Reasons for oil leakage in a steering gear:

Wear of steering gear seal: The seal may wear and age after prolonged use, leading to oil leakage.
Loose or damaged steering pipeline: Loose or damaged connection of steering pipeline may cause oil leakage.
The steering gear is defective: A design or manufacturing defect of the steering gear may also lead to oil leakage.

Solutions to oil leakage of the steering gear:

Check and replace the sealing components of the steering gear: If any sealing component is found to be worn or aged, replace it in a timely manner to solve the oil leakage problem.
Check and repair the steering pipeline: Check if the connection of the steering pipeline is loose or damaged. Repair or replace it if necessary.
Replace the steering gear: If it is discovered that the steering gear has a defect that cannot be repaired, the whole steering gear should be replaced.

Advantages of vika steering gear assembly

1. Shell:
Material: ZL111 aluminum alloy
Performance: The alloy features excellent casting performance. It is not prone to hot cracking, and has less wire shrinkage and high air tightness.
Appearance: There are no burrs. The surface is smooth and beautiful with precise threads.
2. Valve core:
Material: 40Cr
Process: It is processed with a machining center, leading to high precision, good product quality, and accurate valve core size.
Performance: Thanks to the high surface precision, the product operates smoothly and is highly resistant to oil leakage.
3. Gear:
Material: 40Cr
Process: The interior of the material is inspected through magnetic flaw detection to eliminate defects such as cracks after quenching to ensure high quality of the product.
Performance: The gear surface is sandblasted to improve its mechanical properties
4. Valve sleeve
Material: 45# steel
Equipment: Grooving machine (the internal arc grooves of the valve sleeve are processed with a grooving method)
Process:
High hardness is achieved through high-frequency quenching.
The inner hole is subject to three processes of honing, meeting internal roundness and roughness requirements.
Post-processing burrs are removed by means of surface sandblasting.
Performance: High internal cleanliness of the product, smooth oil circuit, and precise void angle and size are ensured, leading to accurate steering assistance time.
5. Oil seal: Japan-based NOK is a pioneer and contributor to the world's sealing industry. As one of the earliest companies in Japan to produce oil seals, it provides leading-edge technology and production equipment to ensure high oil resistance and sealing performance of oil seals.
6. Rack:
Material: 40Cr
Process: Thanks to multiple alignment steps, the rack provides high straightness, and consequently the steering gear operates reliably.
Equipment: A universal milling machine with a lifting table and a holistic cutter are used for one-time milling of teeth. They ensure consistent tooth pitch.
Performance: Due to the high product processing precision, the steering operation is smooth with less steering wear.
