Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle chassis parts, and relates to an anti-impact chassis hydraulic device for high-strength vehicles. Background Technique

[0002] The high-strength vehicle chassis adopts advanced materials science and engineering technologies. It usually selects advanced materials such as high-strength alloy steel, aluminum alloy or composite materials. These materials have excellent mechanical properties and corrosion resistance, and can withstand greater loads without being easily deformed or damaged. As an important part of the vehicle, the design and manufacturing quality of the vehicle chassis are directly related to the overall performance and use safety of the vehicle. If the vehicle chassis cannot effectively resist impacts, a series of serious problems will occur. The damage of the chassis will directly affect the controllability and stability of the vehicle. Most of the existing anti-impact structures of high-strength vehicle chassis use buffer devices to only perform overall shock absorption on the vehicle chassis. However, if the chassis is subjected to a large impact, the relatively fragile front and rear axles of the chassis parts may generate a large impact, directly causing the front and rear axles to be directly stressed and fractured, which may damage key components such as the suspension system and the steering system, thereby affecting the handling performance and driving stability of the vehicle.
