Description

Technical field

[0001] The invention relates to the technical field of auto parts, in particular to design an upper swing arm assembly of an automobile. Background technique

[0002] The upper swing arm assembly has the function of guiding and supporting the suspension, and its deformation will affect the wheel positioning and reduce the driving stability. If there is a problem with the upper swing arm assembly, you will feel the steering wheel shaking, and after the hand releases the steering wheel, the vehicle is easy to run off, and it is difficult to grasp the direction at high speed.

[0003] The upper swing arm assembly has complex structure, high product technology content, difficult production technology, and under the condition of a million times of large load impacts, the safety and reliability meet the requirements of 100%, and the physical strength is high, bending deformation, earthquake resistance, and wear resistance. Parts.

[0004] The structural rigidity, strength...
