In the consumer aftermarket, these problems often occur with rack & pinion complete units.
1. Oil leakage;
2. Too tight meshing between the steering shaft sector teeth and the piston straight teeth, and lack of lubrication, etc., make it difficult to return;
3. Piston and cylinder are strained;
4. The sealing ring is damaged.
How do OnlyFaith’s rack & pinion complete units avoid these problems in the production and quality control process?
1. Designed and produced according to the original OE technology and quality standards, the aluminum shell is cast with a special mold, high-precision positioning, and the machining center is automatically processed to ensure the consistency of the parts;
2. The tooth part of the rack is processed by a forming knife to cut and shape at one time to ensure the accuracy of the parts. Tooth quenching adopts high-frequency quenching technology to ensure the consistency of hardness and high strength and wear resistance;
3. The gear material is made of high-strength 40Cr steel, which can withstand instantaneous strong impact and ensure safety. The tooth part adopts the post-fire precision rolling process to ensure the accuracy of the tooth profile and tooth direction;
4. The inner hole of the valve sleeve adopts eight-station reaming and honing to ensure the cylindricity of the inner hole;
5. The small plane of the valve core adopts color image microanalysis and optical projection magnification technology to ensure the indexing accuracy and error accuracy of each oil tank;
6. The torsion bar adopts 50CrVA material, which can guarantee 100,000 times of torsion fatigue test;

7. The regulating valve adopts the domestic advanced centering drilling and selling machine, and the assembly test adopts the most advanced domestic steering gear special testing equipment.
