Abstract
To improve the corrosion protection at the connection site of the sealing cuff and the ball pivot, a ball joint with a sealing cuff (7), made of an elastically deformable material, is proposed, which is connected, with an edge profile (9), to a ball pivot (2) in a positive-locking manner in the direction of rotation around the longitudinal axis of the ball pivot (2) and has an elasticity that compensates for the maximum rotary and swiveling movements of the ball pivot (2) relative to the housing (1).
Claims12
A ball joint for motor vehicles, comprising:
- a housing having an outer circumference, said outer circumference including an annular groove;
- a joint ball positioned in said housing, said joint ball including a ball pivot extending therefrom;
- a sealing cuff formed of an elastically deformable material, said sealing cuff including an end which is fastened in said annular grove about the outer circumference of said housing and said sealing cuff including another end with an edge profile surrounding said ball pivot, sealingly in a positive locking manner with respect to an axial direction;
- rotational positive-locking means for positively connecting said sealing cuff to said ball pivot, and including an inner non circularly shaped annular surface portion of said sealing cuff edge profile and an outer non circularly shaped peripheral surface portion of said ball pivot which engage each other for preventing relative rotational movement and for preventing relative axial movement, said sealing cuff including rotary elasticity means for compensating for a maximum rotary and swivelling movement of said ball pivot with respect to said housing.

A ball joint for motor vehicles, comprising:
- a housing having an outer circumference, said outer circumference including an annular groove;
- a joint ball positioned in said housing, said joint ball including a ball pivot extending therefrom, said ball pivot having an outer circumferential surface defining a seating surface;
- a sealing cuff formed of an elastically deformable material, said sealing cuff including an end which is fastened in said annular groove about the outer circumference of said housing, and said sealing cuff including another end with an edge profile and having an inner annular surface;
- rotational and axial positive-locking means including a non circularly shaped region formed on said inner annular surface and a non circularly shaped region formed on said seating surface of said ball pivot, said non circularly shaped region formed on said inner annular surface and said non circularly shaped region formed on said seating surface being matched to interengage for preventing relative rotational movement between said sealing cuff and said ball pivot, said seating surface preventing relative axial movement between said sealing cuff and said ball pivot, said sealing cuff being formed of elastic material providing rotary elasticity means for compensating for a maximum rotary and maximum swivelling movement of said ball pivot with respect to said housing.
