A large bent arm part used for an automobile chassis comprises a rod-shaped connection arm body. At least one arch bent section is manufactured at the two ends of the connection arm body according to the positions of connection parts at the two ends. A short cylindrical connection block is arranged at one end of the connection arm body. A connection through hole is formed in the middle of the connection arm body. A bowl-shaped connection block is arranged at the other end of the connection arm body. A bowl-shaped groove is formed in the bowl-shaped connection block. The axis of the connection through hole is perpendicular to the axis of the bowl-shaped groove. A whole long rod of the connection arm body forms a twisted special shape. The short cylindrical connection block at one end and the bowl-shaped connection block at the other end oppositely form a twisted corner of 90 degrees in the same radial plane so that the axis of the connection through hole can be perpendicular to the axis of the bowl-shaped groove. The large bent arm part has the advantages of being simple and reasonable in structure, convenient and reliable to use, convenient to machine, high in strength and toughness, and the like.
