Abstract:
Chain drive of a V-engine having overhead camshafts which are driven by a crankshaft and each of the camshafts by a separate chain, in which tensioner blades swivellably assigned to a respective slack run of the separate chain are acted upon by hydraulic chain tensioners, the hydraulic chain tensioners are of the same construction,wherein the tensioner blades have in free end areas contact ramps for spherically shaped end sections on tensioning pistons of the chain tensioners, said contact ramps being arranged in a sloped manner such that the first chain tensioner is arranged in an area of an inlet-side longitudinal side of a first cylinder head, and the second chain tensioner is arranged in an area of an outlet-side longitudinal side of a second cylinder head, wherein the chain tensioners are arranged substantially transverse to one another with the first chain tensioner vertically aligned to vertically sloped and the second chain tensioner horizontally aligned to horizontally sloped, wherein each said chain tensioner is equipped with leakage devices in both end areas of the tensioning pistons, said leakage devices being operable for accommodating different venting directions.
