Abstract

Constant-velocity fixed joints may comprise an outer joint part with outer ball tracks, an inner joint part with inner ball tracks, torque transmitting balls which are guided in pairs of tracks each formed of an outer and an inner ball track, and a ball cage with circumferentially distributed cage windows in which the balls are received. Here, the balls are held in a common central plane and are guided onto the bisecting plane when the joint is deflected. Constant-velocity rotary joints of this type are known as Rzeppa fixed joints (RF) or as undercut-free fixed joints (UF).
