Abstract
A method for producing a ball joint (18) and/or a chassis component (19), in which a joint ball (1) is made, in which the joint ball (1) is placed in an injection-molding die, in which the joint ball (1) is partially overmolded with a plastic material, and in which the plastic material is hardened to form an injection-molded joint housing (2) for the joint ball (1). A joint housing (2) is formed using the joint ball without a joint pin (10), and the joint ball (1) has respective pole surfaces (3, 4) on two sides remote from one another.
Claims11
A method for producing at least one of a ball joint and a chassis component, in which a joint ball is located, the method comprising:
- placing the joint ball in an injection-molding die,
- partially overmolding the joint ball with a plastic material,
- hardening the plastic material to form an injection-molded joint housing for the joint ball, and, during formation of the joint housing, the joint ball is overmolded without a joint pin, and the joint ball has respective first and second pole surfaces on two sides remote from one another.
A method of producing at least one of a ball joint and a chassis component, in which a joint ball is located, the method comprising:
- placing the joint ball in an injection-molding die,
- partially overmolding the joint ball with a plastic material,
- hardening the plastic material to form an injection-molded joint housing for the joint ball, and
- during formation of the joint housing, the joint ball is overmolded without any joint pin being present and first and second pole surfaces, on opposed sides of the joint ball, rest against the injection-molding die, during the overmolding, so as to avoid interfering with required mobility of the joint ball following manufacture of the ball joint.
