Abstract
In a constant velocity joint, the inner running grooves start from a first end of the inner part and extend along the entire length of the inner part as far as a second end. The inner running grooves are open toward the second end, and toward a central recess which starts from the second end. The central recess provides a lubricant groove function. Further, the inner running grooves preferably have a first portion and a second portion. The first portion serves to receive an associated ball extending through a cage and into the outer part. The second portion also provides a lubricating function.
Claims6
A constant velocity joint comprising:
- an outer joint part with a cavity having an inner face provided with outer running grooves arranged in meridian planes relative to a longitudinal outer part axis;
- an inner part arranged in said cavity of said outer part and which at an outer face, has inner running grooves which, in accordance with said outer running grooves are circumferentially distributed in meridian planes around a longitudinal inner part axis, with one portion of said outer face being provided in the form of a spherical bearing face;
- a hollow cage with a hollow spherical partial face for being slidingly supported on said spherical bearing face of said inner part and which has radially open windows;
- a plurality of balls with one of said balls received in each said window of said cage and projecting outwardly into an outer running groove and inwardly into an inner running groove;
- and
- said inner running grooves start from a first end of said inner part, extend along the entire length of said inner part as far as a second end and are open towards said second end and towards a central recess which starts from said second end and wherein said inner running grooves starting from said first end, serve only along a first portion as running grooves for an associated ball.
