The invention discloses a casting part used for an auxiliary frame, the auxiliary frame and a vehicle, the casting part comprises a base body beam, and a structural cavity is formed in the base body beam; the die-casting part is arranged on at least part of the periphery of the base body beam, and the die-casting part and the base body beam are cast into an integrated piece. According to the casting part, the structural cavity is formed in the base body beam, the base body beam is pre-embedded into the mold, and then the casting part is arranged on at least part of the periphery of the base body beam through the high-pressure aluminum casting technology, so that the hollow base body beam is embedded into the high-pressure aluminum casting auxiliary frame, and a hollow structure is arranged on the high-pressure aluminum casting auxiliary frame; therefore, the structural strength and rigidity of the auxiliary frame are improved, and the NVH (noise, vibration and sound and vibration roughness) performance of the auxiliary frame is effectively improved.

    本发明公开了一种用于副车架的铸造件、副车架及车辆,铸造件包括:基体梁,所述基体梁内部形成有结构空腔;压铸部,所述压铸部设置于所述基体梁的至少部分外周并与所述基体梁铸造为一体件。根据本发明的铸造件通过在基体梁内部设置结构空腔,并将基体梁预埋进模具中,再通过高压铸铝技术将铸造部设置于基体梁的至少部分外周,使得在高压铸铝副车架上嵌入了空心基体梁,实现了在高压铸铝副车架上设置空心结构,从而提高了副车架的结构强度和刚度,有效改善了副车架的NVH(噪声、振动与声振粗糙度)性能。
