Successful trial system of all-aluminum body car
May 09, 2018

In this trial, the bus adopts all-aluminum body frame, the body base adopts steel structure, the body frame adopts welding and riveting structure, which is the full bearing junction.

Compose passenger cars. Compared with the general bus, the structure design of all-aluminum body frame greatly reduces the weight of the bus and reduces the energy consumption of the car. Compared to the

The steel structure of the same level passenger car, the vehicle weight loss of 400kg, 100km lower power consumption 3.6-7.2 KWH. Wang said the car's quality has been reduced.

The inertia of the vehicle will also be reduced accordingly, which can effectively reduce the braking distance and improve the acceleration performance, reduce the noise and improve the vibration.

Can improve the safety, driving and comfort of the car.

With a life span of more than 15 years, the recovery rate of body material is high.

At the same time, the car is highly corrosive. Because aluminum has extremely strong corrosion resistance, the service life can be up to 15 years, use this kind of car will reduce after sale.

Maintenance costs. Not only that, it also has a high recovery value that can be recycled. Wang jinghai explained that aluminum alloy body material recovery is high.

More than 95 percent of the 8.5 m passenger cars are calculated at current market prices, and the recovered residual value can reach more than 8000 yuan. The advantages of aluminum, he says.

It is highly recyclable and can be recycled over and over again. Compared with the original aluminum production, the regenerated aluminum has no influence on the performance of aluminum, and the oxygen in the remelting.

The loss is only 2 percent -- 3 percent, and each cycle can save about 95 percent of the energy and reduce the amount of carbon dioxide emitted, which is low.

The carbon economy has huge implications.

Overcome two difficulties: precision problem, process design.

According to chinalco, the difficulties in the project of shudu bus mainly include the problem of machining assembly precision and the design of process and assembly process.

As is known to all, passenger cars are the products with high precision, which is related to the life and safety of the masses. Many buses are still in steel.

The main reason for the structure of the body is that it can not guarantee the performance of aluminum, which can not meet the requirements of machining accuracy. Therefore, aluminum aluminum in southwest aluminum arc.

The precision of the hole spacing, the guarantee of the vertical precision of the hole and the curved surface, and the five large assembly precision guarantee problems, specially prepared the guidance of the shu city bus project.

The book is equipped with a batch of high-precision processing equipment to standardize the machining accuracy.

At the same time, in the process design of processing and assembling process, aluminum southwest aluminum of China has made thousands of parts to be integrated into a three-dimensional simulation, and each step will be taken.

The assembly process is standardized, the process is streamlined, and the design and design of bus welding and assembly is designed, and the assembly process flow of the bus is designed.

To ensure the precision and assembly precision of the passenger car to meet the safety standards of national passenger cars.
