Abstract
A ball joint with variable friction resistance for a vehicle, the joint having a stud with a joint ball which is held in a housing so as to articulate relative thereto. The housing comprises movable and static housing parts that are movable relative to one another and engage on opposite sides of the ball. A transmission is moved by one housing part so as to exert a variable pressure on the ball. The transmission has axially aligned transmission elements, each of which has a helical ball track. The transmission elements axially rest against one another via balls that are guided between the ball tracks of the transmission elements. A first transmission element can move axially and contact the movable housing part. A second transmission element can rotate about the rotational axis which causes the first transmission element to move axially and exert an axial force on the movable housing part.
