A suspension arm () for a vehicle including a bearing () and a journal (). The bearing () has at least one elastic sub-element () and the bearing () is arranged on the journal () of the suspension arm () and encloses the journal (). The journal () and the bearing () are designed to co-operate with one another in such manner that the bearing (), relative to the journal (), has a transition fit. The bearing () is fixed on the journal () of the suspension arm () by a fastening element ().

Rubber bearing connection

A holder () for a spring () which has a spring fastening area () for fastening the spring () to the holder () and a wheel carrier fastening area () for fastening a wheel carrier () to the spring. The holder () further has a deformable zone () for transmitting force from the spring fastening area () to the wheel carrier fastening area ().

Holder for a spring

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.
