From November 12-15, 2015, the 3rd China International Commercial Vehicles Exhibition was held in Wuhan Wuhan International Expo Center. Looking at the products exhibited by many companies in this exhibition, a very important trend is to reduce weight. Whether it is a vehicle or a component, it is taking a lightweight route. This is also related to the current stage of gradual unification of the standardization of transportation equipment in China. The lighter the weight, the stronger the carrying capacity and the more fuel-efficient.
At this auto show, many truck manufacturers introduced their own lightweight products. All of them are based on the original improvement of some components, while ensuring the carrying capacity while reducing the body quality. In the final analysis, the lightweight design of a car is still a lighter component. At the exhibition, a number of accessories manufacturers launched their own lightweight products.
Five axle manufacturers to prove safety as a lightweight <br> <br> currently the largest commercial vehicle exhibition, the exhibition has attracted more than 500 enterprises to participate, they are distributed in the number Wuhan International Expo Center B 1-6 Hall, where Hall B4 is an accessories hall, brings together many commercial vehicle parts suppliers from all over the country. The largest of these manufacturers is axle manufacturers, including international brands such as Guangdong Fuhua, BPW (Meizhou), SAF (Saif), Guangzhou Huajin, and Foshan Yonglitai.
These axle manufacturers have introduced their own lightweight products, but some manufacturers and technicians said that lightweight axles, while reducing their own weight, also hope that the equipment they support, such as wheels, can also be lightweight, although light Quantification can reduce body weight to a certain degree, but its carrying capacity will be somewhat reduced. They also recommend lightweight vehicles to be used in the case of standard loading.
In addition, in order to further reduce the body weight, many axles are designed to have a single wheel structure, so that with a good aluminum alloy wheel, it can ensure the body's load-carrying capacity can also reduce the body's own weight.
On the other hand, an important change for the axle is the integrated design of the bearings in the wheel end. Before this, when you want to replace the brake pads, you must remove the entire bearing, which takes a lot of time. Now many manufacturers have thought of this problem and made some improvements. Specifically, the bearing is made into a unit structure. Bearings, oil seals, and grease are integrated in the unit. The bearing clearance is free from adjustment. When you replace the brake pads in this way, you only need to twist the wheel cover to remove the entire bearing, which can be easily done.
At present, several domestic axle manufacturers are striving to improve their own round of maintenance-free mileage. For example, Guangdong Fuhua has launched a maintenance-free round of 1 million kilometers in Europe for five years. However, due to the complicated domestic road conditions, Severe overload conditions and other factors, the product can not achieve European standards.
Alloy wheels will be greater tendency for rapid logistics <br> <br> moving axle weight except route to go outside, there is a very important product is the wheel. At present, most of the steel wheels used in China are of low cost but heavy weight. The corresponding price of aluminum wheels is 4 times that of steel wheels. If a 22-wheel trailer is replaced with aluminum wheels, the cost will increase by 70,000-80,000 yuan. It is precisely because of cost factors that the domestic use of aluminum alloy wheels is basically a product of some truck manufacturers.
In addition to the lighter weight of aluminum alloy wheels, its heat dissipation is good, and the thickness increases a lot. However, at present, the domestic environment and the phenomenon of overload are very common, and aluminum alloy wheels are mostly suitable for standard loading, which means that its large-scale promotion needs to be determined according to the implementation of policies.
On the whole, lightweighting is a big trend. From every component, every product is making every effort. For the user, a lighter body means more load. And for the fast logistics market, lightweight design can save fuel and reduce costs.
