- a dual-purpose off-road truck with a 6 × 6 wheel arrangement, produced at the Ural Automobile Plant in Miass (Russia), including for use in the armed forces in the Susha family of unified army vehicles until 1998.

Today, the Ural-4320 series is produced with YaMZ diesel engines with a capacity of 230-312 hp. With. environmental class from Euro-4. Tire size - 14.00 R20 (370 R508). Model OI-25 - produced by the Kama and Rosava factories. Model Ya-307M - produced by the Belshina and Rosava factories.

Story

Production of trucks and chassis of the Ural-4320 line began on November 17, 1977[1] and in fact this series is still being produced today, albeit in a significantly modernized form.

The main difference between the Ural-4320 and the carburetor Ural-375D line is the economical and high-torque diesel engine. As of 1986, more than a million trucks were produced. Initially, the Ural-4320 was equipped with a KamAZ-740 diesel engine, but as a result of a fire at the KamAZ engine plant on April 14, 1993, supplies of this engine to third-party manufacturers ceased, and engines began to be installed on the Ural-4320 (as well as all subsequent models and modifications of Ural trucks). YaMZ-236 and YaMZ-238 Yaroslavl Motor Plant. Due to the resulting shortage of diesel engines, some of the Ural-4320 produced in 1993-1994. was forced to be equipped with a ZIL-375 carburetor engine, that is, the production of the Ural-375D model was actually extended, but with a type 4320 engine compartment tail. Initially, modifications with the YaMZ-238 engine were distinguished by an outwardly longer engine compartment, while cars with the YaMZ-236 engine retained the same engine compartment as that of vehicles with a KAMAZ-740 engine (the difference is that vehicles with YaMZ-236 have an air filter on the right wing due to a different, more dense layout of the engine compartment). Since the mid-2000s, all cars, regardless of engine model, have been produced with an extended engine compartment.

Since the mid-1990s, a wide bumper with headlights appeared on the Ural-4320 and Ural-5557, and plastic plugs appeared in the wings, at the old headlight mounting points. However, exclusively for the needs of the Ministry of Defense, on a special order, until now [ when?

] cars are supplied with a narrow bumper and headlights in the wings. Since 1996, the production of the lightweight two-axle (4x4) 4.2-ton truck Ural-43206, structurally completely identical to the three-axle Ural-4320, began.

Ural-43206 with IVECO cabover cab
In 2009-2014. On cars of the 4320 series, a cabover cab of the Iveco “P” type (produced by the UralAZ-IVECO joint venture) with an original rounded integral fiberglass hood tail (the “-57” and “-58” configurations) was installed in small series. Subsequently, such a cabin began to be installed on the Ural-4320 chassis and in a cabover version. With the transition to Euro-4 engines, only modern diesel engines of the YaMZ-6565 and YaMZ-536 series began to be used in the Ural-4320.

In 2014, in order to increase the reliability of chassis components and assemblies and increase the mileage before overhaul, the Ural-4320 series was upgraded to the Ural-M series while maintaining the 4320 type cab.

In the fall of 2020, the Ural-M series was upgraded to the Ural Next series by installing new generation cabs of the GAZelle Next type with the original plastic tail of the engine compartment, as well as a number of improved components and assemblies.

• Load distribution of the equipped vehicle = front axle - 4550 kg, rear bogie - 3500 kg
• Gross vehicle load distribution = front axle - 4635 kg, rear axle - 10,570 kg

It was first presented at the Russian Expo Arms-2009

in Nizhny Tagil. On June 10, 2011, at a display of military equipment at the training ground of NIIITS AT 3 Central Research Institute of the Ministry of Defense of the Russian Federation in Bronnitsy, the car was presented as Ural-4320-0010-31.

Casspir Mk6

Armored vehicle MPVI

(eng. Mine Protected Vehicle for India), manufactured at the joint venture
Defense Land Systems India (DLSI)
at the
Mahindra & Mahindra
plant in Prithla near Faridabad (Haryana). The order of these six vehicles by the government of Jharkhand was due to the need to combat pro-Maoist rebel groups operating in the state.

