On April 20, at the Beijing International Auto Show, the Dongfeng Aluminum Alloy Body Hybrid Bus independently developed by Dongfeng Commercial Vehicle Co., Ltd. made its debut. The launch of this Dongfeng Bus will effectively promote the development of urban transportation in the direction of energy saving, environmental protection and more safety.
According to reports, Dongfeng aluminum alloy body hybrid buses use a variety of aluminum alloy profiles and plates in different states to maximize the lightweight and durability of the parts. Compared with similar steel bodies in China, aluminum alloy body reduction Weighing 40%, other parts also use lightweight technology, which reduces the overall vehicle quality by 15.2% compared to conventional hybrid buses of the same type. The fuel economy performance is even better. Typical urban operating conditions are 7.9% lower than conventional hybrid buses.
At the same time, this bus has a very high technical content. The main technologies are: first-generation medium-capacity hybrid bus in the pure electric mode to achieve steering assistance; the car frame uses ultra-high-strength steel, optimizing the frame structure; using the east wind The self-developed high-stress leaf spring material has further reduced the number of leaf spring assemblies; an ultra-light magnesium alloy seat frame, magnesium alloy profiles are used in all seat frames of the car, and the weight reduction effect is significant; All the body skeletons are made of deformable aluminum alloy material, and the body frame connection adopts riveting and bonding; the body adopts integral through-type roof angle profile to connect between the top cover frame and the side frame, which ensures the flatness of the surface, and Improve the overall structural rigidity.
Dongfeng Motor Co., Ltd. is one of the vehicle companies that make up a strategic alliance for automotive lightweight technology innovation. In the National Science and Technology Support Program of the “National Association of Key Technologies for the Development of Lightweight Vehicles and the Integration of Complete Vehiclesâ€, it is responsible for the “Deformation of Aluminum Alloy Applied Technologyâ€. Development and its integrated application on the target vehicle model. The Dongfeng All-Aluminum Body Hybrid Bus displayed at this time is the goal and achievement model of this national science and technology support program project. It studies the deformation of aluminum alloy in the Dongfeng Hybrid Electric Bus. The development of application technology on the vehicle body and the development of lightweight integration technology for the Dongfeng hybrid-powered vehicle vehicle have resulted in the development of a Dongfeng hybrid-powered passenger car that uses a lightweight aluminum alloy body.
