Using Constant Velocity Joints To Improve torque And Efficiency

A Constant Velocity Joint is an articulating device used in modern day vehicles for connecting one side of a CV joint to another. CVJ's are often used for sealing joints in engines to ensure there are no leaks. Constant velocity joints (CVJ's) are also used on all-season vehicle and four-wheel drive applications. The joint is designed with a ball and socket design that allows a greater degree of mobility than other types of CV joint designs. Its primary function is to transmit torque from the engine to the wheels via a transfer case.

In a u-joint, the angle of rotation of the center joint rotates between the driveshaft and the pinion. The driveshaft provides the power for the axle and pinion while the pinion drives the bearing and the shaft through the center joint. A constant velocity joint is designed to withstand tremendous torque, so it is important to note that such a joint will be limited by the available transmission speed and the axial tilt. Constant-velocity (CVJ) joints are typically used in high-performance applications such as truck bodies and transmissions.

There are a number of advantages to using a Constant-Voltage Joint, including improved reliability, reduced weight, lessened parts dependence, improved wear resistance, lessened axle shaft movement, and improved consistency and geometry. The concept behind a CVJ joint is two separate shafts, one running into the other through an interlocking opening. The inner race then connects these two shafts together. The concept is that the constant-velocity joints allow the axle shaft to move more realistically within the bore and stroke of the rotational joint.

There are several different types of CVJ joints available. The most common type joint is one-sided or sealed. These joints are designed to minimize wear and increase lubrication to reduce possible damage. They are often used for axial applications because they provide the least amount of axial movement possible with their design.

Other types of CV joints include ball joints and sealed ball joints. Ball joints are similar to ball and cylinder valves in that they are also used to maintain constant valve lift at all times and thus provide a source of low maintenance and increased efficiency. Sealant is added to ball joints to prevent hydrostatic pressure from building up between the balls. Sealed ball joints are known for their relative durability, especially when compared to ball joints that are not sealed. Sealants also improve lubrication, which allows smoother and easier operation.

Most performance vehicles have transaxles because of the extra torque they offer. Because of this, they require an efficient transfer gear, and the most efficient method for transferring torque is with CV joints. Because the inner and outer layers of the transaxle do not move, there is no need to transfer hydraulic fluid between the two pieces of metal. This means a shorter lifetime for both parts, as well as an increase in efficiency.
