Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.

[0029] like figure 1 , figure 2 , image 3 , Figure 4 As shown, the automobile steering knuckle integrally formed with the steering arm in this embodiment includes a rod portion 1, a disc portion 2, and an ear portion 3. The ear portion 3 includes a long ear 31 and a short ear 32. The long ear 31 The short ears 32 are respectively provided with kingpin holes 4, and the front ends of the long ears 31 are elongated along the axial direction of the rod part 1 to form a tie rod arm 5 for connecting with the straight steering rod. The front ends of the short ears 32 are connected with the kingpin holes 4. A steering arm 6 protruding sideways on a vertical plane for connecting with the steering tie rod, and the steering knuckle is integrally forged. like fi...

Abstract

The invention relates to the technical field of steering knuckles, in particular to an automobile steering knuckle integrally formed with a steering arm and a machining technology of such automobile steering knuckle. The automobile steering knuckle is integrally formed by forging and comprises a rod portion, a disk portion and a lug portion, the lug portion comprises a long lug and a short lug, each of the long lug and the short lug is provided with a main pin hole, and the front end of the short lug extends out of the side face on the plane perpendicular to the main pin hole to form the steering arm connected with a steering tie rod. The automobile steering knuckle has the advantages that the automobile steering knuckle is scientific in structure and can be connected with other parts by extension of the steering arm, so that an automobile steering system is structurally simplified, and the novel lightweight steering knuckle is obtained; during machining, the lug portion is simple in structure without other connecting arms and convenient to forge and is machined into two long straight arms firstly, and then one long straight arm is bent into the steering arm, so that forging difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile steering knuckles, in particular to an automobile steering knuckle integrally formed with a steering arm and its processing technology. Background technique [0002] Steering knuckle is one of the main parts of the car. It effectively connects the braking system, steering system and suspension system through multiple parts, and plays the dual task of steering and carrying. It is an important safety part of the car chassis. The steering knuckle makes the car run stably and transmits the driving direction sensitively. At the same time, it needs to bear the front load of the car, support and drive the front wheel to rotate around the kingpin to make the car turn. The steering knuckle is generally fork-shaped, including a rod part, an ear part, and a disc part. The ear part includes a long ear and a short ear, and the long ear and the short ear have kingpin holes for installing the kingpin. [000...
