Fig. 1 is the structural representation of the utility model motor car engine with cooling waterpump;
Fig. 2 is a fixedly partial enlarged drawing of impeller shown in Figure 1;
In Fig. 1, Fig. 2,1, permanent magnet DC motor; 2, rear end cover; 3, outer steel; 4, lower flange; 5, interior magnet steel; 6, water outlet; 7, front cover; 8, water intake; 9, impeller; 10, back shaft; 11, Sealing; 12, electric machine main shaft.
Embodiment
As Fig. 1, shown in Figure 2, motor car engine comprises permanent magnet DC motor 1 with cooling waterpump, the rear end cover 2 of permanent magnet DC motor 1 one ends, outer steel 3, flange plate 4, interior magnet steel 5, front cover 7 and impeller 9, have water intake 8 and water outlet 6 on the front cover 7, outer steel 3, flange plate 4, interior magnet steel 5 and impeller 9 are positioned at the cavity of rear end cover 2 and front cover 7 formation, outer steel 3 is positioned at the end of electric machine main shaft 12 and rotates with electric machine main shaft 12, the edge of flange plate 4 is fixed between rear end cover 2 and the front cover 7, the shape at the middle part of flange plate 4 and outer steel and interior magnet steel adapt, the middle part of flange plate 4 is arranged between outer steel 3 and the interior magnet steel 5, impeller 9 forms the cavity of water cycle between flange plate 4 and the front cover 7 between interior magnet steel 5 and front cover 7.All be furnished with Sealing between the edge of flange plate 4 and the rear end cover 2 and between the edge of flange plate 4 and the front cover 7.The center line of the water intake 8 of front cover 7 is positioned on the elongation line of electric machine main shaft 12 center lines, and the center line of water outlet 6 is perpendicular to the center line of water intake 8.
Interior magnet steel 5 is provided with a plurality of positioning steps hole near a side of impeller 9, impeller 9 is provided with the locating column that matches with the positioning step hole of interior magnet steel 5, the material of impeller 9 is engineering plastics, be injected with the back shaft 10 that forms one on the flange plate 4, the center line of back shaft 10 is positioned on the elongation line of electric machine main shaft 12 center lines, interior magnet steel 5 and impeller 9 match with back shaft 10, and magnet steel 5 and impeller 9 rotate with outer steel is concentric in guaranteeing like this, avoid vibrations.Use the impeller of engineering plastics moulding that locating column is arranged, with after the positioning step hole of interior magnet steel cooperates,, realize the nothing breakage, fixed purpose respectively by mode and the interior magnet steel riveted that locating column is added thermal distortion.
Electric machine main shaft rotation when permanent magnet DC motor, relative inside and outside magnet steel carries out the transmission of moment of torsion by being coupled, thereby make the impeller rotation, realize that liquid enters the pump housing from water intake, the negative pressure that is subjected to impeller rotation generation sucks the pump housing with liquid, blade structure by impeller is exerted pressure to liquid, finally flows out from water outlet, realizes water cycle.
