The beginning of the 2000s was marked by a significantcrisis in the automotive industry throughout Russia. It was at this time that the Likhachev plant sharply reduced the output of medium tonnage trucks. This led to the formation of a colossal niche that industrialists from the Kama Automobile Plant could occupy. He also owns the development of the promising KamAZ-4308. About this unique brainchild of Kamovians, we'll talk as much as possible in detail in the article.
At that time, the idea of producing a newthe truck was very, very risky, and therefore the engineers made every effort to minimize the cost of creating a new model, because the probability of failing in case of failure was very high. The vast majority of truck units were unified with the main line, but all the details were completely unsuccessful due to the impressive difference in overall dimensions. In 2003, the KamAZ-4308 appeared in mass sale and almost immediately gained wide popularity, because thanks to its parameters it perfectly suited to the constantly toughening requirements of traffic rules and regulations in large cities. And in general, medium-duty trucks have always been in high esteem.
KamAZ-4308 is a new model of the famous Russianbrand, which is characterized by the lowest possible weight for such a design. At the same time, the truck has a pretty nice look, although it causes a somewhat ambiguous feeling for the average user. The cab of the car was borrowed from its "congeners" of the 1970s, although it was tested and acquired a more original look. She received a single windshield, a high roof, upgraded optics, a front bumper streamlined configuration. However, the features of the predecessors were also preserved - small headlights, door handles and side windows. Head lighting is placed on the sides of the radiator grille. In addition, the KamAZ-4308 cab is one of the best in the lineup of this car. It is worth noting that the number of elements subject to negative effects of corrosion has significantly decreased. To the disappointment of many consumers, the galvanizing of the cabin is not yet performed by the manufacturer, and this is definitely a big minus. According to the preliminary order of the buyer, there is a version of the cabin with one sleeping place. Suspension of the "head" of the car is installed on four springs of elliptical shape, which quite well extinguish all arising fluctuations from roughness of the road in the course of driving. The cabin's upholstery is unshaped, and the torpedo in the latter versions is made of plastic, not steel, as it was before. Instruments left almost all switches. The driver's seat has many settings and is equipped with an air suspension so that it is convenient for a person to adjust it to their personal dimensions.
KamAZ-4308 is used in many industriesmodern national economy. For this model, many types of add-ons are available, but the most popular is the on-board platform. With its help, you can transport a variety of loads weighing not more than twelve tons. In addition, the chassis has the possibility of installing special equipment used in the urban economy. It is also possible to operate the machine as a part of a road train. The truck is excellent for transporting on international routes and can transport lots of different goods between warehouses located within the boundaries of large cities.
Manufacturers made KamAZ-4308 with fairly compact linear dimensions and a wheel formula of four by two. The dimensions of the truck are as follows:
The car is able to overcome the angle of ascent 25%. The maximum possible speed of movement of the car does not exceed 105 kilometers per hour. At the same time, the fuel consumption is very low and fluctuates between 14-16 liters for every 100 kilometers of travel. However, in the case of a full load and a negative ambient temperature, this figure will already be 23-24 liters. The truck can run off-line for a long time, as its fuel tank has a capacity of 210 liters. KamAZ-4308 uses pneumatic tires and discs with a size of 245/70 R19.5.
Truck compares favorably with its competitorsThe fact that he has an exclusive engine. Directly the development of the motor began in 2001 in Naberezhnye Chelny. At that time the plant actively cooperated with the American industrial giant Cummins. It was the engineers from the USA who provided the Russians with a suitable motor for the car. Initially, the KamAZ-4308 engine had a capacity of 140 horsepower and a volume of 3.9 liters, which corresponded to the standards of the Euro-2 standard. But over time the car received a motor in two versions - four-cylinder and six-cylinder. Each of these variants of engines is equipped with a fuel system with electric control of Common Rail. Due to the use of a plate of steel, which protects the cylinder block in the lower part, it was possible to achieve a significant reduction in noise level. And the power plant itself is equipped with a four-valve cylinder head. The water pump and the compressor drive are equipped with a poly-V-belt type belt with an automatic tensioner. A fan is installed on the front sock of the crankshaft, and this is the most optimal variant for the boneless cars from a technical point of view. Fast and efficient heating of the engine is guaranteed by the presence of a viscous coupling. Of the negative features of the motor it is worth noting quite frequent and annoying many drivers breakdown starters, but on power plants in recent years, this gap has been eliminated. In addition, the increased vibration of the motor itself can be explained by the fact that it has excessively rigid own cushions.
KamAZ-4308 - the first biaxial brand car,which has in the frame of the longitudinal members with a constant cross section. This innovation made it possible to release several wheelbase versions. The suspension springs themselves are parabolic, small-leaf, having a small own weight. In order to improve the course of the machine, their length is within two meters. Springs require periodic lubrication and do not cause difficulties in the repair. Special rubber elements installed on the bracket brackets, well extinguish the clang of springs during the journey of the car without load on bumps and hummocks.
In already more modern versions of KamAZ wasthe chassis has been substantially modified and adjusted. The car received a rear air suspension, which has electronic control, which allows the operator to lower or raise the rear of the car within 100 millimeters at the request of the operator.
KamAZ-4308, the technical characteristics of which are given above, is equipped with pneumatically driven brakes, the discs of which are well ventilated. The manufacturer of this unit is Haldex.
Clutch truck - single-disk pullingThe construction is supplied by the Sachs brand, which is the "daughter" of the most powerful concern from Germany ZF. In turn, the drive has not undergone any major changes. As for the gearbox, nowadays the car is equipped with a nine-speed transmission ZF9S109, which is absolutely necessary for using the truck as a road train. By the way, this PPC is used by many European cars in many ways also because it has a fairly high margin of safety.
Particular attention is paid to the driving bridgeKamAZ-4308 (photo below). This medium-tonnage unit is produced in China and therefore, of course, its high quality is irrational. However, the design of the bridge has a unique hypoid gearbox, as well as the blocking of interaxle differentials, which significantly increase the passability of the machine.
The unambiguous positive qualities of KamAZ-4308, the characteristics of which guarantee him the opportunity to be among the leaders of the automotive Russian market, are:
So, how much is really good in practice?KAMAZ-4308? The responses of the owners say that in general the machine fully justifies the money invested in its purchase, but nevertheless there is a whole list of nuances that can be described as negative. Among them are:
Studying in general KamAZ-4308, reviews of whichgiven above, we can conclude: the machine has a stable demand in the consumer market and is worthy of competition to its foreign counterparts. Trucks are capable of long-term operation and are characterized by optimum maintainability, and replacement of parts and assemblies can be made in a variety of climatic conditions, which is especially important for Russia with its extensive geography. At the same time, many repair and restoration works can be carried out independently, without recourse to outside specialists, and this is also an additional saving of money for maintenance of the medium tonnage.
