- an annular housing having a first end portion, a second end portion, and a cylindrical inner surface defining a bore extending from said first end portion to said second end portion, said first end portion including an end surface extending radially relative to said cylindrical inner surface, said second end portion of said housing including an annular projection extending radially inward from said cylindrical inner surface of said housing;
- a plastic ball socket arranged within said bore in said housing, said ball socket having an opening on a first axial end and being closed on a second axial end, said first axial end of said ball socket adjoining said first end portion of said housing and said second axial end of said ball socket adjoining said second end portion of said housing, said ball socket including an extension projecting axially beyond said first end portion of said housing and radially overlying said end surface of said first end portion of said housing, said extension including a first annular groove facing said end surface of said first end portion of said housing,
- said ball socket including a cylindrical outer surface extending parallel to said cylindrical inner surface of said housing, said ball socket further including a second annular groove adjacent said second axial end of said ball socket, said second annular groove being defined by first and second radially extending surfaces and an axial surface extending parallel to said outer surface between said radially extending surfaces,
- said annular projection at said second end portion of said housing extending into said second annular groove in said ball socket to secure said ball socket in said housing;
- a ball arranged on a gudgeon and located in said ball socket, said ball being rotatable and tiltable relative to said ball socket; and
- a sealing bellows arranged between said housing and said gudgeon for sealing said opening in said first axial end of said ball socket, said sealing bellows having an annular lip received in said first annular groove in said extension of said ball socket, said sealing bellows being clamped between said end surface in said first end portion of said housing and said extension on said ball socket to secure said sealing bellows to said housing.
- 2. The ball joint of claim 1 wherein said ball socket further includes a shoulder at said first axial end and which interconnects said outer surface with said extension of said ball socket, said ball socket being fixed axially at said first axial end portion of said housing by said shoulder.
- 3. The ball joint of claim 2 wherein said shoulder comprises a slanted annular surface.
