Patent ID: 8210143

Claim:
A camshaft arrangement for a motor vehicle engine, comprising: two shafts arranged coaxially one inside the other, in which a hollow outer shaft and an inner shaft are arranged so as to be rotatable relative to one another; an outer shaft cam attached to the outer shaft for conjoint rotation therewith; and an inner shaft cam having an inside diameter surface and rotatably supported by the outer shaft and attached to the inner shaft for conjoint rotation therewith by first and second connecting elements, which protrude with play through recesses in the outer shaft to allow limited relative rotation between the inner and outer shafts, wherein: the first connecting element being inserted into a receptacle in the inner shaft in such a way that a protruding part of the connecting element protrudes out of the receptacle, and that the protruding part is inserted at least partially into a cutout formed on the inside diameter surface of the inner shaft cam and without extending to a radial outer surface of the inner shaft cam, said cutout extending axially from one end side of the inner shaft cam and at least partially through the inner shaft cam, and that the protruding part has at least two circumferentially spaced opposite side surfaces which bear with an interference fit against two corresponding inner surfaces of the cutout of the inner shaft cam to radially affix the inner shaft cam to the inner shaft; the second connecting element being designed in the form of a radial member which is disposed in a passage opening extending through the inner shaft cam and also in a second receptacle of the inner shaft and which is held with an interference fit in one of the passage opening and the receptacle to axially affix the inner shaft cam to the inner shaft; and the recesses in the outer shaft have a circumferential width greater than a width of the connecting element, enabling movement of the inner shaft relative to the outer shaft by an adjustment angle.
