In mid-2008, the Russian flagship for the production of large-capacity trucks , the Ural automobile plant , launched the Ural-6464 long-range bonnet tractor. The new car was the first swallow among domestic saddle towers with a motor compartment that was moved far ahead. Such an arrangement of the engine previously corresponded only to American style.
Unusual layout
The new Ural-6464, the photographs of which are presented on the page, is distinguished by an unusual design, its power and huge technical potential are felt in its contours. The bonnet layout of the engine makes it possible to assemble a spacious cab with rest areas, air conditioning, a refrigerator and many useful devices on the car's frame to help drivers overcome extra long distances.
Ural-6464: technical specifications
The machine is distinguished by parameters that meet the best European standards. Despite the powerful power plant, large payload and high speed characteristics, the Ural-6464 has a relatively modest size.
Weight and overall parameters:
- road train length - 8050 mm;
- tractor width - 2500 mm;
- height - 3195 mm;
- maximum trailer weight - 62 tons;
- the total mass of the road train is 72,000 kg;
- maximum load on the fifth wheel coupling device - 23 tons;
- gas tank capacity - 670 l.
Power point
The Ural-6464 truck tractor is equipped with a domestic-made YaMZ-7511 engine with the following characteristics:
- dry weight of the engine - 1215 kg;
- working cylinder volume - 16.5 l;
- the number of cylinders - 8;
- arrangement of cylinders - V-shaped;
- motor resources to the first overhaul - 80,000 kilometers of conditional mileage;
- maximum fuel consumption at nominal power take-off - 195 liters per 100 kilometers;
- maximum torque - 1715 Nm;
- rated engine power - 400 l. from.
The power plant of the Ural-6464 model is distinguished by a perfect system of forced water cooling, due to which heat is removed from the working unit extremely quickly. This allows you to slow down the process of wear of parts and, in general, significantly increase the overhaul time of the engine.
Transmission
The Ural-6464 base model uses only one type of gearbox; it is a 9-speed unit manufactured by the Yaroslavl Motor Plant, YaMZ-239. The speed range is highly rational, the driver easily finds the right gear in a traffic situation of any complexity.
The gearbox is equipped with a dual-range demultiplicator, providing soft speed switching in the amplitude of the most running parameters. The gearbox control is remote, using a lever drive transmitting manipulations of the main switch located in the cab to the shaft of the demultiplier.
The gearshift mechanism works with the support of a pneumatic pressure booster, which allows the driver to make hundreds of interspeed transitions without much stress. The Ural-6464 model is a good example of a caring attitude towards service personnel working with the latest generation of tractor units.
In addition to standard equipment, the transmission has a special double-acting power take-off. Connecting to the ring gear gives a pulling force of up to 100 l. with., and the connection with the spur gear in the side of the box - 40 liters. from.
The mentioned mechanisms are able to provide stable rotation of any additional devices. This may be additional ventilation systems of the car, various generating devices, mini-power station, battery charging, other non-standard components and assemblies.
Dashboard
The following sensors are located on the shield located in front of the driver:
- tachometer accurately reflecting data on the change in torque;
- speedometer with a scale of 20 to 160 km / h;
- oil temperature sensor in the crankcase, outside the pressure system;
- fuel level in a gas tank;
- battery charge sensor;
- oil pressure and its temperature in the main system.
In a separate sector of the dashboard are located:
- high and low beam switches;
- heating system control;
- rheostats of heating of external rear-view mirrors;
- remote control of air conditioning and ventilation;
- emergency stop switch;
- audio control buttons operating in two modes, remote and direct.
Safety grade
Hood tractors, which include the car "Ural-6464" have good passive safety data. Unlike cabless models, in which the motor is located directly in the cab and poses a real threat in an accident, cars with a forward engine are more traumatic. At the time of impact, the entire front part of the bonnet tractor is crushed, but all units remain outside. In addition, the engine compartment and cladding take on the main collision force. The inertia of the shock decreases significantly.
Service
The trucker engine, like no other, needs regular maintenance, its dependability depends on the correct maintenance. Hood tractors have full access to the engine compartment and to all devices located under the hood. Thus, on the road, you can make most of the simple adjustments, top up the lubrication tanks, tighten the joints.
The hood of the car opens forward in the direction of travel with the help of a powerful lifting device operating on the basis of pneumatics. No additional effort on the part of the driver is required. Three-step ladders on both sides of the tractor allow you to get to the most inaccessible points of the engine compartment and perform the necessary actions.
Comfort level
At the rear of the tractor cab is a resting place. This is a bunk bed with soft mattresses and a complete set of bed linen. The comfort level of the car is favorable for long trips, because you can relax at any time.
