The utility model is mounted on mechanical water by the preferred arrangement to tradition machinery water pump structure, by electronic water pump module
The inside of pump, and by the clutch action of unilateral bearing, make water pump while there is Mechanical Driven and motor to drive two kinds of Working moulds
Formula.
Compared with prior art, when engine is operated with rated speed, the module of motor assembly does not work the utility model,
Belt pulley drives Pump Shaft rotation by unilateral bearing, ensures the normal operation of engine-cooling system.Work as engine speed
When relatively low or engine is just shut down, full-vehicle control module controls motor operation by circuit board control circuit, by being fixed on yoke
The PM rotor of magnetic axis set outside drives Pump Shaft continuation to be rotated with higher rotation speed, is connect at this time with unilateral bearing outer ring
Pulley speed is relatively low or stops, and the clutch action of unilateral bearing can guarantee that water pump operation does not influence the engine where belt pulley
Train state.Again due to the presence of water storage cavity and drain hole in water pump cover, even if there is coolant liquid leakage at water seal, leakage
Coolant liquid can also be flowed out by drain hole, ensure that the dry environment of motor and circuit board region.
