Abstract:
1. A constant velocity joint, comprising: an outer joint part; a ball cage containing one ball in each of a plurality of circumferentially spaced windows in said cage, said ball cage having a first inner partial spherical surface facing a front opening of said cage defined by a first radius having a center offset from a ball center, a second inner partial spherical surface facing a rear opening of the cage defined by a second radius extending from the same center offset from said ball center, wherein said first radius is smaller than said second radius, and a single transition section between said partial spherical surfaces of said ball cage; an inner joint part having a first partial spherical surface facing a front opening of said cage, a second partial spherical surface facing a rear opening of said cage and a single transition section between said partial spherical surfaces of said inner joint part; wherein said ball cage spherical surfaces and said inner race spherical surfaces define between them an open space having a predetermined length defined by the overlap of said first inner partial spherical surface of said ball cage and said first partial spherical surface of said inner joint part.
