1. A tensioning device for compensating elongations of a traction element of a traction element drive for an internal combustion engine, comprising:
- an elongated tensioning device for tensioning a traction element, one side of the tensioning device having a surface for contacting the traction element and the other side of the tensioning device having a support surface which is produced from a material with a high strength,wherein the support surface is an inset and formed integrally with the tensioning device, the material of the support surface being injected during production of the tensioning device such that the material of the support surface is permanently coupled with the tensioning device; and
a tensioning element contacting the support surface and loading the tensioning device against the traction element, the tensioning element arranged between the support surface on the tensioning device and a support on the internal combustion engine, wherein the material of the support surface has a higher strength than a material of a remainder of the tensioning device.

Abstract
A tensioning device for compensating for elongations of the traction mechanism, in particular a chain or a timing belt, of a power transmission drive, in particular on an internal combustion engine, having a tensioning mechanism, in particular a tensioning rail, a sliding shoe or tensioning arm having a tensioning roller. A tensioning element is disposed between a support surface on the tensioning mechanism and a support, in particular on the internal combustion engine, and the support surface on the tensioning mechanism is made of a material which has a high strength.
