The invention discloses an automobile water pump driven by a direct current brushless motor. The automobile water pump comprises a machine shell, a pump head, the direct current brushless motor and acontrol module used for controlling the direct current brushless motor. A front cover of the pump head is installed at the front end of the machine shell, an impeller of the pump head is installed ona rotor shaft of the direct current brushless motor, the control module is installed on the rear end face of the machine shell, a machine shell rear end cover is installed on the rear end face of themachine shell, a stator of the direct current brushless motor is installed inside the machine shell, a sleeve is installed in an inner hole of the stator, a sleeve center shaft is arranged inside thesleeve, the sleeve is connected with the front end of the machine shell through the front cover of the pump head to be pressed inside the machine shell, the stator passes through the end face of the sleeve in the axial direction to be matched with a spring so as to be pressed inside the machine shell, the front end and the rear end of an inner hole in the rotor shaft are in rotary sleeving connection with the sleeve center shaft through bearings correspondingly, and the axial direction of the rotor shaft is positioned through a clamping spring at the front end of the sleeve center shaft. The automobile water pump is driven by the direct current brushless motor, and compared with a mechanical water pump, operation is smoother, noise is reduced, and the efficiency is higher.
