Tensioner for a camshaft-camshaft chain drive

A camshaft-camshaft chain drive for an internal combustion engine, comprising at least two camshaft chain wheels, a drive chain connecting the two camshaft chain wheels and a camshaft bearing bridge for fastening associated camshaft bearings to an engine block component as well as a tensioner, the tensioner comprising:

• a tensioner housing having a guide shoe provided at a guiding side of the tensioner housing,
• a tensioning piston is slidably guided in a piston bore of the tensioner housing, the tensioning piston having a tensioning shoe provided at a tensioning side opposite to the guiding side, and a fastening flange projecting on one side of and laterally from the tensioner housing, the fastening flange having a mounting surface that faces the tensioning side;
• wherein a mounting plane defined by the mounting surface of the fastening flange intersects the tensioner housing at an axial distance from a guiding surface of the guide shoe which corresponds between 0 and 40% of the axial transport length of the tensioner between the guiding surface of the guide shoe and a tensioning surface of the tensioning shoe at a locked transport position of the tensioner;
• and
• wherein the camshaft bearing bridge has a contact surface for receiving the fastening flange, wherein the mounting surface of the fastening flange is in contact with said contact surface for fixing the camshaft bearing bridge to the engine block component.
