Abstract
An articulated unit for a motor vehicle with a housing () and a link pin () supported in the housing (), and a bearing shell () disposed between the housing () and a bearing section () of the link pin (), with the bearing shell () supported with its outer surface () at least in sections in the housing () and having on its inner surface () facing the bearing section () of the link pin () recesses () for a lubricant. The bearing shell () has at least one opening () which extends through the bearing shell () from the inner surface () to the outer surface () and forms a flow channel. A method for lubricating an articulated unit is presented, wherein the bearing shell () having elastic compliance produces during the relative movement of the link pin () in the housing () a pumping action, which enables distribution of the lubricant via the lubricant channel system.
