Constant Velocity joint, used in drive-shafts where the input and output shaft must rotate smoothly at the same uniform speed of rotation.
a flexible coupling attached to a drive axle
a special joint on the front axle of a front wheel drive vehicle
a type of universal joint, usually used between the front half-shafts
Stands for "Constant Velocity" Joint. Type of universal joint in a halfshaft assembly in which the output shaft turns at a constant angular velocity without variation, provided that the speed of the input shaft is constant.
Also Constant Velocity joint. Found mostly in front-wheel-drive cars, and on some rear-wheel-drive cars with independent rear suspension systems, these special joints transmit engine power while allowing full steering and suspension movement. They are covered by black accordion boots that protect joints and hold grease.
