  • Patent number: 5951195
    Abstract: In the ball pivot arrangement for a ball joint described in the specification, an essentially spherical upper region and an essentially bar-shaped lower region are joined by friction welding, the spherical region being capable of being mounted in a joint cup or joint socket to form a ball joint and the bar-shaped region constituting a joint rod. The costs involved in producing the ball pivot arrangement are reduced and the ball pivot arrangement is more effectively adaptable to different stresses because each of the components can be machined or hardened separately to provide required dimensions or hardness before assembly.
