The purpose of this utility model is to provide a kind of electronic water pump, solves that the manufacturing cost that existing electronic water pump has is high, the problem of poor stability during complex process and wheel rotation.
The electronic water pump that this utility model provides, including:
Stator, rotor, electronic control unit, impeller, water pump cover and the water pump drive end bearing bracket with water inlet and outlet, described stator is positioned at the inside of described water pump cover, described stator interior is formed with the first cavity structure, described internal rotor is formed with the second cavity structure, described impeller is formed or is provided with impeller support shaft；Wherein, described rotor inserts in the first cavity structure of described stator interior, and described impeller support shaft is fixedly mounted in the second cavity structure of described internal rotor.
Further, described electronic water pump also includes impeller gripper shoe, and this impeller gripper shoe is between described impeller and rotor, and described impeller support shaft passes described impeller gripper shoe.
Further, described impeller gripper shoe being formed with bearing mounting hole, described impeller support shaft passes this bearing mounting hole.
Further, described electronic water pump also includes bearing, and this bearing holder (housing, cover) is contained in described impeller support shaft and its outer ring is fitted in the inside of described bearing mounting hole.
Further, described impeller gripper shoe is fixedly mounted on described water pump cover or on described water pump drive end bearing bracket.
Further, described electronic water pump also includes the rear end cap with electric linkage function, and this rear end cap coordinates installation with described water pump cover.
Compared with prior art, above-mentioned electronic water pump has the advantage that 1) volume of rotor is greatly reduced, and then reduces cost；2) owing to supporting rotor and impeller by the way of new, thus the stability rocking, improve product is decreased.
