Upper support structure of front shock absorber

The invention relates to an upper support structure of a front shock absorber. The upper support structure comprises two layers of iron sheet frameworks. The two layers of iron sheet frames are completely wrapped by vulcanized rubber in order to form an upper support structure body. An upper-layer iron sheet framework comprises an upper-layer iron sheet framework body. A lower-layer iron sheet framework comprises a lower-layer iron sheet framework body. Both the upper-layer iron sheet framework body and the lower-layer iron sheet framework body are circular-ring-shaped. The edge of an inner ring of the upper-layer iron sheet framework body is equipped with an upward upper flanging. The edge of an outer ring of the upper-layer iron sheet framework body is equipped with a downward lower flanging. Bottom rubber corresponding to the lower-layer iron sheet framework body contacts a plane bearing. The center of the interior of the upper support structure is in rivet joint with an upper innercore steel jacket and a
