Interesting features of trucks.
Trucks can be equipped with gearboxes with more than 20 gears with an additional two reverse speeds.
Full braking of a truck traveling on the road at a speed of 90 km/h requires 155 meters of travel and 6 seconds of time.
In modern vehicles used for road transport of oversized cargo over long distances, the volume of the fuel tank can reach 800 liters.
Trucks are equipped with various types of braking systems. The most popular are disc, drum and magnetic brakes.
Batteries, which are most often installed on trucks, have a voltage of 24 V.
The maximum number of revolutions of engines used in trucks reaches 2,000 rpm.
Fuel consumption of a tractor equipped with a 400 hp engine. from. and loaded with goods with a total weight of up to 20 tons, averages 30–40 l / 100 km.
In idle mode, the engine of such a car, when loaded with no more than 25 tons, consumes 4 liters / hour.
In many EU countries, trucks have a speed limit of 90 km/h, even when driving on the autobahn.
The pioneer in the use of disc brakes in commercial vehicles is Renault, after which other automakers began to use this type of brake mechanism.
The use of disc brakes contributed to an increase in the stability of the car, as the radius of the wheel decreased.
In the USA, almost all heavy trucks (95%) use drum brakes, while in Europe the majority (85%) of such vehicles are equipped with disc brakes.
A large mass makes the braking of the truck due to the efforts of the driver inefficient, so such vehicles must be equipped with an air brake system. In this case, the operation of the brakes is provided by pre-accumulated energy (compressed air from the receiver), and the driver controls it.
The features of the air brake also explain the hiss that is heard when the truck brakes.
The effectiveness of engine braking is due to the ability of some powertrains to keep the intake valves closed. As a result, gases are compressed by the piston both on the exhaust stroke and on the compression stroke, which contributes to a quick stop of the truck.
There are trucks worth more than 150,000 euros.
The longest road train was created in Australia. It consisted of 45 trailers and had 100 wheels.
On average, road trains in Australia travel up to 500,000 km of roads.
