ABSTRACT:
In a tensioner lever assembly for a chain transmission, an auxiliary lever, arranged to pivot relative to a main tensioner lever, engages a free span of the chain approaching the main lever from a driving sprocket. The auxiliary lever can be pivoted coaxially with the main lever, and can extend either toward the center of the main lever, or toward the driving sprocket. Alternatively, the auxiliary lever can be pivoted on the main lever at a location remote from the pivot axis of the main lever, and engaged with a free span of the chain moving away from the main tensioner lever and approaching a driven sprocket.
