Zusammenfassung: | The utility model discloses an annular reinforced composite brake drum, and relates to a brake drum. The annular reinforced composite brake drum comprises a drum body, and an outer surface of the drum body is provided with a plurality of annular ribs. When used, circumferential force born by the brake drum is distributed along directions of the annular ribs, the main stress is concentrated on the annular ribs, so that stress of an inner hole of the drum body can be largely reduced; and in addition, according to the annular ribs disposed on the outer surface of the drum body, intensity of the drum body can be improved, heat can be radiated, and the drum body is prevented from being cracked due to heating when braking for a long time. An end surface of each annular rib is of a double-peak-shaped structure, areas of stress and heat dissipation of the annular ribs can be increased, the stress of the inner hole of the drum body can be further reduced, and the effect of heat dissipation can also be improved. The annular ribs at the orifice of the drum body are embedded with an alloy steel belt so as to improve intensity of the orifice and prevent the orifice from being cracked, and the drum body is prevented from being stressed and cracked from an edge of the inner hole. The drum body is prepared by abrasion resistant materials, so that wear resistance and thermal conductivity can also be improved. The annular reinforced composite brake drum is simple in structure and easy to popularize and use. |
