The invention belongs to the technical field of automobile parts, and discloses a hollow cast aluminum steering knuckle and a suspension.The hollow cast aluminum steering knuckle comprises a steering knuckle body and a mold core assembly, the steering knuckle body is provided with a hollow cavity, and a first mold core piece and a second mold core piece are connected in a buckled mode and located in the hollow cavity, namely, the mold core assembly is embedded in the aluminum steering knuckle body; the first mold core part and the second mold core part are both of a hollow structure, the aluminum size and the weight can be effectively reduced, the mold core assembly is made of metal materials, the heat conductivity of the mold core assembly is better than that of sand mold and foam mold cores, the defect of internal shrinkage porosity of the steering knuckle body is reduced, and the phenomena of heating and gas generation cannot occur in the casting process; therefore, the shrinkage cavity defect in the steering knuckle body is reduced, the performance of materials is improved, meanwhile, harmful gas cannot be generated in the casting process of the mold core assembly, the mold core assembly and the steering knuckle body are embedded into a whole, connection is reliable, supporting is formed in the hollow cavity, and the structural strength of cast parts can be improved.

    本发明属于汽车零部件技术领域,公开了空心铸铝转向节及悬架,该空心铸铝转向节包括转向节本体和型芯组件,转向节本体设置有空心腔,第一型芯件与第二型芯件对扣连接并位于空心腔内,即型芯组件镶嵌在铝制转向节本体内,第一型芯件和第二型芯件均为空心结构,可以有效降低铝体积和减重,型芯组件由金属材料制成,其导热性优于砂型和泡沫型型芯,使得转向节本体的内部缩松的缺陷减少,并且在铸造过程中不会出现发热和发气的现象,从而使得转向节本体内部的缩孔缺陷减少,有助于提高材料的性能,同时,型芯组件在铸造过程中不会产生有害气体,并且与转向节本体镶嵌为一体,连接可靠,在空心腔中形成支撑,可以提高铸造零件的结构强度。
