摘要： The invention relates to a ball-and-socket joint, preferably for a motor vehicle, wherein the ball (1) located on a pivot pin is movably received by a socket (3) that consists of a synthetic material. The socket is provided with lubricant-guiding recesses (5) on its inner surface that faces the ball and is received by a housing. According to the invention, the recesses may be grooves (5) in the shape of a structural unit with groove sections that extend at an angle to the center longitudinal axis of the ball-and-socket joint or they may be configured as microscopically small indentations. This new structural design results in a pump effect when the ball is moved across the groove sections. Said pump effect draws the lubricant that is present in the groove sections into the gap between the ball and the socket, thereby guaranteeing a lubrication of the ball-and-socket joint under all operating conditions that is superior over the state of the art.
摘要翻译： 优选用于机动车辆的球窝接头技术领域本发明涉及一种优选用于机动车辆的球窝接头，其中，位于枢轴销上的球（1）被由合成材料构成的插座（3）可移动地接收。 插座在其面向球的内表面上设置有润滑剂引导凹槽（5），并由壳体接收。 根据本发明，凹槽可以是具有凹槽部分的结构单元形状的凹槽（5），凹槽部分相对于球窝接头的中心纵向轴线以一定角度延伸，或者它们可以被构造为微小的凹槽 。 这种新的结构设计在球穿过凹槽部分时产生泵效应。 所述泵效应将凹槽部分中存在的润滑剂吸入球和承窝之间的间隙中，由此在所有优于现有技术的操作条件下保证球窝接头的润滑。

摘要： The invention relates to a lubricant for a ball-and-socket joint. Ball-shaped particles having two different particle sizes are inserted into an oil or a lubricating grease. The greater particles act as spacers which prevent a ball of the ball-and-socket joint to get placed onto a step bearing when the ball-and-socket joint is at a standstill. The smaller particles prevent an agglomeration of the greater particles. The smaller particles keep the greater particles at a distance from each other and thus distribute said greater particles in the ball-and-socket joint.
