CV
Joint (Constant Velocity Joint)
CV
joints (Constant Velocity Joints) allow a rotating driveshaft
to transfer power through a variable angle, at constant rotational
speed, without an appreciable increase in friction or play,
freely allowing the wheel to move up and down with the suspension
and rotate about a vertical axis for steering. They are mainly
used in front wheel drive and all wheel drive cars. However, rear wheel drive cars with equipped with independent rear
suspension typically use CV joints at the ends of the rear
axle halfshafts. Some AWD (all wheel drive) vehicles use them for all four half-axles
and on the front-to-rear driveshaft (propeller shaft) as well.
