Abstract: A device for transmitting a torque from an internal combustion engine to a secondary assembly, in particular the compressor of an air conditioning system of a motor vehicle, with a hub for connection to the secondary assembly shaft and with a belt pulley arranged rotatably on the secondary assembly housing, the belt pulley and the hub being connected to one another via one component (14) for vibration damping and via another component (8) for overload protection, the overload protection being designed in such a way that the connection between the belt pulley and hub is broken when a predetermined torque is exceeded, is to be improved in such a way that both the desired vibration damping is ensured and an exactly responding and functionally reliable overload protection is ensured.

Abstract: A drive gear for a motor vehicle including a starter disc having a hub for attachment to a shaft of a vehicle motor for joint rotation therewith, and a drive ring which is supported on the starter disc, is provided with a plurality of holes for connecting the drive ring to a converter of the automatic transmission of the vehicle and has, in the region of the holes, protrusions which engage in corresponding recessed openings formed in the starter disc.
