Abstract
The utility model discloses an electronic pump's thrust device, including the water pump cover, install dabber in the water pump cover, install at the rotor subassembly of spindle and establish the stator module at water pump shells inner wall, the dabber both ends support on the water pump cover through upper and lower bearing respectively, be equipped with the thrust ring under the upper bearing on terminal surface and the rotor subassembly between the plane, the thrust ring on the plane recess of at least three circumference equipartition has, the recess intussuseption be filled with the coolant liquid. The utility model discloses a set up the recess and at but liquid of recess intussuseption refrigerant filling type, under electronic pump operating condition, utilize the coolant liquid can lubricate upper bearing and thrust ring surface fricative relatively from this betterly at the thrust ring upper surface to reduce friction loss, improve the life of thrust ring.
Description
Technical field
This utility model is related to a kind of thrust brake of electronic water pump.
Background technology
Electronic water pump operates generally under plumbness, due to Fluid pressure effect, the meeting between rotor assembly and bearing
Larger pulling force is produced, to prevent rotor assembly from offseting the magnetic center of stator module, is typically stopped by setting in bearing lower surface
The mode of throw-out collar, improves the stability of rotor assembly operation.In the thrust structure of existing electronic water pump, thrust ring used and bearing
Lower surface joint place is plane contact, during water pump operation, due to without gap, thrust ring one between thrust ring and bearing lower surface
Dry condition is directly in, the thrust ring under pressured state easily weares and teares.
Utility model content
The technical problems to be solved in the utility model is：Overcome the deficiency in prior art, there is provided one kind reduces friction and damages
Lose, improve the thrust brake of the electronic water pump of thrust ring service life.
This utility model solves the technical scheme that its technical problem adopted：A kind of thrust brake of electronic water pump, bag
Include water pump cover, the mandrel in water pump cover, the rotor assembly on mandrel and be located at water pump cover inwall
Stator module, described mandrel two ends respectively by upper and lower bearings on water pump cover, upper bearing (metal) lower surface and rotor
Thrust ring is provided with component between plane, plane has at least three circumferential uniform grooves on described thrust ring, described
Coolant is filled with groove.
Preferably, plane has the uniform groove of three circumferences on described thrust ring, and described groove is from thrust ring week
While extending to thrust ring center.
Further, plane is fixed with spill ring on described rotor assembly, and described thrust ring is fixed in spill ring.
The beneficial effects of the utility model are：This utility model in thrust ring upper surface by opening up groove and in groove
Filling coolant, thus under electronic water pump working condition, upper bearing (metal) can be preferably lubricated with thrust ring phase using coolant
To the surface for rubbing, so as to reduce friction loss, the service life of thrust ring is improved.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is further illustrated with embodiment.
Fig. 1 is structural representation of the present utility model.
The thrust of 1. water pump cover, 2. mandrel, 3. rotor assembly, 4. stator module, 5. upper bearing (metal), 6. lower bearing 7. in figure
The spill ring of 8. groove of ring, 9. coolant 10.
Specific embodiment
This utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with this utility model.
A kind of thrust brake of electronic water pump as shown in Figure 1, including water pump cover 1, the core in water pump cover 1
Axle 2, the rotor assembly 3 on mandrel 2 and the stator module 4 of the inwall of water pump cover 1 is located at, the described two ends of mandrel 2
It is supported on water pump cover 1 by upper and lower bearing 5,6 respectively, wherein on the lower surface of upper bearing (metal) 5 and rotor assembly 3 between plane
Thrust ring 7 is provided with, plane is fixed with spill ring 10 on rotor assembly 3, described thrust ring 7 is fixed in spill ring 10, thrust
The upper plane of ring 7 has the uniform groove 8 of three circumferences, and described groove 8 extends from the periphery of thrust ring 7 to the center of thrust ring 7,
Coolant 9 is filled with described groove 8.
This utility model by opening up groove 8 and the filling coolant 9 in the groove 8 in the upper surface of thrust ring 7, in electronic water
Under pump work state, because the abrasive end face between thrust ring 7 and the lower surface of upper bearing (metal) 5 has the gap of groove 8, and in groove 8
Between be filled with coolant 9 again, thus when friction is produced coolant 9 can well to lubricate upper bearing (metal) 5 relative with thrust ring 7
The surface of friction, so as to reduce friction loss, improves the service life of thrust ring 7.
Above-mentioned embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with this skill
The personage of art will appreciate that content of the present utility model and is carried out, and can not limit protection model of the present utility model with this
Enclose, all equivalence changes made according to this utility model spirit or modification all should be covered in protection model of the present utility model
In enclosing.
