A ball-joint for motor vehicles, having a bearing shell made of an elastic plastic inserted between a joint housing (4) and a ball head (2) of a ball pin (1) with rotational and tilting movement, which bearing shell is supported by ribs (13, 17) on its outside in the joint housing (4), lubrication pockets being formed in the regions located between the ribs (13, 17) under the influence of a joint prestress or load on the inside of the bearing shell (3), is to have an improved joint lubrication in order to allow even tilting and rotational moments and to simplify the manufacture. For this purpose, it is proposed that the ribs (13) of the bearing shell (3) are arranged extending obliquely and spirally in relation to the joint axis (axis of the untilted ball pin). <IMAGE> |
