Chassis Ural 4320-41. Ural 4320 chassis technical characteristics

In 1978, at the automobile plant in Miass, production of the Ural 4420 truck tractor was launched. It was made on the basis of the Ural 4320 off-road truck. This vehicle became extremely popular in the military department and construction, among workers in the oil and gas and other industries. farms. A powerful engine, high ground clearance, and the 6x6 formula allowed the car to travel on any impassable roads. The SUV passed on its advantages to the receiver, model 44202. In our review, we will talk about the technical characteristics of the Ural 44202, and get acquainted with the operation of components and mechanisms.

Power unit

The vehicle is equipped with a four-stroke diesel engine from the Yaroslavl Motor Plant, model 236-HE2.

Let us list the technical characteristics of the motor of the Ural 44202 truck tractor:

• working volume: 11.15 l;
• power: 230 l. With. (169 kW);
• Max. torque: 882 N.m (90 kgf.m.);
• number of cylinders: 6 (V-shaped arrangement).

The environmentally friendly operation of the unit complies with European standards Euro-2.

The power plant is characterized by direct injection, turbocharging, and closed-type liquid cooling (forced circulation). A thermostat is responsible for creating the desired operating mode in the system, which automatically maintains the desired temperature. To make it easier to start the unit in cold weather, a pre-heater is installed in the engine compartment. The adaptability of the components and mechanisms of the vehicle of the Ural Automobile Plant to our harsh climate allows it to be operated in the temperature range from -45 to +40°C.

The car is capable of reaching a speed of 85 km/h. Fuel consumption per 100 km of Ural 44202 is on average 40 liters per 100 km. The fuel tank has a volume of 300 liters.

Cabin

The Ural 4320 was equipped with various types of metal cabins. The classic version used a 2-door, 3-seater version. The first cabin samples for the model were developed in the middle of the last century; since then, changes inside have been minimal, so in terms of comfort the car is much inferior to modern modifications.

The driver's seat has several settings to select the optimal position. The cabin has heating and ventilation systems to maintain a normal microclimate. Optionally, the cabin is equipped with a berth. Upon request, installation of air conditioning, Webasto preheater and independent heater is available.

Since the spring of 2009, certain versions of the Ural 4320 have been equipped with new-style cabins, created jointly with Iveco. The cabover version with fiberglass tail is equipped with 3 anatomical seats with headrests and armrests. The interior decoration is made of high-quality materials with good heat and sound insulation. The controls are located next to the driver. The new cabin is significantly ahead of the previous version in terms of comfort, but in terms of charisma it is clearly inferior to it.

The body of the Ural 4320 is made in the format of a metal platform with a tailgate. It is equipped with benches, removable arches, an awning and additional sides. To increase cross-country ability, the structure is made in the form of small overhangs.

Chassis

The vehicle frame consists of two interconnected spars having a variable cross-section. The elements connecting them are six transverse beams and a buffer.

The front suspension includes the following components:

• two semi-elliptic springs;
• double-acting telescopic hydraulic shock absorbers;
• rubber bushings for shock absorbers;
• brackets.

The shock absorbers are fastened using bushings through the upper lugs to the bracket brackets, and on the opposite side - through the lower lugs to the bracket itself.

The rear suspension consists of springs that are inserted into the eyelets of the brackets. They are secured using balancers on the balance axis. This device is also equipped with reaction rods (four lower and two upper), which transmit braking and pushing forces to the frame from the axles.

Device

The basis of the car is a load-bearing riveted frame made of high-strength steel and characterized by increased rigidity. The design provides short rear and front overhangs, thereby increasing cross-country ability. The platform for transporting people and cargo is made of metal. It has lift-up side seats and an opening tailgate. The body assumes the possibility of installing an awning, arches and mounting sides on both sides. Some modifications received a wooden platform. The sides of the Ural 4320 are lattice or solid. The design provides for a front location of the unit. To access the engine, the hood opens upward. On the sides there are wide, flat fenders that protect the cabin from foreign objects and dirt while driving.

The truck has a 6 by 6 wheel arrangement. The model is equipped with single wheels with automatic adjustment of the air filling of the chambers on 3 drive axles. Recommended tires: 14.00-20 OI-25.

Ural 4320 has a dependent front suspension on semi-elliptic springs. It consists of 2-way shock absorbers. The rear suspension of the car is also dependent (on springs with reaction bars). All truck axles are drive axles. The steered wheels are located on the front axle.

The car is equipped with a friction clutch with a drive equipped with a pneumatic booster. The 2-speed manual transfer case has a permanently connected drive to the front axle. The Ural 4320 is equipped with a fully synchronized transmission produced by the Yaroslavl Motor Plant. The gearbox has 5 speeds, switched mechanically.

