First, lightweight trends. Lightweight design is not only to save materials, reduce self-weight, and increase the load quality; more importantly, it aims to reduce energy consumption, reduce emissions, improve operational efficiency, and drive safety. This year, heavy-duty lightweight design is mainly reflected in the following aspects:
1, the use of variable section less leaf spring structure leaf spring leaf springs are all metal parts, the weight is very large, reducing the weight of leaf springs, but also reduce the quality of the important measures for the preparation. The variable cross-section leaf spring is composed of several leaf springs of variable cross-section in the longitudinal direction. Variable leaf springs not only reduce weight, but also improve ride comfort and service life by reducing friction between leaf springs. In addition, the use of rubber suspension or air suspension can also reduce the weight of the suspension system.
2, the use of single-frame frame beam compared to the leaf spring, the frame of the larger weight, effectively reduce the weight of the frame, will greatly reduce the vehicle's overall quality.
3, the use of composite cab is the use of composite materials up to the assembly, especially the outer cover: front panel, angled panels, fenders, bumpers, and even the top cover, have used a large number of composite materials. On the one hand, this effectively reduces the weight of the entire vehicle. On the other hand, due to the good formability of the composite material, the molding structure can be more complex, more beautiful, and more accurate in size than the metal stamping.
4, the use of aluminum alloy material Aluminum alloy is less dense than steel, so in some parts of the composite material can not be replaced, you can use aluminum alloy materials, including sheet metal parts and castings. Wheel rims, engine blocks, transmission bodies, etc., are also cast aluminum alloys to a large extent, and they are designed to provide sufficient strength and stiffness while minimizing weight.
5, the use of high-strength steel using high-strength steel plate, can reduce the thickness of the steel plate, thereby reducing weight. Cold-rolled steel sheets used to manufacture the car body and hot-rolled steel sheets used to make the frame can be made of high-strength steel to increase the strength of the car and reduce its own weight.
Second, the natural gas trend. The natural gas heavy truck market will become a new growth point in the heavy truck market. During the “12th Five-Year Plan†period, it will be a period of high-speed growth of natural gas heavy trucks, which will surely become an important market segment for heavy truck companies to compete for. Natural gas heavy truck refers to a gas-fueled heavy-duty vehicle that uses natural gas as fuel (CNG is compressed natural gas; LNG is liquefied natural gas). According to different fuel use conditions, it can be divided into single-fuel natural gas vehicles (engines use only CNG or LNG as fuel), dual-fuel natural gas vehicles (using diesel + natural gas, or using gasoline + natural gas as a fuel vehicle). The most widely used at present is a single-fuel natural gas vehicle.
Third, the high-end heavy trend. With the soaring oil prices in recent years, increasing overloading of governance in various regions of the country, and the development of the road transport industry, transportation companies have paid great attention to the economics of road transport, which has led to the development of heavy transport. At present, all domestic heavy truck companies have launched their own high-end products. For instance, the automobile fleet’s “land fleetâ€, Jinan CNHTC’s “HOWOA7â€, SAIC Iveco Hongyan “JIE SHIâ€, Shaanxi CNHTC’s “DeLong F3000â€, FAW Jiefang “J6â€, Dongfeng “Tianlongâ€, and Hualing "Star Kema" and so on.
1.Welding materials
In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.
The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications. Luoyang Golden Egret Company has any kind of welding materials include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod, Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.
