How Lightweight Trailer "scientific Slimming"?

With the increasing number of trailers in China, the concept of lightweight has been mentioned more and more. Especially at present, various industries are affected by the epidemic more seriously, the economic situation is sluggish, but the fuel price continues to rise, which also makes many owners pay more attention to the fuel economy of the vehicle, how to earn more income reasonably within the range of the standard load, has become a more concerned issue. Lightweight trailer, just can meet this demand.

As the name suggests, lightweight trailer refers to a lot less weight than ordinary trailer, but the carrying capacity is almost no difference in the trailer. Under normal circumstances, lightweight trailer and ordinary trailer size, but weight can be more than 15% lighter than ordinary trailer.

Because of the current weight charge limit, the trailer weight reduced by one ton, the owner can within the range of a ton of cargo, also can earn one ton more freight.

In addition, from the perspective of transportation efficiency, lightweight trailer can increase by 30-50%, reduce transportation costs by 30-40%, and reduce fuel consumption by 20-30%. Whether it is energy saving and emission reduction, saving vehicle cost, or improving operation efficiency, there are many advantages.

As for the price of lightweight trailer, the price of tractors on the market at present is generally between 250,000 and 320,000, and the price of semi-trailers is generally between 60,000 and 100,000. Of course, the price depends on the owner's choice of brand, performance, model and so on.

Under normal circumstances, the trailer is composed of frame, body, traction device, steering device, suspension, walking system, braking system, signal system, etc., want to reduce the weight of the vehicle at the same time, without affecting the function of each system, is a more test of technology.

So, from what aspects can lightweight trailer generally achieve "scientific weight loss"?

1, girder material selection of high strength steel

As the key bearing part of the trailer, the quality of the girder is directly related to the quality of the trailer to some extent. The selection of good materials can achieve the weight reduction of the trailer itself under the premise of guaranteeing the bearing capacity of the girder. It is understood that the warehouse grid type semi trailer using high strength steel girder can be less than ordinary steel weight of about one ton. However, high strength steel welding process requirements are more strict, and the difficulty is relatively greater, the relevant technology and experience requirements are higher.

In addition, some manufacturers will also choose to use bent beams, which can also reduce a lot of weight than the ordinary T girder, but there is a certain gap in strength between the bent beam and the ordinary car beam, and we need to be careful when choosing.

2. Choose air suspension or lightweight plate spring for suspension

Vehicle suspension can choose lightweight spring, such as the grid type semi-trailer to choose four pieces of lightweight spring, can be used than the ordinary spring weight loss of about 100 kilograms, if the use of air suspension weight loss effect is more obvious, generally can reduce the weight of about 500 kilograms, but also save the weight of the binding bridge attachment.

3, trailer axle selection of high-quality lightweight products

Axle is the key component of the trailer, related to the load bearing, driving and braking functions of the vehicle, to achieve lightweight body, axle is also one of the essential ways.

DARO's new disc-brake lightweight axles, based on data from DARO's trailer axles, can reduce the average weight of a vehicle by about 15%. Choosing a lightweight axle can not only reduce the weight of the body, but also help save fuel, reduce tire damage, and reduce the cost of the comprehensive vehicle.

4, choose vacuum tire or super wide vacuum tire

According to the relevant personnel, vacuum tire in weight reduction and heat dissipation performance is better than ordinary steel wire tire. For example, if the ordinary steel tire is replaced by vacuum tire, the weight can be reduced by about 240 kg. Ultra-wide vacuum tires have more obvious advantages in weight reduction, but ultra-wide vacuum tires need to be made with extended shafts, which will increase some weight to some extent.

5, choose aluminum alloy hub

Generally speaking, the average weight of aluminum alloy hub is about 25-28 kg, vacuum steel ring is generally 46 kg, compared with nearly half of the weight. If the aluminum alloy hub with lightweight trailer axle, body weight can be reduced by 800-1000 kilograms, about equal to a ton of more space.

6, the body of the selection of new materials, while optimizing the structure

Choose better materials, such as high-strength steel, or optimize the structure of the trailer, such as increasing the spacing between the fence trailer fence, or the side all use canvas stop, the top of the carriage does not set a beam, heavy load with tight rope tight door, etc.
