KamAZ-65225 truck tractor
The KamAZ-65225 car was developed by the Kama Automobile Plant in order to enter the market with a new truck tractor with high characteristics. The design of the machine includes the possibility of towing heavy-duty semi-trailers weighing up to 64 tons. The maximum weight of the entire road train is declared at 75 tons with a load on the fifth wheel coupling device up to 22 tons. Thus, a tractor with a semi-trailer can transport various types of equipment, including Tanks and other cars of large mass. The presence of a universal coupling device allows the use of KamAZ-65255 together with other types of semi-trailers that meet customer requirements.

In front of the frame is the engine, above which the driver's cab is installed. The latter is mounted on pneumatic shock absorbers and is created taking into account the experience of designing and operating previous KamAZ vehicles. To ensure comfortable work of the crew, the KamAZ-65225 army tractors are equipped with an autonomous heater and a berth at the rear of the cabin. This allows the crew to work in difficult conditions for a long time.
The Kama Automobile Plant completes its own KamAZ-65225 turbocharged diesel engines 740.632-400. At 1900 revolutions per minute, such an engine delivers horsepower 400. Engine-coupled 16 manual gearbox ZF 16S1820 with 8 transmissions. The distribution of torque between the drive wheels is carried out using a mechanical two-stage transfer case with a locking center differential.
The car is equipped with a fuel tank capacity 500 l. The operation of electrical systems is provided by the generator power 2 kW and 2 batteries 190 A • h.
As part of the chassis there are six wheels with pneumatic chamber tires of size 12.00 R20. Drum brakes are used with a drum diameter of 420 mm and a pad width of 180 mm. The brake drive is pneumatic.

Due to the relatively powerful engine (hp 400), the KAMAZ-65225 truck tractor has rather high running characteristics. According to official information, the road train with full weight at the level of 75 t on the highway can reach speeds of up to 80 km / h. The slope of the 10 ° (18%) slope is provided. By reducing the total mass of the train, some increase in performance is possible.
At the request of the customer, the KamAZ-65225 tractor can be equipped with a power take-off connected to special equipment. The composition of the additional equipment is also determined by the customer. For example, the military version of the tractor gets a winch associated with the engine.
