A vehicle steering knuckle integrally formed with a steering arm and a machining process thereof. The steering knuckle comprises a rod portion (1), a plate portion (2), and a lug portion (3). The lug portion (3) comprises a long lug (31) and a short lug (32). The long lug (31) and the short lug (32) are each provided with a main pin hole (4). A steering arm (6) connected to a steering tie rod extends laterally from a front end of the short lug (32) on a plane perpendicular to the main pin hole (4). The steering knuckle is integrally forged. During machining, the lug portion is first machined to form two long straight arms. Since the lug portion does not have any other connecting arm, the structure is simple and easily forged. Afterwards, one of the long straight arms is bent into the steering arm to reduce forging difficulty. The invention is structurally sound. The steering arm is extended in order to connect to other components, thereby simplifying the structure of a vehicle steering system, and resulting in a novel, lightweight steering knuckle.