The brake system includes a dual-circuit working and single-circuit spare brake system. There is also an auxiliary braking system with pneumatic drive from the exhaust system. The mechanical parking brake system is equipped with a brake drum on the transfer case.

At the rear of the frame and at the front of the rigid bumper there are powerful towing devices made in the form of a towing mechanism and hooks. Thanks to this, the technical characteristics of the model were improved.

The developers of the Ural 4320 also took care of the driver. The steering in the latest models has a hydraulic booster. The cabin is equipped with a heater that maintains normal temperature in cold weather. The driver's seat is adjustable in 3 directions (up-down, forward-backward and backrest tilt). The instrument panel is located at a convenient distance from the driver. The instruments are easy to read, and the driver can reach the switches and buttons without getting up from the seat. The truck has a convenient and large glove compartment and a shelf for storing items. There is a document box under the passenger seats.

In the basic version, a 3-seater cabin made of stamped sheet metal is mounted on the frame. Thoughtful glazing guarantees good visibility and allows you to control the situation on the road. Large rearview mirrors also help with this.

Other types of cabins are also available:

• 3-seater all-metal 2-door cabin;
• 3-seater all-metal 2-door cabin with sleeping bag (this option is currently discontinued);
• modern spacious bonnet-type cabin with a sprung driver's seat and plastic tail;
• cabin based on the GAZelle Next module (3- and 7-seat versions are available).

Options include luxury cabins, a differential lock system, ABS, battery compartment insulation, an additional tank and a traction winch.

Brake system

The vehicle has three different braking systems:

1. The working system consists of drums, shoes, hydraulic cylinders (2 per mechanism). Interchangeable pads are placed on the supporting axes. Their adjustment is carried out using an eccentric based on the state of wear. The drive consists of two circuits that act separately on the driving front and rear axles.
2. If the main system circuit fails, the backup device is activated. Its role is taken over by the current circuit.
3. The parking braking system includes a drum and two shoes.
4. Auxiliary (compression type) – helps reduce the speed of the vehicle when descending. The output gas pipelines of the power plant are blocked by flaps, which helps to slow down the car.

Such combined braking helps to effectively hold a tractor with a heavy trailer.

Price of new and used Ural 4320

The cost of a new Ural 4320 car varies significantly depending on the version:

• chassis - from 1.9 million rubles;
• on-board version - from 2.1 million rubles;
• onboard vehicle with CMU – from 3.8 million rubles;
• tanker – from 3 million rubles;
• log carrier - from 2.8 million rubles;
• cargo-passenger version - from 3.1 million rubles.

There are relatively few used Ural 4320s available. Here prices range from 0.3 to 1.8 million rubles. The cost is influenced by the condition of the car, year of manufacture, area of ​​use and equipment.

Steering system

This unit consists of the following components:

• steering column;
• mechanism;
• drive;
• hydraulic booster (power steering).

Different types of control are used on different modifications of truck tractors:

– screw – nut (ball) – rack – sector;

- worm - side sector.

The column is connected to the steering mechanism using cardans and an intermediate support. The latter has closed-type bearings that do not require lubrication, which facilitates their operation.

Modifications of "Ural" 44202

Several modifications were made based on tractor 44202 from the Miass Automobile Plant. Let's introduce some of them.

Version 3511-82. This model differs from its predecessors in having a cab without a hood, which was borrowed from the Italian Iveco tractors.

Here are the main technical characteristics of the cabover Ural 44202 series M:

• permissible load on the fifth wheel coupling device – 12 t;
• king pin diameter – 2';
• wheel formula – 6x6;
• Fuel tank capacity – 300+210 l.

The machine is equipped with a power take-off (PTO), an additional power take-off (PTO).

Next 5311-74. A modern model of the Ural truck tractor. Designed for transporting semi-trailers on any roads in harsh climatic conditions.

Prices

The price of special equipment varies significantly depending on which model we are talking about. Currently, a regular one can be purchased for 250-300 thousand rubles. This price is explained by the fact that this type of truck is available only on the secondary market. In this case, we are talking about machines that have already had a fairly long service life.

At the same time, a more recent variety, which is assigned the index 44202-59, will be available at a price starting from one and a half million. Finally, a more modern tractor (cabless), whose index is 44202-3511-80, will cost a potential buyer two million rubles.

Thus, the Ural 44202 is an unpretentious and productive hard worker, perfectly suited for domestic off-road use. This vehicle is capable of transporting cargo over any terrain and does not retreat from the complete absence of a route, mud and uneven terrain. The car is very budget-friendly and does not require labor-intensive and costly maintenance, while it has an absolutely powerful engine.

Modification characteristics:

• curb weight of the vehicle – 8.19 tons;
• total weight 21.12 tons;
• tow hitch weight – 29 t;
• permissible load on the coupling device – 12 t;
• Tire size – 425/85 R21.
