Device i.e. camshaft adjuster, for changing relative angle position of camshaft opposite to crankshaft of internal combustion engine, has fastening ring that exhibits flattened form in edge area adjacent to partial radially extending gap

摘要

#CMT# #/CMT# The device has a drive element driven by a crankshaft and rotatably supported opposite to a camshaft. A torsion spring (1) is effectively arranged between the camshaft and the drive element. Ends (2) of the torsion spring are undisplaceably arranged with the camshaft and the drive element or a stator (4) of a camshaft adjuster in a peripheral direction (U). A fastening ring (5) is arranged at the drive element in a torque-proof manner. The ring exhibits a partial radially extending gap (6) at a peripheral area. The ring exhibits a flattened form in an edge area adjacent to the gap. #CMT#USE : #/CMT# Device i.e. camshaft adjuster, for changing a relative angle position of a camshaft opposite to a crankshaft of an internal combustion engine #CMT#ADVANTAGE : #/CMT# The ends of the torsion spring are undisplaceably arranged with the camshaft and the drive element in the peripheral direction, thus avoiding collision and/or entrenching of the ends of the spring, and hence ensuring collision-free assembly and collision-free operation of the device with respect to a return spring. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective sectional view of a fastening ring of a camshaft adjusting system before which a torsion spring is arranged.
