amkodor 342v-01

This modification of the loader is similar in basic parameters to the base model. Its difference is in the smaller volume of the bucket, less compact dimensions (in particular, length), and lower breakout force. But the reach of the bucket edge and the turning radius have increased. Thanks to the extension of the boom, it became possible to load bulk materials, as well as grain, to a greater height. That is, you can use cars with high sides for this. Farmers appreciated this model.

Specifications

Amkodor 342V is capable of lifting and transporting lumpy and bulk cargo weighing up to 4000 kg. The capacity of the main bucket of the model is 2 (3) cubic meters (installed initially); it is also possible to install additional buckets.

An important indicator for this technique is maneuverability. The ability to perform certain operations and the location of operation depends on it. The minimum turning radius of the Amkodor 342B model is about 6 m, which is very good for a bulky machine. The breaking force of the equipment, which determines the power of the unit, is 12,000 kg.

In general, the model in question has excellent performance characteristics:

• tipping load – 80 kN;
• lifting height of cargo for unloading – 3100 mm;
• bucket edge length – 2500 mm.

The long and sharp cutting edge allows the equipment to work with heavy soils (clay and rocky). A high pullout force helps to cope with such soil.

Overall dimensions Amkodor 342V:

• length including main bucket blades – 7500 mm;
• height (to the cabin roof) – 3450 mm;
• height (to the flashing light) – 3500 mm;
• width – 2500 mm.

The total operating weight of the loader is 11,500 kg. Considering the dimensions of the model, this is quite a lot. The large weight is explained by the specific design and orientation. The front axle carries a load of 4,750 kg, and the rear axle – 6,750 kg.

Amkodor 342V is equipped with a modern gearbox providing 4 speeds (from 6.6 km/h to 37 km/h).

Fuel consumption Amkodor 342

The fuel tank of the equipment holds 215 liters of fuel, which saves significant time on additional refueling. The fuel consumption indicator for the loader is 162 g/hp. at one o'clock.

Design

Compact and powerful, the loader features a Z-type linkage system that provides excellent functionality during earthmoving and quarrying operations. The lifting height of the bucket is more than three meters, and the reach of its edge is about a meter. The six-meter turning radius is an excellent indicator. The twelve-ton breaking force is also impressive.

The frame that controls the steering wheel moves using a hydraulic drive and hydraulic feedback. Hydraulics - two-pump, with a two-spool hydraulic distributor. The loading equipment has one hydraulic cylinder that controls the rotation of the bucket. After unloading is completed, the kinematics of the working mechanisms lowers the bucket down.

The diesel engine has a power of 155 horsepower. The fuel consumption of the loader is quite economical - this is achieved by the hydromechanical volumetric transmission.

The hydraulic tank holds 110 liters of fuel, the fuel tank – 215 liters. The formula for determining fuel consumption looks like this:

P=0.7xRxN (units of measurement - kg/hour).

Here R (measured in gkW/hour) is an indicator of specific fuel consumption, N (measured in horsepower) is engine power.

Engine

Amkodor 342V is equipped with a productive 4-stroke 6-row diesel unit of the D-260.1 model. The power plant is cooled passively and by liquid coolant. It includes gas turbine supercharging.

The D-260.1 motor is made of high-strength materials and can withstand the strong pressure present in the system. The resource of the power plant is quite long, and it itself is designed to work in extreme and difficult conditions. Daily operation at excessively low or high temperatures has virtually no effect on the condition of the engine.

Characteristics of the D-260.1 engine:

• working volume – 7.12 l;
• rated power - 155 hp;
• maximum torque – 622 Nm;
• rotation speed – 2100 rpm;
• weight with filling containers – 700 kg;
• compression ratio – 16;
• cylinder diameter – 110 mm.

Frontal buckets Amkodor 342V

Engine power does not affect fuel consumption, so the model is economical with high performance. This effect is achieved by installing a gas turbine supercharging and hydraulic drive. This and other advantages led the model to increased demand, and the manufacturer received greater profits.

Device

The loader is designed with a limited-slip differential, which allows it to move over rough terrain and areas with sticky soil without any problems. Additionally, the vehicle's maneuverability is increased due to the deep and aggressive tread, through which the wheels cling to any soil.

The model uses a hydromechanical transmission that automatically regulates the torque of the power plant. Special devices send signals to the control unit that regulates the fuel supply.

The control mechanism includes the following components:

1. hydraulic drive with feedback;
2. articulated frame;
3. emergency pump.

The wheels installed on the loader are steel wheels with classic rubber tires.

The equipment is equipped with a cabin with small overall dimensions. However, this does not cause inconvenience or discomfort. The thoughtful arrangement of the seat and controls allows you to control the operation of the machine. The operator can adjust the seat height depending on height. The cabin is equipped with many different lighting fixtures that maintain normal lighting in the dark. Rear view mirrors have a wide viewing angle, covering everything that happens behind the operator. The heating system and fan provide comfortable working conditions in winter and summer. The operator's workplace is equipped with protection against unexpected situations in accordance with the latest safety requirements.

Amkodor 342V is equipped with a drum-type brake system. It is typical for this type of technology. The system is driven by a separate hydraulic drive. Each bridge has its own drive device. The loader is designed with a dry single-disc parking brake actuated by a mechanical drive (a rigid spring connected to a lever located in the cab by a steel drive). The model is released via a hydraulic drive.
