Automobile parts and automobile manufacturing



With the rapid development of science and technology, the automobile industry is developing at an unprecedented speed. From the initial carriage to the modern intelligent electric vehicle, every technological innovation has brought earth-shaking changes to our lives. Among them, the design and production of auto parts and the progress of vehicle assembly technology have played a vital role.

I. Automobile parts

1. Engine

The engine is the heart of the car, which is responsible for converting the energy generated by fuel combustion into mechanical energy to drive the car forward. According to different working principles, it can be divided into two categories: gasoline engine and diesel engine; According to the arrangement of cylinders, it can be divided into in-line type, V-type and horizontally opposed type. In recent years, hybrid power system and pure electric drive system have gradually become one of the mainstream choices in the market.

2. Chassis

The chassis includes suspension device, steering mechanism, braking system and other subsystems, which together ensure the stability and safety of the car during driving. In addition, the application of lightweight materials makes modern models more energy-saving and environmentally friendly.

3. Body structure

The car body is not only related to aesthetics, but also bears the important responsibility of protecting the safety of passengers. High-strength steel or aluminum alloy is widely used to make anti-collision beams to enhance the living space during collision. At the same time, reasonable internal layout design is also one of the key factors to improve ride comfort.

Second, automobile manufacturing

1. Modular production

Modularization refers to the process of decomposing complex products into several relatively independent functional units that can cooperate with each other for processing and assembly. This method greatly improves the production efficiency and reduces the cost. For example, Volkswagen Group has adopted MQB platform to achieve versatility and flexibility among various models.

2. Automated production line

The application of automation technology makes the whole manufacturing process more efficient and accurate. Robots can play an important role in welding, spraying, testing and other links. After setting parameters by pre-programming, they can quickly and accurately complete the specified tasks, reduce the possibility of human error, and help to ensure the consistency of product quality.

3. Lean management

Lean thinking emphasizes eliminating waste, continuous improvement and maximizing value. In the automobile manufacturing industry, it is manifested in shortening delivery time, reducing inventory backlog and optimizing resource allocation. Enterprises usually use JIT(Just-In-Time) real-time supply system to reduce raw material reserves and improve capital turnover.

In short, in today's increasingly fierce global competition, how to use advanced technology and scientific methods to improve product performance and reduce costs has become a key issue of concern to all car companies. In the future, with the development and application of new materials and new energy technologies and the continuous improvement of intelligent level, I believe we will usher in a new era of more environmental protection, energy saving, convenient and efficient travel.
