Constant-velocity Joint - The First CV Joints

The First CV Joints

As front wheel drive systems became more popular, with cars such as the BMC Mini using compact transverse engine layouts, the shortcomings of universal joints in front axles became more and more apparent. Based on a design by Alfred H. Rzeppa which was filed for patent in 1927 (a CV joint, the Tracta joint, designed by Pierre Fenaille at Jean-Albert Grégoire's Tracta company was filed for patent in 1926), constant velocity joints solved many of these problems. They allowed a smooth transfer of power despite the wide range of angles through which they were bent.
