Abstract
A ball-and-socket joint for motor vehicles includes a joint ball (1) provided on a pivot pin (2) mounted movably in a sliding shell (4) made of plastic. A zone of grooves (8) are provided for receiving lubricant on an inner surface of the sliding shell. The sliding shell is inserted into a housing (5) whose inner wall closely surrounds the outer wall of the sliding shell (4). In the zone of the grooves receiving the lubricant, flat recesses (9), which permit radial deformation of the sliding shell (4) in the direction toward the housing, are provided between the housing (5) and the sliding shell (4).
