Joint unit and method for lubricating a joint unit

The invention relates to a joint unit for a motor vehicle having a housing (1) and in the housing (1) mounted pivot (2) and a between the housing (1) and a bearing section (3) of the pivot pin (2) existing bearing shell (4 ), which (with its outer surface 5) is mounted at least partially in the housing (1) and (on their (the bearing portion 3) of the pivot pin 2) facing inner surface (6) recesses (7) for a lubricant. According to the invention it is proposed that the bearing shell (4) via at least one bearing shell (4) from the inner surface (6) to the outer surface (5) penetrates, a flow passage forming opening (8) has. Moreover, a method for lubricating a joint unit is presented, wherein the elastic deformability having bearing shell (4) during the relative movement of the pivot pin (2) in the housing (1) creates a pumping action that allows for distribution of the lubricant on the lubricant duct system.
