WATER PUMP FOR THE VEHICLE

摘要

PURPOSE: A water pump for vehicles is provided to improve the waterproofing performance of the water pump because an integrated pump body is formed by insert-molding a connector and a stator. CONSTITUTION: A water pump for vehicles comprises a pump body(110), rotation assemblies(160), and a drive cover(130). A stator(140) and a connector(171) are formed into one body. A rotor chamber and a part of a drive chamber are formed in an upper part and a lower part of the pump body respectively. The rotation assemblies are connected to the rotor chamber. The rotation assemblies comprise a rotary shaft(161) and an impeller(162). The rotor is fixed to the rotary shaft and faces the stator. The impeller is coupled to the upper part of the rotary shaft and rotated by rotations of the rotary shaft. While cooling water flowing from outside is discharged with being compressed. The driver cover covers up the driver chamber connected to a driver(170).
