  • Light articulation ball-joint and method of manufacture of such a ball joint
    Patent number: 7845875
    Abstract: The light articulation ball-joint comprises a metal inner ring and a metal outer ring, provided respectively with a spherical outer surface and a spherical inner surface. The ball-joint also comprises a first contact layer, applied to the spherical surface of one of the rings, and a second contact layer, applied to the spherical surface of the other ring. According to the invention, the first contact layer has a hardness which is less than the hardness of the second contact layer and a thickness which is greater than the thickness of the second contact layer, the first contact layer further being adapted to release particles of solid lubricant by friction with the second contact layer.
