    Abstract: A pulley unit has a hub configured to be connected to a crankshaft, a pulley coaxial to the hub and supported in a rotationally free manner with respect thereto, a clutch interposed between the hub and the pulley, and an actuator for controlling the clutch. The clutch has an inner disc rotationally coupled to the hub and having an engagement portion housed inside the pulley, a mobile member axially movable between an engagement position in which the mobile member rotationally couples the pulley to the engagement portion of the inner disc and a disengagement position in which the pulley is rotationally free with respect to the inner disc, and an elastic element acting on the mobile member to push it towards the engagement position.

    Abstract: A filtering pulley for an accessory drive of an internal combustion engine, having a hub suitable for connection to an engine accessory, an annular crown provided with a profile configured to cooperate with a drive belt, a coil spring able to transmit torque between the crown and the hub, a first carrier constrained to a first end of the spring and a second carrier constrained to a second end of the spring. The annular crown is externally coaxial to the hub and supported in a rotationally free manner on the hub, and each of the carriers is rotationally coupled to both the hub and the crown with a limited possibility of relative rotation with respect to each of them.

    Abstract translation: 一种用于内燃机附件驱动器的过滤皮带轮，其具有适于连接到发动机附件的毂，设置有配置成与传动带配合的轮廓的环形齿冠，能够在冠部和冠部之间传递扭矩的螺旋弹簧 毂，被限制到弹簧的第一端的第一承载件和限于弹簧的第二端的第二承载件。 环形表冠外部与轮毂同轴并以轮转的方式支撑在轮毂上，并且每个托架以相对于它们中的每一个的相对旋转的有限可能性旋转地联接到轮毂和冠部。
