Abstract

An arrangement for coupling two components that can move relative to each other in a switchable valve train component for an internal combustion engine is provided, with a coupling element ( 3 ) that can be moved for coupling the components with a flattened coupling surface ( 5 ) for contacting a corresponding locking contour. The locking contour has recesses ( 7 ) in which the coupling element ( 3 ) can engage so that it can move in contact with the locking contour for coupling with its coupling surface ( 5 ) in a position slightly rotated relative to a predetermined coupling position.

First claim

The invention claimed is:

1. An arrangement for coupling two components that move relative to each other in a switchable valve train component for an internal combustion engine, the arrangement comprising a coupling element that is movable for coupling the two components, the coupling element including a flattened coupling surface for contact on a corresponding locking contour, and the locking contour has recesses in which the coupling element is engagable so that the coupling element is movable into contact with the locking contour for coupling with the coupling surface in a position that is rotated relative to a predetermined coupling position, and the recesses form slots that run in a displacement direction of the coupling element which the coupling element overlaps when the coupling element is in contact with the locking contour.

2. The arrangement according to claim 1 , wherein the recesses form rounded sections on which the coupling element is automatically oriented for coupling in the rotated position with the coupling surface in the predetermined coupling position.

3. The arrangement according to claim 2 , wherein the recesses on the locking contour define a locking surface for contacting the coupling surface and the rounded sections are formed in a transition to the locking surface.

4. The arrangement according to claim 1 , wherein the flattened coupling surface of the coupling element is planar, the corresponding locking contour has a corresponding locking surface that is coplanar with said coupling surface, and the coupling surface is placed in a parallel coupling position flat on the locking surface.

5. The arrangement according to claim 1 , wherein the locking contour is constructed by master forming or shaping.

6. A switchable rocker arm for a valve train of an internal combustion engine, the switchable rocker arm comprising: an inner lever and an outer lever that are pivotable relative to each other, and a coupling arrangement for coupling the inner lever and the outer lever together, the coupling arrangement comprising a coupling element that is movable for coupling the inner lever to the outer lever, the coupling element including a flattened coupling surface for contact on a corresponding locking contour, and the locking contour has recesses in which the coupling element is engagable so that the coupling element is movable into contact with the locking contour for coupling with the coupling surface in a position that is rotated relative to a predetermined coupling position, and the recesses form slots that run in a displacement direction of the coupling element which the coupling element overlaps when the coupling element is in contact with the locking contour.

7. The switchable rocker arm according to claim 6 , wherein the coupling element is arranged to be movable on the outer lever and is arranged for coupling on the locking contour formed on the inner lever.

8. The switchable rocker arm according to claim 7 , wherein at least one of the outer or the inner levers are made at least partially from sheet metal.
