摘要： The invention comprises an asymmetric damping tensioner system for belt drives on an engine. A belt is connected between a driver pulley on a crankshaft and any number of driven pulleys. Each driven pulley is connected to an accessory such as an alternator, power steering pump, compressor or the like. The tensioner is placed anywhere before the first component of significant effective inertia, in the belt movement direction. A biasing member in the tensioner is used to maintain a tension in the belt. The tensioner further comprises a damping mechanism to damp belt vibrations caused by the operation of the engine. Tensioner damping friction is unequal or asymmetric, depending upon the direction of movement of the tensioner arm. During acceleration the damping friction of the tensioner in the unloading direction is significantly lower than the damping friction in the opposite, or loading direction, as is the case during deceleration. Lower damping friction during acceleration allows the tensioner arm to quickly adjust to the increase in belt length caused by acceleration. Higher damping friction during deceleration prevents the tensioner arm from being moved too far in the loading direction thereby causing slipping and noise. Asymmetric damping also significantly diminishes overall vibration in the belt during all phases of operation.

摘要： The invention comprises a method of using tensioners to tune a belt drive system. A tensioner having a damping rate is used on an accessory belt slack side and a tensioner having a having a damping rate is used on an accessory belt tight side. Outside of a predetermined engine speed range, the tight side tensioner arm does not move because the dynamic tension in the span is less than the tight side tensioner friction damping. Within a predetermined engine speed range the tight side tensioner arm moves in order to damp a belt drive system vibration.
