What is proposed is a pulley decoupler (1) for the transfer of drive torque from the belt of an auxiliary unit belt drive to the shaft of one of the auxiliary units; having: – a pulley (2) – a hub (4) to be attached to the shaft – and a series connection arranged between the pulley and the hub in the flow of drive torque and consisting of a one-way clutch (10) and a helical torsion spring (11), which extends in the direction of the axis of rotation (12) of the pulley decoupler and widens radially under transfer of the drive torque, wherein the ends of the helical spring make contact with a spring support surface (30, 39), rising in an axially ramp-shaped manner, of a first spring plate (18) and of a second spring plate (24). In that context, one of the spring plates should be a shaped sheet metal part with the spring support surface formed thereon. |
