Automatic traction mechanism tensioner for tensioning belt of traction mechanism drive in vehicle, has slide bearing bush and friction element formed as single-part as combination element

摘要

The tensioner (1) has a housing part (2) and a tensioning part (5) rotatable relative to each other around a common rotational axis (4) with respect to the housing part by spring force of a spring (6) that is arranged in the housing part. A friction element (12) is arranged between the spring and the housing part, where the spring is positioned concentrically to the rotational axis. A slide bearing bush (11) and the friction element are formed as a single-part as a combination element (10). The friction element is provided in effective contact with the housing part.
