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.

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, characterized in that, 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 (9, 10, 11, 12) is out of engagement, and wherein the drive wheel is designed as a V-belt pulley (7), the friction-disk clutch (9, 10, 11, 12) and the eddy-current clutch (14) lying axially in the region of the width (b) of the V-belt pulley (7).
Frictional shift clutch for an internal combustion engine for the transmission of torque between a drive wheel (7) and a rotating part (3, 21) to be driven, with a friction-disk clutch and with a second clutch device in the form of an eddy-current clutch (14) which takes up the part (3, 21) to be driven when the friction-disk clutch is out of engagement, characterized in that the friction-disk clutch and the eddy-current clutch (14) are positioned concentrically to the axis of rotation of the drive wheel (7), and in that the drive wheel is designed as a V-belt pulley (7), the friction-disk clutch and the eddy-current clutch (14) lying axially in the region of the width (b) of a drive ring (17) of the V-belt pulley (7).
