Description
Technical field
This utility model relates to motor in electric automobile and wheel system, particularly relates to a kind of wheel hub motor rotor and vehicle wheel
Hub integrated device.
Background technology
Wheel hub motor is the development trend of drive system of electric automobile, but wheel hub motor is simplifying the same of conventional ADS driving structure
Time, add the unsprung mass of suspension system, car load handling is brought adverse effect, it is therefore necessary to reduce wheel hub electricity
The quality of machine drive system.At present in the design of In-wheel motor driving system, drop by the way of reducing each component weight
Low unsprung mass, though obtaining certain effect, but the structural manufacturing process that result also in each parts is complicated, the fraud that cost is significantly increased
End.
Therefore, it is necessary to consider from the system integration, design a kind of simple in construction, low cost, device that weight loss effect is good,
To solve the problems referred to above.
Utility model content
It is big that the purpose of this utility model is to solve In-wheel motor driving mass of system, undesirable problem of dispelling the heat, it is provided that
A kind of simple in construction, low cost, the lightweight integral type rotor hub of good heat dissipation effect.
This utility model is achieved in that
This utility model provides a kind of wheel hub motor rotor and hub for vehicle wheel integrated device, including, tire, rotor wheel
Hub, bearing, motor stator, magnet exciting coil, permanent magnet；Described rotor hub is the conglomerate of rim for automobile wheel and rotor, its
Structure comprises rim structure, fin, air vent, rotor structure；Described tire is installed on outside the rim structure of rotor hub；
Described permanent magnet is installed on inside the rotor structure of rotor hub；Described bearing is installed in rotor hub bearing block；Described encourage
Magnetic coil is installed on motor stator；Described motor stator and bearing inner race pass through nut check.
Further, rim structure and the rotor structure junction of described rotor hub are provided with air vent, its arrangement
It is uniformly distributed centered by rotor hub axis.The function of this structure is that reducing heat-conducting section amasss, and prevents motor from turning when running
What the heat energy of minor structure was too much is transferred to rim structure, and meanwhile, air vent allows both sides gas to pass through, and takes away at rotor hub
Heat energy.
Further, described fin is evenly distributed on outside rotor structure centered by rotor hub axis, its structure
For arcuate structure.The function of this structure is to guide the gas inside wheel rim to circulate outside wheel rim, increases rotor structure simultaneously
Place's surface area, improves its radiating efficiency.
This utility model has the advantages that
Simple in construction, low cost, good heat dissipation effect, integrated level are high, can effectively reduce hub motor device quality.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The all other embodiments obtained, broadly fall into the scope of this utility model protection.
Such as Fig. 1, this utility model provides a kind of wheel hub motor rotor and hub for vehicle wheel integrated device, including, tire 1,
Rotor hub 2, bearing 3, nut 4, motor stator 5, magnet exciting coil 6, permanent magnet 7；Described rotor hub 2 is rim for automobile wheel and electricity
The conglomerate of machine rotor, its structure comprises rim structure 21, fin 22, air vent 23, rotor structure 24；Described tire 1 is pacified
It is loaded on outside the rim structure 21 of rotor hub 2；Described permanent magnet 7 is installed on inside the rotor structure 24 of rotor hub 2；Described
Bearing 3 is installed in rotor hub 2 bearing block；Described magnet exciting coil 6 is installed on motor stator 5；Described motor stator 5 and axle
Hold 3 inner rings to be locked by nut 4.When wheel hub motor works, magnet exciting coil 6 energising on motor stator 5 is mutual with permanent magnet 7
Effect produces magnetic torque, makes rotor hub 2 rotate, and drives tire 1 in ground surface.In motor process, magnet exciting coil 6
Producing a large amount of heat energy, a part is cooled down by motor stator 5, and a part is delivered at the rotor structure 24 of rotor hub 2.
Now, the bootable gas around that rotates of fin 22 circulates, and rim structure 21 is logical with rotor structure 24 junction
Air holes allows ambient gas to pass through, and takes away the heat energy at rotor hub, and meanwhile, louvre can reduce rim structure 21 and tie with rotor
The sectional area of structure 24 junction, reduces heat and is delivered to rim structure 21, affect pressure of tire.
By such scheme, by the integrated device of rotor Yu rim for automobile wheel structure, make wheel hub motor system structure
Simply, low cost, good heat dissipation effect, integrated level height.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
