The CV joints were made to solve the problems posed by universal joints, ie not allow the speed to be transmitted through them consistently, ie the input and output speed do not match perfectly, producing large amount of vibration .

Joint type discussed here is the union of two cardan so disrupting the turn one makes up for the other, producing a uniform speed transmission gives the car's wheels. Can be considered as two cardan shaft connected by a very short length. Añadidamente have a centering system consisting of a ball and a small area, so that it can slide along the driven shaft. At the other end of the bearing, ie the difference is coupled another sliding universal joint, or you can arrange a meeting desliazante Glaencer dipole. This system consists of a tripod to where they join the rollers which are housed in grooves of a cylindrical sleeve which can slide. Within the tripod is attached the shield and on his cap the planetarium, producing a slip joint. The bush together with the dust and capping using the system enclosure.

This type of joint is permanently greased and are all low volume they occupy. Its performance is very good and have very little friction with the sliding and these joints CV behaves as any kind of angle, with a high capacity to transmit power and energy efficient. They are called GI, it is always adjacent to the differential.

In vehicles with front wheel drive aforementioned board is often accompanied by a constant velocity joint Glaenzer-Spicer (GE for being next to the wheel) or Rzeppa type ball joint.
