ABSTRACT:
A joint unit such as for mounting the vehicle control arm of a motor vehicle, is provided with a control arm-side housing (1), in which a pivot pin (2) is mounted pivotably by means of a spheroidal bearing surface (3), wherein the joint unit has a securing unit against the separation of the housing (1) from the pivot pin (2). The securing unit includes a securing bolt (9), arranged within the pivot pin (2) essentially in parallel to the central longitudinal axis of the pivot pin (2) and with a blocking element (12) at a free end. A securing mount (13) is located within the housing (1) or the pivot pin (2) and in this the blocking element (12) is mounted in a contactless manner in the mounted state of the joint unit. The securing mount (13) is part of the securing unit, and the securing bolt (9) is fixed to the component of the joint unit (housing (1) or pivot pin (2)) that is not provided with the securing mount (13). Redundant securing of a joint unit against separation of the housing (1) from the pivot pin (2), which is not visible from the outside and is thus advantageous from both a safety engineering viewpoint and a visual viewpoint is achieved.
