US 11,981,058 B2 · One-piece cast component having at least one integrated attachment part, and method for producing a cast component

Abstract

A one-piece cast component having at least one integrated attachment part is disclosed. The component includes at least one pin which is rigidly connected to an attachment part; a housing at least partially enclosing the pin in a contactless manner; the pin being arranged in the axial direction between two axial connecting webs and being rigidly connected via the latter to the housing; the pin being arranged in the radial direction between a plurality of radial connecting webs and being rigidly connected via the latter to the housing; wherein the connecting webs are dimensioned in such a way that only the latter break at respective predetermined breaking points when pivoting the attachment part for the first time relative to the housing, whereafter the attachment part, together with the pin, is mounted so as to be pivotable with respect to the housing. The regions of the connecting webs that remain on the housing after the breaking operation prevent the pin from being removed from the housing. The disclosure further relates to a method for producing such a cast component having an integrated attachment part.

Dependent claims

A one-piece cast component with at least one integrated add-on part, the component comprising:

at least one axle rigidly connected to the add-on part;
an enclosure contactlessly and at least partially surrounding the axle;
wherein the axle is arranged in the axial direction between two axial connecting webs and is rigidly connected to the enclosure via the connecting webs;
wherein the axle is arranged in a radial direction between several radial connecting webs and is rigidly connected to the enclosure via the connecting webs;
wherein the connecting webs are dimensioned in such a way that only these break at respective predetermined breaking points when the add-on part is pivoted relative to the enclosure for the first time and thereafter the add-on part together with the axle is mounted pivotably relative to the enclosure, and
wherein areas of the connecting webs remaining on the enclosure after breaking prevent removal of the axle from the enclosure.

3 more elements

A method for producing a cast component with an integrated add-on part, the method comprising the steps of:

connecting at least one axle to the add-on part;
at least partially surrounding the axle with an enclosure such that the enclosure does not contact the axle;
introducing at least one casting material into a cavity enclosed between two mold halves;
producing a cast component with curing of the at least one casting material,
wherein the axle is arranged in the axial direction between two axial connecting webs and is rigidly connected to the enclosure via the connecting webs;
wherein the axle is arranged in a radial direction between several radial connecting webs and is rigidly connected to the enclosure via the connecting webs;
wherein the connecting webs are dimensioned in such a way that only these break at respective predetermined breaking points when the add-on part is pivoted relative to the enclosure for the first time and thereafter the add-on part together with the axle is mounted pivotably relative to the enclosure,
wherein at least the axle, the enclosure and the connecting webs are produced without undercuts with respect to a predetermined demolding direction;
and
wherein areas of the connecting webs remaining on the enclosure after breaking prevent removal of the axle from the enclosure.
