ABSTRACT:
The invention is an improved belt tensioner for a belt drive system having a belt tensioner, a first belt tensioner pulley, a crankshaft pulley, an accessory pulley, and a power transmission belt trained about the first belt tensioner, crankshaft, and accessory pulleys. The belt tensioner is of the type that includes an attachment point adapted to be affixed to a stationary point relative to a cylinder block of an engine, a track, and a first carrier mounted in sliding relation with the track with two degrees freedom of movement. The first belt tensioner pulley is rotatably mounted upon the first carrier for engaging the power transmission belt. A resilient member biases the first carrier in longitudinal relation to the track. The improvement comprises the tensioner including a second carrier mounted in sliding relation with the track with two degrees freedom of movement. A second belt tensioner pulley is rotatably mounted upon the second carrier for engaging the power transmission belt. The second carrier is biased in longitudinal relation to the track.
