Patent ID: 8231475

Claim:
Constant velocity pivot joint, comprising a) an outer joint part with three guideways distributed over the circumference and extending in the axial direction, b) an inner joint part with three pivot pins, which are distributed over the circumference and extend in the radial direction, and which are provided to come into engagement with the guideways, and which form roller bearing surfaces, c) and rollers disposed between the outer joint part and the inner joint part, each of the rollers comprising i) an inner ring with an inner roller surface, the shape of which is adapted to the roller bearing surfaces of the pivot pins in such a way that a pivot pin of the inner joint part inserted into the inner ring can execute a tilting movement therein, but not a linear displacing movement, ii) and an outer ring with an outer roller surface, the shape of which is adapted to the guideways of the outer joint part in such a way that an outer ring inserted into a guideway can execute a roll-off movement therein, iii) a plurality of rolling members being disposed between the inner ring and the outer ring so that the outer ring can roll off on the inner ring, iv) the inner ring forming an axial guide, which fixes the position of the rolling members relative to the inner ring in the axial direction, v) the inner ring and the outer ring being axially displaceable relative to each other, wherein vi) the outer ring forms an inner displacement stop and an outer displacement stop which extend in the radial direction inwardly and which limit the roll-off movement of the rolling members on the inner surface of the outer ring in the axial direction, and vii) a displacement stop does not reach over the outer contour of the inner ring.
