Disclosed is a cooling water pump with a floating impeller for a motor vehicle, comprising a support (6), wherein a stator (5), a water pump cover (2), a socket injection molding (2), a controller (8) and a rear cover (9) are mounted on the support separately by bolts. A rotor impeller injection molding (3) is mounted at the center of the stator (5). The rotor impeller injection molding (3) is of a design integrating a water pump impeller with an electric machine rotor. When the electronic cooling water pump is operating, the interaction between the magnetic field generated by the stator (5) and the magnetic field generated by the permanent magnets in the rotor impeller injection molding (3) can not only turn the rotor impeller injection molding (3) at a certain rotation speed, but also make the rotor impeller injection molding float automatically in the center of the stator. As it rotates, the impeller remains at all times in a magnetic floating state, so it will not experience friction with other components, and the mechanical loss in the motor vehicle cooling water pump is reduced and the efficiency of the motor vehicle cooling water pump is increased, thereby reducing the fuel consumption of the motor vehicle.
Description
technical field [0001] The invention relates to an automobile generator cooling device, in particular to an automobile cooling water pump. Background technique [0002] With the development of society and the advancement of science and technology, cars have gradually entered thousands of households, and people have put forward higher requirements for driving comfort. Therefore, as a leader in automotive cooling systems, it is obligatory to continuously innovate cooling system technology to meet the ever-increasing demands of consumers. [0003] Nowadays, abnormal noise of automobiles has become an important factor affecting driving comfort. Among them, the abnormal noise from the automobile cooling water pump accounts for a large proportion of the abnormal noise of the automobile, and the abnormal noise of the automobile cooling water pump is also one of the most important failure modes of the automobile cooling water pump. The abnormal noise produced by the bearing in the...
