TRANSMISSION PULLEY FOR AUTOMOTIVE ACCESSORY, MANUFACTURING METHOD AND METHOD FOR DISASSEMBLING SUCH PULLEY

摘要

The present invention relates to a pulley (1) transmission for automotive accessory, in particular for an air conditioning compressor. This pulley (1) comprises a hub centered on a central axis (X1) and adapted to be secured to a shaft belonging to the automobile accessory, a ring comprising a radial rim (22) and an outer peripheral track (24) of rotational drive of the crown by a belt, an elastically deformable member (30) and an annular insert (40). The pulley (1) is characterized in that the elastically deformable member (30) is positioned between the annular insert (40) and an outer surface (14) of the hub, and in that it also comprises means (60). ) of coupling of the annular insert (40) with the ring gear, adjustable between a coupled configuration where the annular insert is secured to the ring gear around the central axis (X1) and a disengaged configuration where the insert ring is separable from the crown. The invention also relates to a method of manufacture and a method of dismounting such a pulley (1).
