Abstract
The utility model discloses a kind of wear-resisting type vacuum automobile impeller of pump, including wheel hub, there is an axis hole and multiple blade grooves on the wheel hub, blade, each inclined structure annular array of blade groove are provided with each blade groove, cell body is provided with the two side of the blade groove, four sides of cell body extend close to the edge of blade groove, and the blade coordinates with blade groove gap, and the both ends of blade are set in arc structure, the blade is graphite vanes, and the inner side of the cell body is in empty structure.Both sides are provided with cell body in the blade groove of the utility model impeller, so that most area of blade both sides avoids rubbing and caused abrasion, effectively increase the service life of blade, while alleviate the weight of wheel hub, are easy to motor to drive, reduce power consumption.
Description
Technical field
A kind of impeller is the utility model is related to, more particularly, to a kind of wear-resisting type vacuum automobile impeller of pump.
Background technology
Automobile vacuum pump is typically all braking automobile power-assisted, simultaneously constantly takes out air (close to vacuum, it is impossible to definitely
Vacuum), one side keeps an atmospheric pressure in addition, thus forms negative pressure, can produce and inhale past power, produces push through in other words
Power, thus reach the purpose of power-assisted.
Automobile vacuum pump is mainly made up of parts such as motor, housing, impeller assembly and impeller fixed mechanisms, and prior art is used
Impeller assembly in during use, blade constantly rubs back and forth on wheel hub, and due to rubbing, big, frequency is high, very
Easily there is the problem of leaf destruction, so as to have impact on the overall performance of vavuum pump, therefore be badly in need of one kind can solve it is above-mentioned
The technical scheme of problem.
Utility model content
To solve the above problems, the utility model proposes one kind can effectively reduce blade wear, service life length, use
The good wear-resisting type vacuum automobile impeller of pump of effect.
Technical scheme is used by the utility model：A kind of wear-resisting type vacuum automobile impeller of pump, including wheel hub, the wheel
There is an axis hole and multiple blade grooves on hub, be provided with blade in each blade groove, each inclined structure annular array of blade groove,
It is characterized in that：Cell body is provided with the two side of the blade groove, four sides of cell body extend close to the edge of blade groove, institute
State blade with blade groove gap to coordinate, the both ends of blade are set in arc structure, and the blade is graphite vanes.
Further, the inner side of the cell body is in empty structure.
Compared with prior art, it has the advantages that the utility model：
Both sides are provided with cell body, and the inner side of cell body in the blade groove of wear-resisting type vacuum automobile impeller of pump of the present utility model
In structure is emptied, so that most area of blade both sides avoids rubbing and caused abrasion, blade is effectively increased
Service life, while can also mitigate the weight of wheel hub, motor driving is easily facilitated, power consumption is reduced and improves, improve vacuum pump impeller
Performance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1- wheel hubs；2- axis holes；3- blade grooves；4- blades；5- cell bodies.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Mode, the utility model is further elaborated, it should be appreciated that embodiment described herein is only used
To explain the utility model, it is not used to limit the utility model.
A kind of wear-resisting type vacuum automobile impeller of pump as shown in Figure 1, including wheel hub 1, there is an axis hole 2 on the wheel hub 1
With multiple blade grooves 3, blade 4, each inclined structure annular array of blade groove 3, the blade groove are provided with each blade groove 3
Cell body 5 is provided with 3 two side, four sides of cell body 5 extend close to the edge of blade groove 3, the blade 4 and blade groove 3
Gap coordinates, and the both ends of blade 4 are set in arc structure, and the blade 4 is graphite vanes, and the inner side of the cell body 5 is in
Empty structure.
Both sides are provided with cell body, and the inner side of cell body in the blade groove of wear-resisting type vacuum automobile impeller of pump of the present utility model
In structure is emptied, so that most area of blade both sides avoids rubbing and caused abrasion, blade is effectively increased
Service life, while can also mitigate the weight of wheel hub, motor driving is easily facilitated, power consumption is reduced and improves, improve making for vacuum sheet
With performance, by the way that blade is set into graphite vanes, so as to ensure the intensity of blade well.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New spirit and scope are defined.On the premise of the utility model design conception is not departed from, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, the scope of protection of the utility model, this reality all should be dropped into
With new claimed technology contents, all record in detail in the claims.