The vehicle is made in the form of a structure based on an all-welded V-shaped body and the base of the chassis of trucks of the Ural-4320 family. Modifications are offered with 4 × 4 and 6 × 6 wheel arrangements, equipped with a YaMZ-236NE2 turbocharged diesel engine (maximum power 230 hp / 169 kW) and a YaMZ-236U manual transmission. This solution was chosen to reduce the cost of the machine, the cost of which is stated to be from 350 thousand dollars. According to a statement by the director of business development of BAE Systems Land Systems South Africa

Johan Jooste, “the use of Ural elements made it possible to reduce the cost by a third.”

In the 6 × 6 version, the vehicle has a length of 7.59 m, a width of 2.67 m, a ground clearance of 380 mm, and a combat weight of 14.32 tons. The armored vehicle can accommodate up to 18 personnel, placed in individual suspended shockproof seats and can be configured in the form of an armored personnel carrier, multi-purpose or command vehicle. It is stated that during testing, the vehicle withstood, without harm to personnel, the detonation of a twenty-one-kilogram charge under the wheel (the accuracy was confirmed by a video of the corresponding tests posted on the Internet [2]) and a fourteen-kilogram charge under the body of the vehicle. It is possible to attach additional ballistic protection[3].

Ural-4320VV

"Ural-4320VV"

The armored vehicle was designed according to the Motovoz-2 program according to the technical specifications of the main command of the Russian Ministry of Internal Affairs on the basis of the Ural-4320 6 × 6 multi-purpose vehicle chassis. The armored vehicle is equipped with a YaMZ engine of Euro-4 standard, has mine protection and is made with single-volume armored a body that can accommodate up to 17 fighters with full weapons. The layout of the armored vehicle is free, which makes it possible to install various variants of combat modules and equipment on it, depending on the assigned operational tasks.

The car was first presented in 2013 at the Russian Arms Expo-2013

in Nizhny Tagil. This vehicle will become the basis for a whole family of tactical protected vehicles, which have a high degree of unification and are distinguished by different wheel formulas.

Chassis Ural-44202

The frame of the Ural-44202 car is riveted, consisting of two stamped spars of variable cross-section, which are connected to each other by 6 cross members and a front buffer.

The front suspension consists of 2 longitudinal semi-elliptical springs, operating together with hydraulic shock absorbers of a telescopic type of 2-way action. The upper lugs of the shock absorbers are attached to the bracket brackets through rubber bushings, and the lower lugs are attached to brackets welded to the axle housing. Hydraulic shock absorbers dampen vibrations resulting from elastic deformations of the truck's suspension elements when it moves over various uneven surfaces.

The rear suspension is of the balancing type, the ends of the springs are inserted into the eyes of the support brackets. The springs are attached by stepladders to balancers that swing on the axis of the balancer. Brackets are pressed onto the axle, each of which is attached to the balancer brackets with four bolts. Pushing and braking forces are transmitted from the axles to the frame through 2 upper and 4 lower reaction rods. Lateral forces are transmitted through springs.

The reaction rod joints are ball joints. Pins with a shortened cone are mounted on the upper reaction rods on the side of the bridges, which are kept from turning in the brackets by segment keys. The head of the reaction rod is sealed on one side by a gasket, which is installed under the cover, and on the other by an O-ring. The impacts of the axles on the frame, resulting from vehicle wheels hitting obstacles, are softened by a buffer. We limit the downward movement of the axles by pinching the end of the spring in the support bracket

Wheels 254G-5O8, 4OOG-5O8 and ZZO-5ZZ have the same design and differ in size, in accordance with the used tires 14.OO-2O model 0I-25, 12OO x 5OO-5O8 model ID-P284 and 11OO x 4OO-5ZZ model O-47A. The wheels are detachable, consisting of rim bases, beads, lock rings and lock ring stops. The wheels are equipped with a tire pressure regulation system. It allows you to control the pressure and maintain it within normal limits, as well as increase the vehicle's cross-country ability by reducing the air pressure in the tires. It provides the opportunity to continue driving the vehicle if the inner tube is punctured, without replacing the wheel (the wheel valves on undamaged wheels must be closed).

This car has a large number of different advantages that make it almost irreplaceable when used in difficult off-road conditions. There are many different modifications. This will allow you to easily select a suitable vehicle of the Ural 43206 type.

