Patent ID: 8162786

Claim:
A traction mechanism drive of an internal combustion engine comprising: an output member having a first belt pulley; at least one drive member having a second belt pulley and being pivotable about a pivot point; a traction mechanism connecting the first belt pulley and the second belt pulley; spring means acting on the drive member, which serves as a tensioning device for pre-tensioning the traction mechanism; a hinge pin; a deflection lever pivotable about the hinge pin between a first end position and a second end position, the first end position being an assembly position and the second end position being an operating position; and said spring means acting on the drive member via the deflection lever, wherein the hinge pin is fixed to the drive member at a position different from the pivot point so that the traction mechanism is pretensioned in the operating position and relaxed in the assembly position.
