Description
Technical field
The utility model is related to a kind of water pump structure, especially a kind of electronic water pump for automobile.
Background technology
With more and more higher of the country to environmental requirement, electric automobile is just developed with speed with rapid changepl. never-ending changes and improvements.Electric automobile
Battery, motor, electric machine controller, the parts such as charger can all produce substantial amounts of heat, heat one during work
Direct product will be poly- to cause related components to fail, or even spontaneous combustion, therefore electric car must design cooling system and related components are entered
Row cooling.But, because electric automobile eliminates traditional explosive motor, so also cannot provide cold by mechanical water pump
But, electronic water pump for automobile is just arisen at the historic moment in this context.Such as the Chinese invention patent of Patent No. 201310160734.1
A kind of electronic water pump for automobile is disclosed, it includes pump case, pump head, shell, rotor and stator；The pump head is installed on one end of pump case
Composition pump chamber is enclosed on face and in pump case, shaft core is fixed with the pump chamber, the inner of the shaft core is fixedly connected with pump case, on the pump head
Water inlet and delivery port are provided with, the water inlet connects pump chamber with delivery port；The shell is installed on the other end of pump case
And enclose the sealed accommodating cavity of composition with pump case；The rotor is located in foregoing pump chamber, before one end of the rotor is rotatably installed on
State in shaft core, the other end of the rotor is provided with impeller, the impeller has water inlet side and water outlet side, water inlet side is just right
In foregoing water inlet, water outlet side is right against foregoing delivery port；The stator is fixed in foregoing accommodating cavity and surrounded foregoing
Rotor；And, static sealing circle is folded between the pump head and pump case and form static sealing structure and by the water channel in pump chamber
It is completely isolated in stator.However, in above-mentioned electronic water pump for automobile, can produce abrasion with shaft core when rotor is rotated, cause electronic water
Pump service life is not long, and noise is bigger than normal.
The content of the invention
Noise less electronic water pump for automobile when technical problem to be solved in the utility model is to provide a kind of operation.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of electronic water pump for automobile, including pump
Be provided with mutually isolated first chamber and second chamber in shell, described pump case, in described first chamber within outer according to
Secondary be provided with stator, rotor and shaft core, described second chamber is fixedly installed the controller electrically connected with described stator,
Described rotor is rotatably arranged in described shaft core, and one end of described rotor is fixedly installed impeller, and described turns
It is provided with the first self-lubricating plain bearing between one end of son and described shaft core, the other end and described axle of described rotor
The second self-lubricating plain bearing, described the first self-lubricating plain bearing and the second described self-lubricating sliding are provided between core
Cooling chamber is formed between bearing.
Metal division board is provided between described first chamber and described second chamber, described controller, which is fixed, to be set
Put on described metal division board, insulating radiation glue is provided between described controller and described metal division board.Dissipate
Thermal effect preferably, is capable of the maximum operating temperature of lifting controller, so as to increase electric automobile performance.
Compared with prior art, the utility model has the advantage of by setting first between one end of rotor and shaft core
Self-lubricating plain bearing, sets the second self-lubricating plain bearing between the other end and shaft core of rotor, effectively reduces rotor
The noise produced during rotation, substantially reduces the abrasion brought when rotor is rotated to shaft core；Into the coolant of impeller from first certainly
Enter in gap between lubrication sliding bearing and shaft core in cooling chamber, preferable cooling effect is played to internal rotor, is entered
One step increases the service life of electronic water pump for automobile.
