Fastening assembly of a camshaft adjuster

摘要

A fastening assembly for fastening a camshaft adjuster to a camshaft, having an input part that can be brought into driving engagement with a crankshaft, an output part that is non-rotationally connected to the camshaft, the output part being mounted rotationally adjustably with respect to the input part, and a control mechanism, by which a rotational angle position between the input and output parts can be adjusted. The output part is provided with a central axial opening penetrated by an end section of the camshaft. The end section has a thread-bearing thread section, which is screwed together with a tension nut acting on the output part such that the output part and the camshaft are axially loaded for the non-rotational connection thereof. To this end, the tension nut is elastically loaded in the axial direction or relieved in the axial direction.

1. A fastening arrangement for fastening a camshaft adjuster to a camshaft, comprising: a drive part that can be brought into drive connection with a crankshaft, a driven part that is locked in rotation with the camshaft and is supported for rotation relative to the drive part, and an adjustment mechanism that is adapted to adjust a rotational angle position between the drive part and driven part, wherein
the driven part is provided with a central, axial opening penetrated by an end section of the camshaft, the end section has a thread-bearing threaded section that is screwed together with a clamping nut to load the driven part so that the driven part and the camshaft are clamped in an axial direction to provide a rotationally locked connection, and the clamping nut is configured to compress elastically in the axial direction or to release tension in the axial direction, so that loosening of the clamping nut is counteracted,wherein the driven part is clamped in the axial direction by the clamping nut with a support surface formed by the camshaft, and the end section of the camshaft is provided with a truncated-cone-shaped conical section that is arranged between the support surface and the threaded section and on which the driven part sits, wherein there is a connection element connecting the clamping nut and the end section of the camshaft to each other in a rotationally fixed manner.
