Abstract

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.
