Drive shaft assembly is an important component in an automotive transmission system. It transmits engine power from the transmission to the front wheels, and enables the car to run at high speeds.
A drive shaft assembly should be replaced in the following circumstances:
1. Broken or damaged shaft: If the shaft of the drive shaft assembly is broken or damaged, and cannot be repaired or still has a safety hazard after repair, the assembly should be preferably replaced. A broken or damaged shaft may cause the car to lose driving force or prevent it from running normally.
2. Damaged transmission gear: If the transmission gear of the drive shaft assembly is severely damaged, and cannot be repaired or fails to function normally after repair, the assembly should be preferably replaced. A damaged transmission gear may prevent normal transmission of power to the wheels.
3. Bearing failure: If the bearing of the drive shaft assembly has failures such as excessive wear, damage, or looseness, and cannot be repaired or fails to function normally after repair, the assembly should be preferably replaced. Bearing failure may result in problems such as jittering, vibration, or abnormal noise during drives.
4. Rubber sleeve aging or damage: If the rubber sleeve of the drive shaft assembly exhibits severe aging, damage, or oil leakage, and cannot be repaired or fails to provide adequate sealing performance after repair, the assembly should be preferably replaced. An aged or damaged rubber sleeve may cause leakage of lubricating oil or penetration of dust into the assembly, thereby interfering with its normal operation.
Solutions to a drive shaft assembly failure:
1. Inspection and repair: Thorough inspection should be performed first to determine the specific cause of the drive shaft assembly failure. Diagnosis by a professional automotive repair technician may be required. Once the cause is found, an attempt can be made to repair the assembly by replacing damaged parts, repairing broken or damaged shafts, or lubricating and adjusting the parts.
2. Replacement of the drive shaft assembly: If the drive shaft assembly is severely damaged or cannot be repaired, it may be necessary to replace it completely. To achieve this, a brand new drive shaft assembly should be bought and installed on the car. Replacing the drive shaft assembly necessitates specialized techniques and tools, and should be performed by professional automotive repair personnel preferably.
3. Regular servicing and maintenance: Regular maintenance and servicing is critical for avoiding failures of the drive shaft assembly. Such operations may include regularly changing lubricating oil, checking and tightening the bolts of the drive shaft assembly, and checking the wear of the rubber sleeve and bearing. Following the manufacturer’s recommendations and maintenance schedule can help extend the service life of the drive shaft assembly and reduce the risk of failure.
The vika drive shaft assembly complies with GB/T 10189–2010 industrial quality standard, and the entire production process is fully in accordance with the TS9000 system, thus ensuring more stable product performance. In addition, an “electrostatic powder spraying” protective treatment process in line with EU standards is adopted to achieve better environmental protection effect.
Advantages of vika drive shaft assembly:
Inner and outer ball cages: The inner and outer ball cages of vika are made of 55# steel. They are cast through cold extrusion and warm forging processes that lead to high hardness. The groove adopts a double-arc contact design, and the cage and star inner wheel are made of 20CrMnTi, with hardness as high as HRC 58–62 after tempering.
Dustcover: Dustcover creates a sealed environment for the inner and outer cavities of the ball cages, preventing ingress of foreign objects and leakage of lubricating oil. The dustcover of vika drive shaft assembly is made of neoprene, which is resistant to extreme temperatures in the range of -40°C to 130°C and leads to a service life three times that of rubber dustcover.
Steel ball: The vika drive shaft assembly uses OEM steel balls that are produced in strict accordance with OE standard, ensuring consistent size of the steel balls on each cage.
Clamp: The vika drive shaft assembly clamp is a product from OEM supplier OETlKER (№1 brand globally). Both sides of the clamp are deburred and rounded to minimize damage to the dustcover.
Lubricant: The molybdenum disulfide (MoS2) content in the vika drive shaft assembly lubricating oil is higher than 2.5%, which results in excellent resistance to wear and extreme temperatures, and ensures normal operation of the ball cage shaft under high-speed conditions for long.
