  Shield for use in a constant velocity joint - Patent 6579187
To achieve this protection the constant velocity joint is usually enclosed at the open end of the outer case by a sealing boot made of a rubber, thermoplastic or silicone.
The constant velocity joints 10 may be any of the standard types known such as a plunging tripod, cross groove joint, fixed joint, a fixed tripod joint, or double offset joints, all of which are commonly known terms in the art for different varieties of constant velocity joints.
The constant velocity joint 10 is a fixed constant velocity joint which is generally used in the prop shaft 26 in an all wheel drive vehicle.

 Tips - Constant Velocity Universal Joints
A constant velocity universal joint transmits a smooth rotation from a drivlng shaft to a driyen shaft at any working angle without the usual speeding up and slowing down action that is customary in a shaft driven by a universal Joint of the simple, pin, yoke, or spider type.
Constant velocity universal joint’s are of either the disk or the bell type.
Constant velocity joints are particularly useful in all types of motor vehicles, from, the lightest passenger car to the heaviest truck.

 Constant-velocity joint - Wikipedia, the free encyclopedia
Driveshafts using CV joints are self-supporting along their length, and do not need additional supports (although very long shafts such as the right-hand driveshaft on the Citroën CX or Peugeot 205 have an intermediate bearing that supports the inboard joint).
The end of the driveshaft (1) is splined which fits into the outer "joint" (4) and is typically held in place by a circlip.
Constant velocity joints are usually reliable and largely trouble-free.

 B274
The difference between a constant velocity joint and a Universal joint is in the theory of operation.
When a second joint is put in phase with the first joint, the velocity change is countered from joint to joint so the input speed at the first joint will be the same as the output speed after the second joint.
Constant velocity joints are usually much larger than the equivalent universal joint and are generally used in the automotive industry, not in industrial applications.

 What is a CV Joint?
A CV joint, or constant velocity joint, is part of a drive shaft, the shaft that attaches to a car's transmission at one end and the wheel at the other.
CV joints are designed to be able to bend in any direction while continuing to turn the drive wheels at a constant velocity.
The CV joint is used in front wheel drive cars because of its ability to maintain a constant drive force to the wheels despite the many different kinds of movements in the front end of the car.

 CV joint (Constant Velocity joint) - Vehicle Terms, Parts and Abbreviations
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.
rear wheel drive cars with equipped with independent rear suspension typically use CV joints at the ends of the rear axle halfshafts.
AWD (all wheel drive) vehicles use them for all four half-axles and on the front-to-rear driveshaft (propeller shaft) as well.

 Constant Velocity Joint Maintenance   (Site not responding. Last check: 2007-10-18)
A Constant Velocity, or "CV" joint is a special type of flexible couple that allows a shaft to rotate at a fixed speed regardless of the angle at which it is bent.
While CV joints are extremely effective in maintaining constant velocity during extreme angles, they are vulnerable to premature failure if exposed to dirt or moisture.
For that reason, constant velocity joints are protected with an accordion rubber boot that permits free movement but keeps the elements out.

 Universal joint - Wikipedia, the free encyclopedia
In Europe, the device is often called the Cardan joint or Cardan shaft.
To prevent the jerky rotation of the axle or driven shaft there usually are two U-joints in a three part shaft assembly.
The second U-joint will convert the jerky movement back to an even, uniform speed of the third shaft - if both the driving and the driven shaft are parallel and the two universal joints are correctly aligned with each other.
