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.This is achieved in that the component for overload protection is formed by a driver disk (8) which is positively held fixedly in terms of rotation on the hub (2) in such a way that the transmission of force between the hub (2) and the driver disk (8) is terminated directly and permanently when a specific predetermined torque is exceeded.
