Abstract
A ball cage for universal use both in a cross-groove type plunging constant velocity joint and in a cross-groove type fixed constant velocity joint has an external contour with sections of different curvature. Axial edge sections of the external contour are designed as spherical sections located on the circumference of an imaginary sphere, whereas a center section of the external contour located axially between the edge sections runs radially inside the diameter of the imaginary sphere.
Claims11
A ball cage for a cross-groove type plunging constant velocity joint or a cross-groove type fixed constant velocity joint, the ball cage comprising:
- an external contour with sections of different curvature;
- axial edge sections of the external contour each formed as spherical sections and located on a circumference of a first imaginary sphere;
- and
- a center section of the external contour, located axially between the edge sections, runs radially inside a diameter of the first imaginary sphere,
- wherein the edge sections each transition continuously into the center section through a gradually curved transition section, such that the edge sections each extend over an arc angle region having an arc length that is smaller than an arc length of an arc angle region of the transition section.
