Chassis systemIncluding subsystems such as suspension, braking and steering, which traditionally affect the comfort, safety and handling of the entire vehicle, the impact on new energy vehicles is even more profound.

The overall requirements for new materials, new processes and stability of chassis parts

Lightweight and new materials

In the future, the use of aluminum alloy chassis in automotive chassis will become increasingly widespread. The demand for magnesium alloys is also on the rise. However, we should also constantly study some new designs to meet the demands of light automotive parts.

Stability

The stability of the chassis components is the foundation of a car's safety. To achieve properties such as strength, flexibility, fatigue resistance and damage resistance, the application of pipe hydraulic forming technology will become increasingly frequent, and pressure processing technology will develop towards high efficiency, automatic weight reduction of vehicles and cost reduction.

Casting

Chassis castings are developing towards high performance, thin walls, light weight, precise (accurate) dimensions and excellent cutting performance. The casting production process is developing towards a green casting direction that is clean, waste-recycled, efficient, energy-saving, material-saving and environmentally friendly.

Mechanical processing

Efficiency, precision, flexibility and automation will be the main trends of future development. High-speed processing technology, agile manufacturing technology, intelligent processing technology, green processing technology, etc. will all develop rapidly.

Surface treatment

The protective electroplating of automotive parts has evolved from the original single galvanizing passivation process to zinc alloy coatings with good corrosion resistance, low heat resistance, low hydrogen embrittlement, good processing performance and good environmental protection performance, as well as chromium-free dacromet processes. While significantly enhancing the corrosion resistance of the coating, the forward coating also features good heat resistance and a low coefficient of friction.

Environmental protection requirements

In the field of chassis, environmentally friendly components such as low rolling resistance tires, green tires, lead-free wheel balance weights, six-stage chromium-free coating technology, and electric steering systems will become increasingly widespread in the near future.
