Slight oil leakage of a shock absorber should not be ignored. If a shock absorber of a car has oil leakage, it may be dangerous. Although the leaky shock absorber does not interfere with driving, the lack of damping of the shock absorber will reduce comfort, and may cause stability problems at high speeds.
The shock absorber is not an enclosed cylinder. The hydraulic oil in it is sealed by a rubber sealing ring. Pressure impact for a long time can cause the hydraulic oil to seep out of the sealing ring, which is known as shock absorber oil leakage. Such leakage is a very slow process, and will only affect driving experience when it reaches a certain degree. Slight oil leakage typically does not interfere with operation of the car.
The shock absorber is a large part on the suspension that helps support the weight of the vehicle body. It plays a more important role in improving driving smoothness and comfort. Because the hydraulic unit in the shock absorber column can significantly absorb the vehicle body vibration on uneven road surfaces, it great reduces the bumps during drives. In simple terms, a car may experience ten bumps due to vibration without a shock absorber in a road section, but may only experience two bumps before realizing smooth driving with the help of a shock absorber. Therefore, shock absorption has important implications for vehicle comfort.
Advantages of vika shock absorber:
1. Appearance: The vika shock absorber is based on a fully automatic mechanical welding process, which leads to more elegant appearance and more robust structure due to small weld joints and constant welding temperature, angle, and time. It is equipped with dust cover clips to achieve closer matching with the dust cover.
2. Piston rod:
Material: standard 45# steel
Process: mechanical processing (precision grinding) — high-frequency quenching — surface chromium plating
Performance: longer service life of the product (without oil leakage after long use)
3. Work cylinder: The work cylinder makes use of high-precision pipes (cold-drawn seamless steel pipes) with high internal surface processing accuracy.
4. Valve body: A self-locking nut process is adopted for the vika shock absorber to keep the nut firm and prevent loosening. Consistent valve body damping force is therefore guaranteed for long.
5. Piston: The piston structure is well designed to ensure close contact between the piston and the working cylinder wall, eliminate oil leakage between them, and realize consistent damping force.
6. Valve plate: The vika shock absorber is produced with the most advanced process, which leads to more compact structure. The damping force is adjusted by changing the liquid flow rate and valve plate opening angle. This design is more stable and features a longer service life.
7. Oil seal: The vika shock absorber adopts world-class NOK oil seals that reduce friction between the piston rod and the oil seal and extend the lifespan of the seals and the product. The multi-lip oil seal design can effectively seal oil and high-pressure nitrogen, prevent ingress of external dust and dirt, and ensure high product quality and long lifespan.
8. Shock absorber oil: High-performance shock absorber oil is used, which provides good foam resistance and shear resistance, reduces idle travel of the product and wear of internal valve parts, and leads to a long service life. With excellent temperature/viscosity performance, the vika shock absorber is suitable for vehicles running in different regions and climatic conditions.
