Driving member for water pump of cooling water circuit of internal combustion engine, has drive wheel, shaft and friction clutch to transmit torque between drive wheel and shaft and torque is switched to output wheel with friction clutch

摘要

The driving member has a drive wheel (1), a shaft (12) which is coupled with the water pump and an electromagnetically operated friction clutch to transmit torque between drive wheel and shaft. The transmitting torque is switched to the output wheel (10) with the friction clutch. The drive wheel and output wheel are supported on the shaft.
