Invented and patented in the United States in 1926 by Alfred H. Rzeppa, the Rzeppa-type constant velocity joint represents the foundation of modern cage-type CV joint design and is widely used as the outer CV joint in passenger vehicles today.
CV Joint Inspection Challenges
Critical CV joint features—including concentricity and ball track geometry—directly impact performance and service life.
Standard measuring tools cannot reliably evaluate these features in mass production.
Process-oriented, dedicated gauges are essential for consistent quality control.
