Motor cars ride and handling accuracy is usually transmission, suspension and wheel end systems together results. Most passenger cars are now front-wheel independent suspension system at the configuration, usually McPherson suspension or link suspension. Because both sides of the wheel can be relatively independent and to maintain contact with the ground, so the independent suspension system can provide a superior driving feel.
Constituted by a series of differential gear, can guarantee to provide for both sides of the wheel, while the output at different speeds, providing the same rotational torque. This effect is particularly evident in the vehicle when cornering. Usually when the vehicle turns, the outside wheels relative to the inside of the wheel will have longer travel path, if there is no differential exists at this time, may lead to the outside or the inside of the wheel drag wheels slip. When the driving wheel in the rotation when the Cage (CVJOINT, CVAXLE) can maintain a constant speed of vehicles on both sides of the wheel, while ensuring a different speed (usually greater than the inside of the outer wheel driving distance). Cage will also be changed by sliding the connector between the differential and the wheels of the vehicle due to the length of the suspension system to make up and down movement caused by compensation.
Although Cage joints very precise manufacturing process, but each year nearly 2% of the vehicles in a certain number of years, the side of the axle or CV joint failure. In Europe alone there are nearly 400 million vehicles each year encounter such problems. Driving habits and road conditions that affect the life of two universal joints Cage factors, in addition, proper installation and maintenance procedures are also important. In strict accordance with manufacturer's requirements to operate, determine the maintenance of quality, and ultimately customer satisfaction.
Cage Universal Joint Failure Analysis
Cage joints in most cases is no failure, but outside the Cage wear under a certain speed will be displayed in the form of vibration.
Some failures may be due to dust jacket rupture Cage (CVJOINT, CVAXLE) oil spill caused by Cage temperature is too high. The end result is a suspension issued by ticking sound. If you can discover the problem, you can clean the joints and re-injected into the grease. Dust cover is replaced.
Cage the main cause of failure because the joints wear, part failures.
Check Cage joints: notch; dent; bump; the surface roughness.
