  • Constant velocity universal joint having an improved cage design
    Patent number: 5609527
    Abstract: A cage for a constant velocity universal joint has an increase in the fracture strength of the cage and thus the torque capacity of the entire constant velocity universal joint. This is achieved in that the apertures for the windows in the cage at the circumferentially extending contact faces do not extend parallel to the central axis but contact a virtual sphere arranged at the point of intersection between the radial center plane of the cage and the joint axis. As a result, the webs of the cage comprise a larger cross-section and in consequence, its fracture strength is improved.
