A tensioner is disclosed that achieves asymmetric damping in part by using a ramp-ramp assembly. The tensioner comprises a tensioner axle defining a pivot axis, an arm mounted on the tensioner axle so as to permit the arm to pivot about the pivot axis, a first tensioner component having first ramp features, a second tensioner component having second ramp features, and a ramp bushing having an upper ramp surface and a lower ramp surface. The first tensioner component is engaged to the arm for rotation therewith and the second tensioner component is coupled to the tensioner axle. The ramp bushing is disposed between the first tensioner component and the second tensioner component such that the upper ramp surface seats within the first ramp features and the lower ramp surface seats within the second ramp features. |
