Beschreibung
Zusammenfassung:	The utility model relates to the technical field of automobile parts, in particular to a light composite brake drum which comprises an outer-layer steel shell and an inner-layer wear-resistant layer, the inner-layer wear-resistant layer is embedded in the outer-layer steel shell, and the thickness range of the outer-layer steel shell is 6-8 mm; and a limiting structure is arranged between the outer-layer steel shell and the inner-layer wear-resistant layer. The composite brake drum has the advantages that the thickness of the outer-layer steel shell of the composite brake drum is reduced, the mass of the brake drum is effectively reduced, the brake drum meets the lightweight requirement, the material consumption can be reduced when the thinned outer-layer steel shell is manufactured, and the manufacturing cost of the brake drum is reduced; meanwhile, the reinforcing structure is arranged on the outer-layer steel shell, so that the structural strength of the outer-layer steel shell can be enhanced, the brake d
