International CV Joint |
CV joints like the international CV joint are standard component of vehicles utilizing front-wheel drive and four-wheel drive. CV joints are also known as homokinetic joints. As the name suggests, CV joints allow the constant velocity of the front wheels even though they change angles during steering. CV joints enable the drive shafts of the front wheel to deliver engine output at constant rate even the front wheels change angles during steering. Actually, it is not only speed that is kept constant by the CV joints; torque and power are also kept constant by the CV joints. A CV joint is attached to the drive shaft and to a portion of the hub of the front wheel.
A CV joint is comprised of four basic parts enclosed by a CV boot. The CV boot protects the joint from contamination such as dirt and moisture. Dirt and moisture can drastically affect the performance of the CV joint. The CV boot also keeps the lubricant intact by preventing it to spill while the CV joint is rotating. The CV joint basic parts include the driveshaft from the transmission; the steel balls that run in grooves in the dome; the cage that is splined to the driveshaft; and the spherical dome and outer driveshaft that are connected to the hub of the wheel.
When the automobile is running, the wheels are kept to the ground by the force of friction, more commonly known as traction. The weight of the vehicle is also contributory in maintaining traction. However, traction varies as the vehicle constantly shifts its center of gravity when encountering road bumps. Traction also varies in relation to the speed of the wheels. During steering traction is very important in the stability of the vehicle. If traction is lost, the vehicle may skid or roll over. Hence, it is important to maintain traction, especially when the vehicle is running at high speed. The CV joints help in maintaining traction by allowing the front wheels to maintain constant speed even during steering.
Constant velocity joints are typically trouble-free and very reliable. However, CV joints are not totally invulnerable to deterioration. Wear and partial seizure are the two most common causes of CV joint failure. Vibrations on the front wheels are signs of wear on the CV joints. The vibrations are caused by the imbalance wheel sped and alignment. Worn joints typically produce rhythmic clicking or cracking noise. On the other hand, partial seizure causes “pattering” sensation through the suspension. When it is time to replace the CV joints of your vehicle, you can rely on Parts Train to provide you with the best aftermarket replacement product.
