The invention discloses an automobile clutch cover assembly optimizing structure. According to the automobile clutch cover assembly optimizing structure, limiting ribs are arranged on the periphery of the inner side of a middle hole of a part of a clutch cover. By arranging the limiting ribs additionally on the periphery of the inner side of the middle hole of the part of an existing clutch cover, the problem that a driver blade is large in deformation (H) due to the fact that a pressure plate part moves downwards under a free (uninstalled) state is restrained, and therefore the plastic deformation of the driver blade is reduced effectively and the effect of protecting the driver blade is achieved. Meanwhile, the structure enables the separation of a small-size automobile clutch cover assembly to be smoother in a free (uninstalled) state, the rigidity of cover parts is improved, the deformation of the cover can be reduced, the structure is simple, manufacturability is good, and the driver ...
