The invention relates to a tensioning device pertaining to a traction mechanism drive, said tensioning device comprising a tensioning piston which is mounted in an axially mobile manner and provided with a fixing shaft facing the traction mechanism. Said tensioning device also comprises a tensioning shoe consisting of a polymer plastic and mounted on the fixing shaft by means of a bearing borehole, and a disk-shaped metallic supporting element which is fixed to the fixing shaft by means of a bearing borehole. The aim of the invention is to improve the force transmission between the tensioning shoe (2) and the tensioning piston (5). To this end, the supporting element (11) is pre-mounted in or on the tensioning shoe (2) in a positively and/or non-positively fixed manner, and the supporting element (11) is connected to the tensioning piston (5), in the mounted state, by means of a press fit between the bearing borehole (12) and the fixing shaft (4), and is applied to a section (9) of the tensioning piston (5). |
