Recently, “lightweighting†has attracted more and more attention from owners. The 9.21 five-member ministries’ joint action against the Chaoyang Super League has made “lightweight†another fire. The purpose of switching to lighter models is to maximize the loading of goods and increase the transportation efficiency without increasing the total cargo weight. But many drivers are still suspicious: such a light truck, on the road in the end fly it? Today, we will explore together where the secret of lightweight trucks lies. Should we not “lose weight†for trucks? 
<br> <br> lightweight lightweight trend this concept was first originated in motorsport, research figures show that, if the automobile 10 percent weight reduction, fuel efficiency can be increased by 6% -8%. The automobile body accounts for about 30% of the total mass of the car. Under no-load conditions, about 70% of the fuel consumption is spent on the body mass.
As the body weight is reduced, the engine output power can produce higher acceleration, the vehicle will have better maneuverability, better acceleration performance at the start, and braking distance when braking will be shortened accordingly. Truck lightweighting is a reflection of the overall improvement of the society and the improvement of transportation efficiency. It is also one of the effective measures to improve the fuel economy of trucks and reduce the emission of CO2 from automobiles.
In the truck industry, the application of new energy automotive technologies such as hybrid, electric and fuel cells is difficult and the prospects are unclear. Therefore, lightweighting has become the most realistic and most effective technical measure for energy saving and emission reduction in the heavy truck industry, and it has gradually become a world truck. The common trend of development.
<br> <br> under the weight saving GB1589 aside aside, it is also gradually becoming lighter needs of most truck drivers.
Mainly because of the new GB1589 policy. Especially in the first four to eighth quarters, many drivers felt that the load given in the regulations was too small. In addition to the weight of the wagon, the actual amount of goods that could be transported was really too small, and the competitiveness among other models was greatly reduced.
Therefore, more and more drivers have begun to focus on lightweight trucks. I heard that lightweight vehicles have become hot, and they may not be able to buy them if they want to buy them.
However, the joint truck has just launched a new National 5-6X4 ultra-lightweight single-tire tractor product. The measured weight of this car is only 8.12 tons, and its safety performance is also very good. Once it is available, it will be warmly received by the card friends. , strength can not be ignored.
Lightweight = cut corners?
For lighter trucks, many truck driver masters still have many doubts: Is the body lighter and safer? Will lightweighting be achieved through cutting corners? ......
Indeed, it does not rule out that very few truck companies take short cuts on the road to pursuing lightweightness, save costs for market competition, blindly pursue their own weight, and blindly reduce vehicle weight. For example, the use of ordinary steel instead of high-strength steel, reduce the weight and cost, the consequences are broken beams, cracking and so on.
In fact, this is the “snapping†or “stealing work cuts.†Although its weight is lighter and its comfort is improved a lot, the “skeleton†of the product is loosened, and it is too “soft†to be skinned and the safety factor is greatly reduced. In the event of an impact, the cab cannot protect the safety of the occupants. If the cab is discarded, it is fatal.
Is China still not a lightweight truck that is really reliable? of course not!
Where's the lightweight?
Lightweight applications in trucks are very extensive nowadays. Lightweight upgrades and explorations can be carried out from various aspects such as the body, frame, cab, powertrain, and transmission system. Take the joint truck as an example. 
Aluminum alloys are the most widely used type of nonferrous metal structural materials in the industry and have been widely used in aviation, aerospace, automotive, machinery manufacturing, marine and chemical industries. Low density is a very good lightweight material. The hubs, air reservoirs, and fuel tanks on trucks can all be made of aluminum alloys. 
The weight of the aluminum alloy wheel is only one-half or less of the weight of the steel rim, and the weight of the truck is perfectly achieved. Taking the example of a 6-axis trailer consisting of a combined truck 6X4 tractor, replacing the 22 wheels of the entire vehicle with aluminum alloy wheels can reduce the weight by 550 kilograms. And according to card friend analysis, aluminum alloy wheels can also reduce the wear of the tire, and the bearing performance is even higher than that of the steel ring.
Airbag suspension 
The airbag suspension can reduce about one-third of the weight compared to the steel plate suspension, and it can also make the trailer's center of gravity lower. It can load more cargo and travel more smoothly with the same volume and the same weight. The combined truck 6X4 ultra-lightweight single-tire tractor is equipped with front and rear 4 airbag suspensions to ensure driving comfort, safety, and stability. The goods are not prone to bumps.
Big singleton 
A single child, as the name suggests, has only one large tire on each side. The average trailer has a total of twelve tires. By the time the big single tire becomes only six tires. Large single tires have the advantages of light weight, low frictional resistance, and strong stability. However, the rated load of a single tire is strictly regulated, so the overload space is relatively small. And in order to avoid sudden driving during driving, it is impossible to drive, so when driving a single tire trailer, be sure to prepare a spare tire in the car.
Carbon fiber composite material of the chassis <br> <br> According to the latest research shows that the use of composite materials manufacturing vehicle chassis, the vehicle body can be effectively reduced up to 40% by weight. To a certain extent, it means increased carrying capacity, emissions and lower fuel consumption. In an electric vehicle design concept newly devised by a car company, a carbon fiber composite material integrated lightweight chassis was used. However, this kind of composite material is still in the experiment and research. After how long the Chinese driver can see such a truck coming to market, there are still many unknowns.
Weight reduction does not mean blind weight loss. The slimming of trucks still requires quality and health. Xiao Bian reminds our friends and friends that when choosing a lightweight vehicle, we must also select the light truck that is suitable for us according to our actual operating route, the goods we transport, and the requirements for the vehicle. Not only to "gentle" but also to return in peace!
