Patent ID: 7390276

Claim:
A belt assembly for use in driving camshafts of an internal combustion engine, comprising: a driving gear; at least one driven gear; a belt coupling the driving gear with the at least one driven gear; a first and a second tensioner blade; a two-part hinge mechanism for coupling together the first and the second tensioner blades so as to transmit at least one of a defined force and a motion, wherein the two parts of the two-part hinge mechanism are coupled together via a hinge point; a first tensioning device, supported on one of the tensioner blades on one side and externally on another side, the first tensioning device subjecting the one tensioner blade to a tension force action; a second tensioning device which subjects the hinge point to a tension force action, the second tensioning device being supported at the hinge point on one side and, at least indirectly, on the internal combustion engine on the other side.
