Abstract
A method of producing a movable tensioning element of a tensioning device for tensioning flexible drive means, in particular for timing chain drives of internal combustion engines, the tensioning element having at least a tensioning piston and a tensioning rail made of a plastic material, with the tensioning rail being arranged on a tensioning end of the tensioning piston. A correspondingly implemented tensioning element as well as a tensioning device including such a tensioning element is provided. The method of producing the movable tensioning element includes placing the tensioning piston into an injection mold suitable for producing the tensioning rail; injecting the plastic material into the injection mold; encompassing the tensioning piston by the plastic material in certain areas thereof; and letting the plastic material solidify under formation of a positive connection between the tensioning piston and the tensioning rail.
