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.
Claims12
A method for producing a ball pivot arrangement for a ball joint having an essentially spherical region and an essentially bar-shaped region comprising friction-welding an essentially spherical element to an essentially bar-shaped element to form a ball pivot arrangement wherein each of the essentially spherical element and the essentially bar-shaped element have a centering bore and including the step of introducing a pin into the centering bores to position contact faces of the elements relative to each other during friction welding.
A ball pivot arrangement for a ball joint comprising an essentially spherical region capable of being mounted in a joint cup or joint socket to form a ball joint and an essentially bar-shaped region constituting a joint rod wherein the essentially spherical region has a first contact face and the essentially bar-shaped region a second contact face and the contact faces are friction-welded to each other and wherein the essentially spherical region and the essentially bar-shaped region each have a centering bore aligned with each other.
