Technical Field
The invention relates to the technical field of automobile part equipment, in particular to an aluminum alloy underframe structure.
Background
The automobile chassis consists of four parts, namely a transmission system, a running system, a steering system and a braking system. The chassis is used for supporting and mounting the automobile engine and all parts and assemblies thereof, forming the integral shape of the automobile and receiving the power of the engine to enable the automobile to move and ensure normal running.
With the more and more serious urban congestion, the research and development of urban light rails are urgent, and at present, most urban light rail vehicle bodies are made of stainless steel materials. The weight of the light rail is heavy, so that the weight of the vehicle body is increased, and the running speed of the light rail is influenced. Therefore, a light and modular vehicle body structure, especially an underframe structure of a vehicle body, is continuously designed, so that the safety of the vehicle is ensured while the weight is reduced.
In response to the above-mentioned need, an aluminum alloy underframe structure is now provided.
