Preferably, the ring flange is equipped with two installation mounting holes.
Preferably, the steering knuckle structure of car surface is coated with antifriction metal (AFM) coating.
Preferably, the spindle is comprised the following steps that using forging processing technology:
1) material tests:Component is carried out before blanking to material quickly to detect;
2) blanking:High-speed Sawing Machine is selected to carry out blanking, and using the cutting mode of rotational shear;
3) base is heated:Selection electric furnace carries out heating base to the material of cut-out;
4) vertical forging:Hotdie forging press is selected, using the technique stream of jumping-up, Closed Extrusion, blocking and open type finish-forging Cheng Jiagong, spindle basic forming;
5) trimming:Trimming is carried out according to the processing step of pressure position, dead axle and side processing to the spindle of basic forming Processing;
6) correct:The spindle that trimming has been handled is corrected, and by the spindle after correction in hopper Interior progress heap is cold;
7) it is heat-treated:Heating quenching processing is carried out to spindle of the heap after cold;
8) electroplate:Antifriction metal (AFM) coating is electroplated on the spindle top layer being heat-treated.
It is using the beneficial effect of above technical scheme:Structure of the present invention is a kind of steering knuckle structure of car and its processing work Traditional steering knuckle structure of car is optimized in skill, the steering knuckle structure of car, is more in line with the automotive engineering hair in modern times Exhibition trend, the processing technology have the following advantages that, 1) composition has been carried out to material quickly to detect, has avoided with unsuitable material It is processed;2) blanking employs High-speed Sawing Machine equipment, is more bonded the requirement to material cutting end face;3) forged and pressed using hot-die Power machine is forged and pressed, and one stroke of hotdie forging press completes a process, and reliable operation, production efficiency are high, are easily achieved certainly Dynamic metaplasia produces, is influenced small, forging quality stabilization by other factors;4) electroplating surface wear-proof technique coating is carried out, improves automobile The wearability of knuckle, so that the security of automobile is improved, in conclusion the steering knuckle structure of car is optimized and changes Into, using the processing technology produce spindle quality it is more stable, structure is more reliable.