Cabins "Ural-4320"

The Ural-4320 trucks were equipped with a metal two-door cabin designed for a driver and two passengers. The classic, traditional Uralov cabin has been produced for fifty years now, and, of course, the comfort indicators in it are infinitely far from modern ones. Although: the driver's seat is adjustable, there are ventilation and heating systems, there is power steering, and it is possible to equip the cabin with a sleeping place. If desired, the Ural-4320 can be equipped with an air conditioner, an independent heater and a Webasto pre-heater.

To create more comfortable travel conditions and better safety, since the spring of 2009, successful experiments have been undertaken to equip the newly developed Urals with new-style cabins. This is a license-manufactured cab without a hood with a fiberglass tail. It has three separate anatomical chairs with headrests, armrests, and seat belts.

In the interior decoration and cladding there are modern materials that provide good noise and heat insulation, a steering wheel with lower spokes (which does not overlap the instruments). All controls are located in close proximity to the driver; the parking brake and transfer case control drive is pneumatic (which made it possible to remove the levers from the passenger compartment). The new cabin provides comfortable working conditions for the driver. But the charismatic appearance of the car, of course, completely takes away from it.

Transmission

The design of the car uses a clutch model YAM3-182 - dry friction type, single-disc, with an extension-type diaphragm spring. The gearbox is installed YAM3-2Z6U - mechanical, five-speed, three-way. It is equipped with synchronizers in all gears except first. The gear ratios are as follows: 1st – 5.22; 2nd – 2.9O; Zya - 1.52; 4th - 1,OO; 5th – O.664; rear - 5.22.

The transfer case is mechanical, 2-speed, with a lockable center cylindrical differential, which distributes torque between the front and rear axles in a ratio of 1:2, with the drive to the front axle constantly engaged. Top gear ratio – 1.21; low gear - 2.15.

The cardan transmission is an open type, with four shafts and hinges on needle-type bearings. All axles are driven, axle housings are combined, consisting of a cast middle part and axle housings that are pressed into it. The front axle is steerable, with disk-type constant velocity joints.

The main transmission is double, through-type, a pair of bevel gears with a spiral tooth, and a pair of cylindrical helical gears. The main gears of all axles of this vehicle are interchangeable. The differential is a symmetrical conical, with 4 satellites. The axle shafts are fully balanced, the connections to the hubs are splined.

Features of operation

Problems with brakes often arise. This issue is resolved by installing hydro-pneumatic amplifiers. The optimal solution in this case would be FUSO.

Difficulties arise with cars that have been taken out of storage. If the car is more than 10 years old and has not been used for a long time, it is necessary to replace all oil seals, as well as bearings in the hubs.

According to user reviews, the cabin is quite comfortable while driving. But significant difficulties arise if you need to sleep in it. Because the car is simply not designed for this.

It is also important to remember that the operating manual for this type of vehicle expressly prohibits sleeping with the heating unit turned on in the cabin.

Therefore, the optimal solution would be to install a heater from a third-party manufacturer.

Important features that all owners without exception pay attention to and that need to be paid attention to include:

• during intensive use, overheating of the heater boiler is possible - this usually occurs when ice plugs occur in the supply pipes; this can be corrected by pouring hot water over it;
• the heater does not turn on - the cause is usually clogged injectors (corrected by disassembling the injectors and washing them in kerosene or gasoline);
• increased noise of the bridge while driving at high speed - the clearance in the gearbox bearings has been increased (it is necessary to restore the preload);
• deterioration in controllability - usually the safety valve pump seat comes loose (you will need to disassemble the pump and screw the seat to the desired position).

The list of possible faults is quite extensive. It is best to familiarize yourself with all of them in advance. This will avoid various operational problems.

Exterior

The body of a domestic car is a metal platform with a folding side at the rear. It is equipped with benches, an awning and removable arches, additional lattice sides. The structure is made in the form of short overhangs, which allows for increased cross-country ability. The total curb weight is 8,265 kg. The weight of the equipment or cargo being transported can reach 6,855 kg, and up to 11.5 tons can be towed.

The standard configuration includes a 3-seater cabin on the frame, which is assembled from thick sheet metal, which is also stamped. As for the glazing, it is made in such a way that the visibility of the driver of the car makes it possible to fully monitor the situation on the road. For this purpose, side rear view mirrors were made, which are very convenient.
