Abstract
An automotive tension device features a pair of pulleys which are pivotally mounted on the same pivot arm. The pulleys are positioned within the drive system (e.g., a belt drive system) in such a manner that the moments relative to the pivot axis created by the force resultant of the driving member passing around each of the pulleys are oppositely directed. Thus, the pulleys provide rotational support for each other. The tension device and arrangement is positioned within a belt drive system having a combination starter/generator, wherein the crankshaft ordinarily drives the belt but the starter/generator drives the belt on engine startup (an arrangement which creates varying kinematic conditions within the belt). One of the pulleys bears against a first, crankshaft-driving portion of the driving member extending from the crankshaft pulley to the starter/generator pulley on the driving side of the crankshaft, and the other pulley bears against a second, starter/generator driving portion of the driving member extending from the starter/generator pulley to the crankshaft pulley on the driving side of the starter/generator pulley.
