Abstract
A drive member (1) for a water pump of the cooling-water circuit of an internal combustion engine, with a drive wheel (7) and a shaft (4) which is coupled to the water pump, is proposed. According to the invention, for the transmission of torque between the drive wheel (7) and the shaft (4), an electromagnetically actuable friction-disk clutch (9, 10, 11, 12) and a second clutch device in the form of an eddy-current clutch (14) are provided, the latter taking up the shaft (4) when the friction-disk clutch is out of engagement. Moreover, a frictional shift clutch for a drive member of this type is proposed.
