They are mainly used in front wheel drive vehicles.

What is a cv joint in my car. Cv or constant velocity joints are an essential component of front wheel drive cars. However the joint itself is a weak point in the system. Updated august 29 2018.

The drive shaft is connected to an inner race. A rear wheel drive vehicle may have them too if it. Constant velocity joints allow a drive shaft to transmit power through a variable angle at constant rotational speed without an appreciable increase in friction or play.

A cage keeps the balls aligned in a circle on one plane. The flow of transmission power to the wheels is consistent with the rotational speed and there is very little friction. Another name for a transmission is a gearbox because it is comprised of gears that make the vehicle move a certain way.

When the transmission generates power the cv joints transfer this power to the wheels under the vehicle. They are built into the front axle of cars and on occasion can be found on rear axles as well. It s not uncommon to see a car with over 300 000 miles with still original cv joints.

In a front wheel drive car the axles are connected to the wheels with constant velocity cv joints. A cv joint is a constant velocity joint sometimes called a half axle or a homokinetic and it is part of a front wheel drive vehicle s assembly that helps transfer the power from the engine to the wheels while limiting the amount of friction. Modern rear wheel drive cars with independent rear suspension typically use cv joints at the ends of the rear axle halfshafts and increasingly use them on the drive shaft.

It needs lubrication and it needs to be protected from dirt dust rocks and other. Constant velocity joints are protected by a rubber boot a cv gaiter usually filled with molybdenum d. Rear wheel drive vehicles can also have cv joints on the rear axle half shafts or the drive shaft.

The cv joint is made up of hardened steel and bathed in heavy lubricating grease. Most front wheel drive vehicles have cv joints in them. These joints are designed to be able to bend in any direction while continuing to turn the drive wheels at a constant velocity.

A ball type and a tripod type. These allow the axle and wheel to flex as the car drives to account for turns uneven surfaces and more. 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.

The cv joints are needed to transfer the torque from the transmission to the drive wheels at a constant speed while accommodating the up and down motion of the suspension. A cv joint doesn t need any maintenance and can last very long as long as the protective cv joint boot is not damaged. Constant velocity joints also known as cv joints assist in transferring transmission power to the wheels underneath the vehicle.

Constant velocity joints better known as cv joints are components of the drivetrain in any modern vehicle. They are primarily used in the drive shafts of front wheel drive cars. There are two most commonly used types of cv joints.

Most cv joints feature six hardened steel balls which ride in grooves in the inner race. A cv joint is packed with a special grease and sealed tight with the rubber or plastic boot that is held in place with two clamps.
