Trucks and automobiles are vehicles used to transport goods, transport special goods, or perform other auxiliary tasks. Trucks vary greatly in size, performance, and configuration, but most of them have a cab frame body structure that is independent of the vehicle’s payload.
Smaller models may be mechanically similar to certain cars. Commercial vehicles can be very large and powerful and can be configured to install special equipment. Such as garbage trucks, fire trucks, concrete mixers and suction dredges. In American English, a utility vehicle without a trailer or other articulated device is officially called a “straight car”. It is not a truck but a “tractor” that is specifically used to pull the trailer.
Most trucks in use today are still diesel-powered, although small and medium gasoline-powered trucks. They exist in the United States, Canada, and Mexico. It is estimated that by 2027, the world will reach 7%. Electric drive has already occupied the leading position of the largest and smallest trucks. In the European Union, the total vehicle weight is up to 3.5 tons (3.4 tons long; the third9 short tons) are called light commercial vehicles, and the larger ones are called large trucks. Trucks and cars have a common ancestor: the Nicolas-Joseph Cugno ship built in 1769; however, steam locomotives did not become popular until the mid-19th century.
The roads built for horses and carriages restricted these vehicles to a short distance, mainly from the factory to the nearest railway station. The first semi-trailer appeared in 1881 and was towed by an industrial steam tractor.Steam locomotives were sold in France and the United States until the eve of World War I and in 1935 the British road standards changed. Compared with newer diesel trucks, taxes make them uneconomical. 1895 Karl Benz designed and built the first truck with an internal combustion engine; later that year, Netphener converted some Benz trucks into buses.
A year later, in 1896, Gottlieb Daimler (Gottlieb Daimler) built another truck with an internal combustion engine, the Daimler Automobile Truck. Other companies such as Peugeot, Renault and Büssing have also made their own versions.The first truck in the United States was manufactured by Autocar in 1899 and equipped with a 5 or 8 horsepower (4 or 6 kilowatt) engine.
Trucks at the time mainly used two-cylinder engines with load capacities of 1.5 to 2 tons (3,300 to 4,400 pounds). Several improvements were made after the First World War: an electric starter and a 4-inch motor. 6-cylinder and 8-cylinder. Although it was invented in 1897, it did not appear on mass-produced trucks until Mercedes-Benz introduced the diesel engine.
The extended meaning of the term “truck”, “self-driving vehicles for the transportation of goods”, has been in use since 1911. International changes In the United States, Canada and the Philippines, the term “truck” is often used to refer to trucks that are larger than conventional vehicles. Including pickup trucks and other open-top vehicles. In Australia, New Zealand and South Africa, the term “truck” is mainly reserved for large vehicles; in Australia and New Zealand, delivery trucks are usually called ute (short for utility), while in South Africa, it is called bakkie ( Afrikaans: small open container).
In 1923, diesel engines were not common on European trucks until the 1930s. In the United States, Autocar introduced heavy-duty diesel engines in the mid-1930s. The demand is large enough to bring the “DC” (conventional diesel) model to the market. However, engines have been popular in the United States much longer-gasoline engines were still used in heavy trucks in the 1970s.
The UK, India, Malaysia, Singapore, Ireland and Hong Kong use trucks instead of trucks, but only for medium and heavy-duty trucks, and trucks are almost exclusively used for pickups. Body type The refrigerated truck has insulation panels such as walls, roofs and floors. , Used to transport fresh and frozen goods, such as ice cream, groceries, vegetables and prescription drugs.
Most are equipped with double-wing rear doors, but sometimes side doors are also installed. Enclosed vans (called “tilted” in the UK) have walls and roofs to form an enclosed cargo space. There is a discharge door at the rear; sometimes a side door is built in.The concrete mixer has a rotating drum on the inclined axis, which rotates in one direction for mixing, and unloads the concrete through the pipeline in the other direction. Due to the weight and power requirements of the barrel and the heavy work involved, the mixer must be very similar to a dump truck that transports bulk materials such as sand, gravel or construction soil.
A typical dump truck has an open platform that can be folded at the rear and raised at the front. Allow platform material to fall on the ground behind the truck (“tipping”). The platform truck has a completely flat side structure. It provides quick and easy charging, but no charging protection. The semi-trailer has a fifth wheel to pull the semi-trailer instead of the body. Tank trucks are designed to transport liquids or gases.
They usually have a cylindrical water tank, placed horizontally on the chassis.Due to the large number of liquids and gases to be transported, there are many options. Rescue vehicles (“rescue vehicles” in the UK) are used to repair and/or tow damaged vehicles. They are usually equipped with cable supports; wheel/chassis jacks are becoming more and more common on new trucks.
