Abstract
A belt tensioner controls the pretension of a belt for an ancillary component such as a starter/generator. The ancillary component may apply torque in each direction at different times. The starter/generator has a generator shaft and a generator belt pulley around which the belt passes. A flange is fixed to the starter/generator with a bearing sleeve which surrounds the generator shaft. A first tensioning arm and a second tensioning arm are each formed as circular rings and mounted on the bearing sleeve so as to pivot against each other. One tensioning arm is supported on an inner side of the bearing sleeve while the other tensioning arm is supported on the outer side of the bearing sleeve. Two tensioning rollers are mounted on the tensioning arms and apply a pretensioning force to the belt before and after the generator belt pulley in the belt running direction.
