Requirements of automobile parts in automobile manufacturing

Automobile manufacturing is a highly specialized industry, especially when it comes to special-purpose vehicles such as fire engines, there are stricter requirements on the selection of parts and manufacturing standards. As an indispensable part of the rescue operation, the performance of the fire truck is directly related to the rescue efficiency and personnel safety. Therefore, in the manufacturing process, there are clear standards and requirements for every component used.

1. Refractory materials

First of all, considering the extremely harsh working environment of fire engines, they often have to face dangerous situations such as high temperature and flame. Therefore, when selecting exterior materials and interior decoration parts of the car body, materials with good heat resistance and flame retardancy must be selected. For example, special steel or treated composite materials are used to increase the resistance to high temperature.

2. Strength and stability

Fire engines often need to carry a large number of water tanks, foam fire extinguishing agents and other equipment, which puts high strength requirements on the chassis and frame structure. Therefore, it is necessary to fully consider and adopt high-strength alloy steel or other suitable metal materials in the early stage of design to ensure that the whole vehicle has sufficient rigidity and deformation resistance. At the same time, in order to ensure the stability and safety during driving, special attention should be paid to the design optimization of suspension system.

3. Quick response mechanism

The fire fighting task requires to arrive at the scene quickly, which not only tests the technical level of the driver, but also depends on the acceleration performance and maneuverability of the vehicle itself. Therefore, the choice of power system (including engine and gearbox) is very important. High-performance powertrain scheme should be given priority, and advanced electronic control technology should be combined to achieve accurate adjustment to improve acceleration and ride comfort.

4. Special functional parts

In addition to the above-mentioned basic elements, there are also some functional components specially customized to meet fire fighting operations, such as high-pressure water pumps and automatic spraying devices. These devices are usually provided by professional suppliers, but manufacturers need to ensure that they can be perfectly integrated into the whole system and have good reliability and maintainability.

In a word, as a special special vehicle, fire truck must be strictly implemented in accordance with national standards or international certification system in every step from material selection to assembly in its manufacturing process. Only in this way can we create products that meet the actual needs and ensure the safety of users' lives and property. With the progress of science and technology and the development of society, more innovative technologies and design concepts will be applied to this field in the future, contributing to improving the fire safety level in China and even around the world.
