The Constant Velocity Joint (CVJ) is a very important element in the automotive drive train system. There are various types of CVJs, both “fixed” and “plunging”. Each CVJ consists of several parts and these move in 3-dimensions as they rotate and transmit torque. Investigations of the motion and dynamic forces generated on these parts are important in the development of a CVJ. Various experimental methods for measuring the motion and forces of a CVJ were investigated. It is very difficult to measure these parameters directly. Because of advancements in computer technology, Computer Aided Engineering (CAE) offers major advantages to the design and development of the automotive industry. By using CAE, it is possible to correctly investigate the motion and forces generated on CVJ internal parts. This paper describes analytical results of dynamic forces that are generated on inner parts of a type of plunging CVJ called a Double Offset Joint (DOJ) using the ADAMS dynamic modeling software.

Packaging constraints and environmental concerns have increased the demand for automotive components with reduced weight, better performance, and higher efficiency. To meet these demands, research and analysis of mechanisms, materials, and lubrication has led to the development of the next generation of constant velocity joints (CVJ) – the EBJ, a reduced weight, compact, high performance ball fixed constant velocity joint. This paper compares some of the features and functional test results of the EBJ and conventional Ball Fixed Joint (BJ) designs.

The demand for reducing noise levels in today's vehicles has increased. This is especially true for four wheel drive vehicles that have complex drivetrain systems. To date, Cardan Joints (CJ) are the most commonly used joints in four wheel drive vehicle propeller shaft applications. CJ's have many NVH concerns, even when the driven and driving angles are equal. Constant velocity joints (CVJ) can solve many NVH concerns, and provide better performance in propeller shaft applications. Since the rise of vehicle ride standards; CVJ's have been replacing Cardan Joints (CJ's) used in propeller shaft applications. This paper compares some of the features and functional test results of CJ's and CVJ's as they apply to propeller shaft applications.
