| 摘要 | A generator arrangement for an auxiliary-assembly belt drive of an internal combustion engine, having a starter generator (1) with a belt pulley (6) and a belt tensioner (2) which includes the following:—a first tensioning lever (8) with a first tensioning roller (4),—a second tensioning lever (9) with a second tensioning roller, these tensioning rollers being arranged in front of and behind the belt pulley in a circulating direction of the belt (3) and applying a pretensioning force onto the belt,—a spring means (7) which is arranged between the tensioning levers and which moves the tensioning rollers towards each other, thereby generating the pretensioning force,—and a locking arrangement (11), by which the tensioning levers can be locked relative to each other in a position in which the tensioning rollers are moved away from each other, thereby reducing or canceling the pretensioning force. The generator arrangement also includes another locking means (15) by which one of the tensioning levers can be locked relative to the starter generator. | ||

| 主权项 | 1. A generator arrangement for an auxiliary unit belt drive of an internal combustion engine with a starter generator having a belt pulley and a belt tensioner, the generator arrangement comprises: a first tensioning lever with a first tensioning roller, a second tensioning lever with a second tensioning roller, wherein the tensioning rollers are arranged in front of and behind the belt pulley in a circulating direction of the belt and apply a pretensioning force onto the belt, a spring element that is tensioned between the tensioning levers and moves the tensioning rollers toward each other while generating the pretensioning force, and a locking element by which the tensioning levers are locked relative to each other in a position in which the tensioning rollers are moved away from each other while reducing or cancelling out the pretensioning force, and an additional locking element by which one of the tensioning levers is locked relative to the starter generator. | ||
