A housing for receiving a bearing component is presented, which has a shaft projection, which can be inserted into the recess of the end area of a hollow section and can be pressed together with the end area, wherein the shaft projection is provided with a groove profile, in which the groove profile is prepared by a deformation process or an original shaping process. Notch effect and consequently a weakening of the cross section on the highly stressed shaft projection is avoided by the said processes. The present invention pertains, moreover, to such a groove profile located at a shaft projection of a housing.

Housing for receiving a bearing component and process for manufacturing same

An axle suspension of rigid axles is presented, on the axle body ( ) of which a steering triangle ( ) as well as two longitudinal control arms ( ), which are located at spaced locations from the steering triangle and have different vertical positions, and additionally a stabilizing device ( ) are arranged. The steering triangle has two control arms ( and ), which form an angle with one another and are fastened to a central joint ( ), on the one hand, and are connected to the vehicle body via a guiding joint ( and ) each, on the other hand. The following geometric axes of coordinates are defined on the axle suspension: a first horizontal axis ( ), which extends in the transverse direction of the vehicle and forms the central axis of the axle body ( ) at the same time as well as a second horizontal axis ( ), which extends in the center of the vehicle and in the longitudinal direction of the vehicle and intersects the axis ( ) at right angles and a vertical axis ( ) intersecting the intersection of the horizontal axes ( and ). The central joint ( ) of the steering triangle ( ) is mounted on the axle body with an offset from at least one of the axes ( through ).

A metallic ball pin of a universal joint, preferably one with high load-bearing capacity, for motor vehicles, which is mounted movably in all directions in a bearing shell of a housing with a joint ball 2 designed at one end of a pin stump 1. To improve its functional properties and to reduce its manufacturing costs, a machined joint ball 2 with a through-hole 5 is nonrotatably attached to a fastening pin 4 of a pin stump 1 manufactured by cold forming in the direction of the longitudinal axis of the pin stump 1, and it is held by deforming the fastening pin 4.
